Refresh the status page: the acceptance is holding under hardening (per-op once bitmap, epoch/content-hash gate, 15 s CE grace; first-attempt 86% -> ~94-95%, fakes/run 3.39 -> 0.61), the hold-all-unreadable experiment is live, and the residual classes are named (late-decode corruption, early UVM channel-manager stall, guest init panic). Add an options section listing candidate techniques that would accelerate debugging toward end-to-end CUDA (deterministic fault injection, offline pump model, structured host tracing, guest-memory forensics, GR-wall metadata/golden reference/static-analysis throughput, cheaper supervised cycles, concurrency checks, tooling automation) - explicitly not directives, each requiring an eng-ops admission record.
docs: record GR promote-wall static findings (handler/commit map, external-VAS vaList gate, rec-677)

Refresh the public status page for the 2026-10-04 acceptance: noclaim38/39/40 report MAIL + VADD n=1048576 bad=0 checksum=392344090.500000 + STATUS OK with identical hashes (committed aa3520f2); the repeat campaign shows 14 of 15 green with the remaining failure the known intermittent guest-side flake. Update the milestone ladder (CUDA kernel execution now green via the no-claim host bridge; guest engine forwarding to the physical GPU still the open backend wall) and the milestone index/log.
STATE-CURRENT: 15:12 check-back snapshot (no-claim bridge reaches guest vectorAdd launch; mail read-back fixed; bridge slot oops + approved reboot; post-reboot run blocked by guest boot panic)

- kernel: gsp_cuda_bridge (QMD launch capture, debugfs job/out/done, param+output resolution cached from inline writes), sema drain fixes (never hold/starve a channel), GR ring autopin + counter autoreg, per-page push reads, counter-derive gate; module builds clean
- tools/cuda-bridge: CUDA driver-API daemon executing mail/vadd kernels on the physical GPU, CUBB2/CBD2 v2 protocol, layout check + self-tests
- tools/guest-diag + tools/cuda-ab: scanner/pin fixes, victory push-only mode
- debug/risc-v-gsp-rm-vm: Phase S simulator wave (GSP device model, boot ladder, triage/re-demo harnesses, docs 30-41), GPGPU-sim scaffolding
