 ## [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.
+
+## [1.31.8] — 2026-07-21
+
+- **MCP search cursors keep lab results stable across pages.** Distinct analyte
+  names are ordered before offset pagination, preventing repeated or skipped
+  lab entries when a client follows `nextCursor`.
+- **Opening the medication wizard no longer risks clearing entered fields.**
+  The one-shot URL flag is removed without starting a second page navigation,
+  so slower browsers keep the active wizard instance and its form state.
+
+No migrations. No breaking changes.
+
+## [1.31.7] — 2026-07-20
+
+- **Current OpenAI reasoning models use their supported request contract.**
+  Official GPT-5, o1, o3, and o4 models receive `max_completion_tokens`
+  without unsupported `temperature` or `seed` fields; compatible custom
+  gateways retain the legacy parameters they advertise.
+- **Apple Health XML cumulative totals no longer add overlapping sources.**
+  Imports aggregate each source/day independently and select the highest
+  source subtotal, while explicit provenance prevents XML estimates or late
+  legacy samples from overwriting authoritative native HealthKit statistics.
+  Existing legacy aggregates can be repaired by re-uploading their archive.
+- **Every currently actionable medication reaches Today.** Equal-time doses no
+  longer collapse to one row, overdue doses win deterministic ties, and weekly
+  or custom intake windows use the scheduling engine's real availability
+  boundary. The shared digest fixes both the web start page and iOS Home.
+
+Migration `0263_apple_health_aggregate_authority`. No breaking changes.
+
+## [1.31.6] — 2026-07-21
+
+- **The hardened runtime image can run database migrations again.** The
+  isolated Prisma CLI now exposes its pinned `dotenv` and `prisma/config`
+  dependencies to the copied production configuration while package managers
+  remain absent from the final image.
+
+No migrations. No breaking changes.
+
+## [1.31.5] — 2026-07-21
+
+- **The production image no longer ships build-time package managers.** pnpm 11
+  verifies the lockfile under explicit build-script policy, npm and Corepack
+  are removed after migrations are prepared, and linked worktrees stay out of
+  local Docker build contexts.
+
+No migrations. No breaking changes.
+
+## [1.31.4] — 2026-07-21
+
+- **Web and background processes now start and recover predictably.** Invalid
+  encryption-key configuration fails before the service accepts traffic,
+  worker-only processes report their real health, connection limits are
+  divided safely across replicas, and provider backfills keep their bounded
+  queues during reconnects.
+- **Published images are reproducible and verified before promotion.** The
+  release pipeline builds one multi-architecture image, validates its digest,
+  startup, migrations, health, and reported version, and only then promotes
+  that exact artifact to production.
+- **CI now uses isolated, deterministic test environments.** Integration tests
+  receive their own database and cryptographic settings before application
+  code loads, worktrees install hooks consistently, and browser tests use the
+  intended application process on every platform.
+- **Concurrent iOS registrations no longer fail intermittently.** Device and
+  APNs notification-channel reconciliation now share one database lock and
+  transaction, so simultaneous first registration remains idempotent.
+
+No migrations. No breaking changes.
+
+## [1.31.3] — 2026-07-20
+
+- **Document summaries now stay in the language you chose.** The same account
+  language is used whether a summary is created in the background or requested
+  from the document sheet. A saved summary remains visible and can be replaced
+  with **Generate again** after you switch languages.
+- **The Coach composer has more room on phones.** The writing field now gets
+  its own line, with document and conversation actions below it and Send on the
+  right. The unreliable browser dictation button and its dead-end permission
+  states are gone.
+
+No migrations. No breaking changes.
+
+## [1.31.2] — 2026-07-20
+
+- **Provider imports now commit identity and progress atomically.** Withings,
+  WHOOP, Oura, Polar, Strava, and Apple Health reconcile external and natural
+  measurement identities under database locks, preserve tombstones, emit
+  arrivals only for genuine inserts, and advance cursors only after durable
+  writes. OAuth refresh-token rotation is serialized per user and provider.
+- **Webhook and import success now means the source data is durable.** moodLog
+  writes before acknowledging delivery, while Withings ECG callbacks enter a
+  durable queue with bounded retry and replay-safe processing. WHOOP backfills
+  commit bounded chunks without advancing failed resource cursors, and legacy
+  mood imports use deterministic, collision-free retry identities. Operational
+  JSON import failures are reported as failures instead of misleading
+  duplicate skips.
+- **Recovery is complete, exact, and owner-safe.** Canonical backups round-trip
+  every supported record class, including encrypted document content,
+  measurement reconciliation identities, and tombstones. Restore rejects
+  account mismatches before writing, validates backup enums at the boundary,
+  processes stable measurement IDs in bounded batches, and preserves recovery
+  integrity across both uploaded and off-host payloads.
+- **Device and mood edits no longer lose related state.** Same-user APNs
+  registrations merge transactionally without crossing account boundaries,
+  refresh-token bindings follow the surviving device, and mood edits preserve
+  rated factors unless the caller explicitly replaces them.
+- **Polar sync follows the current AccessLink collection API.** Collection
+  requests no longer include the obsolete user ID path segment, and current
+  activity, Nightly Recharge, cardio-load, sleep, and SpO2 response shapes are
+  normalized without losing stable measurement identity.
+- **The July dependency bundle is included.** PDF.js 6 now releases its loading
+  task correctly; Canvas 1.0, Radix UI 1.6.2, Tailwind CSS 4.3.3, the Tailwind
+  Prettier plugin 0.8.1, and setup-node 7 are integrated.
+
+No migrations. No breaking changes.
+
+## [1.31.1] — 2026-07-19
+
+- **Arrival events now follow committed inserts across every writer.** Provider
+  re-sync updates stay silent, partial Apple Health imports retain arrivals
+  from earlier committed batches, all newly inserted workouts emit, and sleep
+  refreshes distinguish new stages from updates. Web-only processes now retry
+  their bounded send-only queue connection instead of permanently losing
+  arrival jobs after one transient startup failure.
+- **Reaction and workout generation are single-spend operations.** Durable
+  database claims close worker races and provider-retry gaps, daily token
+  reservations are atomic and reconciled on every terminal path, and both
+  generation and display honor the user's Insights and Workouts module choices
+  plus server-managed consent.
+- **AI context is narrower and more accurate.** Arrival reactions use the
+  record that actually landed, completed sleep uses the reconstructed night
+  rather than one stage segment, user-authored lab fields are fenced as data,
+  workout comparisons use canonical sessions and dates, and every metric and
+  derived-score coach entry carries its exact supported scope.
+- **Dashboard state survives old and partial clients.** Saved comparison range
+  points and newly supported metric widgets are preserved, while Today
+  freshness remains aligned across local-day boundaries, DST, tab focus, and
+  split web/worker deployments.
+
+Three migrations (0260, 0261, 0262). No breaking changes.
+
+## [1.31.0] — "The record that reacts" — 2026-07-19
+
+A milestone release: the record now visibly responds when something lands,
+instead of waiting for a daily rollup to notice.
+
+- **Today shows what just came in.** A completed night's sleep, a workout, a
+  first weigh-in of the day — the home screen now carries a calm "just in"
+  note for a few hours after each one, and at most one written line a day per
+  kind, grounded in your own numbers. Nothing changes if you run without an
+  AI provider: the sentence is the garnish, not the feature — the arrival
+  itself still appears, including on an otherwise-empty record, and an open
+  dashboard refreshes it as soon as the tab becomes visible again. The
+  underlying change that makes this possible without new polling or a flood of
+  background work: every write path that can produce a genuinely new reading
+  now emits a single typed event, day-scoped and de-duplicated, that a mass
+  import or a provider re-sync produces none of — a ten-year import or a
+  month of catch-up sync stays silent, by construction, not by luck.
+- **A finished workout gets its own paragraph.** Opening a recent session now
+  shows a short, grounded read of that one activity — duration, effort,
+  where it sits against your own recent sessions for the sport — with no
+  training advice and no target zones. It is generated once, the first time
+  you open a fresh session, never on re-sync and never for older workouts
+  already in your record.
+- **"Ask why" reaches every read-only card.** Every per-metric status card,
+  every derived-score page, and a finished workout now carries a way straight
+  into the coach, pre-loaded with just that card's own data so the
+  conversation starts already grounded — not with a blank prompt.
+- **The lab-marker card and the offline metric texts speak with the same
+  voice as everything else** — meaning first, in your own language across
+  all six locales, checked by an automated tone pass that now runs on every
+  change to these surfaces so this kind of drift gets caught before it ships
+  again.
+- **The dashboard layout stops discarding a comparison choice on save,** and
+  four clinical widgets stop disappearing from a saved layout — both from a
+  save made by a client that does not know those particular fields yet.
+- **Mood and BMI reach the app's home screen**, and a medication pen can now
+  carry the maker and printed strength that show up in the native pen list.
+- **Every new AI call this release can cause is metered and bounded**: a
+  daily cap per kind, a duplicate-content check that makes a re-post free,
+  and a token reservation that is always reconciled, including on every
+  failure path — the same discipline the rest of the AI surface already
+  holds to.
+
+Two migrations this release (0257, 0259); an additional dashboard-widget
+migration carried over from the prior line. No breaking changes.
+
+## [1.30.35] — 2026-07-19
+
+- **The metric texts you see without an AI provider now speak your
+  language.** They shipped in German and English only; French, Spanish,
+  Italian and Polish fell through to English. These are what nine metric
+  cards render whenever no provider is reachable — no key configured, an
+  outage, a spent budget — so for those readers this text was the app's
+  voice, in the wrong language. Written per language rather than
+  translated: where a sentence could not be formed naturally, that
+  language got its own sentence.
+- **The lab-marker card leads with what a value means**, like every other
+  card already did. It was the last one still instructed to state the
+  number first.
+- **The response length for a metric assessment is set in one place**
+  again, instead of one card carrying its own inline pair.
+- **The fallback texts open on something honest** rather than on an
+  instruction, and the lab-marker card no longer shows the multi-metric
+  overview tip on a single value.
+
+No migrations. No breaking changes.
+
+## [1.30.34] — 2026-07-19
+
+- **Rearranging your dashboard no longer wipes the comparison baseline.**
+  A layout save from a client that does not know about that setting — the
+  app never sends it — silently reset it to "none". Every field of the
+  layout now has to declare whether an absent value means "clear it" or
+  "leave it alone", so the next field added cannot repeat this.
+- **Four clinical widgets stopped disappearing from a saved layout.**
+  Pain, grip strength, waist and waist-to-height were dropped by the save
+  as unknown, so a placed widget was lost every time.
+- **Mood and BMI reach the app's home screen.** Both existed in the
+  record but were absent from the summary the app reads, so those two
+  tiles could not be shown while every other one worked.
+- **A pen carries its manufacturer and printed strength.** Without them,
+  containers entered on the web could not be shown in the app's pen list.
+- **Destructive controls ask first.** Signing every other device out,
+  revoking a session, and revoking a trusted device fired on a single
+  tap. A sweep found two more with neither a confirmation nor an undo: a
+  Coach reminder and a travel entry. Deleting a document still does not
+  ask — it can be undone, which covers the mis-tap.
+- **Delete confirmations stop overclaiming.** Four of them promised the
+  deletion could not be undone while the same screen offered an undo.
+  Warnings that are wrong make the ones that are right easier to ignore.
+- **The sleep-debt figure is described correctly again.** The calculation
+  changed to a running balance that credits surplus in v1.19.0; the label
+  still said "cumulative shortfall". The wrong description had spread to
+  the Coach, which was reasoning about the number on the old definition,
+  and to the published API description.
+- **The glucose reference band can be chosen on the web.** The setting
+  already worked and already fed the Coach — nothing on the web set it.
+  It selects a reference range; it is not a diagnosis and is never
+  inferred from a reading.
+
+One migration (0256), additive. No breaking changes.

+statistics, so the importer does not sum different devices or apps

+## Aggregate authority and recovery
+
+Native HealthKit daily statistics submitted by the iOS batch endpoint
+are canonical and carry `HEALTHKIT_STATISTICS` provenance. XML
+source-maximum estimates carry `EXPORT_XML_SOURCE_MAX`. Both use the
+same serialized reconciler with this ordering:
+
+`LEGACY_UNKNOWN < EXPORT_XML_SOURCE_MAX < HEALTHKIT_STATISTICS`
+
+A later XML import cannot overwrite native statistics. Native
+statistics repair an XML estimate or legacy row in either arrival
+order, and every material reconciled update or resurrection increments
+`syncVersion`. Existing Apple Health `stats:*` rows are migrated to
+`LEGACY_UNKNOWN`; they are never guessed or heuristically promoted.
+To recover an already-corrupted legacy total, the user must re-upload
+the original archive under parser revision 2 or sync native HealthKit
+statistics. Without either input, the correct per-source total cannot
+be reconstructed from the stored aggregate.

+ * v1.31.0 — Today reacts in place.
+ *
+ * The milestone's actual moment: new data lands, and the ALREADY-OPEN
+ * dashboard starts reading differently on the cadence it already runs. No new
+ * poll, no push, no socket — a state change, not a notification.
+ *
+ * The spec drives that end-to-end against the real read path:
+ *
+ *   1. load the dashboard with nothing fresh — no chip, day is provisional;
+ *   2. land last night's sleep through the REAL batch endpoint, and the
+ *      arrival marker the spine's worker would have written;
+ *   3. surface the tab's real visibility-change signal — the browser event
+ *      TanStack Query's focus manager consumes for
+ *      `refetchOnWindowFocus: "always"` (alongside the 120 s foreground poll);
+ *      using that existing trigger keeps the test inside the real cadence
+ *      while staying well under the poll interval;
+ *   4. assert the chip appeared and the phase flipped — in place, no reload.
+ *
+ * The marker is seeded directly rather than waited for from pg-boss: whether
+ * the queue drains inside the e2e web server is the SPINE's contract and has
+ * its own tests. What this spec owns is everything downstream of a marker
+ * existing — the read path, the DTO, and the surface.
+ *
+ * Assertions anchor on `data-slot` / `data-phase`, never on visible text:
+ * responsive `sm:hidden` classes have broken `getByText` in this repo before.

- * @fileoverview ESLint rule — client-side `/api/...` calls must route
- * through the typed `apiFetch` wrapper.
+ * @fileoverview ESLint rule — client-side requests must route through the
+ * typed API-fetch entry points.
  *
- * `src/lib/api/api-fetch.ts` owns the `.ok` check, the
- * `{ data, error, meta? }` envelope unwrap, and the `ApiError` shape
- * (message via `readError`, `status`, error-side `meta`). A raw
- * `fetch("/api/…")` in a component re-implements that contract by hand
- * — the exact drift this wrapper retired — so this rule flags it at
- * authoring time and in CI.
+ * 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.
  *

- * `node_modules` tree nor the `@/` path alias, so the previous
- * `dotenv/config` + `@/lib/db` import chain died with "Cannot find
- * module" inside the container. This script therefore depends on
- * exactly ONE package — `pg` — and reads `DATABASE_URL` straight from
- * the environment (no dotenv). Inside the production image `pg` resolves
- * via `NODE_PATH=/opt/pg-boss/node_modules` (Dockerfile installs
- * `pg@8.x` there); in a repo checkout it resolves from the project
- * `node_modules`. The `pnpm dlx` invocation below supplies `tsx` (the
- * standalone image strips it) and pins `pg` for any environment where
- * neither resolution path exists.
+ * The production standalone image does not expose the project package
+ * manager. It provides a pinned `healthlog-tsx` maintenance launcher, while
+ * `pg` resolves from the standalone runtime tree. In a repo checkout, run the
+ * same script through `pnpm dlx --package pg --package tsx tsx ...`.

+/**
+ * Copy-matches-behaviour guard.
+ *
+ * Three classes of copy that drifted away from the code they describe, each
+ * pinned here so the pair fails loudly if either half moves again:
+ *
+ *   1. DELETE CONFIRMATIONS. A confirmation is the moment a user weighs the
+ *      consequence. Four dialogs promised permanence on surfaces that render
+ *      an Undo affordance (measurements bulk, mood bulk, labs, illness) — a
+ *      cautious user declines a safe delete, and the warning loses weight
+ *      where it is true. This test pins both directions: undo-able surfaces
+ *      must offer the undo sentence and must NOT claim finality; the
+ *      genuinely permanent ones must keep their warning.
+ *
+ *   2. SLEEP DEBT. v1.19.0 replaced the summed shortfall with a running
+ *      balance that credits surplus sleep. The labels still described the old
+ *      arithmetic, so the word contradicted the number for anyone who caught
+ *      up after a short night.
+ *
+ *   3. GLUCOSE REFERENCE BAND. The declared diabetes opt-in has a server
+ *      preference and a route; the copy for its web control must exist in
+ *      every locale, since a missing key silently degrades to the raw key on
+ *      a surface that makes a clinical-adjacent claim.
+ *
+ * Reversibility evidence for the undo-able set:
+ *   - measurements: `POST /api/measurements/restore`, undo toast in
+ *     `src/components/measurements/measurement-list.tsx`
+ *   - mood:         `POST /api/mood-entries/restore`, undo toast in
+ *     `src/components/mood/mood-list.tsx`
+ *   - labs:         `POST /api/labs/restore`, undo toast in
+ *     `src/components/labs/lab-history-list.tsx`
+ *   - illness:      `POST /api/illness/episodes/[id]/restore`, undo toast in
+ *     `src/components/illness/episode-menu.tsx`

  *
- * The riskiest endpoint in the backup family. Mirroring the v1.4.14 wipe
- * scope (`DELETE /api/admin/data`), the restore replaces the **target
- * user's** personal data with the contents of the snapshot:
+ * After owner and schema validation, one transaction replaces every
+ * serialized owner-scoped class: measurements, medication history, mood and
+ * rated factors, cycle data, labs/biomarkers, illness history, allergies,
+ * family history, workout summaries, and inbound documents. Document content
+ * and summary ciphertext are decoded from base64 and persisted verbatim.
  *
- *   1. Decrypt + parse the `DataBackup.data` blob.
- *   2. In a single Prisma transaction:
- *      a. Delete the user's measurements, medications (cascades to
- *         schedules + intake events + telegram messages +
- *         reminder-phase configs), mood entries, notification channels,
- *         push subscriptions, telegram scheduled deletions.
- *      b. Re-create measurements, medications + schedules, intake
- *         events, mood entries from the payload.
- *   3. Outside the transaction, write `admin.backups.restore` to the
- *      AuditLog so the trail outlives the operation. Audit rows are
- *      intentionally NOT touched by the restore (same contract as the
- *      wipe).
- *
- * Triple-confirm: the request body must carry `confirm: "RESTORE"`.
- * The client also gates the form on a typed-string match so an
- * accidental click cannot fire this.
- *
- * Idempotency: wrapped in `withIdempotency()` so retries with the same
- * `Idempotency-Key` replay the original outcome instead of double-
- * restoring (unlikely in practice — the second run would be a no-op
- * because the user data already matches the backup — but this still
- * prevents two parallel admin clicks from racing through).
- *
- * Phase B1 / criterion 3 of the v1.4.15 backup-completeness work.
+ * Metadata-only portable document exports are rejected before mutation; the
+ * importer never fabricates content. Audit rows remain outside the wipe, and
+ * cache invalidation runs only after the complete restore transaction.

+ * Three contracts are pinned here, in order of how much they would cost if

+ *
+ *  1. SNAPSHOT-ONCE. The workout evidence is read and pinned on the FIRST turn
+ *     only. If a later turn rebuilt it, per-turn work would grow with the
+ *     conversation — which is exactly the cost the snapshot-once design
+ *     removed. The multi-turn case asserts the workout read fires exactly once
+ *     across a conversation that keeps sending the id.
+ *  2. TENANCY. The row is narrowed by `{ id, userId }`. Another user's workout
+ *     id therefore resolves to nothing, and the conversation proceeds on the
+ *     standard snapshot rather than leaking a foreign session's numbers.
+ *  3. The evidence rides INSIDE the fenced snapshot payload, so it inherits the
+ *     data/instruction contract the fence states.
+ *
+ * Mock scaffold mirrors route-snapshot-once.test.ts so `../route` imports

+ *    diluted by a second scope).

+ * 1. HYDRATION. The hero is deliberately NOT mount-gated — it paints from the
+ *    server-dehydrated digest on the SSR pass because it is the LCP element
+ *    (v1.30.9). So anything inside it that differs between the server and the
+ *    browser is a React #418 mismatch. A wall-clock time is exactly that: the
+ *    server's locale and timezone are not the reader's. The chip therefore
+ *    renders its SLOT on both passes and fills the time in only after mount.
+ *    These tests render through `renderToStaticMarkup`, which takes the SERVER
+ *    snapshot of `useSyncExternalStore` — i.e. precisely the pass that must
+ *    carry no formatted time.
+ *
+ * 2. NO LAYOUT SHIFT. The reaction line REPLACES the lead; it is never a second
+ *    paragraph. The hero stays one lead line tall, so nothing below it moves
+ *    when the line arrives on a poll.

- * verdict.
+ * Mounts only when the workout payload carries a paragraph — the page composes
+ * `{aiInsight ? <WorkoutInsightCard insight={aiInsight}/> : null}`, and `null`
+ * is the common case rather than an error state: a paragraph exists only for a
+ * session that LANDED while the feature was live, ran over ten minutes, fell
+ * under the day's cap, and found a provider. Every workout that predates the
+ * feature, every re-synced one, and every one on a provider-less install
+ * renders nothing here, permanently. Opening this page never generates one.
+ *
+ * Non-diagnostic by construction: a descriptive paragraph, device-attributed,
+ * compared only to the user's own history, never a verdict and never a training
+ * prescription (the contract lives in `@/lib/ai/prompts/workout-insight`).
+ *
+ * The paragraph renders as React TEXT CHILDREN, deliberately. There is no
+ * markdown library in this project and adding one is a security decision, not a
+ * formatting one — model output rendered as markup is an XSS surface.

+ * The flag answers exactly the question this page answers — "which range is my
+ * reading judged against" — and the page already owns the four glucose target
+ * rows. Putting it anywhere else would split one concept across two surfaces.
+ * The card sits ABOVE the per-metric editor because the two controls are
+ * ordered: this one picks the default band, a per-metric override below then
+ * beats it (`src/lib/targets/glucose-targets.ts`).
+ *
+ * WHAT IT DOES NOT DO
+ * -------------------
+ * The flag is a display preference, never a diagnosis, and is never inferred
+ * from a reading. It selects the band the glucose surfaces and the Coach's
+ * reference grounding read; the app takes no clinical action on it. The copy
+ * says so at the point of the switch rather than in a help page.
+ *
+ * Note: `GET /api/user/thresholds` (the editor below) reports the general
+ * bands regardless of this flag — the flag resolves in the targets pipeline
+ * (`src/lib/targets/build-response.ts`), which is why the mutation invalidates
+ * `insightsTargets()` rather than `userThresholds()`.

- * The test only exercises the `getPoolMax()` env-resolver. Constructing

- * make this an integration test instead of a unit test — the helper
- * isolation is intentional.

- * Walks every `.ts` / `.tsx` file in `src/components/charts` and
- * `src/app/page.tsx` (the dashboard + chart files we own in this wave)
- * and fails if a literal `queryKey: [...]` slipped past the factory.
- * Acts as a lint-style enforcement check in the absence of a custom
- * ESLint rule — keeps the CI gate cheap and the failure message
- * pointed at the exact file the contributor needs to fix.
- *
- * The audit (`.planning/round-v1439-arch-qa-frontend.md` §H1) found
- * 154 bare queryKey sites at v1.4.39.3. We intentionally scope this
- * guard tight to the dashboard + chart files this wave touched so a
- * future wave can extend the directory list as it migrates the
- * remaining sites — opt-in expansion beats a giant red CI on
- * landing.
+ * Components and hooks are client-facing by convention. App and lib modules
+ * join the guarded surface when they declare `"use client"`. Tests and the
+ * factory definition directory are excluded because they intentionally build
+ * literal fixtures and key tuples.

+/**
+ * Per-workout evidence block for a Coach conversation launched from a
+ * workout ("Ask why" on the workout-detail page, or `/coach?workout=<id>`).
+ *
+ * ── Why this block is NOT fenced ─────────────────────────────────────
+ *
+ * The stored-document path (`?doc=`) routes every turn through the hardened
+ * fenced endpoint because document text is third-party prose transcribed out
+ * of a PDF — an injection surface by construction. A workout row is not:
+ * it is the user's own structured sensor record. This block therefore rides
+ * the normal Coach prompt as one additional snapshot section.
+ *
+ * That reasoning only holds if the projection really is numbers-only, so the
+ * closure is enforced here rather than assumed:
+ *
+ *   - Every emitted leaf is a NUMBER, a BOOLEAN, or a token drawn from a
+ *     closed server-side vocabulary. `assertNumbersOnly()` walks the built
+ *     object and throws on anything else, so a future field that smuggles a
+ *     string in fails loudly at build time instead of silently reaching a
+ *     prompt.
+ *   - `sportType` is a TEXT column at the DB layer (see `Workout.sport_type`
+ *     in `prisma/schema.prisma`). The write path constrains it to
+ *     `workoutSportTypeEnum`, but the backup-restore path accepts
+ *     `z.string().min(1)`, so a restored row can carry arbitrary text. It is
+ *     therefore re-asserted against the closed enum here and folded to
+ *     `"other"` on a miss — the same whitelist posture the raw-SQL splices
+ *     use.
+ *   - `metadata` is EXCLUDED wholesale. It carries device bundle ids and
+ *     HKWorkoutEvent markers — free text with no numeric value to the
+ *     narrative. Only the WHOOP zone durations are read out of it, and only
+ *     through the narrow numeric Zod slice `parseWhoopZoneDurations()`.
+ *   - `externalId` / `externalSourceVersion` are EXCLUDED — opaque
+ *     device-assigned strings.
+ *   - Route GEOMETRY is EXCLUDED. The per-point coordinate trace is the
+ *     user's location history; the climb figure the narrative needs is
+ *     already the numeric `elevationM` column.
+ *
+ * The conversation-level tenancy narrow (`{ id, userId }`) lives in the
+ * explicit-dependency workout evidence builder; this module never widens it.

+ *   - Fire-and-forget and fully try/caught. An emit failure can NEVER fail the

- * `findMany`. On a CGM + per-sample-HR account that is a six-figure row set
- * materialised by a single query — the v1.28.2x incident class. This helper
- * keeps the output row set (and its `measuredAt desc` order) identical while
- * bounding each database round-trip to `MEASUREMENT_EXPORT_PAGE_SIZE` rows:
- * the driver never buffers one giant result, and the event loop yields
- * between chunks.
- *
- * Ordering: `measuredAt desc, id desc`. The exports always sorted
- * `measuredAt desc`; the `id` tie-breaker makes the keyset cursor total (two
- * rows can share a timestamp) — for equal-timestamp rows the previous order
- * was unspecified heap order, so pinning it is not a behaviour change any
- * consumer could have relied on.
- *
- * The `select` MUST include `id` (the cursor key); the generic constraint
- * enforces it at compile time.
+ * Pages are ordered by `measuredAt desc, id desc`. The `id` tie-breaker makes
+ * the keyset cursor total when measurements share a timestamp. Consumers own
+ * one page at a time; advancing the iterator releases the previous page before

+/**
+ * Structural guard: the data-arrival worker cannot reach a provider.
+ *
+ * The spine's central cost claim is that it spends nothing. That claim is only
+ * as good as the worker's module graph: the moment anything reachable from
+ * `data-arrival.ts` imports a provider client, a mass ingest becomes a mass of
+ * provider calls, and no amount of runtime gating in the handler would show up
+ * in review as the thing that broke it.
+ *
+ * So the guard is structural, not behavioural. It BFS-walks the static import
+ * graph from the worker and asserts no provider module is reachable — the shape
+ * of `documents/__tests__/fenced-chat-module-graph.test.ts`.
+ *
+ * Two deliberate design points:
+ *
+ *   - The forbidden set is GLOBBED, not hand-listed, for the provider clients.
+ *     A hand-written array silently stops covering a `gemini-client.ts` the day
+ *     someone adds one; a glob covers it on arrival.
+ *   - There is a positive control. A graph walk that silently resolves to
+ *     nothing (a moved file, a changed alias, a typo in the entry path) would
+ *     pass every negative assertion vacuously. The control asserts the walk
+ *     DOES reach the modules the worker genuinely uses, so an empty graph fails
+ *     loudly instead of reporting success.
+ *
+ * Known limit, stated because it bounds what this proves: `IMPORT_RE` sees only
+ * static import specifiers. A dynamic `await import(...)` built from a variable
+ * is invisible to it. That is acceptable here — the ban is on a static import,
+ * and a dynamic provider import in a worker would be a far louder thing to
+ * write — but it is not a proof, it is a tripwire.

+/**
+ * The `data-arrival` worker — the consumer end of the arrival spine.
+ *
+ * It runs once per SALIENT arrival (the seam classifier has already dropped
+ * every backfill), claims the day's reaction marker, and fans out to the
+ * deterministic reaction surfaces.
+ *
+ * Two properties are load-bearing and must survive every future edit:
+ *
+ * 1. **No provider import, structurally.** This module — and everything
+ *    reachable from it — imports no AI client and no provider resolver. The
+ *    spine cannot spend a token by construction; the only AI it can cause is
+ *    through explicitly budget-gated sub-queues that it merely ENQUEUES. A
+ *    module-graph test (`__tests__/data-arrival-provider-isolation.test.ts`)
+ *    fails if a provider module ever becomes reachable from here.
+ *
+ * 2. **A refusal is `skipped`, never `failed`.** Every business refusal — an
+ *    unknown kind, an equal/older marker, or a later slice's exhausted cap —
+ *    returns a status. It does NOT throw. This is not a stylistic
+ *    choice: pg-boss retries a failed job, and retrying against a ceiling that
+ *    does not move until the local day rolls over is an unbounded loop. Only a
+ *    genuine transient fault (pool exhaustion, a dropped connection) is allowed
+ *    to escape and earn its two backed-off retries.
+ *
+ * The marker is established FIRST, before any fan-out. A strictly newer
+ * same-day arrival advances it under a row lock and invalidates stale line
+ * ownership first. This ordering bounds downstream failures and prevents old
+ * generation workers from publishing against a replacement.

+/**
+ * The `reaction-line-generate` worker — the day's single sentence about what
+ * just landed.
+ *
+ * This is the ONE provider call the arrival spine can cause, and the whole
+ * design of the surface is arranged so that call is bounded before it is made:
+ *
+ *   - The THROTTLE is a durable unique row plus a provider-attempt timestamp.
+ *     The worker conditionally owns a lease, then writes
+ *     `generationProviderInvokedAt` immediately before egress. A crash,
+ *     timeout, racing spine job, retry, or hand-sent job therefore cannot
+ *     produce a second provider call for the same kind and local day.
+ *   - The SPEND reservation and its marker linkage commit in one PostgreSQL
+ *     transaction. A pre-provider retry reuses that reservation. Reported
+ *     usage is reconciled before ciphertext commits; unknown usage retains the
+ *     conservative reservation.
+ *   - The FLOOR is complete without any of this. No provider, no consent, an
+ *     exhausted budget, a refused output, a dead network — every one of them
+ *     leaves the row line-less, and a line-less row still drives the "just in"
+ *     chip and the provisional→final flip. The reaction is a state change; the
+ *     sentence is garnish. `reaction-line-degradation.test.ts` holds that line.
+ *
+ * The prompt starts with the exact owned row referenced by the arrival marker
+ * (or its exact occurrence timestamp), projected to bounded numeric fields.
+ * The deterministic digest adds only the same computed context rendered next
+ * to the reaction.

+ * The per-workout Activity Insight worker.
+ *
+ * Dispatched by the data-arrival spine when a workout genuinely LANDS. There is
+ * no other trigger and there is deliberately no regenerate button: a per-workout
+ * provider button is a saturation surface, and a read path that could generate
+ * would turn opening the workout list on a fresh install into a bill.
+ *
+ * The consequence is worth stating because it looks like a bug and is not: every
+ * workout that predates this feature, and every workout re-synced from a
+ * provider backfill, renders NO card, forever. That is the design. The spine's
+ * recency classifier drops historical samples before anything is enqueued, the
+ * upsert seams only emit for rows they actually created, and nothing on the read
+ * side ever writes here.
+ *
+ * Five gates stand in front of the provider, in ascending cost order, and each
+ * is a claim on its own rather than a layer of one claim:
+ *
+ *   1. modules   — `workouts` AND `insights` on
+ *   2. duration  — at least ten minutes of session
+ *   3. daily cap — at most four paragraphs generated today
+ *   4. inputHash — the evidence is unchanged since the last paragraph
+ *   5. budget    — the token ledger, inside `runStatusCompletion`
+ *
+ * Gate 3 and gate 4 both independently stop a device double-post, which is why
+ * they are both here: the singleton queue key that would normally collapse a
+ * burst is best-effort, and a lost singleton race is an ordinary event.
+ *
+ * Every business refusal RETURNS a status. It does not throw. pg-boss retries a
+ * failed job, and retrying against a daily cap that does not move until midnight

+/**
+ * WHOOP sync core — token refresh (rotating refresh token), shared
+ * Measurement upsert/rollup-fold helpers, cursors, and sync status handling.
+ *
+ * Mirrors `src/lib/withings/sync.ts`:
+ *   - `getValidToken` decrypts the stored pair, refreshes at
+ *     `tokenExpiresAt - 5 min`, and persists BOTH rotated tokens (WHOOP
+ *     invalidates the prior access AND refresh token on every refresh — the
+ *     same discipline Withings uses for its rotating refresh token). A
+ *     provider/user advisory lock serializes refresh, and token state is
+ *     re-read inside the transaction before the one-time token is spent.
+ *   - Each per-resource sync (`sync-recovery` / `sync-sleep` / `sync-cycle` /
+ *     `sync-workout`) upserts into `Measurement` / `Workout` keyed on
+ *     `(userId, type, source = WHOOP, externalId)` so a re-post (WHOOP
+ *     re-scores recovery/sleep after the fact) overwrites in place rather than
+ *     minting a duplicate. After the upserts the rollup tier is re-folded
+ *     (`recomputeBucketsForMeasurement`) and the status-insight caches are
+ *     invalidated, identical to the Withings tail.
+ *
+ * The incremental window starts from `lastSyncedAt - overlap`. WHOOP re-scores
+ * recovery/sleep hours after the night, so the overlap must comfortably cover
+ * the re-score lag — `WHOOP_RECOVERY_SLEEP_OVERLAP_MS` is 7 days, now shared by
+ * workout ingest too (a phone that syncs to the WHOOP cloud well after a
+ * workout would otherwise fall outside a narrow window and never land);
+ * `WHOOP_DEFAULT_OVERLAP_MS` stays the narrow fallback for other resources.

+ * WHOOP sync orchestrator.
  *
- * Mirrors `src/lib/withings/sync.ts`:
- *   - `getValidToken` decrypts the stored pair, refreshes at
- *     `tokenExpiresAt - 5 min`, and persists BOTH rotated tokens (WHOOP
- *     invalidates the prior access AND refresh token on every refresh — the

- *     is a compare-and-swap on the stored ciphertext so two overlapping syncs
- *     cannot park the connection at reauth (see `persistRotatedToken`).
- *   - Each per-resource sync (`sync-recovery` / `sync-sleep` / `sync-cycle` /
- *     `sync-workout`) upserts into `Measurement` / `Workout` keyed on
- *     `(userId, type, source = WHOOP, externalId)` so a re-post (WHOOP
- *     re-scores recovery/sleep after the fact) overwrites in place rather than
- *     minting a duplicate. After the upserts the rollup tier is re-folded
- *     (`recomputeBucketsForMeasurement`) and the status-insight caches are
- *     invalidated, identical to the Withings tail.
- *
- * The incremental window starts from `lastSyncedAt - overlap`. WHOOP re-scores
- * recovery/sleep hours after the night, so the overlap must comfortably cover
- * the re-score lag — `WHOOP_RECOVERY_SLEEP_OVERLAP_MS` is 7 days, now shared by
- * workout ingest too (a phone that syncs to the WHOOP cloud well after a
- * workout would otherwise fall outside a narrow window and never land);
- * `WHOOP_DEFAULT_OVERLAP_MS` stays the narrow fallback for other resources.
+ * Shared token, cursor, upsert, status, and failure helpers live in
+ * `sync-core.ts`. Resource leaves depend only on that core; this parent owns
+ * the static leaf graph and the full per-user sequencing policy.

+ * The deterministic evidence block behind the per-workout Activity Insight.
+ *
+ * Everything the model is ever told about a session is built here, and the
+ * shape of this module is the security boundary of the whole feature: it is a
+ * NUMBERS-ONLY projection over closed fields.
+ *
+ * What is excluded, and why each one matters:
+ *
+ *   - `metadata` — a JSON blob of device bundle ids, HKWorkoutEvent markers and
+ *     per-vendor extras. Never passed in at all; the only thing taken from it
+ *     anywhere on this path is the numeric WHOOP zone-duration array, and that
+ *     goes through `parseWhoopZoneDurations` before it gets near here.
+ *   - `externalId` — a vendor-supplied opaque string. Never selected.
+ *   - route geometry — consumed to derive ONE number (metres climbed) and then
+ *     dropped. It is location history, not a figure, and it may not ride a
+ *     prompt.
+ *   - `sportType` — a TEXT column. The API write path constrains it to
+ *     `workoutSportTypeEnum`, but the BACKUP RESTORE path accepts
+ *     `z.string().min(1)`, so a restored row can carry arbitrary
+ *     attacker-chosen text. It is therefore re-asserted against the enum HERE,
+ *     at projection time, and anything unrecognised folds to `"other"`. The
+ *     enum is imported from the schema module rather than copied, because a
+ *     hand-copied vocabulary drifts.
+ *
+ * And the claim is enforced by `assertNumericLeaves`, not by this comment: the
+ * projection is walked before it is returned and ANY non-numeric leaf at any
+ * depth throws. A future field that quietly admits a string fails loudly at the
+ * seam instead of arriving in a prompt.
+ *
+ * Determinism is the second contract. The same session always projects to the
+ * same numbers, which is what makes the input hash a real no-op gate: a WHOOP
+ * re-sync or an iOS `stats:` overwrite that changes nothing the paragraph
+ * narrates hashes identically and never reaches a provider.

+ * The pure half of the Activity Insight gate stack.
+ *
+ * Five gates stand between a workout landing and a provider call, and they run
+ * in this order for a reason — each one is cheaper than the one after it, so
+ * the common refusals cost nothing:
+ *
+ *   1. modules  — `workouts` AND `insights` both on (one cached map lookup)
+ *   2. duration — at least `MIN_DURATION_SEC` (a field already in hand)
+ *   3. daily cap — at most `MAX_INSIGHTS_PER_DAY` generated today (one COUNT)
+ *   4. input hash — the evidence is unchanged since the last paragraph (one
+ *      indexed read, no provider resolution)
+ *   5. budget — the token ledger's reserve/reconcile, inside
+ *      `runStatusCompletion`
+ *
+ * Gates 2 and 4 are pure and live here so each can be tested on its own. The
+ * other three need the database and live in the worker beside their query.
+ *
+ * Every one of them is a SEPARATE claim. The daily cap does not depend on the
+ * hash holding, and the hash does not depend on the singleton queue key
+ * holding: a device that double-posts the same session must be stopped by the
+ * unique row and by the hash independently, because a queue key is a
+ * best-effort de-duplication and a lost singleton race is a normal event.

+/**
+ * The `WorkoutInsight` row's structural claims, against real Postgres.
+ *
+ * Unit mocks cannot prove any of this, and each one is load-bearing:
+ *
+ *   - **One paragraph per workout** is a unique INDEX. A mocked `upsert` will
+ *     happily accept a second row for the same workout; the database is what
+ *     actually refuses, and it is the half of the double-post defence that
+ *     holds when the singleton queue key does not.
+ *   - **The cascade** is an FK constraint. Workout deletes are HARD deletes, so
+ *     a paragraph that outlived its workout would be an orphaned description of
+ *     a session the user believes they erased. That is a data-retention claim,
+ *     not a tidiness one, and only the database enforces it.
+ *   - **The daily-cap count** reads an index over `(user_id, generated_at)`.
+ *     Whether the window actually selects the right rows is a SQL fact.
+ *
+ * Every test writes through Prisma the way the worker does, so a schema change
+ * that dropped a constraint fails here rather than in production.
