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.
Polar read three collections off the wire and dropped several useful signals
at the mapper. Close the gaps, keeping every value server-authoritative and
canonical-unit:
- Sleep now follows the END-instant convention the canonical night-grouper
depends on. mapSleep reconstructs an ordered, contiguous CORE/DEEP/REM
timeline from the parsed sleep_start_time / sleep_end_time, stamping each
segment at its own end instant with an indexed externalId, plus an IN_BED
envelope and the score at the sleep end. This restores the hypnogram (the
stages no longer collapse onto one midnight-UTC instant) and fixes wake-day
mis-attribution for negative-UTC users. Records without a usable window fall
back to the prior midnight anchor. Synthetic ordering is flagged
reconstructed.
- ans_charge maps to ANS_CHARGE (through-as-is; a baseline-relative deviation
that can run negative).
- distance_from_steps maps to WALKING_RUNNING_DISTANCE (metres), filling the
Polar distance-ladder slot that previously had no producer.
- New fetchers + mappers for Training Load Pro (cardio_load -> CARDIO_LOAD)
and the Elixir SpO2 collection (-> OXYGEN_SATURATION), with Polar added to
the SpO2 source ladder below the established straps.
No strap/profile weight is fetched; egress stays on safeFetch.
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 a Polar account over AccessLink v3: an authorization-code OAuth
flow (shared app from POLAR_CLIENT_ID / POLAR_CLIENT_SECRET) backed by a
stateless HMAC-signed state token doubling as an httpOnly cookie for CSRF.
The callback verifies the signature, expiry, provider binding, and the
byte-exact cookie match, then encrypts the access token plus member id onto
the user row.
An hourly poll-cohort job maps Nightly Recharge recovery, sleep stages,
and daily activity to canonical measurements tagged source POLAR, idempotent
on (userId, type, source, externalId). The recovery band feeds RECOVERY_SCORE
through the canonical ladder, which now ranks native readiness above the
computed proxy. Settings gains a connect / disconnect card. Tokens are never
logged or returned; every egress goes through safeFetch.
