spec(grafana-metric-gateway): add proposal

Route metric queries through Grafana /api/ds/query instead of direct Prom
(Prom is firewalled / unreachable from Manage; Grafana is the only path).
Partial revert of prometheus-direct-charting: keep the gauge/mean/
LineSeriesChart rendering, restore the frames->series normalizer (recovered
from git 65bae95), change prometheus service config to hold Grafana gateway
fields (url + api_key + datasource_uid). Rename widgets to neutral Metric*.
First non-additive canonical sync (prometheus-charting MODIFIED). Updates the
pending service-credential-tester proposal dependency.

+}
+```
+
+Headers: `Authorization: Bearer {api_key}`, `Content-Type: application/json`
+
+**Response** (abbreviated):
+
+```json
+{
+  "results": {
+    "A": {
+      "frames": [{
+        "data": { "values": [[1000, 2000], [0.5, 0.8]] },
+        "schema": { "fields": [{"name":"Time"}, {"name":"cpu_usage"}] }
+      }]
+    }
+  }
+}
+```
+
+## Series normalization logic
+
+Iterates `results[*].frames[]`. For each frame with `values` having >=2 arrays (timestamps + values), extracts the series label from `schema.fields[-1].name` and zips timestamps+values into `[{t: int, v: float|null}]`. Returns `{"series": [{"label": "...", "points": [...]}]}`.
+
+## Frontend chart rendering
+
+`GrafanaChartWidget` fetches widget data, extracts `data.series`, merges all series by timestamp into a single recharts data array (`[{time, cpu_usage: 0.5, mem: 0.3}, ...]`), and renders a `<LineChart>` with one `<Line>` per series. Uses Tailwind CSS variables (`--chart-1` through `--chart-5`) for colors so it respects dark mode. Includes loading skeleton, error Alert, and empty-state Alert.
+
+## Validation
+
+```
+cd backend && .venv/bin/ruff check . && .venv/bin/python -m pytest  → 279 passed, ruff clean
+cd frontend && npm run lint && npm run build && npm run test         → 127 passed, lint/build clean
+```
+
+## Deviations
+
+1. **No deviations from spec.** The `link` widget kind is unchanged. The `panel` kind is fully replaced by `chart`.
+2. **recharts `labelFormatter` type workaround.** Recharts 3.x types `labelFormatter` as `(label: ReactNode, ...) => ReactNode`, not `(number) => string`. Wrapped with `(label) => formatTime(Number(label))` to satisfy TS strict.

+
+## Residual risks
+
+- The chart widget assumes the Grafana datasource is Prometheus-type (hardcoded `"type": "prometheus"` in the query body). If the user has a non-Prometheus datasource (InfluxDB, etc.), the query body format may need adjustment. The `datasource_uid` is configurable but the `type` is not.
+- recharts is ~45KB gzipped added to the bundle.

+# Service IA Refinement — Instance Tabs + Config to Settings
+
+## Files changed (5 files, +310/-381)
+
+| File | Status | Lines |
+|------|--------|-------|
+| `frontend/src/integrations/navEntries.ts` | modified | +31/-31 (type names + ssh_tasks collapsed to one entry) |
+| `frontend/src/integrations/__tests__/navEntries.test.ts` | modified | +23/-23 (updated labels) |
+| `frontend/src/pages/ServicePage.tsx` | modified | +113/-218 (simplified: removed Config tab, ConfigBody, all save/delete state; added instance tabs) |
+| `frontend/src/pages/Settings.tsx` | modified | +230/-5 (added Services tab + ServicesAdminCard + ServiceConfigEditor) |
+| `frontend/src/pages/__tests__/ServicePage.test.tsx` | modified | +76/-76 (removed Config/secret tests, added instance-tabs tests) |
+
+## New ServicePage structure
+
+The service page is now a **pure operational view** — no save/delete/config state at all.
+
+**When >1 enabled sibling:**
+
+```
+[Main Jellyfin] [Backup Jellyfin]     ← instance tabs (click to navigate)
+[Overview] [Media] [Requests] [Widgets] ← content tabs
+<content>
+```
+
+**When 1 instance:**
+
+```
+[Overview] [Media] [Requests] [Widgets] ← content tabs only
+<content>
+```
+
+- 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).
+
+## Validation
+
+```
+cd frontend && npm run lint   → 0 errors, 0 warnings
+cd frontend && npm run build  → ✓ built (tsc -b + vite)
+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.

+| `frontend/src/pages/service-tabs/stubs.tsx` | **deleted** | -19 |
+
+## 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
+
+```
+cd backend && .venv/bin/ruff check .                    → All checks passed!
+cd backend && .venv/bin/python -m pytest tests/         → 272 passed, 2 warnings

+```
+
+## 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.
+
+## skill_resolution
+
+`none` — no project/user SKILL.md paths were injected; no `.atl/skill-registry.md` found.
+
+## 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).

+## Session-filter logic for now_playing
+
+```python
+if widget_kind == "now_playing":
+    sessions = [
+        s for s in sessions
+        if s.get("NowPlayingItem")
+        and not s.get("PlayState", {}).get("IsPaused", True)
+    ]
+```
+
+Filters raw Jellyfin sessions BEFORE `_map_sessions_to_activity_rows`. A session is "actively playing" when it has a `NowPlayingItem` (something is playing, not just idle) AND `PlayState.IsPaused` is false. The `activity` kind (default) is unchanged — shows all sessions including idle and paused.
+
+## Embed URL format for panel
+
+```python
+embed_url = f"{base_url}/d-solo/{dashboard_uid}/manage?panelId={panel_id}&from={from_ts}&to={to_ts}&kiosk=tv"
+```
+
+Uses Grafana's `/d-solo/` endpoint which renders a single panel without dashboard chrome. `kiosk=tv` hides the top nav. Defaults: `from_ts="now-1h"`, `to_ts="now"`.
+
+## Validation

+
+## Deviations
+
+1. **No deviations from spec.** Both widgets are additive — no existing behavior changed. The `activity` and `link` kinds work exactly as before.
+2. **GrafanaPanelWidget pi-lens advisory** for `<Button asChild><a>` is a false positive (Radix Slot merges props, doesn't create nested `<a>`). Same pattern as GrafanaLinkWidget, ObservabilityPage, and PinnedServiceLink. Build and lint pass.
+
+## skill_resolution
+
+`none` — no project/user SKILL.md paths were injected; no `.atl/skill-registry.md` found.
+
+## Residual risks
+
+- **Grafana embedding may be blocked** by `X-Frame-Options` or CSP depending on Grafana config. The fallback "Open in Grafana" link is provided.
+- **GrafanaPanelWidget iframe height is fixed at 300px** — not responsive to panel content height. A follow-up could use Grafana's panel-content-height API or a ResizeObserver.
+- **now_playing filter operates on raw sessions before mapping** — if Jellyfin changes its session shape (e.g. moves `NowPlayingItem`/`PlayState`), the filter silently passes all sessions. Same fragility as the existing activity mapping.

 ## [Unreleased]
 
+### Added — Direct Prometheus charting
+
+- **Prometheus is now the direct source for in-app charts.** New widget kinds
+  on the `prometheus` service: `chart` (multi-series line chart via recharts,
+  backed by `/api/v1/query_range`), `gauge` (instant scalar with configurable
+  threshold bands), and `mean` (client-side average over a time window).
+
+### **BREAKING** — Grafana service type removed
+
+- The `grafana` service type, Grafana link widget, Grafana chart widget, and
+  `GET /api/monitoring/grafana-status` endpoint were **removed**. Manage now
+  queries Prometheus directly for all chart data.
+- **Migration:** Delete any existing Grafana service instances and create
+  Prometheus service instances instead (pointing at your Prometheus URL). Any
+  configured `grafana/chart` widgets must be recreated as `prometheus/chart`
+  widgets. Grafana link widgets are gone — use Prometheus chart/metric widgets
+  instead.
+
 ### Added — Observability service registry
