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(out of date) pack, and self-contradicting packs.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.

0.3.6 on both PCs: igneumd.exe (built on PC 1 with GCC 13's mingw) shipped with the Mac toolchain's GCC 16
libstdc++-6.dll, which no longer exports seven symbols the exe imports (std::codecvt_utf8_utf16 and a
stringbuf::seekpos); Windows refused the node with Entry Point Not Found. -C link-arg=-static had never removed
the libstdc++ import (0.3.5's Mac-built exe carries it too).
- packaging/windows/check-runtime-dlls.sh: objdump imports per DLL against the DLL's exports; shown to fail
the 0.3.6 pairing (7 missing) and pass 0.3.5's; run by push-inputs.sh before signing and by make-payload.sh
- push-inputs.sh: DLLs next to the exes first, then the Mac toolchain
- jobbuild.rs: the PC's windows stage copies its own toolchain's three DLLs into the pack (unit test);
build-job.mjs accepts the small DLL PE files and places them next to the exes
- cross-build.sh: -static-libstdc++ added as a try (measured on the 0.3.7 build)
- the six version files: 0.3.7
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.

windows.yml: parse job (every .ps1 through the Windows PowerShell 5.1 parser with a negative fixture, PSScriptAnalyzer
as warnings, parenthesis check of every .bat/.cmd with a negative fixture), build job (engine on the MSVC target,
window host through BUILD-APP.bat as it is, payload through make-payload.sh in Git Bash, installer through
build-installer.ps1, smoke run of both exes, launcher DRY_RUN, three artifacts for 90 days).
push-inputs.sh publishes payload-inputs.zip (node, miner, workers, NVRTC DLLs) to the downloads host from the Mac;
fetch-ci-artifacts.sh pulls the green run's installer and payload back into the downloads folder.
Host: --version and --help, version.h shared with host.rc. Launcher: DRY_RUN=1 prints the plan and starts nothing.

igneum-common.ps1 uses igneum-worker-cuda.exe (with nvrtc64_*_0.dll next to it) and igneum-worker-opencl.exe when they
are in the folder, passes the exported pack with --pack, and only surveys the toolchain (Find-Toolchain) when a worker
is missing or FORCE_BUILD=1; the dashboard and the status block name the path per card; a prebuilt worker that is not
ready after 150 s falls back to the build path once when a toolchain exists; 90 s of seed mismatch errors re-export
the pack and restart the vendor; WORKER_ARCH overrides the NVRTC target. make-package.sh ships the two exes, the two
NVRTC DLLs, the licence texts, THIRD-PARTY.md and TEST.md (what the first RTX 5090 run should print and what to send
back). README.txt, the bats, proto-cuda/README.md (nvrtc/ section), WINDOWS-MINER.md and the bench log updated with
what the Mac measured.

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).

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;

Windows combined package 0.2.0 (proto-cuda/windows-app): v4 exes from target-integration, peers = seed then Mac,
fresh appdir devnet-v4, one miner and one worker per card with --identities 8, --evm-address (PAYOUT_EVM or derived
per vendor from the PC name), voting on (VOTE=0 opts out), --prepare-packs for the hot swap with --exit-on-seed-change
as the fallback, --yes on the node, STATUS regex tolerant of the v4 now= segment, version in the dashboard header.
Mac app 0.2.0 (packaging/mac): v4 binaries, Metal worker rebuilt for macOS 11, data folder devnet-v4, EVM payout,
identities in one process, synced= flag honoured. Seed (infra/seed-nodes): stage-v4.sh builds v4 on the VM as a
niced, memory-capped transient service and installs a disabled igneumd-v4 unit with a fresh data dir; switch-v4.sh
swaps the units (--back reverses); health.sh reports active-v4. Runbook: docs/plans/cutover-2026-10-04.md.

proto-cuda/windows-app/: START-IGNEUM.bat starts igneumd, waits for sync, then runs the
miners; igneum-common.ps1 holds the dashboard, node, chain reader and miner functions once,
dot-sourced by start-igneum.ps1, start-mining.ps1 and start-node.ps1. STOP-IGNEUM.bat stops
everything in order. make-package.sh builds igneum-windows.zip.

proto-cuda/windows-node/: START-NODE.bat and start-node.ps1 (igneumd
--devnet with --addpeer to the Mac, status line every 30 s through
igneum-miner watch, keep-awake, random-delay restart, Ctrl+C),
BUILD-NODE.bat and build-node.ps1 (builds on the PC from the src.zip
snapshot; winget for Rustup, LLVM and protoc; MSVC default toolset),
ALLOW-FIREWALL.bat and allow-firewall.ps1, README.txt, cross-build.sh
(the mingw-w64 recipe that built igneumd.exe in 8 min 25 s; the exe
ships with the three mingw runtime DLLs) and make-package.sh.
WINDOWS-MINER.md gains "Run your own node"; bench-log records the
cross-compile and the two-peer sync test on the Mac (ports 27000 and
27010, live node untouched). The mining launcher's NODE_HOST=auto
edit stays uncommitted for the agent that owns start-mining.ps1.

The window now shows a dashboard redrawn in place every 2 s (Write-Host colours,
[Console]::SetCursorPosition): the Igneum mark, PC and node with connected/waiting,
one card per GPU with the hash rate in big digits, blocks found tonight and in the
last 10 minutes, one cell per identity (mining, starting, warming up, rebuilding,
waiting, errors, restarting, stopped), a network line from igneum-miner watch
(blocks/s, difficulty trend, share of the last 100 blocks), the last 5 events in
words and a footer. PLAIN=1 in the bat, a redirected output or a non-console host
give the old scrolling output. The launcher log keeps the full detail; miner logs
are read incrementally with FileShare ReadWrite.
The 0.00 MH/s / template age n/a lines were AMD identities whose first 16.7M-nonce
job took 100 s (the miner prints STATUS only after a job ends); the regex matched
the real format. AMD_JOB_NONCES=2097152 keeps those jobs near 10 s and the
dashboard says "warming up" until the first STATUS line. Crash restarts no longer
block the loop for 10 s. README and WINDOWS-MINER.md updated.

First Windows run (3 Oct 2026): nvcc linked without LIB (LNK1104 LIBCMT.lib) because cl was on PATH and the toolset

Exporter writes kernel.cl next to kernel.cu (same instruction list; memory-hard core emitted in a third, OpenCL C
dialect with the same literals as memhard.h). Pack headers are now C99-safe so a plain C host can include them.
proto-opencl/host.c: C99 + OpenCL 1.2 API, device list, runtime build, cache fill and FNV check, dataset build and
self-test, 3 vector warps standalone and in batch, bench and sweep as host.cu, whole-batch fingerprint. The 32-lane
exchange is sub_group_shuffle_xor only when the queried sub-group size for a 32-item work-group is exactly 32;
otherwise a local-memory exchange with one barrier per exchange, so wave64 hardware cannot change the hash
(WAVEFRONT.md). build.sh (macOS, Linux), build.bat (MSVC), README with the exact AMD-rig commands.
Proven without AMD silicon: Apple OpenCL 1.2 on the M5 Max 96/96 on all three packs (45.0 Mhash/s at 1 GiB, Apple
number, not AMD); pocl 7.2 CPU device 96/96 on both exchange paths including the real sub_group_shuffle_xor text;
CPU emulator 7 configurations incl. 64-wide sub-groups, identical fingerprint f99fb375b3abeaf5 everywhere.

proto-metal: default dataset is now the memory-hard construction (MEMHARD.md), --closed-form keeps the original.
Cache fill 2 ms GPU / 185 ms one CPU core; dataset build 20.6 ms; GPU cache == CPU cache on all 2^26 words.
Shortcut ratio: inline kernel 111x faster than honest (closed form) to 4.8x slower (memory-hard), 1 GiB.
CPU verify 0.63 to 0.80 ms per warp at 104 loads, 1.21 ms at 144 loads (4,608 items): 10 ms gate met.
Levers --load-weight and --wide-frac implemented and measured, both off; default generator unchanged.
Fuzz 200/200, edge, determinism, memcheck, stats re-run on the new dataset, all PASS.
proto-cuda: host.cu handles both dataset modes; new pack igneum-genesis-mh with memhard.h; clang emulation PASS
including the three-way cache check. Old packs unchanged; closed-form export is byte-identical to them.
docs/bench-log.md: dated summary.
Note: a concurrent session running git commit -a swept earlier states of these files into its site commits
