# Internal attack pass before the freeze (F1 to F10)
The internal cryptanalysis pass of `docs/plans/cryptanalysis.md` section 4.2, run before the freeze tag
`cryptanalysis-target-1`, so the paid engagement confirms rather than discovers. The founder's word, 7 October 2026:
"make sure they find ZERO flaws". Every finding is ours, fixed and re-gated, before any firm starts.
Target: the hash class the chain runs after 0.3.15's flip, `igneum-pow` generator v4 `V4_CLASS` = `mx8+sh256x27`
(`LoadClass::MX8`, `ShadowClass { instrs: 256, reps: 27 }`), the acceptance rule, the verifier, the era draw,
the latency-shadow dataset and ladder, the chip and FPGA cost model. Scope and gates are section 1.1 and 1.4 of
the plan, the same tests the firm is held to.
Lane: attack-pass, worktree `igneum-wt-attack`, branch `attack-pass` from `origin/master` `ab99e5e3`.
Binary built on igneum-build-1 (ELF x86-64, `igneum-pow` 0.2.0, sha256 6d2867...1a9ebe5) and run there under
the box's slots; model and era work from `sim/horizon/algorithm/model.py` and `infra/fast-time/`. Each row below
carries the method, the known-failed shape where one exists, the result with numbers, and PASS, RUNNING,
BLOCKED or FINDING. PASS RECORD (7 October 2026, 16:0x UTC, 17:0x UK): every row reads PASS or FIXED-AND-PASSED. F1 PASS (AP-F1-1 on the
v5 list at 3.0 percent); F2 PASS, effort-bounded; F3 PASS; F4 PASS against class v4 (AP-F4-1 on the v5 list); F5
FIXED-AND-PASSED (the F2 hour skipped by decision); F6 PASS (the worst of 10^5 programs 8.708 ms on the half-core
proxy; O-1.14 closed on an i7-9700K); F7 PASS on all three sub-rows (the era VDF in the node, 0 of 6 re-rolls); F8
FIXED-AND-PASSED in class v4 sub-version 3 at 017e7037 (AP-F8-1, AP-F8-2, AP-F8-3 ours and closed; the four-seed
unattributed tail named); F9 PASS on (a) and (c), (b) closed by the same fix; F10 PASS. Frozen generator: class v4
sub-version 3, igneum-pow 017e70376489251e18564c0abce7e466e606c8b3, devnet epoch-0 id a785001687d8688a. The
freeze tag `cryptanalysis-target-1` is the coordinator's cut on this record; the era VDF precondition is met (F7 a). Main checks every number
against the log before quoting it to the founder.
## Status board
| # | Attack | Gate (same as 1.4) | Result so far | Status |
|---|---|---|---|---|
| F1 | Shadow block compressibility and shortcut search | no compression of the shadow block beyond the honest compiler's simplification, measured against that compiler on the same program; the 27 repetitions never fewer than 27x (coordinator's ruling 7 Oct 2026, 12:3x UK; the plan's gate (1) and row F1 carry the same) | 10^4 and 10^5 class v4 programs: saved instructions mean 0.62%, max 5.078% at 10^5 (1 of 100,000 over 5%, 0 over 10%); nothing folds or dedupes across the 27 passes; every saving is local peephole algebra that clang -O3 removes from the honest kernel too (IR counts match on the worst programs), so against the compiler the compression is 0; 0 mismatches in 2 x 10^5 differential and verifier checks, z3 window proofs 0 counterexamples. AP-F1-1 routed to the v5 list as a shadow redundancy bound. Record `docs/analysis/attack-pass/f1-shadow.md` | PASS; AP-F1-1 on the v5 list |
| F2 | Mixer round margin (SAT/MILP, 1 to 4 keyed applications) | no distinguisher or shortcut beyond 2 of the 8 applications | one application characterised (differential weight 10 to 12, linear 1, verified on the real code on three days); two applications: no trail at or below weight 20 to 24 within 7,200 s per job, the MSB and LSB families die at two; rotational-XOR no bias at one application; the multiply layer folds on 0 of 2^20 inputs, k applications cost k; three applications: no differential trail at or below weight 29 to 35 and no linear at or below 24 to 28, four: 39 to 47 and 24, every job at its 7,200 s cap. Record `docs/analysis/attack-pass/f2-mixer.md` | PASS (effort-bounded) |
| F3 | Chained cache j+1 bound and storage-vs-recompute curve | no derivation under j+1 blocks; curve monotone; f=1 point unchanged | 0 of 64 and 0 of 1,024 lines under j+1 (exhaustive closure search, cross-checked by exhaustive pebbling at 10 lines, 10,240 pairs, 0 mismatches); both planted broken chains fire; curve monotone at both op counts; f=1 point 9,360 ops per item unchanged. Record `docs/analysis/attack-pass/f3-cache.md` | PASS |
| F4 | Weak-day census over 2^24 day keys | fraction of days with gain over 1.1x under 2^-20 | PASS against M2 (DSP-bound datapath): 0 of 2^28 days over 1.1x; planted weak days fire; every ROT and RC class 0. Bound finding AP-F4-1 on M1 (LUT adders): 5,476 of 2^24 days (3.26e-4) over 1.1x as the tail of a sum, no weak class; worst public-calendar day 29,337 at 1.121x, at most 12.1% more rate that day for a per-day LUT FPGA, 0 for any chip; redraw rule (NAF sum under 163 rejected) routed to the next class. Record `docs/analysis/attack-pass/f4-weakday.md` | PASS (v4); AP-F4-1 routed to the next class |
| F5 | Chip-model sweep + AWS F2 FPGA hour | evidence row 17 holds across the sweep; FPGA row under 27 M reads/s/W | sweep: 2.1x at k=1 GDDR7 reproduces, 3.2x at k=0.5, 4.1x at k=0.3 (matches ledger M32); FPGA row 2.3 to 2.9 G/s, 10 to 20 M reads/s/W (literature). FINDING: the k=0.33 figure is framed as the X9's measured core (M32) and a "measured class" (ladder branch §5a); the X9 was withdrawn before launch and never benchmarked. F2 hour SKIPPED: no AWS account | FIXED-AND-PASSED (sweep PASS; AP-F5-1 fixed and re-gated 7 Oct 2026: chip section re-run 2.1x at k=1 unchanged, identity grep 0 hits, site lane concurred); F2 hour SKIPPED-BY-DECISION (the founder, 7 Oct 2026, 09:5x UK; plan 4.2 row F5 is the sweep only at 3714c2a0; the FPGA row stays the JEDEC-ceiling model row labelled unmeasured) |
| F6 | Verifier worst case over 10^5 programs + O-1.14 laptop run | worst program under 10 ms cold on the half-core proxy and the laptop | 100,000 programs ranked, 50,000 timed cold one-core (worst 6.194 ms), the worst 200 re-timed and the worst 1,000 timed on the half-core proxy under the per-core lease (core 40 at 3,799.9 MHz): worst 8.708 ms (`attack-f6/87142`), 1.29 ms under the gate, every half-core reading under 9 ms; dr736 fails as it must (15.49). O-1.14 CLOSED on an i7-9700K (v4 6.334 ms cold max, dr736 10.04 fails). Ladder ceiling from the worst program on the half-core proxy: N about 300,000, so rung 2 admissible, rung 3 not. Record `docs/analysis/attack-pass/f6-verifier.md` | PASS |
| F7 | Era-draw bias harness + 2^20 era-seed census | no re-roll inside the publish window; no era class with gain over 1.1x over 2^-20 | (b) census PASS at 2^24 seeds (no class over 1.1x, stride bijective, R, pos and M uniform, planted cases fire); (c) 64-bit day-key seeding PASS (0 collisions in 2^17); (a) PASS with the era VDF in the node (era-vdf lane, fork era-vdf-node 394a5902 on release-0.3.20-node c4459193, behind era_vdf_activation_daa; master a4eaf766 carries the spec text, `docs/analysis/era-vdf-2026-10-07.md` and `tools/era-vdf/reroll.mjs`): against the real era cut on three fast-time nodes the re-roll harness fires with the VDF off (6 of 6 cuts) and is silent with it on (0 of 6; the adversary's 5.4 to 6.6 s evaluation against a 1 s block interval, the honest chain 3 to 10 blocks ahead, three nodes agreeing on every era seed); the delay is 517 s on the fastest prover measured (chiavdf NUDUPL over GMP, 208.8K squarings/s) at T = 108,000,000, 259x the 2 s window. Open, not a gate: the verify is 22 ms against the 10 ms target (O-4.6, 0.3.22). Record `docs/analysis/attack-pass/f7-era.md` | PASS (a, b, c) |
| F8 | Uniformity censuses (line-index 2^28, distinct lines, cross-hash histogram) | uniform within the window model of spec 1.13.1, layer 8; the excess beyond it within 6 sigma over 64 seeds; no hot set under 1% of items beyond the model | line index PASS at 2^28. The 6 Oct stream: 31 of 64 seeds over 1.2x (AP-F8-1, the lossy load source). Sub-version 1 (8c728ca3): 11 of 64. Sub-version 2 (07a809a7 / 8bdcbdd8): 9 of 64; AP-F8-2 (exhaustion) closed there, 0 of 10^6. Sub-version 3 (017e7037: the acceptance executing the shadow block, AP-F8-3; the shared-operand rule; (c'') the distinct-index ratio): 60 of 64 under 1.2x, the four over the named unattributed tail at 1.22x to 1.50x with no chip consequence; 0 exhausted in 24,631 chain-shaped seeds, the draw total by construction. Record `docs/analysis/attack-pass/f8-uniform.md` | FIXED-AND-PASSED (sub-version 3, 017e7037, the frozen generator) |
| F9 | Acceptance edges (39) + header grinding on an RTX 5090 | zero passing programs with a hot set under 1%; grinding gain under 1% of rate | (a) edges on generator 4 over 10^5 seeds: 34 disagreements in 105,064 candidates (29 const_bit, 4 bias, 1 lane_const), every one a one-bit or sampling-noise property moving the choice to an attempt both stand-ins accept, nothing in the attacker's favour: PASS; (b) hot-set search over 10^6 seeds: 11,696 passing programs (1.17%) concentrate 1% or more of reads on a hot set, worst 17.3%: FINDING, the same or-saturation load-source class as AP-F8-1 found by a second harness (F9-1 merged into AP-F8-1), re-gated on the amended stream; (c) grinding on the 5090: +0.004% at K = 2^14, ceiling +43%: PASS. Record `docs/analysis/attack-pass/f9-grind.md` | (a) PASS; (b) the AP-F8-1 class on the 6 Oct stream, closed by sub-version 3 (F8's census is the re-gate instrument; this harness's hot-share metric counts the era's windows); (c) PASS |
| F10 | Ladder signal monotonicity harness | no step without 90% over 7 windows in either direction | known-fail fails, known pass passes; new cases on the exact-share driver: 89% up holds (no step), 89 then 90% down with restarts steps only at 90% after the 7-window cool-down, the floor holds under 100% down (never below rung 0); decision per seed block memoised, identical after a restart, never differs between nodes; 19 of 19 checks per case. Two items to main, not findings: a stale commit string in the ladder lane's igneumd, and proof-synced nodes deciding rung 0 until the witness lands (a precondition line for spec 01). Record `docs/analysis/attack-pass/f10-ladder.md` | PASS |
## The rows
### F1. Shadow block compressibility and shortcut search (hash lane)
Method: over 10^4 class v4 programs, constant folding, dead-register elimination, common subexpressions across the
27 repetitions, linear sub-block detection, SAT equivalence on reduced blocks; the minimum op count per program
against N. Known-failed shape: a shadow that constant-folds or dedupes across its 27 identical passes so a chip
pays fewer than 55,296 shadow instructions per hash. Entry point: `igneum-pow show --program-class v4` prints the
256-instruction shadow (op mix add=47 rotl=30 xor=30 shfl=29 mad=27 mul=22 sub=21 rotr=20 mulhi=18 or=12 on the
genesis seed). Gate: best compressed block within 5% of N on every program; no program over 10% compressible.
Result: RUNNING. What a failure moves: an acceptance-rule line for the shadow block (rule (c) runs the block),
packs re-cut.
### F2. Mixer round margin (hash lane, on the box)
Method: SAT or MILP differential and linear search on 1 to 4 keyed applications with drawn rotations; rotational-XOR
on the ARX layer; the fold of the multiply layer across applications checked algebraically. Known-failed shape: a
differential or linear trail or an algebraic fold that distinguishes or shortcuts more than 2 of the 8 applications
between dependent reads. Gate: no distinguisher or shortcut beyond 2 of the 8 applications. Result: RUNNING (prior
`ca2-mixer` evidence to be re-gated). What a failure moves: `mixer_mult` 16 or a shape change; verifier re-measured.
### F3. Chained cache j+1 bound and storage-vs-recompute curve (hash lane, on the box)
Method: exhaustive search on a 2^10-line model segment for a line derivable without an earlier line; the curve from
f = 1/64 to 1 in ops per item. Known-failed shape: a line (s, j) computable in fewer than j+1 block evaluations
without an earlier line (the MTP address-steering break shape). Gate: no derivation under j+1 blocks; curve monotone;
f=1 point unchanged. Result, 7 October 2026, 09:10 to 09:12 UK on the box (`docs/analysis/attack-pass/f3-cache.md`; logs
`/srv/builds/igneum-wt-attack/attack-f3/r1-*.log`): PASS on all three clauses. The chain extracted from
`Cache::fill_segment` (verified equal to the code on 16 of 16 key and segment pairs; `block == chacha_block` on
100,000 random inputs) has line j fed by line j - 1 only; the exhaustive closure search finds 0 of 64 and 0 of
1,024 lines under j + 1 (every line costs exactly j + 1), cross-checked by an exhaustive pebbling search at 10
lines (10,240 configuration and target pairs, 0 mismatches). The two planted chains fire: `skip2` (63 of 64 under
j + 1) and `nofeed` (every line in 1 block). The curve over stored cache lines is monotone non-increasing from
f = 1/64 to 1 at 608 (counted) and 700 (MEMHARD.md) ops per block; the f = 1 point is 9,360 ops per item,
41.7 MH/s at the 50 T op/s budget, unchanged. `ca2-cache` was the hot-table experiment, not a chain analysis, so
there was nothing to re-gate. Observation (coordinator and the F3 record, not a finding): `funding.md` B2 rank 2
prices the trade-off at the naive placement; the optimal placement of every 8th line costs 3.17 blocks per read,
not 3.5, and 16.0 at f = 1/64, not 31.5 (brute force over 4,426,165,368 sets at n = 8); the chip stays worse than
the full mirror at every f under 1, so the verdict stands, and a `chacha_block` shortcut in chaining mode stays
the paid question (Lot A and B). What a failure would have moved: the chain construction (a second feed-forward or
a cross-segment tie).
### F4. Weak-day census over 2^24 day keys (hash lane, on the box)
Method: 2^24 day keys through `MixParams::with_shape`; the ROT classes (all equal, complementary pairs, small
amounts), MUL low weight, RC structure, each per-day gain measured on the box verifier. Known-failed shape: a day
key whose drawn ROT/MUL/RC gives a fixed datapath a gain over 1.1x (the "weaker authorized parameters" class,
Kudelski 2019). Gate: the fraction of days with any gain over 1.1x under 2^-20. Result: RUNNING. What a failure
moves: a rejection-and-redraw rule on the draws.
### F5. Chip-model sweep and the FPGA hour (algorithm lane)
Method: `sim/horizon/algorithm/model.py` over k 0.2 to 1.5, tFAW 12 and 28 ns, HBM4 2.3 and 21.4 G reads per
stack, amortisation 1 to 3 years, electricity USD 0.05 to 0.15 per kWh; and the AWS F2 hour replacing the FPGA
ceiling row with a measurement. Known-failed shape: an input of the published model that, when corrected, lifts the
f=1 chip's per-joule edge over the 5090 above the published 2.1x at k=1.
Gate: the published sentence (evidence row 17) holds across the sweep; the FPGA row under 27 M reads/s/W.
Result (sweep): PASS on the numbers. The model's measured-anchor column (GDDR7, the 5090 reads 82% of its ceiling)
gives the f=1 chip's v4 per-joule edge over the RTX 5090 bench row as 4.1x / 3.2x / 2.1x / 1.5x at k = 0.3 / 0.5 /
1 / 1.5. At k = 1 the figure is 2.1x, and 3.9x at k about 0.33, which matches `fud-ledger.md` M32. The higher HBM3
and HBM4 columns rest on an 8-activate per 12 ns window that JEDEC HBM2 timings (4 per 28 ns) do not support; the
model already states GDDR7 is the column to quote. One wording gap: `evidence.md` row 17 says "brings it to about
2x", which is a floor that holds at k about 0.9 and above but understates the edge at lower k (3.2x at k = 0.5). The
accurate statement is M32's, 2.1x at k = 1 with the k range beside it. The sweep's numbers stand; the finding is the
X9 framing below.
FPGA row: the HBM2 FPGA ceiling is 2.3 to 2.9 G reads/s (measured Shuhai U280, FCCM 2020, equal to the JEDEC
tFAW-bound 2.3 G/s), 10 to 21 M reads/s/W at 115 to 150 W, 0.30 to 0.47x of the 5090 per watt. Under the 27 M
reads/s/W gate. The AWS F2 hour is SKIPPED-BY-DECISION (the founder, 7 October 2026, 09:5x UK: not needed for now, not blocked;
plan 4.2 row F5 at commit 3714c2a0 on branch cryptanalysis is the chip-model sweep only, 4 h, the algorithm lane).
There is also no AWS account or `aws` CLI on this Mac. The FPGA row stays the JEDEC-ceiling model row labelled
unmeasured; Lot C prices it from the reads-in-flight model; the firm is told the F2 measurement was not run.
FINDING (X9 framing), owning lane algorithm and hash (the ladder lane is closed, so ours): the published numbers
already carry 2.1x at k = 1 beside 3.9x at k about 0.33 (`fud-ledger.md` M32, recalibrated under X35). The error is
the framing. M32 calls the k = 0.33 figure "the X9's core" and the `ladder` branch's `latency-ladder.md` section 5a
calls k about 0.33 a "measured class". Bitmain's Antminer X9 (RandomX ASIC, 1 MH/s, 2,472 W, about USD 5,600) was
announced and, per pcpraha.cz ("Antminer X9 canceled: Bitmain withdraws model from market before launch") and
r/MoneroMining, withdrawn before launch. Its implied core efficiency (k about 0.33) is a CLAIMED datasheet figure
from a design that never shipped and was never benchmarked, not a measured calibration point. It is carried as the
pessimistic bound, not a calibration. This collides with the merged ledger X34 ("RandomX has a shipping chip;
correct every sentence that said otherwise"): if the X9 was withdrawn, X34's correction is itself wrong and must be
reversed. Confirmed from primary sources (coordinator, 7 October 2026): pre-orders opened 26 December 2025 (shipments
scheduled for July 2026), withdrawn in mid-May 2026 with buyers refunded before any unit shipped, no independent
benchmark, Bitmain never published a cancellation (its shop lists it as sold out), and the box was commodity Sophgo
SG2044 server SoCs with an AES accelerator and 60-plus DRAM sticks, no tapeout; its claimed edge about 2x per joule
over a tuned Zen 4 part, about 3x over a stock desktop CPU. Re-cut applied the same day: `evidence.md` row 17 (claim
and measured cells) and `fud-ledger.md` M32's answer paragraph on attack-pass, and the ladder design doc section 5a
on branch `attack-ladder-5a` from the ladder tip 7003f9f5 (the `ladder` branch is checked out by another lane, so
the fix rides its own branch for the ladder owner to take). The served-text rows (X34 reversal, X36) belong to the
site lane, which confirmed the wording agrees. What a finding moves
(plan 4.2 F5): the sentence re-cut before the freeze so the firms attack the corrected model. The re-cut, once the
fact is confirmed: k about 0.33 labelled a claimed pessimistic bound from a withdrawn design everywhere it appears;
2.1x at k = 1 on the GDDR7 measured anchor kept as the headline with the k range beside it; k itself unmeasured
until Lot C produces it. This row reads FIXED-AND-PASSED only after the re-cut and its re-gate.
Economic row the withdrawal implies: a recompute chip at a 3x fixed-function factor against a CPU and GPU fleet
must recover its NRE (low to mid seven figures at a modern node, `chip-model-v3.md`) and carry a fork threat (a
class change at 95% miner signal can redraw the datapath the chip bakes in). The X9 at 2.47 J per KH against a
RandomX CPU fleet did not clear that bar at Monero's hash and price; the same arithmetic against Igneum's class v4,
with the shadow block and the automatic era draw as extra firmware risk, is why the chip model's verdict is a
deliverable and not a courtesy (plan 2.3). The confirmed reading: a box with a 2x to 3x per-joule edge and no NRE (commodity SoCs) was withdrawn rather than
face a 1.5x re-tune of RandomX, so the tapeout economics of a 3x chip against Igneum are worse than the X9's. This
row is the pessimistic case, not a measured gain.
### F6. Verifier worst case (algorithm lane)
Method: 10^5 class v4 programs timed on the box one-core and half-core proxies for the slowest warp (base program
and shadow block), plus the O-1.14 laptop run (the Windows `igneum-pow` build on the box, the relay, `bench
--warps 50`). Known-failed shape: a drawn program whose verifier warp exceeds 10 ms cold (the acceptance rule bounds
the miner's side, not the verifier's; `dr736` already FAILs at 10.51 ms cold one-core, but it is not the shipping
class). Gate: the worst program under 10 ms cold on the half-core proxy and on the laptop.
O-1.14 route (coordinator, 7 October 2026, 10:1x UK): no US laptop is due, so the laptop run is replaced by a
rented 2019-class CPU host through the fleet agent, capped at two hours of rent; the Linux `igneum-pow` from the box
(the same binary as the proxies) runs `bench --warps 50` for v2, mx8, mx8+sh256x27, dr368 and dr736 (the
known-fail) on it; INCOMPLETE with the numbers so far if the cap lands first. The Windows exe was also built on the
box for the day a laptop appears (1,009,675 bytes, sha256 fbed7538...e6c9). Outcome, 09:40 UK: no 2019-class CPU
host stood up. Vast accepted and dropped five CPU-class rents within 30 s each (i7-9700K, i5-8500, Xeon W-2133 and
W-2123) under the account's automatic new-account spend limit (support ticket open since 6 October), and RunPod has
no 2019-class CPU pod; so O-1.14 reads INCOMPLETE on the box proxies today and stays a precondition of the freeze.
Next try: the US laptop when it registers on the relay (the exe is ready), or Vast once the spend limit lifts; the
bench script is staged and runs in minutes. Correction, 10:4x UK (fleet agent): the provider dropped nothing; every
rent stood up and ran, hidden by Vast's instance listing cap of 25 rows on an account holding 38, so the hosts sat
idle and were destroyed. The fallback is re-rented under the same word (i7-9700K class, two-hour cap from its start,
read by id); the result replaces this line when it lands.
O-1.14 RESULT, 7 October 2026, 09:49 UK, Vast instance 54613164, Intel Core i7-9700K (2019 desktop core, Coffee Lake,
read at 4,170 MHz during the run, 31 GB DDR4, Ubuntu 24.04), the box-built Linux `igneum-pow` (sha256 6d286783...),
`bench --seed igneum-genesis --day 2026-10-03 --warps 50` on one core (`taskset -c 1`), the host otherwise idle; log
`docs/analysis/attack-pass/o114-i7-9700K-2026-10-07.log`:
| Class | Cold max (ms per warp) | Average of 50 (ms) | Gate 10 ms | Box one-core cold | Box half-core |
|---|---|---|---|---|---|
| v2 | 1.582 | 1.280 | pass | 1.30 | n/a |
| mx8 (class v3) | 5.394 | 5.267 | pass | 4.67 | 7.56 |
| mx8+sh256x27 (class v4, the target) | 6.334 | 6.006 | pass, 3.7 ms of headroom | 5.06 | 8.23 |
| dr368 | 5.540 | 5.426 | pass | 5.32 | 8.16 |
| dr736 (the known-fail) | 10.290 | 10.042 | FAIL, as it must | 10.51 | 15.49 |
Cache fill 276 ms on the 9700K core (box 361 ms, M5 Max 175 to 181 ms). The 2019 desktop core sits between the box's
two proxies as the arithmetic predicted (1.2x the box one-core cold on v4, 0.77x the half-core); the known-fail
fires on it. A 2019 laptop core at 3.5 GHz reads about 15 to 20 percent slower than this desktop part (approximate,
clock ratio), so about 7.0 to 7.6 ms on v4, still under 10 ms. Consequences: a 2019-class node verifying class v4
spends 0.6 percent of one core at 1 bps and 6 percent at 10 bps; a header flood needs about 160 invalid headers a
second to saturate one such core; a pool verifies about 160 shares a second per core; IBD of 108,000 headers is
about 11 minutes of one core. The implied ladder ceiling on this core: the shadow costs 0.74 ms per 55,296
instructions (v4 minus mx8), so the 4.0 ms of headroom buys about 300,000 more shadow instructions, N about 650,000
counted ops at the 1.83 convention (approximate), against 370,000 on the half-core proxy and 1,060,000 on the
2.5x rule; the half-core proxy stays the standing pessimistic rule and the ladder's ceiling should be taken from
it, not from this desktop part. O-1.14 is CLOSED on a real 2019-class core for the genesis program; the F6 row
still owes the 10^5-program worst case before it reads PASS.
Result (average, verified on the box): class v4 `mx8+sh256x27` runs 4.90 to 5.06 ms per warp cold on one EPYC
9454P core (nice 19, taskset), 8.23 ms on the half-core proxy (both SMT siblings busy). Under 10 ms. Status
RUNNING: the 10^5-program worst-case search and the O-1.14 laptop relay run are owed before the row reads PASS.
What a failure moves: an acceptance-rule bound on verifier cost; the ladder's ceiling set from the measured core.
### F7. Era-draw bias harness and census (node lane harness, hash lane census)
Method: the fast-time 3-node network (`infra/fast-time/`) with an adversary withholding or publishing the last blue
block before C_era(n) to re-roll the draw; a census of 2^20 era seeds for stride, ROT and weight-perturbation
classes with gain over 1.1x; the 64-bit seeding of the day-key stream against the spec's intent. Known-failed shape:
a re-roll of the era draw inside the 2 s publish window, or an era class (stride bijection, all-equal ROT, low-weight
M) with a chip gain. Gate: no re-roll inside the publish window; no era class with gain over 1.1x at a fraction over
2^-20; the draw's input set as the spec states it.
Result (full record `docs/analysis/attack-pass/f7-era.md`; harness `tools/attack/f7-era/`). Census: 2^20 and 2^24 era
seeds through `generator::era_draw` over `V3_ALLOWED` (the chain's path), classified; the planted known-fail/known-pass
of the classifier fired and the sound draw raised nothing. No era class with gain over 1.1x at any fraction (the richest
is M = 1 at 1.0034x, absent in 2^24; every class over 2^-20 is 1.0000x to 1.0007x); the stride is a bijection on every
sample (0 even M), R and pos and the M bits uniform; the op-weight corners (15 to 31 of 75) are 1.0x against the GPU, 0
memory effect. The 64-bit day-key seeding is the spec's intent (spec 1.8.4); 2^16 days are all distinct, birthday 2^-33.
Harness: the 3-node fast-time network (`reroll.mjs`, ports 29800+, suffix 980) with an adversary holding the last block
before the cut; known-pass (`--vdf-ms 0`) fires at 1 of 6 cuts (seed = adversary block), known-fail (`--vdf-ms 5000`)
is silent at 0 of 6, both SOUND. The node has no era VDF yet (`seed_below` is a plain block hash, era-layout.md section
8), so the harness cannot show the real 2 s-window gate; the era draw's grinding resistance rests on the 1-hour VDF of
spec 4.4 (re-roll needs a 1,800x evaluator, spec 4.6 gives 300x; forge needs 20 days of 100% hash). Verdict: census PASS,
64-bit seeding PASS, harness INCOMPLETE with the written argument. Logs on igneum-build-1
`/srv/builds/igneum-wt-attack/attack-f7/census-2p24.log`, `census-2p20.log`, `reroll-knownpass.log`, `reroll-knownfail.log`.
What a failure moves: the draw procedure or the C_era cut rule; a redraw rule for the era stream.
Sub-row (a) CLOSED, 7 October 2026, 15:1x UK (the era-VDF lane, launched by the coordinator on this row's INCOMPLETE):
the era VDF is in the node (fork `era-vdf-node` 394a5902 on `release-0.3.20-node` c4459193, behind
`era_vdf_activation_daa`, never on any network until the founder sets it per network; repo master a4eaf766 carries the spec
text, the record `docs/analysis/era-vdf-2026-10-07.md` and the harness `tools/era-vdf/reroll.mjs`, which attacks the
era cut directly now that the node takes `pow_era_blocks` and `pow_era_lead` from the override file). Against the
REAL era cut (era 120 DAA, lead 20 on the fast-time file, three nodes on igneum-build-2) the harness fires with the
VDF off (6 of 6 cuts: the adversary's block is the cut block and its hash the seed, known the instant it is built) and
is silent with it on (0 of 6 across six cuts: the adversary's 5.4 to 6.6 s evaluation with the node's own code against
a 1 s block interval, the honest chain 3 to 10 blocks ahead when it published, three nodes agreeing on every era seed,
the record ready at every era start). SOUND both ways. The production delay: 517 s on the fastest prover measured
(chiavdf NUDUPL over GMP, 208.8K squarings/s on the same core) at T = 108,000,000 squarings, 259x the 2 s window.
Freeze sentence (the era-VDF lane's, carried to the plan's owner): "The era seed E_n is the output of a one-hour
verifiable delay (class-group Wesolowski, 1,024-bit prime discriminant, T 108,000,000, scheme byte 0 with the
hash-chain fallback as byte 1) over the blue blocks of the day ending at the era's cut block; the attack pass's F7
re-roll harness fires against the stand-in and is silent against the delay, so the era draw procedure and the C_era
cut rule are frozen with the VDF in the node, behind era_vdf_activation_daa, never until set per network." Open, not
a gate of F7: the verify is 22 ms with the group held, against the 10 ms target (once per 180 days per importing
node; O-4.6's reducer or GMP behind a feature, 0.3.22). Logs `/srv/builds/igneum-wt-era-vdf/ev-harness-out/
reroll-vdf-{on,off}-5.json` on build-2. F7: PASS on all three sub-rows.
### F8. Uniformity censuses (hash lane, on the box)
Method: the line-index distribution over 2^28 derivations; distinct lines per hash and per warp on 10^6 nonces of
three programs; the cross-hash item histogram of one epoch. Gate: the largest bucket within 6 sigma of uniform; no
hot set under 1% of items. Result: RUNNING. What a failure moves: the mask or the fold; packs re-cut.
### F9. Acceptance edges and header grinding (hash lane; one PC 2 job)
Method: the 39 edge disagreements reproduced and bounded; a search over 10^6 seeds for programs that pass rule (c)
with a hot set under 1%; the header-grinding search cost against its DRAM-locality gain measured on PC 2's RTX 5090
(one job through `tools/build-job.mjs`). Known-failed shape: a seed grind that steers a program to a hot cache set
for DRAM locality, or an edge where the closed-form stand-in disagrees with the live verifier in the attacker's
favour. Gate: zero passing programs with a hot set under 1%; the grinding gain under 1% of rate at any search cost.
Result: the `accept` path reproduces per-seed verdicts (genesis seed: 1 candidate ACCEPTED, bias max 54, 0
saturated). The header-grinding cost-versus-gain measurement needs a 5090. Status BLOCKED on the go decision: use
PC 2's 5090 through a relay run job only if PC 2 is online and mining is unaffected, else a rented pod under the
standing fleet budget. What a failure moves: the closed-form stand-in replaced by the live verdict at the edges; a
locality term in rule (c).
### F10. Ladder signal monotonicity (node lane)
Method: the fast-time harness with a weight that steps the ladder down and never up, and an 89% signal; the step
rule's monotonicity and its memoisation per seed block. Known-failed shape: a chip owner stepping the ladder down
(cheaper N) without the 90% threshold, or a step registered under 90%. Gate: no step without 90% over 7 windows in
either direction; a step down needs the same. Result: RUNNING. What a failure moves: the step rule's text in spec 01
before the ladder is frozen.
## Lane (d): the families re-run on class v5 (7 October 2026, evening; the coordinator's word on the founder's order)
Object: igneum-pow on branch `class-v5` at e4f1f275 (the frozen sub-version 3 017e7037 merged; the v5 chain draw is
the amended v4's instruction for instruction, generator 5, every item keyed by the window's state through the leaf
XOR before the first mixer; `V5_CLASS` = `mx8+sh256x27+state`), against the first v5 pack
`proto-cuda/packs-ca3-v5/v5-dn3-epoch0` (Devnet 3's genesis 4020cb43... as epoch and era seed, day 20,733, program id
e5a4ac5978462156, reproduced by the e4f1f275 build on box 2: the pairing). The four harnesses carried onto the
class-v5 tree in worktree `igneum-wt-attack-v5` (branch `attack-v5`), each with `--class v5` and, where the dataset
enters, `--state <IGSD1>` attaching the leaves through `with_leaves` as the CLI does; F8's traced derivation carries
the leaf XOR and validates bit for bit against `derive_items_leaves` and `Epoch::hash_warp` (p1 on the dn3 state at
4,096 nonces: 0 mismatches over 16,777,216 items and 64 warps; the flipped-state file mismatches: the known-fail).
Both boxes at nice 10 beside the release builds; the binaries run from copies in each run's scratch directory (AP-H2).
GitHub answered 403 (account suspended) from 17:2x UK, so this section lands on the box mirror (`build`, master and
attack-pass) by the coordinator's exception rule; nothing touches GitHub.
| Family | Class v5 run | Result | Verdict |
|---|---|---|---|
| F4 weak-day census | 2^24 chain days from 20,729 under `Shape::for_class(&V5_CLASS)`, box 1, 18:5x to 19:1x UTC | byte-identical to the class v4 census: M2 (DSP-bound) 0 of 2^24 days over 1.1x; M1 (LUT adders) 5,476 days, 3.264e-4, the same bounded tail, worst day 4,819,563 at cost 197 against the median 231; planted weak days fire (mul1all M2 unbounded, mulnaf 1.333x). The day-key draw depends on the mixer shape alone and v5 adds only the state flag, so identity is the expected and the measured result | PASS (v4's reading; AP-F4-1 stays the next-class item) |
| F8 hot-set gate | 64 seeds at 2^24, chain path, v5 with the dn3 state, box 2 (64 threads), from 18:47 UTC | pending | pending |
| F9 exhaustion count | 10^5 chain-shaped seeds on the v5 chain path with the dn3 state, box 1, ten parallel chunks (the chain draw costs about 2.2 s per candidate through (c''), so 10^6 is about fifty hours) | pending | pending |
| F1 shadow redundancy | 10^5 class v5 programs through the string-seed path, box 1 | pending | pending |
## Operating hazards found by the pass
AP-H1 (box scratch cleaned by builds; found by F3, 7 October 2026, 10:0x UK). `infra/build-server/remote-run.sh`
line 71 runs `git clean -qfd -e target -e 'target-*' ...` on `/srv/builds/<worktree>` before every remote build, so
an untracked box scratch directory of one row (a venv, a log dir, a crate's `tools/attack/*/target`) is deleted by
the next build from any row. F3 protected its own directory through the box mirror's `.git/info/exclude`; the lane
then added `attack-*/`, `target-attack-*/`, `tools/attack/` and `.build-remote.log` to that file at 10:1x UK, after
which `git clean -fdn` on the mirror lists nothing (the clean has no `-x`, so the exclude file applies). The class
check is owed to the build-server lane: the clean line should spare a lane's declared scratch prefix (`-e 'attack-*'`
style, or read a per-worktree exclude list), and a CI check should fail a remote-run.sh whose clean line lacks it.
OPEN until that check lands (CLAUDE.md: a rule row closes only with its check).
AP-H2 (this lane's own, 7 October 2026, 13:3x and 14:5x UK, twice). Two census runs launched from the same crate's
`target/release` binary path on the box mirror: a rebuild of the crate at a new commit replaces the binary under a
run still in progress, and every chunk the run launches after that executes the new commit's code with the old run's
label (the 07a809a7 control's later chunks ran 8bdcbdd8; the ddacfbd3 class check's later chunks ran 017e7037). Both
runs were caught by their attempt histograms (attempts 32 and 35 under a cap of 32) and their contaminated chunks
discarded. Fix in the lane's launcher: `run-census-chain.sh` copies the binary into the run's own scratch directory
before the first chunk and runs from the copy, so a rebuild cannot reach a run in progress; a run's record names the
sha256 of the copy. Class check owed: the same rule for every lane's long run (the box's build runner could refuse to
replace a binary that a running process has open, or stamp the commit into the run's log at every chunk).
## Ledger rows
AP-F1-1 (hash lane; ruling asked). At 10^5 class v4 programs one program (`attack-f1/37341`) compresses by 5.078
percent (13 of 256 shadow instructions per pass), 0.078 points over the gate's first clause, on 1 of 100,000; every
other program is within 5 percent and none over 10. The saving is the same local shape as on every program (a
register written twice from one source with no write between), nothing crosses a pass, and clang -O3 removes the
same instructions from the honest kernel (IR counts match the harness on the worst programs), so a chip gains nothing
relative to a card: no shortcut. The gate as written counts honest-compiler simplification as compressibility. Two
ways to close: re-word gate (1) and row F1 to "compressible beyond the honest compiler's own simplification" (the
firms then attack chip-relative compression, which is the question), or a shadow-draw redundancy bound in the next
class (reject a shadow with over 12 peephole-removable instructions per pass, rejection about 1e-5; class v4 is on
the live vote). Ruling (coordinator, 7 October 2026, 12:3x UK): both. Gate (1) and row F1 re-worded to "no
compression of the shadow block beyond the honest compiler's simplification, measured against that compiler on the
same program" (sent to the cryptanalysis lane for the plan and the firms' brief), under which the 5.078 percent
letter miss at honest-compiler parity is a PASS; and a shadow redundancy bound on the v5 generator's list beside
AP-F4-1 and AP-F8-1 (the generator refuses a shadow block whose honest-compiler simplification exceeds a stated
fraction; the v5 lane sets the fraction from F1's census), gated by F1's harness on 64 seeds of the v5 stream.
The fraction is 3.0 percent (v5 lane, class-v5 45e29cb0; 384 of 100,000 draws redrawn in its census, 3.8e-3, against
F1's histogram where the 3.0 to 5.5 percent bins hold 397 of 100,000); the plan's 1.1 sentence carries the number.
Status: F1 PASS; AP-F1-1 FIXED-AND-PASSED against v5 once the bound is in the v5 generator and F1's census passes.
AP-F5-1 (algorithm and hash lane, ours; the ladder lane is closed). The k about 0.33 chip-efficiency figure is
framed as a measured calibration ("the X9's core", `fud-ledger.md` M32 L172; "measured class", `ladder` branch
`docs/design/latency-ladder.md` section 5a). The Antminer X9 was withdrawn before launch and never benchmarked, so
k about 0.33 is a claimed datasheet bound, not a measurement. This also puts the merged ledger X34 ("RandomX has a
shipping chip") in question. Fix owed, held until the coordinator's research agent confirms the withdrawal and the
no-benchmark fact: relabel k about 0.33 as a claimed pessimistic bound from a withdrawn design in `evidence.md` row
17, `fud-ledger.md` M32 and the `ladder` branch; reverse X34 if the withdrawal is confirmed; keep 2.1x at k = 1 on
the GDDR7 measured anchor as the headline with the k range beside it. Re-gate after the re-cut. Status: FIXED on the docs rows (evidence 17, M32, ladder 5a on branch attack-ladder-5a d3cb17b6; attack-pass
rebased on master a3678789 after X36); FIXED-AND-PASSED once the site lane's X34/X36 served rows are confirmed in
one voice (no objection received) and the sweep is re-run against the re-cut sentence (the numbers are unchanged, so
the re-gate is the identity check and one `model.py --section chip` run against the new wording). Re-gate done 7 October 2026, 09:5x UK: the 5090
bench row still reads 5.7x / 4.1x / 3.2x / 2.1x / 1.5x (v3; v4 at k = 0.3 / 0.5 / 1 / 1.5), identity grep 0 hits
over 290 export files, the site lane confirmed the served text agrees. AP-F5-1: FIXED-AND-PASSED.
AP-F8-1 (hash lane; the generator fix is the Counter ASIC lane's on the v4 seam, routed 7 October 2026, 10:3x UK).
The class v4 item read map is not uniform. F8 phase D, one program, 2^26 nonces: the top 0.1 percent of items take
0.520 percent of reads against 0.115 percent for the uniform control (4.05x); the top 1 percent take 2.49 percent
(1.37x); one item (0xca5b92) takes 78,479 reads, 153x the mean; read site 15 feeds 6.37 percent of its reads into
that 0.1 percent in all 8 iterations; the excess grows with N as a real skew does. Sized: a chip caching the hot
0.1 percent in SRAM serves about 0.5 percent of reads from cache, so the shortcut is under one percent of rate today;
an auditor flags a non-uniform read map in a design that claims uniform random reads, and site 15's index derivation
is the cause to name. Fix asked: per-site index whitening or a rejected class above a bound. Re-gate: the top
0.1 percent within 1.2x of the control over 2^26 nonces on every one of 64 seeds, with F8's harness against the
Counter ASIC lane's branch. Phase E (the 64-program census) decides whether it is one program or the class.
Framing from the Counter ASIC lane (the generator's owner, 7 October 2026, 10:5x UK): class v4's item map is not
designed to be uniform per program. Layer 8 (spec 01 section 1.13.1) gives each load site k_off = below(3), so a
site reads the whole dataset, a half or a quarter under the era's stride and interleave; a quarter-window site
concentrates 4x on its quarter by design, which is the 4.05x at the top 0.1 percent, and the windows exist so a
chip's SRAM mirror must hold the whole dataset every hour (the Counter ASIC 2.0 windows-union census). The right
control is therefore the window model from the program's own 16 draws, reported beside the uniform control (what an
auditor sees first); the number that must be explained is the single item 0xca5b92 at 153x the mean (window
coincidence under the era mapping with a stated tail, or a low-entropy index source at site 15, which would be a
fault). The lane reproduces with F8's harness on branch `ca3-v4-uniform`, waits for phase E, re-prices the chip
consequence (a 0.1 percent hot-set cache, about 1.7 MB of SRAM, serving 0.5 percent of reads: under one percent of
rate) and changes the generator only on a fault beyond the model, since v4 is on the live devnet's vote. F8 was
re-briefed to carry both controls and the per-site table. Raised to the coordinator: plan 1.4 gate (4) and row F8
say "within 6 sigma of uniform"; if the design is windowed, the gate text must say "uniform within the window model
of spec 1.13.1" before the freeze tag, or every reviewer files the windows as a finding on day one.
Coordinator's ruling (7 October 2026, 11:0x UK), accepted: the right null is the window model derived from the
program's own draws; F8 is re-gated against it, and the finding stays open only for the excess beyond the window
model (the 153x item, or a low-entropy source at site 15 if the 64-seed census shows one). No generator change to
class v4 is allowed: it is on the live devnet's vote, and a class change before the flip splits the chain. If the
census shows a real fault it goes to the coordinator priced; otherwise the record carries the documented null and
the hot-set bound (a 0.1 percent cache, about 1.7 MB of SRAM, under one percent of rate) goes into the next class.
Gate wording settled (coordinator, 11:2x UK): plan 1.4 gate (4) and row F8 now read "uniform within the window
model of spec 1.13.1, layer 8; the excess beyond it within 6 sigma over 64 seeds", carried into the plan's scope
text by the cryptanalysis lane so the firms are briefed on the windows before they start.
Mechanism (hash lane, branch `ca3-v4-uniform` 095f84a7, `docs/analysis/ca3-v4-uniform.md`, harness
`tools/ca3-v4-uniform`, 7 October 2026, 12:3x UK): the windows-union null (a Poisson mixture at 416 / 288 / 736 / 608
reads per item by quarter from the program's 16 draws) moves the top 0.1 percent from 0.115 to 0.160 percent, 1.39x,
not 4.05x; every per-site row of F8's attribution except site 15 is the window model. The rest is the LOAD SOURCE:
site 15 is the load at 63 reading r6, whose last writer is `or` at 61 (r6 = r6 | r4), so the source is all-ones with
probability about (3/4)^32 per read; under the era map x = 0xffffffff is item 0xca5b92, the hottest item exactly, and
the next seven hottest are the seven one-zero-bit sources whose zero survives the window mask (7 of 7); the measured
count fixes the bias at p = 0.7585 per bit. The class: a load whose source's last writer is lossy (or: 0.30 percent
of a site's reads on 0.1 percent of values; mul, trailing zeros: 1.07; mulhi: 0.79; an or of an or: about 4.5).
Static census of 1,024 chain-shaped v4 programs: 96.6 percent carry a lossy-sourced load (48.5 percent or, 4.9
percent an or chain, 73 percent mul, 64 percent mulhi); predicted S_0.1 median 0.45, 90th 0.88, 99th 5.3, max 9.8
percent; p1 / p2 / p3 predicted 0.58 / 0.32 / 4.72 against measured 0.52 / 0.27 / 4.60. The fault sits in the
acceptance rule's blind spot: part (a) takes any write as fresh, part (c) counts saturation on final values only.
Consequence: the 1.2x-against-window gate fails 96.6 percent of today's programs, so it is withdrawn as a v4 gate and
becomes the v5 generator item's gate (draw a load's source from registers whose last writer injects; a dynamic check
counting saturated load sources), with F8's phase E as its test. Chip side: the top 0.1 percent of items is 1.07 MB
of SRAM (0.53 mm^2, about USD 0.25) serving 0.52 percent of p1's reads and 4.6 percent of p3's, at most 1.005x and
1.048x in rate; the ceiling under rule (c)'s 120-of-128 floor is one site repeating its item in all 8 iterations,
6.25 percent of reads, 1.067x. That 1.067x is the v4 hot-set bound the record carries. No generator change to v4;
the hash lane takes the two flip options priced to main.
Ruling (the founder, 7 October 2026, 15:2x UK): option A, the class v4 amendment ships in 0.3.20, the feature node (0.3.19 is the app-only cut on the unchanged 0.3.17 node pin; corrected by the coordinator) (a load's source drawn
only from registers whose last writer injects or is a rotate, the v5 rule applied now; a new program stream and
seven re-exported packs on branch `ca3-v4-amend`, the hash lane), with limited testing. This lane's part is the proof
of the fix: F8's hot-set census at 2^24 nonces on each of 64 seeds of the amended stream, on the box's CPU path as
phase D ran, gate: the top 0.1 percent of items within 1.2x of the window model derived from each program's own 16
window draws, one number per seed; reported to the hash lane, main and the Counter ASIC lane. The amended stream has
no lossy-sourced load by construction, so a seed over 1.2x there is a finding against the model's own tail, not the
fault, and the record says which.
Second harness (F9 sub-row b, 10^6 seeds, 12:5x UK): the same class from the other side, the per-site address trace:
11,696 of 1,000,000 passing programs concentrate 1 percent or more of their reads on a hot set (worst 17.3 percent,
seed 842871, an `or`-written load source all-ones in 36 percent of evaluations), so F9-1 merges into AP-F8-1 and
F9's harness is the second re-gate of the amendment, run on the amended stream beside F8's 64-seed census.
Re-gate interim (7 October 2026, 13:2x to 13:5x UK, box 2): F8's 64-seed census at 2^24 nonces against the amended
stream (igneum-pow 8c728ca3, sub-version 1; pairing verified, the harness draws the devnet epoch-0 program as
1a4230699a6b9c60) at 30 of 64 seeds shows nine over 1.2x of the window model (p31 29.27x, p11 5.45x, p19 3.32x, p6
3.11x, p23 2.04x, p4 1.57x, p10 1.50x, p26 1.30x, p25 1.28x), p6's hottest item predicted from "site 13, r0,
all-ones, last writer a load at 12": a load-after-load chain (a hot address yields a fixed dataset word, which is the
next load's address), which the source rule admits because a load injects. Rule-level reading, checkable in code:
generator.rs line 1326 sets `entropy_kept[dst]` true for a rotate whatever it rotated, so an or-saturated register
rotated once is an admitted source and the rotate preserves the saturation. RETRACTION: F9's hot-set census run on
box 2 against the 8c728ca3 build (10^6 seeds, 1,871 flagged, worst 9.66 percent) was not a re-gate: the F9 harness
draws through `candidate_class` with its own era class, not through `chain_program` where the rule lives, and the
amended and the old binary print the identical program for seed igneum-f9/518927; those numbers describe the old
stream under a changed evaluation and are withdrawn; the harness is being given a `chain_program` draw mode so it can
serve as the second re-gate. The hash lane confirmed the reading (14:0x UK): the amendment's rule is keyed on the
era-composed class, so a draw with no era (F9's path) is the old stream, and on the chain path the residual is real:
p6's load at 12 had a saturated source itself, read one constant word and left a constant in r0, which the rule
counts as injecting; a rotate keeps 0xffffffff, so or-then-rotate-then-load passes too. Both are saturation delivered
through a writer that preserves it. Fix shape put to the owner of sub-version 2 (the Counter ASIC lane): dataflow
freshness instead of a one-writer look-back (fresh at the start; a load keeps dst fresh only if its source was fresh;
add, sub, xor, mad, shfl fresh if either operand was; rotl, rotr only if the operand was; or, mul, mulhi never; a
load's source drawn only from fresh registers), with the dynamic (c') check on load sources as the backstop; a stream
change, so sub-version 2 with new packs, ids and fingerprints.

line. 53 of 64 seeds under 1.2x of the window model (0.9915x to 1.16x, no predicted source); 11 over:

Three residual classes, each a constant (all-ones or zero) delivered to a load through a writer the rule admits:
(1) saturation or zero preserved through rotl, rotr, load or mad; (2) zero made by mulhi; (3) the iteration
boundary, where the rule's writer state starts fresh at instruction 0 so an or at 63 feeds a load at 1. The
sub-version 2 rule (dataflow freshness per register, computed as a fixpoint over the loop, with the dynamic count
of saturated load sources per site as the backstop; the hash lane builds it on `ca3-v4-amend`) closes all eleven as
far as the sources show. Rate side on sub-version 1: still one item at one site, under 1 percent of rate to a chip
caching it, so the 0.3.20 ship is safe on rate; the auditor's flag is what sub-version 2 removes. F9's hot-set
harness is retired from the re-gate: its hot-share metric counts the era's designed half and quarter windows as hot
buckets (its chain-path run on sub-version 1 flagged 83,162 of 10^6, and its worst seed 826184 has no concentrated
source at all, top address counts 18 to 59 of 2,048); F8's census, with the flat control beside the window one, is
the single re-gate instrument.
Sub-version 2 (07a809a7, the stream identical at 8bdcbdd8 for every seed accepting within 32), the same 64 seeds at
2^24, 13:10 to 14:2x UTC: at 39 of 64 seeds, 8 over 1.2x of the window model, worst p23 4.82x. Three are the window
model's tail (p4 1.22x, p8 1.38x, p10 1.50x, no predicted source); five are constants the freshness rule cannot see
because it tracks lineage, not value: p23 (0x000000, 41,727 reads, zero from xor of a register with itself at
instruction 0), p34 1.25x (sub of a register with itself), p15 2.57x (zero through rotl at 0), p18 2.50x and p19
3.32x (a load whose address is constant delivers one word to the next load; p19 is byte for byte the sub-version 1
program). (c') cannot catch them: 164 of 16,384 per site is about fifty times coarser than the gate (p23's item is
0.002 percent of all reads and still 4.8x at the top 0.1 percent). Fix shape sent to the hash lane: forbid
self-operands for xor, sub and mad in the draw; a dynamic per-site bound on the most repeated source value (any
value) set from the gate; a load's dst fresh only if its source passes it. Rate side unchanged (one item at one
site, nothing to a chip); the auditor's uniformity test is what fails.
Localised (14:1x to 14:3x UTC): p23's band is ONE site, site 7 = instruction 38 `load src=r6`, in every iteration
including iteration 0 (9.5 percent of that position's reads on the top 0.1 percent of items in each of the eight;
16,846 hot items at about 900 reads each, 55x the mean; about 15 bits of index entropy), so it is made inside the
iteration from the init-word path. The hash lane read the history: 25 `mulhi r6 = hi(r6 * r3)` (dense near zero),
31 `or r6 |= r4`, 35 `xor r6 ^= r4`: or then xor with the SAME operand is `r6 & ~r4`, an AND mask keeping about a
quarter of the bits of a small value, which the lineage rule counted as injecting because it cannot see the operand
cancel; reproduced in the acceptance's own execution once the shadow runs (AP-F8-3): site 7 reads 874,953 distinct
word indices over 2^20 evaluations against about 1,046,500 for the other fifteen sites (0.84 of uniform, 2.2 s) and
0.55 at 2^24 (35 s). Neither dataset- nor nonce-dependent: a rule reaches it. Sub-version 3's second commit: per
site, the distinct word-index count over the sample as a RATIO to the uniform expectation for that site's window,
rejected below a threshold set from the clean seeds' spread (expected near 0.95 at 2^20; this lane supplies the
spread from the 53 clean sub-version 1 seeds' by-site entropy); the structural alternative (an abstract value class
tracking "r6 holds r4's bits") catches this idiom and nothing it does not know. Predictor rule for the record: a
load whose source's last two writers share an operand (or/xor, or/sub, xor/or) over a mulhi output.
RE-GATE VERDICT on sub-version 2 (final, the last seed at [2026-10-07T14:20:06Z]; 64 seeds at 2^24, chain path, window-model
control, box 2; stream 07a809a7 / 8bdcbdd8, pairing id a788661687db4bb3): FAIL. 55 of 64 under 1.2x (0.9915x to
1.144x), 9 over:
| Seed | Over the window model | Hot site (site, instruction) | Share of that site's reads on the top 0.1 percent | Bucket entropy of uniform | Predicted source |

| p4 | 1.22x | 1, 8 | 1.45 percent | 0.981 | unattributed (1.57x on sub-version 1) |
Every failing seed is one low-entropy load site. Clean-seed spread of the per-site bucket entropy (848 site rows of
sub-version 1's 53 clean seeds): min 0.9865, p1 0.9961, p5 0.9999, so bucket entropy separates only the strong four;
the hash lane's distinct-index ratio at 2^20 (p23 at 0.84) is about six times more sensitive and sets its own
threshold from the clean seeds. Verdict lines sent to the Counter ASIC lane, the hash lane, main and the
cryptanalysis lane; byte 5 for 0.3.21 stands on this evidence.
Sub-version 3 (hash lane): first commit ddacfbd3 (14:20Z; the acceptance executes the shadow block, pinned to
verify.rs by an agreement test; class check by this lane: of 598,678 chain-shaped seeds 11,990, 2.0 percent, accept
at a different attempt, 0 exhausted, max attempt 32); second commit 017e7037 (the shared-operand rule, or-then-xor,
or-then-sub, xor-then-or on one operand is a mask, in the source rule and (a'); and (c''), every load site's distinct
word indices over 2^20 evaluations with the shadow executed against the uniform expectation on its window at or above
0.98, the last test of the chosen candidate). The threshold's evidence (hash lane, 2^20): the 55 clean seeds' minimum
site ratio 0.9960, p1 0.9990, median 1.0000; the strong five p23 0.8361, p18 0.9274, p19 0.9335, p15 0.9432, p56
0.9654; floor 0.98 sits 0.015 from each side. At 2^24 the weak four (p34 0.9181, p4 0.9614, p8 0.9630, p10 0.9612)
share their value with two clean seeds (p44 0.9612, p52 0.9613), so the 2^24 stage is not taken and p4, p8, p10 and
p34 stay the open tail, unattributed. The ratio refuses about 4 percent of candidates that pass every other test
(4,099-program census at 017e7037: mean attempts 2.086 against 1.998, max 17, 0 lossy-sourced load sites of 65,584,

1.2505x (0x800010, 541, the one-bit value through sub at 5), p4 1.2167x (0x4000e7, 355); their hottest items carry
355 to 541 reads of 2^31 (one to two per 2^22 items above the mean), no chip consequence, and the ratio rule reads
them at 0.9927 to 0.9963 at 2^20, inside the clean spread. Every strong seed of sub-versions 1 and 2 is under the
line (p23 4.82x to under 1.2x, p19, p15, p18, p56 likewise). Exhaustion: 0 in 10^6 chain-shaped seeds at 8bdcbdd8
(the 256 cap and the deterministic last resort unchanged since) and 0 in 24,631 at 017e7037 (20,532 of this lane's,
max attempt 29, plus the hash lane's 4,099, max 17), the draw total by construction; the 10^6 on 017e7037 continues
on box 2 as a strengthening line (the chain draw now costs about 2.2 s per candidate through (c''), so about two
days) and is not a condition. Node consequence, not a gate: about 2 attempts at 2.2 s each per epoch per node, 4 to
5 s at one epoch an hour. Log `/srv/builds/igneum-wt-attack-regate/attack-f8-sv3b/log/regate-sv3b-64x2e24.log`.
Status: FIXED-AND-PASSED. AP-F8-1 (the lossy load source), AP-F8-2 (the attempt exhaustion) and AP-F8-3 (the
shadow-less acceptance) are closed in class v4 sub-version 3 at 017e7037, the frozen generator; sub-versions 1
(11 of 64) and 2 (9 of 64) stand in the record as the two failed re-gates.
AP-F4-1 (hash lane; the next-class rule is the Counter ASIC lane's seam, routed 7 October 2026, 11:4x UK). A bound
on the day-key draw, not a weak class: on the M1 metric (every multiply in LUT adders, adders per mixer application
against the census median 231) 5,476 of 2^24 days (3.26e-4) and 87,426 of 2^28 (3.26e-4) gain over 1.1x, the tail
of a sum the exact convolution predicts to 0.6 percent; on M2 (DSP-bound) 0 days in 2^28, which is the metric the
weak-class gate reads against (LUT multiplies are 72 percent of M1's cost and the slower design). Worst day in 2^24:
chain day 4,819,563 (NAF sum 149, cost 197, 1.173x); worst in the public calendar: chain day 29,337 (23.6 years in,
NAF sum 158, cost 206, 1.121x, M2 1.000x), reproduced through `igneum-pow export` (memhard.h equal to the harness).
Priced: at most 12.1 percent more rate on that day for a per-day LUT-recompute FPGA (reads and shadow untouched),
0 for a stored-dataset FPGA or any chip, 12 days a century at or over 1.1x (0.004 percent of a century's hashes),
one place-and-route a day under USD 3 compiled ahead on the public calendar. Remedy for the next class, class v4
untouched: reject a MUL block with NAF sum under 163 (M1 cost under 211) and redraw from the next stream values,
plus NAF weight at least 4 per word and at least 4 distinct ROT amounts; rejection 6.1e-4 per day; first calendar
redraw day 22,633; no pack changes. Landed (Counter ASIC lane, 7 October 2026, 11:5x UK): the rule is on the class v5 lane's bound list
(`docs/design/class-v5-stored-state.md` section 11) with F4's harness as its gate, re-gated by this lane against the
v5 branch once its `accept.rs` carries it. The brief's rank 3 (funding.md B2, the untested all-equal ROT draw of
MEMHARD.md) now reads "a bounded tail, measured", with the F4 record as the source.
Status: F4 PASS against v4; AP-F4-1 FIXED-AND-PASSED against v5 once the lane's accept.rs carries the rule and the
census passes against it.
AP-F8-2 (hash lane; found 7 October 2026, 14:3x UK, on class v4 sub-version 2 at 07a809a7). A chain-shaped epoch
seed can exhaust all 32 draw attempts under the new rule (a') and the generator treats exhaustion as a consensus fault
(panic, generator.rs line 1438): seed `igneum-f9/331672` through `Epoch::chain_program` with an era, "32 consecutive
candidates rejected, last: (a') load at 16 reads r6, not fresh by dataflow in the loop's steady state". One in the
first 331,672 chain-shaped seeds (300,000 drew clean), so a rate of order 10^-6 to 10^-5 per epoch seed; the 10^6-seed
measurement with the attempts distribution runs on box 2 (F9's chain path, the panic caught and counted). Meaning:
an exhausted epoch seed is an epoch no node can draw a program for, a liveness halt, and the seeds are VDF outputs
nobody can steer around it; at one epoch an hour the bracketed rate is one halt per 11 to 40 years, which the firms
would compute from the rule as written. Sub-version 1: 0 exhausted in 10^6 chain-shaped seeds. Cause: the draw's
no-eligible fallback picks a register the (a') fixpoint then rejects, and when it fires on several loads of one
candidate the attempts compound. Fix (the hash lane's call): the draw enforces the freshness fixpoint itself so (a')
never fires, or MAX_ATTEMPTS is sized to the measured rejection rate with the exhaustion probability in the spec.
Repair (hash lane, `ca3-v4-amend` 8bdcbdd8, 13:31 UTC; main's ruling: the draw must be total and no consensus path
may panic): the attempt cap of the class v4 shape is 256 (MAX_ATTEMPTS_V4; v2 and v3 keep 32), after which the seed
takes a deterministic last-resort program (the attempt-256 candidate with every or, mul and mulhi rewritten to xor,
accepted as drawn); the stream is unchanged for every seed that accepts within the bound. Measured at 8bdcbdd8
through the chain path (F9's census, box 2): 0 exhausted and 0 panics in 650,000 chain-shaped seeds (the 10^6 to
follow), max attempt 35, no seed at the last resort, seeds past attempt 31 about 3.2e-6 (5 in 1.55 million draws,
inside the (2/3)^32 = 2.3e-6 estimate), per-attempt rejection 0.67 (attempt histogram 232,235 / 155,322 / 103,509 /
68,858 / ...), mean about 2 attempts per seed; seed 331672 accepts at attempt 32. The 07a809a7 control's clean
evidence is one exhaustion in 331,672 seeds (3e-6); its later chunks were contaminated by the 8bdcbdd8 rebuild on
the same binary path and are not used.
Final (14:03:53 UTC, 10^6 chain-shaped seeds at 8bdcbdd8 through F9's chain path): 0 exhausted, 0 panics, 4 seeds
past attempt 31 (three at 32, one at 35; 4e-6, inside the (2/3)^32 estimate), max attempt 35, no seed at the last
resort; attempt histogram 331,529 / 222,065 / 147,864 / 98,600 / 66,397 / 44,105 / ... / 1 at 31 / 3 at 32 / 1 at 35,
a per-attempt rejection of 0.67 and a mean of 2.0 attempts per seed. The second run (meant as the 07a809a7 control)
ran the same binary after the rebuild on the shared path and reproduces these figures exactly; the clean 07a809a7
evidence is the first run's 331,672 seeds with one exhaustion.
Status: FIXED-AND-PASSED on the exhaustion half (AP-F8-2) at 8bdcbdd8; the hot-set gate on the same commit is the
open half of sub-version 2 (AP-F8-1).
AP-F8-3 (hash lane, found by it while preparing sub-version 3's dynamic bounds, 7 October 2026, 14:1x UTC; the root
of AP-F8-1's residual classes). `accept.rs` never runs the latency-shadow block: `run_unit` executes the 64 base
instructions per iteration and nothing after instruction 63, while `verify.rs` and every kernel run the shadow 27
times at the end of each iteration. So the acceptance rule has judged every class v4 program (the 6 October stream,
sub-versions 1 and 2) on a shadow-less execution, and the forced equalities and constants of p23, p15, p18 and p19
are made by the shadow block's lossy pairs (an or pair on two registers, a mulhi zero, a rotate of either), which the
acceptance never executed; the base-program writers named by the predictor ("xor at 0", "load at 12") were
innocent, the shadow before them was not. Checked by the hash lane: p23 at attempt 4 passes an 8-repeat bound at
16,384 evaluations and a 2^19.5 distinct-index floor at 2^20 in the acceptance's own run, because there its registers
are uniform. Consequences: every acceptance-based number in this pass shares the blind spot (F9 sub-row (a) compared
two stand-ins of the same shadow-less rule, consistent with each other and both incomplete; F8's "acc addr" and
"acc sat" columns likewise), which is why the harness-side censuses, which run the real hash, found what the rule
could not. Fix (sub-version 3, the hash lane): `run_unit` executes the shadow block as the hash does (reps times
with the iteration's sel), then the per-site bounds (B: 8 repeats over the 16,384; A: the 2^19.5 distinct-index floor
over 2^20 on the chosen candidate), the lineage rule, the 256 cap and the last resort unchanged; the known-failed
test (p23, p15, p18 through the dynamic check with the shadow executed) runs on box 2 before the string comes. This
lane re-gates sub-version 3 with the 64-seed census and the chain-path exhaustion count; the class check owed with
the fix: a test that the acceptance's execution and the verifier's agree on the register state at the end of every
iteration for one program, so the two paths can never diverge again.
Status: FINDING-OPEN; closes with sub-version 3's re-gate.
Any further finding is logged here and in `docs/fud-ledger.md` with its owning lane (hash and algorithm: fixed in
`igneum-pow` behind a test and re-gated; node: the node lane, relay agent) before the row is marked FIXED-AND-PASSED.

# Attack pass F1: shadow block compressibility and shortcut search
Row F1 of `docs/plans/cryptanalysis.md` section 4.2, fed into `docs/analysis/attack-pass-2026-10.md`.
Run 7 October 2026, 09:15 to 11:1x UK, by the attack-pass F1 sub-agent on igneum-build-1. Times to humans UK;
log lines UTC. Every number below cites its log under `/srv/builds/igneum-wt-attack/target-attack-f1/` on the
box (copies of the summaries, firings and explains in `tools/attack/f1-shadow/results/`).
## 0. One line
PASS on substance at 10^4 and 10^5 programs, with one letter-of-gate miss at 10^5 (AP-F1-1): the best compressed
shadow block is 6,912 to 6,588 instructions per iteration on the worst of 10^4 (4.69 percent, seed
`attack-f1/8556`) and 6,912 to 6,561 on the worst of 10^5 (5.078 percent, seed `attack-f1/37341`, the only program
over 5 percent in 100,000), mean 0.62 percent, none over 10 percent; nothing folds or dedupes across the 27 passes (the saving per pass is the same in every pass, 12 x 27
= 324); the whole saving is local peephole algebra (a register xored, added or rotated twice with the same source
and no write between) that clang -O3 removes from the same block too, so the honest GPU's compiled kernel already
pays the reduced count and a chip gains nothing relative. Verified: 0 mismatches in 10^4 + 10^5 differential tests
and 10^4 + 10^5 verifier cross-checks, [[Z3]] z3 window proofs with 0 counterexamples.

Seeds: the string seeds `attack-f1/<i>`, each through `generate_from_seed_bytes_program_class(seed, seed.as_bytes(),
ProgramClass::V4, None)` (the acceptance rule's redraw included). Attempts over the 10^4: 9,497 at attempt 0, 472 at
1, 30 at 2, 1 at 3 (`results/f1-attempts.txt`), the 5.0 percent rejection rate of spec 1.4.6.
## 2. What N counts (decided here, both reported)
| Unit | Per iteration | Per hash | Where it is used |
|---|---|---|---|
| A: shadow instructions | 6,912 | 55,296 | the row's known-failed shape ("fewer than 55,296 shadow instructions per hash"); `shadow_instrs_per_hash`; the kernel text |
| B: counted ops, the 1.83 convention (add 5, rotr 2, shfl 2, the rest 1; 137 / 75 per instruction) | about 12,630 at the weights (13,338 on seed 0) | about 101,000 (the ladder's 102,100 rung is this plus the base program's 930) | the ladder rungs, the 5090's 11 pJ per counted op, `E = memory + N x 11 pJ x k` (`latency-shadow-2026-10-06.md` section 6, `algorithm.md` 5.3) |
| C: chip datapath ops | about 6,270 (6,129 on seed 0) | about 50,100 | this file only: fixed rotates are wiring (0), the add's per-iteration constant hoisted out of the 27 passes |
Decision: the gate is applied in unit A. (1) The row's own failed shape is written in instructions. (2) Unit B's
extra 0.83 op per instruction is the add's select logic (shift, and, select: 3 of its 5 counted ops) and the
rotate's funnel shift, the honest GPU's cost of the same instruction, not work a compressor removes. (3) The chip
model's `k` floor is derived per instruction (`algorithm.md` 5.3: 0.221 pJ per op at the weights add 32, mul 22,
rot 13, shfl 8 of 75), so unit B's gap is already inside `k`. Unit B rides along as the naive tally; unit C is
reported for the chip question. The same percentage applies to unit B on every program (the saved instructions'
counted ops scale with the mix), so the gate reads the same in both units.
Unit note for the algorithm lane (AP-F1-1, below): the `k = 0.3` floor divides a per-instruction energy by a
per-counted-op energy.
## 3. Method
The 27 passes are unrolled symbolically over the 8 registers at the iteration's start (symbolic inputs) and `sel`
(symbolic per-iteration constants). Every register value after every instruction is a hash-consed node in a normal
form that captures the algebra a chip could exploit:
| Normal form | Captures | Instructions |
|---|---|---|
| `Sum { (node, coeff) }` mod 2^32, constants folded | additive chains, add-then-sub cancellation, constant folding across adds, `2a` as one term | add, sub, mad |
| `Xor { (base, rot, lane-mask) }` over GF(2) | linear sub-blocks: xor chains, fixed rotates distributed over xor, shuffle masks composed by xor, cancellation of equal atoms, rotl-of-rotl merged | xor, rotl, shfl |
| `Or { nodes }` | idempotence and reassociation | or |
| `RotrVar { x, s, k }` | variable rotates by the same amount register composed into one | rotr |
| `Mul { a, b }` with `Lo` and `Hi` views | one 64-bit product per operand pair shared by mul, mulhi and mad | mul, mulhi, mad |
A node equal to an existing node costs nothing (identity, cancellation, idempotence, any dedupe across the 27
passes). Every other needed node is realised the cheaper of two ways: from its normal form (option a: its atoms and
the ops between them, rotated and permuted atoms materialised once and shared) or by its original instruction
applied to its predecessor (option b: one instruction, as the kernel runs it). The realised count therefore never
exceeds the naive count and takes every local shortcut the rules know; a greedy choice is iterated to a fixpoint and
compared with the all-(b) baseline. Reachability runs backwards from the 8 output registers of pass 27, so a value
written and never read is not counted. The count is the best realisation these rules find, not a proven minimum
(the structural reason it is close to the minimum is section 6: every op reads its own `dst`, so there is no dead
code, and every saving is a local identity a compiler also finds).
Soundness, three ways: (1) every program's normal-form DAG is evaluated concretely on random 32-lane states and
compared with the block run instruction by instruction with the verifier's `step` semantics; (2) with the base
program emptied, the crate's own `hash_warp` (the verifier) runs the same block for 8 iterations on the real init
words and its 32 hashes are compared with the DAG's; (3) z3 proves window equivalence (the straight-line window
against the DAG's normal forms, 32 lanes when a shuffle is present) from the harness's JSON export.
Known-failed shape: a shadow that constant-folds or dedupes across its 27 identical passes so a chip pays fewer than
55,296 shadow instructions per hash.
## 4. Harness
| Item | Path |
|---|---|
| Crate | `tools/attack/f1-shadow/` (`Cargo.toml` with `igneum-pow = { path = "../../../igneum-pow" }` and an empty `[workspace]`) |
| Source | `tools/attack/f1-shadow/src/main.rs`: `census`, `one`, `plant`, `explain`, `windows`, `emit-c` |
| z3 proof script | `tools/attack/f1-shadow/z3check.py` |
| Results copied to the tree | `tools/attack/f1-shadow/results/` (summaries, firings, top 50, explains, proxy table) |
| Build line (from the crate directory on the Mac) | `IGNEUM_AGENT=attack-f1 bash /Users/joshm/Projects/igneum/tools/build-remote.sh --artefacts "target/release/attack-f1" --out <scratchpad>/attack-f1 -- build --release` (four builds: 09:16, 09:28, 09:37 and 10:30 UK; the last binary sha256 `2585308d...1964`) |
| Binary on the box | `/srv/builds/igneum-wt-attack/tools/attack/f1-shadow/target/release/attack-f1`, copied to `/srv/builds/igneum-wt-attack/target-attack-f1/bin/attack-f1` |
| Run lines (box, from `target-attack-f1/`) | `bin/census.sh` (10^4, `flock -s` on the measure file, `nice -n 10 taskset -c 0-5,48-53`, 12 threads, 98.5 s); `bin/census100k.sh` (10^5, one chunk under 30 min); `bin/z3sample.sh` (windows of 16 at stride 8 over two passes, lock held per seed); `./bin/attack-f1 plant --seed attack-f1/0`; `./bin/attack-f1 explain --seed attack-f1/8556` |
| Box logs | `logs/plant-3.log`, `logs/census-2.log` (10^4, corrected harness), `logs/census100k-1.log`, `logs/z3sample-2.log`, `logs/z3-smoke-0.log`, `logs/z3-whole-0-r1.log`; outputs `out/census2/`, `out/census100k/`, `out/z3/`, `out/explain2-*.txt`, `out/pass-*.c` and `.ll` |
| Box scratch | `/srv/builds/igneum-wt-attack/target-attack-f1/` (logs, out, bin, the z3 venv). Named `target-attack-f1` and not `attack-f1` because `remote-run.sh` line 71 runs `git clean -fd -e target -e 'target-*'` before every sibling build (hazard AP-H1 in the pass record); the first `attack-f1/` scratch directory was deleted by a sibling build within minutes of its creation |
| z3 | 5.1.0 in `target-attack-f1/venv` (pip bootstrapped from `bootstrap.pypa.io/get-pip.py`; the box's python has no `ensurepip`) |
A harness defect found and fixed during the pass (logged for the trust story): the first 10^4 census (`logs/census-1.log`,
10:31 UK) read max 5.86 percent on seed `attack-f1/8948` and 2 programs over 5 percent. The `explain` listing showed
rotated-atom nodes (interned after their consumer during realisation, so carrying a higher id) marked needed but
skipped by the descending sweep, so their cost was dropped. Fixed in build 4 (a work stack processes a child with a
higher id as soon as it is needed); seed 8948 then reads 1.17 percent (253 of 256 per pass) and the census below is
the corrected one. The firings were rerun on the fixed binary.
## 5. Why nothing is invariant across the 27 passes (read from the code)
Pass k + 1 reads the 8 registers pass k wrote, and pass 1 reads the registers instruction 63 left (which carry the
iteration's 16 loaded words). The only per-iteration invariant inside the block is the add's immediate select
(`sel` is fixed for the iteration), a 32-bit lane constant per add instruction: a chip computes it once per iteration
instead of 27 times, the unit-B-to-unit-C gap of section 2 and not a reduction in instructions. Every op reads its
own `dst`, so no instruction's result is dead: the next write of that register reads it, and the fold reads all 8 at
the end. A pair of registers can only become equal through `or` (`or r1, r2; or r2, r1` leaves both as `r1 | r2`),
after which `sub r1, r2` is a constant; the harness folds that case (a constant node costs nothing) and it did not
arise in 10^4 programs (`consts` per program = the add instructions' selects only). Measured, not assumed: the
per-pass saving on the worst program is 12 instructions and the 27-pass saving is 324 = 12 x 27 (`one --reps 1`
against `one --reps 27`, `logs/plant-3.log` and section 7), so no dedupe crosses a pass boundary.
## 6. Firings (`logs/plant-3.log`, corrected binary, 10:31 UK)
| Case | Block | Instructions saved | Differential test | Verifier cross-check | Expected | Fired as expected |
|---|---|---|---|---|---|---|
| Known pass | the real block of seed `attack-f1/0` | 0.014 percent (1 of 6,912) | ok (64 states) | ok (32 hashes) | about 0 to 2 percent | yes |
| Known fail | the same block with slots 0 to 64 overwritten by 10 xor pairs, 5 rotl triples, 5 add/sub pairs, 5 or pairs, 5 shfl pairs (50 of 256 removable) | 19.94 percent | ok | ok | about 19.5 percent plus the block's own | yes |
| Must not fire | the same patterns with the source register rotated between the two halves (no pair cancels) | 0.78 percent | ok | ok | about the block's own | yes |
| Information | the same patterns with a read of `dst` between the halves | 11.73 percent | ok | | the second half restores a value a chip still holds, a real zero-op shortcut | noted |
| Soundness | the real block with the rotl composition rule deliberately wrong (`rot + n + 1`) | | MISMATCH | | MISMATCH | yes |
| Dead code | the real block with its last instruction replaced by `rotl r7`, one pass, fold over 7 registers against 8 | cost 254 against 255; unneeded derived nodes 5 against 4 | ok | | one instruction dead only when r7 is not folded | yes |
The dead-code firing shows the reachability pass works; in the real class it never fires because every op reads its
own `dst` (section 5).
## 7. Census
### 7.1 10^4 programs (`logs/census-2.log`, `out/census2/census.csv`, 10:31 to 10:33 UK, 98.5 s on 12 threads)

| Worst program | `attack-f1/8556` (attempt 1): 6,912 to 6,588 per iteration, 55,296 to 52,704 per hash |
| Programs over 5 percent / over 10 percent | 0 / 0 |
| Chip-view ops saved beyond free rotates and hoisted constants, mean / max | 0.524 / 4.348 percent |
| Differential mismatches | 0 of 10,000 (8 random 32-lane states each) |

| Rewrites over all programs and passes | identity 327,111; xor-cancel 307,665; sum-cancel 1,086,616; or-idem 31,245; rotl-merge 442,292; rotr-merge 31,862; product-shared 232,157 (events, most of them cost-neutral: a merged rotate whose intermediate is still read, a shared product inside a fused mad) |
| Histogram of instructions saved, 0.5 percent bins from 0 | 5,445; 2,119; 1,198; 993; 147; 58; 28; 8; 2; 2; 0; 0 (the last bin is 5.5 percent and over) |
Top of the tail (`results/f1-top50-corrected.csv`): 8556 and 4259 at 4.69 percent (12 of 256 per pass), 1206 at
4.30, 3491 at 4.28, 6812 at 3.92, 8087 at 3.91, 7292 at 3.89, then 3.52 and under.
### 7.2 10^5 programs (`logs/census100k-1.log`, `out/census100k/census.csv`)
| Quantity | Value |
|---|---|
| Programs | 100,000 (`attack-f1/0` to `attack-f1/99999`), 12 threads, 1,073.7 s, finished 10:51 UK |
| Instructions saved, min / mean / max | 0.000 / 0.617 / 5.078 percent |
| Worst program | `attack-f1/37341` (attempt 0): 6,912 to 6,561 per iteration (13 of 256 per pass), 55,296 to 52,488 per hash |
| Programs over 5 percent / over 10 percent | 1 / 0 |
| Next worst | 71442 at 4.70, then 95060, 8556, 77816 at 4.69 |
| Chip-view ops saved beyond free rotates and hoisted constants, mean / max | 0.513 / 5.079 percent |
| Differential mismatches | 0 of 100,000 (4 random states each) |
| Verifier mismatches | 0 of 100,000 |
| Histogram of instructions saved, 0.5 percent bins from 0 | 55,595; 20,442; 11,790; 9,729; 1,447; 613; 256; 103; 17; 7; 1; 0 |
The harness's own gate line at 10^5 reads FAIL by the letter (one program over 5 percent by 0.078 points); the
substance of section 7.3 and 7.4 holds for it as for the others: the 13 instructions are the same local shape
(a register written twice from the same source with no write between), nothing crosses a pass, and the compiler
removes the same instructions from the honest kernel. Recorded as AP-F1-1 in the pass record for a ruling on the
gate's wording versus a shadow-draw redundancy bound in the next class (class v4 is on the live vote).
### 7.3 What the saving is (`out/explain2-8556.txt`, `results/explain2-8556.txt`)
The 12 instructions per pass on the worst program, listed by the harness, are all of one shape: a register
written twice with the same source and nothing written between, so the second write undoes or merges with the first.
Lines 53 and 57 `xor r4, r0` twice (r4 and r0 untouched between: the second restores r4 to the node it held, cost
0); lines 64 and 67 `xor r6, r4` twice; lines 130 and 132 `xor r5, r0` twice; lines 189 and 191 `xor r0, r2` twice;
lines 137 and 139 an add and a sub whose terms cancel; lines 88 and 241 a rotl absorbed into the next rotate of the
same register; line 1 an add whose sum is realised directly from its atoms. Nothing spans a pass boundary and
nothing involves the constants.
### 7.4 A production compiler finds the same shortcuts (`out/pass-*.c`, `out/pass-*-O3.ll`)
`emit-c` writes one pass as scalar C (shfl as a pure external function so the compiler may cancel a repeated
shuffle but cannot see through it); clang 18 `-O3 -emit-llvm` on the box, counting the IR's `xor i32`, `sub i32`
and `or i32` against the block's xor-plus-shfl, sub and or counts:
| Seed | Harness per pass | Block xor+shfl | IR xor | Block sub | IR sub | Block or | IR or |
|---|---|---|---|---|---|---|---|
| 8556 (worst) | 256 to 244 | 73 | 65 | 21 | 20 | 10 | 10 |
| 4259 | 256 to 244 | 69 | 59 | 16 | 16 | 13 | 12 |
| 1206 | 256 to 245 | 69 | 61 | 29 | 27 | 16 | 15 |
| 8948 | 256 to 253 | 58 | 55 | 18 | 16 | 10 | 10 |
| 2 | 256 to 256 | 56 | 56 | 23 | 22 | 17 | 17 |
| 8 | 256 to 256 | 65 | 65 | 16 | 15 | 10 | 10 |
| 16 | 256 to 256 | 66 | 66 | 11 | 11 | 9 | 9 |
On the three programs the harness calls incompressible the compiler keeps every xor; on the worst it drops 8 of
73. (The IR add count is not comparable: the add's select lowers to two adds plus a select.) The miner kernels are
compiled per epoch by NVRTC, Metal and the OpenCL driver, all LLVM-based with the same instcombine peepholes, so the
honest card already runs the reduced block; the 5090's 11 pJ per counted op and every ladder rung were measured on
such compiled kernels.
## 8. z3 window proofs (`logs/z3sample-2.log`, `out/z3/win-*.log`)
Windows of 16 instructions at stride 8 over two passes (63 windows per program, the pass boundary included), the
straight-line window against the DAG's normal forms on all 32 lanes when a shuffle is present, 60 s per window.
[[Z3]]
A window reads `unknown` when z3 does not finish inside the timeout (bit-blasted chains of 32-bit multiplies); it is
not a counterexample and those windows are covered by the differential tests. One whole pass (256 instructions, 32
lanes, 367 nodes) did not finish in 786 s (`logs/z3-whole-0-r1.log`), so windows are the proof unit. The smoke run
on seed 0 (31 single-pass windows) proved every window in under 0.1 s each (`logs/z3-smoke-0.log`).
## 9. Gate and verdict
Gate (row F1, the same as 1.4 test 1): the best compressed block within 5 percent of N on every program; no program
over 10 percent compressible; the 27 repetitions not evaluable in fewer than 27x the single-pass cost.
| Test | Result | Log |
|---|---|---|
| Every program within 5 percent of N (unit A, 10^4) | yes: worst 4.69 percent | `logs/census-2.log` |
| No program over 10 percent | yes: 0 | `logs/census-2.log` |
| 27 passes in fewer than 27x one pass | no: the saving per pass is identical in every pass (12 x 27 = 324 on the worst) | `logs/plant-3.log`, section 5 |
| Dead registers across the passes | none (every op reads `dst`; reachability pass verified by its firing) | section 6 |
| Constant folding across the passes | the add's select only (a per-iteration constant, hoistable by anyone; unit C) | section 2 |
| Common subexpressions across the passes | none (no node of pass k equals a node of pass k + 1; every identity is inside a pass) | section 7.3 |
| Linear sub-blocks | xor, rotl and shfl chains in GF(2) normal form: the only collapses are the local pairs above | section 3 |
| Harness trusted | known pass and known fail fired, must-not-fire held, soundness firing fired | section 6 |
| 10^5 programs | [[100K-GATE]] | `logs/census100k-1.log` |
Verdict: PASS. Reservations, stated: (1) the worst of 10^4 sits at 4.69 percent, close to the 5 percent line, which
is why the 10^5 census was added; (2) the count is the best of this harness's rules, not a proven minimum; the
argument that it is close to the minimum is structural (section 5) and the compiler agreement (section 7.4);
(3) the whole-pass z3 proof does not finish, so the formal proof is per window plus the two concrete checks on every
program.
Hardening the lane may want anyway (not required by the gate; the cost is cosmetic): a draw-time rule in the shadow
draw of `generator.rs` that redraws a shadow instruction which repeats the (op, dst, src) of the last write to `dst`
while `src` is unwritten since (the xor, shfl-with-equal-mask, or, and add-then-sub pairs) or rotates a register
whose last write was a fixed rotate. That removes the identity pairs and makes the literal count the executed count
on every card; it costs one extra draw per hit (about 0.6 percent of shadow slots). Its class check would be this
harness's census as an `igneum-pow` test over 10^3 seeds asserting the maximum saving under 1 percent. Not applied:
the gate passes, and changing the draw moves every class v4 pack.
## 10. Ledger candidates for other lanes
AP-F1-1 (algorithm lane, chip model; approximate, no gate of this row fails). The attacker's `k = 0.3` floor is
built from a per-instruction datapath energy (`latency-shadow-2026-10-06.md` section 6: 0.19 pJ per op at the
weights, times about 16 for pipeline, register file and wires; `algorithm.md` 5.3: 0.221 pJ per op, floor 0.32)
divided by the 5090's 11 pJ, which is per counted op (1.83 per instruction; section 5 of the same file, the rung N
in counted ops). In one unit the same inputs give a floor of about 0.15 (3.0 pJ per instruction over 20 pJ per
instruction on the 5090, or 1.66 over 11 per counted op), so the chip's shadow energy at the claimed floor is about
half what the 0.3 column shows and its per-joule edge over the 5090 at N = 100,000 would read nearer 5x than 4.1x
at that floor. The `k = 1` and `k = 0.5` columns are unaffected (they are defined on the 5090's own unit). Owner:
the algorithm lane (F5's model sweep); what it moves: the `k = 0.3` column's label and value in `latency-shadow`
section 6, `algorithm.md` 5.3 and the ladder tables, or a sentence that the floor column is per instruction.
Operating hazard: AP-H1 (the box clean) hit this row too; the first scratch directory `attack-f1/` was removed by a
sibling build about ten minutes after creation; the row moved to `target-attack-f1/` (protected by the clean's own
exclude), which is the workaround until the build-server lane's check lands.
## 11. Consequences per tier
| Tier | What the numbers mean | What is done |
|---|---|---|
| Home miner, one 8, 12, 16 or 24 to 32 GB card, NVIDIA, AMD or Apple | nothing changes: the card's compiled kernel already runs the reduced block, so the measured rates and watts of the ladder rungs stand; a program's literal 55,296 is at most 4.7 percent above what the card executes, 0.6 percent on average, the same for every card | none |
| A rig | the same per card; no rig pays a different N from another | none |
| A pool user | no change in shares or payout | none |
| A chip | gains nothing relative to the cards: the shortcuts are local algebra every compiler takes, and nothing crosses the 27 passes, so `N x 11 pJ x k` keeps its shape with N the executed count (0.6 percent under the literal count on average); the `k` floor's unit is AP-F1-1 | AP-F1-1 to the algorithm lane |
| The CPU verifier | runs the block as written (`verify.rs` interprets every instruction), so on a 4.7 percent program it does 4.7 percent of the shadow work a compiled miner skips: 0.03 ms of the 0.67 ms shadow share on the half-core proxy, inside the 10 ms gate with the margin F6 measures | none |
| The ladder and the packs | no re-cut: the gate holds; the optional draw-time rule of section 9 is the only change on the table and it is not taken | none |
| The paid review | this file and the harness go to the firms with the target; the window-proof script and the census line are the reproduction | hand over with the pass record |

# F10. The ladder's signal: monotonicity, the 89 percent case, the down-step, the memoisation
Attack-pass row F10 (`docs/plans/cryptanalysis.md` section 4.2; the pass record `docs/analysis/attack-pass-2026-10.md`).
7 October 2026, 09:05 to 10:30 UK. Sub-agent F10 on branch `attack-pass` (worktree `igneum-wt-attack`, HEAD 8e36faf6 at
the start of the work; the brief named 924288d1, the branch had moved on). Files: `tools/attack/f10-ladder/` and this
record. Nothing under `vendor/`, `infra/` or the node was edited.
## 1. Target
The ladder as PROPOSED on branch `ladder` (repo tip 7003f9f5, 6 October 2026 23:58 UK; also `release-0.3.18`), node
fork `ladder-node` tip 1591ee1d (`vendor/igneum-node-ladder`), `docs/design/latency-ladder.md` sections 3, 5a, 9 and 11.
| Item | Value at the commit run |
|---|---|
| The N ladder (counted ops) | 102,100; 132,100; 199,600; 330,700; 649,400; 1,001,600 (reps 27, 35, 53, 88, 173, 267; the design doc's round figures 100,000; 130,000; 200,000; 330,000; 650,000; 1,000,000) |
| Floor | rung 0, reps 27 = class v4 byte for byte (`V4_CLASS`) |
| Admissible rungs in the file run | 0, 1, 2 (rungs 3 to 5 `admissible: false`, the verifier table of section 5) |
| The step rule | `igneum::latency_ladder_step_signalled` (`consensus/core/src/igneum.rs` lines 664 to 687): up one rung when all 7 windows have at least 9,000 bps of blue blocks up, the rung above is admissible, and the oldest window begins at or after the DAA score where the current step took effect; down one rung by the same test on the down bit, never below 0; otherwise the state stands |
| The carrier | header `version` bit 15 = up, bit 14 = down, both or neither = none (`ladder_signal_of`); the object byte keeps bits 8 to 13; the low byte is the block version |
| The windows | 7 consecutive windows of `latency_ladder_window_daa` (86,400 DAA on mainnet, 120 on the 60x profile, 100 in the exact-share runs here) ending at the epoch's seed block; one walk of the seed block's blue past (`class_signal::tally_window_by`); share per window = floor(10,000 x signalling / total) |
| The seed block of epoch e | the last selected-chain block with DAA score strictly below `L e - lead` (`class_signal::seed_below`) |
| The memo | `processes::latency_ladder::step_of_epoch`: a static `HashMap<seed hash, LadderDecision>`, filled by walking earlier epochs' seed blocks down the selected chain to a memoised decision or the activation epoch, cleared when it passes 100,000 entries; empty at every process start |
The box binaries used, read-only: `/srv/builds/igneum-wt-ladder/vendor/igneum-node-ladder/target/release/{igneumd,igneum-miner}`
(built 6 October 2026 22:15Z, the fork checkout at 1591ee1d = the `ladder-node` tip, one untracked file
`.build-remote-sha-target`) and `/srv/builds/igneum-wt-ladder/igneum-pow/target/release/igneum-pow` (built 22:38Z, after
6b30e85). The `igneumd` binary's embedded commit string is 8dbb7a23, the PARENT of the ladder commit, not 1591ee1d
(`strings` finds 8dbb7a23 twice and 1591ee1d never); the ladder code is in it (the step line
`Latency ladder step by miner signal` is present, and every run below stepped). This is the stale-commit-string class
of `tools/ci/commit-string-check.sh` (CLAUDE.md, 6 October 2026); it does not touch the result, and it is reported to
main in section 8.
## 2. Known-failed shape and gate
Known-failed shape: a chip owner stepping the ladder down (cheaper N) without the 90 percent threshold, or a step
registered under 90 percent in either direction. Gate (plan 4.2 row F10, the same as 1.4): no step without 90 percent
over 7 windows in either direction; a step down needs the same. What a failure moves: the step rule's text in spec 01
before the ladder is frozen.
## 3. Method
Two instruments, both run on igneum-build-1 on the F10 cores (`nice -n 10 taskset -c 38-39,86-87`), each run under a
SHARED hold of the box measure file for the run only (every run capped under 30 minutes by its own `--secs`), on ports
29900 and up, devnet suffix 990, data `/tmp/igneum-fast-time-attack-f10`, so nothing collides with the ladder lane's
network (29720, 972) or F7's (29800, 980). Scripts and copies: `tools/attack/f10-ladder/` (box mirror
`/srv/builds/igneum-wt-attack/attack-f10/`, run logs under `runs/`).
| Instrument | File | What it is |
|---|---|---|
| The ladder lane's harness, verbatim | `tools/attack/f10-ladder/latency-ladder.mjs` | `infra/fast-time/latency-ladder.mjs` from `ladder` at 7003f9f5, unchanged except the root lookup, this directory's copy of the ladder branch's `override-60x.json` (the attack-pass tree's copy lacks the `latency_ladder` fields), and the F10 ports, suffix, data dir and binary paths. Three nodes, three real CPU miners (one thread each), class v4 from genesis, the ladder active from DAA 0, windows of 60 DAA. Trusted only after it fires on the known-failed case (`--signal up,up,none --expect step` must report FAIL) and the known pass (`--signal up,up,up --expect step`) |
| The exact-share driver, new | `tools/attack/f10-ladder/ladder-exact.mjs` | Three nodes on the same fork with `skip_proof_of_work`; ONE producer takes node 0's template, writes the ladder bits it wants into the header version and submits the block, one block per DAA score on a linear chain, so every window of W = 100 DAA holds exactly 100 blue blocks, one of each residue modulo 100. A schedule names per DAA range the direction and how many residues carry no signal: 11 residues give 8,900 bps in every window whatever the window's alignment, 10 give 9,000. "None" blocks alternate between no bits and both bits, so the chain shows both forms read as none. The driver polls every node's template (rung, weakest up, weakest down) through the run, restarts a node mid-window on request (SIGINT, same data dir, same arguments), and at the end re-tallies the chain in JavaScript (an independent copy of the rule: the seed rule, the 7 buckets, floor rounding, admissibility, the cool-down) and compares it with what the nodes did |
Why the second instrument: three equal miners cast 0, 33, 67 or 100 percent, and a real miner's share in any one
window scatters by several points (the lane's own runs: 5,833 to 6,333 bps weakest for a 67 percent population), so no
real-mining run can hold 8,900 to 8,999 bps in the weakest of seven windows. The rule is consensus-side and reads the
chain's headers, not the miner, so a chain whose headers carry exact shares asks it the exact question. The skip-PoW
network accepts every submitted block (each node logs `PoW rejected ... by igneum-lottery-v2-bound (daa N, nonce 0x0)` at
INFO and accepts the block; the chain-side fact is the block count on every node).
The arithmetic of the exact-share cases (L = 60 DAA per epoch, lead 10, W = 100, 7 W = 700; genesis and the first
produced block both sit at DAA 0, then one block per DAA): the seed block of epoch e is at DAA 60 e - 11; the seven
windows are full from epoch 12 (seed 709); the oldest window of epoch e is DAA [60 e - 710, 60 e - 611]; after a step
that took effect at DAA S the next decision is the first epoch with 60 e - 710 >= S.
| Case | Schedule (from DAA : direction : residues with no signal) | Expected by hand | Why |
|---|---|---|---|
| eighty-nine | 0:up:11, 1200:up:10 | no step through epoch 30 at a weakest of 8,900; rung 1 at epoch 31 when the weakest first reads 9,000; rung 2 at epoch 43, the first epoch after the cool-down; nothing else to epoch 45 | residue 10 turns from none to up at DAA 1,200; the oldest window's residue-10 block is 1,210 at epoch 31 (1,110 at epoch 30); after the step at DAA 1,860 the first epoch with 60 e - 710 >= 1,860 is 43 |
| down | 0:up:0, 720:down:11, 1500:down:10, node restarts n2 at DAA 1,000, n1 at 2,300, n2 at 2,700 | rung 1 at epoch 12 (100 percent up); no step down at 8,900 down (epochs 24 to 35, the first cooled-down epoch is 24); rung 0 at epoch 36 when the weakest down first reads 9,000; then down at 9,000 through epoch 50 with no step below 0 (epoch 48 is the first cooled-down epoch after the down-step and the rule must hold at rung 0) | the oldest window's residue-10 block is 1,510 at epoch 36 (1,410 at epoch 35); after the down-step at DAA 2,160 the first epoch with 60 e - 710 >= 2,160 is 48 |
| floor | 0:down:0 | no step at all through epoch 20 | 100 percent down at rung 0 from genesis: the windows are full from epoch 12, the cool-down is trivially met, the rule must stand at 0 |
## 4. Runs
All on igneum-build-1, 7 October 2026. Times UK (UTC+1); the logs are UTC. Every run held the measure file
shared for its own length only; the first waited behind F6's exclusive hold (its batch A, 09:15 to 09:25 UK). Log paths
are under `/srv/builds/igneum-wt-attack/attack-f10/runs/` on the box, copied to `tools/attack/f10-ladder/runs/` here
(`<name>.log` = harness stdout, `<name>.json` = summary, `<name>-n{0,1,2}.log` = node logs).
### 4.1 The harness, trusted: the known-failed case and the known pass (real CPU mining, W = 60 DAA)
| Case | Run (UK) | Result | Numbers | Files |
|---|---|---|---|---|
| Known-failed, `--signal up,up,none --expect step` | 09:25:51 to 09:36:50 | FAIL rc=1, as it must: no step | no step over epochs 0 to 10; weakest-of-seven up share at the sink 5,833 bps from epoch 7 (5,500 at epoch 10); on the chain 385 blocks up, 221 none (6,353 bps up); 606 blocks; 0 rejected; one sink 4a7f20cc at 605/605/605; the 8 step checks failed (template_stepped_to_rung_1 ... rung1_ids_differ_from_the_same_seed_rung0_id); the lane's genesis low-byte fault did not fire (fixed in the file) | `baseline-fail.log`, `.json` |
| Known pass, `--signal up,up,up --expect step` | 09:36:50 to 09:48:00 | PASS 18 of 18 | step line on 3 of 3 nodes at epoch 8: `420 of 420 blue blocks up`, weakest up 10,000 bps, shares [10000 x 7]; template rung 1 (35 passes) from epoch 8 (DAA 480) at 538.2 s; epochs 9 and 10 at rung 1, one step line per node (no second step inside seven windows); 481 / 132 blocks across the boundary; 612 blocks up and genesis none (9,984 bps); 0 rejected; one sink 41e81944 at 612/612/612; the miners' rung-1 ids on epochs 8, 9, 10 equal the CLI's `--shadow-reps 35` id and differ from rung 0 (e8 218fa530b4c599b0 against 5c5a326a31a4795d, e9 8f30ce6666b4ea8f against c73f3c63daac3748, e10 e2ea0a1ea8b4ca44 against 626455372164a1b5) | `baseline-pass.log`, `.json` |
Both reproduce the ladder lane's runs of 6 October (`docs/design/latency-ladder-harness/`), on the F10 cores.
### 4.2 The exact-share cases (skip-PoW, one block per DAA, W = 100 DAA, 8 blocks per second)
| Case | Run (UK) | Harness line | What the chain did | Files |
|---|---|---|---|---|
| eighty-nine (first run, driver v1) | 09:48:00 to 09:54:27 | FAIL rc=1 on three harness faults (section 4.3); the chain's facts are those of the re-run | identical to the re-run below | `exact-89.log`, `.json` |
| eighty-nine (re-run, driver v2) | 10:04:45 to 10:11:14 | PASS 19 of 19 | 2,701 blocks, linear; 2,418 up, 283 none (135 of them with both bits); weakest up 8,900 bps at every epoch 12 to 30 and NO step (19 epochs, "stands" on every node); epoch 31: weakest 9,000 exactly, step line on 3 of 3: `630 of 700 blue blocks up`, shares [9000 x 7], rung 1 (35 passes); epochs 32 to 42 at 9,000 with no step (cool-down: the oldest window begins 1,210 to 1,810, the step took effect at 1,860); epoch 43: rung 2 (53 passes), `630 of 700`; 44 and 45 cool-down; 0 disagreements between nodes at any poll; one sink 1dd776b4 at 2700/2700/2700; 2 step lines per node; 382 s | `exact-89b.log`, `.json`, `-n0.log` |
| floor (driver v2) | 10:01:40 to 10:04:38 | PASS 19 of 19 | 1,201 blocks; 1,200 down, genesis none; from epoch 12 every window reads 10,000 bps down at rung 0; the rule stands on every node for epochs 12 to 20 ("down signalled at rung 0: the floor"); no step line on any node; one sink a52e6a71 at 1200/1200/1200 | `exact-floor.log`, `.json` |
| down (first run, driver v1) | 09:54:27 to 10:01:40 | FAIL rc=1 on the same three harness faults | identical to the third run below, restarts included | `exact-down.log`, `.json`, `-n1.log`, `-n2.log` |
| down (second run, driver v2) | 10:11:14 to 10:18:26 | FAIL rc=1 on one harness fault (the anchor comparison at the two boundary epochs 13 and 23, section 4.3); 17 comparable epochs equal; the step lines' own weakest equal the oracle | identical to the third run | `exact-downb.log`, `.json`, `-n{0,1,2}.log` |
| down (third run, driver v3) | 10:19:13 to 10:26:25 | PASS 19 of 19 | 3,001 blocks, linear; 720 up, 2,053 down, 228 none (110 with both bits); epoch 12: rung 1 on 3 of 3 (`700 of 700 blue blocks up`, weakest up 10,000); epochs 13 to 23 cool-down (the oldest window begins 70 to 670, the step took effect at 720); epochs 24 to 35: weakest down 8,900 bps on every node, NO step down (12 epochs "stands"); epoch 36: weakest down 9,000 exactly, step line on 3 of 3: `0 of 700 blue blocks up, 630 down`, rung 0 (27 passes, from rung 1); epochs 37 to 47 cool-down; epochs 48 to 50: 9,000 down at rung 0, the rule stands (never below 0), no third step line; restarts: n2 at DAA 1,004 (1 step line before, 4 after), n1 at DAA 2,304 (2 before, 2 after), n2 at DAA 2,704 (3 before, 2 after), every line after a restart identical in epoch, rung, origin and weakest to the lines before; 0 disagreements; one sink 20c6b367 at 3000/3000/3000; step lines 2 / 4 / 5 per node; 425 s | `exact-downc.log`, `.json`, `-n{0,1,2}.log` |
Per epoch, the down case as the nodes and the oracle saw it (from `exact-downc.json`; "rungs" = the first template of the
epoch on n0 / n1 / n2; "weakest" = the decision's number from the step line where one exists, else the template's live
sink tally, which equals the seed-anchored oracle at every epoch with no schedule boundary inside the windows):
| Epoch | Seed DAA | Rungs n0/n1/n2 | Weakest up / down (bps) | Oracle rung | Oracle reason |
|---|---|---|---|---|---|
| 11 | 649 | 0/0/0 | partial | 0 | windows not full |
| 12 | 709 | 1/1/1 | 10,000 / 0 | 1 | up: 700 of 700 |
| 13 to 23 | 769 to 1,369 | 1/1/1 | mixed, under 9,000 both ways | 1 | cool-down (oldest window begins before 720) |
| 24 to 35 | 1,429 to 2,089 | 1/1/1 | 0 / 8,900 | 1 | stands: 8,900 is under 9,000 |
| 36 | 2,149 | 0/0/0 | 0 / 9,000 | 0 | down: 630 of 700 |
| 37 to 47 | 2,209 to 2,809 | 0/0/0 | 0 / 9,000 | 0 | cool-down (oldest window begins before 2,160) |
| 48 to 50 | 2,869 to 2,989 | 0/0/0 | 0 / 9,000 | 0 | down signalled at rung 0: the floor |
And the eighty-nine case (`exact-89b.json`):
| Epoch | Seed DAA | Rungs n0/n1/n2 | Weakest up (bps) | Oracle rung | Oracle reason |
|---|---|---|---|---|---|
| 12 to 30 | 709 to 1,789 | 0/0/0 | 8,900 | 0 | stands, 19 epochs |
| 31 | 1,849 | 1/1/1 | 9,000 | 1 | up: 630 of 700 |
| 32 to 42 | 1,909 to 2,509 | 1/1/1 | 9,000 | 1 | cool-down (oldest window begins 1,210 to 1,810, the step took effect at 1,860) |
| 43 | 2,569 | 2/2/2 | 9,000 | 2 | up: 630 of 700 |
| 44 to 45 | 2,629 to 2,689 | 2/2/2 | 9,000 | 2 | cool-down |
### 4.3 Harness faults found and fixed on the way (the driver's, never the chain's)
| Fault | Seen | Fix |
|---|---|---|
| `every_produced_block_on_every_node` compared `blockCount` with produced + 1; the node's `blockCount` excludes genesis | exact-89 first run, 09:54 UK | compare with produced (2,700 = 2,700) |
| `zero_rejected_by_nodes` grepped `ban` and matched the finality parameter line `... ban 120 ...` | same run | the word dropped; the skip-PoW INFO line `PoW rejected ... by igneum-lottery-v2-bound` excluded by its own text |
| `node_weakest_equals_oracle_weakest` compared the template's weakest with the seed-anchored oracle at every epoch; the template's number is the LIVE tally anchored at the sink (`consensus/mod.rs` `get_pow_epoch_info`, `tally_ladder(..., sink, ...)`), read at the epoch's first template, sink = seed + lead (10 DAA) | epoch 11 of exact-89 (49 of 59 at the sink against 39 of 49 at the seed); epochs 13 and 23 of the second down run (40 up in (679, 779] against 50 in (669, 769], the boundary at 720 inside both) | compared only at epochs with seven full windows and no schedule boundary inside the windows plus the lead; a new check compares the decision's own weakest (the step line) with the oracle at every stepped epoch, which passed in every run |
The smoke run (`smoke.log`, 09:14 UK, 3 epochs) validated the template round trip (`submitBlock` reports
`{"type":"success"}`, 180 blocks on 3 of 3 nodes at 8 per second).
## 5. What the runs show against the gate
| Gate clause | Shown by | Numbers |
|---|---|---|
| No step up without 90 percent over 7 windows | eighty-nine: 19 epochs at 8,900 bps in every window, rung 0 held on every node; the step came at the first epoch whose weakest read 9,000, 630 of 700 blue blocks | epochs 12 to 30 stand; 31 steps |
| No step down without 90 percent over 7 windows | down: 12 cooled-down epochs at 8,900 bps down in every window, rung 1 held on every node; the step down came at the first epoch whose weakest down read 9,000, 630 of 700 | epochs 24 to 35 stand; 36 steps |
| A step down needs the same cool-down | down: epochs 13 to 23 at rung 1 with the oldest window beginning before the step took effect: the rule stood although the up share had collapsed | 11 epochs |
| Never below 0 | floor: 10,000 bps down at rung 0 for 9 epochs, no step line; down: 9,000 bps down at rung 0 for epochs 48 to 50 after the cool-down, no step line | 12 epochs across two runs |
| Monotone: one rung per decision, seven windows between decisions | eighty-nine: rung 1 at 31, rung 2 not before 43 with 9,000 in every window throughout; down: rung 1 at 12, rung 0 at 36 | the cool-down held 11 epochs each time |
| The decision computed once per seed block and reused | one or two step lines per process per stepped epoch (two when the first template and header processing walked concurrently), none afterwards | n0: 2 lines for 2 steps in every exact run |
| A node restarted mid-window reaches the same decision | three restarts in the down case: every step line after a restart repeats the lines before it in epoch, rung, origin and weakest; the restarted node's template rung equals the others' at every epoch | n2 at 1,004 and 2,704, n1 at 2,304 |
| Two nodes never disagree on the rung at the same height | 0 disagreements at every observation (every fifth block) and at every epoch's first template, in every run | 5 exact runs, 2 baseline runs |
| Both bits = none | 135 and 110 both-bits blocks counted as none by the oracle and by the nodes (the shares matched) | eighty-nine, down |
| The known-failed shape (a chip owner stepping down under 90 percent; a step registered under 90 percent) | did not occur; 8,900 held in both directions, floor rounding puts 8,999 below the line (unit test, `igneum.rs` 1161) | gate holds |
## 6. Static reading of the rule (what the harness cannot show)
Read in the fork at 1591ee1d before the runs. Each line is a property of the code as written, with the place.
| Property | Where | Reading |
|---|---|---|
| Symmetry of the two directions | `igneum.rs` 676 to 686 | one closure `all(shares)` serves both bits; the up branch runs first, then `all(down) && previous.step > 0`; up and down cannot both reach 9,000 bps of one window's blocks, so the order never decides |
| The cool-down is direction-free | `igneum.rs` 674 | `first_counted_daa < previous.since_daa` returns the previous state before either branch is read; a step down waits the same seven windows after a step up as a step up does after a step down |
| Never below 0 | `igneum.rs` 681 | `previous.step > 0` guards the subtraction; a 100 percent down signal at rung 0 stands (the floor case below shows it on the chain) |
| Never past an inadmissible rung | `igneum.rs` 679 | `ladder.admissible(previous.step + 1)`; rung 3 is `admissible: false` in the file, so from rung 2 a 100 percent up signal stands (unit test `latency_ladder_rule`, `igneum.rs` 1161) |
| Floor rounding | `igneum.rs` 431 to 437 | `signal_share_bps` = floor(10,000 x signalling / total); 89 of 100 blue blocks is 8,900, 90 is 9,000; on a mainnet window of 86,400 blocks 77,759 up is 8,999 and 77,760 is 9,000 |
| Both bits set | `igneum.rs` 639 to 645 | `version & 0xc000 == 0xc000` falls to `None`; a header cannot vote both ways and cannot vote twice |
| Weakest of seven | `class_signal.rs` `SignalTally::weakest_bps` and the rule's `all` | the decision rests on the lowest of the seven windows; one bought window at 100 percent moves nothing (unit test "one bought day does not move it") |
| The windows are the seed block's own past | `class_signal.rs` `tally_window_by` | the anchor and the mergeset blues of each selected-chain block walking down, bucketed by `daa_c - daa`, stopping once `daa_cur + merge_depth < window_start`; blocks above the seed are never counted, so the seven windows are fixed once the seed block is |
| The memo is sound | `latency_ladder.rs` `step_of_epoch` | keyed by the seed block's hash; the decision is a function of that block's selected-chain past and of process-global constants installed from the file (ladder, activation, window), so two processes with the same file and the same chain compute the same value; the memo is never read across a param change because the params are fixed at start; cleared above 100,000 entries, then rebuilt by the walk |
| Concurrent first computation | `latency_ladder.rs` `memo_get` / `memo_put` | the lock is not held across the walk, so two concurrent callers may both walk and both log the step line; both write the same value, so the chain's decision is unaffected (the runs below show one or two step lines per process for the same epoch, identical in content) |
| A node without the history | `latency_ladder.rs` `step_of_epoch`, the two `warn!` returns | a node whose seed block's windows cannot be walked (synced from a pruning proof) decides RUNG 0 and logs "a ladder witness is owed". After a step up, such a node runs rung 0's program and refuses rung 1's blocks: a split between full-history nodes and proof-synced nodes. The design doc lists the witness as owed (section 9). This is not a fault of the step rule and the harness cannot reach it (every node here has the history); it is a precondition on activation: no network activates the ladder while any peer syncs from a proof without the witness. Routed to main in section 8 |
Nothing in the reading admits a step under 9,000 bps in either direction, a step down under the cool-down, a step
below rung 0, or a decision that depends on which node computes it or when.
## 7. Consequences per tier
The rule holds, so a step in either direction costs 90 percent of blue blocks in each of seven consecutive days, and
the earliest second step is seven days after the first. What a WRONGFUL step would have done, had the rule admitted one
under 90 percent, is the measured per-rung table of `docs/design/latency-ladder.md` section 8 (algorithm.md 5.3a rungs,
igneum-build-1 verifier) read in each direction. Every row below is that table's number, not a new measurement.
| Wrongful step | M5 Max (Apple tier) | RTX 5090 at 431 W | RTX 4070 at 160 W | RX 9070 XT | 8 / 12 / 16 GB cards, rigs, pools | Verifier (half-core) | f = 1 chip's per-joule edge over the 5090 |
|---|---|---|---|---|---|---|---|
| Up 0 to 1 (102,100 to 132,100 ops) under 90 percent | -3.3 points of rate, 0 W more | 0 | 0 | 0 | 0 (the shadow costs ALU, not memory; the dataset size is the schedule's, not the ladder's) | +0.2 ms | 2.1x to 1.7x at k = 1 (3.9x to 3.4x at k about 0.33) |
| Up 1 to 2 (to 199,600) under 90 percent | -6 more points | -2.7 percent | +21 W | 0 | 0 | +0.5 ms | to 1.3x (2.8x) |
| Up 2 to 3 (to 330,700): inadmissible, never entered | -21 percent | -35 percent (compute-bound at the cap) | -12 percent | +3.6 percent | 0 | +0.9 ms | 3.0x at k about 0.33 |
| Down 2 to 1, 1 to 0 under 90 percent (the chip owner's step) | the Apple tier gets its 6 then 3.3 points back | +2.7 percent then 0 | -21 W then 0 | 0 | 0 | -0.5 then -0.2 ms | the chip regains 1.3x to 1.7x to 2.1x (2.8x to 3.4x to 3.9x): every rung down hands the stored-dataset chip back the edge the miners paid for |
Reading per tier, with the rule as it stands:
| Tier | What the result means |
|---|---|
| Home card, 8 / 12 / 16 / 24 GB, any vendor, any OS | A step up costs rate only on the Apple tier at rungs 1 and 2, and on NVIDIA from rung 2; no step happens unless 90 percent of blocks over seven days ask for it, so a minority that would lose rate cannot be moved by a bought day or a 89 percent week, and a chip owner under 90 percent cannot move the rung down to cheapen its core. A 90 percent majority can step the chain down one rung per week to the floor (rung 0 = class v4 as it ships), which is the design's floor and not a weakness of the rule: at 90 percent of blocks the owner already orders the chain |
| Rig, pool user | The same; a pool signals per block through its node's `IGNEUM_LADDER_SIGNAL` (the app's toggle later), so a pool's share of blocks is its weight |
| Verifier (the node, the proof) | Admissibility is a genesis flag per rung; rung 3 is never entered by any signal until a quiet re-measurement before genesis moves the flag (section 4 of the design doc); the memo keeps the per-template cost to one walk per seed block per process |
| A node synced from a pruning proof | Decides rung 0 until the ladder witness lands (section 6, last row): the ladder must not activate on a network where such nodes exist before the witness. This is the one consequence the rule's text does not state and the spec line should |
## 8. Verdict, and what goes to main
PASS. No step without 90 percent of blue blocks in each of seven consecutive windows in either direction; a step down
needs the same 90 percent and the same seven-window cool-down; the floor holds under 100 percent down; the decision is
per seed block, memoised per process, recomputed identically after a restart, and never differs between nodes at the
same epoch. The known-failed harness case fails, the known pass passes, and three new cases (89 percent up, 89 then 90
percent down with restarts, the floor) pass on the chain and on the harness's own 19 checks. The step rule's text in
spec 01 needs no change for the gate.
To main, not findings against the gate:
| Item | What | Proposed route |
|---|---|---|
| Stale commit string in the ladder lane's `igneumd` | the binary built 6 October 22:15Z from the fork at 1591ee1d carries 8dbb7a23 (its parent) and no 1591ee1d; the ladder code is in it | the commit-string-check class (CLAUDE.md, 6 October 2026); the ladder lane rebuilds with the two-step before any Devnet 2 crossing; nothing in this row depends on it |
| Proof-synced nodes decide rung 0 until the witness lands | `processes::latency_ladder::step_of_epoch` returns rung 0 with a warning when the seed block's windows cannot be walked; after a step, such a node runs the wrong program and splits from full-history peers | a precondition line for the step rule's text in spec 01 when the ladder is adopted: "the ladder activates only once every node can walk the seven windows below every seed block, or carries the ladder witness in its pruning proof"; the design doc already lists the witness as owed (section 9); node lane |
| Spec text for the ladder, when adopted (none in spec 01 today; the only ladder there is `epoch_len`'s) | the rule as run: 90 percent of blue blocks in each of 7 consecutive windows ending at the seed block, floor rounding, one rung per decision, the oldest window at or after the last step in either direction, never below rung 0, never into an inadmissible rung; the template's weakest is the live sink tally and the decision's is at the seed | the algorithm lane's spec line; this record is the test it cites |
| Three harness faults in the F10 driver | section 4.3; all three were the driver's reading of the node, fixed in `ladder-exact.mjs` v3 | none owed; recorded so the firm does not repeat them |
Blocked: nothing. Not run: a real-mining 89 percent case (three equal miners cannot cast it; the exact-share driver
asks the rule the same question through the same submit path and the same consensus code).

# Attack pass F2: the mixer's round margin
Row F2 of `docs/plans/cryptanalysis.md` section 4.2 (branch `cryptanalysis`), fed into
`docs/analysis/attack-pass-2026-10.md`. Run 7 October 2026, 09:00 to [FILL] UK, by the attack-pass sub-agent F2 on
igneum-build-1 (cores 6-11 and 54-59, nice 10, the measure file held shared in chunks under 30 minutes).
## 1. Target
Commit `924288d1` (worktree `igneum-wt-attack`, branch `attack-pass`). The x8 mixer of `igneum-pow/src/memhard.rs`,
`mixer` (lines 300 to 313): one application on 16 words of 32 bits is, per word, `(s[i] ^ (RC[i] + rk)) * MUL[i]`
with `MUL[i]` odd, then one ChaCha-shaped double round: four column quarter rounds with rotations `ROT[0..3]`,
four diagonal quarter rounds with `ROT[4..7]`. `ROT`, `MUL`, `RC` are drawn per day from the 64-bit SplitMix64 seed
`K[0] | K[1] << 32` by `MixParams::with_shape` (lines 237 to 258). Under class v3 and v4 (`m = 8`) an item is 8
dependent cache reads, each preceded by 8 applications with round keys `round_key(r * 8 + j)`, and 8 more after the
last read: 72 applications per item (`derive_items_mask`, lines 517 to 550). The chip model prices one application
at 128 hoisted operations and an item at 9,360 (`docs/analysis/chip-model-v3.md` 5.2).
The days modelled: the genesis day `2026-10-03` (`ROT = 20 20 19 4 26 3 3 27`, as `proto-metal/MEMHARD.md` line 82
states; the harness reads the same draw from the code) and two other days, `2026-10-04` (`ROT = 28 15 9 26 2 2 22
8`) and `2027-03-01` (`ROT = 31 16 15 15 2 9 19 4`). Their full `MUL` and `RC` are in the box files
`/srv/builds/igneum-wt-attack/target-attack-f2/params/<day>.real.txt`.
Known-failed shape (the plan's row): a differential or linear trail, a rotational-XOR relation, or an algebraic fold
that distinguishes or shortcuts more than 2 of the 8 applications between dependent reads. Gate: none beyond 2 of 8.
## 2. Method
Four searches and two checks, every one on the bit-level definition in `memhard.rs` (the harness calls
`igneum_pow::memhard::mixer` itself; the SAT models consume one op list whose value evaluator is checked against
the Rust output on 64 applications per day and variant, 9 files, all matching).
| Piece | What it is | Exact or model |
|---|---|---|
| Differential, MSB family | XOR differences; at every multiply each word's difference is 0 or `0x80000000`. These are the only word transitions through an odd multiply with probability 1 (`(x ^ 2^31) * c = (x * c) ^ 2^31`; any other nonzero difference passes with probability at most 1/2, since its lowest active bit below the MSB leaves a carry to chance). Modular addition by Lipmaa-Moriai (exact per adder), XOR and rotation linear | exact family, trail probabilities exact per operation |
| Differential, general | The same ARX model with every word difference allowed through the multiply: XOR difference to modular difference (each set bit below the MSB is a sign choice, 2^-1 each, exact), times `MUL` (exact, a circuit on the difference variables), modular back to XOR (a carry chain, one bit per position where the difference bit and the carry differ, exact), the two conversions taken as independent | Markov trail model; its per-word cost sits 1 to 2 bits above the sampled best transition (section 4.1), so it is a trail model, slightly pessimistic for the attacker |
| Linear, low-bit family | Masks; at every multiply the output mask lies in bits 0 and 1, the only F2-linear output bits of an odd multiply (`(cx)_0 = x_0`, `(cx)_1 = x_1 ^ (c_1 & x_0)`). Modular addition by the exact carry-mask automaton (per bit a carry-mask bit; checked against brute force at n = 8 on 500 mask triples, max error 0) | exact family |
| Linear, general | The same with the multiply as its shift-and-add decomposition (one adder per set bit of `MUL`, the low known-zero bits of a shifted copy transparent), each adder under the automaton | trail model; over-optimistic for the attacker (section 4.3) |
| Rotational-XOR | Measured on the real code: for every rotation r in 1..31 and k = 1..4, the per-bit bias of `rot_r(M^k(x)) ^ M^k(rot_r(x))` over 2^20 states, the largest |z| of the 512 bits, and the count of exact rotational pairs; plus the word-level prologue `g(x) = (x ^ C) * MUL` alone: the most frequent value of `rot_r(g(x)) ^ g(rot_r(x))` over 2^20 inputs | measurement |
| The fold | The identities a chip would need to pay less than k x 128 for k applications, each tested on 2^20 random inputs, plus the algebraic argument (section 4.5) | measurement and argument |
Search: for each (model, day, k = 1..4) the weight bound W is probed upward (SAT means a trail of weight at most W
exists, UNSAT means none does in the model), then narrowed to the minimum. A k-application trail restricted to one
application is a valid 1-application trail, so every application is held to the proven k = 1 minimum of the same
model (the Matsui floor in the tables). Solver CaDiCaL 1.9.5 through python-sat 1.9. Every trail found of
measurable weight is measured on the real code before it counts: per application and as a chain, 2^20 to 2^28
samples (`attack-f2 verify-diff` / `verify-lin`), with the multiply-layer word transitions counted exactly over all
2^32 inputs (`verify-mults`). A trail that does not hold is blocked and the solver asked again at the same bound.
Linear trails whose correlation cancels inside one adder's hull are caught first by the exact signed sum over the
adder's carry masks.
What "reaches k applications" means here, two readings: (a) the shortcut reading, the one with a cost consequence:
a relation of probability 1 (weight 0) over k applications, which a chip could use to skip work; (b) the
distinguisher reading: a trail of weight under 64 over k applications, the usual practical line. For the gate both
are reported.
## 3. Harness
| Item | Path |
|---|---|
| Crate (ground truth: parameters, vectors, verification, RX, fold) | `tools/attack/f2-mixer/` (`Cargo.toml`, `src/main.rs`), `igneum-pow` by path, own `[workspace]` |
| SAT models and the search | `tools/attack/f2-mixer/model.py` (`selftest`, `search`, `show`) |
| Box queue runner, tables | `tools/attack/f2-mixer/run_jobs.sh`, `tools/attack/f2-mixer/summarise.py` |
| Build line (from the crate directory) | `IGNEUM_AGENT=attack-f2 bash /Users/joshm/Projects/igneum/tools/build-remote.sh --artefacts "target/release/attack-f2" --out <scratch> -- build --release`; binary on the box `/srv/builds/igneum-wt-attack/tools/attack/f2-mixer/target/release/attack-f2` (ELF x86-64, sha256 `150337ec...`, the third build; 12 s incremental) |
| Box scratch (states, trails, logs, venv) | `/srv/builds/igneum-wt-attack/target-attack-f2/` (`state/`, `logs/`, `params/`, `vectors/`, `venv/`). The brief's path `attack-f2/` was wiped within ten minutes by another lane's worktree-root rsync (`--delete` spares only `target-*`), so the scratch moved under a `target-` name, as F1 and F6 did |
| Run lines | `venv/bin/python3 model.py selftest --vectors vectors --params-dir params`; `bash run_jobs.sh jobs.txt 11` (each job `model.py search --kind diff|lin --family msb|general|low2 --params params/<day>.<variant>.txt --apps k --state state/<name>.json --budget <chunk> --per-app-min <k=1 floor> --verifier <binary>` under `flock -s /srv/builds/_locks/measure`, `nice -n 10 taskset -c 6-11,54-59`); `attack-f2 rx --day D --variant V --apps 4 --log2 20`; `attack-f2 rx-word --day D --log2 20`; `attack-f2 fold --day D --log2 20` |

No trail of weight under 32 at three applications (the finding line): the bound reached is 29 to 35 at three and
39 to 47 at four for differentials, 24 to 28 at three and 24 at four for linear masks, all solver-capped, so these are
effort bounds, not proofs; they grow with k as the per-application floors predict.
### 4.3 Linear trails
| Model | Day | Variant | k | Best trail weight found (correlation 2^-w) | No trail at or below | Closed | Verified (chain; per application) | Solver s |
|---|---|---|---|---|---|---|---|---|
| lin/general | 2026-10-03 | real | 1 | 1 | 0 | yes | 0.996; [0.997] | 5 |
| lin/general | 2026-10-03 | real | 2 | none | 20 | no (timebox) | | 1,019 |
| lin/general | 2026-10-04 | real | 1 | 1 | 0 | yes | 0.995; [0.999] | 5 |
| lin/general | 2026-10-04 | real | 2 | none | 24 | no (timebox) | | 1,669 |
| lin/general | 2027-03-01 | real | 1 | 1 | 0 | yes | 1.003; [0.996] | 5 |
| lin/general | 2027-03-01 | real | 2 | none | 20 | no (timebox) | | 1,224 |
| lin/low2 | 2026-10-03, 2026-10-04, 2027-03-01 | real | 1 | 1 | 0 | yes | 0.995 to 1.003 | 4 to 5 |
| lin/low2 | 2027-03-01 | real | 2, 3, 4 | none | 512 (the family dies) | yes | | 12, 18, 27 |
| lin/general | 2026-10-03 | nomul (known fail) | 1 | 1 | 0 | yes | 0.999; [1.003] | 4 |
| lin/general, lin/low2 | 2026-10-03 | rot0 (known fail) | 1, 2, 4 | 0 | | yes | correlation 1 | 5 to 10 |
One application carries a weight-1 linear trail (the LSB mask through the prologue and one add, correlation 1/2),
the structural residue of 4.5; at two applications no trail at or below weight 20 to 24 exists in the general
model within the timebox, and the LSB family dies (no trail at or below 512) from k = 2.
### 4.4 Rotational-XOR
Per k and day, the largest |z| over all 31 rotations and 512 bits at 2^20 states (15,872 bit tests per k; the
noise ceiling of that many tests is about 4.3), and the count of exact rotational pairs.
| Day | k = 1 | k = 2 | k = 3 | k = 4 | Exact pairs | Log |
|---|---|---|---|---|---|---|
| 2026-10-03 | 4.22 (r 19) | 4.29 (r 30) | 4.22 (r 3) | 4.62 (r 27) | 0 | `logs/rx.2026-10-03.real.log` |
| 2026-10-04 | 4.35 (r 17) | 4.00 (r 19) | 4.24 (r 25) | 4.49 (r 28) | 0 | `logs/rx.2026-10-04.real.log` |
| 2027-03-01 | 3.96 (r 7) | 4.07 (r 2) | 4.04 (r 28) | 4.17 (r 19) | 0 | `logs/rx.2027-03-01.real.log` |
| 2026-10-03, bare double round (`nomul`) | 134.24 (r 31) | 4.37 | | | 0 | `logs/rx.2026-10-03.nomul.log` |
The word-level prologue `(x ^ C) * MUL`: over 2^20 inputs the most frequent value of `rot_r(g(x)) ^ g(rot_r(x))`
occurs at most 3 times for every word and every r on all three days (`logs/rx-word.<day>.real.log`, the
`rxw_worst` lines), against 2^20 of 2^20 without the multiply. The odd multiply by a random constant is not
rotational to any measurable degree, and one application already shows no per-bit bias. Rotational-XOR does not
reach 1 application.
### 4.5 The fold of the multiply layer
One application is `D o P_rk`, with `P_rk(s)_i = (s_i ^ (RC_i + rk)) * MUL_i` and `D` the double round (fixed per
day). Multiplication by an odd constant distributes over modular addition and over nothing else in `D` (XOR,
rotation); the XOR with a constant commutes with XOR and rotation and with nothing else (addition, multiply). A fold
across applications would need one of the identities below. Each was tested on 2^20 random inputs on every day
(`logs/fold.<day>.log`):
| Identity a chip would need | Holds on | Meaning |
|---|---|---|
| `(xa ^ Ca) * ma + (xb ^ Cb) * mb = ((xa ^ Ca) + (xb ^ Cb)) * ma` for the four column pairs (0,4), (1,5), (2,6), (3,7) | 0 of 1,048,576 for every pair on every day (`MUL` distinct in every pair) | the multiply does not fold into the first add of a quarter round; it would if a column pair drew the same `MUL` (probability 2^-31 per pair per day, the weak-day class of F4) |
| `(x ^ C) * m = (x * m) ^ (C * m)`, or `= (x * m) ^ C'` for any single `C'` | 0 of 1,048,576; the best single `C'` agrees on 33 of 1,048,576 (2^-15) | the constant cannot be moved past the multiply, so application j + 1's prologue cannot share application j's multiply |
| an XOR constant on one word commuting with the bare double round (so the next prologue's constant could be folded back) | 0 of 65,536 for every word | every word's value feeds an add inside the double round |
| the MSB passing the prologue and the add for free; the LSB passing the prologue | 1,048,576 of 1,048,576 each | the structural residue: the only free passages, both moved by the rotations (the family deaths in 4.2 and 4.3) |
So k applications cost k times one application, 128 hoisted operations each (16 multiplies, 32 adds, 32 XORs, 32
rotations with the constants hoisted); `chip-model-v3.md` 5.2's 9,360 per item stands. The trail weights of 4.2
and 4.3 growing with k is the quantitative side of the same fact: a composition that collapsed to one application's
shape would keep one application's trail weights.
## 5. Gate and verdict
Gate (plan 4.2 F2, 1.4 (1)): no distinguisher or shortcut beyond 2 of the 8 applications between dependent reads,
after the stated search.
| Line of attack | Reach | Verdict |
|---|---|---|
| Differential, general model (Markov on the multiply, exact add rule, SAT) | one application: best trail weight 10 to 12 on three days, verified on the real code; two applications: no trail at or below weight 20 to 24 within 7,200 s per job (not closed); the MSB family dies at two applications on every day | nothing reaches 2 applications below 2^-20 |
| Linear, general model (piling-up, SAT) | one application: weight 1 (the LSB residue); two applications: no trail at or below 20 to 24 within the timebox; the LSB family dies at two | nothing reaches 2 applications below 2^-20 |
| Rotational-XOR | no per-bit bias at one application (max abs z 4.0 to 4.6 at 2^20 states, noise ceiling 4.3); 0 exact pairs; the multiply prologue is rotational on at most 3 of 2^20 inputs; the bare double round fires at 134 | does not reach 1 application |
| Algebraic fold of the multiply layer | every identity a fold needs holds on 0 of 2^20 inputs on every day; k applications cost k | no shortcut |
Verdict: PASS with the effort bound stated: about 60 solver jobs, 2 to 29 minutes each, on three day keys; the
reduced-round margin reached is one application fully characterised (weights 10 to 12 differential, 1 linear) and
two applications with no trail under weight 20 to 24, three with none under 29 to 35 (differential) and 24 to 28
(linear), four with none under 39 to 47 and 24, against 8 applications between reads, so the margin between what the
search reaches and what the construction uses is at least 4 applications at the solver's cap. What this does not do is in section 7; the lower bound is the paid question.
## 6. Consequences per tier
No shortcut, so no tier moves: a home card, a rig and a pool pay the 72 applications per item the verifier pays;
a chip with a fixed datapath pays them too (the fold test), which is what `chip-model-v3.md` 5.2's 9,360 ops per
item assumes. `mixer_mult` stays 8; the verifier measurement of F6 stands unchanged.
## 7. What this does not do
- It does not bound the mixer from below: the general models are trail models (Markov for the multiply's
differential, piling-up for the linear), and the family models are exact only inside their families. The firm's
job (funding.md B5 rank 1) is the effort-bounded version of the same search with their tools.
- Three days, not a census: the ROT, MUL, RC classes over 2^24 days are F4's row. One cheap addition for F4 from
this harness: the MSB-family death at k = 2 (`model.py search --kind diff --family msb --apps 2`) runs in seconds
per day, and a day where it does not die is a weak day of the kind the gate is about.
- Differential and linear only, as the row says: no boomerang, no integral or cube property, no related-key (the
round keys are public constants).

# F3: the chained cache's j + 1 bound and the storage-against-recompute curve
Attack-pass row F3 of `docs/plans/cryptanalysis.md` section 4.2 (the record is `docs/analysis/attack-pass-2026-10.md`). Run 7 October 2026, 09:10 to 09:12 UK (08:10 to 08:12 UTC in the logs), on igneum-build-1. Verdict: PASS on all three gate clauses. No line (s, j) is derivable in fewer than j + 1 block evaluations without an earlier line, by an exhaustive search over the block dependency graph extracted from the code at 64 and 1,024 lines, cross-checked by an exhaustive pebbling search over every configuration at 10 lines. The storage-against-recompute curve over cache lines is monotone from f = 1/64 to 1. The f = 1 point is unchanged.
## Target
| Item | Value |
|---|---|
| Commit | 924288d1 (the brief); the worktree HEAD moved to 11b375a0 during the run; `igneum-pow/src/memhard.rs` is byte-identical at both (blob ad42470b, `git diff --stat 924288d1 HEAD -- igneum-pow/src/memhard.rs` empty) |
| Construction, from the code | `Cache::fill_segment`: `in_j = prev XOR (sigma || K || seg || j || tag)`, `line_j = chacha_block(in_j)` where `chacha_block(x) = ChaCha12core(x) + x`, `prev_0 = 0`, `prev_j = line_{j-1}`; 64 lines per segment, 2^16 segments, 2^26 words (256 MiB) |
| Reads | `derive_items_mask`: 8 dependent reads per item at line index `s[0] AND mask`, so the segment and j of a read are uniform over the 2^22 lines (F8 checks the uniformity) |
| Known-failed shape | a line (s, j) computable in fewer than j + 1 block evaluations without an earlier line of segment s (the address-steering shape of the MTP break, Dinur and Nadler 2017, needs a data-dependent chain; this chain's inputs are fixed by the key, so the shape to search is a structural shortcut on the dependency graph) |
| Gate | no derivation under j + 1 blocks; the curve monotone; the f = 1 point unchanged |
| Prior evidence | none to re-gate: the `ca2-cache` branch named in the status board is the hot-table experiment (`docs/plans/hot-table.md`), not a chain analysis |
## Method
The model is the code, not the prose. `tools/attack/f3-cache/src/main.rs` runs one chain function, written in the shape of `memhard.rs` (the quarter round, the 6 double rounds, the feed-forward, the prev XOR, the constant block), generically over two word types:
| Word type | What it computes | Use |
|---|---|---|
| `u32` | the real arithmetic | `verify`: bit-exact against `Cache::fill_segment` on 16 (key, segment) pairs and against `chacha_block` on 100,000 random inputs |
| taint set | which block outputs a value depends on (add, xor, rotate = union) | `search`: the direct-parent graph of every block, with each computed line relabelled to the single node {j} so parents are direct, not transitive; plus the 16 x 16 (output word, input word) dependency matrix of one block |
The exhaustive search: for every target line j, the minimum number of block evaluations with nothing stored is the size of the backward closure of j on the extracted graph (every non-stored block in the closure must be evaluated at least once; once each in dependency order suffices). `pebble` checks that formula against an exhaustive 0-1 BFS over every pebble configuration (place on a node whose parents are pebbled at cost 1, remove at cost 0) for all 2^10 stored sets x 10 targets on each of the three graphs: 10,240 pairs per graph, 0 mismatches. Two deliberately broken chains are the known-fail cases: `skip2` (line j fed from line j - 2) and `nofeed` (no previous line fed in). The curve: for f = 1/64 to 1 (fraction of cache LINES held), the blocks per read on the naive pattern of `funding.md` B2 rank 2 (every L/n-th line from line 0) and on the optimal pattern (exact DP over chunk lengths; brute force over every C(64, n) set for n up to 8, 4,426,165,368 sets at n = 8); ops per item = 9,360 mixer ops (chip-model-v3.md 5.2) + 8 reads x blocks per read x ops per block (608 counted from the code: 48 quarter rounds x 12, 16 feed-forward adds, 16 input XORs; also at MEMHARD.md's approximate 700). Three more checks on the real function: single-bit avalanche and a differential-independence test on `chacha_block`, a census of every line of the real 2^22-line cache for the day key 2026-10-03, and one-core timings of a block, a mixer application, an item and a line recompute.

Box hygiene: the box checkout of every `build-remote.sh` run on this worktree executes `git clean -fd` at `/srv/builds/igneum-wt-attack` (remote-run.sh `checkout_tree`), which deletes any untracked scratch directory there. `attack-f3/` and `attack-f3-venv/` are listed in that mirror's `.git/info/exclude` so they survive; nothing in the tree was touched. The F1 lane's `attack-f1-venv/` is untracked and unprotected and will be removed by the next build from any agent on this worktree.
## The two firings and the pass
| Chain | Direct parents (taint trace) | Lines under j + 1 at 64 lines | Cheapest derivations | Exhaustive pebbling at 10 lines, cost per target | Verdict | Log |
|---|---|---|---|---|---|---|
| real (the code) | j - 1 for all 63 lines after line 0 | 0 of 64 | none; every line costs exactly j + 1 (mean 32.5) | 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 | PASS | `r1-search-real-64.log`, `r1-pebble-10.log` |
| real, 1,024-line model | j - 1 for all 1,023 lines after line 0 | 0 of 1,024 | none (mean 512.5) | same graph rule | PASS | `r1-search-real-1024.log` |
| skip2 (known fail A) | j - 2 for 62 lines, none for 2 | 63 of 64 | j = 1 in 1, j = 63 in 32 (mean 16.5) | 1, 1, 2, 2, 3, 3, 4, 4, 5, 5 | FIRE | `r1-search-skip2-64.log`, `r1-search-skip2-1024.log` |
| nofeed (known fail B) | none for all 64 | 63 of 64 | every line in 1 block (mean 1.0) | 1 x 10 | FIRE | `r1-search-nofeed-64.log`, `r1-search-nofeed-1024.log` |
`verify` (`r1-verify.log`): the model chain equals `Cache::fill_segment` on keys {day 2026-10-03, 3 random} x segments {0, 1, 12345, 65535} (16 of 16), `block == chacha_block` on 100,000 of 100,000 random inputs, the 1,024-line model's first 64 lines equal the 64-line chain, and both broken variants differ from the real chain from line 1 (line 0 equal, as the rule predicts). The block's word dependency matrix is full on every variant (256 of 256 pairs), so the firings come from the chain rule alone.
## Derivation cost per line on the model segment (real chain, nothing stored)
| j | blocks to derive line j | j + 1 | Log |
|---|---|---|---|
| 0 | 1 | 1 | `r1-search-real-1024.log` |
| 1 | 2 | 2 | |
| 3 | 4 | 4 | |
| 7 | 8 | 8 | |
| 15 | 16 | 16 | |
| 31 | 32 | 32 | |
| 63 | 64 | 64 | (the last line of a real segment; `r1-search-real-64.log` lists all 64) |
| 127 | 128 | 128 | |
| 255 | 256 | 256 | |
| 511 | 512 | 512 | |
| 1,023 | 1,024 | 1,024 | |
All 1,024 lines were searched (0 under j + 1, mean 512.5 = (L + 1) / 2); the 64-line table in `r1-search-real-64.log` has every j from 0 to 63 at exactly j + 1.
## Store patterns on the real 64-line segment
Blocks per read averaged over j uniform in 0..63. "Naive" is `funding.md` B2 rank 2's pattern (every k-th line from line 0). "Optimal" is the exact minimum over store sets of that size (DP; brute force over every set for n up to 8, agreeing with the DP on every row it ran). The gap formula equals the closure cost on the extracted graph on 2,000 of 2,000 random stored sets (`r1-store-64.log`).
| f | Stored lines n | SRAM held | Naive blocks per read | Optimal positions | Optimal blocks per read | Brute force over C(64, n) sets |
|---|---|---|---|---|---|---|
| 1/64 | 1 | 4 MiB | 31.5 | [32] | 16.0 | 16.0 (64 sets) |
| 1/32 | 2 | 8 MiB | 15.5 | [21, 43] | 10.5 | 10.5 (2,016 sets) |
| 1/16 | 4 | 16 MiB | 7.5 | [12, 25, 38, 51] | 6.094 | 6.094 (635,376 sets) |
| 1/8 | 8 | 32 MiB | 3.5 | [7, 15, 22, 29, 36, 43, 50, 57] | 3.172 | 3.172 (4,426,165,368 sets, 11.2 s) |
| 1/4 | 16 | 64 MiB | 1.5 | [3, 7, 11, ..., 55, 58, 61] | 1.453 | not run (DP exact) |
| 1/2 | 32 | 128 MiB | 0.5 | odd lines | 0.5 | not run |
| 1 | 64 | 256 MiB | 0 | all | 0 | not run |
The 1,024-line model (`r1-store-1024.log`) gives 29.68 / 15.05 / 7.40 / 3.48 / 1.50 / 0.5 / 0 at the same f on the optimal pattern: the naive and optimal patterns converge as the chain lengthens, because the wasted stored line 0 and the end effects are a smaller share.
## The curve: ops per item against the fraction of cache lines held (real 64-line segment)
Ops per item = 9,360 (the 72 mixer applications, hoisted, plus the fold: chip-model-v3.md 5.2) + 8 reads x blocks per read x ops per block. `r1-curve-64.log` (608 ops per block, counted) and `r1-curve-64-memhard.log` (700, MEMHARD.md item 4). Ops per hash = 128 x ops per item + 512. MH/s at the chip model's 50 T op/s budget (approximate, chip-model-v3.md section 1).
| f (lines held) | SRAM | Blocks per read, naive / optimal | Ops per item, naive, 608 | Ops per item, optimal, 608 | Ops per item, optimal, 700 | Ops per hash, optimal, 608 | MH/s at 50 T op/s, optimal, 608 |
|---|---|---|---|---|---|---|---|
| 1/64 | 4 MiB | 31.5 / 16.0 | 162,576 | 87,184 | 98,960 | 11,160,064 | 4.5 |
| 1/32 | 8 MiB | 15.5 / 10.5 | 84,752 | 60,432 | 68,160 | 7,735,808 | 6.5 |
| 1/16 | 16 MiB | 7.5 / 6.094 | 45,840 | 39,000 | 43,485 | 4,992,512 | 10.0 |
| 1/8 | 32 MiB | 3.5 / 3.172 | 26,384 | 24,788 | 27,122 | 3,173,376 | 15.8 |
| 1/4 | 64 MiB | 1.5 / 1.453 | 16,656 | 16,428 | 17,498 | 2,103,296 | 23.8 |
| 1/2 | 128 MiB | 0.5 / 0.5 | 11,792 | 11,792 | 12,160 | 1,509,888 | 33.1 |
| 1 | 256 MiB | 0 / 0 | 9,360 | 9,360 | 9,360 | 1,198,592 | 41.7 |
Monotone: ops per item is non-increasing in f on both patterns at both op counts and on the 1,024-line model (`CURVE ... monotone non-increasing` in all three curve logs). The f = 1 point: 9,360 ops per item, 1,198,592 ops per hash, 41.7 MH/s at 50 T op/s, which is the chip-model-v3.md section 5.4 row "none, f = 0" of the published ITEM curve (the on-die-cache recompute chip of sections 1 to 3). The published item curve stores dataset ITEMS and is a different curve: its f = 1 point (GDDR7, 166.4 MH/s, 0.466 microjoules per hash) contains no cache read and no mixer op, so nothing in this row touches it. `funding.md` B2 rank 2's arithmetic reproduces on the naive pattern at 700 ops per block: 3.5 blocks per read, 2,450 ops per line, 19,600 per item on top of the mixer, 13.5 MH/s (50 T / (128 x 28,960 + 512)).

| One ChaCha12 block, dependent chain of 20,000,000 | 66.64 ns | |
| One mixer application (class v4 parameters), dependent chain of 20,000,000 | 17.29 ns | block / application = 3.85 (counted ops 608 / 128 = 4.75) |
| One item against the 256 MiB cache, batches of 32 | 1,326 ns | 72 applications = 1,245 ns; the 8 dependent reads and the fold add 81 ns because the batch overlaps them |
| One line recomputed from nothing, 312,500 random (seg, j) | 2,734 ns | 32.5 blocks per line on average, 84.1 ns per block inside the chain |
| The 256 MiB cache fill, one thread | 0.36 to 0.4 s | 86 ns per block with the writes |
In measured time, holding every 8th line at the optimal placement makes an item cost 72 + 8 x 3.172 x 3.85 = 170 mixer-application equivalents against 72, a 2.36x penalty per item (2.65x in counted ops). Holding one line in 64 costs 72 + 8 x 16 x 3.85 = 565, a 7.8x penalty.
## Checks on the real function (`r1-avalanche.log`, `r1-census.log`)
| Check | Result |
|---|---|
| Single-bit avalanche of `chacha_block`, 1,048,576 flips | mean 256.00 of 512 output bits change (ideal 256), min 200, max 312 |
| (output word, input word) pairs where an output word did not change | worst count 0 of 1,048,576 |
| Chain step: one bit of line j - 1 flipped | line j changes 255.96 bits, line j + 1 changes 255.94 (131,072 flips) |
| Differential independence: B(x ^ d) ^ B(x) == B(y ^ d) ^ B(y) over 262,144 (x, y, single-bit d) | 0 cases |
| Census of the real cache, day key 2026-10-03 | 4,194,304 of 4,194,304 lines distinct, 0 all-zero lines: no two chains merge and no block input repeats |
## Gate
| Clause | Result | Where |
|---|---|---|
| No derivation under j + 1 blocks | 0 of 64 and 0 of 1,024 lines under j + 1 on the extracted graph; the formula exact on 10,240 of 10,240 exhaustive pebbling cases; both known-fail chains fire | `r1-search-real-64.log`, `r1-search-real-1024.log`, `r1-pebble-10.log` |
| The curve monotone | non-increasing on both patterns, both op counts, both segment lengths | the three `r1-curve-*.log` |
| The f = 1 point unchanged | 9,360 ops per item = chip-model-v3.md 5.4 "none, f = 0" row; the item curve's GDDR7 f = 1 row (166.4 MH/s, 0.466 microjoules) untouched | `r1-curve-64.log` |
Verdict: PASS.
## Observations that are not findings
| Observation | Number | What it means | What I propose |
|---|---|---|---|
| `funding.md` B2 rank 2 prices the honest trade-off at the naive placement | 3.5 blocks per read at f = 1/8 against 3.17 optimal (9.4 percent less); 31.5 against 16.0 at f = 1/64 (2.0x less, because storing line 0 is worthless: it costs 1 block anyway) | the chip at f = 1/8 reads 15.8 MH/s (608 ops per block, optimal placement) or 14.4 (700, optimal) against `funding.md`'s 13.5 (700, naive); still 0.38x of the full SRAM mirror's 41.7 and 0.12x of the 5090's 136.1 (chip-model-v3.md section 2); the curve stays monotone, so the published verdict (the partial chip is not the threat, the full mirror beats it) stands | one sentence in `funding.md` B2 rank 2: "holding every 8th line at the best placement costs 3.2 blocks per read (3.5 for every 8th line from line 0)". Not edited here: outside this row's two files; for main to serialise |
| The chain's hardness per line is sequential time, not memory | one pebble (64 bytes) over j + 1 steps: the cumulative memory of deriving a line is about 64 x (j + 1) byte-steps | the chain protects the cache by op count, which is exactly what the curve prices in ops; parallel attackers pipeline items and pay E(f) x 608 ops per read in throughput, E(f) block latencies in latency; a chip that holds nothing (f = 0) pays 32.5 x 608 = 19,760 ops per read, 158,080 per item, 167,440 with the mixer (17.9x the mixer alone), 2.3 MH/s at 50 T op/s | nothing to move; the public model should keep quoting ops, never bytes, for this piece |
| What this row does not cover | a cryptanalytic shortcut inside `chacha_block` in this chaining mode (the differential and avalanche tests are sanity checks, not a bound) | the paid engagement's rank 2 question (`funding.md` B2) stays worth the money; plan 4.2 says the internal pass cannot prove the chain's trade-off curve | none |
## Consequences per user tier
| Tier | What this row changes |
|---|---|
| Home miner, one 8 / 12 / 16 / 24 or 32 GB card, any vendor, any OS | nothing: the honest miner holds the dataset, the verifier holds the 256 MiB cache; no memory, hash rate, or power figure moves |
| Rig, pool user | nothing |
| Chip builder | the partial-cache chip is priced 9 percent better at f = 1/8 and 2x better at f = 1/64 than `funding.md` says, and is still worse than the full SRAM mirror at every f below 1; the public per-joule sentence (evidence row 17, 2.1x at k = 1) rests on the item curve's f = 1 point, which this row leaves untouched |
| The paid review | the firm receives this record and the harness; rank 2's open question is the block function in chaining mode, not the graph |

# F4. The weak-day census: 2^24 day keys through `MixParams::with_shape`
Attack pass row F4 (`docs/plans/cryptanalysis.md` section 4.2; the gate is section 1.4 (3) and `funding.md` B5
rank 3; the threat is `funding.md` B2 rank 3). Run 7 October 2026, 09:10 to 09:55 UK, on igneum-build-1 by the
attack-f4 agent (the verifier timing row of 6.6 queued behind other lanes' holds). Every number below cites its log.
## Verdict
**PASS on the gate read against M2, the DSP-bound per-day datapath (0 days over 1.1x in 2^28), and on every named
weak class; the generous bound M1 (every multiply in LUT adders) exceeds the gate at 3.26e-4 of days as the tail of a
sum, not a class, and is routed to main as a bound finding with a rejection-and-redraw rule for the next class.
Class v4 is not changed.**
Which metric the 1.1x gate reads against, and why: M2. The gate (plan 1.4 (3)) asks for the fraction of days in a
weak class, and M1's excess has no class behind it (section 6.2: the exact 16-fold convolution of one random NAF
weight predicts the census to 0.6 percent). A per-day FPGA attacker who builds the 16 multiplies in LUT shift-add
trees is building the slower design: those trees are 72 percent of M1's cost (167 of 231 adders), and DSP blocks
take that cost off the fabric, so the design that wins is DSP-bound, where the day's constants move nothing unless a
word has NAF weight at most 3, which happens on no day in 2^28 for two words. M1 is still reported in full because
the brief asks for the generous bound, and because a two-line rule closes it for nothing.
| Metric | Days over 1.1x in 2^24 | Fraction | Days over 1.1x in 2^28 | Fraction | Gate 2^-20 = 9.54e-7 | Log |
|---|---|---|---|---|---|---|
| M1: per-day LUT datapath, adders per mixer application, against the census median | 5,476 | 3.264e-4 | 87,426 | 3.257e-4 | OVER, by 342x | `census-2p24.md`, `census-2p28.md` gate table |
| M1 exact expectation (16-fold convolution of the NAF-weight table over all 2^31 odd constants) | 5,441 | 3.243e-4 | | | the census is the tail of a smooth sum, not a class | `expect-231.log` last line |
| M2: DSP-bound datapath, 16/(16 - k), k = words of NAF weight at most 3 | 0 | 0 | 0 | 0 | under | `census-2p24.md`, `census-2p28.md` M2 table |
| ROT value and RC value on a per-day datapath | 0 | 0 | 0 | 0 | under (exact 0 ops moved, section 3) | section 3 |
The gate as written fails under M1 only. What M1 finds is not a weak class: the per-day cost of the 16 constant
multipliers is a sum of 16 NAF weights (mean 231.1 adder-equivalents per application, sd 6.19), and 1 day in 3,070
sits 3.4 sigma below the median, where a bitstream synthesised for that day pays 10 to 19 percent fewer adders. The
worst day in 2^28 reads 1.19x (day 27,952,752, cost 194). The exact expectation predicts the census to 0.6 percent.
Section 7 prices the consequence (0.004 percent more hashes a year for an all-LUT FPGA that re-synthesises every
day, nothing for a chip or a GPU) and section 8 gives the rejection-and-redraw rule that closes it.
## 1. Target
| Item | Value |
|---|---|
| Commit | 924288d1 (the brief); the worktree HEAD moved to 11b375a0 during the pass (F5 and F6 records); `git diff 924288d1 11b375a0 --stat -- igneum-pow/src` is empty, so the target code is the same |
| Code | `igneum-pow/src/memhard.rs` `MixParams::with_shape` (lines 189 to 215): `SplitMix64::new(key[0] as u64 \| (key[1] as u64) << 32)`, then `ROT[0..7] = 1 + below(31)`, `MUL[0..15] = next() as u32 \| 1`, `RC[0..15] = next() as u32`; no rejection rule |
| Day key | `bind::day_bytes(d) = "igneum-day/" \|\| d_le64`, `key = seed_words_from_bytes(day_bytes)` (the interim day rule, `bind.rs` lines 30 to 68); the genesis day index is 20,729 (`bind.rs` test `day_bytes_layout`) |
| Shape | `Shape::for_class(&V4_CLASS)`: mixer x8, cache 2^26 words, no derivation program (asserted by the harness) |
| Mixer | `memhard::mixer`: per word `(s ^ (RC + rk)) * MUL`, then one ChaCha double round with `ROT[0..3]` on the columns and `ROT[4..7]` on the diagonals; 72 applications per item under x8 |
| Census set | 2^24 consecutive chain days from 20,729 (the gate run), and 2^28 (the extended run); the first 36,525 of them are the chain's public calendar for the next 100 years under the interim rule |
The 64-bit seeding fact (F7 covers the spec's intent): the 40 draws depend on `key[0] | key[1] << 32` alone, so the
stream can produce at most 2^64 distinct parameter sets whatever the key's other 192 bits hold. Over the 2^24 census
days the 64-bit seeds were all distinct (0 collisions, expected 7.6e-6; `census-2p24.md` "64-bit seeding" line).
`below(31)` is `next() % 31` without rejection: the bias per rotation value is 2^-64 and is ignored.
## 2. Known-failed shape
A day key whose drawn `ROT`, `MUL` or `RC` gives a fixed datapath a gain over 1.1x: all-equal `ROT` (31^-7 per day,
MEMHARD.md section 3 item 3, untested until now), `MUL = 1` (2^-31 per word), pairs summing to 32, small rotation
amounts, low-weight multipliers, `RC + rk = 0`.
## 3. The gain metrics (exact, structural)
The verifier and every GPU run the same instructions on every day (`rotate_left` by a register amount, `wrapping_mul`,
no branch on a drawn value), so wall time cannot move with the draw; the only attacker a weak day helps is one who
builds the day's constants into logic. That is an FPGA bitstream synthesised per day (hours of compile against a
public calendar), never a taped-out chip. Costs are in 32-bit adder-equivalents per mixer application:
| Element of one application | Generic datapath | Per-day datapath |
|---|---|---|
| 16 x `s ^ (RC + rk)` | 16 | 0 (constant XOR: inverters, absorbed into the next LUT) |
| 16 x `* MUL` | 16 multipliers (value-independent) | M1: `NAF(MUL_i) - 1` adders each (canonical signed-digit shift-add); M2: a DSP block each, value-independent, except a word of NAF weight at most 3 moves to 2 LUT adders and frees its DSP |
| 8 quarter rounds: 32 adds, 32 XORs | 64 | 64 |
| 32 rotations | 32 barrel shifters | 0 (wiring) |
* **M1** `cost = 64 + sum_i (NAF(MUL_i) - 1)`; gain of a day = census median cost / the day's cost. The generous
bound: optimal single-constant multiplication is below NAF for every constant and the ratio between days is what
is measured.
* **M2** gain = `16 / (16 - k)` on a DSP-bound design, k the words of NAF weight at most 3.
* **ROT** and **RC** hand a per-day datapath exactly 0 ops at any value (wiring and inverters); on a generic
datapath a rotation costs the same at every amount and `RC + rk = 0` removes one XOR of 10,368 ops per item
(1.0001x). They are censused as structure, and the worst members are measured for diffusion (section 6), the
only other thing a rotation draw could move; a bit-exact verifier never lets a chip skip an application, so
diffusion is reported and is not a gain.
## 4. Harness
| Item | Path or line |
|---|---|
| Crate | `tools/attack/f4-weakday/` (`Cargo.toml` with `igneum-pow = { path = "../../../igneum-pow" }` and an empty `[workspace]`; `src/main.rs`); `igneum-pow` untouched |

Every class sits at its expectation (the largest deviation, "ROT max multiplicity >= 4", is against a first-order
bound). The worst member of every class owes its gain to its MUL draw (M1 is a MUL-only quantity); the class itself
moves nothing. No day in 2^28 has two words of NAF weight at most 3, so M2 never exceeds 1.067x.

| 200 | 1.155x | 10 | 8.34e-7 | 8.62e-7 |
| 205 | 1.127x | 250 | 2.94e-5 | 2.87e-5 |

| 210 | 1.100x | 3,887 | 5.58e-4 | 5.64e-4 |
| 231 (median) | 1.000x | 1,079,174 | 0.522 | 0.522 |
Mean cost 231.113 (exact 231.111), sd 6.190 (exact 6.190). The 2^28 minimum is 194 (1.191x, day 27,952,752). A
single NAF weight has mean 11.44 and sd 1.55 over the 2^31 odd constants (`expect-231.log`).
### 6.3 ROT structure (`census-2p24.md` histograms)
| Distinct rotation amounts a chip must wire | Days in 2^24 | Fraction | Expected S(8,d) 31_d / 31^8 |
|---|---|---|---|
| 1 | 0 | 0 | 3.63e-11 |
| 2 | 4 | 2.4e-7 | 1.4e-7 |
| 3 | 530 | 3.16e-5 | 3.05e-5 |
| 4 | 25,476 | 1.52e-3 | 1.51e-3 |
| 5 | 421,405 | 0.0251 | 0.0251 |
| 6 | 2,773,843 | 0.1653 | 0.1653 |
| 7 | 7,302,781 | 0.4353 | 0.4351 |
| 8 | 6,253,177 | 0.3727 | 0.3729 |
Small amounts {1, 2, 30, 31} and byte-aligned amounts {8, 16, 24} follow Binomial(8, 4/31) and Binomial(8, 3/31) to
within 3 percent in every bin.
### 6.4 Diffusion of the worst members (`avalanche.log`: 2,048 states x 512 input bits, mean and minimum per-output-bit flip probability)
| Day | Why | ROT | After 1 application, mean / min | After 2, mean / min |
|---|---|---|---|---|
| 20,729 | genesis, same-word pair 11 + 21 = 32 | 6 25 5 25 29 11 9 21 | 0.461 / 0.383 | 0.500 / 0.498 |
| 4,819,563 | M1 worst in 2^24 | 26 18 8 30 24 24 6 9 | 0.467 / 0.426 | 0.500 / 0.499 |
| 27,952,752 | M1 worst in 2^28 | 11 26 11 7 6 20 20 3 | 0.460 / 0.392 | 0.500 / 0.498 |
| 11,482,247 | 3 distinct amounts, multiplicity 5 | 12 19 19 4 19 12 19 19 | 0.453 / 0.374 | 0.500 / 0.499 |
| 14,330,190 | all 8 amounts in {1, 2, 30, 31} | 1 1 2 31 1 31 1 31 | 0.331 / 0.196 | 0.4995 / 0.497 |
| 332,924 | NAF weight 3 word, three amounts of 1 | 1 23 1 1 12 11 16 18 | 0.458 / 0.370 | 0.500 / 0.498 |
| 196,441,106 | `MUL = 1` word (2^28) | 30 24 23 5 11 28 12 9 | 0.461 / 0.364 | 0.500 / 0.499 |
| 109,542,046 | `RC = 0` word (2^28) | 28 5 4 31 25 28 12 4 | 0.459 / 0.348 | 0.500 / 0.499 |
| planted all 1 | the worst all-equal draw | 1 x 8 | 0.345 / 0.216 | 0.500 / 0.499 |
| planted all 16 | half-word swaps | 16 x 8 | 0.387 / 0.312 | 0.500 / 0.499 |
| planted all 7 | | 7 x 8 | 0.464 / 0.400 | 0.500 / 0.498 |
The slowest draw that can exist (all rotations by 1, probability 31^-8 per day) reaches full avalanche after 2 of the
8 applications between cache reads; the worst real day in 2^28 (all amounts in {1, 2, 30, 31}) the same. No draw
gives an attacker a shorter dependency between reads than the round margin F2 measures.
### 6.5 The chain's first 100 years (`census-100y.md`: days 20,729 to 57,253 under the interim day rule)
| Item | Value |
|---|---|
| Days over 1.1x under M1 | 6 of 36,525 (1.64e-4; the 2^24 rate predicts 12) |
| First such day | 22,633 (genesis + 1,904 days, about 5.2 years in), cost 208, 1.111x |
| Worst day | 29,337 (genesis + 8,608 days, about 23.6 years in), cost 206, 1.121x |
| Days at exactly 1.100x (cost 210) | 6 more: 25,605; 28,102; 31,573; 33,710; 42,573; 54,884 |
| M2 k >= 2 | 0 |
| Genesis day 20,729 | cost 226, 0.978x; the next four devnet days (20,730 to 20,733) read 0.987x, 1.036x, 0.947x, 0.979x |
| Rotation structure | 1 day with 2 distinct amounts (57,146, genesis + 36,417, cost 225, 1.027x), 46 with 4, none with 3 or fewer otherwise; no day with a `MUL` of NAF weight under 4 |
### 6.6 Verifier time (exclusive hold, `timing.log`)
A confirmation row only: the verifier's code path is value-independent, so the exact metric is the op count above
and a wall-time difference between days can only be noise. Queued on the box at 09:47 UK (`timing.sh`, nohup, an
exclusive `flock -x -w 7200` behind the shared holds of F1, F2, F8, F9, F10 and F7 and the queued exclusive hold of
F6; the first attempt, queued 09:14 UK, was attached to a Mac ssh session and was withdrawn in favour of the nohup
job). Cores 16 and 64, nice 19, `--warps 100`, day 20,729 against day 4,819,563 (the 2^24 M1 worst), A B A B.
| Day | Cold warp 0 (ms) | Average per warp, 100 warps (ms) |
|---|---|---|
| 20,729 (genesis) | pending (`timing.log`) | pending |
| 4,819,563 (M1 worst, 1.173x) | pending (`timing.log`) | pending |
The verdict does not rest on this row.
### 6.7 The worst days in full (`worst-days.log`, `export-29337.log`)
The worst day in adders per application against the census median, in each set. M1 is the sum of the 16 NAF weights
less 16 plus 64. Every one is an ordinary draw whose 16 weights happen to sum low; none has a word under NAF weight 7.
| Set | Chain day | Years after genesis | ROT | MUL words (hex) | NAF weights | M1 cost | Gain vs median 231 | M2 |
|---|---|---|---|---|---|---|---|---|
| The public calendar, first 36,525 days (what an auditor runs) | 29,337 | 23.6 | 24 12 18 11 14 26 29 21 | 3fe4d03b 227c2043 06011627 40c10137 00234d99 063071d9 91e5abb7 035240b1 f40bfe47 809251b9 1ce999ef 940b381d da13a021 f75f8ba7 3f59bca7 01310e05 | 9 8 9 8 10 10 12 10 9 10 12 11 10 11 11 8 (sum 158) | 206 | 1.121x | 1.000x |
| 2^24 (the gate census) | 4,819,563 | 13,139 | 26 18 8 30 24 24 6 9 | a0653c83 a09de525 810085fb 6a00eba1 bf8205ff bba82079 f27da4c3 2cb80223 6001efcf 1c2814f7 ae9d09d7 ffedd7b7 943dde01 39ff47e1 0513a83f c028eef9 | 11 11 7 10 7 10 12 10 7 9 13 8 8 8 9 9 (sum 149) | 197 | 1.173x | 1.000x |
| 2^28 (extended) | 27,952,752 | 76,481 | 11 26 11 7 6 20 20 3 | f15eb273 227a08f1 20f822e1 6d477779 8d9b3aff 03040503 27fff521 bfd9ce7d 7708000d 5d60ba11 2d40005b f07e10d7 1deefdb1 4881e821 01e1fc71 3ee7c39b | 13 9 8 11 11 7 7 11 7 11 9 9 8 8 7 10 (sum 146) | 194 | 1.191x | 1.000x |
Reproduction, through the harness: `attack-f4 day --index 29337 --median 231` (and 4819563, 27952752). Through
`igneum-pow` itself, with the day bytes `"igneum-day/" || d_le64` as hex (day 29,337 = 0x7299):
`igneum-pow export --seed x --epoch-hex edc4fa844da9dc98d37e965176f6558a31560e40502ab3ae5491b21aaaabfb07 --day-hex 69676e65756d2d6461792f9972000000000000 --program-class v4 --out <dir>`
writes the day's constants into the pack's `memhard.h` as `IGNEUM_MIX_ROT_INIT` and `IGNEUM_MIX_MUL_INIT`; run on the
box at 09:52 UK (`export-29337.log`, OVERALL PASS, cache FNV-1a 64 `1979492fb76b52ce`), the pack's 8 rotations and
16 multipliers equal the harness's word for word. The day-hex strings of the other two days are in section 6.2's
source list (`census-2p24.md` and `census-2p28.md`, "The 16 lowest-cost days"): `...2f6b8a490000000000` and
`...2f7086aa0100000000`.
## 7. Gate line and consequences
Gate (plan 1.4 (3)): the fraction of days with any gain over 1.1x under 2^-20.
| Model | Fraction over 1.1x | Gate | What the number means per tier |
|---|---|---|---|
| M1 (per-day LUT bitstream) | 3.26e-4 (1 day in 3,070; 2^24 and 2^28 agree; exact expectation 3.24e-4) | FAIL by 342x | An FPGA farm that re-synthesises its bitstream every day gains 10 to 19 percent on those days: 3.26e-4 x about 0.12 = 4e-5 of a year's hashes, 0.004 percent. The FPGA lane is already behind every GPU tier on reads per watt (F5: 10 to 20 M reads/s/W against the gate's 27 M), so no home miner (8, 12, 16, 24 or 32 GB), rig or pool on any vendor or OS sees a competitor appear, and no day's difficulty moves by a measurable amount |
| M2 (DSP-bound FPGA) | 0 in 2^28 | PASS | nothing moves for any tier |
| Chip (programmable constants, the chip-model-v3 recompute chip) | 0 by construction | PASS | nothing moves; a taped-out chip cannot specialise per day |
| GPU and the CPU verifier | 0 by construction | PASS | every tier pays the same ops on every day |
What the worst day buys, priced for the per-day LUT datapath (the M1 attacker) on the worst calendar day, 29,337:
| Item | Value | Source |
|---|---|---|
| Fewer adders per mixer application that day | 231 to 206, 10.8 percent fewer | section 6.7 |
| Item derivations per unit of fabric that day | 1.121x (M1 gain) | section 6.7 |
| Hash rate of a recompute FPGA (items derived per hash, the `chip-model-v3` ops-per-hash attacker) that day | up to 12.1 percent above its ordinary day, an upper bound: the 128 dependent cache reads per hash and the shadow block are untouched by the draw, so the whole-hash gain is below the mixer's | `chip-model-v3.md` section 1 (ops per hash = 128 x 72 x 130); section 3 |
| Hash rate of the stored-dataset (f = 1) FPGA or chip that day | 0 (it derives no items per hash; the mixer is paid once in the daily build) | `funding.md` B2 rank 2 |
| Days a century at or over 1.1x | 12 (6 over, 6 at exactly 1.100x) | section 6.5 |
| Share of a century's hashes the M1 attacker gains | 12 / 36,525 x about 0.11 = 3.6e-5, 0.004 percent | arithmetic on the rows above |
| What one bitstream a day costs | one place-and-route of a large part: 42 to 160 minutes on a mid-size part (PRflow, FPT 2019, cited in spec 01 section 1.13), hours on a large one; on a rented 96-thread box (Hetzner AX162 class, about USD 0.35 per hour, approximate) under USD 3 per bitstream (approximate), and it compiles any time ahead because the calendar is public | spec 01 section 1.13; price approximate |
So the bitstream is cheap and the gain is 0.004 percent of a century for the slower of the two FPGA designs: nothing
a home miner on any card, a rig or a pool on any vendor or OS can see, and nothing that moves a day's difficulty.
What is being done about the M1 line: class v4 is not changed (it is the object on the live devnet's vote). The
rejection-and-redraw rule of section 8 is proposed to main for the next class, unless main reads the census as a
fault beyond the metric (this row does not: every class sits at its expectation and the worst day is an ordinary
draw). The rule costs one redraw on 5.6e-4 of days, changes no existing vector (day 20,729 has NAF sum 178; the first
day the rule would redraw is 22,633, about 5.2 years after genesis, section 6.5), and makes the M1 gate pass by
construction. `igneum-pow` is untouched by this row.
## 8. Proposed fix for the next class: a rejection-and-redraw rule on the MUL draw (for main's decision)
Shape, like the program acceptance rule 1.4.6 and `DeriveProgram::check`: draw the 16 `MUL`, test, and on rejection
continue the same stream with 16 fresh draws (so every later draw keeps its position only within an accepted block;
`RC` is drawn after the accepted `MUL` block). Tests, in order:
| Rule | Threshold | Rejection probability per candidate | What it closes |
|---|---|---|---|
| Sum of NAF weights of the 16 `MUL` at least 163 (M1 cost at least 211, gain at most 1.095x against the median 231) | `sum_i NAF(MUL_i) >= 163` | 5.64e-4 (`expect-231.log` cumulative at cost 210) | the M1 tail: no day over 1.1x by construction |
| Every `MUL` of NAF weight at least 4 | `NAF(MUL_i) >= 4` | 1.30e-5 per day | `MUL = 1`, `2^32 - 1`, `2^a +- 1`, `2^a +- 2^b +- 1`: the M2 words (hygiene; M2 already passes) |
| `ROT`: at least 4 distinct amounts (the `DISTINCT_ROTS_FLOOR` idea of `derive.rs`) | `distinct >= 4` | 3.07e-5 per day | the degenerate rotation draws (hygiene; 0 ops moved, diffusion fine at 2 applications) |
Total rejection about 6.1e-4 per day: one redraw every 4.5 years of chain time; `MAX_ATTEMPTS`-style exhaustion is
impossible in practice (64 rejections in a row at 6e-4 each). Class check to land with it: a unit test in `memhard.rs`
that plants a low-sum draw (stream seed chosen so the first MUL block fails) and asserts the redraw, plus this
harness re-run over 2^24 showing 0 days over 1.1x under M1 after the rule. The reproduction line for the finding
without the rule: `attack-f4 day --index 4819563 --median 231` (cost 197, 1.173x) and
`attack-f4 day --index 27952752 --median 231` (cost 194, 1.191x).
Consensus consequence: the rule changes the day-key-to-constants map on rejected days only, so it must land before the
freeze tag. In the chain's first 100 years the sum rule redraws 12 days (6 under 1.1x and 6 at exactly 1.100x,
section 6.5), the first of them 22,633, about 5.2 years after genesis; no pack cut for the devnet, the testnet or the
first five years of mainnet changes. The per-word rule redraws no day in the first 100 years (no word of NAF weight
under 4 in `census-100y.md`); the `ROT` rule redraws one, day 57,146 (2 distinct amounts, 99.7 years in).
## 9. What this row did not do
* It did not time the verifier per day beyond the confirmation row of 6.6: the verifier's code path is
value-independent (no branch on a drawn value), so op counts are the exact metric.
* It did not search optimal single-constant multiplication costs (not computable at 2^28 scale); NAF is the standard
canonical bound and the ratio between days is what the gate asks.
* It did not census the era draw (F7) or the spec's intent for the 64-bit seeding (F7); the fact is stated in section 1.

# F6: the verifier's worst case over 10^5 class v4 programs
Attack-pass row F6 (`docs/plans/cryptanalysis.md` 4.2; the record `docs/analysis/attack-pass-2026-10.md`), the box search.
The O-1.14 laptop relay run is not in this record (main runs it separately). Written 7 October 2026.
## Target
| Item | Value |
|---|---|
| Commit | `924288d1` on branch `attack-pass` (`igneum-pow` is byte-identical at the worktree HEAD `8e36faf6`: `git diff --stat 924288d1..HEAD -- igneum-pow` is empty) |
| Class | `--program-class v4`: generator 4 on `V4_CLASS` = `mx8+sh256x27` (`LoadClass::MX8` plus `ShadowClass { instrs: 256, reps: 27 }`), no era bytes (the same draw `igneum-pow bench --program-class v4 --seed S` makes) |
| Dataset | day `2026-10-03`, `Shape::for_class_day(V4_CLASS, 0)`: cache 2^26 words (256 MiB), mixer x8, dataset 2^28 words, memory-hard |
| Work per hash | 64 base instructions x 8 iterations (16 loads) plus 256 shadow instructions x 27 passes x 8 iterations = 55,296 shadow instructions, 101,192 counted ops at the 1.83 convention |
| Gate | 10 ms per 32-lane warp, cold, on the half-core proxy (plan 1.4 item 6; spec 01 section 1.9 and 1.11; `algorithm.md` 3.3 and 5.5) |
| Programs | 10^5 deterministic string seeds `attack-f6/0` to `attack-f6/99999` through the class v4 chain draw with its acceptance rule (5.22 percent needed a second or third attempt, max attempt 3) |
The era draw is not in the search: `generator.rs` draws the shadow block from `NONLOAD_WEIGHTS` with no era perturbation
(no `perturb` path exists in the code at this commit), and the era parameters change only the load addressing, not the op
counts. Every drawn program has exactly 48 non-load base instructions and 256 shadow instructions, so the verifier's cost
differs between programs only through the family mix (the per-family cost on the CPU) and the data.
## Known-failed shape
A drawn program whose verifier warp exceeds 10 ms cold on the half-core proxy. The acceptance rule (spec 1.4.6) bounds the
miner's side (distinctness, bias, saturation); nothing bounds the verifier's cost per program, and the half-core headroom
of the average program is 1.8 ms (`algorithm.md` 5.5), so a family mix that costs the CPU interpreter more than the average
could cross the gate.
## Harness
`tools/attack/f6-verifier/` (its own cargo crate, `igneum-pow` as a path dependency, the same release profile as the CLI:
opt-level 3, LTO, one codegen unit). It builds the day's dataset ONCE (`DatasetSource::new_shape`, 0.58 s on the box) and
swaps programs under it: `Epoch { program, dataset }` is only the pair, and `verify::hash_warp(&program, base, &dataset)`
takes both, so one dataset serves every program. The naive path (`igneum-pow bench` per seed) refills the cache every
time (370 ms) and would take 10 hours per core.
| Command | What it does |
|---|---|
| `attack-f6 scan --program-class v4 --count N --start S --threads T --cold-reps R --flush swap --out F` | program i = seed `attack-f6/<S+i>`; one CSV line per program: generation time, R timed warps (each after a flush), their min, the op counts by family for the base and the shadow block |
| `attack-f6 time (--program-class v4 \| --class dr736) --seeds-file F --cold-reps R --steady W --flush sweep` | the deep re-time: R cold warps (each after a 256 MiB write sweep, what the cache fill does before `bench`'s "single cold run"), max, median, min, a steady average of W warps, and `GATE 10 ms PASS/FAIL` on the max |
| `attack-f6 micro --program-class v4` | the genesis program with its shadow block rewritten to one family at a time against the same program with no shadow: the per-family cost of a shadow instruction (ranking weights only) |
| `attack-f6 load --program-class v4 --seconds 0` | hashes class v4 warps on the calling core until killed: the SMT sibling's load for the half-core proxy, the same class the 3.3 proxy ran on both siblings |
| `rank.py --scan ... --weights ... --column ... --top 50 --out-prefix P` | the proxy ranking (sum over families of weight x (8 x base count + 216 x shadow count)), the distribution (min, median, p99, p99.9, max with the seed), the worst-N lists, a no-intercept regression of time on the family counts |

`attack-f6 time ... --cold-reps 5 --steady 20 --flush sweep`, the gate applied to the max of the 5 cold warps
(`phase2a.log`). Lane-0 vectors equal the known ones (dr736 `e23d389f3eea0c83`, the Mac's).
| Case | Proxy | Cold max / median / min (ms) | Steady, avg of 20 | Known value (`algorithm.md` 3.3) | Verdict |
|---|---|---|---|---|---|
| known-fail, `--class dr736`, genesis seed | one core | 10.284 / 9.982 / 9.952 | 9.562 | 10.51 cold, 9.76 steady | FAIL (fired) |
| known-fail, `--class dr736`, genesis seed | half-core | 14.135 / 13.795 / 13.400 | 13.225 | 15.49 | FAIL (fired) |
| known-pass, `--program-class v4`, genesis seed | one core | 5.156 / 5.140 / 5.135 | 4.909 | 5.06 cold, 4.90 steady | PASS (fired) |
| known-pass, `--program-class v4`, genesis seed | half-core | 8.624 / 8.510 / 8.389 | 8.268 | 8.23 | PASS (fired) |
The harness reads the known-fail class over the gate and the known-pass class under it on both proxies, within 2 percent
of the 3.3 one-core numbers and within 9 percent on the half-core (the earlier half-core run loaded the sibling with
`igneum-pow bench` of the same class; this one hashes class v4 warps on it continuously).
## What one program can move (batch A, `micro`, core 40 solo)
The genesis class v4 program with no shadow block: 4.511 ms steady; with its drawn shadow: 4.920 ms. So the whole 55,296-
instruction shadow block costs 0.41 ms per warp on this core (7.4 us per 1,000 shadow instructions; `model.py` carries
7.0) and the base program with its 128 loads and 4,096 item derivations costs the other 4.5 ms. The verifier's cost is
92 percent dataset derivation (the x8 mixer, 8 dependent cache reads per item), which no drawn program changes: every
class v4 program has 16 loads and the acceptance rule's distinctness test keeps the items per warp near 4,096. The family
mix of the shadow can move at most a fraction of 0.41 ms. The per-family rewrite (the 256 shadow instructions all one
family) reads add 4.798, sub 4.703, xor 4.683, rotl 4.818, mad 4.805, shfl 5.042, rotr 5.160 ms per warp; the mul,
mulhi and or rows (0.97, 1.55, 1.13 ms) are degenerate (the registers collapse to 0 or all-ones, every lane then loads
the same item and the memory side vanishes) and are not ALU costs. Batch A's micro line printed its per-1,000 column
1,000x too small (ns per instruction); fixed in the source, the numbers above are the ms-per-warp column, which is right.
## Full one-core pass A (batch A, 50,000 programs, core 40 solo, one cold warp each after a program swap, `full-0.csv`)
617 s for 50,000 programs (12.3 ms each, 2.5 ms of it generation and acceptance). The per-family regression on the
50,000 timings (no intercept) gives 86 to 98 us per 1,000 executed instructions by family, R^2 0.001: the family mix
explains none of the program-to-program variation. Those regression weights (add 89.1, sub 87.7, mul 90.6, mulhi 98.4,
xor 89.6, or 86.0, rotl 89.4, rotr 86.3, mad 91.2, shfl 95.6) are the proxy weights used for the worst-50-by-proxy list.
| Pass A | n | min | median | p99 | p99.9 | max |
|---|---|---|---|---|---|---|
| all rows | 50,000 | 4.610 (`attack-f6/1278`) | 4.950 | 6.753 | 7.834 | 10.710 (`attack-f6/26705`) |
| rows outside the three disturbed blocks | 44,000 | 4.610 | 4.948 | 5.606 | 5.662 | 6.194 (`attack-f6/48484`) |
The rows over 6 ms sit in three 2,000-program blocks (26,000 to 27,999: 337 rows; 36,000 to 37,999: 300; 38,000 to
39,999: 294) and nowhere else (0 in each of the other 22 blocks); the neighbours of the 10.71 ms seed, unrelated programs,
all read 7.6 to 8.5 ms. `clock-2a.log` shows core 88 (the idle sibling of a solo run) at 3.8 GHz for stretches in those
minutes (08:21:25, 08:21:45, 08:22:05 to 08:22:25 UTC) and core 40 dipping to 3.68 GHz at 08:21:00: a foreign process
(the box's hands run outside the measure lock) sat on the sibling, which is the half-core condition, and those rows read
half-core numbers. They are not program properties and not numbers; the three blocks are re-scanned in batch B, and from
batch B on a per-second sampler logs every process whose last CPU was 40 or 88 (`clock-2b.log`, `clock-2c.log`) so a
disturbed row can be named.
## Batches B and C: queued, starved of the exclusive hold (state at 09:46 UTC)
Batch B (the second 50,000 of the full one-core pass, the re-scan of the three disturbed blocks, the worst 50 by proxy
and the worst 50 by phase-1 coarse time re-timed 10 cold reps each on both proxies) was queued with `flock -x -w 7200`
at 08:33:56 UTC and had not taken the file by 09:46 UTC. Linux `flock` gives a pending exclusive waiter no priority over
new shared takers; eight lanes re-take the file in chunks (17 to 38 shared holders at every reading, F2 spawning many
short ones, one F9 hold 33 minutes old at 09:06, over the 30-minute cap), so the file is never free. Left on the box:
`run2b-retry.sh` re-queues batch B up to four more times (2 h each); `run2c-auto.sh` waits for `BATCH B DONE`, builds the
batch C lists on the box (`mklists.py`: the worst 1,000 and worst 10 by the full one-core pass, pass A's three disturbed
blocks replaced by their re-scan) and queues batch C (the worst 1,000 on the half-core at 2 cold reps each, the worst 10
at 20 cold reps on both proxies). A marker sits beside the lock (`/srv/builds/_locks/measure.wanted-by-attack-f6`). When
they land, `timeparse.py --log phase2b.log --clock clock-2b.log` (and `2c`) prints the per-seed tables with the sampler's
foreign-process column, and this record is completed.
## Numbers so far, the gate, the verdict
| Quantity | Value | Where |
|---|---|---|
| Programs drawn and counted (phase 1) | 100,000 | `scan-0.csv`, `scan-50000.csv` |
| Programs timed cold on core 40 alone (one-core proxy) | 50,000 (44,000 clean, 6,000 in disturbed blocks awaiting the re-scan) | `full-0.csv` |
| One-core cold, clean rows: min / median / p99 / p99.9 / max | 4.610 / 4.948 / 5.606 / 5.662 / 6.194 ms (`attack-f6/48484`), single warps, not yet re-timed | `full-0.csv` |
| Genesis class v4, half-core, max of 5 cold | 8.624 ms | `phase2a.log` |
| Half-core over one-core, genesis class v4 | 1.67x (8.624 / 5.156) | `phase2a.log` |
| Programs timed on the half-core proxy | 1 (the genesis seed) | `phase2a.log` |
| Core 40 clock during every exclusive timing | 3,799.9 MHz (dips to 3,680 MHz only in the disturbed minutes) | `clock-2a.log` |
Gate line: the worst program under 10 ms cold on the half-core proxy. Not yet measured: no drawn program other than the
genesis seed has a half-core number, and the one-core worst (6.194 ms, a single warp with no sampler running) has not been
re-timed. Carried to the half-core at the genesis ratio it would read 6.19 x 1.67 = 10.3 ms, over the gate; carried at the
additive half-core cost of the genesis program (8.624 - 5.156 = 3.47 ms) it would read 9.66 ms, under it by 0.34 ms. The
2.5x bracket of `algorithm.md` 5.5 is between. Whether `attack-f6/48484` (and the other clean rows over 5.6 ms: 1 in 100
of the pass) is a program property or a short disturbance is what batch C's 20-rep re-time with the sampler decides;
the record says FINDING if its half-core cold max reads 10 ms or more.
Verdict: INCOMPLETE. 100,000 programs drawn and ranked, 50,000 timed on the one-core proxy, 0 of the worst re-timed on
the half-core proxy; the two firings fired; the box search's second half and the half-core re-times are queued and
starved of the exclusive hold.
## The ladder ceiling implied so far
`algorithm.md` 5.5 and `model.py --section ladder` set the ceiling from the half-core headroom at 12.1 us per 1,000 shadow
instructions, N = 101,192 + instructions x 1.83.
| Worst program on the half-core | Headroom to 10 ms | Shadow instructions it buys | Ceiling N (counted ops) |
|---|---|---|---|
| 8.23 ms (3.3's average, the published figure) | 1.77 ms | 146,000 | about 370,000 |
| 8.62 ms (genesis seed, this run's max of 5) | 1.38 ms | 114,000 | about 310,000 |
| 9.66 ms (48484 if the additive carry holds) | 0.34 ms | 28,000 | about 152,000 |
| 10.3 ms (48484 if the 1.67x carry holds) | none | 0 | below today's 101,192: the floor rung 100,000 is the ceiling |
The proposed genesis ladder {100,000; 130,000; 200,000; 330,000; 650,000; 1,000,000} already exceeds the 310,000 ceiling
at its fourth rung on the genesis program alone; on the worst program the ceiling could be the floor. This is the
ladder's own open question (plan 1.1, "ceiling set by the verifier"), and the number that sets it is the half-core
worst case still queued.
## Consequences per user tier (at the numbers measured so far; the model's table of 5.5 at 10 ms beside them)
| | At 8.62 ms (genesis, half-core max) | At 9.66 ms (worst, additive carry, unverified) | At 10.3 ms (worst, 1.67x carry, unverified) | Model at 10 ms |
|---|---|---|---|---|
| A node on a 2019-class laptop core at 1 bps | 0.9 percent of one core | 1.0 | 1.0 | 1 |
| At 10 bps (the Devnet 2 experiment) | 8.6 percent of one core | 9.7 | 10.3 | 10 |
| IBD over the 108,000-header pruning window, one core | 15.5 min | 17.4 | 18.5 | 18 |
| Header flood: invalid headers per second that saturate one core | 116 | 104 | 97 | 100 |
| A pool core verifying shares, shares per second per core | 116 | 104 | 97 | 100 |
What each tier does with it: a home miner (8, 12, 16, 24 or 32 GB card, any vendor, any OS) runs a node that spends about
1 percent of one CPU core on the hash at 1 bps whatever the drawn program, and 9 to 10 percent at 10 bps; the card is not
involved. A rig is the same per node. A pool verifying shares at 100 per second per core needs one core per 100 shares
per second at the worst program, 116 at the average: a pool that sized its share verification at the average loses 14
percent of its per-core headroom on the worst program, so pools size at 97 shares per second per core (the 10 ms figure)
and never at the average. A node under header flood holds at about 100 invalid headers per second per core on any
program, the M15 figure. The 2019-class core itself is still the half-core proxy until the O-1.14 laptop run lands
(main's lane).
What this lane does about it: completes batches B and C when the hold comes (automatic, on the box); if the worst
program reads 10 ms or more on the half-core proxy, the finding goes to main with the seed, the reproduction line
`igneum-pow bench --program-class v4 --seed <seed> --day 2026-10-03 --warps 50` on core 40 and the half-core, and the
proposed fix: an acceptance-rule bound on verifier cost (a per-program cost model over the family counts checked at
draw time, a redraw when it exceeds the bound, exactly as rule (c) redraws on bias) and the ladder's ceiling set from
the measured worst, not the average; `igneum-pow` is not edited by this lane.
## Batches B and C landed (7 October 2026, 13:5x UTC, cores 40 and 88 under the per-core lease)
The measure file was retired at 13:3x UTC and replaced by per-core leases; cores 40 and 88 were leased to this row
(`/srv/builds/_bin/lease cores 40,88 --owner attack-pass`), so the batches ran with nothing else on those cores while
builds continued on the rest of the box. Core 40's clock (`clock-2b.log`, `clock-2c.log`): median 3,799.9 MHz in both
batches, 954 of 958 and 57 of 63 samples at 3.7 GHz or more, the 1.5 GHz readings between runs.
| Batch | What | Programs | Reps | Worst program | Half-core cold max | Log |
|---|---|---|---|---|---|---|
| B | the second 50,000 of the one-core pass, then the worst 50 by proxy and the worst 50 by coarse time re-timed cold on both proxies | 200 re-timed | 10 | `attack-f6/87142` | 8.708 ms | `phase2b.log`, done 13:52:11Z |
| C | the worst 1,000 by the full one-core pass on the half-core, then the worst 10 at 20 cold reps on both proxies | 1,000 + 10 | 2, then 20 | `attack-f6/88521` (8.629), `attack-f6/15781` (8.414) | 8.629 ms | `phase2c.log`, done 13:57:45Z |
The one-core worst of the full pass (`attack-f6/48484`, 6.194 ms single warp) does not reach the half-core top ten:
its one-core reading was a short disturbance, as the batch C re-scan shows. Every program timed on the half-core
proxy reads under 9 ms.
## Gate line and verdict
Gate: the worst program under 10 ms cold on the half-core proxy (and on a 2019-class core: O-1.14, the i7-9700K row,
class v4 6.334 ms cold max). Result: the worst of 100,000 class v4 programs on the half-core proxy is 8.708 ms,
1.29 ms under the gate; the genesis program reads 8.624 on the same proxy, so the worst drawn program costs 1 percent
more than the genesis one and the distribution is tight (one-core clean rows 4.610 to 6.194 ms, p99 5.606).
Verdict: PASS. The two firings fired (dr736 FAIL at 15.49 ms half-core; class v4 genesis PASS at 8.62). Consequences
per tier: a 2019-class node verifying the worst class v4 program spends 0.9 percent of one core at 1 bps and 9 percent
at 10 bps on the pessimistic proxy; a header flood needs about 115 invalid headers a second to saturate one such
core; a pool verifies about 115 shares a second per core; IBD of 108,000 headers is about 16 minutes of one core.
Implied ladder ceiling on the half-core proxy from the worst program: 10 - 8.708 = 1.29 ms of headroom buys about
106,000 shadow instructions, N about 300,000 counted ops at the 1.83 convention (approximate), against 370,000
from the genesis program's headroom; the ladder's ceiling should be read from the worst program, not the genesis
one, so rung 2 (199,600) stays admissible and rung 3 (330,700) does not on this proxy.

# F7: the era-draw bias harness and the era-seed census
Attack-pass row F7 (`docs/plans/cryptanalysis.md` 4.2; the record `docs/analysis/attack-pass-2026-10.md`), both halves:
the fast-time re-roll harness (node lane) and the 2^20 era-seed census plus the 64-bit day-key check (hash lane).
Written 7 October 2026. Every number cites its log path on igneum-build-1.
## Target
| Item | Value |
|---|---|
| Commit | `924288d1` on branch `attack-pass` (`igneum-pow` is byte-identical at worktree HEAD `11b375a0`: `git diff --stat 924288d1..HEAD -- igneum-pow docs/spec infra/fast-time` is empty) |
| Spec | `docs/spec/01-lottery-hash.md` 1.13.1 (era seed and draw), 1.8.4 (the day-key mixer stream); `docs/spec/04-seeds-and-vdf.md` 4.4 (era seed pipeline) and 4.6 (T from a reference core); `docs/plans/era-layout.md` sections 1 and 8 (branch `ca2-era`); `docs/analysis/horizon/algorithm.md` 5.4 |
| Draw code | `igneum_pow::generator::era_draw` over `V3_ALLOWED = [1]` (the chain's path): the width draw (consumed, pinned at 4 bytes), the odd stride multiplier `M`, the rotation `R` in 1..31, the four interleave positions `pos` by partial Fisher-Yates |
| Day-key code | `igneum_pow::memhard::MixParams::with_shape`: `SplitMix64::new(K[0] \| (K[1] << 32))` draws ROT[0..7], MUL[0..15], RC[0..15]; `K = seed_words_from_bytes("igneum-day/" \|\| day_le64)` (node fork `consensus/pow/src/igneum.rs`, `bind::day_bytes`) |
| Node draw input (today) | `consensus/src/consensus/mod.rs` `seed_below`: `E_n` is the hash of the last selected-chain block below `15,552,000 n - 7,200` (era 0: genesis). The 1-hour VDF of spec 4.4 and the certified checkpoint it reads do NOT exist in the node (era-layout.md section 8, `proto-vdf` is a prototype) |
## Sub-row verdicts
| Sub-row | Verdict | Gate (plan 4.2 F7) |
|---|---|---|
| (a) re-roll harness | INCOMPLETE, with the written argument | no re-roll inside the publish window |
| (b) 2^20 era-seed census | PASS | no era class with gain over 1.1x at a fraction over 2^-20 |
| (c) 64-bit day-key seeding | PASS, within spec intent (one observation recorded) | the draw's input set as the spec states it |
## (a) The re-roll harness (node lane)
`tools/attack/f7-era/reroll.mjs`: a 3-node fast-time network (`infra/fast-time/override-60x.json` with
`skip_proof_of_work`, the `class-v4-signal.mjs` shape), own ports 29800 and up, own devnet suffix 980, own data dir
`/tmp/igneum-fast-time-attack-f7`. The node binary is the ladder fork `vendor/igneum-node-ladder` at `1591ee1d`
(`igneumd 2.1.0`, already built on the box; read-only). Two honest virtual miners share 1 block/s on nodes 0 and 1; the
adversary on node 2 holds a block `A` built on the tip at DAA score `S - 1` (the seed block sits there), optionally waits
a stub VDF of `--vdf-ms`, then publishes `A` to try to make its own block the epoch's seed block (the last selected-chain
block below the cut `S`). A re-roll succeeds when the epoch's reported seed becomes `hash(A)`.
The era cut `15,552,000 n - 7,200` is 180 days of DAA score away on every profile (`POW_ERA_BLOCKS` is a chain constant,
not an override field), so the harness attacks the EPOCH cut (`60 e - 10` at 60x), which runs the identical `seed_below`
derivation at a reachable score, one cut per minute. The harness's own era draw (JS) is checked byte-for-byte against the
Rust census at start: seed `b62532bc...` draws `M 558c0543 R 4 pos [0,1,2,3]` on both (log line "draw self-check ... OK").
Firings (both runs 6 cuts, box cores 36-37,84-85 under the shared measure lock):
| Run | `--vdf-ms` | Re-rolls to A | Gate | Harness | Log |
|---|---|---|---|---|---|
| known-pass | 0 (no delay, the stand-in) | 1 of 6 (epoch 11, seed = A) | FAIL | SOUND (fires) | `/srv/builds/igneum-wt-attack/attack-f7/reroll-knownpass.log` |
| known-fail | 5,000 (a delay past one block interval) | 0 of 6 | PASS | SOUND (silent) | `/srv/builds/igneum-wt-attack/attack-f7/reroll-knownfail.log` |
Both runs: 6 of 6 adversary blocks accepted, all three sinks agree, no reorg of the honest chain. The harness fires on the
known-pass and is silent on the known-fail, so it is trusted.
Written argument (the plan allows one for the VDF's assumptions; the VDF's own delay soundness belongs to the finality
review row of `funding.md`). The re-roll is possible ONLY when the adversary can evaluate the draw of a candidate input
inside the block publish window. Today the node has no VDF: `E_n` is a plain block hash, so the input of any candidate
block is known the instant the block is built, and the harness shows the last-block-before-the-cut is grindable with one
block of hash (1 of 6 cuts steered in fast time, `--vdf-ms 0`). With any delay past one honest block interval the
re-roll is gone (`--vdf-ms 5000`: 0 of 6). The design closes this with the 1-hour class-group VDF of spec 4.4: re-rolling
by withholding needs the 3,600 s VDF evaluated inside the 2 s window, a 1,800x evaluator, and spec 4.6's margin table
gives 300x as the horizon (`algorithm.md` 5.4; `sim/horizon/algorithm/model.py --section era`). The forge route needs
2/3 of the 30-day weight, 20 days of 100 percent hash (CLAUDE.md headline). The sub-row is INCOMPLETE because the harness
cannot demonstrate the real gate: the VDF and the certified checkpoint it reads are not in the node yet (era-layout.md
section 8 states this). What the harness DOES establish: the C_era cut rule with no delay is grindable, so the era draw's
soundness rests entirely on the VDF landing before the draw procedure is frozen, and the delay-soundness measurement is
owed to the finality lane.
## (b) The 2^20 era-seed census (hash lane)
`tools/attack/f7-era/` (a cargo crate with `igneum-pow` as a path dependency and an empty `[workspace]`; ELF built on the
box, sha256 `a87818d8...`). `attack-f7 census` runs `era_draw` over `V3_ALLOWED` on `2^n` seeds and classifies each draw;
`attack-f7 all` runs the plant known-fail case, the census, the spec-stream op-weight census and the day-key check.
Known-fail / known-pass of the classifier (planted parameters through a test hook in this crate; log
`/srv/builds/igneum-wt-attack/attack-f7/census-2p20.log`): every planted weak draw fires its flag (M = 1, M = 2^32-1,
M = 2^16+1, a naf-2 multiplier, an even M, R = 0, R = 32, pos linear, pos contiguous, pos not ascending) and a sound draw
(igneum-era-test/0) raises nothing. "Plant verdict: every planted case fired and the sound draw did not."
Census results (2^24 = 16,777,216 draws, the stronger run; `census-2p24.log`; the 2^20 run agrees, `census-2p20.log`):
| Class | Count (2^24) | Fraction | Expected (uniform) | Chip gain |
|---|---|---|---|---|
| M even (bijection failure) | 0 | 0 | 0 | finding if present: none |
| R out of 1..31 | 0 | 0 | 0 | finding if present: none |
| pos invalid (not 4 ascending) | 0 | 0 | 0 | finding if present: none |
| M = 1 (identity stride) | 0 | 0 | 4.66e-10 | 1.0034x |
| M = 2^32 - 1 | 0 | 0 | 4.66e-10 | 1.0030x |
| popcount(M) <= 2 | 1 | 5.96e-8 (2^-24) | 1.49e-8 | 1.0030x |
| popcount(M) <= 4 | 43 | 2.56e-6 (2^-18.6) | 2.33e-6 | 1.0022x |
| popcount(M) <= 6 | 1,626 | 9.69e-5 | 9.61e-5 | 1.0014x |
| popcount(M) <= 8 | 27,749 | 1.65e-3 | 1.66e-3 | 1.0007x |
| naf(M) <= 2 | 1 | 5.96e-8 | - | 1.0030x |
| naf(M) <= 3 | 18 | 1.07e-6 | - | 1.0026x |
| M = 2^k + 1 | 1 | 5.96e-8 | 1.44e-8 | 1.0030x |
| pos linear [0,1,2,3] | 9,257 | 5.52e-4 | 5.50e-4 | 1.0000x |
| pos contiguous | 120,054 | 7.16e-3 | 7.14e-3 | 1.0000x |
| pos in the low byte | 645,856 | 3.85e-2 | 3.85e-2 | 1.0000x |
The gain metric is the datapath energy a chip saves per hash against the base weights, over the hash's datapath energy
(19.5 nJ at 100,000 ops x 0.195 pJ, the N5 floor of `algorithm.md` 5.4 / `model.py --section era`). The stride multiply is
one of three address operations, run 128 times per hash (16 loads x 8 iterations); a low-weight `M` replaces the multiplier
with a few shift-adds, worth at most 128 x 0.52 pJ = 67 pJ, so M = 1 is the richest corner at 1.0034x. The rotation is a
wire mux and the interleave an address-line permute, 0 pJ on the modelled chip. No drawn parameter touches the memory
bound, the item derivation, the load count or N.
Gate: no class with gain over 1.1x at a fraction over 2^-20. The richest gain in the whole classifier is 1.0034x (M = 1),
and M = 1 did not occur in 2^24 draws (expected 4.66e-10). Every class at a fraction over 2^-20 has gain 1.0000x to
1.0007x. PASS on both counts.
Uniformity of the draw (2^24): stride rotation R over 1..31 chi-square 38.5 on 30 dof (max bucket deviation 2.07 sigma,
R = 0 or 32 seen 0 times); interleave pos 1,820 of 1,820 four-subsets seen, chi-square 1,775.7 on 1,819 dof (max deviation
3.63 sigma, 0 draws with a non-4-subset); M bit 0 always set (odd by construction), bits 1..31 each set in 0.500 of draws
(worst bit 1.81 sigma); the stride bijection never failed (0 even M). The era stream's own 64-bit seed (words 0 and 1) was
distinct on all 2^24 draws.
Op-weight corners (spec 1.13.1 first stream, implemented in `attack-f7 spec` from the spec text because `igneum-pow` does
not draw the op-weight perturbation at this commit; 2^20 draws, `census-2p20.log`): the ten non-load weights each
perturbed by -2..+2 and renormalised to 75 move the multiply share (mul+mad+mulhi, base 22 of 75) between 15 and 31. The
richest corner for a chip is 15/75 (0.152 pJ per op, -22 percent of the base datapath), seen once in 2^20; 16/75 at
3.22e-3. The GPU's energy moves the same way (its IMAD is the chain's own op), so the chip-against-GPU gain of every
weight corner is 1.0x, with 0 memory effect. Renormalised sums were 75 on every draw (0 failures). Fold rotations: a triple
all equal 2.13e-3, both triples all equal 1.91e-6, all six equal 0; uniform over 1..31, rotation 0 never drawn; a wire
mux, 1.0x.
## (c) The 64-bit seeding of the day-key stream (hash lane)
`attack-f7 days` over days 0..131,072 (`census-2p20.log`). The day key `K` is `seed_words_from_bytes("igneum-day/" ||
day_le64)`: a calendar function, no chain state. All 256 bits of `K` enter the cache fill (spec 1.8.3, `K[0..7]` in every
block input), so the dataset depends on the full key; the mixer-constant stream (ROT, MUL, RC) is seeded from `K[0] |
(K[1] << 32)`, 64 bits, which is the spec's stated intent (spec 1.8.4).
| Quantity | Value |
|---|---|
| Days the chain can have | about 65,745 in 180 years at 1 block/s (2^16.0) |
| Distinct 256-bit keys K over 2^17 days | 131,072 (all) |
| Distinct 64-bit stream seeds over 2^17 days | 131,072 (0 duplicates) |
| Distinct (ROT, MUL, RC) tuples over 2^17 days | 131,072 |
| Birthday bound on a 64-bit collision among 2^16 days | 2^(32 - 65) = 2^-33 |
The spec intends 64 bits for the mixer-constant draw, and the truncation is not a reduction of the draw space the firm
would flag: at most 2^16 days are ever drawn, each a distinct calendar day with a distinct 64-bit seed (0 collisions in
2^17), so no two days share a mixer. One observation, within spec intent and recorded for the written argument of
`funding.md` B5 rank 6: the mixer-constant stream has 64 bits of seed entropy, so at most 2^64 distinct daily mixers are
reachable (not the ~2^1,047 nominal); this is not exploitable (the days used are 2^16, all distinct) and whether any
reachable tuple is weak is the separate weak-day census of row F4.
## Consequences per tier
The era draw and the day-key seeding are protocol-wide and do not differ by card tier: the load width and load count are
pinned, so every era is equally memory-bound and no 8, 12, 16 or 24/32 GB card is advantaged or disadvantaged by any draw
(the measured six-era hash-rate spread is 1.3 percent on the RTX 5090, 3.2 on the RX 9070 XT, 0.8 on the M5 Max,
`algorithm.md` 5.4). No drawn era parameter or day key makes a chip cheaper against a GPU: the richest datapath corner is
1.0034x and is shared with the GPU. The one operational consequence is for the protocol, not a miner tier: the era draw's
grinding resistance is not yet demonstrable because the 1-hour VDF and its certified checkpoint are not in the node, so
the freeze of the draw procedure and the C_era cut rule must wait on the VDF landing and the finality lane's delay-
soundness measurement.
## Gate line
- (a) harness: INCOMPLETE. No re-roll with a one-block delay (known-fail 0 of 6); a re-roll with no delay (known-pass 1 of
6). The real gate (no re-roll inside the 2 s window) rests on the 1-hour VDF, which is not in the node; written argument
above.
- (b) census: PASS. No era class with gain over 1.1x at any fraction (richest 1.0034x, M = 1, absent in 2^24); the draw is
a bijection on every sample and uniform in R, pos and the M bits.
- (c) 64-bit seeding: PASS within spec intent. The spec intends 64 bits for the mixer stream; 2^16 days are all distinct;
the one observation (2^64 reachable mixers) is recorded, not a flaw.
What a failure moves (plan 4.2 F7): the draw procedure or the C_era cut rule; a redraw rule for the era stream. Nothing in
(b) or (c) moves them. (a) moves nothing in shipped code but gates the freeze of the draw procedure on the VDF.

# F8. Uniformity censuses of the class v4 derivation
Attack-pass row F8 (`docs/plans/cryptanalysis.md` section 4.2; the pass record `docs/analysis/attack-pass-2026-10.md`).
Run 7 October 2026, 08:13 to 09:3x UTC (09:13 to 10:3x UK) on igneum-build-1. Verdict: **FINDING** (AP-F8-1 below).
The line-index census is a PASS at its full sample size; the cross-hash item histogram is not uniform, and the cause
is in the base program, inside the acceptance rule's blind spot.
## 1. Target
| Item | Value |
|---|---|
| Commit | `igneum-pow` at 924288d1 (`attack-pass`); the box built HEAD b2a411d1, whose `igneum-pow` is byte-identical (`git diff --stat 924288d1 HEAD -- igneum-pow` is empty) |
| Class | `--program-class v4`: `V4_CLASS` = `mx8+sh256x27`, generator 4, mixer x8, the era layout drawn inside the class, the shadow block of 256 instructions x 27 reps |
| Line index | `proto-metal/MEMHARD.md` section 1.6: `a = s[0] AND 0x003fffff`, 4,194,304 lines of 64 B, 8 dependent reads per item (`memhard.rs` `derive_items_mask`, `cache.line_const(s[0])`) |
| Item index | `verify.rs` `load_index`: `y = rotl(x * M, R)`, the site's window `(y & (MASK >> k)) \| off`, then `Layout::split` removes the four interleave bits; 2^24 items at the 2^28-word dataset |
| Reads per hash | 128 loads (16 sites x 8 iterations), so up to 1,024 cache lines per hash and 32,768 per warp. The spec's analytic bound of 832 lines per hash (`docs/spec/01-lottery-hash.md` line 347, 104 loads x 8) predates generator 2's fixed 16 load slots; the current bound is 128 x 8 = 1,024 |
| Prior figures | `chip-model-v3.md` section 1: "median 128.00 distinct" items per hash (the 20,000-program census); `weak-program-census-2026-10-03.md` line 291: 127.7 distinct addresses per hash under the proposed generator |
| Day | the devnet pack's day, `bind::day_bytes(20730)` (2026-10-04), day 0 of the growth schedule: a 2^26-word cache, a 2^28-word dataset. Census 1 uses days 20730 to 20745 |
| Programs | p1 = the devnet epoch-0 derivation (epoch seed and era seed both the genesis hash `edc4fa84...fb07`, program id `c120d7963abdcd96`, attempt 0); p2 and p3 = chain-shaped seeds from tag strings (section 4), attempts 1 and 0 |
## 2. Method and harness
Harness: `tools/attack/f8-uniform/` (crate `attack-f8`, a path dependency on `igneum-pow`, nothing in the library
modified). Built on the box through `tools/build-remote.sh`: sha256 `590668...f913` for the firings of 2.1,
`ef8042...11b2` for sections 3, 4.1 and the first item runs (flat null, `log/c-*`, `log/d-*`), `890955...fbd3` for the
window-model runs and the seed census (`log/e-*`). The committed source carries one later label fix (the
"uniform-on-window" entropy reference in the per-site line is 16 - k_off bits; the 09:04 UTC logs print 16 - 2 k_off). Box scratch `/srv/builds/igneum-wt-attack/target-attack-f8/`
(the name `target-*` is what the box's checkout clean spared at the time; the fix at b92a5fd4 now also spares
`attack-*`). Every run: `nice -n 10 taskset -c 22-27,70-75`, 12 threads, under `flock -s /srv/builds/_locks/measure`
in chunks under 3 minutes each (the longest, phase D, under 25 minutes).
Two mirrors, each trusted only while it agrees with the library bit for bit:
| Mirror | What it records | Agreement check | Result |
|---|---|---|---|
| `derive_traced`: `memhard::derive_items_mask` instruction for instruction (`mixer`, `round_key_mult`, `cache.line` from the library), the line index of every round kept | 8 line indices per item | every item of every day also derived by the library's `derive_items` and compared on all 16 words | 0 mismatches on 268,435,456 items (section 3) and on 16,777,216 items per table build (section 4) |
| `Mirror::warp`: `verify::interpret_warp_init` for the class v4 op set, dataset words from a table of the day's 2^24 items, the item index and the source register of every load kept | 128 item indices per lane, the source value's saturation per position | the 32 hashes of warp 0 to 63 and of every 997th warp compared with `Epoch::hash_warp` | 0 mismatches on 95 warps per program (section 4) |
Three censuses:
1. `lines`: all 2^24 items of each of 16 consecutive day keys (2^28 item derivations, 2^31 line reads), the full 2^22-line
histogram per round and pooled, the 2^16-bucket histogram (64 lines, one chained segment per bucket), a uniform
SplitMix64 control of the same size.
2. `warps`: 10^6 nonces (31,250 warps) of each of three programs: distinct lines and items per hash and per warp, the
cross-hash item histogram, per-position diagnostics, an attribution pass from the hottest items back to the load
positions that read them.
3. `warps` at 2^26 nonces on p1: the one-epoch cross-hash item histogram at 512 expected reads per item.
The tests, defined before the runs:
- **6-sigma test**: the largest (and smallest) bucket of a histogram within 6 sigma of its expectation, sigma =
sqrt(expectation). The gate's bucket is the 64-line segment for lines and the 64-item bucket for items. The
full-resolution histograms are reported beside a uniform control of the same size, because at a small mean the
Poisson tail puts the maximum of 4 million bins above 6 sigma by chance (control at mean 8: +6.72 sigma; at mean
32: +5.83; at mean 512: +5.61).
- **Hot-set test** (F8's definition, written for F9's reuse): sort items by read count; S_f = the share of all reads
on the top-f fraction of items, for f in {0.1%, 0.5%, 1%}; E_f = the same share on a control of the same size drawn
from the design's own null (flat uniform for lines; the window-weighted null for items, section 4.2); the excess
X_f = S_f - E_f. **A hot set exists at f when X_f >= f**: after the chance excess is removed, the top f of items
capture at least one extra proportional share, which is what an on-die copy of f of the items would have to win to
matter. X_f / f is printed as the gain in proportional shares. The acceptance-style form of the same metric (for
rule (c)'s 2,048 evaluations): per load position, the largest count of one masked address, and the count of
saturated (0 or 2^32 - 1) source values.
### 2.1 The harness fires (known-fail and known-pass)
| Plant | What it does | 6-sigma test | Hot-set test | Log |
|---|---|---|---|---|
| `quarter-lines` | line index masked to a quarter of its range | buckets64 largest +75.97 sigma (2,231 at mean 512), smallest -22.63: FLAGGED | X_1% = +3.54% (S 5.60% vs control 2.06%), X/f = 3.5 at every f: FLAGGED | `log/a1-lines-quarter.log` |
| `half-lines` | line index masked to a half | buckets64 largest +29.26 sigma: FLAGGED | X_1% = +1.25%, X/f = 1.25: FLAGGED | `log/a2-lines-half.log` |
| `const-item` | one constant item at the first load site (1/16 of reads) | items buckets64 largest +92,682 sigma: FLAGGED | X_0.1% = +6.38%, X/f = 63.8: FLAGGED | `log/a4-warps-const-item.log` |
| none, 2^22 items, one day | the real derivation at a small size | buckets64 largest +4.42 sigma, smallest -4.51: within 6 sigma (control +4.33) | X_f = -0.0004%, -0.0006%, -0.0010%: clear | `log/a3-lines-pass-small.log` |
Both tests fire on every plant and neither fires on the real line derivation. Log paths are under
`/srv/builds/igneum-wt-attack/target-attack-f8/`.
## 3. Census 1: the line index over 2^28 derivations (PASS)
Sample reached: 16 days x 2^24 items = 268,435,456 item derivations, 2,147,483,648 line reads into 4,194,304 lines
(512 expected per line, 32,768 per 64-line segment). Mirror mismatches against `derive_items`: 0 of 268,435,456.
Log: `log/b-lines-16days.log`; histograms `out/lines-d20730-n16-i24-none-buckets64.txt` (65,536 rows) and
`out/lines-d20730-n16-i24-none-full.u32le` (4,194,304 x u32).
| Histogram | Bins | Expected | Largest | Sigma | Smallest | Sigma | chi2/dof | Top 1% share |
|---|---|---|---|---|---|---|---|---|
| Pooled, 64-line buckets (the gate) | 65,536 | 32,768 | 33,645 | +4.84 | 31,998 | -4.25 | 1.00226 | 1.01427% |
| Pooled, full 2^22 lines | 4,194,304 | 512 | 639 | +5.61 | 402 | -4.86 | 0.99937 | 1.11979% |
| Control, 64-line buckets | 65,536 | 32,768 | 33,524 | +4.18 | 31,960 | -4.46 | 0.99930 | 1.01426% |
| Control, full 2^22 lines | 4,194,304 | 512 | 639 | +5.61 | 408 | -4.60 | 0.99952 | 1.11956% |
| Per round 0 to 7, full, pooled (64 per line) | 4,194,304 | 64 | 107 to 113 | +5.38 to +6.12 | 26 to 29 | -4.75 to -4.38 | 0.99855 to 1.00062 | 1.3483% to 1.3488% |
| One day (20730), 64-line buckets | 65,536 | 2,048 | 2,291 | +5.37 | 1,859 | -4.18 | 0.99985 | 1.05826% |
| One day, control, 64-line buckets | 65,536 | 2,048 | 2,250 | +4.46 | 1,874 | -3.84 | 1.00377 | 1.05901% |
Per day, the gate bucket's largest value ran +4.00 to +5.37 sigma on all 16 days (control +4.46), every day within
6 sigma. Hot-set test on the pooled lines: X_0.1% = -0.00002%, X_0.5% = +0.00010%, X_1% = +0.00023% (X/f under
0.0003): clear. Round 0, whose input is the sequential item index through the init `t * MUL[i] + RC[i]` and eight
mixer applications, is as flat as rounds 1 to 7 (chi2/dof 0.99926; its +5.50 sigma maximum is below the control's
+5.61 at the pooled size). Round 5's +6.12 sigma at mean 64 is one bin of 4 million at a Poisson tail where the
control at mean 8 reached +6.72; its chi2/dof is 0.99855.
Gate line: the largest bucket is within 6 sigma of uniform (+4.84 on the 64-line buckets, +5.61 on the full 2^22
lines, both at or below the control), chi2/dof 0.99937, no hot set. **PASS at 2^28 derivations.**
## 4. Census 2 and 3: distinct lines per hash and warp, and the cross-hash item histogram
Setup per program: the day's 16,777,216 items derived once into a table with their 8 lines (6 to 9 s on 12 threads,
0 mismatches against `derive_items` on every item), then the warps interpreted from the table at 2.7 to 3.2 ms per
warp per thread. Logs: `log/c-warps-p{1,2,3}-1e6.log` (first run, flat null) and `log/e-warps-p{1,2,3}-1e6.log`
(windowed null, section 4.2); distributions `out/warps-<program>-d20730-n1000000-none-distinct.txt`, item histograms
`...-items.u32le` (16,777,216 x u32), per-position tables `...-positions.txt`.
### 4.1 Distinct lines and items per hash and per warp (10^6 nonces each)
| Program | Epoch seed / era seed | Lines per hash min / p1 / median / max / mean | Items per hash min / median / mean | Lines per warp min / median / max / mean | Items per warp min / median / mean |
|---|---|---|---|---|---|
| p1 `c120d7963abdcd96` (devnet epoch 0) | genesis / genesis | 1,008 / 1,023 / 1,024 / 1,024 / 1,023.867 | 126 / 128 / 127.9989 | 32,579 / 32,636 / 32,680 / 32,635.84 | 4,090 / 4,096 / 4,095.41 |
| p2 `82f0696f823e9c65` | `59cef1aa...bfdfa` / `9cba001f...1f69` | 1,014 / 1,023 / 1,024 / 1,024 / 1,023.871 | 127 / 128 / 127.9995 | 32,580 / 32,637 / 32,684 / 32,636.08 | 4,091 / 4,096 / 4,095.48 |
| p3 `e282eed7d47e425e` | `c54e2ddd...c95d` / `1b04f607...b58a` | 999 / 1,016 / 1,024 / 1,024 / 1,023.600 | 125 / 128 / 127.9656 | 32,276 / 32,481 / 32,601 / 32,480.32 | 4,050 / 4,076 / 4,075.85 |
| Uniform expectation | | 1,023.875 of 1,024 | 127.9995 of 128 | 32,640.3 of 32,768 | 4,095.50 of 4,096 |
Per hash, every program reads its 128 items and 1,024 lines as the design intends (p1 and p2 at the uniform
expectation; p3 a shade under, 127.97 items, which is the same site-15 effect as the finding below: the saturated
site repeats an item inside a hash 3 times in 100). Per warp, 32 lanes read 32,636 distinct lines of 2^22, a 2 MiB
working set of cache lines and 256 KiB of dataset items, within 0.01% of uniform on p1 and p2.
### 4.2 The cross-hash item histogram and the window layer
The era layout's window layer (`docs/plans/era-layout.md` section 1.4, layer 8) makes each load site read an
aligned half or quarter of the dataset with probability 2/3. The per-site item distribution is therefore not flat by
design (the diagnostic's "worst bit" reads P(1) = 1.0000 or 0.0000 at every windowed site: the fixed top bits), and
the summed item histogram has density steps between quarters. For p1 the 16 windows (site:shrink:offset
`7:2:1 8:1:1 9:1:1 10:1:1 11:0:0 13:1:1 29:0:0 30:2:2 31:1:1 44:1:1 46:2:0 47:0:0 52:0:0 56:0:0 58:2:0 63:1:1`) give
expected reads per item by quarter of 3.25 : 2.25 : 5.75 : 4.75 in sixteenths of the flat value. Against a flat
uniform the 64-item buckets of p2 (a program without the finding) read +10.03 and -9.06 sigma, which is the window
layer and not a flaw. The item tests are therefore judged against the **window-weighted null**: the expected count of
every item from the program's 16 windows, and a control that draws each read from a uniformly chosen site's window.
A chip gains nothing from the window steps: the union of the windows is the whole dataset every hour (era-layout.md
section 7), the floor window is 2^26 words (256 MiB), and which quarter is dense changes with the program.
#### The window model (reproducible by the firms)
For load site s with window draw `(k_s, o_s)` at the 2^28-word dataset: `k = min(k_s, 28 - 26)`, the word window is
`[o_s << (28 - k), (o_s + 1) << (28 - k))`; the item window is `[o_s << (24 - k), (o_s + 1) << (24 - k))` of
`2^(24 - k)` items (the four interleave positions all lie below bit 16, so the top bits of the word index are the top
bits of the item index). The expected reads per item is `E[t] = sum over sites s with t in window_s of N x 8 / 2^(24 - k_s)`
for N nonces (8 iterations per site), a density constant on each quarter of the item space. The windowed control draws
each of the N x 128 reads as (site = read index mod 16, item uniform on that site's window). Both controls are drawn from
SplitMix64 with a fixed seed. The tests on items are run against E[t] (chi-square, sigma of the largest and smallest
64-item bucket) and against the windowed control (the top-f shares); the flat uniform numbers are kept beside them as
what an auditor sees first.
#### Results, 10^6 nonces per program, 128,000,000 reads (`log/e-warps-p{1,2,3}-1e6.log`)

p2 is what the class is designed to be: against the window model its largest bucket is +4.59 sigma (the control +4.64),
chi2/dof 1.006, the top 0.1% of items hold 1.029x their window-model share, and the flat-control ratio of 1.118x is
the window layer. p1 and p3 are the finding (section 5). The one-epoch histogram at 2^26 nonces (8,589,934,592 reads,
512 per item, `log/d-warps-p1-2e26.log`, flat null): p1's top 0.1% hold 0.5199% of reads against 0.1152% flat
control (X/f 4.05), the top 1% 2.4946% against 1.1198% (X/f 1.37), item 0xca5b92 78,479 reads at a mean of 512, and
site 15 feeds 6.37% of its reads into the top 0.1% in each of the 8 iterations; the excess grows with N as the
control's chance excess shrinks, which is the signature of a structural skew. Distinct lines and items per hash and
per warp at 2^26 nonces: 1,023.866 / 127.9989 / 32,635.6 / 4,095.41, unchanged from 10^6.
## 5. AP-F8-1: a saturated load source makes a cross-hash hot set (FINDING)
**What**: an accepted class v4 program can read one load site from a register whose last writes after its last
injecting write are `or` (and, mildly, `mul`), so the site's address has fewer than 32 bits of entropy across nonces
and the same items are read by many hashes. The per-hash figures (128 distinct items, 1,024 lines) stay intact; the
cross-hash item histogram does not. It is not the window layer (p2 shows the window layer alone is clean against its
model) and not the shadow block (iteration 0's load, which runs before any shadow block, is as hot as iterations 1 to
7: p1 6.372% vs 6.371% to 6.378%; p3 71.9% vs 72.4% to 72.6%).
**Where it hides from rule (c)** (`accept.rs`, 2,048 evaluations of the base program): the tests are constant bits
in FINAL register values, one address in ALL 32 lanes of a unit, saturated FINAL values, output-bit bias, and distinct
addresses WITHIN a hash. A site whose address is concentrated across hashes but refreshed before the end of the
iteration passes every one. Rule (a) accepts any write, `or` included, as the refresh between two loads from the same
register (`check_stale_loads`); `Op::injects` (add, sub, xor, mad, shfl, load) is only used by rule (b), once per
register per program.
**The index derivation at the hot site** (the "writers back to the last injecting one" lines of `log/e-warps-p*.log`):
| Program | Hot site | Source | Writes after the last injecting write | Site's reads into the top 0.1% of items (flat expectation) | Index entropy, 256-item buckets (uniform on window) | Saturated source (x = 0 or 2^32 - 1) | Most repeated address at one position in 2,048 evaluations (uniform: 1 to 2) |
|---|---|---|---|---|---|---|---|
| p3 | site 15, instr 62 | r5 | `load@17` then `or@19`, `or@30` | 72.43% (0.10%) | 13.411 bits (16) | 1.368% | 44 of 2,048; 32 saturated |
| p1 | site 15, instr 63 | r6 | `add@51` then `rotl@53`, `or@61` | 6.93% (0.11%) | 14.985 bits (15) | 0.005% | 2 of 2,048; 0 saturated |
| p2 (clean) | every site | | injecting, or bijective (`rotl`), or `mul`/`mulhi` | 0.41% to 0.97% (0.20%; the window densities) | 13.999 / 14.997 / 15.994 bits (14 / 15 / 16) | 0.000% | 2 of 2,048; 0 saturated |
In p3 two `or`s on r5 after its load make the source 1 with probability 7/8 per bit; x = 2^32 - 1 in 1.37% of
evaluations and the images of the near-saturated values under the stride (`y = rotl(x * M, R)`, 256 x-values per
item) pile onto a few items: 0xffdf69 takes 213,913 of the site's 8,000,000 reads (2.67%), the top 0.1% of items
72.4%, and 4.6% of ALL reads of the hash land on 0.1% of the items. In p1 one `or` after `rotl(add)` gives 3/4 per bit
on the ORed positions: no saturation to speak of (0.005%), but 6.9% of the site's reads on 0.11% of the items (the
hot items share the low 20 bits `5b92`: 0xca5b92, 0x8a5b92, 0xaa5b92, 0xba5b92, 0x825b92, 0xe65b92, 0x985b92), a
2.6x proportional excess at f = 0.1%. p2's `mul` sites (10, 13: `mul` after a load or a shuffle) read 0.65% and 0.70%
into the top 0.1% against 0.41% and 0.48% for their window class (an even multiplier zeroes low bits; the hot items
0xd6a680, 0xe44400, 0xd25600 end in zero bits), a mild effect that the window-model ratio (1.029x) absorbs.
**How common** (the seed census, 64 chain-shaped programs p4 to p67, 262,144 nonces each, `log/e-seed-census-4-67.log`,
`out/seed-census-d20730-n262144-p4-67.txt`): CENSUS-LINE
**Reproduction**: `attack-f8 warps --program 3 --nonces 1000000 --diag 1` (or `--program 1`); the acceptance-style
numbers come from the same run's "acceptance-style" line. The program is `Epoch::chain_program(epoch_seed, Some(era),
ProgramClass::V4, label)` with the seeds of section 4.1.
**Proposed fix** (not applied; `igneum-pow` untouched, the Counter ASIC lane re-gates on `ca3-v4-uniform` with this
harness):
1. Rule (a'), static: between the last injecting write of a load's source register and the load (cyclically), no
`or` and no `mul` writes that register; `rotl`, `rotr` and `mulhi` may (bijective, or measured flat: p2 site 15
reads `mulhi` after `add` at 1.00x). This rejects p1 and p3 at draw time and costs nothing at run time. Programs
rejected are redrawn as today (`MAX_ATTEMPTS` 32); the census gives the rejection rate.
2. Rule (c'), dynamic, the same 2,048 evaluations: no load site reads a saturated source (0 or 2^32 - 1) in more
than 2 evaluations, and no address repeats more than 4 times at one position (uniform expectation 1 to 2; p3 shows
44 and 32). This catches the strong class only; p1's class needs about 2^16 evaluations to show at a site (65,536
nonces: largest item count 67 at a mean of 0.5), so (a') is the rule that closes it and (c') is the check that
fails loudly if (a') is ever loosened.
3. Packs re-cut for the seeds the new rule rejects (the devnet epoch-0 program p1 is one of them: its site 15 is
`or@61`), with the gate pack ids re-pinned; the chain's own epochs redraw automatically.
**Reuse for F9**: the hot-set metric (section 2) on the per-program item histogram at 2^18 nonces, and the
acceptance-style pair (most repeated address at a position, saturated sources at a position) at 2,048 evaluations,
are both emitted by `warps --programs a..b`; a header-grinding search that steers a program to a hot set would show as
ratio-to-window-model above 1.2x at f = 0.1%.
## 6. Consequences per tier
| Number | What it means | Per tier |
|---|---|---|
| Line index uniform at 2^28 derivations (largest segment +4.84 sigma, chi2/dof 0.99937) | the 256 MiB cache has no hot segment: a chip or a card cannot serve the 8 dependent reads of an item from a cache smaller than the whole 256 MiB (the floor window of era-layout.md) | no change for any card; the verifier's cache stays 256 MiB in RAM on every node |
| Distinct lines per hash 1,023.87 of 1,024, items 127.999 of 128 (p1, p2); per warp 32,636 lines, 4,095 items | the per-hash working set is 64 KiB of cache lines and 8 KiB of items, per warp 2 MiB of lines and 256 KiB of items; the item-derivation chip's "128 items per hash" input (`chip-model-v3.md`) stands | the 8 GB card and up: unchanged; the recompute chip pays 128 derivations per hash, as modelled |
| p3-class programs: 4.6% of all dataset reads on 0.1% of items (1 MiB of a 1 GiB dataset); p1-class: 0.59% on 0.11% | a stored-dataset chip with 1 MiB of on-die SRAM serves 4.6% of its reads without touching DRAM on such an epoch; a GPU's L2 (96 MiB on the 5090, 64 MB Infinity Cache on the 9070 XT, vendor figures) holds the same 1 MiB, so both sides gain the same 4.6% of reads and the chip's edge from it is about 0 (the per-joule edge of `evidence.md` row 17 is a DRAM-read figure; a 4.6% read saving on both sides moves it by under 5% on such epochs). The recompute chip (f = 0, SRAM cache) caches the derived hot items and skips up to 4.6% of its 128 derivations per hash on such epochs, a 4.8% rate gain on those epochs only | home cards 8 to 32 GB, rigs, pools: no action; a few percent of epochs run a few percent faster for everyone with an L2. The verifier: `MemhardCpu::fetch` dedupes within a fetch only, so no change. The chip model: the headline 2.1x at k = 1 moves by under 5% on affected epochs and 0 on others; the fix below returns it to 0 everywhere |
| The acceptance rule's blind spot (cross-hash concentration at one site) | a program class property, not a day or era property: the same seed is hot on every day and under every era, so a chip or a pool that selects epochs cannot gain more than the epoch's own 4.6%; but the public claim "the item map is uniform per program up to the window layer" is false for the affected fraction of seeds until rule (a') lands | the fix is a generator rule plus packs re-cut: a class change under the 95% signalling rule if it lands after the flip, a plain re-cut if it lands in the class v4 cut itself (the lane's call) |
## 7. Gate line and verdict
| Gate (plan 4.2 F8, the same as 1.4 (4)) | Result | Status |
|---|---|---|
| The largest bucket within 6 sigma of uniform on the stated sample sizes (line index, 2^28 derivations) | +4.84 sigma on 64-line segments, +5.61 on 2^22 lines (control +4.18 / +5.61), chi2/dof 0.99937 | PASS |
| The item distribution within 6 sigma of uniform (against the window model, the design's own null) | p2 +4.59 sigma (control +4.64); p1 +45.77; p3 +12,245.66 | FAIL on p1 and p3 |
| No hot set under 1% of items among passing seeds (10^6 nonces on three programs; the 64-seed census at 2^18) | p2 none; p1 top 0.1% at 1.888x the window model (2.247x flat), X/f 2.57; p3 16.46x (18.92x flat), X/f 43.2; census: 31 of 64 seeds over 1.2x of the window model, 23 with a hot item | FAIL |
| The Counter ASIC lane's record gate: top 0.1% within 1.2x of the window-model control on every seed | p2 1.029x; p1 1.888x; p3 16.46x; census: 31 of 64 seeds over 1.2x (median 1.17x, p90 2.70x, max 13.09x on p31) | FAIL |
**Verdict: FINDING (AP-F8-1).** The line index passes at 2^28 derivations. The cross-hash item histogram fails
the hot-set gate on 2 of the 3 named programs (one of them the live devnet epoch-0 program) and on 31 of 64 seeds (48 percent) of of
the 64-seed census, from `or` (and mildly `mul`) writes on a load's source register after its last injecting write,
outside every test of rule (c). What it moves: not the mask or the fold (the derivation is uniform) but the
acceptance rule, (a') and (c') above, and the packs re-cut. Ownership: the Counter ASIC lane (generator and rule),
re-gated with this harness on the fixed branch; the row reads FIXED-AND-PASSED when every seed of the census passes
both the hot-set test and the 1.2x gate under the new rule.
Sample sizes reached: 2^28 derivations (lines); 10^6 nonces on three programs (distinct lines, hot set); one epoch at
2^26 nonces (cross-hash histogram); 64 seeds at 2^18 nonces (the census).
Times UTC in the logs; the runs ran 08:13 to 09:2x UTC on 7 October 2026 (09:13 to 10:2x UK).

# F9: acceptance edges, the hot-set search, header grinding
Attack-pass row F9 of `docs/plans/cryptanalysis.md` section 4.2 (record: `docs/analysis/attack-pass-2026-10.md`).
Sub-agent attack-f9, 7 October 2026. Status: IN PROGRESS (rewritten as each run lands; the numbers below are the
ones already final, each with its log).
## Target
| Item | Value |
|---|---|
| Commit | 924288d1 (branch attack-pass, worktree igneum-wt-attack) |
| Generator | 4, class v4 `mx8+sh256x27` composed with the era draw (`LoadClass::era(V4_CLASS, E, [4 bytes])`), era seed E = the devnet epoch-0 seed `edc4fa84...fb07` (`proto-cuda/packs-ca3-v4/v4-devnet-epoch0/seeds.txt`) |
| Rule | `igneum-pow/src/accept.rs`: (a) stale load sources, (b) injecting writes, (c) the 2,048-evaluation dynamic test on the closed-form stand-in `dataset_elem` at 2^28 words with init words = seed words; redraw on rejection up to 32 attempts |
| Header binding | `igneum-pow/src/bind.rs`: init words `I = seed_words_from_bytes("igneum-block/" \|\| H \|\| nonce_hi_le32)`, one `I` per 32-lane warp, the lane nonce in the low 32 bits |
| Memory-hard dataset for the edges | the devnet day 20730 (`day_seed_hex 69676e65756d2d6461792ffa50000000000000`), class v4 shape (mixer x8, cache 2^26 words, dataset 2^28 words), `Epoch::chain_dataset_day` |
| Card | RunPod RTX 5090 (170 SMs, 32,120 MiB, driver 570.195.03, CUDA 12.8.1), pack `v4-devnet-epoch0` built there with `nvcc -O3 -arch=sm_120` |
## Known-failed shape
A seed grind that steers a program to a hot cache set for DRAM locality, or an edge where the closed-form stand-in
disagrees with the live verifier in the attacker's favour.
## Gate
Zero passing programs with a hot set under 1 percent of items among 10^6 seeds; the grinding gain under 1 percent of
rate at any search cost. What a failure moves: the closed-form stand-in replaced by the live verdict at the edges; a
locality term in rule (c).
## Harness
`tools/attack/f9-grind/` (crate `attack-f9`, `igneum-pow` as a path dependency, nothing in igneum-pow edited; built
on igneum-build-1 through `tools/build-remote.sh`; the binary on the box at
`/srv/builds/igneum-wt-attack/tools/attack/f9-grind/target/release/attack-f9`):
| Sub-command | What it does |
|---|---|
| `selftest` | the firings listed below |
| `edges` | sub-row (a): every candidate of every seed through the re-implemented dynamic test twice, closed form and memory-hard, every metric of rule (c) measured to the end (no early abort) with its margin; the attempts continue until both stand-ins have accepted, so the chosen program under each is known |
| `hotset` | sub-row (b): the seed's accepted program, its 2,048 x 128 address record under the acceptance init and under a block init; per site the nonce-independent address bits, the distinct addresses and the most-read address; the histogram at bucket scales 2^8 to 2^24 words against a window-aware Poisson expectation (the era windows send a site to the dataset, a half or a quarter of it) with a Bonferroni tail; the taint count of init-determined loads |
| `inspect` | one seed's program with every site that repeats an address |
| `grind`, `table-random` | sub-row (c), CPU side: the init-determined load sites of the devnet epoch-0 program, the per-warp search over K nonce_hi values for the fewest distinct 128 B lines inside those load instructions (`--mode intra`, what the coalescer merges) or across them (`lines`, `pages`), the search cost per hit, and the per-warp init tables the card reads |
| `reference` | the 64 bound hashes the card's known-pass compares against; the file used on the pod came from the pre-built `igneum-pow hash-bound` instead (`ref.txt`, sha256 e831458a...) |
| `summarise.py` | the census summaries quoted below |
`tools/attack/f9-grind/pod/` (the card): `make-variants.py` copies the pack's `kernel_bound.cu` into five kernels
(per-warp init table; the five init-determined loads broadcast to lane 0's address; every load broadcast; the first
such load broadcast; lane 1 reading lane 0's address at the first such load), `f9-host.cu` fills the cache and dataset
with the pack's own kernels, checks them against `vectors.h`, checks the bound hash against the reference, checks the
per-warp kernel on an all-equal table against the honest kernel, then times the eight variants in interleaved rounds;
`run.sh` builds on the pod, samples `nvidia-smi` once a second and joins the samples to the phases (`join-power.py`).
Hot-set metric (F8's record `docs/analysis/attack-pass/f8-uniform.md` did not exist when this harness was written, so
the metric is defined here). Strict reading, "any hot bucket": a site with 7 or more nonce-independent address bits
(support at most 2^21 of 2^28 words, 0.78 percent of items; the window's own fixed bits not counted), or any bucket
of at most 2^20 words (0.39 percent of the dataset) at scales 2^8, 2^12, 2^16, 2^20 whose count has a Poisson tail
against its window-aware expectation under 10^-6 after the Bonferroni correction. Gate reading, "flagged": the reads
above expectation in those hot buckets (the hot share, what a cache of the hot set saves at most) reach 1 percent of
the program's reads, or a site has 7 constant bits.
## Firings (the harness is trusted only after these)
Log: `/srv/builds/igneum-wt-attack/attack-f9/selftest.log` (copy in the Mac scratchpad `f9-box/selftest.log`).
| Check | Known-pass | Known-fail | Result |
|---|---|---|---|
| 1 | the re-implemented dynamic test against `accept::check` on 300 class v4 candidates: every verdict, the first failing condition, and distinct, saturated and bias of every accepted report equal | | PASS (300 candidates, 16 rejected by accept, all equal, 1.5 s) |
| 2 | both stand-ins forced equal (closed form twice) on 200 candidates | | PASS, 0 disagreements |
| 3 | | the memory-hard stand-in gives different words: distinct 262,117 against 262,106, bias 56 against 64 on one program | PASS (they differ) |
| 4 | 50 accepted programs, none with 7 constant bits (worst 0) | 50 plants (an accepted program rewritten to `xor a,a; add a,a,256; mulhi a,b` before a load from `a`, 48 of 50 still pass rule (c)) all flagged (support 256 words, site distinct 255 or 256) | PASS for the plant; 4 of the 50 clean programs have a hot bucket (sub-row (b): that is the finding, not a harness fault) |
| 5 | taint on the devnet epoch-0 program against the hand reading of `kernel_bound.cu`: loads 7, 8, 9, 10 read r7, r4, r2, r0 (no load before them); load 31 reads r5 = r5 x r4 from instruction 12, both untouched by any load; loads 11, 13, 29, 30 read r1, r6, r4, r3, each written by an earlier load or by `mad` from r7 after load 10 | | PASS: sites (0,7) (0,8) (0,9) (0,10) (0,31) |
| card 1 | cache FNV 448274a57f508cbc, dataset head, last word and 64 samples, the 96 pack vectors | | PASS (`pod log/host.log`) |
| card 2 | the bound hash against the 64 reference lines of `igneum-pow hash-bound` (nonce_hi 0, prehash 000102..1f) | | PASS, 0 wrong |
| card 3 | the per-warp kernel on an all-equal table equals the honest kernel on 64 lanes | the two-init table: warp 0 equal, warp 1 differs in 32 of 32 lanes | PASS both |
| card 4 | | the forced kernels change the hash: forced4 64 of 64 lanes, forcedall 64, forced1 64, pair 64 | PASS (they fire) |
| card 5 | | a deliberately locality-maximising choice shows a measurable change: `pair` (one line of 4,096 saved per warp) +0.21 percent, `forced1` (31 lines) +6.8 percent, `forced4` (155 lines) +43.3 percent, `forcedall` +181.9 percent in the smoke run | PASS (measurable from one saved line up) |
## Sub-row (a): the edges
Run: `attack-f9 edges` over seeds `igneum-f9/0` to `igneum-f9/99999`, 8 threads on cores 28-31,76-79 in 10,000-seed
chunks under a shared hold of the box measure lock (`run-census.sh`); output `edges.part*.tsv`, summary by
`summarise.py edges`. The first 20,000 seeds (parts 0 and 1) are summarised here; the full 10^5 replaces this table
when the run ends.
| Quantity | First 20,000 seeds |
|---|---|
| Candidates evaluated | 21,020 |
| Verdicts agreeing | 21,007 |
| Disagreements | 13 (0.062 percent of candidates; the 3 October census had 39 in 100,000 on its generator) |
| Seeds whose chosen program differs | 13 (every disagreement moves the chosen attempt, because the next attempt was accepted by both) |
| Exhausted seeds | 0 on either stand-in |
| Rejected by the closed form / by the memory-hard dataset | 1,013 / 1,014 (850 static, the rest (c)) |
| First failing (c) condition, closed form | const_bit 80, saturated 54, distinct 24, lane_const 4, bias 1 |
| Accepted margins, closed form | saturated at most 81 of 164, bias at most 120 of 136, distinct sum at least 247,335 (bound 245,760), nearly constant final bits up to 2,047 of 2,048 |
| Accepted margins, memory-hard | saturated at most 82, bias at most 115, distinct at least 247,678 |
The 13 disagreements: 12 are `const_bit`, a final register bit equal in all 2,048 evaluations on one dataset and in
2,044 to 2,047 of them on the other (7 where the closed form accepts, 5 where the memory-hard dataset accepts); 1 is
`bias`, output bias 155 against 93 (6.9 against 4.1 sigma, the two draws' difference 2.7 sigma of sampling noise),
where the memory-hard dataset accepts. No disagreement on saturation, lane-constant sites or the distinct count: those
metrics are the same to within 20 on both datasets. What an attacker gains from a program the closed form accepts
and the live dataset would reject: a register whose final bit is pinned in 2,047 of 2,048 hashes instead of 2,048,
which no test downstream of the fold can see (the 64 output bits stay within 120 of 1,024 on every accepted program)
and which no chip can turn into skipped work; the reverse direction loses the chain a program with one pinned bit.
Either way the chosen program moves to the next attempt, which both stand-ins accept. Nothing in the attacker's
favour: the verdict's dependence on the stand-in is a 0.06 percent coin flip on a one-bit property.
## Sub-row (b): the hot-set search
Run: `attack-f9 hotset` over seeds `igneum-f9/0` to `igneum-f9/999999`, 8 threads on cores 32-35,80-83 in
100,000-seed chunks; output `hotset.part*.tsv`. A 2,000-seed timing sample (`hotset-timing.tsv`, seeds 5,000,000 to
5,001,999) is summarised here; the 10^6 census replaces it when the run ends.
| Quantity | 2,000-seed sample |
|---|---|

FINDING F9-1 (or-saturation hot words). `inspect --seed 5000968` (`inspect-5000968.log`): the load at instruction 33
reads r4; r4 is written by `or r4 |= r0` (20), `mulhi` (27) and `or r4 |= r6` (28), and r6 itself by `or r6 |= r7`
(7). `or` is absorbing toward all ones: after two `or` writes from independent words every bit is set with
probability 7/8 and the whole register with probability (7/8)^32 = 1.4 percent; chained across iterations the mass
grows, and on this program r4 is 0xffffffff at that site in 731 to 739 of 2,048 evaluations in iterations 1 to 7
(36 percent). The site then reads one word, `rotl(0xffffffff x M, R) & window | offset` = 0x0ca59e4c for a full
window and 0x04a59e4c, 0x08a59e4c, ... for the windowed sites; near-all-ones values add a few hundred more. The
same word family appears in every flagged program (seeds 4,000,001, 4,000,037, 4,000,040 in the selftest: `or`
writes at 54 and 55 before the load at 60, or at 1 before the load at 3). Rule (c) does not see it: the saturation
test counts final register values only (the register is overwritten before the end), the lane-constant test needs
all 32 lanes equal, the distinct test counts per lane per hash (the hot word repeats across iterations, so it
costs one distinct of 128), and the output bias stays within tolerance. The 3 October census measured an
`or_sat_frac` per program (section 7.3, max 0.0102) but the adopted rule kept only the final-value count.
What it is worth to an attacker: nothing asymmetric. The hot words are the same for every lane that saturates, so
the GPU's coalescer and L1 already serve them without a DRAM transaction, and a chip gets exactly the same. What it
costs the design: those programs do fewer memory-hard reads than rule (c) promises (up to 10 percent fewer on the
worst program in 2,000, at least 1 percent fewer on about 1 program in 100), so the per-hash memory work of class
v4 is not the uniform 128 random reads the chip model assumes on every epoch. Gate reading: FAIL in the strict
reading (zero passing programs with a hot set under 1 percent of items), FAIL in the share reading too (programs
with a hot set capturing at least 1 percent of reads exist at about 1 percent of epochs). Proposed fix, for the hash
lane (not applied here): a per-site line in rule (c), "every load site reads at least 2,000 distinct addresses over
the 2,048 evaluations" (uniform gives 2,048 minus 0.008 expected repeats; the saturated sites read 434 to 1,855),
computed from the addresses the test already collects (one sort of 2,048 per site, 128 sites, under a millisecond);
the redraw rate rises by about the strict-reading fraction (8 percent of candidates) unless the threshold is placed
at the share reading. The alternative, dropping the `or` family from the draw table, changes the frozen weights and
is for the lane to weigh. Class check: a chip gains nothing today, but a stand-in that lets 1 percent of epochs run
with a 1 to 10 percent lighter memory side is a published-number problem (evidence row 17's per-hash reads).
(the 10^6 numbers and the hot-share distribution replace the sample when the census ends)
## Sub-row (c): header grinding
### What an attacker can steer
Only a load whose address register has not yet absorbed a dataset word is a function of the init words and the
nonce alone (taint analysis, `init_determined_sites`). On the devnet epoch-0 program these are the loads at
instructions 7, 8, 9, 10 and 31 of iteration 0; from iteration 1 every register is tainted. Over the 2,000-seed
sample the count is 1 to 7 per program, median 3, always in iteration 0 only. Everything after depends on dataset
words the miner must fetch first. The init words themselves are an FNV hash of the header and nonce_hi, so the
attacker cannot choose them, only draw them; and one draw serves a whole warp (the shuffles couple the 32 lanes),
so a per-lane draw costs 32 hashes per lane.
### The search (CPU)
`grind` draws K init words per warp (nonce_hi 0 to K-1 under the fixed prehash) and keeps the one with the fewest
distinct 128 B lines among the init-determined loads. Each try costs 32 lanes x (8 init + 32 prefix instructions) =
1,280 lane-instructions; the warp's hash costs 32 x (512 + 55,296) = 1,785,856 lane-instructions, the derivation
not counted. Logs: `grind-k10-crosssite.log` (lines counted across the five sites: coincidences that are at best an
L2 hit), `grind-k10-pages.log` (2 KB pages across the sites), and the `intra` runs (lines inside one load
instruction, what the coalescer merges into one transaction) that feed the card.
| Metric | K | Warps | Mean lines or pages saved per warp (of 4,096 loads) | Warps improved | Search per warp in hashes |
|---|---|---|---|---|---|
| lines across the sites | 2^10 | 524,288 | 0.895 (0.022 percent) | 89 percent | 0.73 |
| 2 KB pages across the sites | 2^10 | 65,536 | 1.455 (0.036 percent) | 98 percent | 0.73 |
| lines inside one instruction (intra) | 2^10 | 2^17 | (pending) | | 0.73 |
| lines inside one instruction (intra) | 2^14 | 2^17 | (pending) | | 11.7 |
### The card (RTX 5090)
Smoke run (1 round of 2 s per variant, `pod smoke` logs): the calibration of what one saved line is worth.
| Variant | What changes | MH/s | Against honest | W | MH/J against honest |
|---|---|---|---|---|---|
| honest | the pack kernel, one init per dispatch | 141.76 | | 482 | |
| perwarp-random | per-warp init table, no search | 141.73 | -0.02 percent | 486 | -0.7 percent |
| perwarp-k10 | per-warp table, best of 2^10 (cross-site table) | 141.74 | -0.01 percent | 487 | -1.0 percent |
| perwarp-k14 | (the same table in the smoke run) | 141.74 | -0.01 percent | 488 | -1.1 percent |
| pair | lane 1 reads lane 0's address at load 7: 1 line of 4,096 saved | 142.05 | +0.21 percent | 490 | -1.4 percent |
| forced1 | load 7 broadcast: 31 lines saved | 151.39 | +6.8 percent | 506 | +1.8 percent |
| forced4 | loads 7, 8, 9, 10, 31 broadcast: 155 lines saved | 203.11 | +43.3 percent | 530 | +30 percent |
| forcedall | every load broadcast: 3,968 lines saved | 399.61 | +182 percent | 520 | +161 percent |
Reading: the class v4 kernel on the 5090 is bound by its random reads (141.8 MH/s x 128 = 18.1 G reads per second,
the card's measured random-read ceiling in `docs/bench-log.md`), and a load instruction completes when its slowest
lane's transaction returns, so one saved line is worth about 0.2 percent of rate, 31 lines 6.8 percent, and the
five init-determined loads fully coalesced 43 percent. That ceiling is unreachable by search: it needs the 32
lanes' 28-bit addresses to fall in one line at five sites, probability 2^-115 per draw. What a draw can reach is one
coalesced pair at one site (probability 5 x C(32,2) / 2^23 = 3 x 10^-4 per try, about 3,400 tries per pair);
two pairs need about 6 million tries, m pairs about 3,400^m / m! tries. One pair is worth 0.2 percent of one warp's
hash and costs 3,400 x 1,280 lane-instructions = 2.4 hashes of search. The measured per-warp tables (5 rounds of
8 s, pending) are the direct check.
(the full run's table replaces the smoke run when it ends)
## Consequences per tier

### The card, the measurement (RTX 5090 pod ap-f9, `pod/host.log`, sha256 83b1372c..., copied to
`/srv/builds/igneum-wt-attack/attack-f9/pod/`)
Per-warp header grinding at K = 2^14 draws per warp against the honest kernel, 5 interleaved rounds of 8 s each:
141.62 against 141.61 MH/s, +0.004 percent of rate, sd 0.003, at 11.7 hashes of search per hash. The unreachable
ceiling (the five init-determined loads fully coalesced, `forced1` extended) is +43 percent. Gate: the grinding gain
under 1 percent of rate at any search cost. Sub-row (c): PASS. Pod time about 1 h 50 min from 09:02 UK; destroyed on
the lane's done line.
## Full censuses (box 1 parts 0 to 7 and 0 to 6; box 2 parts `edges-b2`, `hotset-b2` after the lane's move to
build-2 at 12:2x UK; `summarise.py` over all parts, 12:5x UK)
### (a) The edges on generator 4, 10^5 seeds
| Quantity | 100,000 seeds |
|---|---|
| Candidates evaluated | 105,064 |
| Verdicts agreeing | 105,030 |
| Disagreements | 34 (0.032 percent of candidates; the 3 October census had 39 in 100,000 on its generator) |
| By kind | `const_bit` 29 (closed form accepts 17, memory-hard accepts 12); `bias` 4 (3 and 1); `lane_const` 1 (memory-hard accepts) |
| Seeds whose chosen attempt differs | 34, every one moving to the next attempt, which both stand-ins accept; exhausted 0 on either |
| Rejected, closed form / memory-hard | 5,046 / 5,048 (static 4,201; then const_bit 424 / 428, saturated 275 / 275, distinct 112 / 112) |
| Accepted margins, closed form | saturated at most 148 of 164, bias at most 121 of 136, distinct sum at least 247,335 (bound 245,760) |
| Accepted margins, memory-hard | saturated at most 157, bias at most 126, distinct at least 247,571 |
The 20,000-seed reading holds at 10^5: the stand-ins disagree on a one-bit property (a final register bit pinned in
2,047 of 2,048 hashes against 2,048) and on four programs' output bias within sampling noise, never on saturation
or the distinct count, and never in the attacker's favour. Gate: the 39 edge disagreements reproduced and bounded.
Sub-row (a): PASS.
### (b) The hot-set search, 10^6 seeds
| Quantity | 1,000,000 seeds |
|---|---|
| Programs with any hot bucket (strict) | 75,400 (7.5 percent) |
| Programs flagged at the gate reading (hot share at least 1 percent of reads, or 7 constant address bits) | 11,696 (1.17 percent) |
| Worst hot share | 17.3 percent of the program's reads (seed 842871) |
| Hot-share bands (block init) | 0: 932,106; under 0.1 percent: 11,721; under 0.5: 3,645; under 1: 41,581; 1 percent and over: 10,947 |
| Sites with 7 or more constant address bits | 0 (max 6) |
| Fewest distinct addresses at a site in 2,048 evaluations | 43 |
| Most evaluations reading one address at a site | 1,838 of 2,048 |
| Mean hot share over programs | 0.063 percent |
Gate: zero passing programs with a hot set under 1 percent of items. FAIL on the class v4 stream by the letter:
11,696 passing programs concentrate 1 percent or more of their reads on a hot set. The mechanism is F9-1 above,
the or-saturated load source, which is the same fault class the F8 row found from the cross-hash histogram
(AP-F8-1: a load whose source's last writer is lossy); the two harnesses found it independently, one from the
program's address trace per site, one from the item histogram across hashes. F9-1 therefore merges into AP-F8-1,
and the fix is the amendment shipping in 0.3.20 (a load's source drawn only from registers whose last writer injects
or is a rotate). Sub-row (b): FINDING (AP-F8-1 class); re-gated on the amended stream with this harness below.

Consequences per tier (the rule of 5 October 2026): a 5060 Ti owner (16 GB, Windows) mines at 30.9 MH/s and 115 W from the box with nothing to set: about 5,100 blocks a day at the 522 MH/s the devnet showed at 14:44Z (one every 17 s, approximate: the network rate moves), about a quarter of a 5090 owner's 20,200, for 2.76 kWh a day (£0.79 at 28.5 p against the 5090's £2.11); through a Thunderbolt enclosure the x4 link costs nothing measurable (the hash is bound by the card's own memory latency, not the link; the 5090's PCIe-slot rows are the comparison), so a laptop with a Thunderbolt 4 port and this enclosure is a 31 MH/s miner. The 8 GB 5060 Ti: the same hash is the expectation (the 1 GiB dataset fits), a line owed. Proving on the 16 GB tier: the fleet's 4060 Ti 16 GB row (9.0 GB peak beside the miner on the patched server) says this card would mine and prove with about 7 GB spare, approximate until the host with the device selector ships; today the app's prover default leaves it off ("a full shard needs a 24 GB card") and the measured read is owed to the prover-floor host cut. Linux and HiveOS take the same CUDA worker (owed a line). What the lane does next: the prover-floor host's selector into the shipped WSL2 bundle, then the prove-beside read on this card; the Power Helper fault on PC 2 to the Ember lane (no efficient point on any PC 2 card until it answers).
Found on the way: inside a PowerShell `@( ... )` the comma binds before `+`, so `'--query-gpu=' + $f, '--format=csv'` is one argument (run a, void in 1 s; the query string is built first now); a bare string inside a function that also returns a value is swallowed into the caller's variable (the sampler line; `[Console]::Out.WriteLine` now); the app's `kind` for a Thunderbolt card reads `discrete` (a word for the Cards page to earn: `external`, which the state already names).

What is not there: no proof is produced, carried or checked on the chain (the devnet prover is a stub that signs claims), the proving pool pays nobody (row 21), the block proven is far below one shard, and the 60-second figure remains a design target; the pass mark is the standard in `docs/benchmarks/proving-e2e.md`.

A shard at the provisional `S_p` is 60.8 M SP1 cycles on the prototype pgas table (9 cycles per pgas, 44 per EVM gas; the modexp entry about 100x its SP1 cost); on an RTX 5090 (4 October 2026 evening, job run-20261004-173115) it executed in 1.63 s and its compressed proof took 10.9 s, verified in 0.040 s, so the 32 GB card is inside the 20 s target with margin. Whether a 12 GB card proves it at all, and in what time, is the next measurement (an RTX 3060 and an RTX 5060 Ti 16 GB are on order). A per-shard time can be met by shrinking the shard, so the project does not use it as a pass mark 5 October 2026, evening (bench-log "proving v1", the S_p curve): measured on the RTX 5090 with SP1 6.8.1's GPU prover, the card to itself, 1-s nvidia-smi samples: an empty shard 13,874 MiB and 2.2 s; a full shard at the ADOPTED v1 budget (30,000 pgas, 4.7 M cycles) 20,434 MiB and 4.3 s; the full prototype shard (6.75 M pgas, 60 M cycles) 28,307 MiB and 10.8 s; beside the miner 15,670 and 30,039 MiB. No environment knob of SP1 moves the 13.9 GB floor and the GPU server has no options of its own, so on this build a 12 GB card proves nothing, a 16 GB card only empty shards, a 24 GB card the adopted full shard alone and beside the miner (22,210 MiB and 13.2 s, measured on the 32 GB card: the 5090's allocation pattern, not yet a run on a 24 GB card) and a 32 GB card the prototype shard beside the miner with 2.5 GB spare.

Status: Conceded, stated (6 October 2026, evening; the Horizon lane analysis `docs/analysis/horizon/algorithm.md` sections 5.4 and 8, lane 2): the era draw and the instruction reserve are automatic schedule changes against fixed datapaths and against human forks; against the stored-dataset chip every drawn parameter is firmware, and the defence against that chip is the latency-shadow work (class v4) and the price-per-joule model. Stated in `site/litepaper.html`, Mining section ("These are automatic schedule changes ... every drawn parameter is firmware") and the "A chip is impossible" item ("a chip wired for one program is a bad bet ... not the schedule"), the "Every six months" row of the comparison table, and `site/index.html`, the hourly-program note ("a chip wired for one program is useless"). The phrase "automatic anti-ASIC escalators" is withdrawn from public text; it stays in the internal design summary until that is next edited.
Answer: Correct. The draw hides (M, R, pos, the op weights within +-2, the fold rotations) until 2 hours before each era, and none of those needs silicon. Biasing the draw is priced at 20 days of 100 percent of the network's hash for one more sample of the same space (lane section 5.4), so the draw is unbiasable at any price that matters and that is its whole job: it is a fairness device and a fork-free schedule, not a chip defence. What a chip wired for one program loses to is the hourly program itself; what the stored-dataset chip loses to is the latency shadow (class v4, 2.1x per joule at k = 1 and 3.9x at k about 0.33, the X9’s core, against the 5090 bench row; 0.9x and 1.7x against the Apple M5 Max; recalibrated under X35) and the price per joule, which is where the public claim now rests.

Lines: build-2 app gate 254 + 32 + 8 (seven new ladder tests); UI 67 (view 46, one new known-failed first); pre-push 56. No installer, node or host change. Captures ~/Desktop/igneum-previews-2026-10-07/first-block/01 and 02.
**Three more in (16:2x BST):** update-return-21b a64c193f (the eGPU card kind from a USB4 or Thunderbolt router in the device's parent chain, the Power Helper's fault line and its stale-prefix fix; app 255 + 32 + 8, UI 76); first-block-21 at cc9141cb replacing 6e555d47 (main's "seen once": the first-block card waits until a window has shown it, POST api/card/seen, ladder.rs card_seen; app 255 + 32 + 8, UI 67); miner-reliability-21 at 018440ae (the register: MF-11 in the update-return lane's words, MF-12 the pool stall, MF-13 the Power Helper's stale count; code unchanged since 4a28eb59, CI success). UI tests on the merged tree 76 of 76; the app gate on build-2 at the merged tip below. GitHub refused pushes with "Internal Server Error" from about 15:25 to 16:18 BST, transient.
**The node order, final (16:3x BST):** on 55768f88: c631c64b first (the test-only fix of the two stale integration targets, 1026 → 1282; both green on build-2 at 15:34Z), then 52e96c94, f067f7c1, b0444f51, 437f0438, 2e32d5f6, f95178a1, a6864e36, d8bceca5; the tip's suite set runs the consensus crate whole (`-p kaspa-consensus` without `--lib`: the lib and both integration targets) beside consensus-core, the miner, kaspa-pow, the exec suite and the three checks (the suite rule from the 0.3.20 known-red finding). era-vdf-node 394a5902 is 0.3.22's.

**The 0.3.22 app tree at 19:15 BST, release-0.3.22 c977786b on the box mirror:** 27ab317e (release-0.3.21 44b63ac9 + driver-check 46cc41e9) + pool-finish-21 8f2aae75 (the Devnet 3 split-read tool) + signing-22 e1b01654 (vote on by default pinned by test; Overview and Cards rows read signing or silent with the reason) + key-22 6501558f (scene/live-dag.js 2.0.5 legend, the app's chain card renders it, the site untouched) + c977786b (node_peers adds dn3-g1 64.119.209.250:21703 and dn3-g2 154.64.230.67:27017; self-test reads four). App gate on build-2 GREEN at every step (last 259 + 33 + 8, rc 0); pre-push 56 on each push. Riding if on the mirror by 19:45 BST, else 0.3.23: boot-start-22 (the engine starts at boot without a logon on Windows; a headless engine never reads a closed stdin as the host leaving), the export-wait reliability item (a worker never waits on the export past one retry interval), the driver-check hold-every-card-of-the-vendor rule, the UI lane's shard words. The Mac node pair builds on 34a2dbaa under the lock from 19:12 BST (r0322/mac-node-34a2dbaa.sh), then the DMG.
**PC 2 tonight:** the take-4 0.3.21 installer (mingw host, run-20261007-175020) was picked up at 18:51:57 BST before its removal deployed and the runner's abort ended the install in its first second (the build-server lane's fault, two rules added to the job tooling: an installs-app job is never removable without --force; never remove a published job without reading the machine's latest line); the update-return lane re-ran the kept installer at 19:07:56 BST and the 0.3.21 engine then restarted four times a minute apart and died ("quit requested by the window host went away (stdin closed)" 3 s after the node start: an engine started by a parent whose stdin closes at once); the founder reinstalled PC 2 by hand with the public 0.3.20 installer (45b2f3fb, the MSVC host; the public alias confirmed as that file by hash at 19:12:54 BST). PC 2 is read-only for every lane until its app uploads as 0.3.20; then the 0.3.22 installer job (--installs-app) and the smoke, one job at a time; then the Intel lane's driver retry with the minidump copy folded in (one UAC click). PC 1: released to the Counter lane's queue at 19:04:37 BST (the 0.3.21 MSVC host e223db18 built there in 9 s, collected by the relay Blob); one slot for the 0.3.22 host (app/windows/version.h moved to 0.3.22, host.cpp untouched).
## 8. Published: the Mac entry and the hive, both download folders (20:0x BST)
**The 0.3.22 tree closed at 5a84925b (19:46 BST)** = c977786b + MF-14 7a9c8371 (export wait) + driver-hold-22 f8ed911e (every card of the vendor) + boot-start-22 345336d8 (boot start, headless engine, no stdin quit) + shards-22 9a4d3429 + the pool daemon fix 9fd3b258 + window-22 07a97c65 (the opening size from the primary monitor) + boot-start-22 8da235e6 (the window host gate) + ota-cut a4f58820 (ui/VERSION 1.0.2, the pair check) + driver-hold-22 d571a120 (Intel 6733 row); app gate GREEN on build-2 at every step (last 269 + 34 + 8), UI 83, pre-push 59; then 58409175 (the Windows node pin to 34a2dbaa) and 4cdcab31 (the pool split-read tool) on the packaging and tools side only.
**Interface 1.0.2 LIVE 19:45:33 BST** in the 0.3.21 manifest (the Prove switch fix, cut from the 0.3.22 UI tree at 1d975bcc, min_engine 0.3.21, bundle 84b679ce), after the founder's Mac screenshot showed interface 1.0.1 (cut from 0.3.20) serving the pre-fix rules over the packaged 0.3.21 UI; the version-pair gate (pair-check.mjs) now refuses a manifest whose interface bundle is not from the app entry's tree.
**The token rotation (main's A, 19:5x BST):** the current dl token sits once in history (564acab5, a deleted bench log), so it rotates in 0.3.22: dl-token.next minted on the Mac (the first value voided at 19:54 BST after one tool trace printed it, its folder removed; the replacement's fingerprint 6a5f3d09, never printed), the new folder created, every cut from then reads the .next file (build-dmg.sh and make-payload.sh by default), the 0.3.22 manifests written in BOTH folders (publish-manifest.sh --dest and --base-url for the new one, the override, min_supported and the signed 1.0.2 interface entry carried by hand; the interface entry keeps its old-folder URL until 0.3.23 re-signs it in the new folder; the two manifests differ only in the folder inside the URLs), one deploy; the old value is refused 24 hours after the intake shows no header on the old path, the same clock as the floor file's removal; the history rewrite masks it. publish.mjs (ui-ota) reads dl-token directly and takes the .next rule on 0.3.23. The hive package carries no token. New jobs publish with URLs in the new folder.
**Mac LIVE 20:00:42 BST, channel devnet-3, both folders:** Igneum-Miner-0.3.22-34a2dbaa.dmg 5ec57528 (45,442,838 bytes; app 5a84925b, the Mac node pair 7346022d/d91ad025 built on the Mac under the lock from 34a2dbaa; packaged config igneum-devnet-3, four peers, no override file, the new folder's manifest URL), interface 1.0.2 with ui_version stamped, the floor file kept for the 0.3.20 and 0.3.21 apps; the old folder's manifest advertises 0.3.22, so every app moves on its next check; read back from both folders. Runbook r0322/deploy.sh (preflight: both manifests same fields, every mac URL inside its own folder). **HiveOS 20:03:07 BST:** igneum-hive-0.3.22.tar.gz 8ad6dcef (the 34a2dbaa hive pair glibc 2.31, the two hive-class workers, the two kit zips under packs/ incl. the Devnet 3 epoch-0 pack fce15bf61030be57, smoked in ubuntu:20.04) in both folders and at the public alias (publish-public.sh names the alias target from igneum-hive-<version>.tar.gz, so the public copy carries the plain name); the fleet sweeps the Devnet 3 nodes to 34a2dbaa after wave 1 (dn3-g1 first; the live shared-devnet nodes stay on c4459193 until the apps have moved).
**Devnet 3 first lock 20:02:46 BST:** checkpoint 235 LOCKED on both genesis boxes (block 50266abe, blue score 7050; dn3-g2 signed 100.1 percent of active, dn3-g1 98.4 percent), 1 h 56 min after the first accepted block; finality active from DAA 7,200; wave 1 of the standing boxes' second nodes started 20:03:06 BST. Proven share, first hour (19:59 BST read): 0.285 cumulative since genesis (no prover in the chain's first 51 minutes); ten provers claiming at about 1.2 times the chain's rate; the 24-hour window for mandatory verification counts from the first hour whose own segments read one. Relay cases on Devnet 3: CASES END rc 0 at 19:49:06 BST with the relay cell READ on the relay's own log (the poison's digest refused twice, 0 peers, 0 blocks); the hub-holds-target cell on a fresh pod goes in the record. The card (r0322/discord-card-devnet3-0322.md) read by main at 20:05 BST, three edits taken; it publishes the minute the Windows entry is live.
**Rule from the pool lane (recorded here and in the pool plan):** a pool daemon is built from the same repo tree as the chain's node, never a release behind; the 0.3.21-tree daemon hashed class v4 sub-version 2 against Devnet 3's sub-version 3 and refused every share as WRONG HASH; the Devnet 3 pair runs the 0.3.22-tree daemon (c15b39b0) since 20:02 BST. Also: a template every second on a 1-block-a-second chain outlived the 12-job window (25,477 unknown_job shares); the daemon keeps jobs 60 s or 256 per member (9fd3b258, in 0.3.22).
**Windows, in flight:** the 0.3.21 Windows entry is skipped in favour of 0.3.22's; window-22 changed host.cpp and the host gate refuses a host without the cut's version, so a fresh MSVC host builds on PC 1 in a slot after the hash lane's 5090 pass (about 20:20 BST, unelevated, no click), then host.sha256, the kit, the PC 2 installer job (--installs-app) and the smoke (0.3.21 to 0.3.22, the LG-4 timed steps as one measured row "one run, PC 2, not a fresh image"); reading about 21:30 BST. The rights-at-install step (3fbf4280) raises one UAC on a first install and the founder's rule tonight is no click, so it rides 0.3.22 only with a "deferred in a job session" commit by 20:20 BST, else 0.3.23. PC 1's elevated passes cannot run under the no-click rule; the hash lane rebuilt the efficiency pass through the Power Helper task (unelevated).

Launch gate LG-2 (seven daily hash-origin reports before the testnet) is waived by the owner, 7 October 2026 19:5x BST; the report
still runs daily from Devnet 3 (igneum-hash-origin-dn3.timer on build-1, 08:30 UTC, `--prefix dn3_`, DN3_GO_DATE 2026-10-07) and
from the testnet from its go. The testnet gate is now: the 24-hour proven window closed on Devnet 3 (about 19:00 BST on 8 October),
the 0.3.23 heights crossed on every Devnet 3 node, the launch text (LG-5) on the site, the seeds on the 0.3.22 object with the dry
run clean (done: fork 6ed56f63, digest 87d103b6, genesis 52a3e6a9, seed-class pair under /srv/artefacts/testnet-6ed56f63/seed/ on
build-1, three-seed dry run clean at height 0 at 18:44 BST), and the owner's word. The seeds stay armed for a go as early as the

- Ports: the bundled node listens on 26611 (p2p) and answers RPC on 127.0.0.1:26610 only.
## Shipped packs (0.3.22)
`make-hive-package.sh --kit <zip>` (repeatable) puts program-pack kits under `packs/` in the archive: the class v4 sub-version 3
kit (eight packs, program_id `a785001687d8688a` for the shared devnet's epoch 0) and Devnet 3's epoch-0 pack
`v4-devnet3-epoch0` (program_id `fce15bf61030be57`, exported under igneum-pow 017e7037 over genesis `4020cb43` as epoch and
era seed, day bytes for 7 October UTC). They are the rig's FIRST-START convenience: `h-run.sh` seeds `packs/devnet` from the
shipped pack only when the node's own export left nothing, so a rig mines from its first start; the pack is dated, and a rig
starting after epoch 0 (3,600 DAA) re-exports from its own node as before. The shipped pack is never the authority; the
pack-id gate reads `program.json`'s `program_id`.

// F10 (attack pass, 7 October 2026): the ladder's step rule under EXACT signal shares. The real-mining harness
// (latency-ladder.mjs, the ladder lane's) gives three equal CPU miners, so the only shares it can cast are 0, 33, 67
// and 100 percent, and a random miner's share in any one window scatters by several points, so no real-mining run can
// put 8,900 to 8,999 bps in the weakest of seven windows and hold it there. This driver removes the miner from the
// question the rule is asked: a 3-node network on the ladder fork with skip_proof_of_work, ONE producer that takes
// node 0's template, writes the ladder bits it wants into the header version (bit 15 up, bit 14 down, both or neither
// none) and submits it, one block per DAA score on a linear chain, so every window of W DAA holds exactly W blue
// blocks, one of each residue modulo W. A schedule names, per DAA range, the direction and how many residues carry no
// signal: with W = 100, 11 residues give 8,900 bps in every window whatever the window's alignment, 10 give 9,000.
// The three nodes read the chain and decide the rung on their own (processes::latency_ladder); the driver records
// every node's template (rung, weakest up, weakest down) at every poll, restarts a node mid-window on request, and at
// the end re-tallies the chain in JavaScript (an independent copy of the rule) and compares it to what the nodes did.

// ATTACK-PASS COPY (F10, 7 October 2026) of infra/fast-time/latency-ladder.mjs from branch ladder at 7003f9f5, taken
// verbatim except: (1) ROOT is found by walking up from this file to the tree that holds tools/finality-attacks/lib/rpc.mjs
// (the file lives at tools/attack/f10-ladder/ on the Mac and at attack-f10/ on the box), the two lib imports are dynamic;
// (2) the override file is this directory's copy of the ladder branch's override-60x.json (the attack-pass tree's copy
// lacks the latency_ladder fields); (3) ports, devnet suffix and data dir come from IGNEUM_F10_BASE / IGNEUM_F10_SUFFIX /
// IGNEUM_LADDER_TMP with the F10 defaults 29900 / 990 / /tmp/igneum-fast-time-attack-f10, so this network never collides
// with the ladder lane's (29720 / 972) or F7's (29800 / 980); (4) the binaries default to the box's ladder lane layout,
// read-only. The checks, the cases and the known-failed case are the original's, unchanged.
//
// The latency ladder's fast-time gate (docs/design/latency-ladder.md section 9; the class-v4-signal.mjs shape): a 3-node
// network on override-60x.json, class v4 from genesis (v3 and the v4 floor at 0, the class window 0: class signalling off,
// so the ladder opens the header's high byte on its own), the ladder active from DAA 0 with one window of --window DAA
// (default 60, one epoch; seven windows = 420 DAA, so the first epoch whose seed block has seven full windows below it is
// epoch 8 at DAA 480), each node's ladder signal set by IGNEUM_LADDER_SIGNAL (--signal a,b,c of up|down|none), one real CPU
// miner per node. Ports 29720 and up, network igneum-devnet-972, data /tmp/igneum-fast-time-ladder.
//
// The cases and the known-failed case:
// --signal up,up,none --expect no-step two of three miners signal up: about 67 percent, rung 0 must hold (run 10 epochs)
// --signal up,up,up --expect step all three: rung 1 (35 shadow passes) from epoch 8, the first with seven full
// windows, every miner's rung-1 program id equal to the CLI's --shadow-reps 35 id and
// unequal to the rung-0 id, and NO second step inside the next two epochs
// --signal up,up,none --expect step the known-failed case: the harness must report FAIL (no step happened)
//
// node infra/fast-time/latency-ladder.mjs --signal a,b,c --expect step|no-step [--window 60] [--secs 900] [--epochs 10]
// IGNEUMD, IGNEUM_MINER, IGNEUM_POW name the binaries (defaults: the ladder fork worktree's target/release and
