+# PR #4716: docs(shard): tick 0802Z — Otto-CLI cold-boot, sentinel re-arm, PR #4668 named-dep unchanged
+
+## PR description
+
+## Summary
+
+- Otto-CLI fresh-session cold-boot at 2026-05-23T08:02Z; CronList empty (catch-43 condition); sentinel `37a0064f` armed
+- 8h sentinel-death gap since 0008Z (`5dd33255` died with its session per documented mechanism)
+- PR #4668 named-dep state unchanged from 0008Z (DIRTY, 12 threads, 55+ behind, auto-merge armed); continued decline-to-act on operator-authority territory per HC-8 + no-directives
+- Brief-ack #1 with explicit named-dep (counter not engaged per holding-without-named-dependency rule)
+- B-0615 partial-extract failure mode empirically reproduced (25s timeout killed worktree-add at 76%; 60s retry clean)
+
+## Test plan
+
+- [x] Tree canary: ls-tree HEAD~1 = 54, ls-tree HEAD = 54 (no commit-tree corruption)
+- [x] Branch-guard: `git branch --show-current` matched ZETA_EXPECTED_BRANCH before commit
+- [x] Substrate-honest abstention: shard references 0008Z rather than re-authoring its Class A + Class B disposition
+- [x] Compose-list cites the rules whose discipline this tick exercised

+
+## Pull request overview
+
+Adds a new hygiene-history tick shard documenting the 2026-05-23T08:02Z Otto-CLI cold-boot session, including sentinel re-arm details and an explicit “bounded-wait continuation” reference to the earlier 0008Z shard for PR #4668 disposition continuity.
+
+**Changes:**
+- Add tick shard `0802Z.md` with a compressed 7-step trace and sentinel-death-gap observation.
+- Record the unchanged named-dependency state for PR #4668 and the rationale for not re-authoring the 0008Z substrate.
+- Link this tick’s actions to the relevant `.claude/rules/*` discipline documents.

+### Thread 1: docs/hygiene-history/ticks/2026/05/23/0802Z.md:1 (resolved)
+
+**@copilot-pull-request-reviewer** (2026-05-23T08:11:52Z):
+
+P1: The shard header’s 3rd column is documented as the "<cron sentinel>" (see docs/hygiene-history/ticks/README.md and tick-shard-TEMPLATE.md), but this row uses `4537b0d23` (looks like an `origin/main` commit SHA) while the actual sentinel/job id (`37a0064f`) is only mentioned in the body. Please put the cron sentinel id in column 3 so future tooling/collation can rely on the header without parsing prose; if you still want to record the `origin/main` SHA, include it in the body summary or later in the doc.
