The harness now reads that seed on every run (`class-v5-harness/attempt-3-seed/{seed.json,state.igsd1}`, check `attempt_3_seed_reads_equal`: the engine path beside the run's CLI, attempt and id against the record's expectation; an unreadable side is a FAILED CHECK, never a skip); the node lane lifts the read into `igneum-miner program-id` on its next line |

Reads so far: the all pack on the CPU verifier (the NVRTC worker's emulation on build-1: check PASS, cache FNV 448274a57f508cbc, 96 of 96 vector lanes on the window's CUDA text); the partner on Metal and Apple OpenCL 5a6ad122a71a888f (both agree; the fold family fold f6c34aa6e87bf211 and rw 964ce3ba78b92a32 agree on both hosts and on the emulation too, the known-failed pairs distinct); the all pack REFUSES on both Mac hosts by construction ("kernel functions missing" on Metal, CL_INVALID_KERNEL_NAME on OpenCL: the window's OpenCL and Metal texts are refusal stubs in the merge, owed by the hash lane by 22:00 UK; the 0.3.27 pin's six-read rule waits on them, the coordinator's order of 17:05 UK).

Per tier: the window halves the hash rate at 7 percent less card power (a reg64 hash is twice the work: 128 statements and 32 loads per iteration), 5.80 µJ per hash against the partner's 3.13, level per unit of work; a miner on the window class earns the same per joule of hashing as on the partner. Remaining: the AMD RX 7600 on PC 1 (next in its queue; its own class v5 read on the kit's OpenCL worker 82b19cbde8557ea5 at 15.8 MH/s, quiet) and the Arc on PC 2 (about 18:30 UK), the all pack expected 59e6708e46f1e87c and the partner 5a6ad122a71a888f |

A fault of mine on the PC scripts (18:01 UK, the hash lane's read): pc1-v6-bench.ps1 and arc-v6-bench.ps1 at a9ea072d kept the class v5 script's one-pack leaves check (packs\v5-dn3-epoch0\leaves.bin), which stopped the 7600 job before its device list, and the AMD match was the 9070 XT's gfx1201 instead of the 7600's gfx1102; fixed at class-v6-kits c98a42c2e (18:10 UK, both mirrors, gate GREEN): a loop over each kit pack's own leaves.bin and the gfx1102 match; the hash lane runs its own fixed copy for the 7600 (run-ca3-pc1-v6all-7600-20261008-c), and the shipper has the ask to repoint PC 2's Arc job at c98a42c2e before its slot (default on a miss: the a9ea072d job fails in seconds on the leaves check and the fixed script queues next; past 19:00 UK the Arc read is the morning's and the 23:00 UK line reads five of six) |
