+# *arr Stack
+
+The *arr automation stack runs on **FrankBook-Pro** (the Mac mini) as quadlets
+inside its podman machine; all egress rides the gluetun WireGuard netns. The
+per-service pages ([[Prowlarr]], [[Sonarr]], [[Radarr]], [[Lidarr]],
+[[Readarr]], [[qBittorrent]]) carry deployment facts; this page holds the
+cross-cutting API and auth-posture procedures.
+
+## API version split (memorize before any *arr HTTP call)
+
+- Sonarr/Radarr: `/api/v3/…`; Lidarr/Readarr/Prowlarr: `/api/v1/…`.
+- Prowlarr is port **9696** — 8090 is Jackett.
+- **Empty body = endpoint absent**, not a failure: probe endpoints by status
+  code first; v1 has no `/api/v1/profile` endpoint at all.
+- `PUT /downloadclient` and `PUT /indexer/{id}` take a SINGLE resource object
+  (GET it, patch `settings`, PUT the whole object back). An array body fails
+  with `Path: $ | BytePositionInLine: 1`.
+- API keys live in each container's config:
+  `podman exec <svc> grep -o "<ApiKey>[^<]*" /config/config.xml | cut -d">" -f2`.
+  They are local-only secrets — they stop being secret the moment a vhost
+  serves the API unauthenticated.
+
+## Schema-first probing (validators are free documentation)
+
+Send the FULL schema template object with fields filled; v1 validators reject
+partials, and each error names the next required field — peel validators one
+live call at a time instead of guessing payload shapes:
+
+- `'Fields' must not be empty` → send a full schema copy, not `fields:[]`.
+- `'Base Url' must not be empty` when keys were camelCase → **PascalCase is
+  required** (`BaseUrl`, `ApiKey`) — schema keys, not the JSON wire keys.
+- `DefaultMetadataProfileId must be > 0` → fetch real ids from
+  `GET /api/v1/metadataprofile` (rows like `(1,'Standard')`);
+  `GET /api/v1/qualitydefinition` returns the quality CATALOG — ids ≠
+  profiles.
+- `targetType null` → configContract not registered in that build (this
+  Prowlarr build has no Prowlarr-plugin indexer; integration is
+  Torznab-family only).
+- `testingPackageId` in a PUT body downgrades validation failures to
+  warnings.
+- `syncLevel` is enum `ApplicationSyncLevel` — omit it or use the int; a
+  string is rejected.
+
+**Verification rules:** `POST /downloadclient` returns the COLLECTION, not
+the created object — verify via GET. Test endpoints return verdicts in the
+BODY at HTTP 200 (`{}` = pass, a list = fail) — judge from bodies, not
+status codes. Command POSTs (`MoviesSearch`, `ApplicationSync`) run
+server-side and respond only when the work finishes: curl `-m` timeouts
+(HTTP 000) during a search are NOT failures — poll queue/history afterward
+instead of re-firing; warm small commands (`RefreshMonitoredDownloads`)
+answer in ~20 ms, so a hang means live work in progress, not a dead API.
+
+**DB as arbiter:** when endpoint shapes are opaque, stop the container and
+edit `/opt/prowlarr/config/prowlarr.db` with `sudo python3` sqlite directly,
+then start. The indexers table columns are
+Id/Name/Implementation/Settings/ConfigContract/Enable/Priority/Added — the
+enable flag column is `Enable` (not `EnableRss`). Prowlarr's real application
+settings values live in `prowlarr.db` → `Applications.Settings` JSON (the
+`/api/v1/applications` GET responses carry `fields: []`).
+
+## Auth posture probe (ground truth is behavior, not config flags)
+
+`AuthenticationMethod=None` + `AuthenticationRequired=Enabled` in
+`config.xml` is ambiguous on paper; on the wire it means a login screen with
+**zero users** — first-account-wins.
+
+1. **Confirm which host runs the service before probing** (`podman ps` on
+   the target, not the box you ssh'd into first — the arrs live on
+   FrankBook-Pro).
+2. Probe an API endpoint that bypasses the SPA shell, locally and through
+   any vhost: `curl -s -o /dev/null -w "%{http_code}"
+   http://<host>:<port>/api/v3/system/status`. **SPA roots (`/`) always
+   serve a 200 shell — never conclude "open" or "gated" from `/`.**
+   401 = gated; 200 + JSON = API fully open (anyone on the net can drive it
+   with curl).
+3. For config truth, dump the whole file
+   (`podman exec <svc> cat /config/config.xml`), not a piped
+   `grep | sed -n 2p`: **`sed -n Np` exits 0 on zero matches**, so the
+   pipeline hides a miss and you conclude "empty field" when the grep itself
+   failed.
+4. Decision framing: when posture = gated-with-zero-users, present it as a
+   decision menu (None behind the front-door wall vs External/authentikarr),
+   not a silent change — first-account-wins means whoever logs in first owns
+   the instance.
+
+## The `None` + `Enabled` auth-config trap (v1 .NET apps)
+
+`<AuthenticationMethod>None</AuthenticationMethod>` +
+`<AuthenticationRequired>Enabled</AuthenticationRequired>` is
+self-contradictory: the UI Save is permanently disabled, and any save throws
+`DryIoc.ScopedItemException` in `AuthorizationMiddleware` → 500 on every
+page after restart. The valid no-auth representation is **absence of the
+`<AuthenticationRequired>` key**, not the literal string `Disabled`. Fix =
+delete the key from `/config/config.xml`
+(`sed -i "/<AuthenticationRequired>/d"`), restart the container. Tell-tale:
+one v1 app boots clean while siblings 500-sprawl → diff their config.xml
+auth blocks; the healthy one shows the correct shape. (Prowlarr runs
+`Forms` + `Enabled` healthily — the crash combo is `None`+`Enabled` only.)
+
+General rules that saved the session these came from: container
+`State=running` ≠ app serving — read `podman logs --tail 12 <c>` before
+theorizing; when a UI gate blocks saving, go under it (these apps keep
+plaintext XML config on disk — read/edit via `podman exec`).
