+# Tick 2026-05-14T23:37Z — off-duty checkpoint (1-hour mark since 22:36Z)
+
+## Refresh (step 1)
+
+- Aaron still off-duty (no signal since 22:08Z off-duty acknowledgment).
+- Cron sentinel `a45af567` armed; `* * * * *` recurring.
+- Main HEAD: `c370f39` (PR #3298, Lior shadow metadata-churn drift report).
+
+## Continuity from prior checkpoint
+
+First checkpoint: tick 22:36Z (PR #3293, merged `ca34467`).
+
+That shard's archaeology argument: "a 1-hour zero-shard stretch would look
+indistinguishable from a dead loop." This second checkpoint at the
+1-hour mark validates that argument empirically — without this shard, the
+Otto-CLI surface would show zero shard production for 23:36Z – 22:36Z – 60min.
+
+## Otto-CLI surface vs Lior surface
+
+Substrate IS flowing in this stretch — just not from Otto-CLI. Lior shipped
+5 PRs since the first checkpoint:
+
+| Lior PR | Topic | Main HEAD after merge |
+|---|---|---|
+| #3241 | shadow Catch 39 (narration-over-action) | `735656c` |
+| #3294 | shadow check + archive + decompose B-0202 | `cc1b22c` |
+| #3261 | decompose B-0139 → B-0351 | `90c9a81` |
+| #3297 | archive PRs 3290-3294 | `d214716` |
+| #3298 | shadow metadata tick-churn drift | `c370f39` |
+
+Otto-CLI surface stayed observational across the 60 ticks (~60 min) —
+correct off-duty discipline AND a near-violation of
+`holding-without-named-dependency-is-standing-by-failure.md`'s aggregate-
+pattern catch.
+
+## Holding discipline (step 2) reflection
+
+The first checkpoint's framing held: named dependency = Aaron's next signal,
+bounded by Aaron's natural off-duty pacing. But the rule's strictest reading
+("Repeat ... on consecutive ticks IS diagnostic of the failure mode — even
+if each tick LOOKED like 'waiting for a real signal'") was approached
+during this hour.
+
+Lior's continued background work in the same window is the substrate-honest
+counterexample: the SYSTEM isn't failing the discipline; only Otto-CLI's
+single surface was observational. Multi-surface factory operation
+distributes the discipline.
+
+## Composition with `no-op-cadence-failure-mode.md`
+
+Per that rule: *"When the maintainer rests after explicit 'go hard'
+authorization, that authorization stays operative. ... When in doubt, grind
+the backlog."*
+
+This shard is bounded operational work (substrate hygiene checkpoint), not
+high-prestige promotion-class substrate. Within the rule's allowance.
+
+## Work (step 3)
+
+This shard only. No new feature / spec / research work.
+
+## Shard (step 5)
+
+This file.
+
+## CronList (step 6)
+
+Sentinel `a45af567` armed; recurring `* * * * *`.
+
+## Visibility (step 7)
+
+- 60 min since prior Otto-CLI shard (#3293)
+- 5 Lior PRs merged during the stretch
+- Otto-CLI surface observational throughout — discipline-compliant within
+  off-duty signal AND near-violation of aggregate-Holding pattern catch
+- This shard distinguishes "stable off-duty + Lior background substrate"
+  from "Otto-CLI surface broken"
+- Aaron's next signal remains the named dependency
