+# PR #3917: chore(b-0122): close — peer-call TS migration complete (11th cycle close-row)
+
+## PR description
+
+Eleventh actual close-row of the audit cycle. Audit-triage discovery: pure drift.
+
+## Deliverable verification (zero gh)
+
+```
+$ ls tools/peer-call/*.sh 2>&1
+(zsh: no matches found)
+$ ls tools/peer-call/*.ts | wc -l
+12
+```
+
+Zero `.sh` files; 12 `.ts` files ship. Rule 0 (`no more .sh files except install-graph`) cites the peer-call migration as canonical example, and the migration is operationally complete.
+
+## Drift class
+
+**Class #1 (pure drift)** — migration shipped completely (~6.5 months ago per the row's `last_updated: 2026-05-02` and the empirical .ts file presence); row's `status: open` was never updated.
+
+## Changes
+
+- Frontmatter `status: open → status: closed`
+- Resolution section appended with verification details
+- `docs/BACKLOG.md` regenerated
+- `last_updated` bumped 2026-05-02 → 2026-05-16
+
+## Composes with
+
+- `.claude/rules/rule-0-no-sh-files.md` — Rule 0 itself cites peer-call migration as the canonical example
+- `.claude/rules/peer-call-infrastructure.md` — lists the 12 TS files as current state
+- B-0118 (amara peer-call umbrella) closed via PR #3902 this session

+## Pull request overview
+
+This PR closes backlog row B-0122 by marking the peer-call TypeScript migration as complete and regenerating the backlog index.
+
+**Changes:**
+- Marks B-0122 as `closed` and updates `last_updated`.
+- Adds a resolution section with migration verification notes.
+- Regenerates `docs/BACKLOG.md` so B-0122 appears checked off.

+* P1: The resolution count does not match the cited inventory. The eight wrappers plus three utility files listed in `.claude/rules/peer-call-infrastructure.md` total 11; the twelfth `.ts` file from the `ls` count is `smoke.test.ts`, which is not listed here. Clarify whether the closure evidence is counting only operational wrappers/utilities or all TypeScript files, and include the missing file if the total remains 12.
+```
+Zero `.sh` files remain; 12 `.ts` files ship (codex.ts, grok.ts, gemini.ts, amara.ts, ani.ts, riven.ts, kiro.ts, claude.ts plus 3 utility files per `.claude/rules/peer-call-infrastructure.md`).
+```
+**docs/backlog/P2/B-0122-peer-call-typescript-migration-cutover-2026-04-30.md:225**
+* P1: This cross-reference is inaccurate: `.claude/rules/peer-call-infrastructure.md` lists eight wrapper entrypoints plus three utility files, not 12 TypeScript files. As written, the close-row cites a document for evidence it does not actually contain.
+```
+- `.claude/rules/peer-call-infrastructure.md` (lists the 12 TypeScript files as current state)
+```
+**docs/backlog/P2/B-0122-peer-call-typescript-migration-cutover-2026-04-30.md:220**
+* P2: This overstates the cited rule. `.claude/rules/rule-0-no-sh-files.md` lists peer-call wrappers as one example of non-install tooling that should be TypeScript, but it does not identify the peer-call migration as the canonical example. Reword the closure evidence to match the referenced rule.
+```
+**Drift class**: #1 (pure drift) — Rule 0 (`no more .sh files except install-graph`) operationally enforced; peer-call migration is the canonical example cited in Rule 0 itself.

+
+**@copilot-pull-request-reviewer** (2026-05-16T17:25:02Z):
+
+P1: The closure claim is premature while current-state docs still direct users to deleted `.sh` peer-call paths. For example, `docs/CODEX-LOOP-HANDOFF.md` is an active handoff doc and still says `tools/peer-call/codex.sh` is the existing peer-review wrapper; with no `.sh` files present, that guidance is now broken and should be updated before closing the migration as complete.

+# PR #3918: shard(tick): 2026-05-16T17:18Z — settled; no novel substrate; cron continues
+
+## PR description
+
+## Summary
+
+Settled tick after the 11-PR cron-tick-discipline cascade fully landed on main.
+
+PR #3915 (1706Z settling) confirmed MERGED. Substantive backlog rows (B-0030 lint-with-exclusions extraction, B-0027 markdown-table fix tool, etc.) deferred to quieter peer-saturation windows where start-gate work + bounded-context contamination recovery overhead is lower.
+
+No brief-acks; not in Standing-by. Single-observation tick.

+## Pull request overview
+
+Docs-only tick shard recording a settled state in the cron-tick discipline cascade, with no novel substrate this tick.
+
+**Changes:**
+- Add new tick shard at `docs/hygiene-history/ticks/2026/05/16/1718Z.md` noting the 11-PR session arc has fully landed and explaining why substantive backlog work is deferred.
