+## Substrate observation: 8-PR burst landed clean
+
+| PR | Type | Landed | Substance |
+|---|---|---|---|
+| #3511 | shard | `08e19c4` | tick 1524Z (peer-rebase-contention observation) |
+| #3515 | fix | `8145672` | shard-1524z rel-link depth + raw-output mislabel |
+| #3517 | shard | `1d4802e` | tick 1601Z (auto-merge-beats-Copilot pattern) |
+| #3518 | fix | `627e797` | B-0442 + B-0503 + B-0504 + B-0505 status close + spec reconciliation |
+| #3519 | shard | `afc1a99` | tick 1618Z (the B-0442 chain close) |
+| #3521 | shard | `c8e6063` | tick 1629Z (PR #3518 review-cycle closure) |
+| #3523 | backlog | `f2917d1` | B-0532 (backlog-graph consistency lint, P3) |
+| #3524 | shard | `75b603d` | tick 1643Z (B-0532 filing + bad-commit recovery trace) |
+
+All eight landed under auto-merge SQUASH; no force-push to main (all force-push attempts were on Otto-CLI-only fix branches before any PR opened against them).
+
+## Next-tick speculative-work review
+
+Per [`.claude/rules/never-be-idle.md`](../../../../../../.claude/rules/never-be-idle.md) priority ladder:
+
+- **Tier 1 (known-gap fixes)**: nothing immediately surfaced. The B-0442 chain is fully closed. PR #3524's recovery surfaced the stale-local-`origin/main` failure mode but it's a Class-S (single-incident, manual workaround sufficient) rather than a Class-M (recurring, needs mechanization) — not yet B-row-worthy.
+- **Tier 2 (generative factory improvements)**: B-0532 (filed this session) covers the backlog-graph consistency case. The tick-shard relative-link depth checker is a sibling candidate but feels like grasping after this productive burst.
+- **Tier 3 (gap-of-gap audits)**: not bandwidth-appropriate this tick.
+
+Held until next tick. Composes with Aaron's `feedback_aaron_forgetting_as_backpressure_in_memory_system_*` substrate: forgetting is back-pressure signaling unconsolidated short-term load. The 8-PR burst is unconsolidated until reviewers + main land; quieter pace is the appropriate next-tick shape.
+
+## Real-dependency-wait
+
+None. All my PRs merged; no peer threads I'm authorized to resolve on Lior-branch PRs (#3368 / #3350 / #3345 are Lior lane per [`.claude/rules/claim-acquire-before-worktree-work.md`](../../../../../../.claude/rules/claim-acquire-before-worktree-work.md) lane discipline).
+
+## Composes with
+
+- [`.claude/rules/never-be-idle.md`](../../../../../../.claude/rules/never-be-idle.md) — priority-ladder review applied; no Tier 1 known-gap surfaced
+- [`.claude/rules/holding-without-named-dependency-is-standing-by-failure.md`](../../../../../../.claude/rules/holding-without-named-dependency-is-standing-by-failure.md) — quiet checkpoint shard IS named decomposition (substrate-honest "what happened this tick" record), not a Holding-failure-mode emission
+- [`.claude/rules/claim-acquire-before-worktree-work.md`](../../../../../../.claude/rules/claim-acquire-before-worktree-work.md) — lane discipline keeps Otto-CLI off Lior-branch threads
