 ## Headline
 
 - **Post-summary reentry**: harness compacted prior conversation (~80+ autonomous-loop ticks, ~13h factory time); reentered at 1436Z. Cron sentinel `a2c54a1c` confirmed armed via `CronList` (catch-43 mandate).
-- **Loose-end flagged (not landed this tick)**: [`docs/backlog/P1/B-0442-missed-substrate-cascade-detector-background-service-2026-05-13.md`](../../../../backlog/P1/B-0442-missed-substrate-cascade-detector-background-service-2026-05-13.md) carries `status: open` despite ALL acceptance items checked off + slice-5 chain (B-0503/B-0504/B-0505) fully merged via PR [#3458](https://github.com/Lucent-Financial-Group/Zeta/pull/3458). Same for [`docs/backlog/P1/B-0503-b0442-slice5a-open-recovery-pr-core-function-2026-05-14.md`](../../../../backlog/P1/B-0503-b0442-slice5a-open-recovery-pr-core-function-2026-05-14.md) — `status: open` but `tools/bg/missed-substrate-recovery.ts` + test file confirmed present on `main`. The acceptance checkboxes on B-0503 also remain `[ ]` despite the work landing. **Not landed this tick** because peer-Otto is actively cycling primary worktree (see below) and the row-edit would interleave with peer's branch state.

 ## Substrate-honest disclaimer — why this shard is short
 
-Per [`.claude/rules/holding-without-named-dependency-is-standing-by-failure.md`](../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md): when a tick has no named dependency, pick decomposition / sanity-check / fix-thread. The substrate-honest pick for this tick was the B-0442/B-0503 row-status flip (sanity-check + clears the notifier false-positive). It was deferred for safety: primary worktree's branch state rotated three times during my refresh window, and committing a row-edit would race peer-Otto's in-flight DeepSeek-migrate-resume branch.

 This shard captures the observation so the loose-end is recoverable by future-Otto on cold-boot rather than evaporating with this session.
 
 ## Next
