Spec 06 rows O-3.1, O-3.14, O-5.9 and O-5.11 carry the sweep's evidence (fix row 124 done). M20: the devnet's pruning
point leaves genesis between DAA 108,000 and 151,200, about 14:00 UTC 5 October to 01:00 UTC 6 October, after which a
fresh node rejects the honest pruning proof under the stub. The ledger ends with the sweep's status-update section;
the review file carries draft counts and the three findings.

Live devnet v4: a second RTX 5090 joining 7 minutes into an epoch left the whole-epoch reference lane polluted for the hour; the short lane read 11 to 25% above it and the 25% trigger flipped between the two for 40 minutes (102M to 164M, 54 to 81 blocks a minute). Record and hash-rate truth under sim/difficulty/records/. sim.py gains a DAG model (miners on nodes with igneum-miner's template staleness, GHOSTDAG, the rule as the node runs it) and --live replay: std of log difficulty 0.115 against the record's 0.134, 4.3 peaks of 1.31x against 4 of 1.37x. The brief's candidates (short lane 240/360, ease clamp 3%, clamp once per DAA second, hysteresis, median of three) leave 0.09 to 0.13; capping the reference lane at the newest 600 blocks of the epoch gives 0.026 with no flips. Rule v2 = that cap, epoch lane only, behind difficulty_v2_activation_daa (devnet-v4 fork). Attack suite and synthetic set before and after, 3-node test network of the switch (testnet_v2.py), analysis document, spec 2.3, bench-log entry, ledger M24, fast-time file carries the new field.

A lock needs two thirds of all 30-day weight signing; finality pauses
whenever less than two thirds is connected and signing, the chain runs
on proof of work meanwhile and the node reports it. Spec 3.3, 3.3.1,
3.7, 3.9, 3.10 Q3 row, 3.11 rewritten with the new arithmetic (safety
one third in every view, liveness two thirds connected, the per-view
window bound stated as 3.7 item 9); O-3.15 decided, O-3.16 closed,
O-3.18 and O-3.19 narrowed. Simulator: --floor, the +local partition
mode, scenario L; A to L re-run at the 2/3 floor over five seeds with
the 0.85 deltas in results_v2.md. Litepaper finality sentences and the
'does not claim' item. Ledger F2, F9, F16, F18 restated, F21 added
(the window bound and the post-heal finality fork from the devnet).
Bench-log: node build and tests, simulator deltas, three-node six-voter
runs of 6A, 6B and 6A with a long heal on ports 29200 and up.

igneum-pow 0.2.0: generator v2 draws exactly 16 load slots from instructions 1..63, a
load's source from the registers written earlier and not read by a load since, the other
48 ops from the ten non-load weights; accept.rs is spec 01 section 1.4.6 (static: no
stale load source, every register injected; dynamic: 64 units on the seed-keyed
closed-form dataset, no constant bit, no lane-constant site, under 164 saturated, bias
within 136 of 1024, distinct addresses above 245,760); a rejected candidate is replaced
by the next attempt of the seed (seed || k_le32), 32 a consensus fault. Packs carry the
generator version, attempt and program id. Version 1 kept as generate_v1 for the census.
Packs: igneum-genesis, igneum-hourly, igneum-genesis-mh regenerated by igneum-pow export;
new igneum-devnet-v4-epoch0 (devnet genesis hash, day bytes 20730). Checks: Rust 39 of
39 tests; Metal natively via the Swift port (export cross-check 3 of 3 warps, identical
programs and vectors on five seeds incl. three with attempt 1, fuzz 2,000 of 2,000);
CUDA emu 4 of 4 packs; OpenCL emu 2 packs x 2 configurations; Apple OpenCL 4 of 4 packs
at 27.9 Mhash/s. Census 20,000: 5.225 percent rejected, accepted distinct mean 127.887.

Spec 2.3: rule 1 measures every chain step on a sanitised clock stored per header
(c(b) = max(c(p) + clamp(t(b) - c(p), -20 T, +20 T), t(b) - 60 T), step min(c(b) - c(p),
20 T)); rule 4 bounds the output to [2^128, MAX_DIFFICULTY_TARGET]; the timestamp rules
are Igneum's own, 10 s ahead of the clock and 10 s behind the selected parent beside the
unchanged past-median rule; new parameter rows, the bounds paragraph rewritten (the old
"next honest block cancels it" was the attack), the attack and test-network results added.
sim/difficulty/sim.py: class Igneum carries the same clock, lag bound and floor, so the
rule as simulated is the rule as coded (attacks.py's igneum-san is now identical to it).
docs/analysis/difficulty-2026-10-03.md section 11: the attack, the three parts, before and
after tables (simulator seeds 7 to 9, base-profile regression within 10% on the 3-seed
means, pool hopping unchanged, the two 15-minute 3-node forger runs), unit tests, limits.
docs/bench-log.md: the 4 October entry. docs/fud-ledger.md: M23, status Fixed.

Safety: X = 1/3 of total weight while honest votes reach every honest node within 41 min of median time; 4/30 = 13.3% across a longer partition, because only the 17/30 floor binds then (2 x 17/30 - 1). Liveness: Y = 17/30 connected and signing, T = P (1 - Y/(2(1 - Y))) + 107 s, 107 s at 2/3, 43 min at 17/30; below the floor finality pauses and the node reports it. Two certificates at one index: no verified lock is ever withdrawn, operators resolve (replaces the 3.5 re-evaluation). Seeds: uncertified checkpoint allowed (O-4.3 decided). Scenarios H (equivocator across a 50/50 split: conflicts at 12 to 16 min with 20%, none at 13%), I (40/40/20), J (signing stops 1, 6, 24 h), K (bought keys worth 20% and 40% against 30% hash), five seeds each. 3.10 rows for the gaps; open items O-3.15 to O-3.19.

The four public sentences (F18, P13, E11, L7 in site/litepaper.html and site/index.html) were swept into the concurrent commit cd604db; this commit carries the rest.
Spec 02: finality depth (43,200 DAA s, 12 h of median time) named as the reorg bound, merge depth as a merge limit only, simnet reorg test for gate 2; emission follows the code (365.25-day year, 63,115,200-s halving, 31.688 IGN per DAA second, reds inside the DAA window paid to the merger, E paid per block so coins are blocks times E).
Spec 03: W2 and Q1 denominated in past-median time, weight as a share of each 60-s bucket; W6 keys are free, weight is the only Sybil-resistant quantity; 3.8 and 3.9 point exchanges at the finality depth.
Spec 06: O-3.14, the finality simulation with the DAA in the loop under a pulsed rental (gate 3).
Spec 07: shard sortition draws by weight (blue blocks drawn uniformly from the window); proof-record validity is relative to the carrying block's own selected-parent chain; 1-key-versus-1,000-keys test.
Spec 08: release-key chain, rotation signed by the current key, revocation signed by the previous key, both published in a block; policy before the client ships.
Ledger: status lines for F18, P13, E11, L7, P11, F17, F14, M14, F15, E9, E10, G9; P8 cross-reference. Fixes: section 2.2 rows 75 to 88, with M15, M20 and P12 marked code, owner consensus engineer.

- 03-finality: Q2 participation from every vote seen in blocks (votes are
block payload); 3.3.2 the eclipse case closed by the 56.7% floor with the
sim v2 F2 numbers; 3.4.1 why aggregators cannot grind participation.
- 07-execution (new): EVM semantics on the DAG, shard sortition (8 provers,
10 s, then open, no shard bond), bridges (none official, no bridged
stablecoins at genesis, proof bridge with the consensus proof in phase two).
- 08-client-security (new): reproducible builds, release key in genesis and
in hardware, no silent updates, consensus only by 90% signalling, notarised
builds, official sources with the hash, seed confirmed before mining,
hardware wallet, the permanent seed line.
- 00, 02, 05, README, 06: cross-references, O-2.8 removed, O-3.3, O-3.7,
O-5.1, O-5.2, O-5.6 narrowed, O-8.1 added, counts kept at 60.
- Ledger: eight Status lines, status table, count table, overclaims 38, 40, 71.
- FUD fixes: rows 23, 26, 38, 62, 64, 66, 67, 70, 72, section 3 and 4.
- Site: bridge and stablecoin sentences no longer launch features; the seed
line wherever the app appears.

Decision of 3 October 2026: no fee to any team, foundation or fund.
Priority fee now splits 80% to the miners and provers of the block and
20% to the application called, attributed per call frame as before.
No burn of the tip; the base fee is still burned in full on both gas
dimensions. External proving jobs pay 90% to the provers who delivered
and burn 10%. The 60% signalling mechanism stays as a general tool for
parameters that genesis rules leave to miners; upgrades stay at 90%.
Ledger E4 closed by removal; E3, E5, G4, G5, G8, L1 and overclaims
45, 46 and 53 rewritten to the new rule.

docs/spec/01 to 06 and the README index, alongside the existing overview. Section 1 is the normative
definition of the lottery hash with test vectors copied from the igneum-genesis-mh pack (cache fingerprint
48c4f5bf24166b2e, 96 hashes, mixer constants) and every prototype value marked with the measurement that
fixes it at gate 1. Sections 2 to 5 are the design as decided on 3 October 2026, labelled Designed. Section 6
lists 60 open items with the experiment or decision that closes each and its gate.
