feat: entity relationship refactor — notification trackers, command system, chat actions

Rework entity schema: rename Tracker→NotificationTracker, add CommandConfig/
CommandTracker/CommandTrackerListener entities for decoupled command handling.
Commands now resolve through CommandTracker→CommandConfig instead of
TelegramBot.commands_config. Smart ref-counted bot polling based on active
listeners. Add chat_action to telegram targets. Full frontend CRUD pages
for command configs and command trackers. Idempotent SQLite migrations.

+# Feature Context: Entity Relationship Refactor
+
+## Current State
+Starting — no changes made yet. Branch created from master with all telegram-commands work merged.
+
+## Key Design Decisions
+- Provider capabilities (notifications, commands) inferred from provider type config, not explicit DB flags
+- Tracker renamed to NotificationTracker; TrackerTarget renamed to NotificationTrackerTarget
+- New entities: CommandConfig, CommandTracker, CommandTrackerListener
+- CommandConfig is provider_type-scoped, shareable across multiple CommandTrackers
+- CommandTrackerListener is a junction table (command_tracker_id, listener_type, listener_id) for extensibility
+- TelegramBot is dual-purpose: notification target backend + commands listener
+- TelegramBot polling/webhook lifecycle tied to CommandTrackerListener ref-counting
+- Telegram targets gain chat_action field
+- commands_config moves from TelegramBot to CommandConfig entity
+
+## Entity Schema (Target State)
+```
+ServiceProvider (type: "immich" → infers has_notifications=true, has_commands=true)
+  │
+  ├─ NotificationTracker (renamed from Tracker)
+  │   └─ NotificationTrackerTarget (renamed from TrackerTarget)
+  │       ├─ NotificationTarget (+ chat_action for telegram type)
+  │       ├─ TrackingConfig (unchanged)
+  │       └─ TemplateConfig (unchanged)
+  │
+  └─ CommandTracker (new)
+      ├─ CommandConfig (new, shared, provider_type-scoped)
+      └─ CommandTrackerListener (junction → listener_type + listener_id)
+          └─ TelegramBot as "telegram_bot" listener type
+
+TelegramBot
+  ├─ Used by NotificationTarget (sending messages)
+  └─ Used by CommandTrackerListener (receiving commands)
+      └─ Smart ref-counting: start polling/webhook when first listener added, stop when last removed
+```
+
+## Temporary Workarounds
+None yet.
+
+## Cross-Phase Dependencies
+- Phase 2 depends on Phase 1 (renamed models)
+- Phase 3 depends on Phase 1 (new models for CommandConfig, CommandTracker, CommandTrackerListener)
+- Phase 4 depends on Phase 3 (command entities exist in DB/API)
+- Phase 5 depends on Phase 2 (renamed API endpoints)
+- Phase 6 depends on Phase 3 (command entity APIs)
+- Phase 7 depends on all prior phases
+
+## Implementation Notes
+- SQLite + async SQLAlchemy via sqlmodel — table renames done via idempotent ALTER TABLE / CREATE TABLE
+- No formal test suite — verification via server startup + health check + frontend build
+- Migration must handle existing data: rename tables, migrate TelegramBot.commands_config → CommandConfig rows
+- Incremental strategy: each phase leaves the codebase fully working

+# Feature: Entity Relationship Refactor
+
+**Branch:** `feature/entity-relationship-refactor`
+**Base branch:** `master`
+**Created:** 2026-03-20
+**Status:** ✅ Complete
+**Strategy:** Incremental
+**Mode:** Automated
+**Execution:** Orchestrator
+
+## Summary
+
+Rework the entity schema so that ServiceProvider capabilities (notifications, commands) are
+inferred from provider type config. Current Trackers become NotificationTrackers. A new
+CommandTracker entity links providers to CommandConfigs and CommandsListeners (TelegramBot
+as first implementation). TelegramBot becomes dual-purpose: notification target backend +
+commands listener with smart ref-counted polling/webhook. CommandConfig is a new shareable
+entity scoped to provider type. Telegram targets gain a chat_action setting.
+
+## Build & Test Commands
+- **Build (backend):** `cd packages/server && pip install -e .`
+- **Verify (backend):** Server startup + `curl -s http://localhost:8420/api/health`
+- **Build (frontend):** `cd frontend && npm install && npx vite build`
+- **Test:** No automated test suite yet — verification via server startup and frontend build

+# Phase 1: Database Schema & Migration
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** backend
+
+## Objective
+Add new database models (CommandConfig, CommandTracker, CommandTrackerListener), rename
+existing models (Tracker → NotificationTracker, TrackerTarget → NotificationTrackerTarget),
+add chat_action to NotificationTarget, and write idempotent migration logic.
+
+## Tasks
+
+- [ ] Task 1: Rename `Tracker` model to `NotificationTracker` — update class name, `__tablename__` to `"notification_tracker"`, and all field references. Keep all existing fields (provider_id, collection_ids, scan_interval, batch_duration, enabled, etc.)
+- [ ] Task 2: Rename `TrackerTarget` model to `NotificationTrackerTarget` — update class name, `__tablename__` to `"notification_tracker_target"`, rename `tracker_id` FK to `notification_tracker_id`
+- [ ] Task 3: Rename `TrackerState` model to `NotificationTrackerState` — update class name, `__tablename__` to `"notification_tracker_state"`, rename `tracker_id` FK to `notification_tracker_id`
+- [ ] Task 4: Add `chat_action` optional string field to `NotificationTarget` model (for telegram targets, e.g. "typing", "upload_photo")
+- [ ] Task 5: Create `CommandConfig` model — fields: id, user_id (FK→User), provider_type (str), name, icon, enabled_commands (JSON list), locale (str, default "en"), response_mode (str, default "media"), default_count (int, default 5), rate_limits (JSON dict), created_at
+- [ ] Task 6: Create `CommandTracker` model — fields: id, user_id (FK→User), provider_id (FK→ServiceProvider), command_config_id (FK→CommandConfig), name, icon, enabled (bool), created_at
+- [ ] Task 7: Create `CommandTrackerListener` model — fields: id, command_tracker_id (FK→CommandTracker), listener_type (str, e.g. "telegram_bot"), listener_id (int), created_at. Add unique constraint on (command_tracker_id, listener_type, listener_id)
+- [ ] Task 8: Remove `commands_config` field from `TelegramBot` model (will be migrated to CommandConfig)
+- [ ] Task 9: Remove `commands_config` field from `TrackerTarget`/`NotificationTrackerTarget` model
+- [ ] Task 10: Write idempotent migration in `migrations.py`:
+  - Rename table `tracker` → `notification_tracker`
+  - Rename table `tracker_target` → `notification_tracker_target` and rename column `tracker_id` → `notification_tracker_id`
+  - Rename table `tracker_state` → `notification_tracker_state` and rename column `tracker_id` → `notification_tracker_id`
+  - Add `chat_action` column to `notification_target`
+  - Create `command_config` table
+  - Create `command_tracker` table
+  - Create `command_tracker_listener` table
+  - Migrate existing `TelegramBot.commands_config` JSON → `CommandConfig` rows (one per bot that has non-default config)
+  - Drop `commands_config` column from old telegram_bot table
+  - Drop `commands_config` column from notification_tracker_target table
+- [ ] Task 11: Update all model imports in `models.py` `__init__` / re-exports — ensure other modules can still import the models
+- [ ] Task 12: Update `EventLog` model — rename `tracker_id` field to `notification_tracker_id` (nullable FK), add migration for column rename
+
+## Files to Modify/Create
+- `packages/server/src/notify_bridge_server/database/models.py` — rename models, add new models, remove fields
+- `packages/server/src/notify_bridge_server/database/migrations.py` — add migration functions
+
+## Acceptance Criteria
+- All new tables are created on startup via migration
+- Existing data is preserved and migrated (table renames, column renames, commands_config → CommandConfig)
+- Server starts without errors with existing test-data database
+- All existing imports still resolve (may need temporary aliases)
+
+## Notes
+- SQLite does not support `ALTER TABLE RENAME COLUMN` in older versions. Use the existing pattern of adding new columns + copying data if needed.
+- The migration must be idempotent — safe to run multiple times.
+- Other modules (API routes, services) will still reference old model names after this phase. That's OK — Phase 2 will update the API layer. For now, add Python-level aliases (e.g., `Tracker = NotificationTracker`) so existing code continues to work.
+- TrackerTarget.commands_config was unused in practice — safe to drop without data loss.
+
+## Review Checklist
+- [ ] All tasks completed
+- [ ] Code follows project conventions
+- [ ] No unintended side effects
+- [ ] Build passes
+- [ ] Tests pass (new + existing)

+# Phase 2: Notification Tracker Rename (API)
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** backend
+
+## Objective
+Rename all tracker-related API routes, service functions, and internal references to use
+"notification_tracker" naming. Add chat_action support to the targets API. Ensure the
+watcher, scheduler, and notifier services work with the renamed models.
+
+## Tasks
+
+- [ ] Task 1: Rename `api/trackers.py` → `api/notification_trackers.py`. Update all route paths from `/api/trackers` to `/api/notification-trackers`. Update function names (e.g., `list_trackers` → `list_notification_trackers`). Update all model references to use `NotificationTracker`.
+- [ ] Task 2: Rename `api/tracker_targets.py` → `api/notification_tracker_targets.py`. Update route paths from `/api/tracker-targets` to `/api/notification-tracker-targets`. Update model references to `NotificationTrackerTarget`, field references to `notification_tracker_id`.
+- [ ] Task 3: Update `api/targets.py` — add `chat_action` to create/update request schemas and response serialization for telegram-type targets.
+- [ ] Task 4: Update `services/watcher.py` — replace all `Tracker` references with `NotificationTracker`, `TrackerTarget` with `NotificationTrackerTarget`, `TrackerState` with `NotificationTrackerState`, `tracker_id` with `notification_tracker_id` where applicable.
+- [ ] Task 5: Update `services/scheduler.py` — rename tracker job references, function parameters, and log messages to use notification_tracker naming.
+- [ ] Task 6: Update `services/notifier.py` — update model references and any tracker-related parameter names.
+- [ ] Task 7: Update `main.py` — change router imports and registration to use new module names and route prefixes.
+- [ ] Task 8: Update `api/status.py` — rename any tracker count queries to use new model names.
+- [ ] Task 9: Update `commands/handler.py` — update any tracker model references used for command context resolution.
+- [ ] Task 10: Update `commands/webhook.py` — update any tracker model references.
+- [ ] Task 11: Update `services/telegram_poller.py` — update any tracker model references.
+- [ ] Task 12: Remove backward-compatibility aliases from models.py (if added in Phase 1) — all consumers now use new names.
+
+## Files to Modify/Create
+- `packages/server/src/notify_bridge_server/api/trackers.py` → rename to `notification_trackers.py`
+- `packages/server/src/notify_bridge_server/api/tracker_targets.py` → rename to `notification_tracker_targets.py`
+- `packages/server/src/notify_bridge_server/api/targets.py` — add chat_action
+- `packages/server/src/notify_bridge_server/services/watcher.py` — model name updates
+- `packages/server/src/notify_bridge_server/services/scheduler.py` — model name updates
+- `packages/server/src/notify_bridge_server/services/notifier.py` — model name updates
+- `packages/server/src/notify_bridge_server/main.py` — router registration
+- `packages/server/src/notify_bridge_server/api/status.py` — model name updates
+- `packages/server/src/notify_bridge_server/commands/handler.py` — model references
+- `packages/server/src/notify_bridge_server/commands/webhook.py` — model references
+- `packages/server/src/notify_bridge_server/services/telegram_poller.py` — model references
+
+## Acceptance Criteria
+- All API routes work under new `/api/notification-trackers` and `/api/notification-tracker-targets` paths
+- Old `/api/trackers` routes no longer exist
+- Telegram targets accept and return `chat_action` field
+- Server starts and health check passes
+- Watcher/scheduler/notifier services function correctly with renamed models
+
+## Notes
+- This is a breaking API change — frontend will need updating in Phase 5.
+- The watcher service is the most complex consumer of tracker models — test carefully.
+- The EventLog model references notification_tracker_id (renamed in Phase 1).

+# Phase 3: CommandConfig & CommandTracker CRUD API
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** backend
+
+## Objective
+Create full CRUD API routes for CommandConfig, CommandTracker, and CommandTrackerListener
+management. These endpoints let users create command configurations (scoped to provider type),
+create command trackers that link a provider to a command config, and attach/detach listeners
+(telegram bots) to command trackers.
+
+## Tasks
+
+- [ ] Task 1: Create `api/command_configs.py` with CRUD routes:
+  - `GET /api/command-configs` — list all for current user (+ system defaults with user_id=0)
+  - `POST /api/command-configs` — create new (validate provider_type, enabled_commands against registry)
+  - `GET /api/command-configs/{id}` — get single
+  - `PUT /api/command-configs/{id}` — update (validate ownership)
+  - `DELETE /api/command-configs/{id}` — delete (check not in use by any command tracker)
+  - Response should include all fields: id, user_id, provider_type, name, icon, enabled_commands, locale, response_mode, default_count, rate_limits, created_at
+
+- [ ] Task 2: Create `api/command_trackers.py` with CRUD routes:
+  - `GET /api/command-trackers` — list all for current user, include linked listeners count
+  - `POST /api/command-trackers` — create new (validate provider_id exists, command_config_id exists, provider_type matches between provider and config)
+  - `GET /api/command-trackers/{id}` — get single with listeners
+  - `PUT /api/command-trackers/{id}` — update (name, icon, enabled, command_config_id — validate provider_type match)
+  - `DELETE /api/command-trackers/{id}` — delete (cascade delete listeners)
+  - `POST /api/command-trackers/{id}/enable` — enable
+  - `POST /api/command-trackers/{id}/disable` — disable
+
+- [ ] Task 3: Add listener management endpoints to command_trackers.py:
+  - `GET /api/command-trackers/{id}/listeners` — list listeners for a command tracker
+  - `POST /api/command-trackers/{id}/listeners` — add listener (body: {listener_type, listener_id}). Validate: listener exists (e.g., TelegramBot with that ID), no duplicate (unique constraint), user owns the listener.
+  - `DELETE /api/command-trackers/{id}/listeners/{listener_id}` — remove listener
+
+- [ ] Task 4: Add validation helpers:
+  - Validate `enabled_commands` against `commands/registry.py` known commands for the given provider_type
+  - Validate `provider_type` match: CommandConfig.provider_type must match ServiceProvider.type of the CommandTracker's provider
+  - Validate listener ownership: user must own the TelegramBot being attached
+
+- [ ] Task 5: Register new routers in `main.py`
+
+- [ ] Task 6: Update `api/telegram_bots.py` — remove the commands config endpoints (POST `/telegram-bots/{id}/commands`, GET `/telegram-bots/{id}/commands`) since commands config now lives in CommandConfig entity. Keep the sync-commands endpoint but update it to accept a command_config_id parameter or read from command trackers.
+
+## Files to Modify/Create
+- `packages/server/src/notify_bridge_server/api/command_configs.py` — new file
+- `packages/server/src/notify_bridge_server/api/command_trackers.py` — new file
+- `packages/server/src/notify_bridge_server/main.py` — register new routers
+- `packages/server/src/notify_bridge_server/api/telegram_bots.py` — remove old commands config endpoints
+
+## Acceptance Criteria
+- Full CRUD for CommandConfig with provider_type validation
+- Full CRUD for CommandTracker with provider↔config type matching
+- Listener add/remove with ownership validation and uniqueness
+- Old telegram bot commands config endpoints removed
+- Server starts and all new endpoints respond correctly
+
+## Notes
+- The command registry currently defines commands globally. In future, commands could be provider-scoped. For now, validate enabled_commands against the flat registry list.
+- CommandConfig with user_id=0 could serve as system defaults (like TemplateConfig), but this is optional for Phase 3.
+- The sync-commands endpoint on TelegramBot may need to resolve which commands to sync from attached CommandTrackers — this is wired up in Phase 4.
+

+- [ ] Code follows project conventions
+- [ ] No unintended side effects

+# Phase 4: Command System Refactor
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** backend
+
+## Objective
+Refactor the command handling system to resolve commands through CommandTracker → CommandConfig
+instead of TelegramBot.commands_config. Implement smart ref-counted polling/webhook management
+for TelegramBot when used as a commands listener. Handle multi-tracker routing (one bot serving
+multiple command trackers for different providers).
+
+## Tasks
+
+- [ ] Task 1: Refactor `commands/handler.py` — `handle_command()`:
+  - Instead of reading `bot.commands_config`, resolve command config through CommandTrackerListeners:
+    1. Find all CommandTrackerListener rows where listener_type="telegram_bot" AND listener_id=bot.id
+    2. Load the associated CommandTracker for each (filter enabled=True)
+    3. Load CommandConfig for each tracker
+    4. Load ServiceProvider for each tracker
+  - For each incoming command, check which CommandConfig(s) have it enabled
+  - If multiple trackers enable the same command (e.g., two Immich providers with /latest), use the first match or let the user disambiguate (future enhancement — for now, use first enabled match)
+  - Pass the resolved provider config to command execution functions
+
+- [ ] Task 2: Update `_get_bot_context()` in handler.py:
+  - Currently finds trackers/providers by matching bot_token in notification target configs
+  - New approach: resolve through CommandTracker → provider_id → ServiceProvider
+  - Return a list of (command_tracker, command_config, provider) tuples
+
+- [ ] Task 3: Implement smart ref-counted polling/webhook in `services/telegram_poller.py`:
+  - Track active listener count per bot: when a CommandTrackerListener is added for a bot, increment ref count; when removed, decrement
+  - `start_bot_if_needed(bot_id)` — start polling/webhook only if not already running
+  - `stop_bot_if_unused(bot_id)` — stop polling/webhook only if ref count reaches 0
+  - Export these functions for use by the command_trackers API (when adding/removing listeners)
+
+- [ ] Task 4: Update `commands/webhook.py`:
+  - Webhook handler already receives messages for a specific bot (by webhook_path_id)
+  - Update to use the new command resolution flow from Task 1
+  - Ensure chat auto-discovery still works
+
+- [ ] Task 5: Update `services/scheduler.py`:
+  - On startup, instead of starting polling for all bots with update_mode="polling", start polling only for bots that have active CommandTrackerListeners
+  - Use ref-counting logic from Task 3
+
+- [ ] Task 6: Update telegram bot sync-commands endpoint:
+  - `POST /api/telegram-bots/{id}/sync-commands` should now:
+    1. Find all CommandTrackerListeners for this bot
+    2. Collect all enabled commands across all linked CommandConfigs
+    3. Merge command lists (union of enabled commands)
+    4. Call setMyCommands with the merged list
+    5. Use locale from the first CommandConfig (or a bot-level default)
+
+- [ ] Task 7: Update `services/__init__.py` startup logic:
+  - On startup, enumerate all enabled CommandTrackers with listeners
+  - For each unique bot referenced, call `start_bot_if_needed(bot_id)`
+
+## Files to Modify/Create
+- `packages/server/src/notify_bridge_server/commands/handler.py` — new command resolution flow
+- `packages/server/src/notify_bridge_server/commands/webhook.py` — updated handler
+- `packages/server/src/notify_bridge_server/services/telegram_poller.py` — ref-counted polling
+- `packages/server/src/notify_bridge_server/services/scheduler.py` — startup logic
+- `packages/server/src/notify_bridge_server/services/__init__.py` — startup logic
+- `packages/server/src/notify_bridge_server/api/telegram_bots.py` — sync-commands update
+
+## Acceptance Criteria
+- Commands resolve through CommandTracker → CommandConfig instead of TelegramBot.commands_config
+- Bot polling/webhook starts only when at least one CommandTrackerListener references the bot
+- Bot polling/webhook stops when last listener is removed
+- Multiple command trackers can share the same bot — commands are merged
+- Telegram bot sync-commands syncs the merged command set
+- Existing command functionality (search, latest, random, etc.) still works end-to-end
+
+## Notes
+- Rate limiting can stay in-memory per (bot_id, chat_id, category) — no schema change needed.
+- The handler currently uses `_get_bot_context()` to find providers via notification targets. The new flow resolves providers via CommandTracker.provider_id — this is cleaner and decouples commands from notification targets.
+- Edge case: a bot with no CommandTrackerListeners should not poll/webhook. If a user deletes all command trackers referencing a bot, polling should stop.
+- Edge case: a command tracker can be disabled (enabled=False) — disabled trackers don't count for ref-counting.

+# Phase 5: Frontend — Rename & Restructure
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** frontend
+
+## Objective
+Rename all tracker-related frontend pages, routes, API calls, and i18n keys to use
+"notification tracker" naming. Add chat_action dropdown to telegram target form.
+Update navigation.
+
+## Tasks
+
+- [ ] Task 1: Rename route directory `frontend/src/routes/trackers/` → `frontend/src/routes/notification-trackers/`. Update `+page.svelte` to use new API endpoints (`/api/notification-trackers`, `/api/notification-tracker-targets`).
+
+- [ ] Task 2: Update `+layout.svelte` navigation:
+  - Change "Trackers" nav item to "Notification Trackers" (or shorter "Notif. Trackers") with route `/notification-trackers`
+  - Keep icon the same
+
+- [ ] Task 3: Update `frontend/src/lib/i18n/en.json`:
+  - Rename `tracker.*` keys to `notificationTracker.*`
+  - Rename `trackerTarget.*` keys to `notificationTrackerTarget.*`
+  - Add nav key: `nav.notificationTrackers`
+  - Add `targets.chatAction`, `targets.chatActionHelp` keys
+  - Remove old `tracker.*` keys
+
+- [ ] Task 4: Update `frontend/src/lib/i18n/ru.json` — same key renames as en.json with Russian translations
+
+- [ ] Task 5: Update `frontend/src/routes/targets/+page.svelte`:
+  - Add `chat_action` dropdown to telegram target form (options: none/typing/upload_photo/upload_video/upload_document/record_video/record_voice)
+  - Include chat_action in create/update API calls
+  - Display chat_action in target list if set
+
+- [ ] Task 6: Update `frontend/src/routes/notification-trackers/+page.svelte` (renamed from trackers):
+  - All API calls point to `/api/notification-trackers` and `/api/notification-tracker-targets`
+  - All variable names reflect "notificationTracker" naming
+  - i18n keys updated to new prefixes
+
+- [ ] Task 7: Update `frontend/src/routes/+page.svelte` (dashboard):
+  - Update any tracker references/stats to use new API endpoints and naming
+
+- [ ] Task 8: Update any other pages that reference trackers:
+  - `tracking-configs/+page.svelte` — update if it links to trackers
+  - `template-configs/+page.svelte` — update if it references trackers
+
+## Files to Modify/Create
+- `frontend/src/routes/trackers/+page.svelte` → move to `frontend/src/routes/notification-trackers/+page.svelte`
+- `frontend/src/routes/+layout.svelte` — nav updates
+- `frontend/src/lib/i18n/en.json` — key renames
+- `frontend/src/lib/i18n/ru.json` — key renames
+- `frontend/src/routes/targets/+page.svelte` — chat_action
+- `frontend/src/routes/+page.svelte` — dashboard updates
+
+## Acceptance Criteria
+- Navigation shows "Notification Trackers" linking to `/notification-trackers`
+- Notification trackers page works with renamed API endpoints
+- Telegram targets have chat_action dropdown
+- All i18n keys updated in both en and ru
+- Frontend builds without errors
+- No references to old `/api/trackers` endpoints remain
+
+## Notes
+- The old `/trackers` route should be removed entirely (no redirect needed — this is an admin tool).
+- chat_action values map to Telegram's sendChatAction API parameter.
+- Keep the UI structure the same — this is a rename, not a redesign.

+# Phase 6: Frontend — Command Entities
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** frontend
+
+## Objective
+Create new frontend pages for CommandConfig and CommandTracker management. Update the
+Telegram Bots page to remove inline commands config (now managed via CommandConfig entity)
+and show listener status instead.
+
+## Tasks
+
+- [ ] Task 1: Create `frontend/src/routes/command-configs/+page.svelte`:
+  - List view showing all command configs with name, provider_type badge, enabled command count, locale
+  - Create form: name, icon, provider_type selector, enabled_commands checkboxes (from registry), locale dropdown, response_mode dropdown, default_count slider, rate_limits inputs
+  - Edit/delete functionality
+  - Follow existing page patterns (show/hide form toggle, icon picker, confirm modal for delete)
+
+- [ ] Task 2: Create `frontend/src/routes/command-trackers/+page.svelte`:
+  - List view showing command trackers: name, provider name, command config name, listener count, enabled status
+  - Create form: name, icon, provider selector, command_config selector (filtered by matching provider_type), enabled toggle
+  - Edit/delete functionality
+  - Expandable section per tracker showing:
+    - Linked listeners with type badge and name
+    - "Add Listener" dropdown (select from user's telegram bots)
+    - Remove listener button per listener
+
+- [ ] Task 3: Update `frontend/src/routes/telegram-bots/+page.svelte`:
+  - Remove the "Commands" expandable section (command enable/disable checkboxes, locale, response_mode, default_count, rate_limits)
+  - Replace with "Listener Status" section showing:
+    - List of command trackers using this bot as a listener
+    - Each showing: tracker name, provider name, command config name, enabled status
+    - Link to command tracker page
+  - Keep: Chats section, Webhook section, Settings section (update_mode)
+
+- [ ] Task 4: Update `frontend/src/routes/+layout.svelte` navigation:
+  - Add "Command Configs" nav item (route `/command-configs`, icon: settings/cog)
+  - Add "Command Trackers" nav item (route `/command-trackers`, icon: terminal/command)
+  - Group navigation logically: Providers, Notification Trackers, Tracking, Templates, Targets, Bots | Command Trackers, Command Configs
+
+- [ ] Task 5: Update `frontend/src/lib/i18n/en.json`:
+  - Add `commandConfig.*` keys (title, form labels, validation messages)
+  - Add `commandTracker.*` keys (title, form labels, listener management)
+  - Add `nav.commandConfigs`, `nav.commandTrackers` keys
+  - Remove `telegramBot.commands*` keys (moved to commandConfig)
+
+- [ ] Task 6: Update `frontend/src/lib/i18n/ru.json` — same additions/removals as en.json with Russian translations
+
+- [ ] Task 7: Update `frontend/src/routes/+page.svelte` (dashboard):
+  - Add command tracker count/status to dashboard stats
+
+## Files to Modify/Create
+- `frontend/src/routes/command-configs/+page.svelte` — new page
+- `frontend/src/routes/command-trackers/+page.svelte` — new page
+- `frontend/src/routes/telegram-bots/+page.svelte` — remove commands section, add listener status
+- `frontend/src/routes/+layout.svelte` — navigation
+- `frontend/src/lib/i18n/en.json` — new keys
+- `frontend/src/lib/i18n/ru.json` — new keys
+- `frontend/src/routes/+page.svelte` — dashboard
+
+## Acceptance Criteria
+- CommandConfig page: full CRUD with provider_type filtering and command checkboxes
+- CommandTracker page: full CRUD with provider/config selection and listener management
+- Telegram Bots page: no more inline commands config, shows listener status instead
+- Navigation includes new pages in logical grouping
+- Both i18n languages updated
+- Frontend builds without errors
+
+## Notes
+- Command checkboxes should show all 13 commands from the registry (help, status, albums, events, summary, latest, memory, random, search, find, person, place, favorites, people).
+- Provider_type filtering: when user selects a provider in CommandTracker form, only show CommandConfigs with matching provider_type.
+- The telegram bot "Sync with Telegram" button should remain — it now syncs commands from all linked command trackers.
+- Follow existing UI patterns closely (ConfirmModal, icon picker, collapsible sections, snackbar notifications).
+
+## Review Checklist
+- [ ] All tasks completed
+- [ ] Code follows project conventions
+- [ ] No unintended side effects
+- [ ] Build passes
+- [ ] Tests pass (new + existing)

+# Phase 7: Integration & Cleanup
+
+**Status:** ⬜ Not Started
+**Parent plan:** [PLAN.md](./PLAN.md)
+**Domain:** fullstack
+
+## Objective
+Final integration pass: verify end-to-end flows, clean up deprecated code paths,
+update CLAUDE.md entity relationship documentation, and ensure everything works
+together.
+
+## Tasks
+
+- [ ] Task 1: Verify notification flow end-to-end:
+  - ServiceProvider → NotificationTracker → NotificationTrackerTarget → NotificationTarget
+  - Watcher detects changes → dispatches through renamed entities
+  - Scheduled/periodic/memory notifications still work
+
+- [ ] Task 2: Verify command flow end-to-end:
+  - CommandTracker → CommandConfig + CommandTrackerListener (TelegramBot)
+  - Incoming command via webhook/polling → resolved through command tracker
+  - Bot ref-counting: start/stop polling based on listener count
+
+- [ ] Task 3: Clean up deprecated code:
+  - Remove any remaining backward-compatibility aliases in models.py
+  - Remove any old route files that were renamed (trackers.py, tracker_targets.py)
+  - Remove any unused imports
+  - Ensure no references to old model names remain anywhere
+
+- [ ] Task 4: Update CLAUDE.md "Entity Relationships" section:
+  - Document new schema: ServiceProvider capabilities, NotificationTracker, CommandTracker, CommandConfig, CommandTrackerListener
+  - Update the entity relationship diagram
+  - Update Template System Sync Rules if affected
+
+- [ ] Task 5: Verify migration idempotency:
+  - Fresh database: all tables created correctly
+  - Existing database with old schema: migration runs without errors, data preserved
+  - Running migration twice: no errors
+
+- [ ] Task 6: Clean up any TODO markers left by previous phases
+
+- [ ] Task 7: Verify frontend-backend integration:
+  - All frontend pages load and display data correctly
+  - CRUD operations work for all entities
+  - Command tracker listener add/remove triggers bot polling start/stop
+
+## Files to Modify/Create
+- `packages/server/src/notify_bridge_server/database/models.py` — cleanup aliases
+- `CLAUDE.md` — update entity relationships documentation
+- Various files — cleanup TODOs and unused code
+
+## Acceptance Criteria
+- Full notification flow works: provider → notification tracker → target
+- Full command flow works: command tracker → command config → listener → bot
+- No references to old model/route names remain
+- CLAUDE.md accurately documents new entity schema
+- Server starts cleanly with both fresh and migrated databases
+- Frontend builds and all pages functional
+
+## Notes
+- This phase is primarily verification and cleanup — no major new features.
+- If integration issues are found, fix them in this phase rather than going back.
+- The old plans/entity-relationship-refactor/ files from previous attempts can be kept as historical record.
+
+## Review Checklist
+- [ ] All tasks completed
+- [ ] Code follows project conventions
+- [ ] No unintended side effects
+- [ ] Build passes
+- [ ] Tests pass (new + existing)
