# Jellyfin Migration Implementation Plan

> **For agentic workers:** This plan is executed in **Cursor**, not Claude Code. It deliberately
> does **not** use this repo's Claude Code skills (`homelab-apply`, `homelab-ssh`) or MCP servers
> (portainer, uptime-kuma, authentik). Every action is a literal shell command, file edit, or
> named UI step. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Replace host-native Plex on valhalla with containerised Jellyfin, preserving curated
artwork, collections and per-user watch history, then decommission Plex.

**Architecture:** A new Portainer-managed stack `stacks/streaming/` (jellyfin, jellystat +
postgres, wizarr, jellyplex-watched) on the shared `edge` network behind Caddy. Bulk data
(metadata, trickplay, cache, transcodes) binds to `/storage1`; only SQLite config lands on the
97%-full root disk. Plex runs untouched until Task 23.

**Tech Stack:** Docker Compose, Portainer (Gitea git-polling), Caddy, Jellyfin 10.11,
PostgreSQL 16, systemd timers, Uptime Kuma push monitors.

**Spec:** `docs/superpowers/specs/2026-08-05-jellyfin-migration-design.md`

---

## A note on "tests" in this plan

This is deployment configuration, not application code, so there is no test suite to write
first. The TDD discipline is preserved in a different form: **every task states its verification
command and expected output before the change is made**, and no task is complete until that
command produces that output. Treat a failed verification exactly as you would a failing test —
stop and diagnose, do not proceed.

## Conventions this repo enforces

Violating any of these breaks a live system. They are not stylistic.

1. **The repo is canonical.** Editing files here changes nothing until pushed to Gitea.
   Portainer polls `https://gitea.ginnoir.com/ginnoir/homelabstack` on `main` every 5 minutes.
2. **No `${VAR}` interpolation in compose, ever.** Every service gets `env_file: stack.env`, and
   variable names in `stack.env` are exactly what the container reads.
3. **Portainer UI environment variables must be empty** for application stacks. All config comes
   from `stack.env`.
4. **LF line endings only.** `.gitattributes` enforces this. CRLF in `stack.env` appends stray
   `\r` to values and breaks containers silently.
5. **`stack.env` is committed intentionally.** Secrets are versioned in this private repo. Do not
   gitignore or scrub them.
6. **Infra images are version-pinned** with `com.centurylabs.watchtower.enable=false`. Apps run
   `:latest` under Watchtower.

## Host facts you will need

| Fact | Value |
|---|---|
| SSH | `ssh -o BatchMode=yes ginnoir@valhalla` |
| valhalla LAN IP | `192.168.1.69` |
| Plex | host-native systemd unit `plexmediaserver`, data at `/var/lib/plex` → `/storage1/labdata/plex` |
| Plex API | `http://192.168.1.69:32400` |
| Root disk | `/dev/sda2`, 194G, **97% full at plan time** |
| Libraries | `/storage1/Movies`, `/storage1/TV`, `/storage1/Anime` |
| Free ports | 8096, 5690, 3009 all confirmed unused |

---

# PHASE 0 — Disk remediation

**Nothing in Phase 1 may start until Task 4 is complete.** The root disk is at 97% and `/config`
lives on it. This phase is a hard gate.

---

### Task 1: Reclaim Docker disk space

**Files:** none — live host operation.

- [ ] **Step 1: Record the baseline**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "df -h / | tail -1; docker system df"
```

Write the output into the task notes below. Expected at plan time: `/dev/sda2 194G 179G 5.7G 97%`
and roughly `Images 124 / 123.5GB / 51.47GB reclaimable`.

- [ ] **Step 2: Verify no container depends on what you are about to remove**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker ps -a --filter status=exited --format '{{.Names}}\t{{.Image}}'"
```

Expected: a short list, or empty. Any **exited container you still want** keeps its image, so
note them. `docker image prune -a` removes only images not referenced by *any* container,
including stopped ones — it will not break a stopped-but-wanted service.

- [ ] **Step 3: Prune**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker image prune -af && docker builder prune -f"
```

- [ ] **Step 4: Verify space was reclaimed**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "df -h / | tail -1"
```

Expected: `Avail` is now **at least 40G** and `Use%` is at or below **80%**.
If it is not, stop. Do not proceed to Task 2 — investigate what is holding the space.

- [ ] **Step 5: Confirm all containers are still running**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker ps --format '{{.Names}}\t{{.Status}}' | grep -c Up"
```

Expected: **71 or more** (the count before the prune). Watchtower re-pulls anything it needs.

---

### Task 2: Audit what else is consuming the root disk

**Files:** none — live host operation.

- [ ] **Step 1: Find the top consumers outside Docker**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo du -xh --max-depth=2 / 2>/dev/null | sort -h | tail -25"
```

`-x` keeps it on `/dev/sda2` and stops it wandering into the 94T of `/storage1`.

- [ ] **Step 2: Check the Docker containerd image store specifically**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo du -sh /var/lib/docker /var/lib/containerd /var/log 2>/dev/null"
```

This is the directory that caused the 2026-07-07 outage (all Postgres instances crash-looped on
"No space left on device"). It should now be well under 60G.

- [ ] **Step 3: Record findings**

Append the output to this task as a comment. You are looking for anything **structurally
growing** — not one-off large files. If you find a second unbounded growth source, add a task
to this plan to bound it before continuing.

- [ ] **Step 4: Commit the findings**

```bash
git add docs/superpowers/plans/2026-08-05-jellyfin-migration.md
git commit -m "docs(plan): record root disk audit findings"
```

---

### Task 3: Add root-disk free-space alerting

Uptime Kuma cannot inspect disk space directly. The pattern is a **push monitor**: valhalla
reports in on a timer, and reports `down` when free space is low. If the timer stops, Kuma also
alerts — so this catches both "disk full" and "monitoring broke".

**Files:**
- Create on host: `/usr/local/bin/root-disk-check.sh`
- Create on host: `/etc/systemd/system/root-disk-check.service`
- Create on host: `/etc/systemd/system/root-disk-check.timer`

> These are host-managed files, not repo files. valhalla has **no crontab** — systemd timers only
> (this matches the existing `docker-prune.timer`).

- [ ] **Step 1: Create the Uptime Kuma push monitor and capture its token**

In the Uptime Kuma UI at `https://uptime.ginnoir.com`:
1. **Add New Monitor**
2. Monitor Type: **Push**
3. Friendly Name: `valhalla root disk`
4. Heartbeat Interval: `300` seconds
5. Retries: `1`
6. Notifications: tick the existing **ntfy** notification
7. Save

The monitor page then shows a Push URL of the form
`https://uptime.ginnoir.com/api/push/XXXXXXXXXX`. **Copy the token** (the `XXXXXXXXXX` part).

Record it here before continuing — the next step needs it:

```
PUSH_TOKEN = ____________________
```

- [ ] **Step 2: Write the check script on the host**

Substitute your real token for `PUSH_TOKEN_HERE`.

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo tee /usr/local/bin/root-disk-check.sh >/dev/null <<'EOF'
#!/bin/sh
# Reports root-disk headroom to Uptime Kuma. Alerts below MIN_FREE_PCT.
set -eu
MIN_FREE_PCT=15
TOKEN=PUSH_TOKEN_HERE

USED_PCT=\$(df --output=pcent / | tail -1 | tr -dc '0-9')
FREE_PCT=\$((100 - USED_PCT))
AVAIL=\$(df -h --output=avail / | tail -1 | tr -d ' ')

if [ \"\$FREE_PCT\" -ge \"\$MIN_FREE_PCT\" ]; then
  STATUS=up
else
  STATUS=down
fi

curl -fsS --max-time 10 \\
  \"https://uptime.ginnoir.com/api/push/\${TOKEN}?status=\${STATUS}&msg=root%20\${AVAIL}%20free%20(\${FREE_PCT}%25)\" \\
  >/dev/null
EOF
sudo chmod 755 /usr/local/bin/root-disk-check.sh"
```

- [ ] **Step 3: Run it once by hand and verify Kuma turns green**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo /usr/local/bin/root-disk-check.sh && echo OK"
```

Expected: `OK`, and the `valhalla root disk` monitor in Kuma flips to **Up** within a few
seconds with a message like `root 45G free (23%)`.

If it prints a curl error instead, the token is wrong — fix it before continuing.

- [ ] **Step 4: Create the systemd service and timer**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo tee /etc/systemd/system/root-disk-check.service >/dev/null <<'EOF'
[Unit]
Description=Report root disk headroom to Uptime Kuma

[Service]
Type=oneshot
ExecStart=/usr/local/bin/root-disk-check.sh
EOF
sudo tee /etc/systemd/system/root-disk-check.timer >/dev/null <<'EOF'
[Unit]
Description=Run root-disk-check every 5 minutes

[Timer]
OnBootSec=2min
OnUnitActiveSec=5min
AccuracySec=30s

[Install]
WantedBy=timers.target
EOF
sudo systemctl daemon-reload && sudo systemctl enable --now root-disk-check.timer"
```

- [ ] **Step 5: Verify the timer is scheduled**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "systemctl list-timers root-disk-check.timer --no-pager"
```

Expected: one row showing `root-disk-check.timer` with a `NEXT` time under 5 minutes away.

- [ ] **Step 6: Verify the alert path actually fires**

Temporarily raise the threshold so the script reports `down`:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo sed -i 's/^MIN_FREE_PCT=15/MIN_FREE_PCT=99/' /usr/local/bin/root-disk-check.sh && sudo /usr/local/bin/root-disk-check.sh"
```

Expected: the Kuma monitor flips to **Down** and an ntfy notification arrives. Then restore it:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo sed -i 's/^MIN_FREE_PCT=99/MIN_FREE_PCT=15/' /usr/local/bin/root-disk-check.sh && sudo /usr/local/bin/root-disk-check.sh"
```

Expected: monitor returns to **Up**. An untested alert is not an alert.

---

### Task 4: Correct the Plex documentation in CLAUDE.md

`CLAUDE.md` documents a Plex data path that does not exist. Anyone (human or agent) following it
will operate on the wrong directory.

**Files:**
- Modify: `CLAUDE.md` (the `### Plex Media Server` section)

- [ ] **Step 1: Verify the true paths one more time**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "ls -ld /var/lib/plex; readlink -f /var/lib/plex; ls -d /var/lib/plexmediaserver 2>&1"
```

Expected: `/var/lib/plex -> /storage1/labdata/plex`, and
`ls: cannot access '/var/lib/plexmediaserver': No such file or directory`.

- [ ] **Step 2: Replace the incorrect line**

In `CLAUDE.md`, find:

```markdown
- **App data / metadata / DB:** `/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/`
```

Replace it with:

```markdown
- **App data / metadata / DB:** `/var/lib/plex/Plex Media Server/` — note `/var/lib/plex` is a
  **symlink to `/storage1/labdata/plex`**, so Plex's 383G of app data lives on the ZFS array, not
  the root disk. (`/var/lib/plexmediaserver/` does not exist.)
```

- [ ] **Step 3: Also correct the media library paths in the same section**

Find:

```markdown
- **Media libraries:** `/storage1/Media/{Movies,TV,Anime}` — same ZFS pool bind-mounted into the *arr containers.
```

Replace with:

```markdown
- **Media libraries:** `/storage1/{Movies,TV,Anime}` — `/storage1/Media/*` are symlinks to these.
  Same ZFS pool bind-mounted into the *arr containers.
```

- [ ] **Step 4: Verify no other stale Plex paths remain**

```bash
grep -rn "plexmediaserver/Library" . --include="*.md"
```

Expected: **no output**. If the string appears in `.claude/skills/` or `.agents/skills/`, fix
those too.

- [ ] **Step 5: Commit**

```bash
git add CLAUDE.md
git commit -m "docs: correct Plex data and library paths in CLAUDE.md

/var/lib/plexmediaserver does not exist; the real path is /var/lib/plex,
itself a symlink to /storage1/labdata/plex. Media libraries are
/storage1/{Movies,TV,Anime} with /storage1/Media/* as symlinks to them."
```

**PHASE 0 GATE:** Do not continue until `df -h /` shows at least 40G available and the
`valhalla root disk` Kuma monitor is green.

---

# PHASE 1 — Deploy the streaming stack

---

### Task 5: Create the host directory tree

Directories must exist and be owned by UID/GID 1000 **before** the containers start, or Jellyfin
will fail to write and the bind mounts will be created root-owned by Docker.

**Files:** none — live host operation.

- [ ] **Step 1: Create the directories**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "mkdir -p /storage1/labdata/jellyfin/{metadata,cache,trickplay,transcodes} && sudo mkdir -p /config/{jellyfin,jellystat,jellystat-db,wizarr} && sudo chown -R 1000:1000 /config/jellyfin /config/jellystat /config/wizarr /storage1/labdata/jellyfin && echo CREATED"
```

`/config/jellystat-db` is deliberately **not** chowned — the postgres image manages its own
ownership as UID 999.

- [ ] **Step 2: Verify ownership and placement**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "ls -ld /config/jellyfin /config/jellystat /config/wizarr /storage1/labdata/jellyfin/*; df -h /config/jellyfin /storage1/labdata/jellyfin | tail -3"
```

Expected: `/config/*` owned by `1000 1000` and on `/dev/sda2`; `/storage1/labdata/jellyfin/*`
owned by `1000 1000` and on `storage1` (virtiofs). **If the `/storage1` paths report `/dev/sda2`,
stop — `/storage1` is not mounted** and you would be writing into the placeholder directory that
caused the 2026-07-06 incident.

---

### Task 6: Write the streaming stack compose file

**Files:**
- Create: `stacks/streaming/docker-compose.yml`

- [ ] **Step 1: Generate the secrets you will need in Task 7**

```bash
echo "POSTGRES_PASSWORD=$(openssl rand -hex 24)"
echo "JWT_SECRET=$(openssl rand -hex 32)"
```

Keep this output — Task 7 pastes it into `stack.env`.

- [ ] **Step 2: Create `stacks/streaming/docker-compose.yml`**

```yaml
# streaming stack — Jellyfin and its satellites.
#
# Storage split is deliberate: SQLite config on the root SSD, all bulk data
# (metadata, trickplay, cache, transcodes) on /storage1. The root disk is only
# 194G and has filled twice; nothing here may grow unbounded on it.
#
# Trickplay gets an explicit sub-bind because Jellyfin 10.11 moved it to
# /config/data/trickplay and it is NOT relocatable from the UI.
#
# Transcodes are disk-backed, not tmpfs: jellyfin#16608 means Remux and
# DirectStream jobs finish before the segment cleaner's first check, orphaning
# segments. Plex already writes transcodes to virtiofs at a 48% transcode rate.
#
# Env convention: every service gets stack.env via env_file; var names there are
# exactly what the containers read. No ${VAR} interpolation, no Portainer UI
# env vars.

services:
  jellyfin:
    container_name: jellyfin
    image: lscr.io/linuxserver/jellyfin:latest
    restart: unless-stopped
    networks: [streaming, edge]
    env_file:

networks:

    external: true
```

- [ ] **Step 3: Verify the YAML parses**

```bash
docker compose -f stacks/streaming/docker-compose.yml config --quiet && echo "YAML OK"
```

Expected: `YAML OK`. A non-zero exit means a syntax error — fix before committing.

> If `stack.env` does not exist yet this may warn about a missing env file. Complete Task 7 and
> re-run this step.

---

### Task 7: Write the streaming stack environment file

**Files:**
- Create: `stacks/streaming/stack.env`

- [ ] **Step 1: Get the Plex token**

The token is in Plex's preferences on the host:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo grep -o 'PlexOnlineToken=\"[^\"]*\"' '/var/lib/plex/Plex Media Server/Preferences.xml'"
```

Expected: `PlexOnlineToken="xxxxxxxxxxxxxxxxxxxx"`. Record the value.

- [ ] **Step 2: Create `stacks/streaming/stack.env`**

Substitute the two secrets generated in Task 6 Step 1 and the Plex token from Step 1.
`JELLYFIN_TOKEN` is filled in later, in Task 16 — leave it as the empty placeholder for now.

```bash
# streaming stack config — injected into every service via env_file.
# Var names are exactly what the containers read; no ${VAR} interpolation,
# no Portainer UI env vars needed.

# --- shared ---
TZ=America/Chicago
PUID=1000
PGID=1000

# --- jellystat-db (postgres:16-alpine) ---
POSTGRES_DB=jfstat
POSTGRES_USER=jellystat
POSTGRES_PASSWORD=REPLACE_WITH_GENERATED_POSTGRES_PASSWORD

# --- jellystat ---
POSTGRES_IP=jellystat-db
POSTGRES_PORT=5432
JWT_SECRET=REPLACE_WITH_GENERATED_JWT_SECRET

# --- jellyplex-watched ---
# Plex is host-native, not containerised, so it is reached on the LAN IP.
PLEX_URL=http://192.168.1.69:32400
PLEX_TOKEN=REPLACE_WITH_PLEX_TOKEN
JELLYFIN_BASEURL=http://jellyfin:8096
JELLYFIN_TOKEN=
SYNC_FROM_PLEX_TO_JELLYFIN=True
SYNC_FROM_JELLYFIN_TO_PLEX=True
# Start in dry-run. Task 16 flips this to False after the mapping is verified.
DRYRUN=True
SLEEP_DURATION=21600
LOG_LEVEL=INFO
```

- [ ] **Step 3: Verify LF line endings**

CRLF in `stack.env` appends `\r` to every value and breaks containers in ways that are very hard
to diagnose.

```bash
file stacks/streaming/stack.env
```

Expected: `ASCII text` — **not** `ASCII text, with CRLF line terminators`. If it reports CRLF:

```bash
git add --renormalize stacks/streaming/stack.env
```

- [ ] **Step 4: Verify the compose file now resolves cleanly**

```bash
docker compose -f stacks/streaming/docker-compose.yml config --quiet && echo "COMPOSE OK"
```

Expected: `COMPOSE OK`.

- [ ] **Step 5: Verify Portainer UI env compliance**

```bash
pwsh -File scripts/check-portainer-stack-env.ps1
```

Expected: no failures reported for `streaming`. This script exists to catch the exact mistake of
leaving UI environment variables set.

- [ ] **Step 6: Commit**

```bash
git add stacks/streaming/docker-compose.yml stacks/streaming/stack.env
git commit -m "feat(streaming): add jellyfin stack

New Portainer stack: jellyfin, jellystat + postgres, wizarr and
jellyplex-watched. Bulk data (metadata, trickplay, cache, transcodes)
binds to /storage1; only SQLite config lands on the root disk.

Trickplay gets an explicit sub-bind because 10.11 moved it to
/config/data/trickplay, which is not relocatable from the UI. Transcodes
are disk-backed rather than tmpfs because jellyfin#16608 orphans segments
on the Remux/DirectStream jobs that are routine on this server."
```

---

### Task 8: Add the Caddy site blocks

**Files:**
- Modify: `Caddyfile`

`jellyfin` and `wizarr` are **public** — remote users and invite recipients reach them from
anywhere, which is the entire point of leaving Plex. `jellystat` is internal-only and follows the
existing tautulli pattern exactly.

> Note the `internal_gate` vs `internal_only` distinction: inside a `route {}` block you **must**
> use `internal_gate`, because Caddy sorts `route` ahead of `respond` and an `import internal_only`
> above a catch-all route is dead code. This repo already had to fix that on nine sites.

- [ ] **Step 1: Add the public streaming blocks**

Insert after the `requests.ginnoir.com` block (around line 134):

```caddy
# =============================================================
# STREAMING — public (replaces Plex's own remote access)
# =============================================================
jellyfin.ginnoir.com {
	reverse_proxy jellyfin:8096
}

wizarr.ginnoir.com {
	reverse_proxy wizarr:5690
}
```

- [ ] **Step 2: Add the internal-only stats block**

Insert immediately after the `tautulli.ginnoir.com` block (around line 205):

```caddy
jellystat.ginnoir.com {
	route {
		import internal_gate
		import authentik_outpost
		handle {
			import authentik_forward_auth
			reverse_proxy jellystat:3000
		}
	}
}
```

- [ ] **Step 3: Validate the Caddyfile before pushing**

```bash
docker run --rm -v "${PWD}/Caddyfile:/etc/caddy/Caddyfile:ro" caddy:latest caddy validate --config /etc/caddy/Caddyfile --adapter caddyfile
```

Expected: `Valid configuration`.

> This will warn about the `cloudflare` DNS module being unknown — that module is baked into the
> custom Caddy image on valhalla, not the stock one. Warnings about `acme_dns cloudflare` are
> expected and safe. Any **structural** error is not.

- [ ] **Step 4: Commit**

```bash
git add Caddyfile
git commit -m "feat(caddy): add jellyfin, wizarr and jellystat sites

jellyfin and wizarr are public by design — they replace Plex's own
remote access. jellystat is internal_gate + forward_auth, matching the
tautulli pattern."
```

---

### Task 9: Register the stack in Portainer and deploy

New stacks must be registered in Portainer once, by hand. After that, git-polling handles every
subsequent change.

**Files:** none — push and UI operation.

- [ ] **Step 1: Push everything so far**

```bash
git push origin main
```

This makes the stack files visible to Portainer. **Caddy reloads on this push too** — the Gitea
Actions runner copies the Caddyfile and runs `caddy reload`. The three new sites will 502 until
the containers exist, which is expected and harmless.

- [ ] **Step 2: Register the stack**

In the Portainer UI at `https://portainer.ginnoir.com`:
1. **Stacks → Add stack**
2. Name: `streaming`
3. Build method: **Repository**
4. Repository URL: `https://gitea.ginnoir.com/ginnoir/homelabstack`
5. Repository reference: `refs/heads/main`
6. Compose path: `stacks/streaming/docker-compose.yml`
7. **Authentication: on.** Use the fine-grained Gitea PAT that the other stacks use — the runner
   PAT cannot clone.
8. **GitOps updates: on**, Mechanism **Polling**, Interval `5m`
9. **Environment variables: leave completely empty.** This is enforced by
   `scripts/check-portainer-stack-env.ps1`.
10. **Deploy the stack**

> Known quirk: the create call may appear to time out while actually succeeding. If it does, do
> **not** retry — refresh the stack list and confirm `streaming` is present before doing anything
> else, or you will create a duplicate.

- [ ] **Step 3: Verify all five containers are running**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker ps --filter label=com.docker.compose.project=streaming --format 'table {{.Names}}\t{{.Status}}'"
```

Expected: five rows — `jellyfin`, `jellystat`, `jellystat-db`, `wizarr`, `jellyplex-watched` —
all `Up`.

`jellyplex-watched` may show as restarting or exited: it has no Jellyfin token yet and is in
dry-run. That is expected until Task 16.

- [ ] **Step 4: Verify Jellyfin is serving**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "curl -s -o /dev/null -w '%{http_code}\n' http://localhost:8096/health"
```

Expected: `200`.

- [ ] **Step 5: Verify the bind mounts landed where intended**

This is the single most important verification in Phase 1. If trickplay or transcodes end up on
the root disk, the disk will fill again.

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker inspect jellyfin --format '{{range .Mounts}}{{.Source}} -> {{.Destination}} ({{.Mode}}){{\"\n\"}}{{end}}'"
```

Expected, exactly these sources:
- `/config/jellyfin -> /config`
- `/storage1/labdata/jellyfin/metadata -> /config/metadata`
- `/storage1/labdata/jellyfin/cache -> /config/cache`
- `/storage1/labdata/jellyfin/trickplay -> /config/data/trickplay`
- `/storage1/labdata/jellyfin/transcodes -> /transcode`
- `/storage1/Movies -> /data/movies (ro)`
- `/storage1/TV -> /data/tv (ro)`
- `/storage1/Anime -> /data/anime (ro)`

The three library mounts **must** show `ro`.

- [ ] **Step 6: Verify the public site resolves over HTTPS**

```bash
curl -s -o /dev/null -w '%{http_code}\n' https://jellyfin.ginnoir.com/health
```

Expected: `200`. If you get a TLS error, check that the certificate issued — DNS-01 renewals on
this host have failed before when the split-horizon override shadowed the SOA record. The canary:

```bash
dig +short SOA ginnoir.com @192.168.1.1
```

Expected: a real SOA record, not empty.

---

### Task 10: Complete Jellyfin setup and add libraries

**Files:** none — UI operation.

- [ ] **Step 1: Run the setup wizard**

Browse to `https://jellyfin.ginnoir.com`. On the wizard:
1. Preferred display language: English
2. Create the admin account. **Use a strong, unique password** — this server is publicly
   reachable and Plex's relay is no longer hiding it.
3. Skip adding libraries here; Step 2 does it with the right settings.
4. Set metadata language / country
5. **Allow remote connections: yes.** Leave automatic port mapping **off** — Caddy handles ingress.

- [ ] **Step 2: Add the three libraries**

Dashboard → Libraries → Add Media Library. Create each with these settings:

| Setting | Movies | TV | Anime |
|---|---|---|---|
| Content type | Movies | Shows | Shows |
| Display name | `Movies` | `TV` | `Anime` |
| Folder | `/data/movies` | `/data/tv` | `/data/anime` |
| Preferred metadata language | English | English | English |

For **all three**, in the library settings:
- **Enable "Save artwork into media folders": OFF**. The library mounts are read-only, and
  leaving this on generates a stream of write errors in the logs.
- **"Enable trickplay image extraction": OFF for now.** Task 13 turns it on deliberately, after
  the thread cap is configured. Leaving it on here starts an uncapped multi-day job that will
  compete with the initial scan.

For **Anime only**, additionally set metadata downloaders to prefer **AniDB** and **AniList**
above TheMovieDb (these plugins are installed in Task 14 — revisit this after that task).

- [ ] **Step 3: Trigger and watch the initial scan**

Dashboard → Scheduled Tasks → **Scan Media Library** → Run.

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker logs --tail 40 jellyfin"
```

- [ ] **Step 4: Verify item counts against Plex**

Once the scan completes (expect a few hours for ~1891 items), check Dashboard → Libraries.

Expected, approximately:
- Movies: **~1357**
- TV: **~173 series**
- Anime: **~361 series**

A shortfall over ~2% means naming problems worth investigating before you build anything on top
of this library.

- [ ] **Step 5: Verify nothing significant landed on the root disk**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "df -h / | tail -1; sudo du -sh /config/jellyfin; du -sh /storage1/labdata/jellyfin/*"
```

Expected: `/config/jellyfin` in the low **hundreds of MB to a few GB** (SQLite only), with
`metadata` on `/storage1` holding the artwork. If `/config/jellyfin` is tens of GB, a bind mount
is wrong — go back to Task 9 Step 5.

- [ ] **Step 6: Regenerate the bookmark files**

```bash
pwsh -File scripts/gen-bookmarks.ps1
git add bookmarks-domains.html bookmarks-ports.html
git commit -m "chore: regenerate bookmarks for streaming stack"
git push origin main
```

---

# PHASE 2 — Parity with Plex

---

### Task 11: Install Plexyfin and import curated artwork and collections

Plexyfin is the only reason any of Plex's 383G is worth reading. It copies the curated **15G**
`Metadata` investment — posters, backdrops and collections — directly from the live PMS API.

**This plugin is destructive.** It deletes and replaces artwork wholesale on every run. It is
installed, run once, and then removed.

**Files:** none — UI operation against the live Plex API.

- [ ] **Step 1: Confirm Plex is still running and reachable**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "systemctl is-active plexmediaserver; curl -s -o /dev/null -w '%{http_code}\n' 'http://192.168.1.69:32400/identity'"
```

Expected: `active` and `200`. Everything in this task reads from the live Plex server.

- [ ] **Step 2: Add the Plexyfin repository**

Jellyfin Dashboard → Plugins → Repositories → **Add**:
- Repository Name: `Plexyfin`
- Repository URL: `https://raw.githubusercontent.com/cleverdevil/plexyfin/main/metadata/stable/manifest.json`

- [ ] **Step 3: Install and restart**

Dashboard → Plugins → Catalog → **Plexyfin** → Install. Then restart Jellyfin:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker restart jellyfin && sleep 20 && curl -s -o /dev/null -w '%{http_code}\n' http://localhost:8096/health"
```

Expected: `200`.

- [ ] **Step 4: Configure Plexyfin**

Dashboard → Plugins → Plexyfin:
- Plex Server URL: `http://192.168.1.69:32400`
- Plex Token: the token recorded in Task 7 Step 1
- Enable **Sync Collections**
- Enable **Sync Artwork**
- Save

- [ ] **Step 5: Run the sync**

Use the plugin's **Sync Now** button, then watch:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker logs --tail 60 -f jellyfin"
```

Expected: progress lines naming collections and items. Let it finish completely — interrupting
leaves artwork half-replaced.

- [ ] **Step 6: Verify collections and artwork arrived**

In the Jellyfin web UI:
- Movies → Collections shows your Plex collections
- Spot-check five movies where you know you set custom posters in Plex; confirm the poster
  matches Plex, not TMDB's default

- [ ] **Step 7: Remove the plugin**

This is not optional. Left installed, it will destroy any artwork you later customise in
Jellyfin.

Dashboard → Plugins → Plexyfin → **Uninstall**. Then Dashboard → Plugins → Repositories →
remove the `Plexyfin` repository. Restart Jellyfin:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker restart jellyfin && sleep 20 && curl -s -o /dev/null -w '%{http_code}\n' http://localhost:8096/health"
```

Expected: `200`.

- [ ] **Step 8: Verify it is gone**

Dashboard → Plugins → My Plugins. Expected: **Plexyfin is not listed.**

---

### Task 12: Configure transcoding — NVDEC decode, CPU encode, segment cleanup

The P100 cannot encode — GP100 has no NVENC — so this does nothing for live streaming transcode.
It exists for one reason: **trickplay generation in Task 13 is decode-plus-JPEG-encode**, and
NVDEC accelerates exactly that.

**Files:**
- Modify: `stacks/streaming/docker-compose.yml`

- [ ] **Step 1: Check whether llama-swap currently holds the GPU**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "nvidia-smi --query-compute-apps=pid,process_name,used_memory --format=csv"
```

If a llama-swap process holds most of the 16G, either wait for it to idle or accept that
trickplay generation will be slower. Note what you found.

- [ ] **Step 2: Add the CDI device to the jellyfin service**

In `stacks/streaming/docker-compose.yml`, inside the `jellyfin` service, add after `env_file`:

```yaml
    devices:
      - nvidia.com/gpu=0
```

- [ ] **Step 3: Commit and push**

```bash
git add stacks/streaming/docker-compose.yml
git commit -m "feat(streaming): give jellyfin CDI access to the P100

Decode only — GP100 has no NVENC. This is for trickplay generation,
which is decode plus JPEG encode."
git push origin main
```

- [ ] **Step 4: Wait for the redeploy, then verify the GPU is visible in the container**

Portainer polls every 5 minutes. Then:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker exec jellyfin nvidia-smi -L"
```

Expected: `GPU 0: Tesla P100-PCIE-16GB (UUID: GPU-f23318db-...)`.

**If this errors**, the CDI device name is wrong. Check the available names and correct the
compose file:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "grep -E '^\s+name:' /etc/cdi/nvidia.yaml"
```

- [ ] **Step 5: Enable NVDEC in Jellyfin**

Dashboard → Playback → Transcoding:
- Hardware acceleration: **NVIDIA NVENC**
- Enable hardware decoding for: **H264**, **HEVC**, **VP9**
- **Leave "Enable hardware encoding" UNCHECKED.** The P100 cannot encode; ticking this makes
  every transcode fail.
- Save

- [ ] **Step 5a: Configure the CPU encoder and segment cleanup**

On the same Dashboard → Playback → Transcoding page, since encoding is CPU-bound:

- **Encoding preset: `veryfast`.** The default is slower and this host has no encode offload.
- **Transcode thread count: `8`.** Per session. With a measured peak of 7 concurrent streams,
  this bounds the worst case at 56 of 52 threads — deliberately just over-subscribed rather than
  unbounded, which is what the default does.
- **Enable throttling: ON.** Pauses ffmpeg once it runs far enough ahead of the player.
- **Enable segment deletion: ON.**
- **Segment keep seconds: `360`.**
- Save

Segment deletion matters more here than it does on most servers. Per
[jellyfin#16608](https://github.com/jellyfin/jellyfin/issues/16608), the cleaner's first check is
at 20 seconds and the throttler's at 5, but Remux and DirectStream jobs finish in 2-7 seconds —
so on those, neither ever fires. DirectStream (copy video + transcode audio) was **8 of 25**
sampled sessions on this server. This setting does not fix that bug; it bounds the damage on
every *other* job type. The transcode directory is on `/storage1` precisely because this bug
cannot be configured away.

- [ ] **Step 5b: Verify orphaned segments are actually being cleaned**

Play something that transcodes, let it run two minutes, stop it, wait five minutes, then:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "du -sh /storage1/labdata/jellyfin/transcodes; ls /storage1/labdata/jellyfin/transcodes | wc -l"
```

Expected: small size and a low file count. If this directory grows monotonically over the
following days, add a weekly systemd timer to prune files older than 24 hours — the same pattern
as Task 3's timer.

- [ ] **Step 6: Verify a decode actually uses the GPU**

Play a HEVC file that requires transcoding, from the web client, then:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "nvidia-smi --query-compute-apps=pid,process_name,used_memory --format=csv | grep -i ffmpeg || echo 'no ffmpeg on GPU'"
```

Expected: an `ffmpeg` process listed. If you see `no ffmpeg on GPU`, decoding fell back to CPU —
check Dashboard → Playback logs for the reason. This is not fatal; it only makes Task 13 slower.

---

### Task 13: Generate trickplay

Plex's 365G of BIF preview thumbnails is **format-incompatible** with Jellyfin's tiled JPEG
trickplay. None of it is reusable. Budget **300-400G on `/storage1`** and a multi-day first pass
over ~1891 items.

**Files:** none — UI operation plus monitoring.

- [ ] **Step 1: Confirm you have the disk headroom**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "df -h /storage1 | tail -1"
```

Expected: **at least 1T available**. At plan time there was 17T, so this is a formality — but
confirm, because this task writes hundreds of gigabytes.

- [ ] **Step 2: Configure trickplay with a thread cap**

Dashboard → Playback → Trickplay:
- Enable trickplay image extraction **during library scan**: **ON**
- **Thread count: `20`.** The host has 52 threads. Leaving this at the default (all cores) starves
  live transcoding, which is the thing users actually notice.
- Interval: `10000` ms (the default)
- Width resolutions: `320` (the default)
- Enable hardware decoding: **ON** (this is what Task 12 was for)
- Save

- [ ] **Step 3: Enable trickplay on each library**

Dashboard → Libraries. For each of Movies, TV and Anime, edit the library and tick **Enable
trickplay image extraction**. (These were deliberately left off in Task 10 Step 2.)

- [ ] **Step 4: Start generation**

Dashboard → Scheduled Tasks → **Generate Trickplay Images** → Run.

- [ ] **Step 5: Monitor progress and disk growth**

Check periodically over the following days:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "du -sh /storage1/labdata/jellyfin/trickplay; df -h /storage1 | tail -1; uptime"
```

Expected: `trickplay` growing steadily toward the 300-400G range; `/storage1` avail falling
correspondingly; load average high but the host responsive.

**Abort condition:** if `/storage1` available space drops below **500G**, stop the scheduled task
immediately and reassess — do not let this fill the array.

- [ ] **Step 6: Verify trickplay works in a client**

Once the task reports complete, open any movie in the web client and scrub the timeline.
Expected: preview thumbnails appear above the scrubber.

- [ ] **Step 7: Confirm nothing leaked onto the root disk**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "df -h / | tail -1; sudo du -sh /config/jellyfin"
```

Expected: root disk essentially unchanged from Task 10. If it grew by tens of GB, the trickplay
sub-bind is not working — stop and fix it.

---

### Task 14: Install the remaining plugins

**Files:** none — UI operation.

- [ ] **Step 1: Install Intro Skipper**

The original plugin is unmaintained; use the maintained fork. **Verify 10.11 compatibility before
installing** — this plugin patches the web player and a version mismatch breaks playback.

1. Check the fork's README for a stated 10.11 compatible release:
   `https://github.com/Bobby306/intro-skipper`
2. If, and only if, it declares 10.11 support, add its repository under
   Dashboard → Plugins → Repositories using the manifest URL from its README, then install.
3. If it does **not** declare 10.11 support, **skip this plugin** and note it here. It is optional
   polish, not a migration requirement.

- [ ] **Step 2: Install the anime metadata plugins**

Dashboard → Plugins → Catalog. Install from the official catalogue:
- **AniDB**
- **AniList**

- [ ] **Step 3: Restart and verify**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker restart jellyfin && sleep 25 && curl -s -o /dev/null -w '%{http_code}\n' http://localhost:8096/health"
```

Expected: `200`.

- [ ] **Step 4: Point the Anime library at the anime providers**

Dashboard → Libraries → Anime → edit. Under metadata downloaders, drag **AniDB** and **AniList**
above **TheMovieDb**. Save, then run **Scan Media Library** limited to the Anime library.

- [ ] **Step 5: Verify anime metadata improved**

Spot-check five anime series. Expected: correct season/episode numbering and Japanese-release
metadata rather than TMDB's Western groupings.

> **Do not install:** `jellyfin-plugin-sso` (browser-only OIDC — Roku, Fire TV and tvOS cannot use
> it, and those are the entire user base), Open Subtitles (Bazarr already writes subtitles to disk
> and does it better), Playback Reporting (Jellystat supersedes it).

---

### Task 15: Connect Sonarr, Radarr and Bazarr to Jellyfin

New imports must refresh Jellyfin the way they currently refresh Plex. **Leave the existing Plex
connections in place** — both servers stay live until Task 22.

**Files:** none — UI operation.

- [ ] **Step 1: Create a Jellyfin API key**

Jellyfin Dashboard → API Keys → **New API Key**, name it `arr-integration`. Copy the key.

Record it here — Task 16 needs a Jellyfin key too, and you can reuse this one:

```
JELLYFIN_API_KEY = ____________________
```

- [ ] **Step 2: Add the connection in Sonarr**

At `https://sonarr.ginnoir.com` → Settings → Connect → **+** → **Emby / Jellyfin**:
- Name: `Jellyfin`
- Host: `jellyfin`
- Port: `8096`
- API Key: the key from Step 1
- Enable **On Import**, **On Upgrade**, **On Rename**, **On Series Delete**
- Update Library: **on**
- **Test**, then Save

Expected: the Test button returns success. A failure here usually means the containers cannot see
each other — both are on `edge`, so check that first.

- [ ] **Step 3: Add the connection in Radarr**

At `https://radarr.ginnoir.com` → Settings → Connect → **+** → **Emby / Jellyfin**. Same host,
port and key. Enable **On Import**, **On Upgrade**, **On Rename**, **On Movie Delete**. Test and
Save.

- [ ] **Step 4: Add the connection in Bazarr**

At `https://bazarr.ginnoir.com` → Settings → Subtitles → enable the Jellyfin/Emby integration
with the same host, port and key, so subtitle downloads trigger a refresh.

- [ ] **Step 5: Verify end to end**

Trigger a rename or manual import in Radarr on a single film, then:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker logs --tail 30 jellyfin | grep -i 'refresh\|library'"
```

Expected: a library refresh entry appearing within a minute of the Radarr action.

---

# PHASE 3 — Watch-state sync

---

### Task 16: Bring up two-way watch history sync

JellyPlex-Watched matches items by filename and provider IDs. It is good but not perfect, so this
task runs it in dry-run first and only enables writes once the mapping is confirmed.

**Files:**
- Modify: `stacks/streaming/stack.env`

- [ ] **Step 1: Fill in the Jellyfin token**

In `stacks/streaming/stack.env`, set `JELLYFIN_TOKEN` to the API key recorded in Task 15 Step 1.
Leave `DRYRUN=True` for now.

- [ ] **Step 2: Commit, push and wait for the redeploy**

```bash
git add stacks/streaming/stack.env
git commit -m "feat(streaming): give jellyplex-watched its jellyfin token"
git push origin main
```

Portainer redeploys within 5 minutes.

- [ ] **Step 3: Run a dry-run and read the output carefully**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker restart jellyplex-watched && sleep 90 && docker logs --tail 120 jellyplex-watched"
```

Expected: it connects to both servers, lists users, and reports what it *would* sync. **Nothing is
written in dry-run.**

- [ ] **Step 4: Check for username mismatches**

In the dry-run output, look for users present on one server but not the other. Plex usernames and
Jellyfin usernames will not match for anyone who chose a different name at signup.

If there are mismatches, add a mapping to `stacks/streaming/stack.env` using the tool's
`USER_MAPPING` format — a JSON object of `plex_username: jellyfin_username`:

```bash
USER_MAPPING={"plexname1": "jellyfinname1", "plexname2": "jellyfinname2"}
```

Commit, push, wait for redeploy, and re-run Step 3 until the mapping is clean.

> Early on only your own account exists in Jellyfin, so most Plex users will legitimately have no
> counterpart. That is expected — this mapping gets revisited as people are onboarded in Task 19.

- [ ] **Step 5: Verify your own account's history would sync correctly**

In the dry-run output, find your own user. Expected: a plausible list of watched items matching
what you know you have watched in Plex. If it reports zero for a library you have definitely
watched from, path matching is failing — diagnose before enabling writes.

- [ ] **Step 6: Enable writes**

In `stacks/streaming/stack.env`:

```bash
DRYRUN=False
```

```bash
git add stacks/streaming/stack.env
git commit -m "feat(streaming): enable jellyplex-watched writes after dry-run verification"
git push origin main
```

- [ ] **Step 7: Verify a real sync round-trip**

After the redeploy, mark an episode watched **in Jellyfin** that is unwatched in Plex. Then:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker restart jellyplex-watched && sleep 120 && docker logs --tail 60 jellyplex-watched"
```

Check Plex: the episode should now be watched there too. Then do the reverse — mark something
watched in Plex and confirm it appears in Jellyfin after the next cycle.

Expected: both directions work. `SLEEP_DURATION=21600` means it runs every 6 hours from here on.

**PHASE 3 GATE:** Jellyfin is now at parity with Plex, with two-way history sync. Everything
after this point involves other people.

---

# PHASE 4 — Pilot

---

### Task 17: Configure Wizarr

Per the design decision, invites are issued **manually and selectively**. Most Plex users are
dormant. There is no bulk invite generation and no scripted account creation in this plan.

**Files:** none — UI operation.

- [ ] **Step 1: Complete Wizarr setup**

Browse to `https://wizarr.ginnoir.com` and create the admin account.

- [ ] **Step 2: Connect it to Jellyfin**

In Wizarr settings, add a media server:
- Type: **Jellyfin**
- URL: `http://jellyfin:8096`
- API Key: the key from Task 15 Step 1

- [ ] **Step 3: Restrict which libraries invited users get**

Grant **Movies**, **TV** and **Anime**. Nothing else exists, but set this explicitly so future
libraries are not exposed by default.

- [ ] **Step 4: Customise the onboarding wizard**

Configure the post-invite steps to cover the three platforms that matter here — Roku, Fire TV /
Android TV, and Apple TV / iOS — with the app store link for each. These account for the
overwhelming majority of real playback.

- [ ] **Step 5: Verify with a throwaway invite**

Create an invite, open it in a private browser window, and complete the flow with a test account.

Expected: the account appears in Jellyfin Dashboard → Users with only the three libraries granted.
Delete the test account from both Wizarr and Jellyfin afterwards.

---

### Task 18: Pilot with real users

**Files:** none — human process.

- [ ] **Step 1: Pick 3-5 willing users covering every platform**

You need **at least one each on Roku, Fire TV / Android TV, and Apple TV / iOS**. Platform
coverage matters more than user count — a pilot of five Android users tells you nothing about
Roku.

- [ ] **Step 2: Send each an individual Wizarr invite**

- [ ] **Step 3: Add their username mappings to jellyplex-watched**

As each pilot user creates their Jellyfin account, add their Plex→Jellyfin mapping to
`USER_MAPPING` in `stacks/streaming/stack.env` (see Task 16 Step 4), then commit and push. Their
history then syncs both ways and they can move between servers freely.

- [ ] **Step 4: Collect feedback on the three things that actually break**

Ask each pilot user specifically about: playback start time, whether anything stutters mid-stream,
and whether the onboarding wizard was followable. Vague "is it working?" gets vague answers.

- [ ] **Step 5: Verify transcode behaviour under real load**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker exec jellyfin ps aux | grep -c '[f]fmpeg'; uptime"
```

Run this while pilot users are actually watching. Expected: load average well under 52.

- [ ] **Step 6: Record the pilot outcome**

Note per platform whether playback worked, and any transcoding observations. This is the input to
the Task 20 hardware decision.

---

# PHASE 5 — Selective migration

---

### Task 19: Onboard users on demand

**Files:** none — human process, ongoing.

- [ ] **Step 1: Write a short explainer to accompany invites**

One that answers, in plain language: why the change is happening, what to install on their device,
that their watch history carries over, and that Plex keeps working until an announced date.

**This is sent with an invite, not broadcast.** Save it somewhere you can paste from.

- [ ] **Step 2: Issue invites individually as people ask or as you choose**

Dormant accounts get nothing. There is no campaign and no deadline pressure at this stage.

- [ ] **Step 3: Keep the user mapping current**

Each time someone joins, add their Plex→Jellyfin mapping to `USER_MAPPING` in
`stacks/streaming/stack.env`, then commit and push. Without this their history does not follow
them.

- [ ] **Step 4: Let it run at least 4 weeks**

This is a **hard gate on elapsed time**, not on effort. Jellystat needs a meaningful sample before
the Task 20 decision can be made on evidence rather than vibes. Both servers stay live throughout.

---

### Task 20: Decide the transcoding hardware question

**Files:** none — analysis and a decision.

- [ ] **Step 1: Set up Jellystat**

Browse to `https://jellystat.ginnoir.com` (Authentik will challenge you first, and it is LAN or
tailnet only). Create the admin account and connect it to Jellyfin at `http://jellyfin:8096` with
the API key from Task 15.

> Do this at the **start** of the 4-week window in Task 19, not the end, or it will have nothing
> to report.

- [ ] **Step 2: Pull the numbers after 4 weeks**

From Jellystat, record: peak concurrent streams, the direct-play vs transcode ratio, and the most
common transcode reasons.

- [ ] **Step 3: Compare against the Plex baseline**

The measured Plex baseline was: **48% transcode, peak 7 concurrent, 1080p SDR, no subtitle burn-in,
no HDR tone-mapping**.

Jellyfin's Android client direct-plays audio codecs Plex's refuses, and Android was the heaviest
platform at 281 plays — so the transcode rate may well have **fallen**.

- [ ] **Step 4: Check whether the CPU actually struggled**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "uptime; sudo journalctl -u docker --since '4 weeks ago' | grep -ci 'jellyfin.*oom' || echo 'no OOM events'"
```

Also ask users directly whether playback ever stuttered or failed to start. User reports beat
graphs here.

- [ ] **Step 5: Make and record the decision**

- **If load is comfortable:** do nothing. Record that CPU-only transcoding was sufficient and
  close this task.
- **If the CPU is straining:** buy an **Intel Arc A310 or A380** (~$100-150). No session limit,
  AV1, full encode plus decode. This requires a PCIe slot, an R730XD shutdown, and an IOMMU
  passthrough to the valhalla VM. **Check the new card's IOMMU group before buying** — only the
  P100's group 7 is known clean. Write that up as its own plan; it is not a step in this one.

---

# PHASE 6 — Cutover

---

### Task 21: Convert Seerr from Plex to Jellyfin

`seerr-team/seerr` supports Jellyfin natively, but converting an existing Plex-configured install
is **unsupported upstream** ([seerr#2522](https://github.com/seerr-team/seerr/issues/2522), open).
Hence the backup first and the documented fallback.

**Files:** none — live operation.

- [ ] **Step 1: Back up the Seerr configuration**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo tar czf /storage1/labdata/seerr-preJellyfin-$(date +%Y%m%d).tar.gz -C /config overseerr && ls -lh /storage1/labdata/seerr-preJellyfin-*.tar.gz"
```

Expected: a tarball listed with a non-trivial size. **Do not proceed without this.**

- [ ] **Step 2: Attempt the in-place conversion**

At `https://requests.ginnoir.com` → Settings → General, change the media server to **Jellyfin**:
- Hostname: `jellyfin`
- Port: `8096`
- API key: the key from Task 15 Step 1
- Save, then Settings → Jellyfin → **Sync Libraries** and enable Movies, TV and Anime

- [ ] **Step 3: Verify it works**

Expected: libraries sync, existing media shows as **Available**, and a test request routes to
Radarr or Sonarr correctly.

- [ ] **Step 4: If the conversion failed, use the fallback**

Stop Seerr, move the config aside, and start fresh:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker stop seerr && sudo mv /config/overseerr /config/overseerr.plex-era && sudo mkdir -p /config/overseerr && sudo chown 1000:1000 /config/overseerr && docker start seerr"
```

Then reconfigure from scratch at `https://requests.ginnoir.com`: Jellyfin as the media server,
then re-add Radarr and Sonarr with their API keys. **Request history is lost** — this was an
accepted trade-off in the design.

- [ ] **Step 5: Verify user login**

Have one migrated user sign in to Seerr with their Jellyfin credentials and submit a request.
Expected: the request appears in Radarr or Sonarr.

---

### Task 22: Identify holdouts and cut the Plex integrations

**Files:** none — analysis plus UI operations.

- [ ] **Step 1: Find who is still on Plex and on what**

```bash
ssh -o BatchMode=yes ginnoir@valhalla 'KEY=$(grep -E "^api_key" /config/tautulli/config.ini | head -1 | sed "s/.*= *//"); curl -s "http://localhost:8181/api/v2?apikey=$KEY&cmd=get_history&length=300" | python3 -c "
import sys,json,collections
d=json.load(sys.stdin)[\"response\"][\"data\"][\"data\"]
c=collections.Counter((r.get(\"friendly_name\"),r.get(\"platform\")) for r in d)
for k,v in c.most_common(30): print(f\"{v:5d}  {k[0]:24s} {k[1]}\")
"'
```

Expected: a short list. Anyone with a meaningful play count is someone to contact in Step 2.

- [ ] **Step 2: Contact each remaining active user individually**

Expected pattern from the baseline: a small number of stragglers, plus **Tizen (Samsung TV)** and
**PlayStation** users — 3 plays out of 600 at plan time.

- Tizen: point them at the Moonfin client, or a $30 Fire TV / Google TV stick
- PlayStation: there is **no native Jellyfin app**. Offer the same streaming-stick suggestion.

- [ ] **Step 3: Announce the Plex end date**

Give at least two weeks' notice to everyone still active on Plex.

- [ ] **Step 4: Remove the Plex connections from the *arrs**

- Sonarr → Settings → Connect → delete the **Plex** connection
- Radarr → Settings → Connect → delete the **Plex** connection
- Bazarr → Settings → disable the Plex integration

Leave the Jellyfin connections from Task 15 in place.

- [ ] **Step 5: Verify imports still trigger Jellyfin refreshes**

Trigger a rename in Radarr, then:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker logs --tail 30 jellyfin | grep -i 'refresh\|library'"
```

Expected: a refresh entry. Nothing should have broken by removing the Plex connections.

---

# PHASE 7 — Decommission

---

### Task 23: Stop Plex and soak

**Files:** none — live operation.

- [ ] **Step 1: Final watch-state sync while Plex is still running**

This is the last chance to capture anything watched on Plex. JellyPlex-Watched needs the live PMS
API.

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker restart jellyplex-watched && sleep 180 && docker logs --tail 80 jellyplex-watched"
```

Expected: a clean sync with no errors.

- [ ] **Step 2: Stop and disable the service**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo systemctl stop plexmediaserver && sudo systemctl disable plexmediaserver && systemctl is-active plexmediaserver; systemctl is-enabled plexmediaserver"
```

Expected: `inactive` and `disabled`.

- [ ] **Step 3: Stop the sync container**

With Plex down, JellyPlex-Watched has nothing to talk to and will log errors forever.

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker stop jellyplex-watched"
```

- [ ] **Step 4: Soak for two weeks**

The package and all 383G of data remain on disk. **Rollback during this window is a single
command** (`sudo systemctl start plexmediaserver`).

Do not proceed to Task 24 until two weeks have passed with no one asking for Plex back.

---

### Task 24: Remove Plex and reclaim its storage

**Files:**
- Modify: `stacks/streaming/docker-compose.yml` (remove `jellyplex-watched`)
- Modify: `stacks/media/docker-compose.yml` (remove `tautulli`)
- Modify: `Caddyfile` (remove the `tautulli` site block)

- [ ] **Step 1: Archive the Plex data before removing anything**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo tar czf /storage1/labdata/plex-final-$(date +%Y%m%d).tar.gz -C /storage1/labdata plex && ls -lh /storage1/labdata/plex-final-*.tar.gz"
```

This takes a long time — 383G of mostly-incompressible thumbnails. Expected: a tarball of roughly
300G+. **Keep it 30 days.** Set a calendar reminder to delete it.

- [ ] **Step 2: Remove the package**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo pacman -Rns --noconfirm plex-media-server && which plexmediaserver || echo 'plex removed'"
```

Expected: `plex removed`.

- [ ] **Step 3: Reclaim the data directory**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "df -h /storage1 | tail -1 && sudo rm -rf /storage1/labdata/plex && sudo rm -f /var/lib/plex && df -h /storage1 | tail -1"
```

Expected: `/storage1` available space increases by roughly **383G**.

- [ ] **Step 4: Remove jellyplex-watched from the compose file**

In `stacks/streaming/docker-compose.yml`, delete the entire `jellyplex-watched` service block. It
has no purpose without Plex.

Also remove these now-dead lines from `stacks/streaming/stack.env`:

```
PLEX_URL, PLEX_TOKEN, JELLYFIN_BASEURL, JELLYFIN_TOKEN,
SYNC_FROM_PLEX_TO_JELLYFIN, SYNC_FROM_JELLYFIN_TO_PLEX,
DRYRUN, SLEEP_DURATION, USER_MAPPING
```

Keep `TZ`, `PUID`, `PGID`, and every `POSTGRES_*` and `JWT_SECRET` value.

- [ ] **Step 5: Remove Tautulli**

Tautulli is Plex-only and now monitors nothing. In `stacks/media/docker-compose.yml`, delete the
`tautulli` service block (lines 110-121 at plan time). In `Caddyfile`, delete the
`tautulli.ginnoir.com` block (lines 196-205 at plan time).

- [ ] **Step 6: Validate both compose files and the Caddyfile**

```bash
docker compose -f stacks/streaming/docker-compose.yml config --quiet && docker compose -f stacks/media/docker-compose.yml config --quiet && echo "COMPOSE OK"
docker run --rm -v "${PWD}/Caddyfile:/etc/caddy/Caddyfile:ro" caddy:latest caddy validate --config /etc/caddy/Caddyfile --adapter caddyfile
```

Expected: `COMPOSE OK` and `Valid configuration`.

- [ ] **Step 7: Commit and push**

```bash
git add stacks/streaming/docker-compose.yml stacks/streaming/stack.env stacks/media/docker-compose.yml Caddyfile
git commit -m "chore: decommission plex

Plex is removed from valhalla. Drops jellyplex-watched (nothing left to
sync from), tautulli (Plex-only) and the tautulli Caddy site."
git push origin main
```

- [ ] **Step 8: Verify the containers are gone**

Wait 5 minutes for Portainer to poll, then:

```bash
ssh -o BatchMode=yes ginnoir@valhalla "docker ps -a --format '{{.Names}}' | grep -E 'tautulli|jellyplex' || echo 'both removed'"
```

Expected: `both removed`. If they linger, Portainer may need a manual redeploy of the affected
stack from the UI.

- [ ] **Step 9: Remove the stale Tautulli config**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "sudo rm -rf /config/tautulli && echo removed"
```

---

### Task 25: Clean up documentation and monitoring

**Files:**
- Modify: `CLAUDE.md`
- Modify: `plans/homelab-improvements/tasks/TB-027-jellyfin.md`
- Modify: `plans/homelab-improvements/tasks/TB-016-document-plex.md`
- Regenerate: `bookmarks-domains.html`, `bookmarks-ports.html`

- [ ] **Step 1: Replace the Plex section in CLAUDE.md**

Delete the entire `### Plex Media Server` block under **External services (not in compose)**. If
no other external service is documented there, remove that heading too.

Add to the stack table in the **Layout** section:

```
│   ├── streaming/         # jellyfin, jellystat + postgres, wizarr
```

- [ ] **Step 2: Add a Jellyfin note to CLAUDE.md**

Under **Known quirks / gotchas**:

```markdown
- **Jellyfin storage is deliberately split.** SQLite config lives on the root SSD at
  `/config/jellyfin`; metadata, cache, trickplay and transcodes bind to
  `/storage1/labdata/jellyfin/*`. Trickplay needs an explicit sub-bind on
  `/config/data/trickplay` because Jellyfin 10.11 moved it there and it cannot be
  relocated from the UI. Do not "simplify" these into one mount — the root disk is
  194G and has filled twice.
- **Jellyfin has no SSO, on purpose.** `jellyfin-plugin-sso` only completes OIDC inside
  a browser; Roku, Fire TV and tvOS clients cannot use it. Jellyfin uses native accounts.
  This is a deliberate exception to the Authentik standard.
- **The P100 cannot encode.** GP100 has no NVENC. Hardware *decoding* is enabled for
  trickplay generation; hardware encoding must stay off or every transcode fails.
```

- [ ] **Step 3: Close out the TB tasks**

In `plans/homelab-improvements/tasks/TB-027-jellyfin.md`, fill in the decision table:

```markdown
| **Decision** | Do it — completed |
| **Notes** | Migrated to Jellyfin in stacks/streaming. See docs/superpowers/specs/2026-08-05-jellyfin-migration-design.md and docs/superpowers/plans/2026-08-05-jellyfin-migration.md |
| **Date** | (fill in the completion date) |
```

In `plans/homelab-improvements/tasks/TB-016-document-plex.md`, mark it obsolete — Plex no longer
exists to document.

- [ ] **Step 4: Update Uptime Kuma**

In the Uptime Kuma UI:
- **Delete** the Tautulli monitor and any Plex monitor
- **Add** an HTTP monitor for `https://jellyfin.ginnoir.com/health`, expected status `200`,
  interval 60s, with the ntfy notification attached
- **Keep** the `valhalla root disk` push monitor from Task 3

- [ ] **Step 5: Regenerate bookmarks**

```bash
pwsh -File scripts/gen-bookmarks.ps1
```

- [ ] **Step 6: Verify no stale references remain**

```bash
grep -rni "tautulli\|plexmediaserver\|plex media server" . --include="*.md" --include="*.yml" --include="Caddyfile" | grep -v "docs/superpowers/"
```

Expected: **no output**. Matches inside `docs/superpowers/` are historical records of this
migration and should stay.

- [ ] **Step 7: Commit and push**

```bash
git add CLAUDE.md bookmarks-domains.html bookmarks-ports.html plans/homelab-improvements/tasks/
git commit -m "docs: retire plex, document the streaming stack

Plex is gone from valhalla. Documents the Jellyfin storage split, the
deliberate absence of SSO, and the P100's lack of NVENC. Closes TB-027
and obsoletes TB-016."
git push origin main
```

- [ ] **Step 8: Final verification**

```bash
ssh -o BatchMode=yes ginnoir@valhalla "df -h / /storage1 | grep -v Filesystem; docker ps --filter label=com.docker.compose.project=streaming --format '{{.Names}}\t{{.Status}}'"
curl -s -o /dev/null -w 'jellyfin: %{http_code}\n' https://jellyfin.ginnoir.com/health
```

Expected: root disk healthy, `/storage1` reclaimed by ~383G, four `streaming` containers `Up`
(jellyfin, jellystat, jellystat-db, wizarr), and Jellyfin returning `200`.

## Rollback summary

| Up to and including | How to roll back |
|---|---|
| Task 22 | Plex is running and untouched. Do nothing — users simply keep using it. |
| Task 23 | `sudo systemctl start plexmediaserver` |
| Task 24, within 30 days | `sudo pacman -S plex-media-server`, then extract `/storage1/labdata/plex-final-*.tar.gz` and recreate the `/var/lib/plex` symlink |
| After the tarball expires | No rollback. This is the point of no return. |

## Deferred, deliberately

- **Intel Arc GPU purchase and passthrough** — gated on Task 20's evidence, needs its own plan
- **Music and Books libraries** — out of scope per the design
- **Seerr request-history migration** — accepted loss
- **`/storage1` redundancy** — tracked separately
