+# Tick 2341Z — Otto-CLI background worker — PR #3964 thread resolution
+
+## Wake context
+
+Background-worker session woke into a worktree (`gentle-imagining-squirrel`) under autonomous-loop. SessionStart hook fired catch-43 reminder — `CronList` returned empty, immediately re-armed `<<autonomous-loop>>` sentinel at `* * * * *` (job 25e7ba72).
+
+Lior process active (`gemini` + `lior-loop-tick.ts` in `ps -A`) — high-contention window. Operated in pre-allocated factory worktree; verified clean (`tree_size=53, status_lines=0, matches origin/main`).
+
+## Work executed
+
+**`bun tools/github/poll-pr-gate-batch.ts --all-open`** — 105 open PRs; summary: 21 BLOCKED, 24 with `resolve-threads` next action.
+
+Filtered to `gate=BLOCKED AND nextAction=resolve-threads`:

+Lane discipline: Lior actively running; touching `lior/*` branches would split-brain.

+Three Copilot threads on `docs/backlog/P1/B-0582-destructive-verb-refusal-gate-substrate-level-2026-05-16.md`:
+
+| Thread | Line | Finding | Verification | Action |
+|---|---|---|---|---|
+| 1 | 11 | `composes_with: [B-0572, B-0581]` refs to rows not on main | `git ls-tree origin/main` confirmed B-0572 + B-0581 missing on main; `gh pr list` confirmed both in flight via #3952 + #3961 | No-op resolve; reply naming sibling PRs; per `blocked-green-ci-investigate-threads.md` "stale-but-fresh-looking" pattern — TRUE at thread-filing time, self-healing once siblings merge |
+| 2 | 67 | Grammar: "boxes IS" → "boxes ARE" | Direct line inspection confirmed | Fixed in commit `e0b95f406` |
+| 3 | 55 | Wrapper OR hook framing leaves close condition ambiguous | Open Question 1 already says "Probably: both" — Copilot is right | Restructured: removed `OR:` prefix, added leading note `Both coverage paths are required`, added explicit **Close condition** bullet naming slices 1 + 3 + 7 |
