…ed 1336Z to peer Otto Fresh cold-boot fired by `<<autonomous-loop>>` cron. SessionStart hook reported no live `<<autonomous-loop>>` cron job — re-armed via CronCreate (job 311691b4, `* * * * *`). Detected peer Otto-CLI worktree at /private/tmp/zeta-otto-cli-0027z-sidetick on branch `shard/tick-1336z-otto-cli-2026-05-15` — my exact wake slot. Bus claim coordinator reported `unclaimed` for tick-1336z; branch existence was the implicit signal. Yielded 1336Z slot per claim-acquire-before-worktree-work + B-0519 multi-Otto contamination patterns. At 1338Z peer Otto rotated to feature branch (Ani extract); 1338Z slot freed. This shard lands from fresh side worktree branched off origin/main (90b7137) — no contention with peer Otto's working state. Substrate-honest gap: branch creation should auto-publish a bus claim envelope, or autonomous-loop ticks should `git branch -a | grep tick-<HHMM>z` before authoring. Decomposable future work.

Pull request overview
This PR adds a hygiene-history tick shard documenting the 1338Z cold-boot session, cron sentinel re-arm, peer-worktree collision handling, and the surfaced claim-coordination gap.
Changes:
- Adds a new per-tick history record for 2026-05-15 1338Z.
- Documents catch-43 cron defence and peer-yield rationale.
- Records future work around branch-created implicit claims vs bus claims.

Branch creation IS the implicit claim, but
tools/bus/claim.tsreportedunclaimedfor the slot. A racing peer that started earlier than me could have raced to commit before either side detected the other. Decomposable future work: have branch-creation auto-publish aclaimenvelope, or have the autonomous-loop tick checkgit branch -a | grep tick-<HHMM>zbefore authoring a shard.Test plan
