Conversation
- Fix adapters.list call shape: use object {topic, to} instead of
positional (topic, aligns with bus.list(opts) signaturesurface)
- Remove unused writeFileSync import from subscribe.test.ts
- Remove unused spawnSyncMock declaration and mock import from
work-assignment-subscriber.test.ts
- Update fakeList mock signature to match new object-arg call shape
Resolves CodeQL unused-variable findings and the tsc noUnusedLocals
failures that were blocking the BLOCKED threads on PR #3621.

Remove nonexistent subscriber command from tick checklist
The new refresh step invokes bun tools/bg/work-assignment-subscriber.ts, but this commit does not add that script (and tools/bg/ in this commit contains no work-assignment-subscriber.ts). Any agent following the mandatory per-tick checklist will hit a file-not-found error at step 1, which blocks the refresh-before-decide flow and prevents the tick from reaching later decision/work steps.

Pull request overview
Strict decomposition of PR #3621: lands the B-0449 subscribeOnce library + tests, marks the B-0449 design-pass row done, and removes the B-0460 work-assignment handler slice (intended to be put back on the backlog). The library reads matching envelopes from the bus directory, calls a per-envelope handler once, and persists a per-surface seen.json so subsequent ticks don't re-process.
Changes:
- Add
tools/bus/subscribe.tsexportingsubscribeOnce(topic, surface, handler)with surface-scopedseen-${surface}.jsonand Bun unit tests. - Wire a
work-assignment-subscribercall intodocs/AUTONOMOUS-LOOP-PER-TICK.mdstep 1 and updatetools/bg/README.mdpending list. - Mark
B-0449rowshippedand delete theB-0460row file; add adocs/claims/claim file.

- Deleting this B-0460 row file contradicts the PR description ("B-0460 put back on backlog") and leaves
docs/BACKLOG.mdline 268 pointing at a now-missing file (backlog/P1/B-0460-...-2026-05-14.md). If B-0460 is being restored to the backlog, the per-row file should remain (withstatus: open) andBACKLOG.mdregenerated so the index entry resolves. If instead the intent is to discard the row entirely, the corresponding entry indocs/BACKLOG.mdand the sibling references in B-0449/B-0459's body text need to be removed in the same PR.

* shard(tick): 2026-05-16T00:44Z — bg-worker triage, 4 BLOCKED PRs all peer-owned Otto-CLI background-worker fire (worktree `jiggly-riding-corbato`). Triaged 40 open PRs; 4 of 6 actionable are claimed by active peer workers (Lior decompose branches + sibling Claude worker on PR #3597). No PR matches the strict `BLOCKED + resolve-threads` criterion in this worker's task packet — threads are gated by failed CI / dirty merge state. Substrate-honest move: leave the branches to their owners + write visibility-shard so other Otto-CLI fires don't redundantly survey. Composes with: - `.claude/rules/holding-without-named-dependency-is-standing-by-failure.md` (named dependencies present; not Standing-by) - `.claude/rules/claim-acquire-before-worktree-work.md` (PR-thread- resolution is DOES-NOT-APPLY but worktree contention still applies) - B-0519 (multi-Otto-branch-state-contamination RCA) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(tick 0044Z): correct thread-carrying PR list + link rule path - Reconcile bullet with table: 4 thread-carrying PRs are 3597 / 3633 / 3621 / 3520 (not 3643 — that has 0 threads). 3621 is the parent of 3633 on `feat/b0449-b0460-subscribe`, not itself a Lior decompose branch. - Link `.claude/rules/claim-acquire-before-worktree-work.md` and the B-0519 RCA row to their full repo-relative paths per the rule-link convention from tick 2026-05-15T0503Z. Caught by Copilot review threads on PR #3649. Co-Authored-By: Claude <noreply@anthropic.com> * fix(tick 0044Z): correct relative link depth for .claude/rules and backlog/P3 paths Per Codex review threads on PR #3649: - Line 34: claim-acquire rule link needed 6 ../ to reach repo root from docs/hygiene-history/ticks/2026/05/16/ (was 5; resolved to docs/.claude/...) - Line 36: B-0519 backlog link needed 5 ../ (was 4; resolved to docs/hygiene-history/backlog/... which does not exist) Both links now resolve correctly from the nested tick path. * shard(0044Z): address Copilot review on PR #3649 Two findings from copilot-pull-request-reviewer: 1. Action-classification inconsistency: the shard said PRs #3633 and #3643 "both fail an identical set of 5 lint checks" while the table classified them with different nextActions (#3633→fix-failed-checks, #3643→wait-ci). Clarify the 5 lints are NON-required and explain the action divergence comes from independent required-check state, not from the shared lint signature. 2. Bare filename `refresh-world-model-poll-pr-gate.md` → full path link `[.claude/rules/refresh-world-model-poll-pr-gate.md](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md)` matching the link convention used elsewhere in this shard. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(markdownlint): prefix bare #3643 with "PR" to avoid MD018 Line 51 starts with `#3643` after wrap, which markdownlint reads as an atx heading without space (MD018/no-missing-space-atx). Prefixing with "PR " makes it a normal sentence continuation and matches the "PR #NNNN" style used elsewhere in the shard. Unblocks the required `lint (markdownlint)` check on PR #3677.

Empirical evidence: multiple recent PRs (#3670, #3659, #3643, #3633, #3599) show the lint check FAILING — meaning dead xrefs persist.
