Two relayouts writing one journal cannot be rolled back apart: the mover
(Movies -> TVShows) and the library re-filer both pointed at
media-relayout-tv.jsonl. The re-filer now writes media-relayout-shows.jsonl,
and its plan/exceptions move off /tmp, which a reboot eats and which is not a
record.
The page said the music plan "was applied" while 62k of its 131k journal rows
were still being written; a runbook line that gets believed is worse than none.
Also lands the single-writer law the audiobook handoff exists to honour, and the
durable plan path (/tmp is not a record).
Plex's artist row for 272 chapters is a chapter number the ripper put in the
artist tag (0.4, 31, 05), which would have filed them under a shelf called 0.4.
A narrator is a person, so it must contain a letter; the same test is deliberately
not applied to a book title, which may honestly be 1984.
The first real plan filed 1,106 chapters from 14 unrelated top-level folders
onto one shelf, because all 1,106 carry the album tag [Unknown Album] and the
same artist tag. Plex's album title is the authority for the shelf only when it
names a book; a placeholder names nothing, and unrelated books share it. Those
chapters now park with the path they have today, timestamp-glued variants
included; Various Artists stays a legitimate multi-cast narrator.
The linter caps a page at 500 lines and a description at 120 chars: the section
lost four lines of prose (no law went with them) and the description lost its
restatement of the format names. gen-vault-index.py regenerated the locator row.
One page owns the relayout facts: the new section carries the Plex-only reader,
the shape, the four commands, and the two laws a future operator would otherwise
re-litigate (never renumber a chapter; the shelf is the narrator). The music
section said its plan was NOT applied — it was applied on 2026-10-31, and a stale
line in a runbook gets believed, so it now names the journal and the rollback.
The audiobook tree is the one library Jellyfin does not read at all and Plex
reads completely: 58,975 chapters matched into Artist/Album/Track, where the
album is the BOOK and the book's single artist row is the NARRATOR. That is the
authority the new planner files by, never the collection folder a pack made.
Audiobooks/<Narrator>/<Book> (<year>)/<the file's own name>
Two laws are the opposite of the music tool's, both forced by the rows: files
are never renumbered (72% of the books carry chapters with no usable index, and
playback order comes from the embedded track tag either way, so an invented
number can only lie), and the shelf is the narrator, not the author (every book
has exactly one artist row; the author survives in 10% of album titles and in no
column Plex stores, so one rule beats a shelf half authors and half narrators).
media-census.py gains the audiobooks export: the chapters Plex matched under a
root, host paths straight through, nothing outside the root and nothing Plex
deleted. 22 tests in tests/media_audiobooks.bats pin the export's join and the
plan's output.
A scan answers 204 whether or not it found anything, so proof is the journal
replayed against Jellyfin's BaseItems.Path and Plex's media_parts.file: every
move has a row at its dst, no row names its src. Records the four wrong doors:
no sqlite3 binary on the hosts or in either container, Jellyfin's single
BaseItems table (no MediaItems), its container-side /data path prefix, and
Plex's HTTPD closing on ?path= / on /search matching titles not paths.
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
Docs: the runbook page owns the procedure, the gates and the rollback; AGENTS.md
links it from the runbook index and the summary table.
