docs(rules): add ID allocation discipline section to otto-channels reference card#3153
Conversation
…ference card Yesterday's B-0449 collision empirically validated a gap in the channels reference rule: agents pick monotonically-increasing IDs (B-NNNN backlog row numbers) by checking on-disk state but not in-flight PRs, race-condition manifests when peer Otto is filing concurrently. Adds new section "ID allocation discipline (multi-surface)" after Lane discipline, requiring BOTH: 1. On-disk check (find docs/backlog → grep B-[0-9]+ → tail) 2. In-flight check (gh pr list --search "B-NNNN") Empirical anchor: 2026-05-13 collision where Otto on Desktop picked B-0449 for PR #3052, but Otto on CLI had B-0449 in flight via PR #3046 (bg-services slice 5). Resolved by PR #3053 renumber to B-0450 + PR #3054 shadow lesson log. Also adds: - Item 7 to Operational discipline list pointing at new section - Composes-with entries for PR #3053, PR #3054, refresh-before-decide.md - /tmp/zeta-otto-id-alloc as example task-specific worktree path Re-authoring of work lost in yesterday's session crash (was on /tmp/zeta-otto-desktop which got cleaned up). The substrate gap is still real; the empirical anchor still holds; the rule update is still valuable. Co-Authored-By: Claude <noreply@anthropic.com>

The on-disk check in the ID allocation discipline section used 'find -printf' which is GNU-only and fails on BSD find (macOS default). Replaced with the portable pattern: 'find ... -type f | grep -oE "B-[0-9]+"' — the B-NNNN pattern only appears once per filename in practice, so extracting from full paths is equivalent. Verified portable: ran the new command, output matches expected (top 3 row IDs). Co-Authored-By: Claude <noreply@anthropic.com>

Pull request overview
Updates the Otto inter-surface communication reference card to codify ID allocation discipline across local backlog state and GitHub PR state, addressing the B-0449 collision scenario described in the PR.
Changes:
- Adds ID allocation as an operational discipline item.
- Adds a new multi-surface ID allocation section with on-disk and in-flight PR checks.
- Adds composition links to the collision-resolution PRs and refresh-before-decide rule.

…to find-portability fix) (#3154) Aaron-authored PR #3153 (ID-allocation discipline section) had a Codex P2 thread flagging `find ... -printf` as GNU-only (fails on BSD/macOS). Investigation found another agent had already pushed commit 1636908 with the portable-find fix (Aaron + Co-Authored-Claude); the thread was still open. Otto-CLI's contribution: verified the portable command works on this BSD-find macOS environment + closed the thread via GraphQL resolveReviewThread mutation. PR #3153 now wait-ci (6/7 required ok, 1 in-progress, threads:0, autoMerge armed). Also cleaned up stale /private/tmp/zeta-otto-id-alloc worktree (4h-old leftover from yesterday's session crash; PR body confirms original session was lost).

…rd (#3156) * chore(backlog): B-0506 — stale-worktree prune cadence mechanization (P3 friction-reducer) Otto-CLI 2026-05-14T18:13Z empirically observed 23 stale /private/tmp/zeta-* worktree entries left over from yesterday's session crash. The accumulation creates a recurring lockout pattern: 'git checkout <branch>' fails with "already used by worktree at <path>" even when <path> no longer exists on disk. Manual cleanup at 18:17Z: 'git worktree prune --expire=now -v' cleared all 23 entries. This row proposes mechanizing the prune via a small TypeScript audit tool that: 1. Enumerates worktrees + checks directory existence 2. Reports stale entries 3. With --prune flag, runs git worktree prune --expire=now Wire-up candidates: per-tick in autonomous-loop, or daily GitHub Actions cron. Filed as P3 backlog row (not implemented this tick) because the manual command works and the per-tick value of a new file + PR + CI cycle is less than the row capture. Composes with B-0400 (bus protocol), B-0444 (claim worktree field), claim-acquire-before-worktree-work rule, encoding-rules-without-mechanizing rule. Co-Authored-By: Claude <noreply@anthropic.com> * shard(tick): 1817Z — stale-worktree cleanup (23 pruned) + B-0506 mechanization row filed Pruned 23 stale /private/tmp/zeta-* worktree admin entries via 'git worktree prune --expire=now -v'. The accumulation creates a recurring "branch already used by worktree at <path>" lockout pattern that hit on prior tick (PR #3153 thread fix). Filed B-0506 (P3 friction-reducer) to mechanize the prune via a small TypeScript audit tool + per-tick or daily cadence wire-up. Side observation captured in shard: long-standing prior-session stash auto-popped during 'git stash push <untracked>' workflow, introducing conflict markers in tools/bus/claim.{ts,test.ts}. Reset both to origin/main; stash content discarded (alternative SHA-256 lock-path variant; if needed, derivable via decision archaeology). Composes with: claim-acquire-before-worktree-work rule, encoding-rules-without- mechanizing rule, B-0400, B-0444.

Side observation: multi-Otto ID-collision recurred despite PR #3153's ID- allocation discipline (on-disk + in-flight check). Both Ottos extracted top B-0515 from on-disk and incremented; in-flight check missed because the parallel Otto's branch had a non-standard name (chore/b-0516-gates-ecc-*) that didn't match the search heuristic.

…3307) New section "Worktree force-remove guard" between "When this rule applies" and "Composes with other rules" addressing an empirical failure mode that manifested 2026-05-14T18:13Z: Otto-CLI checked out Otto-Desktop's PR #3153 branch to investigate a Codex thread, hit "fatal: already used by worktree at /private/tmp/zeta-otto-id-alloc", and force-removed the worktree to take over. The PR-thread-resolution DOES-NOT-APPLY clause covered the WHY (legitimate cross-Otto work); it did not cover the HOW (force-remove vs new-path). Three operational alternatives now documented: 1. Create new worktree at distinct task-tagged path (cheap, default) 2. Use gh api / GraphQL for branch-state ops requiring no checkout 3. Bus-mediated worktree handoff for rare must-checkout cases Empirical anchor preserved in commit message + docs/hygiene-history/ticks/2026/05/14/1813Z.md Co-authored-by: Claude <noreply@anthropic.com>
Summary
Yesterday's B-0449 collision empirically validated a gap in the otto-channels reference rule: agents pick monotonically-increasing IDs (B-NNNN backlog row numbers) by checking on-disk state but NOT in-flight PRs — race-mode manifests when peer Otto is filing concurrently.
Adds new section "ID allocation discipline (multi-surface)" to .claude/rules/otto-channels-reference-card.md requiring BOTH:
The on-disk check shows merged state; the in-flight check shows what peer Otto is filing concurrently. Skip either and the race manifests.
Empirical anchor
2026-05-13 collision:
Substrate-honest takeaway
The `refresh-before-decide` invariant (`.claude/rules/refresh-before-decide.md`) applies at the per-ID-allocation scope, not just per-tick. The "highest on disk + 1" heuristic is incomplete; PRs in flight are also state.
Why now
This PR is the re-authoring of work that was lost in 2026-05-13 session crash (the original was on `/tmp/zeta-otto-desktop` which got cleaned up during the gap). The substrate gap is still real, the empirical anchor still holds, the rule update is still valuable.
