Fitbit, WHOOP, and Oura all issue one-time-use refresh tokens. The token
persistence did an unguarded read → refresh → write, so two overlapping
syncs for one user both read the same stored refresh token and both POST
it. The provider honours only the first; the loser's refresh comes back 401,
gets classified as reauth, and the connection is parked at `error_reauth`
spuriously even though the peer rotated the token successfully.
Add a shared `persistRotatedToken` helper that writes the rotated pair with
a compare-and-swap on the stored ciphertext (matched verbatim, since AES-GCM
re-encryption of the same plaintext differs byte-for-byte). When the
conditional update touches zero rows a peer already won the race; re-read the
row and reuse the peer's freshly rotated access token instead of erroring.
Wire it into all three providers — Fitbit and WHOOP `getValidToken`
(proactive expiry refresh, keyed by connection id) and Oura `storeOuraTokens`
(reactive 401 refresh, keyed by user id). Both racing callers now end with a
usable token and neither drops the connection.
Oura's daily_resilience collection reports a categorical level — limited,
adequate, solid, strong, exceptional. Encode it ordinally (limited=1 …
exceptional=5) into the numeric measurement value so it fits the existing
model with no new categorical column: add the RESILIENCE measurement type
(migration 0186), fetch and map daily_resilience in the Oura sync, and skip
an unknown or missing level rather than coercing it to zero.
RESILIENCE_LEVELS in the Oura client is the single source of truth for the
encoding. The day-keyed externalId keeps a re-sync idempotent so a re-scored
day overwrites in place. Extend the measurement-type label, unit, range,
category, chart-token, and PR-direction maps; add the metric label across all
six locales.
The daily_cardiovascular_age collection reports a years-unit arterial-age
estimate that maps directly onto the existing VASCULAR_AGE metric, so no
migration is needed. Resilience stays out: it is a categorical level with
no numeric home and would require a new type plus a categorical column.
STRESS_SCORE already has an HRV-derived COMPUTED producer that is not
wired into the source-priority ladder or the weekly graded-series
collapse, so adding a second Oura producer caused nondeterministic
collapse and double-counting. Drop the daily_stress fetch/map/wiring and
leave a note to re-add once STRESS_SCORE is laddered. The vO2_max
mapping, which is correctly ladder-wired, stays intact.
The Oura v2 client fetched sleep, readiness, activity, daily sleep, and
daily SpO2 but skipped the dedicated vO2_max collection and daily_stress.
An Oura user got no VO2max from any path even though the enum, the
cardio-fitness page, fitness-age, norms, and the LOINC code already exist.
Add fetchVo2Max + mapVo2Max (vo2_max -> VO2_MAX, mL/(kg·min)) and
fetchDailyStress + mapDailyStress. Oura exposes no headline stress score,
only minutes in high stress vs high recovery, so derive a bounded 0-100
STRESS_SCORE from the high-stress share of the day's charged time. Both
collections wire into the existing reactive-refresh sync tail; no
migration, no schema change, no iOS-contract impact.
One-shot prettier pass so the new format:check gate starts from a clean
baseline. Formatting only — no behaviour change. Generator-owned and
vendored artifacts stay untouched via .prettierignore.
Deleting a user's stored Oura BYO credentials drops a live connection (a
token minted against the deleted app is orphaned), but the credentials
DELETE route skipped the auditLog + markDisconnected the disconnect route
performs, leaving the integration ledger parked at its last state with no
audit trail. Mirror the disconnect route when a token was present.
Drop two unused classifier type aliases and unexport the internal
invalid-grant helper, and refresh the stale 'full OAuth from env' headers on
the connect route and the env-credentials helper to the v1.17.1 DB-first
framing. Add the missing route tests for the BYO surface this release
touched: credentials GET/PUT/DELETE (422 reject, encrypt-on-write, the
audit/ledger branch) and the callback CSRF / cross-user / nocreds / success
paths.
Widen the Oura sync from a thin slice to the signals the v2 API actually
exposes, all server-authoritative:
- Real measured sleep timeline. mapSleep now reads the per-stage
sleep_phase_5_min hypnogram and emits one timed SLEEP_DURATION row per
contiguous 5-minute run, each stamped at its own end instant from
bedtime_start. The per-night reader reconstructs the true clock-time
timeline (measured, not synthesised) instead of the degraded
all-on-bedtime_end shape. Falls back to the four stage totals when no
hypnogram is present.
- daily_spo2 → OXYGEN_SATURATION and daily_sleep → SLEEP_SCORE, filling
two ladder slots that nothing wrote before.
- daily_readiness temperature_deviation → BODY_TEMPERATURE_DEVIATION, and
the eight readiness contributors are parsed (no longer dropped at the
JSON boundary) for the Insights surface.
- daily_activity equivalent_walking_distance → WALKING_RUNNING_DISTANCE,
so an Oura-only day no longer contributes zero distance.
Every sleep row now carries a record-scoped externalId
(sleep:<record-id>:<tag>) so a nap and the main sleep on one day stay
distinct instead of overwriting each other on a shared day key.
Polar and Oura resolved their OAuth client id/secret from the server
environment only, forcing every user on a deploy to share one app. Both
now read per-user BYO keys first, falling back to the shared env app when
unset, mirroring the WHOOP and Fitbit model.
- Add DB-first-then-env resolvers in src/lib/{polar,oura}/credentials.ts,
encrypting the client id/secret at rest on User.
- Repoint the connect, callback, status routes and the Oura refresh path
to the user-scoped resolver.
- Add /api/{polar,oura}/credentials (GET/PUT/DELETE) with Zod-validated
input and userId narrowed from the session.
- Render an optional 'your OAuth app credentials' form on the Polar and
Oura cards; the status read exposes hasOwnCredentials for the saved
placeholder. Existing env-only deploys keep working unchanged.
- Cover both resolvers (DB hit, env fallback, no creds) and the card form
with unit tests; add the new strings across all six locales.
The mobile settings test asserted three integration pills; Polar, Oura and
Nightscout bring the list to six. Remove the unused Oura and Polar field-map
documentation constants and the unused advanced-indices interface the dead-code
gate flagged.
Polar and Oura response classifiers were byte-identical copies of the
status-driven verdict, the typed API error, and the invalid_grant probe.
Extract classifyHttpStatus, an IntegrationApiError base carrying the vendor
label, and a vendor-scoped isOAuthInvalidGrant into a shared module; Polar
and Oura now re-export under their existing names and types so call sites
and instanceof checks are unchanged.
Collapse the triplicated classifyXFailure mapping (Polar, Oura, Nightscout)
onto one toFailureKind helper. Behaviour is identical: same classifications,
same failure kinds, same error types.
Connect an Oura account over the Cloud v2 API: an authorization-code OAuth
flow (shared app from OURA_CLIENT_ID / OURA_CLIENT_SECRET) on the same signed
state machinery as Polar. Unlike Polar, Oura issues refresh tokens; the sync
refreshes reactively on a 401, rotating and re-encrypting both tokens, and a
403 stays a hard reauth rather than a refresh.
An hourly poll-cohort job maps daily readiness to RECOVERY_SCORE, sleep to
per-stage durations plus efficiency / HRV / resting heart rate / respiratory
rate, and daily activity to steps and active energy — all tagged source OURA,
idempotent on (userId, type, source, externalId). Readiness flows through the
canonical recovery ladder above the computed proxy. Settings gains a connect /
disconnect card. Tokens are never logged or returned; every egress goes
through safeFetch.
