+# Tick 2026-05-16T06:47Z — Otto-CLI
+
+Twenty-second tick of the resume-session series. Rate at **433/5000**
+(extreme cost-aware; reset in 8 min). Pure-git tick — branch pushed,
+PR creation deferred to post-reset (~8 min) per the rate-limit-tier
+discipline.

+| Rate limit (GraphQL) | **433/5000** (extreme cost-aware; reset ~8 min) |
+| `origin/main` | Advanced to `7118b24` — PR #3785 (last tick shard) merged + peer's PR #3783 (B-0557 slice 1 `--check` flag) merged |
+| PR #3787 (last tick brief-ack) | Assumed wait-ci (not polled) |
+| This shard branch | Pushing without PR creation; defer to post-reset |
+
+## Peer Otto's B-0557 progress
+
+Peer landed [PR #3783](https://github.com/Lucent-Financial-Group/Zeta/pull/3783)
+— `feat(B-0557 slice 1): add --check flag to audit-backlog-status-drift`.
+
+That means the audit tool now has a `--check` mode (presumably for
+CI integration: exit non-zero if drift candidates exist). Composes
+cleanly with `gate.yml` wiring for ongoing drift detection.
+
+I'll explore the `--check` flag next tick when rate budget permits.
+
+## Why pure-git vs even-1-PR brief-ack
+
+Reset is 8 min away. Per the substrate-cost-at-the-reset-edge logic
+from tick 0554Z: firing `gh pr create` right before reset risks
+partial budget burn. Cleaner to wait one tick.
+
+Branch pushed (git only, no GraphQL); PR creation deferred. This
+shard documents the deferral; next-tick post-reset will create both
+deferred PRs (this one + any from prior tick if needed).
