## 8. What is not done here
The IGCL telemetry reader (section 4), an Intel prover, the Linux package line, the driver-check feature (queued: per-vendor minimum-driver table in the manifest and one-click install, branch `driver-check` off the miner-ui-5 tip), and the site's bench table row, which takes the measured number only.
### 8 October 2026, 09:36 to 09:51 BST: a kit worker without the fix read the Arc as broken; the fix is now on master
The hash lane's class v5 fingerprint job on PC 2 (08:35:59Z) read its kit worker (igneum-worker-opencl.exe 27faa253, built from class-v5 1095eaa8) failing the self-test on the Arc before any batch, "vector lanes 96 bad of 96" on the v5 pack and on the class v4 control alike, every cache and dataset FNV matching. The question that decided the served row: the installed 0.3.21 worker's own self-test on the same Arc. Read from the intake, no job on PC 2: app run win-1ccfe586-20261007-201954, 20:23:56Z and 20:24:38Z, "self-test PASS (... 96 of 96 vector lanes)" with the devnet pack, then 54 blocks accepted with cpu re-check at 10.58 MH/s wall (STATUS at 21:06:33Z). So the kit worker regressed on Intel: class-v5 and master (3a4ba893) did not carry `proto-opencl/intel_rotr.h` (26e135a3 rode only the release-0.3.21 line and its children, release-0.3.23 and 0.3.24), so every OpenCL worker built from master or a branch of it evaluated every variable right-rotate as a left rotate on Intel. Landed on the mirror's master as a92bcce7 in 66192d65 (09:51 BST, the gate line and the manifest entry with it). The class: a fix that rides a release line and not master is lost by every branch cut from master; the Arc row on /miners stands (11.0 MH/s, 7 October).
