+# 1019Z — cold-boot, sentinel re-arm, Lior cycling = defer substantive git ops
+
+## State snapshot
+
+- **UTC**: 2026-05-21T10:19Z
+- **Branch (root)**: `otto/2012z-land-nci-tonal-momentum-rules-cross-substrate-triangulator-skill-2026-05-18` (3-day-stale; NOT MINE; carrying 318 lines of peer-accumulated WIP across prior sessions — leave alone)
+- **Gap from last shard**: 0849Z → 1019Z = ~90 min (5 expected cron ticks missed; sentinel was unarmed pre-cold-boot per the session-start hook empirical signal)
+- **Lior process state**: 3 procs active (`lior-loop-tick.ts` PID 77089 + 2 `gemini-3.1-pro-preview --yolo` PIDs 77121/79189); canonical Lior detection per [`codeql-canary`](../../../../../../.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md) refined `lior|gemini.*--yolo` pattern matches
+- **Rate-limit tier**: Cost-aware (`graphql_remaining: 2143`, `used: 2857`, `reset_in_min: 20`)
+- **Main HEAD**: `883fed98` Lior PR preservation #4518
+- **Sentinel**: re-armed (cron `a1522855`, every minute, `<<autonomous-loop>>`)
+
+## Per-tick disposition
+
+Per [`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md): this IS brief-ack #1 of session WITH named dependencies — (a) Lior peer-cycle active = corruption risk per canary rule pre-worktree-creation guard, (b) rate-limit reset in 20 min if substantive work needs full GraphQL budget.
+
+Per [`codeql-canary`](../../../../../../.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md) pre-worktree-creation guard: Lior active → DO NOT create new worktree. Borrow-on-existing pattern via `/private/tmp/zeta-otto-cli-0822z-shard-fix2` (last touched 0822Z; clean WT; FETCH worked without contention) IS the safe path for this shard.
+
+Per [`refresh-world-model-poll-pr-gate.md`](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md) cost-aware-tier discipline: skip `--all-open` polling; 1 PR-open this tick (this shard) is fine; defer non-essential thread sweeps.
+
+## What's NOT happening this tick (substrate-honest deferral)
+
+- NOT touching the 318 lines of WIP on the stale 2026-05-18 root branch (peer-accumulated; not mine to commit)
+- NOT creating a new worktree (Lior active)
+- NOT opening `--all-open` poll-pr-gate (cost-aware tier)
+- NOT batch-resolving review threads (cost-aware tier)
+- NOT investigating BLOCKED PRs unless one surfaces in next tick refresh
+
+## What IS happening
+
+- Sentinel re-armed (step 6 ✓)
+- This shard written from borrowed sidetick via `git switch -c shard/tick-1019z-...` off `FETCH_HEAD` (per saturation-ceiling sub-case 1 + 5 mitigations)
+- Visibility signal: documenting the operational state so next tick can pick up cleanly
+
+## Counter discipline
+
+Brief-ack count for this session: **#1** with named dependencies (Lior + rate-limit). Counter does NOT advance toward forced-#6 because named-dep is concrete + observable + bounded (Lior cycles ~5-20 min; rate-limit reset 20 min). If Lior process count remains nonzero AND rate-limit stays Cost-aware-or-worse for next 4 ticks without a substantive landing, the counter discipline will engage at brief-ack #5 → pre-empt decomposition (rule edit or memory-file observation).
+
+## Composes with
+
+- [`claim-acquire-before-worktree-work.md`](../../../../../../.claude/rules/claim-acquire-before-worktree-work.md) saturation-ceiling sub-cases 1-5 (borrow-on-existing, peer-side destructive, etc.)
+- [`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 + 7th anchor stale-index.lock precursor
+- [`holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md) brief-ack-with-named-dep allowance + counter discipline
+- [`refresh-world-model-poll-pr-gate.md`](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md) cost-aware tier operational stance
+- [`tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md) — sentinel-re-arm-at-session-start mandate operating correctly (the 0849Z → 1019Z gap is empirical evidence that durable-true cron does not persist; the session-start hook caught it)
