docs(planning): record Wave 6 reconcile + v1.4.23 backlog

11 reconcile commits across Sessions A/B/D/E/F closed 1 CRIT and
all 9 HIGH findings. STATE.md ticks Wave 6; v1423-backlog.md
captures the deferred MED + LOW items + the settings-cog-vs-thumbs
debate for v1.4.24.

+Closes the multi-agent QA + Product-Lead review pass for v1.4.23.
+11 atomic commits across 5 sessions (A, B, D, E, F) collapse the
+six-review brief into shippable develop-branch state.
+
+## Per-session SHA chain
+
+| Session | Scope | Commit SHAs |

+## Counts
+
+- **CRITICAL** — 1 of 1 applied (Session A).
+- **HIGH** — 9 of 9 applied (Sessions A/B/D/E).
+- **Simplify** — 4 of 5 applied (S-01 through S-04 in Session B);
+  S-05 deferred to v1423-backlog.md (touched too many call sites for
+  a single reconcile commit).
+- **MEDIUM** — 3 applied (Session F); remainder deferred.
+- **LOW** — 0 applied; all triaged into v1423-backlog.md.
+- **Product-Lead recommendations** — adopted into v1.5 P1 prep notes
+  (filed in the next milestone's planning queue, not v1.4.23 backlog).

+| Session E close (HIGH 7 + coach-feedback updates) | 2235 |
+| Session F close (forged X-Device-Id regression) | **2236** |
+
+Net delta over the W6 reconcile arc: **+13 unit tests**.
+
+## Items routed to v1423-backlog.md
+
+See `.planning/v1423-backlog.md` for line-by-line context. Headline:
+
+- Settings-cog vs per-message-controls debate (Design pushback).
+- Pearson rigorous incomplete-beta replacement (Senior-dev review).
+- Sec-MED-1 — `apns_token` partial UNIQUE index (defence-in-depth).
+- All four security LOWs (intra-batch duplicate accounting; idempotency
+  422 cache hint; APNs key-file path leak; refresh-token failure audit
+  missing userId).
+- All review LOWs from the other five briefs (code, design, senior-dev,
+  simplify, product-lead).
+- S-05 simplify deferral (Session B).
+- Pre-existing `coach-prefs.test.ts` integration NextRequest URL mock
+  issue (Session A flag — predates v1.4.23).
+- Sandbox `git commit` silent no-op (Session H7 flag — candidate for a
+  `.claude/settings.json` permission tweak).
+
+## Cross-link to v1.4.24
+
+The v1.5 marathon prep work surfaced during Wave 6 product-lead review
+(iOS first-launch P1 plan, Coach feedback ingestion analytics, settings
+debate resolution) lives in the v1.5 backlog. The v1423-backlog.md is
+the v1.4.24 starting queue.
+
+## Wave 6 status
+
+Wave 6 closed at `1a46bfe` + this planning commit. Wave 7 (release) is
+next: pre-release verify → version bump → release-merge develop → main
+→ tag → GHCR build → Coolify deploy → production smoke.

+# v1.4.23 backlog — items deferred during the W6 reconcile
+
+Captured at the close of Wave 6 (2026-05-11). Each line points at the
+review brief that surfaced it so the v1.4.24 marathon can pick up
+without re-reading the full review pack.
+
+## Design
+
+- **Settings-cog vs per-message-controls debate** — Design pushback
+  during W6 raised concern that the v1.4.23 dual surface (per-message
+  thumbs in `<MessageThread>` AND a global tone/verbosity sheet behind
+  the settings cog) duplicates intent. Defer to v1.4.24 once W5 H7
+  surfaces enough thumbs data to know whether per-user prompt prefs
+  drift from per-message ratings. Source: `phase-W6-v1423-design-review.md`
+  + `phase-W6-v1423-product-lead-review.md`.
+
+## Statistics
+
+- **Pearson rigorous incomplete-beta replacement** — the v1.4.23 patch
+  raised `MIN_PAIRED_N` from 14 → 20 (W5 H6) as a conservative
+  surfacing-gate fix. The full normal-approx → incomplete-beta
+  replacement still wants doing; data is at the precision limit for
+  small-sample correlations. Source: `phase-W6-v1423-senior-dev-review.md`.
+
+## Security MEDs not applied in commit 1
+
+- **MED-1** — `apns_token` partial UNIQUE index. App-layer guard works
+  today; defence-in-depth at the DB layer wants a follow-up migration
+  with a `CREATE UNIQUE INDEX … WHERE apns_token IS NOT NULL`. Source:
+  `phase-W6-v1423-security-review.md` MED-1.
+
+## LOWs (all 4 reviews, deferred)
+
+- **Sec-LOW-1** — intra-batch duplicates report `inserted` for both
+  rows (only 1 actually persists). Self-inflicted accuracy bug, no
+  cross-user impact. Fix: dedupe `prepared[]` by `${type}::${externalId}`
+  before the `existing` lookup; add regression test in
+  `tests/integration/measurements-batch.test.ts`.
+- **Sec-LOW-2** — `withIdempotency` caches the 422 "batch too large".
+  Documented contract; surface a "retry with fresh key" hint in the
+  error message + OpenAPI 422 description.
+- **Sec-LOW-3** — APNs key-file read failure leaks the absolute path
+  into the wide-event payload. Replace `${message}` with redacted
+  `meta: { errno: err.code }`.
+- **Sec-LOW-4** — `auth.token.refresh.failed` audit row omits `userId`
+  even when resolvable (`already_used`/`expired`/`revoked` paths know
+  the row). Extend `RotationResult.failure` to carry the resolved
+  userId.
+- **Code-review LOWs** — see `phase-W6-v1423-code-review.md` for the
+  full list (style nits, missing JSDoc on 2 helpers, unused import in
+  `coach-drawer.tsx`).
+- **Senior-dev LOWs** — see `phase-W6-v1423-senior-dev-review.md`.
+- **Design LOWs** — see `phase-W6-v1423-design-review.md`.
+- **Product-Lead LOWs** — see `phase-W6-v1423-product-lead-review.md`.
+
+## Simplify deferrals
+
+- **S-05** — deferred from Session B; see Session B notes in
+  `phase-W6-v1423-reconcile-report.md` for rationale (touched too many
+  call sites for a v1.4.23 reconcile commit).
+
+## Test infrastructure
+
+- **`coach-prefs.test.ts` integration NextRequest URL mock issue** —
+  pre-existing failure flagged by Session A. Re-running with the
+  reconcile changes stashed reproduces the same failure, so the cause
+  predates v1.4.23. Needs investigation into how `NextRequest`'s URL
+  parsing interacts with the test harness's mocked `cookies()`.
+
+## Tooling / harness
+
+- **Sandbox `git commit` silent no-op** — Session H7 agent observed
+  `git commit` returning success without a SHA in sandboxed mode under
+  certain hook configurations. Candidate for a `.claude/settings.json`
+  permission tweak (allow `git commit` unconditionally OR add a
+  pre-flight `git status --porcelain=v1 -z` confirmation step).
