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

- Migration v0.68: seeds advisory_non_bill_filters (5k+ patterns) and
advisory_bill_like_overrides (83 override terms) on first startup.
Idempotent — skips if already seeded.
- advisoryFilterService.js: lazy in-memory cache checks override terms
first, then scans patterns. Returns null | {confidence, category, rationale}.
- Transaction list: each row gets advisory_filter from the server.
- High-confidence unmatched transactions: show 'Probably not a bill'
italic text instead of 'No bill linked'.
- MatchBillDialog high confidence: 'Create Bill' replaced with
'Probably not a bill · create anyway' text link for manual override.
- MatchBillDialog medium confidence: Create Bill button renders muted.
- Same logic in empty-state CTA when search returns no results.
- BillModal onSave now returns the saved bill so callers can auto-match.
- Bump v0.33.7.3 -> v0.33.8.0
The index referenced transaction_id which is only added by migration v0.59.
On existing databases CREATE TABLE IF NOT EXISTS is a no-op, so the index
creation crashed before migrations could run. v0.61 creates it correctly
after the column exists. Fresh installs still get it via normal migration.
Added subscription metadata to bills: is_subscription, type, reminder_days, source, detected_at
Backend subscription API (routes/subscriptions.js)
SimpleFIN recommendation logic (services/subscriptionService.js)
New /subscriptions page (client/pages/SubscriptionsPage.jsx)
Track-as-subscription controls in BillModal.jsx
Navigation under Tracker menu
