infra/build-server/capacity: igneum-capacity.service (user build, Nice 19, SCHED_IDLE,
CPUQuota leaving 8 threads free) runs run.sh, a controller over a priority queue of jobs
that pauses (SIGSTOP) the instant a build slot or the measure hold is taken (5 s poll of
/srv/builds/_locks) and resumes after. Jobs, each with a dry-run and a 10-min smoke:
pow fuzz (continuous, seed base advances), sync-request fuzz against a throwaway pruned
node on loopback (the Horizon 28-unwrap gate, igneum-p2p-probe sync-fuzz), GHOSTDAG and
finality sweeps seeds 1 to 1,000, model.py sweeps cached, clippy+audit per recent branch.
Summaries to /srv/workers/capacity.json; the worker dashboard gains a Background lane
(collect.mjs doc.background, page renderBackground). Night battery stops and restarts the
layer. docs/plans/build-server.md section 8. igneum-pow fuzz tests and ghostdag_sim.py /
attacks.py gain a seed-base knob for the continuous sweeps.

The fleet's 10-member load run (6 October 2026, 18:14Z to 18:24Z) accepted 0 shares: the pool fork's miner re-checked GPU
shares with a fixed class v2 program while the 0.3.14 workers hashed class v3 (docs/plans/pool.md section 9).
pool: node.rs builds the share verifier's seeds from the template's pow_epoch with the class and the era, installs the
node's genesis day, dataset size and class v3 activation beside the schedule, and sends program_class, next_program_class,
era_seed, era_index, genesis_day_index, genesis_dataset_log2 and program_class_v3_activation_daa in `seeds` and
program_class and era_seed in `job` (protocol.rs, additive fields); verify.rs tests through EpochSeeds::v2. Protocol,
vardiff, PPLNS, stats API and page otherwise unchanged. Suite 22 of 22 on igneum-build-1.
igneum-pow tests/recheck.rs: for class v3 (packs-ca2-mixer/mx8-devnet-epoch0) and class v4 (packs-ca3-v4/v4-devnet-epoch0)
the pack's program reproduces the pack's 96 vectors (the worker's reference), the chain seam the node engine calls
(Epoch::chain_program, chain_dataset_day) builds the same program, one known nonce hashes equal through both paths, and
the fixed-v2 program of the same seed disagrees; the pinned v3 and v4 program ids differ. 2 of 2 on igneum-build-1.
packaging/hive: the pool:// mode merged with master's per-card IDENTITIES=auto and OVERRIDE handling (selftest passes).
pool/README.md and pool.md: building on igneum-build-1 (the vendor/igneum-node symlink on the box).

A shadow block of S ALU instructions run R times at the end of every iteration, drawn from the program stream after
the 64 base instructions, behind LoadClass::shadow: v2 and v3 draw nothing and emit nothing (the pinned packs are
byte-identical, cargo test 54 + 4 + 19 + 7 green). The interpreter, the three kernel dialects (both kernels each),
program.h and program.json carry it; the acceptance rule interprets the base program only. Packs for seed
igneum-genesis over class mx8 at 4,096 to 180,224 shadow instructions per hash (proto-cuda/packs-ca3-shadow), and
the PC 2 bench playbook tools/ca3-shadow/pc2-shadow-bench.ps1 (passes the publisher's three checks).

A prototype behind a new LoadClass field (derive_len) and Shape field, Shape::for_class_day: every mixer slot of
the item derivation runs a straight-line program of 736 instructions drawn from the day key stream (the same
SplitMix64 stream, after the 40 mixer draws), twelve two-register forms, the chain rule of SuperscalarHash made
strict (every instruction reads the register the previous one wrote), an acceptance test with the x8 mixer's
operation and multiply counts from the code as floors (72 x 144 as written, 72 x 128 hoisted, 1,152 multiplies).
The verifier runs the program with a word-major (SoA) interpreter over the 32 items of a load, dispatching on
instruction pairs; no JIT. The emitter writes mh_round_0..8 into memhard.h, memhard.metal and kernel.cl. Packs
dr736-genesis and dr736-devnet-epoch0 under proto-cuda/packs-ca3-derive. The v2 and v3 paths are untouched: every
pinned pack re-exports byte for byte (tests/packs.rs), cargo test -p igneum-pow 58 + 7 + 4 + 19 + 7 green.

LoadClass::hot (Option<HotClass { mb, k, added }>) beside mix, slots, scratch, mixer_mult, growth and era; V3_CLASS = { era: None, hot: None, ..LoadClass::MX4 } (hot stays None: the hot code is behind the flag, measured and not adopted). Op::Hot, the hot slots drawn after the scratch slots, no width roll (v2_loads allows the added form's extra slots), the id suffix hot/<S><k>[added], the hot parsing inside parse_loads, the era branch first in name(). HotTable under seed_words("igneum-hot/" || epoch seed) with the cache chain and tag umHT, read at H[mulhi(src, HOT_WORDS)]; DatasetSource::hot attached by new_class_day and from_seed_bytes_class; the acceptance stand-in dataset_elem(idx, S[2], S[3]); the three emitters (hot argument after the init words, ht_segment and igneum_hot_fill beside the layout-aware cores); packfile.h hot fields beside class, era, attempt and mixerMult; OpenCL host, Metal packbench and NVRTC worker fill H on the device and self-test it. Eight packs under proto-cuda/packs-ca2-hot (replaced hot32k4 hot64k4 hot96k4 hot64k2 hot64k8, added hot32k4a hot64k4a hot96k4a) re-exported on the merged crate: vectors unchanged, program.h and program.json carry the mixer fields. docs/plans/hot-table.md (design, spec text, per-tier budget, chip model, Mac and PC measurements, the decision: layer 5 out of v3, the 3.0 note); bench-log entry and addenda with job ids and worker sha256s; the two PC playbooks.
Checks on this commit: cargo test --release 53 + 19 pass (the pinned v2, mx4, era, readwidth and hot packs); the pinned packs under proto-cuda/packs, packs-ca2-mixer, packs-ca2-era and packs-readwidth untouched; Metal packbench and Apple OpenCL --bench-pack on all eight hot packs (run lock, 2^20 at base 0): 96/96 lanes, hot table head, last line and FNV PASS, one fingerprint per pack on both harnesses, equal to the fingerprints before the rebase (hot32k4 679e5e83378d3790, hot64k4 d4c9e456b039fdef, hot96k4 7c98eceffee9fd73, hot64k2 f43b10a95879b8e5, hot64k8 c11309d743be9392, hot32k4a afb700b2d997c847, hot64k4a ba214baa9c1a9e85, hot96k4a 29e1916aed6deff5). No era or mixer behaviour changed: every resolution kept the ca2-v3 side and appended the hot branch.

main.swift: servePackProgram reads program.h with the packfile.h checks (generator 2 or 3, the class line against
the generator, the seed bytes, IGNEUM_SEEDW_INIT against attempt_words, class and era against the line) and
compiles program_bound.metal; the program store keys on (seed, class, era); a v3 job with no resident v3 pack
program answers need + error; v2 lines unchanged (Swift generation, the variant race); a pack program never races.
verify.rs: Epoch::chain_dataset_day(day, class, days_since_genesis, genesis_dataset_log2) and days_since_genesis,
the entry the node builds every day cache through (the ca2-mixer growth rule fills the body).

packfile.h: pf_load refuses a generator other than 2 or 3 (spec 01 section 1.4.5), reads IGNEUM_PROGRAM_CLASS
(must match the generator) and IGNEUM_ERA_SEED_HEX; pf_pack_class_ok and pf_class_token are the one rule for
the `class=<v2|v3> era=<hex>` tokens a job or prepare line of a class v3 epoch ends with (a v2 line is the
line of before, byte for byte). CUDA worker.cpp and OpenCL host.c: a pair's identity includes its class and era
when the line names them, so a prepared pack of the right class wins over the resident pack of the same seeds;
right seeds with the wrong class answer `need` plus `error <id> pack <dir>: program class mismatch ...`, and a
prepare on a pack of the wrong class fails in plain words. Metal main.swift: refuses every class v3 line until
the Swift generator carries version 3 (the integration branch). emu/packfile-test.c: the generator rule, a v3
pack with its era, the token matcher, the contradicting class line (13 checks pass).
igneum-pow verify.rs: Epoch::chain_dataset(day, class), the one entry the node's day cache goes through, so the
ca2-mixer class-specific item construction and cache schedule have a seam.

ProgramClass { V2, V3 }: V2 is the lottery hash exactly; V3 is generator version 3 on V3_CLASS, a PLACEHOLDER
set to w16 (LoadClass::fixed(4, 16)) that the integration agent replaces with the decided class. A v3 program's
id is program_id(3, seed, attempt) (spec 01 section 1.4.6). Epoch::from_chain_seeds(epoch, day, era, class,
label) and Epoch::chain_program build what the node's engine and the miner's export use; a v3 program records
the era seed bytes (Program::era_bytes). program.h and program.json of a v3 pack carry IGNEUM_PROGRAM_CLASS and
IGNEUM_ERA_SEED_HEX beside IGNEUM_GENERATOR 3; a v2 pack is unchanged (tests/packs.rs diffs the pinned packs).
packcheck: verify_pack_texts_chain / verify_pack_dir_chain refuse a pack of the wrong class, the wrong era, or
a generator other than 2 or 3 (PackFault::WrongClass); PackIdentity carries generator, class and era.
Tests: program_classes (generator.rs), program_class_and_era_are_checked (packcheck.rs); 42 + 11 pass.

Nothing changes for the default class: the pinned packs are byte-identical (tests/packs.rs), the v2 draw stream is untouched.
LoadClass {mix, load_slots, scratch}: fixed widths w16, w64, w64x4 (4 loads of 64 B), era mixes 50/35/15 and 25/50/25 drawn per load with one extra below(100) roll, and the scratch variant scr0/2/4/8 (persistent warps, 1 MiB per warp, tagged lazy fill, measurement only). A wide load reads the W-aligned address and folds every word: x = dst ^ w0; x = (rotl(x, 11) * 0x9e3779b1) ^ w[j]. Program ids carry the class. proto-opencl/host.c taken from opencl-rdna4 23810df (--memprobe, select read-back).

From 18:23Z both Windows workers (CUDA on PC 1 and PC 2, OpenCL on PC 1 after the 18:34Z node restart)
refused every pack for epoch 34 with "the epoch seed bytes do not give the pack's IGNEUM_SEEDW_INIT", and
the miner and the app restarted them every 5 to 60 s until 18:44Z and beyond. The packs were correct.
The generator retries a rejected candidate with seed || k_le32 (attempt_words); epoch 34's attempt 0 was
rejected (246 of 16384 final register values saturated, limit 163) and attempt 1 accepted, so the pack
carried attempt 1's words while pf_load (proto-cuda/nvrtc/packfile.h) derived the expected words from
the bare seed. Both workers also matched jobs to pairs by those bare-seed words, so even a loaded pack
of a retried program would have answered "epoch seed mismatch" on every job.
The rule, in one place per language:
- packfile.h: pf_program_words(bytes, attempt); pf_load reads IGNEUM_PROGRAM_ATTEMPT and checks the
attempt's words; the refusal says "program pack and its seeds disagree: IGNEUM_SEEDW_INIT is not
attempt N of the epoch seed ..." in plain words.
- worker.cpp and proto-opencl/host.c: a job belongs to a pair when the seed hex the node sent is the
pair's (pairIs); the compiled-in placeholder pack keeps the word comparison.
- igneum-pow/src/packcheck.rs: verify_pack_texts / verify_pack_dir, the same rule in Rust; the miner
checks every pack it writes with it before a worker sees it (vendor/igneum-node pack-loop branch).
Tests pin the attempt vectors of epoch 34 on both sides (one vector, two implementations), that
epoch 34 is attempt 1 and epoch 33 attempt 0, a known-good pack of a later attempt, a known-mismatched
(out of date) pack, and self-contradicting packs.
- proto-cuda/nvrtc/emu/packfile-test.c (+ .sh, in CI): pf_load on a known-good attempt-1 pack, the
checked-in attempt-0 pack, and the known-mismatched bare-words pack.
The app (app/igneum-app):
- watchdog.rs: PACK_OUT_OF_DATE_CODE 44, PackRebuilds (at most 3 pack exports per epoch, then the card
shows the reason), pack_refusal (the worker's "error 0 pack" line and the miner's "PACK OUT OF DATE"
line), pack_epoch_of; tests on the incident lines, known-good and known-mismatched.
- engine.rs: exit 44 exports the pack again before the restart instead of a blind restart, the strip
says "program pack out of date, rebuilding", the card and the log name the condition; at the cap the
card is marked failed with the reason and tries again in 10 minutes.
The relay (relay/lib/parse.mjs): PACK_MISMATCH; the card reads "pack mismatch, rebuilding (N refusals
in the tail, M restarts)" in `node tools/console.mjs machines` instead of a bare restart count; tests
on the PC 2 tail of 18:27Z and a healthy tail.

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.

Implements spec 01 section 1.6 (O-1.9): I = seed_words_from_bytes("igneum-block/" || H || nonce_hi_le32),
lane nonce = low 32 bits. Fixed here: H keeps the timestamp (nonce zeroed only), pow256 = lane in the top 64 bits
with zero low bits, interim day seed "igneum-day/" || day_le64, epoch seed = the 32 bytes of the epoch block hash.
Every existing function and the 288 pack vectors are unchanged; program_bound.metal and kernel_bound.cu are new
pack files.

Standard-library Rust port of the Swift prototype for the rusty-kaspa fork. 23 tests
tie it to proto-cuda/packs: program.json instruction by instruction for three packs,
cache FNV 48c4f5bf24166b2e, dataset head/last/64 samples, 96/96 hash vectors per pack,
and kernel.cu, program.metal, kernel.cl, program.h, memhard.h, memhard.metal byte-identical.
CPU verify 0.41 to 0.58 ms per warp (Swift 0.63 to 1.21), cache fill 175 to 181 ms one core.
CLI: bench, export, hash. program.json is written as valid JSON (the Swift quotes the
cache line mask inside the "item" string; fix pending in main.swift).
