| Stage | Result | Evidence |
|---|---|---|
| unit | PASS | ceedling 61/61, 2.72 s |
| size | PASS | stm32f407disco device/cdc_msc vs master: TOTAL 14167 B, +0.0% every file (cmake-metrics/stm32f407disco/metrics_compare_device_cdc_msc.md) |
| pvs | pass=false — gate working as specified | GA:1=20 / GA:2=36; flags 5 GA:1 in files changed vs local master (midi2_device.c:245 V547 branch-new upstream; usbd.c V763 x3 + usbh.c:2109 V1008 pre-existing lines in touched files). Root cause of “changed” set: local master lags origin/master (upstream MIDI2 merge), so upstream churn counts as changed. Logic per spec. |
| build:stm32f407disco | BLOCKED (env) | agent type 'builder' not found — see registry note below |
| build:raspberry_pi_pico | BLOCKED (env) | same |
Resume: Workflow({scriptPath: '<worktree>/.claude/workflows/validate.js', resumeFromRunId: 'wf_4f10863f-6ff', args: {boards: [...]}}) — unit/size/pvs replay from cache.
dcd_rusb2.c:126 (matches the known hardware wedge) + CURPIPE spins (125, 249, 292, 477, ...) + CFIFO ISEL spin (347), each adversarially verified against code; one verifier corrected a scanner's claim that the Renesas manuals were missing from calibre (RA6M5/RX65N are present)..claude/agents/ — not the worktree's, and not on file changes mid-session. Runtime copies were mirrored to /home/hathach/code/tinyusb/.claude/agents/ (untracked); a NEW session is required for builder/port-dev/hil-operator to resolve.args arrives as a JSON string — all six scripts normalize with if (typeof args === 'string') args = JSON.parse(args).scriptPath when iterating.Resumed run wf_4f10863f-6ff once agents registered: build:stm32f407disco 43 examples, build:raspberry_pi_pico 43 examples, both PASS; verdict mechanics correct (pass=false only from the pvs stage's stale-local-master base; re-run vs origin/master in Task 17 is fully green).
2 port-dev workers (rp2040, stm32_fsdev): exactly 1-line diffs, git clang-format clean, both independently build-verified (verifyBuild: true), deps self-healed (get_deps stm32f0; PICO_SDK_PATH). Smoke edits reverted; tree clean.
detail = board locked: {holder JSON} verbatim, locked: ['raspberry_pi_pico'], retry attempted, no flash.locked: [].active the entire time; svc.sh never touched.BASE=origin/master (local master stale). No C changes → minimal path: software-only, boards=[stm32f407disco]. Verdict pass: true: unit 61/61, 43 examples, size +0.0%, pvs green (no C diffs). HIL correctly skipped.
pr-babysit {pr: 3761, maxCycles: 1, autoPush: false} (wf_361c9e0a-d0e) + direct pr-monitor triage of PR 3750 (3 Copilot rounds) from a /tmp checkout of the PR head. Results recorded when complete.
Stop-gate extra (done this session): board_lock cmd_hold holder-signaled success via pipe (c326eaacc), storm-tested 10/10 exactly-one-winner.
hold returned in 30 ms; pre-fix hung on the inherited pipe); is_locked() re-done as pid-liveness probe — never touches the flock, so status/pre-check storms can no longer fail a concurrent acquirer (0/15 failures under a 300-probe storm; hold storm still 1-winner-in-10).board-locked ❌ report row (report matches exit code); accumulate_report clears the stale marker once the board runs for real (3-scenario logic test green). failed-tests stays empty so re-runs repeat the whole board.autoPush now opt-in (default dry run; autoPush: true is the explicit push/comment authorization); RESOLVE_RECIPE paginates reviewThreads (pageInfo + cursor); post-push resolve step gained the same issue-comment 404 fallback as the refuted-replies step.--base-branch <base>; pvs stage now calls the new static-analyzer agent (sonnet, structured {pass, ga1, ga2, changedFindings[], detail}).static-analyzer (PVS-Studio SAST+MISRA, read-only) — mirrored to the launch-dir registry; registers next session (harness fact 1), so the validate pvs stage is unsmokable until then.. that made metrics_compare_base.py exit 2 on every run (regression from the 2026-07-10 batch).hil_test.py → refuse (CI mid-test, holder survives — verified); held otherwise → SIGTERM with PermissionError handled. Holder daemon truncates records on SIGTERM; success pipe dup’d above fd 2 (closed-stdio hold now succeeds — was orphan-holder + false failure, repro'd both ways).-b names exit 1 instead of a silent zero-test green (was exploitable as a false HIL pass through hil-validate); accumulate_report deletes an emptied board row (variant boards no longer leave a blank ghost row — 4-scenario test green).git clang-format -- <files> scoped to the worker‘s own files (bare invocation reformatted concurrent siblings’ edits in shared checkouts).-v -r 1 (diagnosis, not 3 more flake-retries).
