+
+## Speculative work picked
+
+The B-0090.x series collisions (4 of them) all came from one
+shape — Riven's 2026-05-10 ts-* atomic decomposition vs the
+2026-05-11 second decomposition (3-bucket-taxonomy / worktree-delta
+/ closed-not-merged-PR-scan / cadence-hook). The parent body
+matches the second set verbatim → external-references rule clear.
+
+Batched all 4 renumbers into one PR (#3058) since they share the
+same internal dependency chain — renumbering as a unit preserves
+the `depends_on: [B-0090.1]` chain by remapping to `.5`. Doing
+them one at a time would have required either temporary chain
+breakage or 4 separate dependency-update commits.

+## Substrate-level effect

+Inline duplicate-ID count on the branch:
+
+| Before #3058 | After #3058 merges |
+|---|---|
+| 11 dup groups | 7 dup groups |
+
+B-0451 cleanup progress: 1/12 → 5/12.
+
+Remaining 7 groups: B-0370/0371/0372/0373 (4 cross-priority bleed),
+B-0409 (3-way), B-0410, B-0411.
+
+## Procedure scaling observation
+
+The B-0068.1 fix (PR #3057) took ~1 file change. The B-0090.x batch
+(this PR) took 4 file changes + internal-ref remapping. The
+B-0409 3-way collision will take ~3-4 file changes. The pattern
+scales linearly with collision-group size; no single collision
+exceeds ~10 minutes.
+
+A future agent could batch all remaining 7 collisions into ONE
+PR if desired (faster), or 7 separate PRs (more focused review).
+Either path leads to dangling-dep-refs = 0 + duplicate-IDs = 0.

+
+## CI-failure triage on PR #3058
+
+9 failing checks at tick start. Most are GitHub-API-rate-limit
+exhaust (same class as previous tick), BUT one is a real lint
+failure I'm responsible for:
+
+```
+docs/hygiene-history/ticks/2026/05/13/2348Z.md:41 error MD032/blanks-around-lists
+[Context: "- `id:` updated to new sub-row..."]
+```
+
+The 2348Z shard had `Each row:` immediately followed by `- id: ...`
+with no blank line. Same failure mode I caught on the 2228Z shard
+(PR #3044, MERGED), which suggests the discipline is in-head but
+not mechanized.

+| `docs/hygiene-history/ticks/2026/05/13/2348Z.md:41` | PR #3058 `1b4866e` | Insert blank line before list (one-line fix) |
+
+## Discipline mechanization observation (for future ticks)
+
+This is the second MD032-on-tick-shard catch this session. Per
+`.claude/rules/encoding-rules-without-mechanizing.md`: encoding the
+discipline without mechanizing produces a memory of failures, not
+prevention. The mechanization options:
+
+1. **Pre-commit hook** that runs markdownlint on staged `.md` files
+   (would catch this BEFORE push; needs local markdownlint install)
+2. **Shard-writer assistant** that pre-validates blank-lines-before-
+   lists (could be a tiny TS helper)
+3. **CI-as-discipline**: accept the cost of one CI cycle to catch +
+   one cycle to land the fix (current pattern)
+
+Option 1 has the best ratio (cheap; catches the failure earlier in
+the loop). Option 3 is what the substrate currently uses and works,
+but burns ~10min CI for each occurrence.
+
+Filing as observation in this shard; no separate B-NNNN row this
+tick (scope-discipline — don't expand session beyond closing out
+the in-flight work).
