- DB: tasks table with scheduled_datetime, reminder_minutes_before, advance_notified, status
- API: CRUD routes GET/POST /api/tasks, PATCH/DELETE /api/tasks/<id>
- Scheduler: check_task_reminders() fires advance + at-time notifications, tracks advance_notified to prevent double-fire
- Bot: handle_task() with add/list/done/cancel/delete actions + datetime resolution helper
- AI: task interaction type + examples added to command_parser
- Web: task list page with overdue/notified color coding + new task form with datetime-local picker
- Nav: replaced Templates with Tasks in bottom nav

1. config/schema.sql — Added timezone_name VARCHAR(100) to user_preferences table + an ALTER TABLE migration at the bottom for existing DBs.
2. core/tz.py — Rewrote with dual-path timezone support:
- Request context: _get_request_tz() now checks X-Timezone-Name header (IANA) first, falls back to X-Timezone-Offset
- Background jobs: New tz_for_user(user_uuid) and user_now_for(user_uuid) read stored timezone_name from prefs, fall back to numeric offset, then UTC
- All existing function signatures (user_now(), user_today()) preserved for backward compat
3. scheduler/daemon.py — Fixed 3 bugs:
- _user_now_for() now delegates to tz.user_now_for() which uses IANA timezone names (DST-safe)
- check_nagging() — replaced datetime.utcnow() with _user_now_for(user_uuid) so nags evaluate in user's timezone
- poll_callback() — replaced single UTC midnight check with _check_per_user_midnight_schedules() that iterates users and creates daily schedules at their local midnight
4. api/routes/preferences.py — Added "timezone_name" to allowed PUT fields.
5. synculous-client/src/lib/api.ts — Added X-Timezone-Name header to every request + added timezone_name to preferences update type.
6. synculous-client/src/app/dashboard/layout.tsx — Now syncs both timezone_offset and timezone_name (via Intl.DateTimeFormat().resolvedOptions().timeZone) on session start.
- Added PomodoroTimer component with work/break modes
- Timer appears as icon in header, expands to full widget on click
- Supports 25m work, 5m short break, 15m long break cycles
- Shows progress bar, cycle dots, and mode switcher
- Plays sound when timer completes
- Can be minimized while running (shows pulsing indicator)
- Add all 14 missing database tables (medications, med_logs, routines, etc.)
- Rewrite medication scheduling: support specific days, every N days, as-needed (PRN)
- Fix taken_times matching: match by created_at date, not scheduled_time string
- Fix adherence calculation: taken / expected doses, not taken / (taken + skipped)
- Add formatSchedule() helper for readable display
- Update client types and API layer
- Rename brilli-ins-client → synculous-client
- Make client PWA: add manifest, service worker, icons
- Bind dev server to 0.0.0.0 for network access
