Editing a schedule's times no longer rewrites the past. Each material change archives the outgoing cadence as a dated revision, and every band consumer — history, compliance, write attribution, the auto-miss cutoff — mints past periods from the schedule that was valid at the time, so a dose era taken at its then-correct times stays on time forever. The repair script can infer historical eras from consistent old anchors behind an explicit flag. The welcome tour scrolls its target into view, flips above it when space below runs out and falls back to a centred sheet on any viewport, so no step can strand its buttons below the fold. The avatar menu drops the about entry — that lives in settings.

-- v1.16.3 — schedule-revision archive (effective dating).
|
|
--
|
|
-- A medication whose schedule times are edited used to lose its history: the
|
|
-- wholesale replace (deleteMany + create) left only the CURRENT rows, so
|
|
-- bands for PAST days were minted from the new times — the entire old era
|
|
-- read "unscheduled" and the new times' past slots read "missed".
|
|
--
|
|
-- This table archives each SUPERSEDED schedule state as one revision row
|
|
-- covering `[valid_from, valid_until)`. The LIVE rows stay in
|
|
-- `medication_schedules`; a revision never describes the current state, so
|
|
-- `valid_until` is NOT NULL by construction. `payload` holds the full
|
|
-- snapshot of the replaced schedule rows (timesOfDay, windows, cadence
|
|
-- fields, doseWindows, label, dose, reminderGraceMinutes) — enough to
|
|
-- rebuild the canonical schedule list for era minting.
|
|
--
|
|
-- `starts_on` stays the global floor: the first era begins at
|
|
-- max(medication.created_at, starts_on).
|
|
--
|
|
-- Additive + non-destructive: a new empty table; no existing row changes.
