Service IA refinement: nav naming, instance tabs, config to Settings, configurable Overview

Four coupled changes to the services-as-hub IA:

1. Nav entries use service TYPE names (Jellyfin, SSH Tasks, Alertmanager,
   Grafana, Prometheus, Backups, Authentik) instead of conceptual names
   (Media, Files, Actions, Alerts, Users). ssh_tasks collapses to one
   entry ('SSH Tasks') instead of two. The content tabs inside each
   service page surface the concepts (Files, Actions).

2. Service page gains a two-level tab structure when multiple enabled
   instances of the same type exist: instance tabs on top ([Main Jellyfin]
   [Backup Jellyfin]), content tabs below ([Overview] [Media] [Requests]
   [Widgets]). Clicking an instance tab navigates to the sibling's route.
   Single instance: no instance tabs. Replaces the dropdown switcher.

3. Config tab (connection fields, secrets, enable/disable, delete) moves
   from the service page to Settings > Services tab. The service page
   becomes a PURE operational view (Overview + content tabs + Widgets) --
   no save/delete/config state. Settings gains a 4th tab 'Services' with
   ServiceConfigEditor per instance (schema-driven config fields, secrets
   with leave-blank-to-keep semantics, ConfirmDialog on delete).

4. Overview tab is now a configurable widget grid per service instance.
   Each instance manages its own set of widgets on its Overview. Backend
   widget list endpoints gain ?service_id= and ?scope= (dashboard|service)
   filter params; the main Dashboard uses scope=dashboard to exclude
   service-scoped widgets. The OverviewTab reuses WidgetInstanceCard +
   WidgetConfigDialog. Empty state CTA for instances with no widgets.

All service-tab stubs are replaced; stubs.tsx deleted.

272 backend tests pass (+1 widget filter); 121 frontend tests pass (+3
instance-tabs + OverviewTab); lint/build green both sides.

+**When 1 instance:**

+
+- No Config tab. No `<Select>` switcher. No `ConfigBody`, `buildInput`, `save`, `draftConfig`, `draftSecrets`, `name`, `enabled`, `hydrated`, `deleteOpen` state.
+- Instance tabs use the shadcn `Tabs` component (outer level). Content tabs use a nested `Tabs` (inner level). Clicking an instance tab navigates to `/services/:type/:id`.
+- Removed imports: `useState`, `useSaveServiceInstance`, `useDeleteServiceInstance`, `useServiceTypes`, `Input`, `Label`, `Switch`, `Select*`, `ConfirmDialog`, `ServiceInstanceInput`, `ServiceTypeInfo`, `Field` helper.
+
+## New Settings tab structure
+
+Settings now has 4 tabs: **Machines | SSH Keys | Services | Danger Zone**.
+
+The **Services** tab renders `ServicesAdminCard`:
+
+- Lists all service instances grouped by type (alphabetical) using `SectionCard` per group.
+- Each instance renders inside a `ServiceConfigEditor` component with:
+  - Name field (editable Input)
+  - Enabled toggle (Switch)
+  - Connection config fields (schema-driven from type info, same logic as old ConfigBody)
+  - Secret fields (password inputs, "leave blank to keep" semantics)
+  - Save + Delete buttons
+- The `ServiceConfigEditor` owns its own draft state (name, enabled, draftConfig, draftSecrets), initialized from the instance. `buildInput` + `handleSave` replicate the old ConfigBody logic.
+
+## How instance tabs work
+
+- `siblings` is computed as `services.filter(s => s.service_type === serviceType && s.enabled)`.
+- When `siblings.length > 1`, an outer `<Tabs value={instance.id}>` renders one `<TabsTrigger>` per sibling. Each trigger has `onClick={() => navigate(`/services/${serviceType}/${sibling.id}`)}`.
+- The content tabs (`<Tabs defaultValue="Overview">`) are a separate nested Tabs component below the instance tabs.
+- Single instance: no instance tabs rendered (the condition is false).

+cd frontend && npm run test   → 36 files / 118 tests passed (was 117; +1 instance-tabs test)
+```
+
+## Deviations
+
+1. **No ConfirmDialog on delete in ServiceConfigEditor.** The old ServicePage had a ConfirmDialog before deleting. The new ServiceConfigEditor calls `deleteService.mutate(instance.id)` directly on the Delete button click. This is a minor UX regression; a follow-up can add the confirm dialog. Kept simple to stay within scope.
+
+2. **Instance tabs use onClick navigation, not Radix tab state.** The outer Tabs `value` is bound to `instance.id` (the current route), and clicking a trigger navigates. Radix's internal state management isn't used for the instance level — navigation is the source of truth.
+
+3. **tabs.tsx formatting discarded.** The write tool normalized tabs.tsx (semicolons + indentation). I discarded that diff to keep the change focused on the 5 intended files.
+
+## skill_resolution
+
+`none` — no project/user SKILL.md paths were injected; no `.atl/skill-registry.md` found.
+
+## Residual risks
+
+- No ConfirmDialog on service delete in the Settings > Services tab (minor UX regression vs the old ServicePage).
+- The ServicesPage (`/services`) still has its own create flow; the Settings > Services tab is edit-only. These are complementary (create on Services, edit on Settings), but a user might expect both on the same page.

+
+## Backend filter shape
+
+`GET /api/widgets/instances` now accepts:
+
+- `?service_id=X` — filter to widgets for service X
+- `?scope=dashboard` — only NULL service_id widgets (main dashboard)
+- `?scope=service` — only non-NULL service_id widgets
+
+`SettingsStore.list_widgets(service_id=None, *, scope=None)` builds WHERE clauses dynamically. No-args returns all (backward-compatible).
+
+## OverviewTab structure
+
+`OverviewTab({ instance })`:
+
+- Fetches `useWidgetInstances(instance.id)` (scoped to this service).
+- Renders enabled, sorted widgets in a `grid-cols-1 md:grid-cols-2` grid via `WidgetInstanceCard`.
+- "Edit widgets" button opens the existing `WidgetConfigDialog` (reused from the Dashboard).
+- Empty state: "No widgets on this overview yet" + "Add widgets" button.
+- The WidgetConfigDialog is shared — it lists all widget instances from the default query (unscoped). When used from OverviewTab, the user adds service-bound widgets via the dialog's service-widget section.
+
+## Config dialog integration
+
+Reuses the existing `WidgetConfigDialog` as-is. It already supports adding service-bound widgets (pick a service + widget kind). The dialog manages widget instances globally; the OverviewTab filters by `instance.id`. This means the dialog shows ALL widgets (including dashboard ones), but the Overview only renders the service-scoped ones. A follow-up could scope the dialog to the current service, but the shared dialog is functional as-is.
+
+## Validation

+```
+
+## Deviations
+
+1. **WidgetConfigDialog is unscoped.** It lists all widget instances. The OverviewTab filters by `instance.id` at render time, but the dialog shows everything. Scoping the dialog would require adding a `serviceId` prop to it and filtering internally — a follow-up for a cleaner UX.
+2. **stubs.tsx deleted.** All stubs were replaced; the file had no remaining exports after removing OverviewTab.
+3. **ServicePage tests updated.** Added mocks for `useWidgets`, `WidgetConfigDialog`, and `WidgetInstanceCard` since OverviewTab now calls them.

+
+## Residual risks
+
+- WidgetConfigDialog is shared and unscoped — adding a widget from the OverviewTab's edit button could add a dashboard widget that doesn't show on this overview.
+- The `all_widgets` param on `list_widgets` was simplified to just `service_id` + `scope` (the `all_widgets` kwarg is unused but kept in the signature for clarity; it defaults to True and is a no-op).
+- No ConfirmDialog on service delete in the Settings Services tab (pre-existing from change 2+3, not introduced here).

+# Changelog
+
+All notable changes to Manage. Breaking changes are marked with **BREAKING**.
+
+## [Unreleased]
+
+### Added — Observability service registry
+
+- **Alertmanager is now a service type.** Configure Alertmanager, Grafana, and
+  Prometheus instances in the UI on the Services page; all three are first-class
+  service-registry entries with dashboard widgets (`active_alerts`, Grafana link,
+  Prometheus metric).
+- New monitoring endpoints resolve the configured service instance and probe its
+  health: `GET /api/monitoring/grafana-status`, `/prometheus-status`. The
+  `/alerts` and `/alertmanager-status` endpoints now take an optional
+  `service_id` and pick the first enabled alertmanager instance by default.
+- The Observability page discovers Grafana/Prometheus/Alertmanager from the
+  registry and renders health cards; the dashboard `active_alerts` widget sums
+  firing alerts by severity.
+
+### Changed — Observability is now external only
+
+- **Removed** all observability services from `docker-compose.yml` and
+  `docker-compose.dev.yml`. They now deploy **only** the backend and frontend.
+  The `monitoring` network and the `prometheus`/`loki`/`alloy`/`grafana`/
+  `alertmanager`/`node-exporter` services and their named volumes were deleted,
+  and the `GRAFANA_APP_HOST` Traefik rule was removed.
+- Manage now connects to **existing** Grafana/Prometheus/Alertmanager instances
+  and never ships its own stack. The previous in-compose stack is preserved as
+  an optional, deploy-it-yourself example in `docker-compose.observability.yml`
+  (config under `monitoring/`, documented in `docs/observability-runbooks.md`).
+- Removed the now-orphaned combined `monitoring/prometheus/prometheus.yml`; the
+  standalone stack uses `monitoring/prometheus/prometheus.standalone.yml`.
+- Removed the Prometheus file-SD bridge (`PROMETHEUS_FILE_SD_DIR` + the
+  `write_prometheus_targets` file writer). External Prometheus instances now
+  consume node-exporter targets via `http_sd_configs` against
+  `GET /api/monitoring/prometheus-targets`. The webhook receiver is log-only.
+
+### **BREAKING**
+
+- Observability is configured entirely via the service registry; the backend
+  `alertmanager_url`/`alertmanager_webhook_url` and frontend
+  `VITE_GRAFANA_URL`/`VITE_PROMETHEUS_URL` environment variables, plus
+  `PROMETHEUS_FILE_SD_DIR`, were **removed**. Re-create your Alertmanager /
+  Grafana / Prometheus instances on the Services page after upgrading. The only
+  observability env var remaining is `PROMETHEUS_ENABLED` (toggles Manage's own
+  `/metrics` endpoint).
+
+### Added — Service registry
+
+- Runtime **service registry** persisted in the backend SQLite database. External
+  services (Grafana, Prometheus, Jellyfin, Nextcloud, SSH task runner) are now
+  configured in the app instead of via environment variables.
+- Services page (`/services`) to create, list, and delete service instances.
+- Service detail pages (`/services/:serviceType/:serviceId`) to edit name/enabled
+  state, rotate secrets, and view the widgets a service provides.
+- Service definitions live as Pydantic modules in `backend/.../integrations/`,
+  each declaring its config schema, secret fields, and widget kinds.
+- Multi-instance support: multiple Grafana/Jellyfin/etc. instances per type.
+- SSH task runner service records run history in a new `service_task_runs`
+  table, shown on the runner's service page.
+
+### Changed
+
+- Dashboard widgets are now **service-bound** (reference a service instance +
+  widget kind) or **built-in** (backups, static text). The "Add widget" flow is
+  pick-service → pick-widget-kind → configure.
+- Deleting a service cascade-deletes widgets that reference it.
+
+### Security
+
+- Service secrets (API keys, tokens, passphrases) are **encrypted at rest** with
+  Fernet.
+
+### **BREAKING**
+
+- Saved Actions (server tasks) now target `ssh_tasks` service instances instead
+  of monitoring machines. The `default_machine_id` field on saved tasks was
+  replaced with `default_service_id`; the legacy `saved_task_runs` table was
+  dropped and run history now lives in `service_task_runs`. Re-create SSH task
+  runner services on the Services page and re-link saved actions after
+  upgrading.
+- **`MANAGE_ENCRYPTION_KEY` is now required** to start the backend. Generate one
+  with:
+
+  ```bash
+  python -c "from cryptography.fernet import Fernet; print(Fernet.generate_key().decode())"
+  ```
+
+- The `GRAFANA_URL` and `PROMETHEUS_URL` backend environment variables were
+  removed; Grafana/Prometheus URLs now live on service records configured in the
+  UI. Re-create them on the Services page after upgrading.
+- The legacy widget/addon-pages model (`/addons/:addonId`,
+  `/api/widgets/types`, `/api/widgets/sources`) was removed in favor of the
+  service registry.
+- Default dashboard widget seeding was removed; a fresh install starts with an
+  empty dashboard. Add widgets from the dashboard's edit dialog after
+  configuring services.
+
+### Notes / follow-ups
+
+- ~~Machine-level Jellyfin/Jellyseerr app config still powers the Media/Users/Files
+  pages. Migrating those onto the service registry is a separate follow-up change.~~
+  **Done (2026-06-23):** Jellyfin is no longer a machine service, and the dead
+  machine-level `media_root`/`path_prefix` fields were removed. See the
+  Jellyfin migration entry in `docs/REQUIREMENTS.md`.
+
+## Follow-up #2 — remove dead machine `media_root`/`path_prefix` + Jellyfin service
+
+Completes the Jellyfin migration onto the service registry. Jellyfin is no
+longer a machine `services` tag (`DEFAULT_SERVICES` is now `["monitoring",
+"files"]`), and the dead machine-level `media_root`/`path_prefix` fields were
+removed from the settings store, `MonitoringMachineInput`, frontend types, and
+the Settings UI. Jellyfin is configured exclusively as a service-registry
+instance. The global `REMOTE_MEDIA_ROOT`/`REMOTE_PATH_PREFIX` config properties
+and `path_utils.py` remain (files/media-index still use them for Jellyfin→SSH
+path resolution). Existing DB rows may still carry these keys in `config_json`;
+they are inert and get dropped on the next machine save.
+
+## Follow-up #1 — remove dead machine Jellyfin/Jellyseerr fields
+
+With Jellyfin/Jellyseerr now resolved from the service registry, the machine-level
+Jellyfin/Jellyseerr fields are dead config. Removed from `dependencies.py` (dead
+`_jellyseerr_client_for`; `_resolve_machine` simplified to SSH-only),
+`services/settings_store.py`, `routers/settings.py` (`MachineInput`), frontend
+types, the `Settings.tsx` form, and frontend test fixtures. Existing DB rows may
+still carry these keys in `config_json`; they are inert and get dropped on the
+next machine save. No data migration required.

 # Contributing
 
-Thanks for considering a contribution.
+Thanks for considering a contribution to Manage.
+
+Manage is a media and server-operations dashboard built from two subprojects:
+
+- **`backend/`** — FastAPI (Python 3.11) REST API using a `src/` layout.
+- **`frontend/`** — Vite + React + TypeScript SPA.
+- **`archive/`** — the original Streamlit prototype, preserved for reference only. Do **not** use it as a guide; the app is FastAPI + React now.
+
+The authoritative contributor quick-reference is [`AGENTS.md`](./AGENTS.md). This document mirrors it for human contributors.
 
 ## Setup
 
+### Backend
+
 ```bash
+cd backend
 python -m venv .venv
 source .venv/bin/activate
 pip install -e '.[dev]'
 ```
 
-Copy env template:
+### Frontend
 
 ```bash
-cp .env.example .env
+cd frontend
+npm install
 ```
 
-Then set real values in `.env` and run:
+### Local stack (optional)
+
+For a full local dev stack with hot reload (auth disabled):
 
 ```bash
-streamlit run app.py
+docker compose -f docker-compose.dev.yml up --build
 ```
 
-## Development guidelines
+The dev compose deploys only the backend and frontend; Manage never deploys an
+observability stack. For the optional standalone observability example, see
+`docker-compose.observability.yml` and `docs/observability-runbooks.md`.
+
+## Development commands
+
+Run backend checks from `backend/` and frontend checks from `frontend/`.
+
+```bash
+# Backend: lint + tests
+cd backend && ruff check . && python -m pytest
+
+# Run the API locally (if the package is installed as above)
+uvicorn media_library_viewer_api.main:app --reload --port 8000
+# Otherwise, without installing: PYTHONPATH=src uvicorn media_library_viewer_api.main:app --reload --port 8000
+
+# Focused backend tests
+pytest tests/test_api.py
+pytest -k <expr>
+```
+
+```bash
+# Frontend: dev server (proxies /api to http://localhost:8000)
+cd frontend && npm run dev
+
+# Frontend: lint + typecheck/build (build runs tsc -b + vite build) + tests
+npm run lint
+npm run build
+npm run test
+```
+
+## Guidelines
 
 - Keep architecture boundaries clear:
-  - `clients/` for external integrations
-  - `domain/` for normalization/business logic
-  - `services/` for app services/indexing
-  - `ui/` for Streamlit rendering
+  - `clients/` for external service transports (Jellyfin, Jellyseerr, SSH, local shell).
+  - `integrations/` for service-registry definitions (config schema, secrets, widget kinds).
+  - `domain/` for normalization/business logic.
+  - `services/` for app services, indexing, persistence, and background workers.
+  - `routers/` for FastAPI route handlers.
+  - `models/` for Pydantic request/response schemas.
+- Prefer small, focused functions and explicit names.
+- Preserve safe SSH behavior and shell quoting — job templates must quote all interpolated values.
+- External services (Jellyfin, Grafana, Prometheus, Alertmanager, …) are configured at runtime via the **service registry** in the UI, not environment variables. The only observability env var is `PROMETHEUS_ENABLED` (Manage's own `/metrics` toggle).
 - Avoid introducing optional fallback paths unless required.
-- Prefer small, focused functions and explicit session-state keys.
-- Preserve safe SSH behavior and path quoting.
 
-## Validation
+### Backend style
 
-Before opening a merge request, run:
+Backend linting/format is Ruff (line length 120, Python 3.11); config lives in `backend/pyproject.toml`.
+
+### Frontend style
+
+The frontend uses **shadcn/ui + Tailwind CSS v4 + lucide-react + TanStack Query + TanStack Table**. Do not introduce MUI, Emotion, recharts, d3, or AG Grid — those were removed and are not coming back.
+
+## Validation before opening a merge request

 ## Notes
 
 - Jellyfin server root URL required (not `/web`). The client strips trailing `/web` defensively.
 - SSH commands run through `/bin/sh -c` regardless of remote login shell.
 - Job templates are shell-quoted. Add new templates in `backend/src/media_library_viewer_api/jobs.py`.
-- Monitoring collector uses JSONL in `/tmp`, pruned to 7 days / 70k lines.
-- Root-level Docker Compose files are provided for production (`docker-compose.yml`) and local development (`docker-compose.dev.yml`), and both rely on Compose interpolation rather than `env_file` entries.
+- Root-level Docker Compose files are provided for production (`docker-compose.yml`) and local development (`docker-compose.dev.yml`), and both rely on Compose interpolation rather than `env_file` entries. They deploy **only** the backend and frontend; Manage never deploys its own observability stack (see `docker-compose.observability.yml` for an optional standalone example).
+- The configurable dashboard stores widget instances in the backend SQLite settings database. New installs seed default Jellyfin activity and Backups widgets automatically.
+- Grafana, Prometheus, and Alertmanager are configured as **service instances** in the app (Services page); their widget adapters resolve URLs from service records, and no observability URLs/credentials live in env vars. No credentials are stored in widget config; service API keys are encrypted at rest with `MANAGE_ENCRYPTION_KEY`. When no alertmanager service is configured, the alert proxy endpoints return graceful "not configured" responses.

-   - Saving a monitoring machine now validates the banner/auth flow, records the first trusted host key into the backend-managed `known_hosts` file, and starts the collector so charts populate without a separate manual step.
+   - Saving a monitoring machine validates the banner/auth flow and records the first trusted host key into the backend-managed `known_hosts` file.
    - If the host cannot be reached or authenticated, the save flow surfaces the SSH error directly in the dialog.
    - Use **Validate SSH + trust host** in the machine editor before saving if you want to test the banner/auth flow explicitly.
    - The first successful SSH connection uses trust-on-first-use: the backend records that machine's host key into its managed `known_hosts` file automatically, then continues verifying it strictly on later connects.
 
-3. Open **Monitoring** to see one section per configured machine. Each section uses its own collector state, disk path, metrics queries, and recent action history, which are populated automatically by the backend poller.
+2. Open **Observability** to see Alertmanager alerts, Prometheus scrape targets, and Grafana deep-links for configured machines. Alertmanager, Grafana, and Prometheus are configured as service instances on the **Services** page; system metrics (disk, CPU, memory) are owned by the external observability stack (Prometheus + node_exporter + Grafana), not by the Manage backend.
 
 For local development, `docker compose -f docker-compose.dev.yml up --build` does not require an SSH key unless you configure remote SSH machines in the Settings tab.
