+## [1.11.0] — 2026-06-04 — WHOOP, a longitudinal coach, and a clinician-grade record
+
+A multi-feature milestone across three fronts: a second connected provider, deeper Insights, and a shareable clinical record.
+
+### Added
+
+- **WHOOP integration.** Connect a WHOOP account with your own developer keys to bring its recovery, day- and workout-strain, sleep-performance, HRV (RMSSD), and energy readings into HealthLog alongside Apple Health and Withings — synced on a schedule and via signed webhooks, each value kept distinct by its source so it never overwrites a reading from another device.
+- **A longitudinal Insights coach.** A weekly/monthly narrative summarises what changed over the period and the likely contributing factors (descriptive, never causal); the Coach now carries a rolling profile of your recent baselines and trends; and a short-horizon trajectory projection shows where a metric is heading with an honest, widening confidence band — shown only when there is enough history to mean something.
+- **A clinician-grade health record.** A read-only FHIR REST API (`GET /api/fhir/*`) serves your data as standard FHIR R4 resources, and you can mint a scoped, time-limited, revocable share link that opens a clean read-only clinician view — no account needed. Wellness figures stay fenced off from the clinical ones with a plain "not a clinical assessment" note.
+- **More resilient AI generation.** A durable provider-health record skips a known-bad credential instead of failing every run and surfaces an expired credential proactively, with a local model as a guaranteed fallback.
+
+### Known limitations (planned follow-ups)
+
+- When two sources supply the same standard vital (e.g. WHOOP and an Apple Watch both report resting heart rate), both readings may currently appear for a day until a source-aware aggregation update resolves them to your preferred source. WHOOP's own scores are unaffected; a note explains this on the WHOOP card.
+- The coach reflects your rolling health profile and trajectory; full conversation-summary memory and saved personal facts are a later refinement.

 ## What it is
 
-HealthLog is a self-hosted personal health tracker that runs from a single `docker compose up`. It covers the metrics most people actually log -- weight, blood pressure, pulse, body composition, blood glucose, sleep, mood, and medication compliance -- and brings them together in one dashboard with reference ranges from ESH 2023, ADA 2024, and NICE NG115. Withings devices sync automatically; an `export.zip` import folds your full Apple Health history into the same timeline; a native SwiftUI iOS client (public-beta via [TestFlight](https://testflight.apple.com/join/bucuTBpa)) streams HealthKit live; multi-provider AI Insights (BYOK or local) explain what the numbers mean; a doctor-report PDF generates client-side. EN/DE end-to-end. AGPL-3.0.

+# WHOOP integration
+
+HealthLog connects to WHOOP via OAuth2 plus HMAC-signed webhooks for
+near-real-time sync of recovery, strain, sleep, and the underlying
+heart-rate / HRV signals. Unlike Withings, WHOOP credentials are
+brought per user: each user (or the operator on their behalf)
+registers their own WHOOP developer app and pastes the client
+id/secret into Settings.
+
+## Why bring your own keys
+
+WHOOP caps the number of users a single developer app may authorise.
+Per-user BYO-keys sidestep that per-app cap: every user authorises
+against their own WHOOP app, so a shared HealthLog instance never
+runs into one app's user ceiling. It also keeps each user's WHOOP
+grant scoped to credentials they control.
+
+## 1. Register a WHOOP developer app
+
+1. Sign in at <https://developer.whoop.com/> and create a new app.
+2. **Redirect URI:** `https://your-instance.example.com/api/whoop/callback`
+   (matches `WHOOP_REDIRECT_URI`, below). Add one entry per
+   environment you connect from.
+3. Request the scopes for recovery, cycle/strain, sleep, and the
+   workout/heart-rate reads the sync uses.
+4. Save the app. WHOOP issues a **Client ID** and **Client Secret** —
+   keep the secret out of any chat log; it grants read access to the
+   linked account's full WHOOP history.
+
+## 2. Wire the credentials in Settings → Integrations
+
+WHOOP credentials are stored per user, not in `.env`. Sign in as the
+target user, open **Settings → Integrations → WHOOP**, and paste the
+client ID and secret. They are encrypted AES-256-GCM at rest.
+
+## 3. Connect
+
+Click **Connect WHOOP**. The flow:
+
+1. The Connect button redirects to WHOOP's OAuth authorize endpoint.
+2. The user signs in on WHOOP and grants the requested scopes.
+3. WHOOP redirects back to `/api/whoop/callback` with an auth code.
+4. HealthLog exchanges the code for an access + refresh token, stores
+   them encrypted, registers the webhook, and triggers an initial
+   sync of recent history.
+5. Subsequent syncs run on every webhook delivery plus a safety-net
+   cron pull.
+
+## Optional instance env vars
+
+Two server-level env vars tune the OAuth callback and webhook
+verification. They are optional — the per-user client id/secret in
+Settings drive the connection itself.
+
+```env
+WHOOP_REDIRECT_URI="https://your-instance.example.com/api/whoop/callback"
+WHOOP_WEBHOOK_SECRET="$(openssl rand -hex 32)"
+```
+
+- `WHOOP_REDIRECT_URI` — the OAuth callback URL handed to WHOOP. Must
+  match a redirect URI registered in the WHOOP developer app.
+- `WHOOP_WEBHOOK_SECRET` — the secret HealthLog verifies the WHOOP
+  webhook HMAC signature against. WHOOP signs each webhook body; the
+  handler validates the signature before processing. Generate a fresh
+  random value and restart the `app` container after setting it.
+
+## Disconnect
+
+The Settings page **Disconnect** button revokes the stored tokens and
+removes the connection. Existing measurements synced from WHOOP stay
+in the database — disconnect does not delete data.

+--
+-- Purely-additive: two enum-extension batches, two new tables, and two new
+-- nullable columns on `users`. No backfill, no existing row touched.
+--
+--   1. `measurement_type` += seven WHOOP-native score classes. WHOOP day-strain
+--      lands in the NEW `DAY_STRAIN` (NOT the existing COMPUTED `STRAIN_SCORE`,
+--      the v1.10.3 TRIMP engine) so the native value and the derived proxy
+--      never share a bucket. The RMSSD HRV gets its own `HRV_RMSSD` for the
+--      same reason (distinct estimator from the SDNN `HEART_RATE_VARIABILITY`).
+--      WHOOP-native Recovery reuses the existing `RECOVERY_SCORE`, distinguished
+--      only by `source = WHOOP` vs `COMPUTED`.
+--   2. `measurement_source` += `WHOOP` for the server-side native ingest.
+--   3. `whoop_connections` — per-user encrypted token row (1:1 with users),
+--      mirroring `withings_connections` plus `whoop_user_id`,
+--      `backfill_completed_at`, and `max_heart_rate`.
+--   4. `whoop_oauth_states` — short-lived `(nonce → userId)` CSRF ledger,
+--      identical in shape to `withings_oauth_states`.
+--   5. `users` += `whoop_client_id_encrypted` / `whoop_client_secret_encrypted`
+--      — per-user BYO-keys (the per-app authorized-user cap makes a single
+--      shared WHOOP app unworkable for a multi-operator product).

+-- Idempotent guards (`IF NOT EXISTS`) make reruns safe. Forward-only.

+ * action all need state and mutate via the C4 lifecycle API
+ * (`/api/share-links`). Reads unwrap `(await res.json()).data`; the query key
+ * comes from the centralised factory. No markdown anywhere — every value

+ *      (mocked `prisma`) — an auth failure benches a provider for the
+ *      long cooldown, a hard failure for the short one, and a success
+ *      clears the negative cache. Multi-instance correctness is
+ *      structural (single atomic `INSERT … ON CONFLICT … DO UPDATE`),
+ *      so we assert the upsert is emitted rather than re-proving the
+ *      DB's atomicity.
+ *   2. The in-memory ledger's negative-cache semantics, which the
+ *      runner tests reuse without standing up Postgres.

+ * series and calls no model — it reads artefacts we already persist:
+ *
+ *  - `priorNarrative` — the most recent period-narrative (W3) headline +
+ *    its driver list, so the Coach can say "as I noted at the start of the
+ *    month, your resting HR drifted up" instead of re-deriving cold every
+ *    turn. Source: `readPeriodNarrative` (stale-while-revalidate read of the
+ *    typed `insight_narratives` row).
+ *  - `trendMemory` — per in-scope vital, the band it held in the PRIOR
+ *    period vs where its current-period center sits now. This generalises
+ *    the per-status `memory.ts` previous-context primitive to the Coach.
+ *    Source: the band transitions already computed by
+ *    `buildPeriodNarrativeContext` (MAD baseline, prior-period band edges).
+ *
+ * Unencrypted by the same rule as `metricSourceJson` / the derived block:
+ * it is the user's own labels + numbers + a provenance-grounded narrative
+ * recall, never free conversational content (that lives in the encrypted
+ * W5b summary). Per-source fault isolation: a transient failure on either
+ * sub-source drops that sub-block and never sinks the Coach turn.
+ *
+ * Lowest snapshot priority by design — wired into `snapshot.ts` so
+ * `degradeToBudget` sheds it FIRST under the char cap, before any clinical
+ * cluster.
+ *
+ * Server-only — reads `@/lib/db` transitively through the two sources.

+ * v1.11.0 W1 — durable provider-health ledger.
+ *
+ * Epic B Pillar 4 (resilience floor). Promotes the volatile per-worker
+ * `lastWorkingCache` in `provider-runner.ts` to a Postgres table so the
+ * fallback chain shares one health signal across every worker, exactly
+ * like the rate limiter ("rate limits live in Postgres"). The ledger is
+ * a read-through reporter layered AROUND the existing
+ * `isHardProviderFailure` classifier — it never re-decides what a
+ * failure is; it only remembers the outcome.
+ *
+ * Two jobs:
+ *   1. **Negative cache** for an auth-class failure (401/403 =
+ *      "credential dead, re-link required"). Instead of re-burning the
+ *      dead round-trip on every generation, the runner skips a provider
+ *      whose row reads `auth_failed` while `nextRetryAt` is in the
+ *      future. The cooldown is far longer than the old 1h in-memory TTL
+ *      so a single expired codex token does not silently kill every
+ *      generation for the next hour-per-worker.
+ *   2. **Proactive surfacing.** `findCredentialExpiredProviders` lets
+ *      the coach route / a health check report a known-bad credential
+ *      ("ChatGPT connection expired — reconnect") rather than leaving
+ *      the failure invisible until the next manual Coach turn.
+ *
+ * Resilience: every DB interaction is best-effort. The ledger is an
+ * optimisation, never a gate — a transient DB error must never take
+ * down generation, so reads fail open (empty result) and writes are
+ * fire-and-forget. This keeps the runner's existing behaviour the
