Three integration cases pinned the old behaviour: the sync handshake stamping
the checkpoint, and the calendar read persisting the prediction. Both are the
faults this release removes, so the cases were asserting a bug.
Each file now asserts the read writes nothing AND that the other end does. The
second half is not decoration: without it, "nothing was written" would pass
just as well against a column nothing writes at all.
The cycle case seeds its own history and its own profile row rather than
reaching a route to get one, because reaching the route is exactly what the
prediction must no longer depend on.
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.
Server-side prep for the next iOS TestFlight build. Five surfaces land together so the iOS engineer can pick them up in one cut-over: a locked externalId shape for daily-aggregated cumulative HealthKit rows, the SyncMode foundation columns + handshake + bulk-backfill endpoints, a first-class MoodEntry.note column that replaces the legacy tag-based workaround, a cross-source workout dedup helper, and two new MeasurementType enums plus the shared category overlay that drives the iOS permission picker and the future Insights nav.
