docs(media): the TV library's own relayout, with the evidence chain it believes

One page owns relayout: the census commands, the order the planner believes
things in, the two refusals a dry run on the real library proved necessary, the
apply and rollback path, and the standing wart that a provider name can itself
be scene junk ("Black Clover 001", 92 episodes) — renaming that is Jellyfin's
job, not the mover's.

+r"""Plan a Jellyfin-format relayout of a TV library. DRY RUN ONLY: nothing moves.
+
+ media-shows.py [--root DIR] [--enum TSV] [--titles TSV] [--probed TSV]
+                [--tmdb-cache JSON] [--tmdb] [--movies DIR] [--park DIR]
+                [--out TSV] [--exceptions TXT]
+
+Inputs are the TSVs scripts/media-census.py exports: `enumerate` lists what
+exists, `jellyfin` says which episode each file IS, and `probe` is optional
+duration evidence for the movie rule. The TMDb cache is a plain JSON file so a
+plan stays reproducible: answers are read from it, and a miss is looked up only
+with --tmdb and TMDB_API_KEY in the environment (the key never enters argv, and
+never the cache).
+
+Target contract (jellyfin.org/docs/general/server/media/shows):
+
+    <root>/<Series> (<year>)/Season <NN>/<Series> SxxEyy.ext
+    one file holding two episodes   SxxE01-E02      specials       Season 00
+    a documented part of an episode SxxE03 Part 1   sidecars       <base>.<lang>.srt
+    bonus material                  <series>/trailers|featurettes|… — never a season
+
+PLAN is the TSV scripts/media-apply.py replays: `action src dst kind`, every
+mkdir row before any move, and `keep` for a file already where the contract puts
+it. EXCEPTIONS is the review list: everything parked, and why.
+
+The authority chain, strongest first, for one video file:
+
+  1. a provider row — Jellyfin matched this exact path and numbered it.
+  2. the file's own SxxEyy / 1x04 marker, the series taken from a sibling's
+     provider row, else from the nearest ancestor folder that has one, else from
+     the release folder's own words.
+  3. nothing. An unnumbered file is PARKED under --park with its relative path
+     kept: an invented `Season 01` steals an episode number from the file that
+     really is S01E01, and a wrong number is worse than no number.
+
+Guards, and why each is here:
+
+  * One series, one folder, one year: the year ANY provider row of a series
+    states is shared by all of them, so a box set split across five release
+    folders lands inside ONE series folder instead of five.
+  * Two files claiming one episode: the bigger keeps the standard name, the other
+    parks with the reason. Nothing is overwritten and nothing is deleted — which
+    encode survives is Frank's call, and a parked file is one rename from home.
+  * A file with no episode evidence that runs long and that the MOVIE provider
+    names leaves the TV library for --movies under the movie naming contract.
+    Long and unnamed parks; short and unnumbered is bonus material.
+  * Series art and the show nfo follow the SERIES, a season image follows its
+    SEASON, a subtitle or episode nfo follows the episode's new base — an episode
+    moved without its subtitles is a half-move.
+  * Hidden files, macOS forks, qBittorrent resume parts and the park pile itself
+    are never moved. Skipping the park is what makes re-planning stable.
+
+The plan crosses three trees (the library, its park, the movie library), so the
+executor runs with --root at the share that holds them, on its own journal —
+one journal is one undo:
+
+    python3 scripts/media-shows.py --root /mnt/entropy/TVShows \
+        --enum /tmp/tv-enum.tsv --titles /tmp/jellyfin-tv.tsv \
+        --out /mnt/entropy/media-tv-plan.tsv
+    python3 scripts/media-apply.py apply --plan /mnt/entropy/media-tv-plan.tsv \

+"""media-tv.py — move TV episodes out of the movie library into a TV library.
+
+`scripts/media-plan.py` refuses to file TV: it parks episode files in a
+`_TV needs a TV library - <series>` pile for a human. This is the other half of
+that refusal. It walks the movie library, groups the files whose own name
+carries an episode marker by SERIES, and writes a plan that places each series
+in the shape both Jellyfin and Plex read without help:
+
+    <library>/<Series> (<year>)/Season <NN>/<the file's own name>.<ext>
+
+It writes a plan and nothing else. Every rename belongs to
+`scripts/media-apply.py` — the write-ahead journal, the refusal to overwrite,
+the all-or-nothing preflight, the rollback. Apply it with `--root` set to the
+share that holds BOTH libraries (`/mnt/entropy`, not `/mnt/entropy/Movies`) so
+the executor's own path guard still has teeth, and give it its own journal —
+one journal is one undo, and a TV move must not be welded to a movie relayout:
+
+    python3 scripts/media-tv.py --root /mnt/entropy/Movies \
+        --library /mnt/entropy/TVShows --out /mnt/entropy/media-tv-plan.tsv
+    python3 scripts/media-apply.py apply --plan /mnt/entropy/media-tv-plan.tsv \
+        --root /mnt/entropy --journal /mnt/entropy/media-relayout-tv.jsonl
+    python3 scripts/media-apply.py verify --plan /mnt/entropy/media-tv-plan.tsv \
+        --root /mnt/entropy --journal /mnt/entropy/media-relayout-tv.jsonl
+    python3 scripts/media-apply.py sweep --root /mnt/entropy \
+        --journal /mnt/entropy/media-relayout-tv.jsonl --apply
+
+Guards, and why each one is here:
+
+* The same five-file threshold as the planner. An episode-shaped name on one
+  file is not a series — `The Godfather Part 2` is a film — so a smaller group
+  is reported and left exactly where it is.
+* An episode whose name carries no season number is reported and left, never
+  filed into an invented `Season 01`.
+* A sidecar that shares an episode's own name (`.srt`, `.nfo`, …) follows the
+  episode; an episode without its subtitles is a half-move.
+* A group that would claim one destination twice is not resolved here. The
+  executor refuses the whole plan before its first rename, which is the right
+  outcome: nobody but Frank decides which copy of an episode is the keeper.
+* An episode the destination library already holds at the same byte count is
+  left where it is. The TV library has held a complete Monk box set for years
+  while the movie library carried a second copy of all 124 episodes; a mover
+  that did not look where it was filing would have put both inside one library.
+* A symlink is never followed and never moved.

+# The SSD-backed metadata view that lets Jellyfin and Plex share one metadata set.
+#
+# Both servers read a Kodi-format sidecar (movie.nfo / tvshow.nfo / episode.nfo)
+# ONLY when it sits next to the media file. The media lives on the RAID6 array at
+# /mnt/entropy — five spinning disks, deliberately mounted read-only for every
+# container, and slow to seek for a thousand tiny XML reads. So neither media
+# server binds the array any more: they bind an OverlayFS merge of it with a
+# writable layer on the NVMe.
+#
+#   lowerdir  /mnt/entropy                RAID6 (ROTA=1) — source of truth, never written
+#   upperdir  /var/lib/media-meta/upper   NVMe — every sidecar and image byte
+#   workdir   /var/lib/media-meta/work    NVMe — kernel bookkeeping
+#   Where     /var/lib/media-meta/view    the merged tree jellyfin and plex bind
+#
+# Everything the view needs — layers, bookkeeping, trash, the merged door — lives
+# under the one directory /var/lib/media-meta, so nothing new appears under /mnt.
+#
+# Consequences worth knowing:
+#   * A sidecar write is a few KB onto the SSD; the media bytes never move and the
+#     array is still never written by anything automated.
+#   * Deleting through the view writes a whiteout into the upper layer instead of
+#     deleting from the array. Nothing should delete through the view: deletions
+#     go to .AGENTTRASH on the RAW path, and `reap` clears the resulting ghosts.
+#   * inotify events on the lower layer do not cross the merge, so a file that
+#     arrives on the raw array is invisible to a file-system watcher in the view:
+#     trigger a library refresh (see the Media Relayout page).

+
+**Failure signature:** `System.IO.IOException: Read-only file system :

+instead of the view — the view is unmounted or the quadlet drifted. That used to

+- **TVDB is installed and keyed but is not a metadata agent**: TMDb still
+  identifies everything. Enabling TVDB as a provider would re-fetch show

+- **The deployer places the keys before it restarts jellyfin**
+  (`ensure_provider_keys` in `scripts/deploy-remote.sh`) and warns instead of

+# Media Metadata View
+
+`/var/lib/media-meta/view` is an OverlayFS merge of the media library: the RAID6
+array below, a directory on the NVMe above. It exists so [[Jellyfin]] can write
+Kodi-format sidecars (`movie.nfo`, `tvshow.nfo`, `episode.nfo`, artwork) that
+[[Plex]] can read. Sidecar metadata is only useful sitting next to the media
+file, and the array is read-only and slow — so the media bytes stay there and the
+*writes* land on SSD. One tree to both servers, one copy of the media.
+
+The mount point is not a volume and holds nothing while unmounted. It sits inside
+`/var/lib/media-meta` so that layers, kernel bookkeeping, the reap trash and the
+merged door are one directory — and so the mount table grows no new `/mnt` entry
+next to the array.
+
+## Shape
+
+| Item | Value |
+|---|---|
+| Lower layer | `/mnt/entropy` — the RAID6 array, source of truth, never written |
+| Upper layer | `/var/lib/media-meta/upper` — NVMe; every write lands here |
+| Work dir | `/var/lib/media-meta/work` — overlayfs internals, same filesystem |
+| Mount point | `/var/lib/media-meta/view` — the merged tree both servers bind |
+| Unit (repo) | `dankserver/host/systemd/media-meta-view.mount` — the source of truth |
+| Unit (host) | `var-lib-media\x2dmeta-view.mount` — systemd names a mount unit after its escaped path (`-` becomes `\x2d`); `media-view.sh install` writes the repo file under that name |
+| Installer | `scripts/media-view.sh` — `plan` / `install` / `verify` / `status` / `reap` |
+| Written by | Jellyfin only (Plex binds read-only); nothing else in the fleet touches it |
+
+Both consumers guard the view with
+`UnitConfigItem=ConditionPathIsMountPoint=/var/lib/media-meta/view`, and
+`scripts/deploy.sh dankserver --service jellyfin|plex` calls `media-view.sh
+install` + `verify` before it restarts either container.
+
+| Consumer | Bind | Mode | Why that path |
+|---|---|---|---|
+| [[Jellyfin]] | `/var/lib/media-meta/view:/data` | rw | It is the metadata writer; its sidecars become SSD bytes |
+| [[Plex]] | `/var/lib/media-meta/view:/mnt/entropy` | ro | Every path in the PMS database was recorded as `/mnt/entropy/...`; only the HOST side of the bind moved, so its database still resolves |
+
+Putting the sidecars inside Plex's reach is not the same as making Plex use them:
+a library parses `.nfo` only with its *Local media information* agent enabled, and
+this change touches no library setting.
+
+## Commands
+
+```bash
+scripts/media-view.sh plan              # print the resolved shape, touch nothing
+sudo scripts/media-view.sh install      # create dirs, install the unit, mount, enable
+scripts/media-view.sh verify            # is the view really the overlay? (deploy gate)
+scripts/media-view.sh status            # mount options + upper-layer size/file count
+scripts/media-view.sh reap              # list ghost metadata (media moved, sidecars left)
+sudo scripts/media-view.sh reap --apply # move ghosts to the SSD trash, never delete
+```
+
+`--upper-base DIR` and `--lower DIR` relocate the layers for `plan` and `reap`;
+the defaults are the host values above.
+
+## Laws
+
+- **The upper layer must sit on non-rotational storage.** `install` and `verify`
+  refuse via `lsblk -dno ROTA` if the upper base lives on the array: an overlay
+  whose upper is the spinners is the original problem with extra steps, and it
+  silently turns every metadata write back into a seek.
+- **Never mount the view over an unmounted lower.** `RequiresMountsFor=/mnt/entropy`
+  plus the container `ConditionPathIsMountPoint` guards: an empty `lowerdir`
+  presents an *empty library* as truth, and a media scan would then clear the
+  database of everything. systemd does not create a mount point, so `install`
+  creates `view` itself; without it the mount simply fails.
+- **Never delete through the view.** A delete writes an overlayfs whiteout
+  (`.wh.<name>`) in the upper layer, which hides the array's copy without
+  removing it — the file reappears the moment the view is unmounted, and the
+  upper layer now carries a landmine. Deletions belong on the raw path
+  (`/mnt/entropy`), which the relayout tool already treats as the only writer.
+  `reap` refuses to remove whiteouts and only warns about them.
+- **A relayout must be followed by `reap`.** Renames happen on the raw path, so
+  sidecars the view already wrote stay at the old coordinates: a ghost folder
+  the servers browse and find nothing in. `reap` lists upper-layer directories
+  with no counterpart below and moves them (with their subtree) into a dated
+  `.AGENTTRASH/` under the SSD base. It is recursive and file-safe: a sidecar
+  that exists only above is normal, so only *directories* are candidates.
+- **File-watcher events do not cross the overlay.** Plex's NFO agent and
+  Jellyfin's real-time monitor see inotify events for writes that land *in the
+  upper layer*, not for changes on the array underneath. After any relayout or
+  externally-written metadata, trigger a library refresh — see
+  [[Media Relayout]] for the refresh procedure.
+
+## Failure signatures
+
+| Symptom | Meaning |
+|---|---|
+| `jellyfin.service` / `plex.service` show `ConditionPathIsMountPoint=... was not met` and stay inactive | The view is not mounted. Do not start them anyway: `scripts/media-view.sh install`, then `verify`. |
+| Jellyfin log: `Read-only file system : '/data/Movies/…/movie.nfo'` | The container is binding the raw array, not the view — the quadlet drifted back or the view is gone. `media-view.sh status`. |
+| A folder appears in a media server with artwork/`.nfo` but no video | Ghost metadata from a relayout. `media-view.sh reap`. |
+| `verify` prints `refused: …/view is not a mountpoint` | A plain directory is sitting where the overlay belongs. That is the fail-closed guard working; `install` on the box. |
+| `systemctl status` finds no such unit | Look under the escaped name, `var-lib-media\x2dmeta-view.mount`, not the repo file name. |
+
+## Rollback
+
+Revert the commit that pointed the two quadlets at the view and re-deploy both
+services — they bind `/mnt/entropy` read-only again, which is the pre-view shape.
+The NVMe upper layer can stay: nothing reads it once the binds are back, and it
+holds no state either server needs. Unmounting alone
+(`systemctl stop 'var-lib-media\x2dmeta-view.mount'`) is safe while no container
+binds it, and the array is never modified by any of this.

+
+## TV in the movie library
+
+A box set that arrives in the movie share stays there until someone moves it:
+`media-plan.py` refuses to file TV and parks each series in
+`_TV needs a TV library - <series>`. `scripts/media-tv.py` is the mover. It
+walks the movie library itself (no census needed), groups episode-shaped names
+by series, and writes a plan in the executor's own format:
+
+```bash
+scripts/media-tv.py --root /mnt/entropy/Movies --library /mnt/entropy/TVShows \
+    --out /mnt/entropy/media-tv-plan.tsv
+scripts/media-apply.py apply --plan /mnt/entropy/media-tv-plan.tsv --root /mnt/entropy
+scripts/media-apply.py apply --plan /mnt/entropy/media-tv-plan.tsv --root /mnt/entropy \
+    --journal /mnt/entropy/media-relayout-tv.jsonl --apply
+scripts/media-apply.py sweep --journal /mnt/entropy/media-relayout-tv.jsonl \
+    --root /mnt/entropy --apply
+```
+
+The shape it writes is the one both matchers read — `Monk (2002)/Season 05/
+Monk - S05E03 - Mr. Monk and the Big Game.mkv` — keeping the file's own name,
+because the publisher's spelling beats a re-derivation, with the year taken
+from the box-set folder. What it refuses it prints and leaves alone:
+
+- fewer than `--min` (5) files under one series name: one file named `Part 2`
+  is a film, not a series;
+- an episode whose name states no season number — no invented `Season 01`;
+- a destination two files both claim: the executor refuses the whole plan
+  before its first rename, and only Frank decides which copy is the keeper.
+- an episode the destination library already holds at the same byte count. The
+  movie share carried a second copy of the whole Monk box set — 124 episodes
+  both sides, the same episode list, every byte count identical, 31.5 GiB each
+  way, and head+tail blake2b identical on a 6-episode sample. The mover leaves
+  such a series in place and says so; a duplicate is deleted or kept by Frank,
+  never copied into one library by a tool.
+
+A sidecar that shares an episode's own name (`.srt`, `.nfo`) moves with it.
+
+Below the threshold the mover prints and leaves, so a lone downloaded episode of
+a real show stays in the movie library on purpose — six did on 2026-10-30.
+Filing one by hand is the same executor on a hand-written plan and the same
+journal; the trap is the series year. Read it from the file's own name or the
+folder it owns, never from the title whose bonus folder it happens to be parked
+in — `The Cleveland Show S03E07` inside `Die Hard (1988)/extras/` is not a 1988
+show. A name whose marker is `Part 2` is a film and stays put.
+
+## The TV library's own relayout
+
+`/mnt/entropy/TVShows` is scene packs rather than a library, and Jellyfin has

+library into the same shape, and it never guesses: every series name and every
+episode number it writes traces to an authority, and what has none is parked for
+a human to read.
+
+```bash
+# 1. The authority: Jellyfin's own matched rows (the DB opens read-only).
+python3 scripts/media-census.py jellyfin --root /mnt/entropy/TVShows \
+    --out /tmp/tv_titles.tsv
+# 2. What is on disk (stat only), and the runtimes the film arm needs.

+python3 scripts/media-census.py probe --root /mnt/entropy/TVShows \
+    --enum /tmp/tv_enum.tsv --jobs 6 --out /tmp/tv_probed.tsv
+#    The probe is the slow step: ffprobe reads both ends of every file.
+# 3. The plan. --tmdb needs TMDB_API_KEY; without it a series no provider dated
+#    is simply named without a year, which Jellyfin accepts.
+python3 scripts/media-shows.py --root /mnt/entropy/TVShows --enum /tmp/tv_enum.tsv \
+    --titles /tmp/tv_titles.tsv --probed /tmp/tv_probed.tsv \
+    --out /tmp/tv_plan.tsv --exceptions /tmp/tv_exceptions.txt

+    --journal /mnt/entropy/media-relayout-tv.jsonl --apply
+```
+
+Evidence, strongest first — the order the planner believes things:
+
+- the **episode marker the file's own name states** (`S01E02-E03`, `1x04`);
+- the **`Season NN` folder it sits in and the number its name leads with inside
+  it**: `Season 19/01 Charles Barkley, Nirvana.avi` is S19E01;
+- the **provider row**: identity (the series name and its year), and the
+  numbering of a file whose own name says nothing;
+- a **bonus folder** anywhere above the file, or Jellyfin's `ExtraType` → the
+  series' canonical extra folder;
+- a runtime over `SHORT_MAX` makes it film-shaped, and it leaves for `--movies`
+  only when a movie provider names it — otherwise it parks.
+
+Two refusals carry the design, and a dry run on the real library found both:
+
+- **Folders resolve a series; they never invent one.** A folder's words may
+  resolve a file to a series a provider has already named — `(CBB) Tengen Toppa
+  Gurren Lagann - The Complete Series (BD 1080p)` names the registered *Tengen
+  Toppa Gurren Lagann* — but a bonus subfolder is not a show. An early run made
+  `…/03. Extra/01. NCOP/NCOP 01.mkv` into a root series called `01 NCOP`.
+- **A scraped row does not outrank the filesystem.** Jellyfin numbers
+  multi-season packs badly: every file under `SNL 16-20/Season 16..19` carries
+  season 16 episode 20, and one Gundam row says season 2004. The folder, then
+  the file's own leading number, win; a row that still insists on season 1989
+  parks its file instead of creating `Season 1989`.
+
+The provider's name is copied verbatim, warts included: Jellyfin carries a Series
+named `Black Clover 001` (92 episodes, no year) because it matched a pack off a
+filename. Renaming a show is Jellyfin's work — a folder rename never touches its
+provider ids — so the mover keeps the name it is handed and strips only the pack
+index a release leads with (`4a. Seed DESTINY` → `Seed DESTINY`).
+
 ## Laws
 
-- **The journal lives beside the library, never in `/tmp`.** The live run's
-  `/mnt/entropy/media-relayout.jsonl` is the only rollback instrument; a journal
-  a reboot clears is not an instrument.
-- **An apply breaks [[Plex]] playback for every moved item until its section is
-  rescanned.** The database keeps the release-folder path, so streams fail
-  `Couldn't find the file to stream` while the scanner works through the section.
-  Trigger the scans in the same window as the apply, and never read a 404 in that
-  window as a lost file — the file is where the journal says it is.
+- **A moved file is a 404 in [[Plex]] until its section is rescanned.** The
+  database keeps the release-folder path, so playback fails `Couldn't find the
+  file to stream` while the scanner works through the section. Never read such a
+  404 as a lost file: the file is where the journal says it is.
 - **Plex's matched title outranks the filename**, and a Plex year of `0` means
   *indexed but never matched* — trusting it named folders `Title (0)`, which is
   a Jellyfin item with no year, no poster and no identity. A year that is not a

   folder holding it, and extras drifted into a neighbour. A bare number counts
   only when it could be a release year, so `1080` and `2160` never pose as
   agreement between two names.
+- **Compare two media libraries with the series engine, never a path
+  substring.** Filtering paths for `monk` also returns *Monkey Dust*, and
+  letting whichever file a walk happens to reach first stand for an episode
+  paired two libraries into a fake duplicate — the same sloppiness pointed the
+  other way deletes a file that is unique. The comparison is `media-titles.ep_of`
+  on both sides: series, season, episode, bytes, and a hash before anything is
+  trashed.
+- **A deletion is staged on the item's own filesystem.** The trash rule names
+  `~/.AGENTTRASH`, but `/home` and `/mnt/entropy` are different devices: a 31 GiB
+  stage there is a copy rather than a rename, it has to fit in the 187 GiB of
+  free space, and `rename(2)` refuses it anyway. Trash goes beside the item —
+  `/mnt/entropy/.AGENTTRASH/<date>-<topic>/` — so it costs one inode change and
+  rolls back exactly like the move that made it.
+- **A Jellyfin 401 is the header, not the key.** 12.4 authenticates only
+  `Authorization: MediaBrowser Token="…"` and refuses a bare `X-Emby-Token` for
+  every key, valid or not. This page carried "no credential on this box can
+  trigger a scan, the two Seerr keys answer 401" for weeks because of that
+  header — the keys were innocent. Before believing a 401, prove the key against
+  the server's own table: `select count(*) from ApiKeys where AccessToken = ?`
+  on `jellyfin.db` opened `mode=ro&immutable=1`.
+- **A scan that must see a new folder has to be recursive.** `POST
+  /Library/Refresh` is the incremental pass, and inotify does not cross a
+  rootless podman bind, so folders created on the host stay invisible to it. The
+  move is `POST /Items/{id}/Refresh?Recursive=true` (204) per library, the id
+  from `GET /Library/VirtualFolders` — its field is `ItemId`, not `Id` — and
+  that same record's `RefreshStatus` is the progress read.
 - **A file whose name carries no words is bonus material, not a folder.**
   `.Extra 1 ( 1H 27min multisub ).mkv` parses to `1`; a movie folder named `1`
   is not a movie. It becomes a review line telling a human to name the file.

   inside disqualifies the subtree, because the thing behind a link is not this
   tool's to delete. Every removal is journalled as `rmdir` and `rollback`
   recreates the folder, so the sweep is undone by the same command as the moves.
+  Proof carries downward: inside a folder the journal proves emptied, every
+  empty directory goes with it. A release's `Screens/` or `Sample/` is never a
+  move source itself, so 146 of them held their emptied parents on disk after
+  the first sweep.
+  A failed `rmdir` is not a removal: only a folder that is really gone leaves
+  scope, so the next sweep finishes what a permission problem stopped.
+- **An episode-shaped name marks a SERIES, not a film — and the series is the
+  name BEFORE the marker.** `Monk - S05E03 - Mr. Monk and the Big Game` is series
+  `Monk`. Keyed on the whole title instead, every episode became a group of one
+  and never reached the five-episode size that calls something a series, so a
+  box set was filed as 124 movies in 124 folders. The threshold still earns its
+  keep: a lone film named `Part 2` stays a film. Episodes of a series are parked
+  in `_TV needs a TV library - <series>` for a human to move to a TV source —
+  the movie tool never files TV.
+- **One journal is one undo.** The TV move runs on its own journal, and with
+  `--root` set to the share that holds BOTH libraries: the executor refuses any
+  path outside `--root`, and a journal shared with the movie relayout would
+  undo both runs when only one of them is wanted.
+
+- **Sidecar metadata does not follow a rename, because it lives on another
+  filesystem.** The media servers write `.nfo` and artwork through the
+  [[Media Metadata View]] (NVMe upper layer); this tool moves bytes on the raw
+  array path. After any sweep or TV move, run `scripts/media-view.sh reap`, then
+  the same command with `--apply`: the sidecars left at the old coordinates become
+  ghost folders — artwork and an `.nfo` with no video — that both servers browse
+  and report as content.
+- **Nothing deletes through the metadata view.** A delete there writes an overlayfs
+  whiteout in the upper layer, which hides the array's copy without removing it;
+  the file returns when the view is unmounted. Deletions in this pipeline happen
+  on the raw path only, which is what the journal can undo.

+# The contracts, in the order the seam tests them:
+#   1. the plan puts the writable layer on the SSD and the media layer below it;
+#   2. bad input is refused by name instead of mounting something surprising;
+#   3. verify refuses a view that is not mounted (so nothing trusts a directory);
+#   4. both media units bind the VIEW and refuse to start without it;

+#      raw volume, so the blast radius is two containers;
+#   6. the deployer brings the view up BEFORE it restarts either server;

+# Seam: the TV-library relayout — scripts/media-census.py jellyfin (the metadata
+# authority export) and scripts/media-shows.py (the plan).
+#
+# The TV library is 52k files written in five different release layouts, and the
+# one thing that makes a rename of that size survivable is that the plan is
+# derived from what a metadata provider already matched, not from a guess at the
+# file name. So every test here states which authority a file had — name only,
+# provider only, both, neither — and asserts where the PLAN files it, never how
+# the planner decided. A fixture Jellyfin database stands in for the live one and
+# the TMDb cache is an input file, so no test touches the network.
+#
+# The two outcomes that cost a re-run of a 50k-file plan are a file filed as an
+# episode that is not one (it steals an episode number from its real owner) and a
+# move that lands on an existing file. Everything below is written to catch
+# exactly those, plus the gate that matters most: the plan must be replayable by
+# scripts/media-apply.py, whose preflight is the fleet's only overwrite guard.
