ci: isolate test backend install in venv

The persistent Gitea runner caches the setup-python toolcache between
runs. A previous run that produced wheels with broken metadata (no
Version field in METADATA) left a notify-bridge-server install with
no RECORD file in site-packages. The next run hits:

  Found existing installation: notify-bridge-server None
  error: uninstall-no-record-file

pip refuses to uninstall (no RECORD) and refuses to overlay (it tries
to uninstall first). Switching from a system-pip install into the
toolcache to an isolated /tmp/venv per run sidesteps the leak — each
CI run starts with empty site-packages.

Same change to build.yml and release.yml so the pre-merge gate and
the release-gate both run the same setup.

+# Feature Backlog
+
+Curated feature ideas, narrowed from a brainstorming pass on 2026-05-13.
+Order is **rough sequencing preference**, not strict priority — adjust as we go.
+
+---
+
+## 1. Quiet Hours — close the gaps in the existing system
+
+**Reality check (verified 2026-05-13).** Quiet hours are already shipped under
+the "deferred dispatch" name in v0.8.0. The pipeline lives at
+`packages/server/src/notify_bridge_server/services/deferred_dispatch.py` with
+helpers in `dispatch_helpers.py` and tests in
+`tests/test_deferred_dispatch.py`. What exists:
+
+- Per-tracking-config window: `tracking_config.quiet_hours_enabled`,
+  `quiet_hours_start`, `quiet_hours_end`.
+- Per-link override: `notification_tracker_target.quiet_hours_start`,
+  `quiet_hours_end`.
+- Smart coalescing (asset add + asset remove during a window cancels each
+  other out, set-union merge for repeated adds).
+- Post-window drain via APScheduler one-shot date jobs.
+- Wall-clock event types (`scheduled_message`) drop instead of deferring.
+- Frontend status surface: `deferred`, `deferred_then_dropped`,
+  `deferred_then_failed`, with `deferred_until` and `deferred_for_seconds`
+  fields exposed in the event log.
+
+**What's NOT there (the actual gaps):**
+
+| Gap | Sketch |
+| --- | --- |
+| **Target-level windows** | Today, hours bind to the *watcher* (tracking config / link). Users naturally think of DND at the *destination* ("don't ping my phone at night, regardless of source"). New column on `notification_target` + dispatcher gate. |
+| **Multiple windows per row** | Today is a single HH:MM range. Real schedules want weekday-evening + weekend-all-day. JSON list of windows. |
+| **Days-of-week** | Same window every day. Need `days: ["mon", "tue", ...]` filter per window. |
+| **Per-window timezone** | Uses the global app TZ. Multi-traveller / multi-target setups want per-window TZ. |
+| **Silent mode** | Modes today are defer-or-drop. Telegram `disable_notification=true` ("send but don't ring") is a third useful mode. |
+| **Per-receiver windows** | One bot → multiple chats, each potentially with its own DND. Today it's all-or-nothing per target. |
+
+**Recommended cut for v1 of "extend quiet hours":**
+
+- Add target-level quiet hours (new column `notification_target.quiet_hours_json`
+  = list of `{days, start, end, mode, tz}`).
+- Modes: `drop`, `defer`, `silent`. `defer` reuses the existing
+  deferred-dispatch pipeline (just changes who decides). `silent` maps to
+  `disable_notification=true` for Telegram; other targets fall through to
+  normal send (or we treat `silent` as `defer` for non-Telegram targets — TBD).
+- Dispatcher precedence: target window wins over link/tracking-config window
+  when both are configured. Document this explicitly.
+- Frontend: new "Quiet hours" fieldset in the target editor (Aurora cassette
+  style). Reuses Timezone picker; new day-picker chip row.
+- Skip days-of-week + multi-window in v1 if scope grows — ship the target-level
+  cut first, then iterate.
+
+**Open questions.**
+
+- How exactly do target / link / tracking-config windows combine? Proposal:
+  any window covering "now" wins (drop > defer > silent precedence).
+- Should `silent` for non-Telegram targets degrade to normal send or to
+  defer? Defer is the safer default.
+- Does the event log need a new status (`silenced` / `dropped_by_target_qh`)
+  to make precedence visible?
+
+---
+
+## 2. Immich Smart Actions (expand beyond Auto-Organize)
+
+**What.** Extend the existing Smart Actions pattern (currently:
+**Immich Auto-Organize**) with more rule-driven actions against the Immich API.
+
+**Why.** Auto-Organize already proves the descriptor → rule editor → executor
+pipeline. Adding actions is mostly authoring new executors + small UI rule
+shapes, not new infra.
+
+**Candidates (pick in this order).**
+
+1. **Auto-favorite by person** — when an asset is detected containing person
+   X (or any of a set), mark it favorite.
+2. **Auto-archive by age / album** — assets older than N days in a given
+   album get archived. Pair with a "dry-run shows count" UX like
+   Auto-Organize already has.
+3. **Duplicate cluster nudge** — periodically run Immich's duplicate API and
+   send a digest notification with inline buttons ("review", "ignore for 30d").
+   Depends on inline-button work (see backlog item 4 dependencies).
+4. **Share-link rotation** — for an album, regenerate the share link every N
+   days; notify with the new URL.
+5. **Pending-delete review** — push a weekly digest of trash contents before
+   Immich's auto-purge fires.
+
+**Shape.**
+
+- Reuse the existing **action descriptor** layer
+  (`packages/core/src/notify_bridge_core/providers/actions.py`,
+  `action_executor.py`) and the frontend rule editor used by Auto-Organize.
+- Each new action = (a) executor in core, (b) rule schema in the descriptor,
+  (c) frontend descriptor extension for the rule editor fields.
+- Persist as `provider_actions` rows (already exists for Auto-Organize) with
+  a discriminator + JSON config.
+
+**Open questions.**
+
+- Does "auto-favorite by person" need a confirmation queue or run silently?
+  Default to silent + event_log entry.
+- How do we surface "this action moved/changed X assets" in the dashboard?
+  Probably a per-action stat tile on the provider detail page.
+
+---
+
+## 3. Home Assistant Provider
+
+**Full plan:** [feature-home-assistant.md](feature-home-assistant.md).
+
+**One-line summary.** New WebSocket-based service provider with a 3-phase
+ship: subscribe + dispatch (Phase 1), bot commands (Phase 2), HA service
+calls as Smart Actions (Phase 3). Chosen over webhook ingest because
+Phases 2 + 3 force a long-lived API connection anyway; consolidating on WS
+avoids a refactor.
+
+**Status:** planned, not started.
+
+---
+
+## 4. Block-Based Template Builder
+
+**What.** A visual, drag-and-drop builder for notification and command
+templates that compiles down to Jinja2. Lives alongside (not instead of) the
+current `JinjaEditor`. Author can flip between views.
+
+**Why.** The current Jinja editor is powerful but unforgiving. A block UI
+lowers the floor for new users and provides a discovery surface for the
+variables documented in `template_configs.py`.
+
+**Shape.**
+
+- Frontend-only feature for v1 — compiles to the same Jinja strings the
+  backend already accepts.
+- Blocks: `Text`, `Variable`, `If`, `For`, `Link`, `Image`, `Icon`, `Caption`,
+  `Group` (HTML span/group). Each block knows its serialized Jinja
+  representation.
+- Round-trip: variables, simple `{% if %}` / `{% for %}` blocks, and string
+  literals parse back to blocks; arbitrary Jinja stays in a "Raw" block that
+  the user can edit as text.
+- Variable picker reads `get_template_variables(provider_type, slot)`. This is
+  the same data already shown in the template-help panel.
+- Preview pane unchanged — reuses `services/sample_context.py` server
+  rendering.
+- Toggle in the template editor: **Visual / Code**.
+
+**Open questions.**
+
+- Round-tripping arbitrary Jinja is hard. v1: parseable subset → blocks,
+  anything else → single Raw block. Show a banner explaining.
+- Locale handling: same compiled Jinja, just authored per locale tab.
+- Do we want a marketplace of pre-built block compositions? Out of scope for
+  v1 — bundle import/export is a separate backlog item.
+
+---
+
+## Recommended Sequencing
+
+1. **Quiet Hours per Target** — small, isolated, immediate user value.
+2. **Immich Smart Actions** — incremental on existing pattern; ship one
+   action at a time (start with auto-favorite by person).
+3. **Home Assistant Provider** — multi-file, follows new-provider checklist;
+   biggest user-base expansion.
+4. **Block-Based Template Builder** — largest frontend lift; benefits from
+   the variable-doc work that the other features will exercise.
+
+Dependencies are loose — 1 and 2 are independent of 3 and 4. The block
+builder pairs nicely with Home Assistant because HA's rich context surfaces
+the value of an easier authoring UX.
+

+> (see [feature-backlog.md](feature-backlog.md)).
+> Last updated: 2026-05-13.
+
+## Decision: WebSocket subscription, not webhook
+
+We considered three ingest modes (webhook automation, WebSocket subscription,
+hybrid). The WebSocket route is chosen as the architectural foundation because
+the medium-term roadmap forces it anyway:
+
+| Phase | Capability | Needs API access? |
+| --- | --- | --- |
+| 1 | Subscribe to events, emit notifications | Read (event stream) |
+| 2 | Bot commands (`/state`, `/entities`, `/areas`) | Read (REST or WS get_states) |
+| 3 | Smart Actions (`light.turn_on`, scene activation) | Write (call_service) |
+
+A webhook-only Phase 1 would still need a REST client by Phase 2 and a write
+path by Phase 3 — net result is two client implementations + one event
+pipeline refactor. WebSocket consolidates all three phases on one connection.
+
+**Tradeoff (be honest):** WebSocket introduces a long-lived-connection pattern
+this codebase does not have yet. Reconnect logic, missed-events-on-restart
+gap, and a new shape on the `ServiceProvider` ABC are real costs. Phase 1 is
+**not** shippable in one short session — plan for a multi-session build.
+
+## Provider abstraction extension
+
+The current `ServiceProvider` ABC
+([packages/core/src/notify_bridge_core/providers/base.py](../../packages/core/src/notify_bridge_core/providers/base.py))
+is poll-oriented: every provider implements `poll(collection_ids, state) →
+(events, new_state)`. Webhook providers (Gitea, Planka, Webhook) satisfy this
+by no-op'ing `poll` and shoving events in via `api/webhooks.py` instead.
+
+Home Assistant fits neither cleanly. The plan:
+
+1. Add an **optional** `async subscribe(emit) → None` method on the base ABC.
+   Default implementation raises `NotImplementedError`. Polling providers do
+   not override it. The scheduler / lifecycle layer (currently `services/watcher.py`)
+   gains a "subscription manager" branch that, for any provider whose class
+   overrides `subscribe`, starts a long-lived task instead of registering
+   a polling job.
+2. `emit` is a callback `(event: ServiceEvent) → None` provided by the
+   subscription manager — it routes events to the dispatcher exactly like the
+   webhook handler does today. Keeping the dispatch path unchanged is the
+   point of this design.
+3. Reconnect lives **inside** `subscribe`: the method is expected to be a
+   `while not cancelled: try connect; on drop, sleep with backoff, retry`
+   loop. The manager cancels the task on shutdown via the cooperative cancel
+   token used elsewhere.
+
+This is a small, additive change to one ABC. No existing provider is
+modified.
+
+## Phase 1 — Subscribe + Dispatch (MVP)
+
+### Scope
+
+- Long-lived WebSocket connection to HA, authenticated with a long-lived
+  access token.
+- Subscribe to the event bus with optional `event_type` filter (defaults to
+  `state_changed`).
+- Translate HA events into `ServiceEvent` and dispatch via the existing
+  pipeline. Notifications go out exactly as they do today for any other
+  provider.
+- Filter UI: entity-id glob list, domain allowlist (e.g. `light.*`,
+  `binary_sensor.*`), event-type allowlist. **Hard-required** to avoid the HA
+  firehose drowning the bridge.
+- Connection test + entity listing via WS `get_states` (no REST client yet —
+  WS gives us both subscribe and read).
+
+### Out of scope for Phase 1
+
+- Bot commands → Phase 2.
+- Service calls → Phase 3.
+- Replay of events missed during disconnect (HA does not support this; we
+  document the gap and surface "reconnected after N seconds" in the event
+  log).
+- Webhook-style ingestion (path-embedded token webhook receiver). If a user
+  prefers webhooks, we add it later as a second ingestion mode on the same
+  provider — out of scope for v1.
+
+### Event types (v1)
+
+| HA event | ServiceEvent type | Notification slot |
+| --- | --- | --- |
+| `state_changed` | `ha_state_changed` | `message_state_changed` |
+| `automation_triggered` | `ha_automation_triggered` | `message_automation_triggered` |
+| `call_service` | `ha_service_called` | `message_service_called` |
+| (custom event types) | `ha_event_fired` | `message_event_fired` |
+
+Default tracking config enables `state_changed` only — the others are loud
+and opt-in.
+
+### Context variables exposed to templates
+
+Pulled directly from HA's `state_changed` payload, normalized:
+
+- `entity_id` — `light.kitchen`
+- `friendly_name` — `attributes.friendly_name` or fallback to `entity_id`
+- `domain` — derived from `entity_id` before the dot
+- `old_state` — `from_state.state`
+- `new_state` — `to_state.state`
+- `attributes` — dict of new-state attributes (raw)
+- `device_class` — `attributes.device_class` if present
+- `area` — `attributes.area_id` if present (best effort; only set if HA
+  exposes it via the area registry, which costs a `get_registry` WS call —
+  see "Open questions")
+- `last_changed`, `last_updated` — ISO timestamps
+- For non-`state_changed` events: `event_type`, `event_data` (full dict)
+

+
+### Frontend descriptor essentials
+
+```text
+type: "home_assistant"
+defaultName: "Home Assistant"
+icon: "home" (consider Lucide icon; HA logo if a custom asset exists)
+hasUrl: true            // base URL of HA (used to derive WS URL)
+configFields:
+  - url:                http(s)://homeassistant.local:8123
+  - access_token:       long-lived access token (required)
+  - allowed_event_types: comma-separated, defaults to "state_changed"
+eventFields: 4 checkboxes (state_changed, automation_triggered,
+                           call_service, event_fired)
+extraTrackingFields:
+  - entity_glob: tag input ("light.*", "binary_sensor.*_motion")
+  - domain_allowlist: tag input
+collectionMeta: { label: "Entities", icon: "..." }
+webhookBased: false     // we are NOT webhook based
+```
+
+WS URL is derived: `wss://{host}/api/websocket` (or `ws://` for plain http
+HA). Document this in the UI hint.
+
+### Auth model
+
+- **Long-lived access token** from HA (Profile → Long-Lived Access Tokens).
+- Stored encrypted at rest via the same path the other providers use for
+  secrets (the bridge already has a secret-encryption helper — verify the
+  exact module name during implementation).
+- WS auth handshake: connect → server sends `auth_required` → client sends
+  `{type: "auth", access_token: "..."}` → server replies `auth_ok` or
+  `auth_invalid`.
+
+### Risks / open questions (Phase 1)
+
+1. **Reconnect strategy.** Exponential backoff capped at 60s, jittered.
+   On reconnect, log a `connection_restored_after` event so the UI can
+   surface the gap. Document that HA does not support event replay.
+2. **Area registry.** Pulling `area_id` for entities requires a separate
+   `config/area_registry/list` WS call. Decision needed: fetch once on
+   connect and cache, refetch on `area_registry_updated` event, or skip
+   `area` from the context entirely in v1. Recommendation: fetch on
+   connect, refetch on `area_registry_updated`, skip if it fails (best-effort).
+3. **TLS verification for self-signed HA.** Homelab users often have
+   self-signed certs. Need a `verify_tls: bool` config field (default true)
+   and a clear warning when disabled. Same pattern as
+   `NOTIFY_BRIDGE_ALLOW_PRIVATE_URLS` for the SSRF case.
+4. **Backpressure.** HA's `state_changed` can fire hundreds of events per
+   minute in a busy install. The subscription manager must drop or coalesce
+   if the dispatcher backlog grows beyond a threshold. Cheapest cut: a
+   bounded `asyncio.Queue` between WS receiver and dispatch — `put_nowait`
+   with overflow counter visible in the event log.
+5. **Entity filter precedence.** Tracking-config has `collection_ids`
+   (entity_id list) and we want `entity_glob` + `domain_allowlist`. Decision:
+   if both `collection_ids` and globs are set, union them (any match passes).
+   Documented prominently in the tracker UI.
+6. **Library choice.** `hass-client` is a Python WS client maintained by the
+   HA community; alternative is rolling our own with `websockets`. The
+   latter is ~150 LOC and has no external dependency surface. Recommendation:
+   roll our own. Re-evaluate if Phase 3 needs registry-aware service calls.
+
+## Phase 2 — Bot Commands
+
+Adds Telegram bot commands for HA tracking configs.
+
+- `/status` — connection status, subscribed event count
+- `/entities <glob>` — list matching entities + current state
+- `/state <entity_id>` — full state + attributes for one entity
+- `/areas` — area registry summary
+- `/help`
+
+These use the existing WS connection (no new client) via WS commands
+`get_states`, `config/area_registry/list`. Template slots and command
+template configs follow the same pattern as Gitea/Planka — see
+[CLAUDE.md](../../CLAUDE.md) rule 7 / rule 11 for the full set of locations
+that must be updated.
+
+Out-of-scope for Phase 2: any command that mutates HA state.
+
+## Phase 3 — Smart Actions (Service Calls)
+
+A new action descriptor in the existing Smart Actions framework
+([packages/core/src/notify_bridge_core/providers/actions.py](../../packages/core/src/notify_bridge_core/providers/actions.py)).
+
+- Action type: `ha_call_service`
+- Rule: trigger event → service call (e.g. "on motion event in
+  `binary_sensor.front_door` → call `light.turn_on` on `light.porch`")
+- Executor uses the existing WS connection to send `call_service`.
+
+This phase is gated behind explicit per-target authorization in the UI — HA
+service calls can do anything the access token allows, including unlocking
+doors. Default state: **disabled**, with a clear consent flow when enabling.
+
+## Rough effort estimates
+
+These are rough — sub-task discovery during Phase 1 will refine them.
+
+| Phase | Estimate (focused work) |
+| --- | --- |
+| Phase 1 (subscribe + dispatch) | 2–3 sessions |
+| Phase 2 (bot commands) | 1 session |
+| Phase 3 (smart actions) | 1–2 sessions |
+
+## When to start
+
+Phase 1 work order, once you green-light it:
+
+1. ABC extension (`base.py`) + tests for the new `subscribe` shape on a fake
+   provider.
+2. WS client + parser + unit tests against recorded HA fixtures (no live HA
+   needed for these).
+3. Subscription manager in `services/watcher.py` — integration test with the
+   fake provider from step 1.
+4. Templates (en + ru), capabilities entry, validator whitelist.
+5. Server: seeds, sample context, template_configs entry.
+6. Frontend: descriptor, locale keys, i18n.
+7. End-to-end smoke test against a real HA instance (homelab).
+
+Backend restart cadence per the project rule: after **every** change in
+`packages/server/` or `packages/core/`.
+

+## Debug Issue
+
+Use the knowledge graph to systematically trace and debug issues.
+
+### Steps
+
+1. Use `semantic_search_nodes` to find code related to the issue.
+2. Use `query_graph` with `callers_of` and `callees_of` to trace call chains.
+3. Use `get_flow` to see full execution paths through suspected areas.
+4. Run `detect_changes` to check if recent changes caused the issue.
+5. Use `get_impact_radius` on suspected files to see what else is affected.
+
+### Tips
+
+- Check both callers and callees to understand the full context.
+- Look at affected flows to find the entry point that triggers the bug.
+- Recent changes are the most common source of new issues.
+
+## Token Efficiency Rules
+- ALWAYS start with `get_minimal_context(task="<your task>")` before any other graph tool.
+- Use `detail_level="minimal"` on all calls. Only escalate to "standard" when minimal is insufficient.
+- Target: complete any review/debug/refactor task in ≤5 tool calls and ≤800 total output tokens.

+
+## Review Changes
+
+Perform a thorough, risk-aware code review using the knowledge graph.
+
+### Steps
+
+1. Run `detect_changes` to get risk-scored change analysis.
+2. Run `get_affected_flows` to find impacted execution paths.
+3. For each high-risk function, run `query_graph` with pattern="tests_for" to check test coverage.
+4. Run `get_impact_radius` to understand the blast radius.
+5. For any untested changes, suggest specific test cases.
+
+### Output Format
+
+Provide findings grouped by risk level (high/medium/low) with:
+- What changed and why it matters
+- Test coverage status
+- Suggested improvements
+- Overall merge recommendation
+

+# Operations Guide
+
+This document covers running, monitoring, and recovering Notify Bridge in
+production. The intended audience is the operator on call when the
+notifications stop firing or when a release upgrade goes sideways.
+
+For developer-focused docs (architecture, conventions, project layout) see
+`CLAUDE.md` and the `.claude/docs/` directory.
+
+## Deployment overview
+
+Notify Bridge ships as a single Docker image. All state lives in a single
+data directory mounted at `/data`.
+
+### Required environment variables
+
+| Variable | Default | Notes |
+| --- | --- | --- |
+| `NOTIFY_BRIDGE_SECRET_KEY` | _(none)_ | **Required.** 32+ random bytes. The server refuses to boot with the default placeholder or any of the known dev literals. |
+| `NOTIFY_BRIDGE_CORS_ALLOWED_ORIGINS` | `http://localhost:5175` | Comma-separated list. `*` is rejected because credentials are enabled. |
+| `NOTIFY_BRIDGE_FORWARDED_ALLOW_IPS` | `127.0.0.1` | Trusted proxy IPs whose `X-Forwarded-For` / `X-Forwarded-Proto` headers are honored. Set to your reverse-proxy IP. |
+
+### Useful environment variables
+
+| Variable | Default | Notes |
+| --- | --- | --- |
+| `NOTIFY_BRIDGE_DATA_DIR` | `/data` | Where the SQLite DB, snapshots, and backups live. |
+| `NOTIFY_BRIDGE_DATABASE_URL` | _(derived from data_dir)_ | Override only if you want a non-default DB path. |
+| `NOTIFY_BRIDGE_DEBUG` | `false` | Verbose logging + SQL echo. Do not enable in production. |
+| `NOTIFY_BRIDGE_LOG_FORMAT` | `text` | Set to `json` for one JSON object per line — pipe to a log aggregator. |
+| `NOTIFY_BRIDGE_LOG_LEVEL` | `INFO` | Root logger level. |
+| `NOTIFY_BRIDGE_LOG_LEVELS` | _(empty)_ | Per-module overrides, e.g. `sqlalchemy.engine=WARNING,notify_bridge_core.notifications.telegram.client=DEBUG`. |
+| `NOTIFY_BRIDGE_EVENT_LOG_RETENTION_DAYS` | `30` | Days of `event_log` history kept by the daily cleanup job. `0` disables retention. |
+| `NOTIFY_BRIDGE_PRE_MIGRATE_SNAPSHOT_KEEP` | `5` | Number of pre-migration DB snapshots retained. `0` disables snapshotting. |
+| `NOTIFY_BRIDGE_METRICS_ENABLED` | `true` | Expose `/api/metrics` for Prometheus. Set to `false` if the API port crosses a trust boundary. |
+| `NOTIFY_BRIDGE_GRACEFUL_SHUTDOWN_SECONDS` | `60` | SIGTERM grace period before in-flight requests are killed. |
+| `NOTIFY_BRIDGE_SUPERVISED` | _(auto)_ | Force the supervised flag for `apply-restart`. Use `true` when running under systemd/PM2 outside Docker. |
+
+### Data directory layout
+
+```
+/data/
+  notify_bridge.db          # main SQLite DB (WAL mode)
+  notify_bridge.db-wal      # SQLite write-ahead log
+  notify_bridge.db-shm      # SQLite shared memory file
+  backups/
+    pre-migrate-*.db        # automatic pre-upgrade snapshots
+    backup-*.json           # scheduled / manual config backups
+  snapshots/                # legacy alias retained for older deployments
+  pending_restore.json      # staged restore (consumed at next boot)
+  applied_restores/         # archive of applied restore payloads
+```
+
+Always mount `/data` on a persistent volume. The WAL files MUST live on the
+same filesystem as the main DB — never split them across mounts.
+
+### Docker example
+
+See `docker-compose.yml` at the repo root for the canonical reference. The
+container runs read-only with `tmpfs` for `/tmp`, drops all capabilities,
+and limits memory/CPU. The healthcheck targets `/api/ready` (deep) — see
+the next section.
+
+## Healthchecks
+
+Two endpoints, used for different probe types.
+
+### `GET /api/health` — liveness, shallow
+
+Returns `200 OK` once the ASGI app has started. Does not touch the DB or
+the scheduler. Use this for liveness probes that should only restart the
+process if it stops responding entirely.
+
+```json
+{"status": "ok", "version": "0.8.0"}
+```
+
+### `GET /api/ready` — readiness, deep
+
+Verifies that each critical dependency is reachable:
+
+* **db** — `SELECT 1` against the SQLAlchemy engine, 2-second timeout.
+* **scheduler** — APScheduler `running` flag.
+* **ha** — Home Assistant subscription supervisor task. Reported as
+  `na` when no HA providers are configured, `ok` when at least one
+  supervisor is alive, `degraded` otherwise. **Informational only** —
+  HA degradation does not flip readiness off.
+
+Returns `503` when any required check (db, scheduler) fails.
+
+```json
+{
+  "ready": true,
+  "checks": {"db": "ok", "scheduler": "ok", "ha": "na"},
+  "errors": [],
+  "version": "0.8.0"
+}
+```
+
+### Kubernetes probe example
+
+```yaml
+livenessProbe:
+  httpGet:
+    path: /api/health
+    port: 8420
+  initialDelaySeconds: 10
+  periodSeconds: 30
+  timeoutSeconds: 5
+  failureThreshold: 3
+
+readinessProbe:
+  httpGet:
+    path: /api/ready
+    port: 8420
+  initialDelaySeconds: 15
+  periodSeconds: 15
+  timeoutSeconds: 5
+  failureThreshold: 2
+```
+
+The Docker compose file uses `/api/ready` as its healthcheck so the
+container is only reported healthy after migrations finish.
+
+## Metrics
+
+Notify Bridge exposes Prometheus metrics at `GET /api/metrics` in the
+standard text exposition format. **No authentication** — Prometheus
+scrapers do not authenticate. Disable via `NOTIFY_BRIDGE_METRICS_ENABLED=false`
+when the API port is reachable beyond the trust boundary.
+
+### Prometheus scrape example
+
+```yaml
+scrape_configs:
+  - job_name: notify-bridge
+    metrics_path: /api/metrics
+    static_configs:
+      - targets: ['notify-bridge.internal:8420']
+    scrape_interval: 30s
+```
+
+### Available metrics
+
+| Metric | Type | Labels | Meaning |
+| --- | --- | --- | --- |
+| `notify_bridge_deferred_pending` | Gauge | _(none)_ | Pending rows in `deferred_dispatch`. Refreshed on each scrape. A persistent non-zero value usually means a tracker target is in extended quiet hours. |
+| `notify_bridge_event_log_total` | Counter | `status`, `event_type` | Events written to `event_log`. `status` is the dispatch outcome (`dispatched`, `dropped`, `deferred`, etc.). |
+| `notify_bridge_dispatch_duration_seconds` | Histogram | `channel` | Wall-clock duration of one outbound dispatch (Telegram, Discord, email, …). Useful for latency alerts. |
+| `notify_bridge_provider_poll_failures_total` | Counter | `provider_type` | Polling provider tick failures (Immich poll error, Gitea API down, …). Compare against expected scan interval to compute failure rate. |
+| `notify_bridge_target_send_failures_total` | Counter | `target_type`, `status_code` | Failed sends to a notification channel. `status_code` is the HTTP status (or `0` when no HTTP response was received). |
+
+The metrics module never imports `prometheus_client` outside `api/metrics.py`.
+Other modules record events through the `metrics` singleton — see that
+module's docstring before adding new collectors.
+
+## Backups
+
+Notify Bridge produces three different kinds of backup files. Know which
+one you are looking at before restoring.
+
+| Kind | Location | Format | Trigger |
+| --- | --- | --- | --- |
+| Config backup | `data/backups/backup-*.json` | JSON (BackupFile schema) | Manual via `/api/backup/files` POST or scheduled job |
+| Pre-migration snapshot | `data/backups/pre-migrate-*.db` | SQLite DB file | Automatic on every boot before migrations |
+| Pending restore | `data/pending_restore.json` | JSON | Staged via `/api/backup/prepare-restore`, consumed at next restart |
+
+Config backups capture user configuration (providers, trackers, targets,
+templates, …). They do **not** include `event_log`, `deferred_dispatch`,
+or any other operational table. Pre-migration snapshots are full DB
+copies and contain everything.
+
+### Manual backup
+
+The admin UI has a one-click button under Settings → Backup. Equivalent
+HTTP call:
+
+```bash
+curl -fsS -X POST \
+  -H "Authorization: Bearer $ADMIN_JWT" \
+  "https://notify-bridge.example.com/api/backup/files?secrets_mode=exclude"
+```
+
+The download endpoint produces a downloadable JSON envelope with no
+secrets unless `secrets_mode=include` is passed:
+
+```bash
+curl -fsS -X GET \
+  -H "Authorization: Bearer $ADMIN_JWT" \
+  -OJ "https://notify-bridge.example.com/api/backup/export?secrets_mode=exclude"
+```
+
+### Scheduled backup
+
+Configure under Settings → Backup or via `PUT /api/backup/scheduled` with:
+
+```json
+{
+  "backup_scheduled_enabled": "true",
+  "backup_scheduled_interval_hours": "24",
+  "backup_secrets_mode": "exclude",
+  "backup_retention_count": "5"
+}
+```
+
+Saved files land in `data/backups/`; retention prunes the oldest files
+beyond `backup_retention_count`. Backups can be downloaded individually:
+
+```bash
+curl -fsS -X GET \
+  -H "Authorization: Bearer $ADMIN_JWT" \
+  "https://notify-bridge.example.com/api/backup/files/backup-2026-05-16T12-00-00.json" \
+  -o backup-latest.json
+```
+
+### Cron snippet for off-host backup
+
+```bash
+# /etc/cron.d/notify-bridge-backup
+0 3 * * * www-data \
+  curl -fsS -X POST \
+    -H "Authorization: Bearer $(cat /etc/notify-bridge/admin.token)" \
+    "https://notify-bridge.example.com/api/backup/files?secrets_mode=exclude" \
+    -o /var/backups/notify-bridge/backup-$(date +\%F).json
+```
+
+### Restore procedure
+
+Restoring REPLACES configuration. Always export the current state first.
+
+```bash
+# 1. Stage the backup file (validates and writes to data/pending_restore.json)
+curl -fsS -X POST \
+  -H "Authorization: Bearer $ADMIN_JWT" \
+  -F "file=@backup-2026-05-16T12-00-00.json" \
+  "https://notify-bridge.example.com/api/backup/prepare-restore?conflict_mode=overwrite"
+
+# 2. Trigger graceful restart so startup applies the staged restore.
+#    Same-origin Origin/Referer is enforced — call from the admin UI when
+#    possible, or from the same host. Requires the supervisor to respawn
+#    the process (Docker restart policy, systemd, PM2, etc.).
+curl -fsS -X POST \
+  -H "Origin: https://notify-bridge.example.com" \
+  -H "Referer: https://notify-bridge.example.com/settings/backup" \
+  -H "Authorization: Bearer $ADMIN_JWT" \
+  "https://notify-bridge.example.com/api/backup/apply-restart"
+```
+
+If the process is **not** supervised, `/api/backup/apply-restart` returns
+`409`. Restart the backend manually after staging — startup applies the
+pending restore on the next boot.
+
+To cancel a staged restore before applying:
+
+```bash
+curl -fsS -X DELETE \
+  -H "Authorization: Bearer $ADMIN_JWT" \
+  "https://notify-bridge.example.com/api/backup/pending-restore"
+```
+
+### Recovery from a corrupted DB
+
+If migrations crash on boot or the DB file is unreadable, roll back to a
+pre-migration snapshot:
+
+```bash
+# Stop the backend, then
+cd /var/lib/docker/volumes/notify-bridge-data/_data
+ls -1t backups/pre-migrate-*.db | head -5      # pick the snapshot
+
+cp notify_bridge.db notify_bridge.db.broken    # keep the broken DB for forensics
+cp backups/pre-migrate-2026-05-16T11-58-30.db notify_bridge.db
+rm -f notify_bridge.db-wal notify_bridge.db-shm   # WAL belongs to the broken file
+```
+
+Restart the container. The startup snapshot will run again and capture
+the rolled-back state, so you have a clean recovery point if the next
+boot needs another rollback.
+
+## Logs
+
+* Output goes to **stderr only**. The Docker log driver captures it.
+* Set `NOTIFY_BRIDGE_LOG_FORMAT=json` for line-delimited JSON suitable
+  for Loki, ELK, or CloudWatch.
+* Secret values (bot tokens, API keys, passwords) are masked at the log
+  formatter level — see `notify_bridge_server.logging_setup`.
+* No file rotation is built in. Use the Docker JSON log driver's
+  `max-size`/`max-file` options or send logs to your aggregator.
+
+```yaml
+# docker-compose.yml snippet
+logging:
+  driver: json-file
+  options:
+    max-size: "10m"
+    max-file: "5"
+```
+
+## Common operational scenarios
+
+### "Notifications stopped firing"
+
+1. Hit `/api/ready`. If `scheduler` is `fail`, restart the backend; the
+   scheduler died in a way it cannot recover from.
+2. Check `notify_bridge_deferred_pending`. A non-zero value during quiet
+   hours is normal; a value that grows monotonically across days is a
+   bug — inspect the `deferred_dispatch` table.
+3. Inspect the most recent `event_log` rows in the admin Events page or:
+
+   ```sql
+   SELECT created_at, event_type, dispatch_status, details
+   FROM event_log
+   ORDER BY created_at DESC LIMIT 50;
+   ```
+
+   Look for a `dispatch_status` other than `dispatched`.
+4. If a single tracker is silent, verify the provider's last poll status
+   in the admin UI (Providers page) — `notify_bridge_provider_poll_failures_total`
+   tells you which provider type is failing.
+5. If you've configured a `bridge_self` tracker but never received a
+   self-monitoring alert when something failed, see the next section —
+   `bridge_self` failures are deliberately log-only to prevent recursion.
+
+### Bridge self-monitoring is log-only on its own failures
+
+The built-in `bridge_self` provider emits notifications when polls,
+dispatches, or target sends fail. To prevent infinite-recursion (a
+`bridge_self` notification failing → triggering another `bridge_self`
+notification → ...), failures of `bridge_self` events themselves are
+**not** counted toward target-failure thresholds and are logged only.
+
+If your `bridge_self` notifications stop arriving, it means the
+notification target you wired them to is itself failing. Grep stderr for:
+
+```text
+bridge_self target-failure emission failed
+emit_bridge_self_event failed
+```
+
+The fix is always at the target layer (Telegram bot blocked, Matrix
+homeserver down, SMTP credentials rotated). The bridge cannot tell you
+about its own outbound failure — that's what the operator's external
+monitoring (Prometheus alert on `notify_bridge_target_send_failures_total`)
+is for.
+
+### "Webhook returns 500"
+
+Inspect the `webhook_payload_log` table for the matching request:
+
+```sql
+SELECT received_at, status_code, error_message, payload_excerpt
+FROM webhook_payload_log
+ORDER BY received_at DESC LIMIT 20;
+```
+
+Common causes: payload schema change in the source service, a tracker
+referencing a deleted provider, a Jinja template that errors out (look
+for `template render failed` in logs).
+
+### "Telegram bot rate-limited (429)"
+
+The Telegram client implements exponential backoff with jitter on
+`Retry-After`. No operator action is required for transient throttling.
+If the rate-limit persists, check:
+
+* The bot is being driven by multiple Notify Bridge instances pointing
+  at the same chat (split-brain — only one instance should own a bot).
+* A template is producing very large messages (Telegram limits message
+  size to 4096 chars). Look for `MessageTooLong` in the logs.
+
+### "DB lock contention"
+
+SQLite WAL mode and `busy_timeout=10000` make this rare. If you see
+`SQLITE_BUSY` in logs:
+
+* Check for long-running transactions (most often a stuck migration).
+* Confirm the WAL files are on the same filesystem as the main DB —
+  splitting them across mounts is a known cause.
+* Run `sqlite3 notify_bridge.db "PRAGMA wal_checkpoint(TRUNCATE);"` to
+  flush the WAL. Safe to run while the backend is up.
+
+## Upgrades
+
+1. Pre-migration snapshot is taken automatically before any migration
+   runs. The latest five snapshots are retained by default.
+2. Migrations are idempotent — re-running an upgrade is safe.
+3. If a migration fails, the snapshot from step 1 is the recovery point.
+   See "Recovery from a corrupted DB" above.
+4. Always test major version upgrades in staging first. The upgrade flow
+   is the same in staging: pull the new image, restart the container.
+
+The release tag stream lives at the project Gitea / GitHub releases page.
+Release notes are written to `RELEASE_NOTES.md` for the upcoming version
+and copied into the Gitea release body by the `release.yml` workflow.

+## ⚠️ Breaking Changes
+
+- **Telegram webhook secret is now mandatory.** `NOTIFY_BRIDGE_TELEGRAM_WEBHOOK_SECRET` must be set when running Telegram bots in webhook mode — the inbound endpoint returns 401 without it. Polling-mode bots are unaffected ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Generic webhooks with `auth_mode="none"` require explicit opt-in.** Existing unauthenticated webhook providers must set `acknowledge_unauthenticated=true` in their config or they will be rejected. Generic webhook ingest is also rate-limited to 60 requests/min per source IP ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Every user now gets a `bridge_self` provider auto-seeded.** It is internal-only and excluded from the "create provider" wizard, but appears in the provider list. Wire it to a Telegram/Email/Matrix target to receive bridge health alerts ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
 
 ## User-facing changes
 
 ### Features
 
-- **Quiet hours now defer notifications instead of dropping them.** Events that arrive during a tracker's quiet window are stored on disk and re-fired at the window end. Asset events for the same `(link, event_type, collection)` coalesce so a flurry of adds/removes during the night collapses into a single morning notification ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- **Home Assistant provider.** New service provider that subscribes to a Home Assistant instance over WebSocket (long-lived connection with auth handshake, exponential-backoff reconnect, area-registry enrichment) and emits 4 event types: `state_changed`, `automation_triggered`, `call_service`, `event_fired`. Trackers support entity-glob, domain-allowlist, and exact-id filters via the new `TagInput` UI control ([22127e2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/22127e2))
-- **Upstream release check.** New "Release Cassette" in Settings polls a configurable Gitea or GitHub repo on a schedule and surfaces the latest tag in the UI so you know when a newer Notify Bridge is available. Pre-release filtering and interval are operator-configurable; the install ships pointed at this repo's own upstream ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- **Home Assistant bot commands.** `/status`, `/entities [glob]`, `/state <entity_id>`, `/areas` — query your HA instance from chat. Multi-command WS sessions reuse a single handshake; sensitive attributes (camera access tokens, entity pictures, etc.) are blocklisted and `/state` output is capped at 30 attributes to stay within Telegram message limits ([22127e2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/22127e2))
-- **Frontend polish across the board.** New `MetaStrip` component, expanded `EventDetailModal`, and i18n additions land alongside cohesive Aurora-glass styling tweaks on most management pages — providers, targets, bots, trackers, command and notification templates, users, actions, layout, and dashboard ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- **Bridge self-monitoring (`bridge_self` provider).** A new internal provider type emits health events from the bridge itself: `bridge_self_poll_failures` (consecutive tracker poll failures), `bridge_self_deferred_backlog` (pending defers above threshold), `bridge_self_target_failures` (consecutive 5xx/network failures per target). Per-user thresholds default to 3 / 100 / 5 and are configurable. Self-loop guard ensures bridge_self failures never count toward target-failure thresholds ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **bridge_self bot commands.** `/status`, `/thresholds`, `/reset`, `/health` let operators inspect bridge health and reset counters from chat. Includes Jinja2 templates for both locales ([8651767](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/8651767))
+- **On-watch stats scope selector.** New icon toggle on the "On watch" provider deck switches between page-scoped stats (legacy) and full-corpus stats that aggregate across every event matching the active filters ([dec0839](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/dec0839))
 
-### Documentation
+### Bug Fixes
 
-- README rewritten to cover every supported provider, target type, bot command, and smart action — including the deploy / env-var matrix ([bb5afcc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/bb5afcc), [4335036](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/4335036))
+- **Immich periodic summary now honors `periodic_interval_days`.** A configured 3-day interval was firing every day because the dispatch path never consulted the interval or start date. The scheduler now gates on `(today - start_date).days % interval == 0` and logs `interval_not_due` skips so operators can distinguish suppressed-by-interval from other skip causes ([90f958b](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/90f958b))
+- **Planka webhook crash fixed.** The handler had a `NameError` on every call when reading the request body — webhook ingest from Planka now works ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **HA quiet-hours dropped events.** `ha_state_changed`, `automation_triggered`, `service_called`, and `event_fired` were missing from the deferrable set and were silently dropped during quiet windows. They now defer like every other event type ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Notifier no longer cancels peer sends on a single failure.** Switched the per-receiver fan-out to `asyncio.gather(return_exceptions=True)`; one bad chat won't cancel sends to the rest ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Quiet-hours gate now respects event-type-disabled.** When a tracker has the event type disabled, that wins over the deferral path — events are dropped, not stored to be drained later ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **NUT first poll seeds silently.** No more spurious `ups_on_battery` notification on the very first poll after adding a NUT provider ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **HA disconnect/reconnect now logged.** Status changes write `ha_status_*` rows to the EventLog so operators can see WS supervisor health in the UI ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+
+### Performance
+
+- **Jinja2 template compilation cached** with `lru_cache(maxsize=512)` — repeated renders of the same template no longer reparse the source ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Per-locale render cache in `NotificationDispatcher`** skips re-rendering identical content for receivers sharing a locale ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Tracker list cached per `provider_id`** with a 5s TTL plus explicit invalidation on tracker CRUD — relieves the HA chat-bus rate-query pressure ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Nav-counts collapsed from 16 round-trips to a single `UNION ALL`** ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **HA event_log skips empty events** — `assets_added`/`assets_removed` events with empty payloads are no longer persisted ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+
+### Security
+
+- **DNS-rebinding SSRF protection.** `PinnedResolver` is now wired into the shared aiohttp session — outbound URL validation pins the resolved IP for the lifetime of the request ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Mass-assignment guards** added on Action create/update; cron expressions with sub-minute granularity are rejected ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Backup import hardening.** JSON depth capped at 10, node count at 100k; `_sanitize_config` now extends to all JSON-typed fields on import ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Telegram `_safe_get` walks redirects manually** with SSRF revalidation at every hop ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Bcrypt 72-byte password length cap** with a clear `422` response (was silently truncating before) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Webhook payload body redaction.** Sensitive substring set extended with `oauth`, `client_secret`, `webhook_secret`, `csrf` in both header filter and template-extras filter ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+
+### Operations
+
+- **Deep healthcheck at `/api/ready`** — checks DB `SELECT 1`, scheduler running, HA supervisor presence; returns `{ready, checks, errors, version}` ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Prometheus metrics at `/api/metrics`** — `deferred_pending`, `event_log_total`, `dispatch_duration`, `poll_failures`, `send_failures` ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **New `OPERATIONS.md`** covering deploy, healthchecks, metrics, backup/restore procedures, log handling, common scenarios, and upgrade flow ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))

 ### Architecture
 
-- New `deferred_dispatch` table with two migrations: an `ON DELETE SET NULL` FK rebuild on `event_log_id` (so the daily event-log retention sweep no longer deadlocks against pending defers), and a partial unique index on `(link_id, collection_id, event_type) WHERE status='pending'` to make coalescing race-safe under SQLite's serializable writes ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- **Shared dispatch pipeline.** Extracted webhook ingest's event-log + deferred-dispatch + quiet-hours code path from `api/webhooks.py` into `services/event_dispatch.py` so HA subscription and webhook ingest now share the same pipeline ([22127e2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/22127e2))
-- Drain scheduler with three layers: a one-shot APScheduler `date` job per window-end (idempotent, minute-bucketed), a 5-minute periodic catch-up scan as safety net for misfire-grace overflow and process-restart gaps, and `load_pending_drain_jobs` to re-arm scheduled drains on boot ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- **`ServiceProvider` ABC gains optional `subscribe()`** for push-style providers; `HomeAssistantServiceProvider` uses it via a per-provider supervisor task started in the FastAPI lifespan ([22127e2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/22127e2))
-- Release-check provider abstraction (`packages/core/.../release/`) with Gitea and GitHub adapters, SSRF-safe outbound URL validation, a registry/factory, and a server-side scheduler probe with cached state and on-settings-change cache invalidation ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- **Provider construction switched from if/elif ladder to factory registry** ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
-- Version resolution helper (`packages/server/.../version.py`) that returns the max of installed-package metadata vs source `pyproject.toml` — fixes the long-running editable-install bug where bumping the version without reinstalling kept the old number visible in the UI ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- **Provider credential resolution unified** across all 5 dispatch sites ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **`NotificationDispatcher` hoisted out of the per-tracker loop** ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+
+### Database
+
+- **New UNIQUE indexes:** `service_provider.webhook_token`, `telegram_bot.webhook_path_id`, partial UNIQUE on `telegram_bot.bot_id`, `telegram_chat(bot_id, chat_id)`, `notification_tracker_target` unique link, partial UNIQUE on `bridge_self` provider per user ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Composite `ix_event_log_user_event_type_created` index** ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **`save_chat_from_webhook` switched to `ON CONFLICT DO UPDATE`** (was racy under concurrent webhook delivery) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **`ondelete=CASCADE` on user-id FKs** (model annotation; app-side cascade delete added for existing data) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **`delete_notification_tracker` converted from N+1 to bulk DELETE/UPDATE** ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Module-level `asyncio.Lock` replaced with lazy `_get_lock()` pattern** (avoids cross-event-loop binding) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **VACUUM INTO snapshot now `PRAGMA integrity_check`-verified** before being returned ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Batched `receivers/chats/bots` in `load_link_data`** (was per-target N+1) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **`flag_modified` on JSON column reassignments** in deferred_dispatch ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+
+### Frontend
+
+- **76 `catch (err: any)` sites converted to `errMsg(err)` helper** ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **`globalProviderFilter` made a pure getter**; reconciliation moved to a one-time `$effect` in `+layout` ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Provider-filter binding simplified** — paired `$effect`s and the `_syncingFilter` flag removed; now a one-way derived value ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **`entity-cache` got a separate `_refreshing` flag** for background re-fetches so loading spinners don't appear on revalidation ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **`api.ts` 401 handling rewritten:** `AuthRedirectError` class + dedup `_redirecting` flag, `goto()` instead of `window.location.href` ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Accessibility:** `aria-expanded` on mobile More menu, `role=switch` + `aria-checked` on Telegram bot toggles ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Provider-specific hardcoding removed:** Immich-only block extracted to descriptor `featureDiscoveryHint` ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **5 `svelte-check` null-narrowing errors fixed** in `EventDetailModal` ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **New `TagInput` component** for free-text glob/domain lists; new toggle `ConfigField` type for HA descriptor ([22127e2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/22127e2))
+
+### CI/Build
+
+- **CI pytest gate added** to `.gitea/workflows/build.yml` and `release.yml` (wheel-built install to dodge editable-install slowness on the hosted runner) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
 
 ### Tests
 
-- New test suites: `test_deferred_dispatch.py` (drain + coalescing + retention interaction), `test_release_provider.py` (Gitea and GitHub adapter parsing and error paths), and `test_release_service.py` (scheduler-level caching and settings invalidation) ([ba199f2](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/ba199f2))
+- **New test suites:** `test_bridge_self` (11), `test_gitea_parser` (9), `test_planka_parser` (6), `test_immich_change_detector` (6), `test_backup_roundtrip` (1) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+
+### Other
+
+- **`command_sync` snapshot+expunge bot before exiting `AsyncSession`** (was raising on detached-instance access) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **HA `asyncio.shield` now drains inner task on cancellation** (was leaking tasks on supervisor restart) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **APScheduler drain job ID resolution upgraded to seconds** (was minute-bucketed; collisions possible) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
+- **Webhook payload rollback failures now logged** (were swallowed) ([10d30fc](https://git.dolgolyov-family.by/alexei.dolgolyov/notify-bridge/commit/10d30fc))
