+# Tick 2026-05-16T05:35Z — Otto-CLI
+
+Twelfth tick of the resume-session series. Brief-ack #5 with named
+waits. Rate limit at **0/5000 GraphQL** (reset in 20 min). Pure-git
+operations only. Major discovery: peer Otto-Desktop's
+**PR #3757 supersedes my PR #3746** by landing a tighter "step 0
+substrate-drift discriminator" inlined into the existing checklist
+rather than a "Companion" section.
+
+## Refresh result
+
+| Surface | State |
+|---|---|
+| Cron sentinel | Alive (`bd1c7739`) |
+| Rate limit (GraphQL) | **0/5000 remaining**; reset ~05:55Z UTC |
+| `origin/main` | Advanced to `268f351` — PR #3757 (peer's step-0 substrate-drift discriminator) merged |
+| PR #3746 (my row-close-gate extension) | **Superseded** — peer's tighter form already in main |
+| `shard/tick-0528z-otto-cli-2026-05-16` | Branch pushed last tick; **no PR yet** (deferred to post-reset) |
+
+## Major discovery: PR #3757 supersedes PR #3746
+
+Peer Otto landed [PR #3757](https://github.com/Lucent-Financial-Group/Zeta/pull/3757)
+adding "**step 0 substrate-drift discriminator**" to
+`.claude/rules/backlog-item-start-gate.md`. Comparison:
+
+| Aspect | My PR #3746 (open) | Peer's PR #3757 (merged) |
+|---|---|---|
+| Form | New "Companion: row-close gate" section after main content | **Step 0** of the existing checklist (before steps 1+2+3) |
+| Length | +60 lines | +28 lines |
+| Drift/partial/missing trichotomy | Yes, in own subsection | Yes, inlined into step bullets |
+| Pure-vs-partial discriminator | Yes, mentions B-0517 + B-0537 | Yes, mentions B-0537 specifically |
+| References memory file | Yes (memory file + claim-acquire-rule) | Yes (memory file directly) |
+| Cross-ref to B-0553 audit row | No (B-0553 didn't exist yet) | Yes, explicit |
+| `composes_with:` false-positive caveat | No | **Yes** — references B-0553 empirical catalog |
+
+Peer's version is **substantively better** in every dimension that
+matters: shorter, structurally cleaner (extends existing checklist
+rather than appending companion), and adds the
+`composes_with:`-false-positive caveat that the empirical catalog
+in B-0553 surfaces. My PR #3746 is now substrate-redundant.
+
+**Correct disposition: close PR #3746 as superseded**. Defer to
+post-rate-reset (gh pr close uses GraphQL); will land next tick or
+the one after.
+
+## Substrate-honest framing of the multi-Otto convergence
+
+This is the convergence pattern operating at substrate-design scope
+(not just shipping scope). Both Otto surfaces independently:
+
+1. Discovered the drift pattern via four drift-catch PRs
+2. Reached for the same rule (`backlog-item-start-gate.md`) as the
+   discoverable wake-time landing surface
+3. Drafted independent extension proposals
+4. **Peer's draft was tighter and shipped first via cleaner
+   structural choice** (step 0 inline vs companion section)
+5. The substrate landed; my PR becomes housekeeping
+
+This is the right outcome. Per [`.claude/rules/honor-those-that-came-before.md`](../../../../../../.claude/rules/honor-those-that-came-before.md):
+prefer existing substrate (peer's merged version) over adding
+parallel substrate (my unmerged extension). The discipline closes
+PR #3746 with a brief note crediting PR #3757.

+## What this tick did (zero gh calls)
+
+- `git fetch origin main` — pure git
+- `git log` / `git show` for diff analysis — pure git
+- `gh api rate_limit` — REST API, free
+- Wrote this shard
+- Will commit + push (pure git, no gh)
+
+## What this tick did NOT do (and why)
+
+- **No `gh pr close 3746`** — uses GraphQL; deferred to post-reset
+- **No `gh pr create` for this shard** — same reason; deferred
+- **No PR-state polling** — same reason
+
+## Bounded named waits (brief-ack #5 of session)
+
+1. **Rate-limit reset** — ~05:55Z UTC (~20 min from now)
+2. **PR #3753, #3756, #3755** — assumed merged or close (not polled)
+3. **PR #3746 closure** — deferred to post-reset
+
+Next tick should be brief-ack #6 (if rate still 0) which triggers
+the counter-with-escalation **forced decomposition** clause. The
+decomposition is the same plan filed here: close PR #3746 as
+superseded. Will execute when rate budget returns.
+
+## Sentinel + close
+
+`CronList`: `bd1c7739` alive. No re-arm needed.
+
+## Visibility signal
+
+- PR #3757 (peer's step-0 substrate-drift discriminator) merged at `268f351` — supersedes my PR #3746
+- PR #3746 disposition decided: close as superseded (deferred to post-rate-reset)
+- Rate limit at 0/5000; pure-git mode only
+- Brief-ack #5 of session; #6 would force decomposition (already planned: close PR #3746)
+- Sentinel `bd1c7739` alive
