+timestamp: 2026-11-01T01:00:00Z

+
+# Media Duplicate Prune
+
+The movie library holds the same film twice in two different ways — the same file
+downloaded again, or the same film grabbed a second time at another quality — and
+[[Entropy Volume]] is permanently full, so both are worth finding. They need
+different rules, and neither is decided by name similarity alone.
+
+`/mnt/entropy/media-park` was a third kind: a parking lot that held whole shows
+and films nothing served. It is gone; its contents went to `NeedsProcessing`.
+
+## What counts
+
+| Class | Test | Action |
+|---|---|---|
+| Byte-identical | equal size, equal content hash | keep one copy, hold the rest |
+| Same work, worse encode | same title, same year, every runtime within 5 % | keep the largest — Frank's rule |
+| Different cut | same title and year, runtimes more than 5 % apart | **never touched**: an extended and a theatrical version are different products |
+| Same words, different film | title matches, year or duration does not | never grouped — this is the false-merge class that would destroy a unique file |
+
+## The screen
+
+The array cannot afford a full-content read, so identity is established in steps
+and each step only narrows what the next one touches:
+
+1. `scripts/media-census.py enumerate` — size is free, and identical files share it.
+2. Head+tail `blake2b`, 4 MiB at each end, on the size collisions only.
+3. **Before anything moves**, confirm with a sparse-window hash: 32 MiB at eight
+   evenly spaced offsets. Re-hashing a remux-heavy set in full read 150 GiB for
+   the better part of an hour; the sparse window cost 50 s, a file that merely
+   shares its head and tail cannot survive it, and the destination is a
+   recoverable hold rather than a deletion.
+4. Durations come from `scripts/media-census.py probe` — the relayout's own
+   census. Do not hand-roll a second probe: it re-seeks the array for an answer
+   the repo tool already produces, and a probe is the one census step that costs
+   hours instead of seconds.
+
+## Which copy survives
+
+In order: not one inside an `extras`, `featurettes`, `samples` or `trailers`
+folder (an extra is not a copy of the film, and extra names collide across films);
+then the shallowest path; then the file whose name equals its `Title (year)`
+folder; then the largest. For the same-work class the largest is the answer, and
+the canonical-name rule only breaks a tie — without it a `Film - 1080p.mkv` can
+outlive `Film.mkv` for no reason but a space sorting before a dot.
+
+## Guards
+
+Each of these is a file that would have been destroyed without it:
+
+- **`.!qB` is qBittorrent state, not a duplicate.** It can be byte-identical to
+  the finished file while qB still counts the download incomplete; moving it
+  breaks the re-check and re-downloads the film. Report it, leave it. Both
+  leftovers in `Movies` are 13 months stale, so they are Frank's purge decision,
+  not a prune decision.
+- **Require a year, and keep digits in the title.** Stripping digits merged
+  *Akira — Teaser 1* with *Teaser 2*; without a year, two different extras that
+  happened to share a name merged.
+- Both members must be feature length, and a name carrying `disc`, `cd` or `part`
+  is excluded: half a multi-disc release is not a copy of the other half.
+- Media containers only. Grouping every extension buries the report in subtitle
+  and cover pairs — and a duration guard that appears to fire on 720 groups is
+  counting subtitles, not protecting films.
+
+## The hold
+
+Nothing is deleted. Every doomed copy moves into a dated hold with the same
+executor the relayout uses, so any file comes back:
+
+```bash
+scripts/media-apply.py apply   --plan /mnt/entropy/dup-prune-similar-plan.tsv \
+    --root /mnt/entropy --journal /mnt/entropy/dup-prune-similar.jsonl          # dry
+scripts/media-apply.py apply   --plan … --root /mnt/entropy --journal … --apply
+scripts/media-apply.py verify  --plan … --journal /mnt/entropy/dup-prune-similar.jsonl
+scripts/media-apply.py sweep   --journal /mnt/entropy/dup-prune-similar.jsonl --root /mnt/entropy --apply
+scripts/media-apply.py rollback --journal /mnt/entropy/dup-prune-similar.jsonl --root /mnt/entropy --apply
+```
+
+The plan rows are the tool's own format (`action src dst kind`, `mkdir` rows for
+every hold parent), and the planner re-checks the two things that go stale between
+analysis and apply: a file that has moved since the census, and a group whose
+keeper is missing — either one drops the whole group rather than half-applying it.
+
+- **A hold on the same volume frees nothing.** The purge is a separate, approved
+  act and the only thing that moves the free-space number; `df` does not budge
+  when 1 TiB moves sideways.
+- `sweep` removes the release folders the pass emptied. Empty folders dated a year
+  ago are torrent detritus (`Subtitle,info`, `Screens`, `Sample`) from a previous
+  era, not this pass — read the mtimes before blaming the prune.
+- The 2026-11-01 pass held 226 files (~1.1 TiB) in
+  `/mnt/entropy/.AGENTTRASH/20261101-duplicate-prune`, journals
+  `dup-prune-exact.jsonl` and `dup-prune-similar.jsonl`. Purge pending Frank's word.
+
+## After the pass
+
+Both servers still hold rows for files that are now in the hold, and neither
+notices: the media bind is the [[Media Metadata View]], and array changes do not
+cross it as inotify events. Scan in the order the rescan law sets — Jellyfin to
+`Idle`, then Plex's Movies section alone, one accepted refresh each; the requests
+are owned by [[Jellyfin]] and [[Plex]].
+
+As of 2026-11-01 the Plex leg is deliberately deferred: Plex is stopped and
+**masked** (`systemctl --user stop plex && systemctl --user mask plex`) so its
+metadata fetches cannot stack on Jellyfin's live scan, and a masked unit stays
+stopped through a reboot — `unmask` before starting it. Its Movies section (key 1)
+holds ~187 rows naming held paths until that one refresh is accepted.
+
+The same evening's detritus pass is a second, separate hold: 423 files (12 MiB) in
+`/mnt/entropy/.AGENTTRASH/20261101-detritus-sweep`, plan `detritus-sweep-plan.tsv`,
+journal `detritus-sweep.jsonl`, 542 husks removed by `sweep`. It moved files only
+from folders whose whole subtree held no media, so it creates no stale rows and
+needs no scan. The guards that hold a folder back are the finding: external
+subtitle folders (428 of them, 6 GiB) and ripped Blu-ray streams — `.sup` PGS,
+`.thd`/`.eac3`/`.dts` audio, `.cci` captions, 25 GiB — are not trash, and an
+extension the census does not recognise is a reason to stop, not to sweep.
+
+`scripts/media-verify.py` reads differently for a prune than for a relayout:
+`landed: 0` is the **correct** end state (no server may index the hold), so the
+verdict is `still at src: 0` with `REAL: 0`, and the rows that simply vanished
+from the database are the pass succeeding.
+
+## Failure signatures
+
+| Symptom | Meaning |
+|---|---|
+| A size group whose members split under the sparse hash | The head+tail screen collided. Those files stay exactly where they are and get reported. |
+| The planner holds far fewer files than the analyzer counted | Two implementations of "largest wins". The analyzer must emit `keep`/`hold` marks and the planner only transcribes them — a planner that re-derives the winner from the hold list alone drops the keeper out of the group and prunes almost nothing. |
+| `df` unchanged after a TiB of moves | Expected: the hold is on the same filesystem. Only the purge frees space. |
+| A film that "disappeared" after a prune | It is in the hold, named by the journal: `media-apply.py rollback --journal … --apply`. |

+a relayout — a pass that moves only media files with no sidecars next to them
+leaves the upper layer untouched, and `reap` correctly finds nothing.
