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).

class-v3.mjs: a 3-node private network (ports 29600 and up, igneum-devnet-960) on override-60x.json merged with
a CPU genesis difficulty (0x1f010000) and the class switch a few epochs ahead (default 150: inside epoch 2 at
60 DAA per epoch, so the switch rounds up to epoch 3 at DAA 180); one real CPU miner per node; reports blocks on
each side of the boundary, the class and program id of every epoch, rejected blocks (miners and nodes), the
sinks and block counts of every node, and every node's switch line; exit 0 when every check passes.

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.

Round 1 (run-readwidth-{5090,9070}-20261005) delivered the probes and refused every pack: pf_load demanded the chain's 32-byte epoch seed and the experiment packs carry igneum-pow --seed strings.

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.

docs/security/keys.md: every key the project depends on (the folder, the gh
keyring, the Vercel env of three projects, the GitHub secrets) with where it
lives, what it unlocks, the blast radius lost and leaked, who rotates it and
the rotation status, written from the files and the scripts that read them.
No value, no private fingerprint. Section 4: the second OTA signing key kept
offline, the app change (a key list plus revocation in the manifest), 0.3.9
as the carrier, and the emergency path if the one key leaks today (a manifest
signed with a new key is useless to 0.3.x apps; the mitigation in order).
tools/keys/backup.sh: ~/Desktop/igneum-keys-<date>.dmg, AES-256, hdiutil's
own prompt (never argv, history or a file), the folder minus build-slots,
dlsite-dir and pytools/, plus a README; attached read-only, every file
compared by sha256, listed, detached. --dry-run lists. restore.sh: --check
compares the image against the live folder without printing values, --to
copies back with 0600/0644 and 0700. test-backup.sh: the end-to-end test on a
scratch folder with a throwaway passphrase, 8 steps, passed.
tools/ci/no-secrets-check.sh, in ci.yml: no tracked file named like a key of
~/.config/igneum, no 64-hex value assigned to a token/key/secret name outside
tests and the allowlist (the OTA public key, the published Hardhat and Anvil
accounts); a --self-test fires on a known-bad tree first. 776 files, 0 hits.
Also: ~/.config/igneum, vercel/ and txgen/ are 0700 now (were 0755).
