   Second full run on PR #99 (head f0ba462): 3895 pass, 3 fail, all in this file: 'exits nonzero promptly when the model is unknown', '--format json records an unknown stream finish and continuation', 'unknown stream finish preserves partial output and continues'. The same family appeared in the first #95 list, so it's the same flake. All 13 tests in the file pass in a Linux container. Also seen once in the fast job: prompt.test 'shell rejects when another shell is already running' hit its 30 s timeout, then passed on a re-run.

   Project tracking (project-manager pass, Project 16 "opencode Delivery", writer: claude-main session, 2026-10-05)

   Fields:

   • WT-PM-05 Priority P2: assessed by ornith-1.0-35b (Synapse auto, independent reviewer): "This is a flaky CI test failure requiring debugging, which represents standard operational maintenance without an immediate external business risk or blocked deliverable."
   • WT-PM-01 Owner: skipped, already Alter-Igor (written earlier in this session as the default). Assignees: defaulted to Alter-Igor.
   • WT-PM-02 Target Date: defaulted to 2026-10-05, a review-by date, not a delivery promise.
   • Docs: AGENTS.md § Fast-cycle delivery (the test: run-process subprocess tests time out only in the Linux full CI run #100 note).
   • Honesty note: this issue was already on the board before this session. Earlier in this session I set Status, Stage, Priority and Owner on it without first reading the old values, so any earlier values are not recoverable here.

   Checkpoint (WT-PM-09):

   • Where: branch run-process-ci-timeouts, worktree X:\opencode---run-process-ci-timeouts, PR fix(test): cap concurrent CLI subprocesses so run-process tests stop timing out on Linux CI (#100) #106.
   • Done: root cause found (CPU contention: about 10 cold CLI children at once on 4 vCPUs). The fix caps concurrent CLI children. Linux container: 54/54. The PR's first full run was green. 3 CodeRabbit findings were fixed in 408c61030a.
   • Next: (1) CI full + CodeRabbit on 408c61030a; (2) integrate; (3) merge.
   • Blocking: nothing.
