closes#36
The deletion has existed since Batch 01 with an instrumented test and no way to
reach it. This adds the Privacy & Security section, a confirmation that says
what goes and what stays, and PrivacyViewModelTest.
A PRIVACY CONTROL WHOSE LABEL DID NOTHING
The confirmation promises "your reminder settings are unchanged". Proving that
meant changing a setting first, so I tapped "Maximum privacy" on a device and
nothing happened: PrivacyRow and onboarding's PrivacyOption both put onClick on
the RadioButton and left the row inert. The option that decides what a lock
screen shows could only be changed by hitting a 20dp circle — in both places a
user ever chooses it.
Modifier.selectable on the row, onClick = null on the radio. That is Material's
documented pattern and it also merges the semantics, so TalkBack announces one
selectable option instead of a radio button and two loose strings.
Found by trying to verify a different claim, which is the argument for verifying
claims rather than asserting them. The setting does survive deletion — set to
Maximum privacy, deleted everything, still Maximum privacy.
A DESIGN THAT WAS WRONG BEFORE IT WAS WRITTEN
The first draft cancelled the reminder schedule on delete. Seems obviously
right; is not. ReminderWorker reads the forecast each run and NoData maps to no
decision, so scheduled work already does nothing while there is nothing to say —
and scheduling only happens from ReminderCoordinator and the settings screen, so
cancelling would have left reminders silently off until the user next toggled
something, long after logging a new period. Checked the call sites instead of
reasoning from the name.
Delete touches health data only. UserPreferences is a separate store precisely
so a privacy action cannot reset a choice somebody made, and there is no undo —
§45 says irreversible, and an undo snackbar keeps the data alive for its
timeout.
Round 4 recorded in docs/qa/. 194 tests pass; ./gradlew check, schema-guard and
doc-claims all pass. Driven on PeriodMinSdk26.
