Claudio 8a17a8dcf5 docs(mule-image): OIDC auto-redirect + deploy.sh caveat 
LoginPage now bounces straight through Authentik when OIDC is on,
with skipAutoSso escape hatches for logout / error / explicit
password use. Also flagging that the first deploy.sh --force-recreate
run raced with a manual --no-deps recreate and broke the stack;
recovery via docker compose down && up.

# 120 — `mule-images`
Hosts `mule-image` / "mulita" — the photos app at `photos.hubris.network`. Auto-deploys from `dtoro/mule-image` on `git push origin main`.
## At a glance
- **Hostname:** `mule-images`
- **IP:** `192.168.8.136`
- **Privilege:** privileged
- **Resources:** 4 cores / 8 GiB RAM / 60 GiB rootfs
- **Mounts:** `/mnt/library` ↔ `/mnt/library`
- **Public hostname:** [`photos.hubris.network`](../infrastructure/dns.md) → [caddy](121-caddy.md) → `:3000` (frontend)
## Stack (`/opt/mule-image`)
`/opt/mule-image` IS the working tree of `dtoro/mule-image`. Compose at `/opt/mule-image/docker-compose.yml`. Services:
| Service | Port | Notes |
| ----------------- | ------ | ----- |
| frontend | 3000 | Reverse-proxied by Caddy |
| backend | 8001 | FastAPI |
| worker-vision | — | ML scan worker |
| worker-light | — | Lightweight worker |
| worker-watcher | — | FS watcher |
| db | (pg) | pgvector |
| redis | (rd) | queue |
`.env` is **untracked** — `git checkout .env` will wipe it. Holds:
- `PHOTO_DIRS=/mnt/library/images/`
- `NEXTCLOUD_USERS_HOST_PATH=/mnt/library/homecloud`
- `NEXTCLOUD_BASE_URL=https://cloud.hubris.network`
- OIDC client secret + scopes
- `SECRET_KEY` (generated)
## Nextcloud-rooted libraries (since 2026-04-26)
Photo libraries live under each user's Nextcloud `files/` tree, NOT in `/mnt/library/images/*`.
- `/mnt/library/homecloud` is bind-mounted into `backend`, `worker-light`, `worker-watcher`, `worker-vision` as `/nextcloud-users`. Each NC user is `/nextcloud-users/<nc_user>/files/`.
- Reads use that bind directly.
- Mutations (upload, delete, rename, move) dispatch through `services/nextcloud_dav.py` (HTTP Basic auth, per-user app password Fernet-encrypted in `users.nextcloud_app_password_enc`) so Nextcloud's `oc_filecache`, trashbin, comments, and desktop-sync clients stay coherent.
- Photo copy + cross-system moves return 501 with a "use Nextcloud's web UI" hint — defer until needed.
- `users.nextcloud_username` overrides the default OIDC `preferred_username`. **`dtoro` (mule-image) maps to `admin` (Nextcloud)** — don't assume username equality.
- Surviving SourceRoots in DB: `Photos` → `/nextcloud-users/admin/files/Photos`; `Memories` → `/nextcloud-users/admin/files/Memories` (both owned by `dtoro`). User `muli` has `nextcloud_username=muli` backfilled but no SourceRoot yet.
- Pre-migration DB dump: `/root/snapshots/mulita-pre-nc-migration-20260426-075132.dump` (11 MB) on the host.
## Authentication (since 2026-04-22)
Native OIDC via Authentik. Code in `backend/app/auth_oidc.py`, routes `/api/v1/auth/oidc/{login,callback}`. Authentik side:
- OAuth2/OIDC Provider, client ID `fCuHew48ONTskDjUKnMTZjFbVXuHwvQqTScQRNQ1`
- App slug `mule-image`
- Redirect URI: `https://photos.hubris.network/api/v1/auth/oidc/callback`
Backend container needs `extra_hosts: auth.hubris.network:192.168.8.175` via `docker-compose.override.yml` (gitignored). Otherwise Authlib's metadata fetch fails with `SSL: CERTIFICATE_VERIFY_FAILED: self-signed certificate` (it ends up at a random public host because LXC DNS resolves the public IONOS A record).
Caddyfile stays plain `reverse_proxy 192.168.8.136:3000` — no forward-auth, no `/api/*` bypass needed.
## Auto-deploy
Push to `dtoro/mule-image` `main` → gitea webhook → `http://192.168.8.136:9797/deploy` → `mule-deploy-webhook.service`:
- Validates HMAC against `/etc/mule-deploy/secret`
- Filters to `refs/heads/main`
- Runs `/opt/mule-deploy/deploy.sh` in a daemon thread (returns 202 immediately — docker builds exceed gitea's request timeout)
- `git pull --ff-only` + `docker compose up -d --build` + `docker image prune -f`
Deploy tooling is **outside** the app repo: `/opt/mule-deploy/{deploy.sh,webhook.py}`, secret at `/etc/mule-deploy/secret`, unit at `/etc/systemd/system/mule-deploy-webhook.service`. Same shape as the Caddy + Artifacto pipelines. Gitea webhook id 6.
`app.ini` `ALLOWED_HOST_LIST` on [gitea](104-gitea.md) includes `192.168.8.136`.
Logs: `pct exec 120 -- journalctl -u mule-deploy-webhook -f`.
Manual deploy: `pct exec 120 -- /opt/mule-deploy/deploy.sh`.
For pushes from inside the LXC, gitea creds at `/etc/mule-deploy/git-credentials` (mode 600) — same token as `/etc/caddy-deploy/git-credentials` on [caddy](121-caddy.md).

## Changelog
### 2026-05-10 — OIDC auto-redirect on LoginPage
`OIDC_ENABLED=true` was already set in `.env`, so the LoginPage rendered a "Sign in with Authentik" button next to the password form. With a single trusted IdP and a logged-in Authentik session, that extra click was friction without upside.
`LoginPage.tsx` now reads `/auth/config` on mount and, if OIDC is on, immediately navigates to the OIDC login URL. Authentik recognizes the existing session and bounces back through the callback with no user interaction. Two escape hatches: `?password=1` in the URL forces the password form, and a `skipAutoSso` sessionStorage flag (set by `AuthContext.logout` and by the OIDC callback's error branch) suppresses the next auto-redirect so logouts actually log out and OIDC failures surface their error instead of looping. While the redirect is in flight the page shows "Signing in with Authentik..." plus a "Use password instead" link.
### 2026-05-10 — right sidebar restructure (heap pinned, single scroll, collapsible Metadata)
The right sidepanel had three stacked flex regions: `<ActiveHeapCard />`, `<Header />`, and `<PhotoInfoPanel />` — with `PhotoInfoPanel` carrying its own internal scroll. That left the editable fields (filename, title, notes, rating, color, flag) stuck above the readonly metadata scroll, effectively two scroll boundaries on one sidebar.
- Moved the scroll boundary up to `RightSidebar.tsx`: only `ActiveHeapCard` and `Header` stay pinned now. Editable + readonly content scroll together in one `flex-1 overflow-y-auto` region beneath them.
- `PhotoInfoPanel.tsx` dropped its `h-full` / inner `flex-1 overflow-y-auto`.
- The four readonly sections (Tags / Basic Info / Camera / Location) are now wrapped in a single outer "Metadata" `Collapsible`. Default expanded, one click hides the whole block. Sub-sections stay individually collapsible.
- Second pass: the editable form (filename / title / notes / rating / color / flag) got the same treatment under an outer "Edit" `Collapsible` so the panel is now two equal collapsible groups below the title strip. Dropped the X (clear-selection) button from the Header; Esc and grid-empty-area-click still clear.
- Third pass: split editable vs read-only between the two groups consistently. `TagsEditor` and `TakenAtEditor` had been buried inside the readonly Metadata sub-sections — `Tags` as its own Section, taken-at wedged into `Basic Info` between size/dims and the filepath. Moved both into the Edit collapsible, ordered identification → description → categorization: Filename · Title · Date Taken · Notes · Tags · Rating · Color · Flag. Metadata now holds only readonly: `Basic Info` (size, dims, path), `Camera`, `Location`.
`PreviewView` reuses `RightSidebar` under an `<aside class="overflow-hidden">`, so the change applies in both the grid sidebar and the preview overlay.
### 2026-05-10 — `photos.hubris.network` perf sweep
User reported slow load. Five fixes shipped, in order:
1. **Backend out of dev mode.** `docker-compose.yml` `command:` was running `uvicorn … --reload` (single worker, file-watcher). Page loads fan out ~15 parallel API calls; they all serialized on one event loop. → `--workers 2 --proxy-headers`. Two uvicorn worker procs now.
2. **iPhone Apple ProRAW / Linear DNG decode fixed.** rawpy 0.26.1 + LibRaw 0.22 rejects Apple Linear DNG (`Photometric Interpretation: Linear Raw`, 8-bit) as "Unsupported file format or not RAW file". Those files are TIFF containers with developed RGB inside and have no embedded preview to fall back to. Added PIL `Image.open(src_path)` as the last fallback in both `_generate_proxy_webp` (routers/photos.py) and `process_raw_image` (tasks/thumbs.py). ~1,300 iPhone DNGs were 415-ing on every detail view; now decode in <1s via PIL.
3. **Reconcile DB with disk (renamed-folder case).** `prune_missing_photos` was skipping all 4,154 orphaned photo rows under SourceRoot `Taco and Muli - 2024 onward` (renamed in Nextcloud to `Photo Archive 2004-2024`) because the leaf path didn't resolve and the code assumed "drive unmounted → must skip". Added `_sr_state()` to classify as `present` / `renamed` (parent mount fine, leaf gone) / `unmounted` (parent inaccessible). Only `unmounted` still skips. Two stale source roots logged with a clearer hint pointing at `POST /api/v1/library/maintenance/prune-missing`. User has not yet been asked to run that — endpoint is ready when they are.
4. **Frontend page size + idle polling.** `usePhotosQuery.ts` was first-fetching `per_page=500` (slow paint + 500 thumb requests at once). Split into `PER_PAGE_INITIAL=100` for first paint, `PER_PAGE_BACKGROUND=500` for the cursor-chain prefetch. Idle polling for `scan-status` and `worker-status` (`useScanActivity.ts`, `ScanProgress.tsx`) bumped from 10s/15s to 30s/30s while idle; active cadence (2s/3s) unchanged.
5. **Partial index on `photos`.** Default list query `WHERE NOT is_trashed AND NOT is_hidden ORDER BY taken_at DESC NULLS LAST, id DESC LIMIT N` was doing a seq-scan + top-N heapsort (~25ms standalone, worse under concurrency). Added migration `0017_photos_list_index` creating `ix_photos_list_visible` (partial index on the sort key, restricted to visible rows). EXPLAIN now shows an Index Only Scan → **24.7ms → 0.097ms**, ~250× speedup.
**Deploy gotcha — fixed (with caveat).** The original `docker compose up -d --build` in `deploy.sh` did not reliably recreate containers when only runtime config (`command:`, env-only) or migration files changed; image hash would change but compose treated the existing container as "current enough". Bit three times this session before `/opt/mule-deploy/deploy.sh` was updated to `docker compose up -d --build --force-recreate`. Trade-off accepted: an extra restart cycle on deploys where nothing user-visible changed.
**Caveat:** the first auto-deploy after the flag flip raced with my own earlier manual `docker compose up -d --no-deps --force-recreate frontend` and landed the stack in a half-broken state — `mulita-frontend` got stuck under a renamed temp container, several services dropped off `mule-image_mulita-network`, frontend nginx restarted in a loop with `host not found in upstream "backend"`. Fixed by `docker compose down && docker compose up -d`. Don't issue a manual `--force-recreate` on a single service while the auto-deploy webhook is also expected to fire — let the deploy own the lifecycle.
**Data drift still outstanding.** 4,154 photo rows + 1 unregistered folder (`Photo Archive 2004-2024`) on disk that's not a SourceRoot. The reconcile endpoints now work — user decides when to call them. The new folder needs to be added as a SourceRoot via the Settings UI before its files will be indexed.
**Proxy cache still empty** (`mule-image_proxies_data` volume is 4 KB). Pre-generating ~500–1,500 WebP proxies for non-web-safe formats would make first-open of every RAW/HEIC photo instant. Deferred — needs a one-shot script and the disk-space tradeoff isn't worth it until the data-drift reconcile happens first.
