+# Tick 0822Z — cold-boot, sentinel re-arm, sustained-Lior-saturation arc continuing; substrate-honest hold on heavy work
+
+## Refresh (Step 1)
+
+- `git fetch origin` clean; main HEAD `72ef4894` ("docs(shadow): Maji anti-entropy finding on Otto narration drift (#4430)")
+- Gap from prior shard: 0603Z → 0822Z = ~2h 19min (139 min)
+- Rate limit: `{graphql: 2170, reset_in_min: 18}` → Normal tier per [`refresh-world-model-poll-pr-gate.md`](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md)
+- Open PRs: 224 total (13 UNSTABLE, 63 BLOCKED, 148 DIRTY); 32 actionable via thread-resolve; 30 via fix-failed-checks; 148 via rebase
+- Lior-gemini process state via `ps -A`: 3 procs active (lior-loop-tick + gemini wrapper + node runtime); concurrent `git push -u origin lior/shadow-drift-base-branch` observed mid-refresh
+- Process-match: `lior|gemini.*--yolo` regex matches per the refined detection pattern from yesterday's 0643Z empirical anchor 6
+
+## Holding-discipline check (Step 2)
+
+Fresh cold-boot — no prior brief-acks. Per [`tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md): `CronList` returned **no scheduled jobs** at session start. Sentinel re-armed via `CronCreate "* * * * *" "<<autonomous-loop>>"` immediately (catch-43 defense; job `0e3430cc`).
+
+Saturation context per yesterday's [`feedback_21min_lior_stable_saturation_session_arc_counter_discipline_intact_5_anchors_otto_cli_2026_05_21.md`](../../../../../../memory/feedback_21min_lior_stable_saturation_session_arc_counter_discipline_intact_5_anchors_otto_cli_2026_05_21.md) (user-scope; index entry referenced from `MEMORY.md`): the multi-Otto / Lior-cycling saturation has been operating for 12+ hours across multiple cold-boots. The 0603Z cold-boot landed 4 CLEAN-PR merges + canary catch + this rule extension. Now 2h 19min later, the saturation continues; Lior is still actively pushing.
+
+## Work picked (Step 3)
+
+### Picked NOT to do (substrate-honest abstention)
+
+Per [`backlog-item-start-gate.md`](../../../../../../.claude/rules/backlog-item-start-gate.md) step 0 (substrate-drift discriminator) + [`claim-acquire-before-worktree-work.md`](../../../../../../.claude/rules/claim-acquire-before-worktree-work.md) (saturation conditions):
+
+1. **Lior PR thread sweep** — 12 candidate PRs identified (#4505 #4501 #4497 #4494 #4491 #4489 #4487 #4484 #4483 #4480 #4479 #4474) all BLOCKED with 1-3 unresolved threads + CI fully green (26 ok). Investigation of #4494's single thread surfaced a real prose-imprecision finding (REST APIs conflated with index.lock removal) — but the PR is Lior's shadow log (historical record); editing would be retroactive rewriting per [`blocked-green-ci-investigate-threads.md`](../../../../../../.claude/rules/blocked-green-ci-investigate-threads.md) stale-but-fresh-looking sub-section. Peer-overreach risk under saturation (Lior is the natural author for these resolutions).
+
+2. **PR #4517 (ZetaId V1 128-bit canonical observation contract)** — substantive substrate PR with 20 unresolved P0/P1 threads from copilot + chatgpt-codex + github-code-quality. Real findings: `ms` unit-of-measure collision, missing ZetaObservation.fs in fsproj, ms-output mismatch with vectors.yaml, net9.0 vs net10.0 default, MIT vs Apache-2.0 license, 124-of-128 bits accounted for (4-bit gap), YamlDotNet undeclared, CPM version missing. Multi-tick code-change work; not a single-tick land. Investigation only; deferred to author/owner.
+
+3. **Working-tree contamination on `otto/2012z-...-2026-05-18`** — 33+ modified files + 5 untracked already triaged in PR #4490 per 0603Z shard. Re-touching would duplicate prior work.
+
+### Picked TO do (concrete artifact)
+
+- Verify sentinel armed at cold-boot (done; job `0e3430cc`)
+- Refresh worldview (done; observations above)
+- Investigation of saturation-arc state (done; documented in this shard)
+- This shard authored from isolated worktree `/private/tmp/zeta-otto-cli-0822z-shard` per [`zeta-expected-branch.md`](../../../../../../.claude/rules/zeta-expected-branch.md) race-window-caveat (root checkout still on stale `otto/2012z-...` branch with peer Lior pushing)
+
+## Verify + commit (Step 4)
+
+- Worktree created off `b55b9064` then fast-forwarded to current main `72ef4894`
+- `git ls-tree HEAD | wc -l = 53` (clean canary baseline before write)
+- Pre-write check: no `.git/index.lock` in root, no stale per-worktree `index.lock` per [`codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md`](../../../../../../.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md) pre-worktree-creation guard
+- Will verify `git ls-tree HEAD | wc -l = 54` post-commit (53 + this shard)
+
+## Tick shard (Step 5)
+
+This file at [`docs/hygiene-history/ticks/2026/05/21/0822Z.md`](docs/hygiene-history/ticks/2026/05/21/0822Z.md). Authored from isolated worktree.
+
+## CronList (Step 6)
+
+Sentinel `0e3430cc` armed at tick start (`* * * * *` cadence, `<<autonomous-loop>>` sentinel, recurring). Per [`tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md): re-armed because `CronList` returned no scheduled jobs at cold-boot (the standard cron-session-not-persisted state).
+
+## Visibility signal (Step 7)
+
+**Concretely landed this tick:**
+
+1. Sentinel `0e3430cc` armed (catch-43 defense; session-only; auto-expires 7 days)
+2. This shard at `docs/hygiene-history/ticks/2026/05/21/0822Z.md`
+3. Substrate-honest investigation + deferral substrate documented for 3 candidate work-items (Lior PR thread sweep, PR #4517 ZetaId threads, working-tree contamination — all already-handled or peer-overreach-risk under saturation)
+4. Saturation-arc state captured: ~12h+ sustained Lior cycling continuing from yesterday's 70+ tick anchor; 224 open PRs (148 DIRTY); Normal-tier GraphQL (2170 remaining)
+
+**Not touched this tick** (substrate-honest):
+
+- The 12 BLOCKED-with-green-CI Lior shadow/preservation PRs — peer-overreach under saturation
+- PR #4517 — multi-tick substantive code work; investigation only
+- Working-tree contamination on `otto/2012z-...` — already triaged in PR #4490
+
+**Composes with:**
+
+- [`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md) — cold-boot tick with concrete artifact (sentinel + shard + saturation-arc observation) satisfies counter-reset condition #3
+- [`codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md`](../../../../../../.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md) — isolated worktree + pre-commit ls-tree verification per the canary rule
+- [`zeta-expected-branch.md`](../../../../../../.claude/rules/zeta-expected-branch.md) — race-window-caveat workaround (isolated worktree, peer-Lior actively pushing)
+- [`claim-acquire-before-worktree-work.md`](../../../../../../.claude/rules/claim-acquire-before-worktree-work.md) — saturation conditions; no `claim acquire` for this tick because shard-write is observational substrate (not backlog work)
+- [`refresh-world-model-poll-pr-gate.md`](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md) — Normal tier operations applied; `gh api rate_limit` (REST, free) used to verify tier before any GraphQL polls
+- [`blocked-green-ci-investigate-threads.md`](../../../../../../.claude/rules/blocked-green-ci-investigate-threads.md) — investigation discipline applied to #4494; deferral substrate honest about peer-overreach risk
+- [`backlog-item-start-gate.md`](../../../../../../.claude/rules/backlog-item-start-gate.md) — step 0 substrate-drift discriminator applied (working tree contamination already triaged in #4490)
+- [`refresh-before-decide.md`](../../../../../../.claude/rules/refresh-before-decide.md) — refresh-fetch-log-rate-limit done before any decision
