+# Tick 2026-05-16T04:44Z — Otto-CLI
+
+Fourth tick of this resume-session series. PR #3738 (0437Z shard)
+still in CI wait. Picked another P3 drift-catch candidate (B-0535
+backlog ID-uniqueness lint); verified shipped via PR #3565 + gate.yml
+wiring; closed via [PR #3742](https://github.com/Lucent-Financial-Group/Zeta/pull/3742).
+Third drift-catch of the session.

+| PR #3742 (B-0535 close, this tick) | OPEN, auto-merge armed |
+
+## Speculative work picked + rationale
+
+Per never-be-idle ladder + counter-with-escalation: PR #3738 is a
+real bounded named-dependency wait (~5min ETA), so a parallel-track
+substantive task is the right pick.
+
+Scanned six recent P3 status-open rows for drift:
+
+| Row | Status | Conclusion |
+|---|---|---|
+| B-0517 — MEMORY.md bloat cleanup + cadence | open | **PARTIAL** — Phase 2 tool (`audit-user-scope-memory-index.ts`) shipped via PR #3208; Phase 1 cleanup (100-130 entries) NOT done. Not pure drift. |
+| B-0532 — backlog-graph-consistency lint | open | PARTIAL — only "hard-error slice" shipped via PR #3567 (`--enforce-parent-child-status`); soft-warning + bidirectional consistency + docs not visibly complete. Need careful read before closing. |
+| B-0533 — §33 migration dead-xref sweep + lint | open | Slice B (scanner + enforce + gate.yml) shipped via PRs #3548 + #3555. Slice A (the actual sweep) may have been done by Lior in many separate PRs. Need a careful per-slice audit. |
+| **B-0535 — backlog ID-uniqueness lint** | open | **FULL DRIFT** — `audit-backlog-items.ts --enforce-duplicate-ids` shipped via PR #3565; gate.yml has `lint-backlog-id-uniqueness` job; all 4 acceptance criteria verifiably present. **Closed this tick.** |
+| B-0536 — orphan ferry-ref cleanup + audit FPs | open | Not investigated this tick |
+| B-0537 — MEMORY.md entry-length cleanup + CI gate | open | **PARTIAL** — Slice A cleanup (100 long entries) NOT done. Not pure drift. |
+
+Picked **B-0535** (cleanest specification, single-purpose, verifiable
+in 30 seconds via `grep gate.yml` + `ls tools/hygiene/`).

+## Substrate-honest takeaway on the drift-catch pattern
+
+Three drift catches in three ticks (B-0506 + B-0530 + B-0535) is the
+signal. The pattern is recurring enough to merit systematic audit,
+BUT the audit must distinguish:
+
+1. **Pure drift** — all acceptance criteria shipped; row's status flag the only thing missing (B-0506, B-0530, B-0535 fit here)
+2. **Partial completion** — tool ships but a content-judgment slice (cleanup, sweep, documentation) is still pending (B-0517, B-0537 fit here)
+3. **Multi-slice with sub-rows** — work proceeded via decomposition; original row could still be open as the umbrella (B-0532, B-0533 may fit here)
+
+A naive "all P3 status-open rows with shipped impl PR" sweep would
+incorrectly close partial-completion rows. The right audit needs to
+read each row's acceptance section and verify ALL criteria, not just
+"did any feat PR ship."
+
+**Filing this distinction as a future-tick consideration**, not yet
+as a backlog row — the pattern needs more empirical data points
+(say, 5+ drift catches) before justifying a formal audit-tool row.
