Platform-wide hardening: the failure classes found live this week hunted down
across every integration.
Fitbit carried the same tombstone wedge fixed for Google — probe now matches
soft-deleted rows and the update resurrects them; the comment describing a
partial unique index that never existed is corrected. Sleep segment ids are
stable across re-scoring for Withings (session+segment-start), WHOOP/Polar
(one segment per stage, no positional index) and Oura (run-start keyed), each
with a session-scoped sweep that soft-deletes rows a re-score orphaned — so
legacy and affected nights heal as they are re-read.
One platform rule for deleted rows: source-owned readings resurrect on
re-import (Withings, WHOOP, Oura, Polar, Nightscout, mood webhook, CSV
re-imports, Apple stats day-totals); Apple sample-grain deletions stick per
the paired-client contract, and the mood bulk route's tombstone match is now
a true no-op reported as duplicate. Import counts reconcile against actual
createMany counts.
Google lifecycle: a dead token registers on the cycle's hard-fail ledger, so
an expired connection parks instead of stamping success hourly; backfill and
sleep-repair markers stamp only after a clean pass (pg-boss retries are now
real); failed measurement writes hold the watermark; no-op updates are
skipped; mapping.md tells the current truth.
Scale: doctor-report reads only consumed columns and enabled sections;
exports and backups keyset-paginate; achievements tally via SQL buckets;
series charts day-bucket dense kinds beyond 90 days; BP pairing is a linear
two-pointer; distinct-type scans run server-side; the graded-series cold
fallback is bounded; the fitbit defer tracker loops instead of spreading.
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 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.
The entries URL carries the access token as ?token=<secret>; a SafeFetchError
embeds the full target URL in its message, and the sync feeds err.message into
recordSyncFailure, which the status endpoint returns as lastError. Strip token
and api-secret query values to =REDACTED before the message reaches the ledger,
so the secret can never surface in the status response.
Route the sync write through mapSgvEntryToMeasurement so the
entry-to-measurement shape has one source of truth instead of an
inline copy plus an unused parallel mapper that could drift.
Pull continuous glucose readings from a self-hosted Nightscout instance
and store them as immutable BLOOD_GLUCOSE mg/dL measurements
(source=NIGHTSCOUT), giving the glucose panel real CGM density.
- client over safeFetch: public-host pin by default, relaxed only on the
per-user private-network opt-in; redirect pinned manual + timeout
- credentials encrypted at rest on User; URL is the connect marker
- sync maps SGV entries first-write-wins on (userId,type,source,externalId)
- connect/disconnect/status routes: apiHandler + requireAuth + rate limit;
connect validates by a live test fetch with clear errors
- hourly poll-cohort job registered in the all-queues registry
- settings card with URL, token, and the private-network toggle
- i18n across all six locales
