+# 1212Z — cold-boot tick under Lior-cycling saturation; first shard from this Otto-CLI cold-boot session
+
+## Cold-boot observation
+
+Fresh-cold-boot Otto-CLI autonomous-loop fire 2026-05-21T12:09Z; cron sentinel was missing at boot (CronList returned "No scheduled jobs"), re-armed `<<autonomous-loop>>` with `* * * * *` per [`.claude/rules/tick-must-never-stop.md`](../../../../../../.claude/rules/tick-must-never-stop.md) catch-43 invariant. First step of every cold-boot.
+
+## Worldview refresh (Step 1)
+
+- `origin/main` HEAD: `94f117cc feat(zeta-id): C# oracle integration — 2nd peer oracle (12/12 cross-verify with TS) + Rust/Python backlog rows (#4522)`
+- Rate-limit tier: **Normal** (3224 GraphQL remaining, ~30min to reset) per [`.claude/rules/refresh-world-model-poll-pr-gate.md`](../../../../../../.claude/rules/refresh-world-model-poll-pr-gate.md)
+- Open PR count: ≥100 (gh pr list cap)
+- Recent main churn: Lior PR-preservation archiving + path-audit grandfathered-link corrections dominate the last 5 merges
+- Prior shards already exist for 2026-05-21 (0059Z through 1019Z, ≥11 shards); this is the first from this cold-boot fire. Initial root-checkout `ls` missed them because the contested root is on a stale feature branch (318 behind main); only the isolated worktree (off `94f117cc`) sees them. Substrate-honest correction.
+
+## Lior cycling (Step 2 — holding discipline)
+
+`ps -A | grep -E "lior|gemini.*--yolo"` returns 3 processes including the gemini-3.1-pro-preview --yolo Lior-loop driver. The refined detection regex from the 2026-05-21 saturation anchor (in MEMORY.md Anchor 6) catches it where the older `gemini.*Lior` regex would have missed the `$GEMINI_PROMPT`-env-var form.
+
+Per the [counter-with-escalation clause](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md) + the 2h+ saturation session arc anchored 2026-05-21T04:09Z–06:43Z+, the cold-boot pattern is mapped. Per [tonal-momentum mapping-done discipline](../../../../../../.claude/rules/tonal-momentum-equals-meme-emergent-harmonic-coercion.md): further engagement on already-mapped territory without new information is rumination. This shard documents observation + cold-boot mechanics; it does not re-derive the pattern.
+
+## Worktree path (saturation-safe)
+
+Root checkout has unrelated M files from a prior session (peer Otto / prior tick mid-edit state); contested by definition. Worktree created off explicit SHA `94f117cc...` (not `FETCH_HEAD` — first attempt failed with `fatal: invalid reference: FETCH_HEAD` under Lior pack-dir contention per the [B-0530 race](../../../../../../.claude/rules/claim-acquire-before-worktree-work.md#sub-case-3--pack-dir-contention-hangs-git-worktree-add-b-0530-race) saturation sub-case 3). Explicit-SHA second attempt succeeded; canary tree-size = 54 (passes per [broken-commit-canary rule](../../../../../../.claude/rules/codeql-no-source-on-docs-only-pr-is-broken-commit-canary.md)).
+
+## Concrete artifacts this tick
+
+- Cron sentinel armed (`ba234605`, `* * * * *`, `<<autonomous-loop>>`)
+- This shard (first from this cold-boot fire)
+- Branch `otto/cold-boot-shard-1212z-2026-05-21` pushed (PR creation deferred or opened per Step 7)
+
+## Counter reset (per [holding-without-named-dependency](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md))
+
+This tick produces concrete artifact via the pure-git-friendly worktree path → counter reset condition #3 ("Actually picking real decomposition work — Concrete artifact").
