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.

host.c --serve --pack <dir> serves a pack read at run time (packfile.h), whatever pack the exe was built against: the
first pair is built and self-tested like a prepared one (pairBuffers, pairSelfTest), prepared pairs are self-tested
too, the ready line says path prebuilt-generic. cl_dynamic.h (IGNEUM_CL_DYNAMIC) opens OpenCL.dll with LoadLibrary and
fills a function pointer per entry point, so the mingw build links no import library. test-generic.sh checks the mode
through Apple OpenCL with the packs of the CUDA emulation test: PASS (192 found, prepare and swap, 15 sampled hashes
equal igneum-pow hash-bound), built against a different placeholder pack than it served.

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 01 0.2 (1.4.2, 1.4.3, 1.4.6, 1.11, 1.15, 1.16, 1.17), igneum-pow README, the CUDA,
OpenCL and Metal test notes, bench-log entry, ledger M5 and M6 Fixed.

proto-metal --serve compiles igneum_hash_bound at runtime and mines jobs from stdin (init words in buffer 3, program
and dataset cached per seed); proto-cuda and proto-opencl host serve modes from the pack's kernel_bound.cu / .cl with a
seed guard; --vendor device filter for OpenCL. windows-miner/: START-MINING.bat + start-mining.ps1 (GPU and tool
detection, pack export, cached builds, MINERS identities per vendor, status every 30 s, uploads every 60 s, rebuild on
seed change, Ctrl+C summary), README.txt, make-package.sh (igneum-mine-test.zip with a cross-compiled miner).
docs: fork-divergence devnet v1, bench-log entry with the CPU, Metal and overnight numbers.

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.
