Integration syncs (Fitbit, Oura, Polar, WHOOP, Strava, Nightscout) now
mark the per-user analytics cells stale and sweep the workouts cache at
their sync tails — imported rows used to stay invisible to the cached
dashboard, analytics and workout readers until the TTL lapsed. The WHOOP
per-resource webhook/cron driver and the Polar workouts leg carry the
same call, matching the posture Google Health and the workout batch
route already had.
Illness, cycle and encounter write routes hard-evict the analytics
bucket through the new invalidateUserHealthContext helper: Rest Mode,
the cycle context and the Today-rail appointment feed all read from
cached cells under that bucket, and an interactive write must be true on
the very next read.
A sync failure the classifier bucketed as `transient` had no exit. The park
test read `kind === "persistent"` and the persistent streak anchor was only
ever stamped by a persistent failure, so a streak could run for a thousand
attempts with the persistent counter at zero, the state frozen at
`error_transient`, and no ladder it could climb. `transient` is a hypothesis
about retryability, and the classifier defaults every timeout, 429, 5xx and
unrecognised response to it precisely because the wire cannot tell a reboot
from a permanent break. That default is right for one attempt and wrong for a
thousand: an unbroken streak retried hourly for a full day has refuted it by
experiment. Record it as `persistent` from there, which feeds the park ladder
that already exists — 48 h of unbroken failure end to end before an
integration stops attempting.
The counters could not accumulate anyway. `IntegrationStatus` is keyed
(user, integration) while Withings runs four legs on four crons and WHOOP four
resources on four more, and a success cleared the error, every bucket, the
streak anchor and the state whatever leg had recorded them. The ECG tick at
:41 wiped what the sleep tick recorded at :15 — including a reauth park — so
the strike ladder was reset several times an hour and the card painted a green
"connected · 12 minutes ago" over a data class that had stopped arriving. A
success now clears only what it is entitled to clear.
Two columns carry it: `failing_since_at` dates the streak, `failing_leg` names
its owner. The migration backfills the anchor for rows already in an error
state so a connection broken for weeks escalates on its next attempt rather
than restarting its clock.
Introduce a recorded-marker primitive on the integration ledger so a provider
that records-then-rethrows a sync failure is not recorded a second time at the
poll-cohort boundary, while an unrecorded escape (an Oura or Polar write-path
throw, or any future path) lands on the ledger exactly once, correctly
classified and redacted by the source that owns it. Without the marker a
boundary-blind recorder would double-count the failure streak and could persist
a Nightscout token-bearing URL into the stored error.
Give the poll-cohort factory a required per-provider failure recorder and wire
one for Oura, Polar, Nightscout, and Strava.
Nightscout now counts only freshly inserted readings instead of insert plus
re-confirm (the inflated count fired the reminder trigger every tick), records a
transient failure and skips the success stamp when some rows fail to write, and
emits the measurement-arrival spine for its inserts. Correct the docstring that
promised a far-history backfill that does not exist: the hourly window imports
about 48 hours and nothing deeper.
Strava now enqueues its history backfill at connect time, mirroring the WHOOP
and Fitbit callbacks, so deep history imports within the hour instead of waiting
for the next worker restart.
Parity suite proves a Polar exercise and an equivalent Strava activity map to a
downstream-indistinguishable Workout row (sport bucket, start instant, duration,
distance, calories, HR, null-vs-zero). Regression guard asserts the exercises
request hits GET /v3/exercises with no userId path segment. Dedup ladder tests
mirror the Strava suite (overwrite-in-place, Apple+Polar twin collapses, Polar
above Strava). Composite test proves a failure in one Polar leg leaves the
other leg's result intact on the shared ledger. Defensive-shape tests cover the
four flagged assumptions: numeric-vs-string id, UTC-offset composition (positive
and negative), bare-array-vs-paged body, and a 403 scope error as a soft error.

Pull the athlete's exercises from the stateless GET /v3/exercises list (last
30 days of uploads, no transaction, no userId in the path) and upsert each into
the Workout table as source POLAR, keyed on (userId, source, externalId) so a
re-fetch or Polar-side re-analysis overwrites in place. A new table-driven
sport map normalises the raw Polar sport labels into the canonical
WorkoutSportType bucket at ingest, mirroring the Strava/WHOOP mappers; the raw
labels and training load ride metadata for provenance.
The exercise leg rides the existing hourly polar-sync cohort tick alongside the
vitals leg, with independent attribution on the shared polar ledger: each leg
is attempted and records its own failure, and neither can mask the other's
result. Polar takes its place in the workout source ladder between Withings and
Strava. No migration and no OpenAPI change: MeasurementSource.POLAR and the
full workouts source enum already exist.
