Six provider syncs returned a bare count, which narrowed their failures away:
a Nightscout window in which every SGV row was refused by a constraint
returned the same 0 as a quiet night, and an Oura or Polar run whose
collections all failed returned 0 too. The routes then answered 200 with a
count and the settings card drew a green tick over it.
Every sync now reports what it imported AND whether any part of it did not
land, and the route resolves the outcome server-side so the web card and the
native client cannot disagree. Google Health keeps its 502 for a run that
failed and wrote nothing, but a run that failed after writing some resources
is now a partial rather than a discarded result. The labs OCR commit carries
the same resolved outcome.
These four were the only connected providers with no way to ask for a
sync; they ran on their scheduled pass and nothing else. Each gets a POST
sync route on the hardened Fitbit and Google Health template: session auth,
a 5-per-minute per-user bucket, and a fixed 502 on failure. No body and no
full-sync flag, because none of the four entry points has a full-history
arm to call. Polar goes through the shared legs entry point so both legs
run with the attribution rules built for them.
The Nightscout error arm is the one that matters: a base URL carries the
API token as a query parameter, so the caught message can hold the user's
secret and never reaches the response body. The classified failure is
already on the ledger, recorded with the provider's own redaction.
Connecting also starts the first sync now. The poll handler has accepted a
single-user payload since it was written and never had a producer, so a
fresh connection sat empty for up to an hour waiting for the schedule. The
Oura and Polar callbacks and the Nightscout connect route enqueue one
targeted job each, best effort, with the hourly tick still the safety net.
Strava needs none: its callback already enqueues the history backfill,
which covers the recent window.
The four poll-queue names move into their own module so a request-path
caller can name a queue without dragging the whole worker handler graph
into the request bundle, following the backfill-queue precedent. Creation,
scheduling and handler binding stay in the registrar, and the dead-queue
guard follows the declarations.
