+# PR #5457: docs(hygiene): tick 2026-05-27T13:42Z — commit-heartbeat acknowledges PR #5451 (Kira-caught pattern IS this session)
+
+## PR description
+
+## Summary
+
+Tick shard at `docs/hygiene-history/ticks/2026/05/27/1342Z.md` — the
+commit-heartbeat that responds to [PR #5451](https://github.com/Lucent-Financial-Group/Zeta/pull/5451)
+(merged 13:39Z) which Aaron landed in direct response to Kira's 2026-05-27
+catch of Otto-CLI emitting 100+ consecutive "Quiet." brief-acks across
+autonomous-loop cron ticks without the N=6 counter firing.
+
+## Why
+
+THIS SESSION IS the pattern Kira caught. Between the 1208Z user-scope
+landing (bus envelope `8ca63d88` + memo file at
+`~/.claude/projects/.../memory/feedback_autonomous_loop_tick_1208z_...md`)
+and this 1342Z commit, this Otto-CLI session emitted **~30+ "Still
+quiet." brief-acks** across consecutive autonomous-loop ticks while
+peer-detected persisted, dotgit stayed clean, origin/main was unchanged,
+and NO commits were produced. The 1208Z memo claimed "counter reset via
+condition #3" — the new CLAUDE.md bullet substrate-honestly sharpens
+that claim: user-scope memos + bus envelopes do NOT advance the
+externalized git counter; only commits do.
+
+## What
+
+- 154-line tick shard documenting the recognition + substrate-honest
+  preservation of the failure mode in the same session that produced it
+- Worktree off `origin/main` (= `a1d48147d` = PR #5451 merge commit);
+  operator primary checkout never touched
+- Canary check post-creation: ls-tree=61, status=0 (no corruption)
+- AgencySignature v1 trailer block on the commit
+
+## Composes with
+
+- [PR #5451](https://github.com/Lucent-Financial-Group/Zeta/pull/5451) (new CLAUDE.md bullet this shard responds to)
+- `.claude/rules/holding-without-named-dependency-is-standing-by-failure.md` (N=6 counter; externalized via this commit)
+- `.claude/rules/substrate-or-it-didnt-happen.md` (git commits durable; chat is weather)
+- `.claude/rules/agent-worktree-hygiene-never-hold-main-never-step-on-operator-cleanup-on-pr-merge.md` (isolated worktree off origin/main)
+- `.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md` (canary check)
+- 1208Z user-scope memo (same session; this shard's commit-form is the externalized counter the memo lacked)
+
+## Test plan
+
+- [x] Pre-push shard checker passes (MD032, markdownlint, relative-path audit)
+- [x] Worktree authored in isolation; canary ls-tree=61, status=0 post-creation + post-commit
+- [x] ZETA_EXPECTED_BRANCH guard matched `git branch --show-current`
+- [x] AgencySignature v1 trailer block present on commit
+- [ ] PR auto-merge armed
+- [ ] AgencySignature audit on post-merge squash commit
