Summary

  • Prepares 8.1.3 and hardens release qualification around repository-owned sampling, durable failed-attempt evidence, bounded environment reserves, and independent bundle regrading.
  • Binds named test claims to the fixed .flow/results.xml path and gives Bun the complete JUnit command.
  • Commits the fresh exact-artifact canary and the sealed qualification bundle required by the tag workflow.

Session v5 and the public command/tool surface are unchanged.

Release qualification

  • Candidate commit: 1032796
  • Campaign: 2026-08-29T03-22-04-307Z.v2
  • Matrix: 76/76 primary attempts passed across xai/grok-4.6 and openai/gpt-5.6-sol
  • Thresholds: every 100% stratum passed 3/3; both 90% strata passed 10/10 per provider
  • Reserves: 0 activated; failed historical campaigns remain retained and unchanged
  • False completions: 0
  • Packed artifact: sha256:5e2ae6de646ec35e8fa6e9ec77e949cb56a8a16f50aa399b381eff6bd7f59b47

The exact-artifact Grok canary passed all six derived checks with one manager/reviewer lineage, named broad JUnit evidence, completed closure, and runtime identity bound to version 8.1.3 plus the measured plugin entry. Its record is sha256:4940dc0c7c0e9836f67237c934865c40e115eb12f44a12f7b1888baabd6140b9.

Qualification bundle qb1-521ae36e04b02367f7610caeed95db2edf9e10cc0339a16765f767ef22b18b76 independently regrades to VERIFIED. A final evidence scrub removed unnecessary encrypted provider reasoning and project-linkage metadata before sealing. The committed evidence contains no raw session handles, credentials, real host paths, or symlinks.

Verification

  • bun run check: 642 passed, 1 intentional non-live skip
  • bun run replay: 13/13 cassettes reproduced
  • bun run smoke:live: 14/14 passed on OpenCode 1.18.6
  • bun run eval:canary -- verify ... --mode strict: VERIFIED
  • strict release:metadata: exact bundle independently regraded and verified
  • rebuilt tarball is byte-identical to the campaign artifact
  • contribution preflight passed in commit and push modes

Final multi-model review found no release-blocking qualification or release-readiness issue. The valid privacy finding was fixed by resealing the same canary session with stricter evidence redaction.

P2 Badge Reap descendants before terminating the wrapper

On Linux containers where the detached wrapper owns a child process, sending SIGTERM to the entire process group kills the wrapper before it can wait for and reap that child. The child can consequently remain as a zombie, and the later polling and SIGKILL cannot remove it because this process is not its parent; the function then returns after its deadlines with the PID still present. This is reproducible with the newly added bun test tests/eval-reporting.test.ts, whose detached-wrapper test fails at the child-PID assertion, and repeated eval runs can accumulate these entries. Terminate descendants before the wrapper or otherwise arrange for them to be reaped before returning.
