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.

the project lead watched the 9070 XT at 90% usage with its fans barely turning and the app could not say what it drew: the
draw, temperature and MH per watt line came from nvidia-smi only, and the earlier per-watt figure used the board
rating. proto-opencl/gpu-telemetry.c prints one line per AMD card per sample (bus from SetupAPI by the display
device's name, kind, name, watts, temp_c, fan_rpm, fan_pct, mclk_mhz, gclk_mhz, util_pct, source), built by
build-windows.sh against vendor/adlx (the SDK clone), shipped by make-payload.sh and push-inputs.sh. The engine
runs it with -l 5 beside nvidia-smi (Source::AmdTelemetry, tick_amd_telemetry), parse_amd_telemetry fills
power_w, temp_gpu, fan_pct, fan_rpm, mclk_mhz, util_pct and telemetry_at on the AMD card matched by kind and
ordinal, so eff_mhw and the dashboard's existing line show it; app.js shows fan and memory clock when present.
Tests: three on the parser with lines captured on PC 1 and the Mac fixture; the sysfs path ran on a fixture tree.
Measured over 20:27:45 to 20:29:41 UTC with both cards mining (docs/bench-log.md, under the 9070 XT ceiling table):
9070 XT 198.9 W (193 to 212), 64 C, 657 rpm, 2,505 MHz memory, 3,290 MHz shader, 100% busy, 17.73 MH/s =
0.089 MH/W; RTX 5090 307.6 W, 69 C, 44% fan, 122.30 MH/s = 0.398 MH/W.

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.

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.

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.

Under emulation (or --race with no other name) the race no longer times base alone: emu/test.sh passes again
(9 source checks, the serve protocol with prepare, swap and self-heal, 17 sampled hashes equal to igneum-pow).
Mac table: g256 (256 threads per threadgroup) +17.3% and +21.2% over the shipped 32-thread groups on two
programs, with the live app's worker sharing the GPU; the serve check found the unfair mutex (fixed in 123ee1a).

the project lead, 4 Oct 2026 evening: "we need to make our miner better than anything else can be". The compile-ahead pipeline
built one kernel per program; it now builds a catalogue (unroll 2 or 8; the dataset load path __ldg, __ldcg, __ldcs
on NVIDIA; a register budget by --maxrregcount or __launch_bounds__, max_total_threads_per_threadgroup on Apple;
2, 4, 8 warps per block or 64 to 256 threads per threadgroup; combinations), self-tests each against the pack's
vector warps (NVIDIA) or the base kernel over 2^16 nonces (Metal), bit for bit or out, and times each for about two
seconds with the job loop paused (one mutex, mining resumes between variants). Base is the pack's text as shipped,
always first, never discarded; a race has a budget (default 120 s against the 600-DAA lead) and keeps the best so
far when it runs out, so the swap is never delayed. One line per race: variants, MH/s each, winner, gain, time.
A tuning file (--tuning, IGNEUM_TUNING_FILE) pins a variant or orders the candidates per card model.
NVIDIA: textual rewrites on the pack's own kernel_bound.cu with exact anchors from igneum-pow's emitter, so the
pack format, the miner and igneum-pow are untouched and old packs race. --race --pack <dir> runs the race alone.
Under IGNEUM_EMU the race is off (the stand-in checks the handed-over text is the pack's). Metal: the MSL hooks in
generateMSL, a lock-protected kernel slot per program, a pair compiled inline races after its first job,
--race-test --seed --day runs the race alone with a table. OpenCL is not raced yet. docs/design/miner-tuning.md.

Root cause from the uploads (bench-log entry): the app exported the pack while its node was in IBD inside the previous
epoch, the OpenCL worker started after the boundary with no next epoch within lead, so no prepare was ever sent and
every job was a seed mismatch; the CUDA worker on the same PC had swapped correctly. Both workers now print
need <epoch> <day> before the error; the devnet-v4 miner (3bfe346f) prepares the current pair on a need line or three
mismatches, exits 42 for a worker without prepare support, and restarts a ready worker that completes no job for
60 s with jobs queued. Package rebuilt with the guarded miner (ship build on dc749905), payload inputs published.

Every Windows executable now ships with the coin icon Explorer shows and the version block Properties shows
(CompanyName Igneum, ProductName Igneum Miner, FileDescription per exe, 0.3.0, LegalCopyright Igneum contributors),
like the Mac app and DMG already do.
- igneumd.exe, igneum-miner.exe: packaging/windows/embed-resources.sh now takes the worktree and target dir
(defaults vendor/igneum-node-v4 and vendor/igneum-node/target-integration) and relinks with a linker shim first in
PATH instead of `cargo rustc -- -C link-arg`: cargo rustc takes one package and unifies features differently from
the two-package cross-build (300 crates differ), and a configured linker is fingerprinted and rebuilds everything;
the PATH shim changes neither. .rc files moved to 0.3.0.
- igneum-worker-cuda.exe, igneum-worker-opencl.exe: proto-cuda/nvrtc/build-windows.sh compiles the two new .rc
files with windres and links the objects; the icon is made with make-icons.py if missing.
- igneum-app.exe: app/igneum-app/build.rs runs windres on resources/igneum-app.rc for Windows targets and links it
(cargo:rustc-link-arg-bins, no crate dependency); it fails the build if the .rc version drifts from Cargo.toml.
- packaging/windows/resources/verify-exe.py: small PE parser that checks the .rsrc section, icon group and version
strings on the Mac; both build scripts call it, and it checks every exe inside the packages.
- proto-opencl/cl_dynamic.h: clGetEventInfo added to the run-time loader table (4714b51 added the call in host.c
without it, so the one-click OpenCL worker no longer linked under IGNEUM_CL_DYNAMIC).

After PC 2's gfx1036 (prebuilt-generic path) completed 2,000 jobs a second with no hash from 600 s on: every OpenCL
call in host.c's job path is now fatal on error (exit 3, the miner restarts the worker), the dispatch event must read
CL_COMPLETE, a chunk 20x faster per nonce than the running mean or an output buffer unchanged since the previous
dispatch is a fault, and a stats line every 200 jobs carries the live event and buffer counts (a leak over 16 events
or 12 buffers is fatal too). IGNEUM_FAULT_TEST=N exercises the detectors on a healthy device (verified on Apple
OpenCL: the stale-output guard fires on the chunk after the injected fault). The launcher shows 'worker fault' and
'restarting' for the card on the miner's WORKER FAULT line and drops the last rate. The emulation's NVRTC stand-in
now applies NVRTC's execution-space rule (program.h(46) igneum_launch_* declarations are host code unless
-default-device or -DIGNEUM_NO_CUDA), which is what the RTX 5090 reported; test.sh checks the rejection.

proto-cuda/nvrtc/worker.cpp serves igneum-miner's worker protocol with nothing installed but the NVIDIA driver:
nvcuda.dll and the redistributable nvrtc64_120_0.dll are opened with LoadLibrary (cuda_api.h), the pack's kernel.cu
and kernel_bound.cu are handed to NVRTC byte for byte up to the host launch wrappers with program.h and memhard.h as
named headers, every pack is self-tested against its vectors.h (cache head, last line, FNV-1a 64, dataset head, last
word, 64 samples, 96 vector lanes) before it serves a job, prepare runs on a thread for the hourly swap, and a job on
seeds without a pair makes the worker find the miner's pack by seeds.txt and build it. packfile.h (C99) reads a pack
directory. fetch-redist.sh verifies and stages the NVIDIA 12.8.93 redistributables and the Khronos headers
(THIRD-PARTY.md records URLs, hashes and the EULA clause); build-windows.sh cross-compiles with mingw (static,
KERNEL32 + Universal CRT only). emu/: the two libraries as host functions, the pack kernels on host threads, the NVRTC
source compared with the pack files; test.sh PASS on the Mac (two real packs, swap, self-heal, 17 sampled hashes equal
igneum-pow hash-bound). Not run here: the real NVRTC compile and driver load (RTX 5090 PC).
