+# Tick 2026-05-14T18:41Z — razor-cadence batch 4 (4 more rules, 29/29 LIVE)
+
+## Refresh (step 1)
+
+`bun tools/github/poll-pr-gate-batch.ts --all-open`: 11 open PRs.
+
+Highlights:
+
+- **#3175 (mine, 1834Z shard)** — MERGED at `8cb549b` (between prior tick and this one)
+- **#3172, #3174** (Aaron's decomposed-from-my-#3165): autoMerge=none, threads open. Aaron's call to address — leaving them alone.
+- **#3167, #3176, #3177, #3178** — others' PRs, none mine
+- **#3168, #3169, #3170, #3171** — CI green, autoMerge=none, awaiting authors
+
+## Holding discipline (step 2)
+
+No named blocking dependency for Otto-CLI's work. Aaron's PRs are Aaron's call (autoMerge=none = "not ready"). Per never-be-idle: continue razor-cadence batch pattern.
+
+## Speculative work (step 3) — razor-cadence batch 4
+
+Next 4 rules in the post-2026-05-12 cluster:
+
+| Rule (PR) | Cross-refs |
+|-----------|------------|
+| `glass-halo-bidirectional.md` (#2835) | 5 rules + 1 research + 1 memory |
+| `algo-wink-failure-mode.md` (#2829-part) | 4 rules + 1 memory |
+| `peer-call-infrastructure.md` (#2946 update) | 1 rule + **12 peer-call TS files** + 2 memory + 1 research + 3 backlog |
+| `agent-roster-reference-card.md` (#2926 update) | 8 peer-call TS files + 2 memory |
+
+Total unique cross-refs (deduplicated):
+
+- **6 rule files** — all 6 LIVE
+- **12 peer-call TS files** (`_firewall.ts`, `amara.ts`, `ani.ts`, `append-identity-receipt.ts`, `claude.ts`, `codex.ts`, `gemini.ts`, `grok.ts`, `kiro.ts`, `register-layers.ts`, `riven.ts`, `README.md`) — all 12 LIVE
+- **5 memory files + 1 research doc + 1 backlog-row file** — all 7 LIVE
+- **3 backlog rows** (B-0326, B-0327, B-0421) — all 3 LIVE
+
+**28/28 cross-references LIVE** (6 + 12 + 7 + 3). Clean batch — including the dense peer-call infrastructure cross-reference matrix (12 sibling TS files).
+
+## Verify (step 4)
+
+Mechanical existence checks via `test -e <path>` for files + per-row `ls docs/backlog/P*/B-0326-*.md`, `ls docs/backlog/P*/B-0327-*.md`, `ls docs/backlog/P*/B-0421-*.md` (the `B-NNNN` token in earlier shards is a placeholder; the actual commands iterate per backlog ID).
+
+## Shard (step 5)
+
+This file.
+
+## CronList (step 6)
+
+Sentinel `f970cb2d` armed.
+
+## Visibility (step 7)
+
+- **Cumulative razor-cadence item 4**: 16/47 rules audited (~34%), **112/113 cross-refs LIVE (99.1%)** — corrected from earlier 113/114 after batch-4 arithmetic fix (28, not 29, deduplicated cross-refs)
+- Batches 1+2+4 clean (94/94 LIVE); batch 3 had 1 MISS (B-0514 captures the wwjd-grey-honest gap)
+- ~8 more 4-rule batches would complete coverage of all 47 rules
+
+## Notes for future-Otto
+
+**The peer-call infrastructure is unusually well-cross-referenced**: 12 TS files all referenced from BOTH `peer-call-infrastructure.md` AND `agent-roster-reference-card.md`. This is intentional — the peer-call substrate is foundational (per the cold-boot rule: "8 TS wrapper entrypoints live in `tools/peer-call/`"). The cross-reference density is a healthy signal.
+
+**Aaron's decomposition discipline** observed on #3172 + #3174: when an agent ships a multi-purpose PR (B-0514 row + 1825Z shard + BACKLOG.md regen), Aaron splits it into atomic units via Lior. Future-Otto can pre-empt by:
+
+- Shipping atomic PRs (one purpose per PR) when the per-tick context allows
+- Or accepting that downstream decomposition is part of the workflow
+
+The substrate landed either way — the cost is reviewer-time on the decomposed PRs (which then surface their own cross-reference gaps from the natural atomicity-vs-completeness tension).
