 ## [Unreleased]
 
+## [1.32.0] — 2026-07-22
+
+- **Provider ingestion and daily reactions now preserve the correct identity.**
+  Arrival reactions are bound to the exact marker revision, workout selection
+  matches field donors to the correct surviving session, long-range buckets
+  honor the user's timezone, MCP pages stay stable, and one Withings
+  subscription repair can no longer block fallback polling for other users.
+- **Large reads and writes are bounded end to end.** Measurement exports stream
+  in pages without splitting sleep sessions, oversized projections cannot evict
+  the shared cache, dense reports and metric series use database aggregation,
+  upload reads have byte, time, and concurrency limits, full-history backfills
+  share admission control, and medication imports use durable chunks with
+  resumable, bounded final rollups.
+- **Capture and history flows are complete on mobile and desktop.** Workout
+  history loads beyond the first page, metric pages open preselected capture
+  forms and return to their origin, failed water submissions retain their draft,
+  and confirmed discards clear it.
+- **Interactive forms share one safe dismissal contract.** Dirty forms require
+  confirmation across tracked Back and Forward traversals, Apple Health setup
+  exposes successful native syncs, document selection is consumed on Coach
+  dismissal but preserved across full-page Coach navigation, conversation
+  titles can be renamed with rollback, and hidden tabs refresh meaningful
+  server state.
+- **Accessibility coverage now exercises representative authenticated routes,
+  themes, dialogs, and sheets.** Small text keeps compliant contrast, OCR uses a
+  visible labeled control, workout sections use real headings, and compact
+  actions retain 44-pixel touch targets.
+- **Client and API boundaries are explicit.** Localized stable error codes cover
+  measurement, mood, lab, and onboarding failures; client fetches and query
+  keys are lint-enforced; AI overrides are documented; and large Coach,
+  report, target, and provider modules now use one-way focused builders.
+
+- **Production image processing uses the patched Sharp 0.35 runtime.** This
+  closes the current high-severity libvips advisory chain inherited through
+  Next.js while retaining verified production-build compatibility.
+
+Migrations `0264_whoop_owner_identity`, `0265_withings_subscription_state`, and
+`0266_medication_intake_import_jobs`. No breaking changes.

+ * A raw `fetch(...)` in a client module can hide a same-origin API request
+ * behind a variable, endpoint map, or conditional. Checking only literal
+ * `/api/...` arguments therefore leaves the envelope and error contract open
+ * to bypass. This rule rejects every bare Fetch API call in the client surface,
+ * regardless of argument shape.
  *
- * Complements `healthlog/safe-fetch-required`: that rule covers
- * OUTBOUND egress (absolute / variable-sourced URLs) and exempts
- * same-origin relative paths; this rule covers exactly those same-origin
- * `/api/...` paths inside the client surface.
+ * Use `apiGet` / `apiPost` / `apiPut` / `apiPatch` / `apiDelete` for envelope
+ * JSON. Use `apiFetchEnvelope` when success metadata is required, and
+ * `apiFetchRaw` for deliberate Response-level work such as external requests,
+ * downloads, streams, beacons, or manual status branching.
  *
- * Allowed:
- *   - `apiFetch` / verb helpers / `apiFetchEnvelope` / `apiFetchRaw` —
- *     distinct identifiers, never match.
- *   - calls inside `src/lib/api/api-fetch.ts` — the wrapper's own `fetch`.
- *   - test files (`*.test.ts(x)`, `__tests__/`, `__mocks__/`) — they
- *     mock or assert against `fetch` directly.
- *
- * The check is a syntactic `CallExpression` match against a bare
- * `fetch(` callee (Identifier `fetch`) and `globalThis.fetch(` /
- * `window.fetch(` / `self.fetch(` member forms, where the first
- * argument is a string literal or template literal whose head starts
- * with `/api/`. Variable-sourced or absolute URLs are the
- * safe-fetch-required rule's territory and stay out of scope here.
+ * Components and hooks are client-facing by convention. Other `src/` modules
+ * are guarded when they declare top-level `"use client"`; `src/lib/queries/`
+ * remains an explicit client-transitive root. Server-only modules, tests,
+ * mocks, and the wrapper implementation are exempt.
