A relayout renames on the raw array; the sidecars the media servers wrote live in
the NVMe upper layer of the view and stay at the old coordinates, which is how a
ghost folder (artwork and an .nfo, no video) is born. apply and rollback now
print the follow-up — scripts/media-view.sh reap — at the moment the operator
needs it, and the existing apply seam asserts the hint is in the output.
Two fixes found by one live sweep, shipped together because the second is
what makes the first finishable.
1. scripts/media-tv.py — the other half of media-plan.py's refusal to file
TV. Groups episode-shaped files by the series name before the marker
(media-titles.ep_of, imported not restated), writes a plan in the
executor's own format: <library>/<Series> (<year>)/Season <NN>/<own
name>.<ext>. Refuses a group below --min, an episode naming no season,
and an episode the destination library already holds at the same byte
count — the movie share carries a second copy of all 124 Monk episodes
the TV library has had for years; a duplicate is Frank's call, never a
tool's copy. Applied by media-apply.py with its own journal and
--root /mnt/entropy.
2. scripts/media-apply.py — gone meant "rmdir intended", so a folder whose
rmdir failed was blacklisted forever and no later sweep could finish it
(live movie sweep: 4517 targeted, 146 permanently stranded). gone now
means "actually gone": a failed intent is retried by the next sweep.
tests: 9 new tests in media_relayout.bats, each red against the previous
revision — 8 TV + 1 sweep retry behind a chmod 500 parent. ./tests/run.sh
633 green. No live move run yet.
The live sweep removed 2271 husks and left 146 standing, every one a release
folder blocked by a junk subfolder (Screens/, Sample/, a BDMV leaf) that no
file ever moved out of. Eligibility was per-folder, so the blocker was never a
target and its parent could never be removed.
Proof now carries downward: inside a folder the journal shows emptied, every
empty directory qualifies. Nothing under such a folder can hold data, and every
removal is still journalled as rmdir and undone by rollback.
The new test is red against the previous revision, green now. The live sweep
touched no file: 8193 before, 8193 after.
An apply leaves every release folder it emptied standing where it was: the
live library run left 1675 husks at the root. sweep takes the same journal
and deletes only folders it can prove this run emptied - a journalled move
out of the folder or something under it, nothing but empty directories left,
no journalled destination beneath it, not a folder the run created. A folder
nobody moved cannot be selected at all, so a hand-made placeholder survives,
and a symlink anywhere inside disqualifies the subtree. Every rmdir is
journalled, so rollback recreates what a sweep removed.
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.
