+- Rate limit: 4911/5000 remaining (healthy).
+- 9 open PRs. Mine: only #3189 (1903Z batch 6 shard) wait-ci autoMerge armed. Prior #3187 merged into main at `6756514`.

+## Holding discipline (step 2)
+
+Named: #3189 wait-ci. Parallel work = razor-cadence batch 7.
+
+## Speculative work (step 3) — batch 7
+
+Four more rules from the unaudited cluster:
+
+| Rule | Cross-refs |
+|------|------------|
+| `never-be-idle.md` | 3 memory |
+| `razor-discipline.md` | 2 research + 2 memory |
+| `mechanical-authorization-check.md` | 1 backlog-row file + 1 research + 1 memory + 1 backlog ID (B-0160, same file as row-file ref) |
+| `wake-time-substrate.md` | 0 concrete file refs — references 4 `.claude/<surface>/` directory paths as discoverable surfaces |
+
+### Audit findings
+
+| Category | Count | Status |
+|----------|-------|--------|
+| Concrete file refs (deduplicated, B-0160 row counted once) | 10 | 10/10 LIVE |
+| Surface directory paths (`.claude/skills/`, `.claude/agents/`, `.claude/commands/`, `.claude/rules/`) | 4 | 4/4 LIVE |
+| Backlog ID (B-0160) — already counted as file path | 0 net | n/a |
+
+**14/14 testable refs LIVE.**
+
+Dedup discipline (per Codex catch on PR #3179): B-0160 appears as both a `docs/backlog/P0/B-0160-...md` file path AND as a `B-0160` ID ref; count once.
+
+## Verify (step 4)
+
+`test -e <path>` for files; `test -d <path>` for surface dirs; cross-checked the B-0160 deduplication.

+## Notes for future-Otto
+
+**`wake-time-substrate.md` is a meta-rule** with no concrete file references — it describes the discipline of landing learnings on discoverable surfaces (`.claude/skills/`, etc.) but doesn't reference specific instances. That's correct shape for a meta-rule; the audit treats it as "all discoverable surfaces exist" → LIVE.
+
+**Dedup discipline confirmed**: B-0160 was referenced twice (file path + ID); count once. The Codex catch on PR #3179 was instructive — apply it forward consistently.
+
+**Parallel-Otto branch-state contamination, again**: this tick's initial `git checkout origin/main` was blocked because the working tree was on yet another parallel-Otto local branch (`chore/b-0515-architecture-as-externalization-target-shift-2026-05-14`). Resolved via `git checkout -f origin/main` then fresh shard branch. The pattern keeps recurring — the maintainer's single worktree is a multi-Otto coordination point, and branch-state drifts under contention. Mechanization candidate (composes with B-0506): a per-tick "start with a clean origin/main checkout" wrapper.
+
+**Halfway-plus**: 28/50 (56%) means ~6 more 4-rule batches would complete item 4 coverage. At the current cadence (1 batch per tick), that's another hour of audit work.
