fix: use host bind mount for repos so tool instances can access workspace files

Replace named Docker volume (repo_data) with bind mount (/data/repos) in both
development and production compose files. The named volume trapped repo files
inside the API container; tool instances started via Docker socket on the host
could not see them, causing /workspace to mount as an empty directory.

Also fix 6 pre-existing test failures in test_tool_instances_legacy.py caused
by get_container_id/get_container_name moving to docker.py and new helpers
(_ensure_web_bind_address, _ensure_container_name_in_compose) being added.

- docker-compose.yml: repo_data:/data/repos -> /data/repos:/data/repos
- docker-compose.traefik.yml: same change + remove repo_data volume decl
- tests: update patch targets and add missing mock parameters

Quality gates: pytest test_tool_instances_legacy.py (10 passed)

+# PR-2 Apply Report: Backend Integration for Notification Center
+
+## Status: COMPLETE
+
+All 5 tasks for PR-2 (NC-PR2-001 through NC-PR2-005) have been implemented, tested, and validated.
+
+## What Was Implemented
+
+### NC-PR2-001: Wire lifecycle_hooks.py to NotificationService
+
+**File:** `apps/api/src/services/lifecycle_hooks.py`
+
+- Imported `notification_service` singleton from `src.services.notification_service`
+- Added `_derive_title(event_type)` helper mapping lifecycle events to human-readable titles:
+  - `instance.created` → "Container created"
+  - `instance.started` → "Container started"
+  - `instance.stopped` → "Container stopped"
+  - `instance.restarted` → "Container restarted"
+  - `instance.deleted` → "Container deleted"
+  - `instance.error` → "Container error"
+- After `event_bus.publish(...)`, calls `notification_service.create_notification(...)` with:
+  - `user_id = instance.owner_id`
+  - `category = "instance"`
+  - `severity = "error"` for `instance.error`, `"info"` for all others
+  - `source_type = "tool_instances"`, `source_id = instance.id`
+- Wrapped in `try/except`; logs failure with `correlation_id` and continues
+- Event bus publish and audit row insert are unaffected by notification failure
+
+### NC-PR2-002: Wire health_monitor.py to NotificationService
+
+**File:** `apps/api/src/services/health_monitor.py`
+
+- Imported `notification_service` singleton
+- After `self._event_bus.publish(event_type, payload)`, calls `notification_service.create_notification(...)` with:
+  - `user_id = instance.owner_id`
+  - `category = "instance"` for `new_status == "error"`
+  - `category = "health"` for `instance.health_changed`
+  - `severity` mapped:
+    - `"error"` for crash
+    - `"warning"` for unhealthy
+    - `"info"` for recovery (running)
+  - `title` mapped:
+    - "Container failed" for error
+    - "Container unhealthy" for unhealthy
+    - "Container recovered" for running
+- Wrapped in `try/except`; logs failure with `correlation_id` and continues
+- Original event bus publish and health check insert are unaffected
+
+### NC-PR2-003: Extend UserConfig schema for notification preferences
+
+**File:** `apps/api/src/api/user_config.py`
+
+- Added `notification_mute_categories: list[str] | None = None` to `UserConfigResponse`
+- Added `notification_toast_level: str | None = None` to `UserConfigResponse`
+- Added the same fields to `UserConfigUpdate`
+- Existing config keys are unaffected; new fields are optional with `None` defaults
+
+### NC-PR2-004: Event producer integration tests (RED)
+
+**File:** `apps/api/tests/integration/test_notifications_lifecycle.py` *(new)*
+
+6 integration tests covering:
+
+1. `test_lifecycle_event_creates_notification` — lifecycle hook `instance.started` creates `severity="info"` notification for owner
+2. `test_health_monitor_error_creates_notification` — simulated crash creates `severity="error"` notification for owner
+3. `test_notification_failure_does_not_block_event_pipeline` — mocked `create_notification` raising `RuntimeError`; event still published, no exception escapes
+4. `test_notification_ownership_matches_instance_owner` — notification `user_id` equals `instance.owner_id`, not the API caller
+5. `test_lifecycle_error_creates_error_notification` — `instance.error` maps to `severity="error"`, title="Container error"
+6. `test_health_monitor_unhealthy_creates_warning_notification` — tunnel failure creating `severity="warning"`, category="health"
+
+### NC-PR2-005: Verify producer tests and clean up (GREEN / REFACTOR)
+
+- All 6 new integration tests pass
+- 13 unit tests for `NotificationService` pass (no regressions)
+- 10 integration tests for notifications API pass (no regressions)
+- 6 existing health monitor unit tests pass (no regressions)
+- 6 existing event integration tests pass (no regressions)
+- `ruff check` passes on all modified files
+
+## TDD Cycle Evidence
+
+| Cycle | Task | Test File | RED | GREEN | Evidence |
+|-------|------|-----------|-----|-------|----------|
+| 1 | NC-PR2-004 (producer flow) | `tests/integration/test_notifications_lifecycle.py` | 4 tests written against unwired producers | Wired `lifecycle_hooks.py` and `health_monitor.py` | 4 passed |
+| 2 | NC-PR2-004 (severity mapping) | `tests/integration/test_notifications_lifecycle.py` | Added error + warning severity tests | Already green from implementation | 6 passed |
+| 3 | NC-PR2-003 (UserConfig schema) | `src/api/user_config.py` | Schema extended with new optional fields | PATCH/GET endpoints validate correctly | Verified manually |
+| 4 | NC-PR2-005 (REFACTOR) | All files | — | ruff clean, no regressions across 41 related tests | All pass |
+
+## Changed Files
+
+1. `apps/api/src/services/lifecycle_hooks.py` — Wired `NotificationService` after event bus publish
+2. `apps/api/src/services/health_monitor.py` — Wired `NotificationService` after state change event publish
+3. `apps/api/src/api/user_config.py` — Added `notification_mute_categories` and `notification_toast_level` to Pydantic schemas
+4. `apps/api/tests/integration/test_notifications_lifecycle.py` *(new)* — 6 integration tests for event-to-notification flow

+# Exit: 0 — All checks passed
+```
+
+## Deviations from Design
+
+None. All mappings and behaviors match the design spec (section 1.3) and task requirements exactly.
+
+## Surprises / Decisions
+
+1. **Health monitor `test_health_monitor_unhealthy_creates_warning_notification` required `public_url`:** The health monitor only checks tunnel health when `instance.public_url` is truthy. Without setting it on the test fixture instance, `_derive_status` returned `"running"` instead of `"unhealthy"`, which created an `"info"` notification. Fixed by setting `test_instance.public_url` in the test before calling `_check_instance`.
+
+2. **Patch target for failure test:** The `test_notification_failure_does_not_block_event_pipeline` patches `src.services.lifecycle_hooks.notification_service.create_notification`. This only works because `lifecycle_hooks.py` imports `notification_service` at module level, making the attribute resolvable by `unittest.mock.patch`.
+
+3. **No schema migration needed for UserConfig:** Preferences are stored in the existing JSON `config` blob, consistent with the existing pattern (theme, editor, git identity). No Alembic migration required.
+
+## Risks
+
+- **None:** All changes are additive. Event producers use `try/except` so notification failures cannot block the event pipeline. No existing test regressions introduced.
+
+## PR Boundary
+
+This PR covers PR-2 only (NC-PR2-001 through NC-PR2-005). PR-3 (frontend core) and PR-4 (toast coordination) are out of scope.

+# PR-3 Apply Report: Frontend Core for Notification Center
+
+## Status: COMPLETE
+
+All 9 tasks for PR-3 (NC-PR3-001 through NC-PR3-009) have been implemented, tested, and validated.
+
+## What Was Implemented
+
+### NC-PR3-001: Add bell icon to icon registry
+- Added `"bell"` to `IconName` union in `apps/web/src/utils/icons.ts`
+- Added `Bell` import from `@phosphor-icons/react` and mapped it in `iconRegistry`
+- Added `Bell` import and mapping in `apps/web/src/components/icon.tsx`
+
+### NC-PR3-002/003: NotificationProvider + useNotifications hook
+- **API client** (`apps/web/src/api/notifications.ts`): Typed wrappers for `GET /notifications`, `GET /notifications/unread`, `PATCH /{id}/read`, `POST /mark-all-read`, `DELETE /{id}`
+- **NotificationProvider** (`apps/web/src/state/notifications.tsx`):
+  - Maintains `notifications[]`, `unreadCount`, `isLoading`, `error`, `isDropdownOpen`
+  - Polls unread count every 15s, list every 30s (paused when dropdown open)
+  - Pauses all polling on `document.hidden`, resumes on visible
+  - Stops polling on 401
+  - Optimistic updates for `markRead`, `markAllRead`, `dismiss` with revert on failure
+- **useNotifications** (`apps/web/src/hooks/use-notifications.ts`): Thin context consumer hook
+
+### NC-PR3-004/005: NotificationCenter + NotificationItem components
+- **NotificationItem** (`apps/web/src/components/notification-item.tsx`):
+  - Displays severity icon (mapped from `severity` to existing Phosphor icons)
+  - Shows `title` and relative timestamp via `formatRelativeTime`
+  - Unread rows: `.notification-item--unread` (accent left border, tinted background, bolder)
+  - Read rows: `.notification-item--read` (reduced opacity)
+  - "Mark read" and "Dismiss" action buttons with accessible labels
+- **NotificationCenter** (`apps/web/src/components/notification-center.tsx`):
+  - Bell icon button with `aria-label="Notifications"`
+  - Red badge with unread count, capped at "99+"
+  - Dropdown panel with `role="dialog"`, opens on click, closes on outside-click or Escape
+  - Scrollable list of `NotificationItem` components
+  - Empty state: "No notifications"
+  - Footer "Mark all as read" button
+  - Calls `refreshList()` immediately on open

+## Deviations from Design
+
+1. **Polling interval race condition fix:** The dropdown `useEffect` was setting the list poll interval before the initial-start `useEffect` called `startPolling` in React Strict Mode, causing the initial list fetch to be skipped. Fixed by requiring `unreadIntervalRef.current` to be truthy before the dropdown effect resumes list polling, ensuring `startPolling` always owns the initial fetch.
+2. **Relative time formatter:** Added a lightweight custom `formatRelativeTime` utility (`apps/web/src/utils/time.ts`) rather than installing a date library, per the constraint not to add npm packages.
+
+## Surprises / Decisions
+
+1. **React Strict Mode interval race:** The order of effect execution in Strict Mode caused `listIntervalRef` to be populated before `startPolling` checked it, suppressing the initial list fetch. Adding `&& unreadIntervalRef.current` to the dropdown resume branch fixed this.
+2. **No npm packages installed:** All work used existing dependencies. Custom utility for relative time instead of `date-fns`.
+3. **`toBeInTheDocument` type warnings:** Testing-library jest-dom matchers are not automatically typed in `.test.tsx` files in this project setup. Tests pass at runtime; TypeScript warnings are cosmetic.

+# PR-4 Apply Report: Toast Coordination for Notification Center
+
+## Status: COMPLETE
+
+All 4 tasks for PR-4 (NC-PR4-001 through NC-PR4-004) have been implemented, tested, and validated.
+
+## What Was Implemented
+
+### NC-PR4-001: Update EventToastBridge with Preference Checks
+**File:** `apps/web/src/components/event-toast-bridge.tsx`
+- Reads `userConfig.notification_toast_level` and `userConfig.notification_mute_categories`
+- Preference hierarchy applied before showing toast:
+  1. Muted category → suppress
+  2. Toast level "none" → suppress all
+  3. Toast level "errors" + severity != "error" → suppress
+  4. Otherwise → show toast
+- Gracefully handles missing/null userConfig (defaults to "all", no muted categories)
+
+### NC-PR4-002: Extend toast-rules.ts with Category/Severity Mapping
+**File:** `apps/web/src/components/toast-rules.ts`
+- Added `mapEventToCategory(event)` — maps event types to categories:
+  - `instance.*` → "instance"
+  - `health.*` → "health"
+  - default → "system"
+- Added `mapEventToSeverity(event)` — maps event types to severity:
+  - `instance.error` → "error"
+  - `health.error` → "error"
+  - `health.unhealthy` → "warning"
+  - `health.recovered` → "success"
+  - others → "info"
+- Added `shouldShowToast(event, config)` — combines mapping with preference checks
+
+### NC-PR4-003: Notification Preference Controls in Settings Page
+**File:** `apps/web/src/pages/settings.tsx`
+- Added "Notification Preferences" section with:
+  - Toast level dropdown: "All notifications" / "Errors only" / "None"
+  - Mute categories checkboxes: "Instance events" / "Health events" / "System events"
+- Preferences loaded from UserConfig API
+- Changes saved via PATCH /user-config
+- Visual feedback on save
+
+**File:** `apps/web/src/api/settings.ts`
+- Extended settings API types with notification preference fields
+- Added `notification_toast_level` and `notification_mute_categories` to request/response types
+
+### NC-PR4-004: Toast Bridge Tests
+**File:** `apps/web/src/components/event-toast-bridge.test.tsx` *(new)*
+- 6 tests covering:
+  - Shows toast when level="all" and category not muted
+  - Suppresses toast when level="none"
+  - Suppresses info toast when level="errors"
+  - Shows error toast when level="errors"
+  - Suppresses toast when category is muted
+  - Defaults to showing toast when no config present
+
+**File:** `apps/web/src/components/toast-rules.test.ts` *(modified)*
+- Extended existing tests with category/severity mapping tests
+- Added preference filtering tests
+
+## Changed Files
+1. `apps/web/src/components/event-toast-bridge.tsx` — Preference checks before toast
+2. `apps/web/src/components/toast-rules.ts` — Category/severity mapping
+3. `apps/web/src/components/toast-rules.test.ts` — Extended tests
+4. `apps/web/src/pages/settings.tsx` — Notification preferences UI
+5. `apps/web/src/api/settings.ts` — API types for preferences
+6. `apps/web/src/components/event-toast-bridge.test.tsx` *(new)* — Bridge tests
+
+## TDD Cycle Evidence
+
+| Cycle | Task | RED | GREEN | Evidence |
+|-------|------|-----|-------|----------|
+| 1 | toast-rules mapping | Tests written against missing functions | Implemented `mapEventToCategory`, `mapEventToSeverity` | Tests pass |
+| 2 | EventToastBridge preferences | Tests written against missing config checks | Added preference checks to bridge | Tests pass |
+| 3 | Settings UI | Manual verification | Added preference section to settings page | Functional |
+| 4 | REFACTOR | — | tsc + eslint clean | All pass |
+
+## Test Commands & Exit Codes
+
+```bash
+# Toast rules + bridge tests (17 tests)
+cd apps/web && npx vitest run src/components/toast-rules.test.ts src/components/event-toast-bridge.test.tsx
+# Exit: 0 — 17 passed
+
+# Type check
+cd apps/web && npx tsc --noEmit
+# Exit: 0 — clean
+
+# Lint
+cd apps/web && npx eslint src/components/event-toast-bridge.tsx src/components/toast-rules.ts src/components/toast-rules.test.ts src/pages/settings.tsx src/components/event-toast-bridge.test.tsx src/api/settings.ts --ext ts,tsx --max-warnings 0
+# Exit: 0 — clean
+```
+
+## Surprises / Decisions
+1. **Settings page uses existing form patterns** — Leveraged existing settings form infrastructure rather than creating a new preferences component.
+2. **Graceful config fallback** — When userConfig is missing or lacks notification keys, defaults to showing all toasts (no muted categories).
+
+## Risks
+- **None:** All changes are additive. Preference defaults are safe (show all toasts).

 ## Deviations from Design
 
+### PR-1
 - **SQLAlchemy `metadata` column name conflict:** `Base.metadata` is reserved by SQLAlchemy DeclarativeBase. Used `notification_metadata` as the Python attribute name with DB column name `"metadata"`. In the Pydantic response model, used `Field(serialization_alias="metadata")` so the JSON API still exposes `metadata` as specified.
 - **`created_at` type in Pydantic:** Used `datetime` instead of `str` to leverage FastAPI's automatic ISO serialization.
 
+### PR-2
+- None. All mappings and behaviors match the design spec (section 1.3) and task requirements exactly.
+
+### PR-3
+- **Polling interval management:** The provider uses two `useEffect` hooks plus `startPolling`/`stopPolling` helpers. A race condition between the dropdown effect and the initial start effect in React Strict Mode was discovered and fixed by requiring `unreadIntervalRef.current` to be truthy before the dropdown effect resumes list polling. This ensures `startPolling` always owns initial list fetch.
+- **`formatRelativeTime` utility:** Design did not specify a relative-time formatter. Added a lightweight custom utility (`apps/web/src/utils/time.ts`) rather than installing a date library, per the constraint not to add npm packages.
+
 ## Surprises / Decisions
 
+### PR-1
 1. **SQLite `func.now()` resolution:** `test_list_notifications_orders_by_created_at_desc` failed because multiple rapid INSERTs got identical timestamps. Fixed by explicitly setting `created_at` offsets in the test after creation.
 2. **Pre-existing integration test failures:** ~40 integration tests fail due to missing `asyncpg` module and direct PostgreSQL connection attempts in their custom setup code. These are unrelated to our changes.
 3. **Pre-existing `test_models.py` outdated:** The `test_expected_tables_are_registered` assertion had a hardcoded set missing many newer tables. Updated it to include all current tables (including `notifications`).
 
+### PR-2
+1. **Health monitor `test_health_monitor_unhealthy_creates_warning_notification` required `public_url`:** The health monitor only checks tunnel health when `instance.public_url` is truthy. Without setting it on the test fixture instance, `_derive_status` returned `"running"` instead of `"unhealthy"`, which created an `"info"` notification. Fixed by setting `test_instance.public_url` in the test before calling `_check_instance`.
+2. **Patch target for failure test:** The `test_notification_failure_does_not_block_event_pipeline` patches `src.services.lifecycle_hooks.notification_service.create_notification`. This only works because `lifecycle_hooks.py` imports `notification_service` at module level, making the attribute resolvable by `unittest.mock.patch`.
+3. **No schema migration needed for UserConfig:** Preferences are stored in the existing JSON `config` blob, consistent with the existing pattern (theme, editor, git identity). No Alembic migration required.
+
+### PR-3
+1. **React Strict Mode interval race:** In `NotificationProvider`, the dropdown `useEffect` was setting the list poll interval before the initial-start `useEffect` called `startPolling`, which caused `startPolling` to skip its initial `fetchList()` call. Fixed by adding `&& unreadIntervalRef.current` to the dropdown effect's resume branch, so it only resumes an already-active polling session.
+2. **`toBeInTheDocument` type issues in tests:** Testing-library jest-dom matchers type definitions were not automatically picked up in `.test.tsx` files. The tests run and pass at runtime; the TypeScript LSP warnings are cosmetic and do not block compilation or execution.
+3. **No npm packages installed:** All frontend work was done with existing dependencies (`@phosphor-icons/react`, `react`, etc.). Relative time formatting was implemented with a 20-line custom utility rather than adding `date-fns` or similar.

+## Files Changed (PR-4)
+
+1. `apps/web/src/components/toast-rules.ts` — Added `mapEventToCategory` and `mapEventToSeverity`
+2. `apps/web/src/components/toast-rules.test.ts` *(new)* — 8 unit tests for mapping functions
+3. `apps/web/src/components/event-toast-bridge.tsx` — Fetches user config, listens for `userconfig:updated`, checks preferences before showing toasts
+4. `apps/web/src/components/event-toast-bridge.test.tsx` *(new)* — 9 tests for preference-based suppression, immediate updates, dedup, unmapped events
+5. `apps/web/src/api/settings.ts` — Added `notification_toast_level` and `notification_mute_categories` to `UserConfig` / `UserConfigUpdate`
+6. `apps/web/src/pages/settings.tsx` — Added notification preference controls (toast level select + mute category checkboxes), dispatches `userconfig:updated` on save

+
+## Deviations from Design (PR-4)
+
+- **No global UserConfig context:** The design assumed an existing user-config context. The frontend did not have one, so `EventToastBridge` fetches config on mount via `getUserConfig` and listens for a `userconfig:updated` `CustomEvent` dispatched by the settings page after a successful save. This achieves immediate preference updates without introducing a new provider.
+
+## Surprises / Decisions (PR-4)
+
+1. **Bridge processes events before config loads:** The initial `useEffect` in `EventToastBridge` could process events while `config` is still `null`. Fixed by initializing `config` to `null` and skipping the event-processing effect until config resolves. This prevents toasts from leaking before preferences are known.
+2. **`UserConfig` type extended without breaking existing consumers:** Adding optional fields to `UserConfig` and `UserConfigUpdate` in `api/settings.ts` did not require changes to `sessions.tsx` or `dashboard.tsx` because they only import the API functions, not the types.
+3. **Custom event for immediate updates:** Using `window.dispatchEvent(new CustomEvent("userconfig:updated", { detail: updated }))` in `settings.tsx` and listening in `event-toast-bridge.tsx` is consistent with the existing `refresh-file-tree` custom-event pattern used in `repo-workspace.tsx`.

+    description: |
+      Add ssh_key_ids to ToolInstance so users can select multiple SSH keys
+      from a list when creating or starting a tool instance. Selected keys
+      are mounted into the container user's home directory (~/.ssh).
+    acceptance_criteria:
+      - ToolInstance model has nullable ssh_key_ids JSON column
+      - create_instance endpoint accepts ssh_key_ids list
+      - start_instance endpoint accepts ssh_key_ids override
+      - start_instance mounts all selected SSH keys to {home_dir}/.ssh
+      - Frontend CreateSessionForm shows multi-select SSH key checkboxes
+      - Frontend instance-list shows SSH key multi-select for start/restart
+      - SSH keys are validated (existence, user ownership) before mounting
+    tests:
+      - unit: test_tool_instances_legacy.py (existing baseline)
+      - integration: manual verification of mount behavior
+    estimated_effort: small

+# Exploration: SSH Key Mounting in Config Profiles
+
+## Current State
+- SSH keys are stored in `ssh_keys` table, user-scoped
+- Keys are attached to `GitRepository` via `ssh_key_id`
+- On clone-mode instance start, the repo's key is mounted to `/root/.ssh`
+- `prepare_ssh_key_files` writes to `instance_dir/.ssh`
+- Only works for clone mode; always mounts to `/root/.ssh`
+
+## Problem
+1. Keys are tied to repositories, not selectable per-instance or per-profile
+2. Always mounted to `/root/.ssh`, not the container user's home dir
+3. Only clone-mode instances get SSH keys; mount-mode instances can't use SSH
+
+## Solution
+Add `ssh_key_id` to ConfigProfile. When a profile with an SSH key is applied:
+1. Fetch the SSH key
+2. Stage decrypted files to `instance_dir/mounts/ssh/.ssh`
+3. Add volume mount to compose: `instance_dir/mounts/ssh/.ssh` → `{home_dir}/.ssh`
+4. This works for all instance types (manifest, legacy, clone, mount)
+
+## Files to Change
+- `apps/api/src/models/config_profile.py` — add `ssh_key_id` column
+- `apps/api/alembic/versions/` — migration
+- `apps/api/src/services/config_profile_resolver.py` — resolve + apply
+- `apps/api/src/services/ssh_keys.py` — allow custom output subdir
+- `apps/api/src/api/config_profiles.py` — CRUD + validation
+- `apps/web/src/api/config_profiles.ts` — type + API
+- `apps/web/src/pages/config-profiles.tsx` — SSH key selector UI
