# Row328 review packet — T9 timer race (#1826, Vikunja622)

Owner Fethry14f80e3c. Boyd first review, Dewey landing review; Sage owns slot/gate/landing.
Base2ce476d54; approved test source36668b698, concurrent support source06c57a7db.

Only package delta: packages/bus/tests/library-credential.test.mjs +4/-3 (Mos1594).
T9 helper defaults interval50; first start unchanged; second uses2147483647 TIMEOUT_MAX
with Mos comment. No assertion, other-test or product change. The startup tick still runs;
later periodic ticks cannot race the revoked manual verb. Never exceed TIMEOUT_MAX.

manifest.r1.sha256 freezes exactly that one file, SHA256 of manifest
1e0104683f49dcc96cb87975393665aa4ee30114055b4bbb45ad5e9ba9611733.
All other changes are tracking/scripts/receipts and append-only build/session records.

Sage4214 / Mos1599: eight concurrent loops x50, isolated TMPDIRs and fixture data roots.
M1 second interval50:374 pass/26 expected library-sync-busy assertion failures of400.
Restore exact fixed hash and full clean checks; fixed400/400 pass; whole file6/6 pass.
No other failure, skip/cancel or rerun. Outcome A; B construction alternative not required.
Initial absolute19 priority set in runner and every child; actual Node16/19 retained.
All counts, command, load averages and priority observations in BUILD.md and full evidence.
Own cwd process sweep empty; all child groups complete. Final diff/stat+porcelain empty
before receipts. Existing serial no-reproduction and aborted17 kept separate, not counted.

Full801 TAPs/run metadata/nice/provenance in evidence/sage4214-concurrent. Raw logs untouched
in scratch; normalized copies trim trailing whitespace, JSONL condenses metadata losslessly.
Sage's full bus suite and12 scripts landing gate remain pending; this is a review candidate.
