The Movies relayout planned from Plex; the TV library has no Plex rows and
58k files whose names lie about which episode they hold. Jellyfin has already
matched and numbered 47,676 of them, so the planner treats that numbering as
the authority and the file name as the fallback: an episode number the name
states, or a provider row, or nothing - and "nothing" parks the file under
_unsorted with a reason instead of inventing a number.
- media-census.py jellyfin: one TSV row per matched episode, its container
path mapped back to the host, series name/year/TMDb id from the Series row
(the episode row carries none of them). Both TSV writers now end lines with
\n so a shell consumer sees the last field clean.
- media-shows.py: the plan. Series folders take the provider's own spelling;
one file claiming two episodes keeps both numbers; two files claiming one
episode - the bigger keeps the standard name, the other parks; bonus
material files under the series' extras folder, never as an episode; a long
file inside the TV library leaves for Movies only when TMDb answers with a
matching title, otherwise it parks. Re-running the plan on a library it
already filed moves nothing.
- tests/media_shows.bats: 15 behaviors, including the executor preflight and
the re-plan stability law.
The movie library on the entropy volume is release-folded: the video inside
`Some.Movie.2019.1080p…-FOO/` is named after the release, and Jellyfin matches
a movie by folder and file name, so the noise cost posters, extras and versions.
Three scripts own the fix, and nothing else in the repo moves a media file.
* media-census.py the read-only inputs: a stat pass, an ffprobe header pass
(nice'd, so it is safe beside a live endpoint), and the
Plex metadata cache read that outranks any filename guess
* media-plan.py the Jellyfin-format planner: one folder per movie, the
video named exactly like the folder, extras in the
canonical subfolders, copies of one film as versions. It
opens no media file, so a whole-library plan costs seconds,
and it ends in gates — bad-names, occupied, double-claim,
left-unmoved, unplanned — that must all read zero before a
human points the executor at 24 TB
* media-apply.py the executor: rename(2) only, the intent fsynced to a
write-ahead journal BEFORE the move it authorises, so an
interrupted run is finishable and every run is undoable.
Refusals are all-or-nothing and it never overwrites a file
Laws the fixture pins (tests/media_relayout.bats, 16 tests, each proven red
against a reverted copy of the rule it guards):
* a Plex year of 0 means "indexed, never matched" — trusting it produced
folders "Title (0)": items with no year, no poster, no identity
* a Plex title carrying "/" is sanitised, or "V/H/S/2" became a five-level
tree neither matcher reads as a movie
* a folder inside a movie's folder is bonus territory even when its name is
misspelled ("Exrtas"), unless the file's own name carries another year
* matching words split on everything but a letter or digit — the earlier
tokenizer left "(1960)/extras" glued, so a film could not be found by the
folder holding it and one box set's featurettes drifted into a neighbour
* a name with no words in it is bonus material, never a movie folder named 1

links it from the runbook index and the summary table.
