 # Changelog

+## [1.37.18] — 2026-08-14
+
+### Fixed
+
+- Coach reminders tied to a moment ("remind me when I next log blood pressure", "next time I open the app") now actually fire. The app has offered these since v1.22 and confirmed them, but nothing ever evaluated them; a matching measurement or the next app open now surfaces the reminder, and the daily sweep backs it up.
+- The Apple Health import tells you what it skipped and why. Every dropped sample class is now listed on the import card: unknown types, out-of-range values, deferred records, and cycle samples that were read while cycle tracking is switched off, which previously vanished without a trace. A cycle write that fails halfway also reports the failure instead of claiming zero samples.
+- Deleting a measurement now reaches the pre-computed aggregates. Before, a deleted reading stayed inside day, week, month and year statistics forever; the freshness probe can now see tombstones, and the WHOOP deletion webhook recomputes the affected days.
+- The sleep history repair job only deletes what it can restore. It used to clear a provider's entire sleep history and re-import just 30 days; the delete is now bounded to the same window.
+- The connector token settings said tokens are read-only while offering a write toggle on the same card. The copy now tells the truth in all six languages.
+- A lab report cannot smuggle instructions into the AI layer through a biomarker name anymore; document-derived names are cleaned before they reach any prompt, and the assistant tools fence checkup labels and lab analyte names the same way.
+- Google Health and Withings syncs now refresh the server-side caches like every other integration, so analytics pick up synced data on the next read instead of waiting out the cache lifetime.
+- The vaccination booster and suggestion endpoints are published in the API description, as the contract notes already claimed.
+- On phones, the Medications tab no longer appears in the bottom bar when the medications module is switched off; tapping it used to open an empty page.
+- The import guide links point at the documentation site instead of a page that does not exist.
+- A caregiver settings toggle that has had no effect since its feature was retired is gone.
+- Every create and update request from the app now carries an idempotency key, so a network retry cannot write a vaccination or an appointment twice.
+- The service worker's offline fallback version is anchored to the release version again; it had silently stayed behind for two releases.

+/**
+ * Context-cue evaluation for Coach reminders (`triggerKind: "context"`).
+ *
+ * The capture grammar has advertised four cues since v1.22 —
+ * NEXT_BP_LOGGED / NEXT_WEIGHT_LOGGED / NEXT_SLEEP_LOGGED /
+ * NEXT_APP_OPEN — and the resolver persisted them, but no evaluator
+ * existed: the user got a confirmation for a reminder that could never
+ * fire. This module is that evaluator.
+ *
+ * Two triggers, both converging on the same surfacing transaction the
+ * date sweep uses (`reminder-surface.ts`):
+ *
+ *   - `"measurement"` — the three logging cues. Called by the
+ *     `reminder-satisfy` worker right after any measurement ingest (the
+ *     same eventful hook that auto-resolves Vorsorge reminders), and once
+ *     a day by the Coach-reminder sweep as the idempotent backstop. A cue
+ *     is satisfied by EVIDENCE, not by the caller's claim: a live row of
+ *     a matching type must exist that was LOGGED (row `createdAt`, not
+ *     `measuredAt` — back-dating an old paper reading still counts as
+ *     logging) after the reminder was captured.
+ *
+ *   - `"app-open"` — NEXT_APP_OPEN. Evaluated on the nudge-status read,
+ *     the cheapest request that fires exactly when the app chrome mounts.
+ *     A capture-time grace keeps the reminder from firing into the very
+ *     session that created it: "next time you open the app" must not
+ *     mean "in the message list you are already looking at". After
+ *     surfacing the row leaves the candidate set (`status: "surfaced"`),
+ *     so the steady-state cost per read is one indexed query returning
+ *     zero rows.
+ *
+ * Server-only — reads `@/lib/db`-shaped clients (injected).
