 ## [Unreleased]
 
+## [1.18.0] — 2026-06-16 — turn off what you don't track, and a settings menu that finally reads as one app
+
+This release makes the app yours to shape. Every optional area — cycle, mood, sleep, glucose, workouts, recovery, labs, achievements, the coach, AI insights and the doctor-report — can be turned off, and when it is, it disappears everywhere at once: out of the navigation, off the dashboard, gone from insights, the coach, your reminders, achievements and the exported report. Your data is kept; turn the area back on and it returns. The settings menu was redesigned alongside it, so notification channels, integrations, sources and per-area pages each sit where you'd look for them instead of spread across overlapping hubs. The core vitals — weight, blood pressure, pulse and medications — are always on. No breaking changes.
+
+### Added
+
+- **Turn modules on and off.** A "What you track" settings hub lets you switch off any area you don't use. The switch is honoured by one server-side gate, so a disabled area is hidden from the navigation and the dashboard and is also refused at its API — the surface and the route vanish together, with no window where one leaks without the other. Re-enabling restores everything; nothing is deleted.
+- **Operator-level module availability.** A self-hoster can make an area unavailable for the whole instance from the admin settings; an operator "off" wins over any personal preference. Both layers project onto the same module map the web app and the companion app already read, so neither client needs special handling.
+
+### Changed
+
+- **The settings menu reads as one app.** Notification channels moved under Integrations alongside the connection and source panels; the duplicated "Reminders" hub collapsed into Notifications; mood, medications and the health-record export each became a clear top-level entry; and every section now carries one consistent heading. Old deep links (`/settings/reminders`, `/settings/sources`, the standalone coach page) redirect to their new homes.
+- **One add-entry pattern across every feature page.** The cycle, labs, mood, medication and preventive-care pages now share the same header and primary "add" affordance, so a page built later doesn't read differently from one built earlier.
+
+### Operator note
+
+- Migrations 0167 (per-user module preferences) and 0168 (operator-level module availability) are additive — a single nullable JSON column each, no backfill. Both default to "all on": an area is disabled only by an explicit choice. No deploy-time action is required.
+
 ## [1.17.1] — 2026-06-15 — preventive care, lab results, and more of the data you already have
 
 This release closes the loop from tracking to acting. Preventive-care reminders tell you when to measure or check what, structured lab results give your bloodwork a home, and a new recovery view surfaces signals that were already being collected but never shown. Sleep timelines now read in real clock times, marking a dose on one device clears its reminder on the others within seconds, and self-hosters gain a generic webhook channel, email, one-tap Web Push setup and a proper notifications guide. Every new number is computed once on the server and read the same way on the dashboard, the coach, the doctor-report and the companion app. No breaking changes.

+## Agent context hygiene (ECONNRESET / oversized-request prevention)
+- **NEVER read `src/generated/**`** — Prisma-generated client (~9 MB, 83 files incl. a 224 KB+ inline schema). Reading/grepping it explodes the request context → 10-min "cogitations" + `ECONNRESET` on large turns. Regenerate via `pnpm prisma generate` if needed; never open it. (Enforced via `.claude/settings.local.json` Read-deny.)
+- Avoid bulk-reading other large artifacts: `pnpm-lock.yaml`, `CHANGELOG.md`, `messages/*.json`, `docs/api/openapi.yaml` — grep narrowly instead of full reads.
+- For very large multi-agent actions: cap concurrent sub-agents (many simultaneous streaming requests + big context is the worst combo for connection resets). When on a VPN (Tailscale MTU 1280 / iCloud Private Relay), large requests can hit MTU black-holes — disable the tunnel for heavy sessions.

-# Doctor Report
-
-The doctor report is a printable PDF summary of a user's tracked vitals,
-medication compliance, glucose context, and mood over a configurable window
-(default 90 days, max 365). It is intended as discussion material for a
-doctor's appointment, **not** a medical diagnosis.
-
-## Two endpoints
-
-The same aggregation logic backs both endpoints — `collectDoctorReportData`
-in `src/lib/doctor-report-data.ts` is the single source of truth — so the
-JSON payload and the server-rendered PDF are guaranteed to be in sync.
-
-### `POST /api/doctor-report` — JSON payload
-
-Returns the aggregated `DoctorReportData` envelope. Used by the PWA's
-client-side renderer (`src/lib/doctor-report-pdf.ts`, jsPDF + autotable).
-Best on desktop browsers and on Android, where local generation keeps the
-PDF off the wire and works offline (cached page).
-
-- Auth: session required.
-- Rate-limit: 10/h per user.
-- Body: `{ days?: number }` (default 90).
-- Response: `200 application/json` with envelope `{ data, error: null }`.
-- Audit action: `doctor-report.generate`.
-
-### `POST /api/doctor-report/pdf` — server-rendered PDF
-
-Returns the ready-to-download PDF bytes. Used primarily on iOS/Safari, where
-the client-side jsPDF download UX is unreliable (Safari sometimes opens the
-PDF in a new tab without preserving the filename or fails the blob save).
-
-- Auth: session required (`401` otherwise).
-- Rate-limit: 10/h per user, shared with the JSON endpoint (`429` on excess).
-- Body: `{ days?: number; locale?: "de" | "en" }`. Body is optional — empty
-  bodies are accepted.
-- Locale resolution: explicit `body.locale` wins, then the
-  `Accept-Language` header (`de*` → `de`, anything else → `en`), then the
-  hard fallback `de`.
-- Response: `200 application/pdf` with
-  `Content-Disposition: attachment; filename="healthlog-report-YYYY-MM-DD.pdf"`
-  and `Cache-Control: no-store`. Body is the raw PDF bytes.
-- Errors: JSON envelope `{ data: null, error: "..." }` for `401` and `429`;
-  `500` if rendering fails.
-- Audit action: `doctor-report.pdf.generate`.
-
-## Wellness summary (derived scores)
-
-Since v1.10.0 the report carries a **Wellness summary** section below the
-clinical content, holding the server-derived wellness scores (Recovery,
-Stress, Strain) and the other derived metrics where present. It is kept
-deliberately separate from the clinical vitals table:
-
-- Each entry is labelled **descriptive, not a clinical assessment**, and the
-  scores never enter the vitals table or the clinical aggregations.
-- The Stress score is shown as an HRV-derived proxy, not a sensor-measured
-  stress value.
-- In the FHIR export the same scores are emitted as `survey`-category
-  `Observation`s (text-only `code`, no fabricated LOINC) with a per-Observation
-  non-clinical note — so a downstream system never mistakes them for a vital
-  sign or a diagnosis.
-
-Each derived metric states its inputs, method, and the cited standard it is
-grounded in (the same provenance the in-app explainer shows).
-
-## Implementation notes
-
-- `src/lib/doctor-report-pdf-core.ts` contains the isomorphic renderer.
-  jsPDF runs unchanged in Node — `doc.output("arraybuffer")` returns a valid
-  `%PDF-` byte stream in both environments, so we deliberately avoid headless
-  Chromium (Puppeteer/Playwright) to keep the runtime dependency surface low.
-- `src/lib/doctor-report-pdf.ts` is a thin client façade that returns the
-  raw `jsPDF` instance so the existing settings-page download flow (which
-  calls `doc.save(...)`) keeps working unchanged.
-- Server-side translations come from `messages/{de,en}.json` via
-  `getServerTranslator()` (`src/lib/i18n/server-translator.ts`).

+/**
+ * v1.18.0 — module API route gate inventory.
+ *
+ * The v1.18.0 module retrofit can hide a toggleable module across the
+ * nav, dashboard tiles, Insights pills, reminder jobs, doctor-report
+ * sections, and the AI surfaces. The ONE server-side enforcement point
+ * is `@/lib/modules/gate` — `requireModuleEnabled(userId, key)` in API
+ * routes, `isModuleEnabled` / `resolveModuleMap` in builders + jobs +
+ * components. Without a discovery test, a future contributor who lands a
+ * new per-domain route for a toggleable module (a new mood-analysis read,
+ * a new sleep view, a new glucose panel) would have to remember the gate
+ * by hand. A silent miss leaks the surface over a Bearer token even when
+ * the account — or the operator — turned the module off.
+ *
+ * This test walks every per-domain route tree that serves a TOGGLEABLE
+ * module and pins each `route.ts` into exactly one of these buckets:
+ *
+ *   1. MODULE-GATED — the file calls `requireModuleEnabled(...)` for the
+ *      right key (mood / sleep / glucose / workouts / recovery / labs /
+ *      achievements). This is the direct gate.
+ *
+ *   2. DELEGATED — the module's enabled-state is owned elsewhere and the
+ *      route gates on that single source of truth instead of re-deriving
+ *      it (no double source of truth, mirroring the registry's
+ *      `delegatesTo`):
+ *        - cycle  → `requireCycleEnabled(...)` (the cycle gate the
+ *                   `cycle` ModuleKey delegates to).
+ *        - coach  → `requireAssistantSurface("coach")` (the assistant
+ *                   master flag + per-user opt-out the `coach` ModuleKey
+ *                   delegates to). Covered in depth by the sibling
+ *                   `coach-route-gate-inventory.test.ts`; listed here so
+ *                   coach-bearing routes are not flagged as ungated.
+ *
+ *   3. BUILDER-GATED — the route delegates its whole payload to an
+ *      aggregator that resolves `resolveModuleMap(userId)` once and
+ *      excludes disabled-module sections/resources from the build
+ *      (`collectDoctorReportData`, `loadFhirContext`). The exclusion is
+ *      structural at the builder, so the route carries no per-key call.
+ *
+ *   4. EXEMPT — an explicit, COMMENTED allowlist of routes that serve a
+ *      toggleable domain but are deliberately NOT gated, each with the
+ *      reason at the entry. The two reasons in play:
+ *        - DATA LAYER: raw CRUD over the domain's own rows. Writing or
+ *          reading a disabled module's data is harmless — the module gate
+ *          governs whether the domain SURFACES (nav, tiles, analysis,
+ *          reports), not whether the row store accepts writes. Disabling
+ *          a module must not wedge an importer / sync / the user's ability
+ *          to clean up data, and re-enabling must find the data intact.
+ *        - INFRA / UI-ONLY: settings, availability probes, and the static
+ *          FHIR CapabilityStatement carry no module data.
+ *
+ * Anything that doesn't fit one of the four buckets is an orphan and
+ * fails the test BY NAME so the fix is one search-and-add: gate the route
+ * or move it onto the EXEMPT allowlist with a documented reason.
+ */
+
+/**
+ * The per-domain route trees that serve a toggleable module. Each entry
+ * is a directory under `src/app/api`; every `route.ts` beneath it is

+ * The SECOND layer of the two-layer module model. A module the operator
+ * turns off here is off for EVERY account regardless of that account's
+ * personal preference — mirroring the coach master flag
+ * (`assistant_coach_enabled`) sitting above the per-user

+ * already projects the resolved (operator AND user) map, so web + iOS need
+ * no extra logic.
+ *
+ * Dedicated endpoint (separate from the generic `/api/admin/settings`)
+ * so the admin panel can wire an optimistic matrix against a focused
+ * request/response shape and the audit trail carries a single
+ * `admin.settings.module-availability.update` action.
+ *
+ * Request shape — a partial DISABLED-allowlist patch keyed by toggleable
+ * module key; every field optional; `true` ⇒ available, `false` ⇒ disabled
+ * server-wide:
+ *
+ *   { "mood": false, "glucose": true }
+ *
+ * Core domains (weight, BP, pulse, medications) are NOT module keys; the
+ * `.strict()` schema rejects them, so the measurement engine + meds can
+ * never be disabled through this route.
+ *
+ * `requireAdmin()` gates the route — cookie-only by construction; a Bearer
+ * token (even `["*"]` scope) cannot reach it.

-/**
- * Doctor-report export dialog (v1.4.15 phase B6 + v1.4.25 W6c).
- *
- * Wraps the trigger button so the user picks:
- *   1. Reporting period (date range, with three presets).
- *   2. Practice / clinic name (optional, persisted between exports).
- *   3. Which data sections appear in the PDF (per-user persisted toggles).
- *
- * Hide-when-empty (the maintainer 2026-05-14): a section's toggle is only shown
- * when the selected date range actually has data for it — checking a box
- * for an empty section would produce a silently-empty PDF page. The
- * availability probe runs on every range change via
- * `/api/doctor-report/availability`.
- *
- * Privacy default: mood is OFF by default per the maintainer — mental-health data
- * is opt-in even within a single user's own surface. The API layer
- * filters mood out of the report payload server-side when the toggle is
- * off, so the data never leaves the DB row.
- *
- * Defaults:
- *   - end   = today
- *   - start = today − 90 days
- *   - sections = persisted prefs OR documented defaults
- *
- * Validation runs in the client so the dialog can show inline errors
- * without bouncing through the server. The server still re-validates via
- * `normaliseDateRange()` (silent fallback to last-90-days) — the client
- * messages are UX, not security.

+ * to the resolved module map (`useAuth().user.modules`), plus a read-only
+ * "always on" group for the four core domains. Flipping a toggle PATCHes
+ * `/api/auth/me/modules` (a DISABLED allowlist) and invalidates the
+ * `authMe()` query so nav / pills / tiles re-gate live.

+ * Test strategy mirrors `advanced-research-mode.test.tsx`: mock
+ * `@tanstack/react-query` so the rendered tree executes under SSR
+ * (`renderToStaticMarkup`), capture the `useMutation` config to assert the
+ * PATCH body + the `authMe()` invalidation directly, and mock `useAuth` to

+/**
+ * `<ModuleToggleRow>` — one row in the Settings → Module ("Was du trackst")
+ * hub. v1.18.0.
+ *
+ * Renders a single module: a neutral icon, the i18n label + one-line
+ * description, and a `<Switch>` reflecting the resolved enabled-state. The
+ * row is presentation-only — the parent `<ModulesSection>` owns the mutation
+ * and cache invalidation, so this component stays a pure, easily-tested leaf.
+ *
+ * Four modes:
+ *   - toggleable: the Switch is live; flipping it calls `onToggle(next)`.
+ *   - locked (core domains): the Switch is checked + disabled with a short
+ *     "always on" note, so the always-on measurement engine + meds read as
+ *     deliberately fixed rather than broken.
+ *   - managed elsewhere (delegated modules cycle/coach): no Switch at all —
+ *     the real on/off lives in another section, so the row renders a
+ *     read-only deep-link ("Manage in X") rather than a dead toggle that
+ *     no-ops and snaps back behind a misleading "saved" toast.
+ *   - operator-disabled: the operator turned the module off server-wide, so
+ *     the Switch is replaced by a read-only "disabled server-wide" note —
+ *     a per-user toggle could not re-enable it anyway.
+ *
+ * Palette stays neutral throughout — no alarming green-when-on /
+ * red-when-off tint.

+ * separate "Erinnerungen" hub that only deep-linked into the canonical editors
+ * ("doppelt gemoppelt"). The hub is gone (its route 301-redirects here); the
+ * reminder TYPES now live centrally on this one screen.
+ *
+ * Each reminder-type card is shown ONLY when its module is enabled, read from
+ * the resolved `useAuth().user.modules` map (the same `/auth/me` map nav and
+ * Insights pills gate off). Mood → `mood`, Coach nudge → `coach`. Low-stock
+ * runway maps to the medications CORE domain, so it is always shown. Vorsorge
+ * (preventive-care) reminders are not a toggleable module, so they are always
+ * shown. The gate fails OPEN: a missing key reads as enabled, so a stale
+ * `/me` payload never blanks a card.
+ *
+ * Delivery CHANNELS (Telegram / ntfy / Web Push / Webhook / Email) are a
+ * different concept — a channel is a delivery provider, the same family as a
+ * connected device — and live under Settings → Integrations → Channels (moved

-/**
- * v1.17.1 — the one "Reminders & Notifications" home.
- *
- * Before this section, "what gets reminded and when" was scattered across
- * three unrelated homes: medication reminders lived per-medication on the med
- * cards, mood + low-stock + coach-nudge lived inside the Notifications channel
- * screen, and the new Vorsorge (preventive-care) reminders had their own
- * page. There was no single place that answered "was erinnert mich woran,
- * wann, und worüber".
- *
- * This hub is the single front door. It draws a clean line between two
- * genuinely different concepts (so the maintainer rule "never split the same
- * concept across a page" still holds):
- *
- *   - CHANNELS — the *how/where* a reminder is delivered (APNs / Telegram /
- *     ntfy / Web Push / Webhook / Email). These keep living on the
- *     Notifications channel screen; this hub links to them.
- *   - CATEGORIES — the *what/when*: medication, mood, Vorsorge, low-stock
- *     runway, and the proactive Coach nudge. Each keeps its own canonical
- *     editor and deep link; the hub just gathers them so the concept reads
- *     as one place.
- *
- * Consolidation by linking — every existing editor stays intact and
- * deep-linkable; nothing here is a rewrite.

+ * v1.18.0 — module enable/disable → coach-snapshot domain map.
+ *
+ * When a toggleable data-domain module is disabled for the account, the
+ * domains it owns must never enter the coach context. We reuse the
+ * existing `excludeMetrics` filtering path (the `excluded` set narrows
+ * `sources` before any row is read) by folding the disabled modules into
+ * a SYSTEM-side exclusion that unions with the user's `excludeMetrics`.
+ *
+ * Each toggleable data domain maps to the `CoachScopeSource` token(s)
+ * its snapshot block(s) gate on:
+ *   - `mood`      → the mood block (`mood` source).
+ *   - `sleep`     → the per-night sleep block + the sleep-rhythm block
+ *                   (both gate on the `sleep` source).
+ *   - `glucose`   → the glucose per-context + clinical block.
+ *   - `workouts`  → the workouts block.
+ *   - `recovery`  → the recovery / strain composites. These are the
+ *                   derived block (READINESS / RECOVERY_SCORE / STRAIN_SCORE
+ *                   / …), the WHOOP-native dayStrain block, and the
+ *                   trajectory block — all gated on `derivedActive`, which
+ *                   reads HRV / resting-HR / VO₂max. Dropping those source
+ *                   tokens drops the raw additive timelines too; the
+ *                   composites are additionally gated below so they never
+ *                   build off the sleep signal alone.
+ *
+ * `cycle` is intentionally absent: its block already resolves through the
+ * fully two-layer cycle gate (`isCycleAvailableForUser` — the per-user
+ * toggle AND the operator server-wide kill-switch) below, exactly as the
+ * W1 foundation prescribes. `coach` is the surface being narrated, not
+ * a data domain. `labs` / `achievements` / `insights` / `doctorReport`

+/**
+ * v1.18.0 — module enable/disable gate.
+ *
+ * The ONE enforcement point for the module foundation. Every leak-point
+ * (nav, dashboard tiles, insights sections, coach snapshot, status
+ * routes, reminder jobs, achievements, doctor-report / FHIR, search,
+ * quick-add) resolves its decision through `isModuleEnabled(userId, key)`
+ * and `requireModuleEnabled(userId, key)`. Mirrors the cycle gate
+ * (`src/lib/cycle/gate.ts`) and the assistant feature flags
+ * (`src/lib/feature-flags/index.ts`).
+ *
+ * TWO-LAYER model (operator AND user). Every toggleable module's final
+ * enabled-state is `operatorAvailable(key) && userEnabled(key)`:
+ *
+ *   - LAYER 1 (operator): the server-wide availability allowlist on
+ *              `AppSettings.moduleAvailabilityJson`, resolved by
+ *              `getOperatorModuleAvailability()`. A module the operator
+ *              turns off is off for EVERY account regardless of personal
+ *              preference — mirroring the coach master flag above
+ *              `User.disableCoach`. Default-available.
+ *   - LAYER 2 (user): the per-account opt-out described below.
+ *
+ * Source-of-truth discipline (NO double source of truth) for LAYER 2:
+ *
+ *   - `cycle`  delegates to `isCycleEnabled(gender, CycleProfile)` — the
+ *              existing cycle gate. `modulePreferencesJson.cycle` is
+ *              ignored on purpose. Still AND-ed with operator availability.
+ *   - `coach`  delegates to `User.disableCoach` AND the operator-level
+ *              assistant master flag (`getAssistantFlags().coach`). Both
+ *              must agree, matching the two-layer model the client gates
+ *              already enforce. Also AND-ed with operator availability.
+ *   - every other module resolves its user-layer state purely from
+ *              `modulePreferencesJson` as a DISABLED allowlist (absent /
+ *              empty / `true` ⇒ on; an explicit `false` ⇒ off). Default-on.
+ *
+ * Fail-closed posture: the resolver only ever DISABLES a module when it
+ * sees an explicit, well-typed `false` (or, for delegated modules, the
+ * delegated source returning disabled). A malformed blob, a missing
+ * column, an unknown key — none of these can silently disable a module
+ * (default-on), and none can enable a delegated one against its real
+ * source. A crafted `{ "weight": false }` blob is inert because `weight`
+ * is a core domain, not a `ModuleKey`.
+ *
+ * Reads are memoised per-request (the assistant-flags pattern) so a
+ * single request that gates several modules hits the row once.
