A reading sent with a measurements:write token keeps its EXTERNAL source
and now points at the token that carried it (measurements.ingest_token_id).
Every stored row answers a server-resolved appleHealthMirror: true for
WITHINGS, IMPORT and MANUAL, the token's choice for EXTERNAL, false
otherwise. The plain list accepts appleHealthMirror=true so a client can
page exactly those rows.
Migration 0476 adds the columns and links existing EXTERNAL readings only
where one measurement token provably sent them; 0477 builds the index
concurrently. Backups carry the link and a restore keeps it only for a
token the account still holds. A guard holds every EXTERNAL writer to
setting the link.
Work a request starts and does not wait for runs inside the request's
context, so an annotate({ action }) from it landed on the request's event
whenever it ran before the event was emitted. The measurement tail's
status re-warm logged a hand-entered reading as
insights.status.invalidate.skipped on some requests and as
measurement.create on others.
runDetached starts such work so that its action is dropped for the event
it was detached from; meta, warnings and the auth it reads stay as they
were, and an event the work opens for itself keeps its own action.
fireAndForget now takes a function and starts it detached, and every
trackBackgroundTask handle on a request path is built with runDetached,
which a structural guard holds.
GET /api/measurements keeps authentication and the query refusal and hands
the validated query to measurementListResponse (lib/measurements/list),
which tries the list modes in their old order. POST keeps authentication,
the body, the bridge-source refusal and the three validation answers; the
single and combined writes with their shared tail move to
lib/measurements/create/create-readings.ts, the named sleep-stage write to
create-sleep-stage.ts. The route falls from 938 to 274 lines.
The parity walk recorded before the move is unchanged; the guards that name
the measurement writers, the write tail and the bounded reads follow the
code.
