Replace all Save buttons on the Settings page with debounced auto-save:
- useAutoSave hook: debounce with latest-payload-wins, flush() for blur,
pending-edit flush on unmount, status machine (idle/saving/saved/error)
with saved fading back to idle. Covered by 6 Vitest tests (fake timers).
- SaveStatus pill (framer-motion) in the page header and notification card
headers — Saving…/Saved/Save failed.
- Timing per control: toggles/selects/channel ~150-400ms; typed inputs
(email, URLs, grace period, drift pct) 900ms + flush on blur.
- Push token never auto-saves mid-type: saves on blur only, so a partial
token can never overwrite a working one.
- Notification cards no longer refetch parent settings on save (would
clobber in-flight edits under auto-save).
- Decision: no undo toast — settings are non-destructive and instantly
re-editable; undo would add noise without safety.
- vitest include now picks up .jsx tests; jsdom + @testing-library/react
added as devDependencies.
Detects when a bill's recent payments have diverged from its configured
expected amount for 2+ consecutive months and surfaces it in a new
collapsible amber panel on the Tracker page.
- Migration v0.71: adds `drift_snoozed_until` to bills and
`notify_amount_change` to users
- New `driftService.getDriftReport()`: computes per-bill payment median
over last 3 months, flags drift above a user-configurable threshold
(default 5%, minimum $1 delta)
- New `GET /api/bills/drift-report` and `POST /api/bills/:id/snooze-drift`
routes (registered before `/:id` to avoid routing conflict)
- `runDriftNotifications()` added to daily worker — sends amber digest
email per user listing all changed bills with old → new amounts
- `notify_amount_change` wired through profile and notifications routes
- `DriftInsightPanel`: collapsible amber panel with per-bill
strikethrough old → new amount, ±% badge, TrendingUp/TrendingDown
icons, "Update to $X.XX" (with undo toast) and "Dismiss" (30 days)
actions; teal palette for price decreases
- `drift_threshold_pct` setting added to SettingsPage Billing Behavior
- "Notify on price changes" toggle added to ProfilePage notifications
