Subject: fix(video): a Specials/Bonus folder's episodes were matched to TMDB
 as unrelated standalone movies
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Found live: a "Specials" folder full of one-off-named bonus episodes had
every file appear as its own poster, matched against TMDB by its own
title, because guessit finds no season/episode grammar at all in a
filename with no SxxExx of its own — so the classification (episode vs
standalone movie), based solely on that, fell to the movie branch. Real,
unrelated films happened to share several of those one-off titles and
matched confidently, one per Special, cluttering the Videos view with
dozens of wrong posters instead of grouping under the show.

An ancestor folder saying this is part of a show — a numbered season, or
Specials/Bonus/Extras -> season 0 — is now trusted over the filename
having no SxxExx of its own. The show's name can't come from this file's
own guessit title (that's the bug) or from siblings in the same Specials
folder (every one of them has the same gap) — it's borrowed from the
show's ordinary season folders next door, which do carry it in the usual
ShowName.SxxExx shape (_title_from_show_siblings). A synthetic, stable
episode number (alphabetical rank among the folder's video files) stands
in for the real one nothing in a Specials folder provides.

Generic, not specific to a folder literally named "Specials": the same
fallback fires for any season-like ancestor folder whose files lack
per-file episode grammar, numbered seasons included (covered by a
dedicated test).

Also hardens _title_from_siblings to require the sibling's own episode
number too, not just a title — otherwise it would borrow one Special's
one-off title as if it were representative, on a folder like this one.

Existing already-indexed entries will need a rescan (restart the node) to
be re-enriched under this logic — nothing re-derives them on its own.

Subject: fix(video): TMDB match cache never invalidated on movie<->show
 reclassification
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The real reason a node restart alone didn't fix already-indexed entries
after the previous commit's enrichment change: _do_media_meta_request
checked media_cache's file->tmdb mapping (keyed by content hash) and
trusted it unconditionally, before ever comparing it against the file's
*current* movie/show classification. A file whose season/episode changed
on a later scan — exactly what the Specials-folder fix does, for every
file it reclassifies from "movie" to "tv" — kept answering with its
stale, wrong-kind-of-match forever, since nothing about a reclassification
touches this cache or its key.

Now falls through to a fresh search whenever the cached media_type
disagrees with what the entry resolves to right now, rather than trusting
a mapping that predates the file's current classification.

Subject: fix(video): group every episode under the show's own folder, not a
 per-file guessit title
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The mechanism itself was wrong, not just the TMDB matching: a bare episode
numbering convention with no show name in the filename at all
(`001    Episode's Own Title.ext`, no SxxExx, no show prefix — entirely
ordinary on its own) makes guessit invent a "title" from whatever text
follows the number. That text is the individual episode's own name, and
differs for every episode in the folder — trusting it, as the code did,
groups nothing together at all: every episode became its own single-
episode "show", searched against TMDB by that one-off title alone.

Whenever a season-like ancestor folder exists (a numbered season, or
Specials/Bonus/Extras -> season 0), its own root folder now names the show
unconditionally — never a per-file guessit title, which cannot tell a
show's real name from an individual episode's one-off name when the
filename carries no reliable ShowName/SxxExx structure. The walk continues
past *every* consecutive season-like ancestor, not just the first: a
per-season Bonus folder (Show/Season N/Bonus/file.ext) is nested two
levels inside the show, both "Bonus" and "Season N" season-like on their
own, and stopping at the first would hand back "Season N" as the show's
name instead of "Show".

Also adds "livre" ("book") to the season-word vocabulary (§3.4) — some
shows number their seasons that way (Roman numerals) rather than
"season"/"saison".

Supersedes _title_from_show_siblings from the previous commit (removed):
that fallback assumed a per-file title could still be trusted often
enough to be worth borrowing from a sibling season folder — this fix
means it never needs trusting in the first place once a season-like
ancestor exists.

Verified directly against the real library this was found on, not just
synthetic tests: every sample file (a numbered episode, a Book/Bonus
feature, a Book-root "making of") now resolves to the show's real name.

Subject: fix(video): fix two remaining bugs in Specials numbering and
 long-season episodes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

1. A season spanning more than one folder (a per-book Bonus folder nested
   inside every numbered season) got the same synthetic episode numbers
   handed out again in each folder independently — three unrelated
   Specials all showing up as "S0E01". _synthetic_episode_number now ranks
   across the whole show for the target season, not just one file's own
   folder.

2. guessit reads a bare 3-digit leading episode number as a concatenated
   season+episode guess rather than a plain episode number — "100" parses
   as season=1, episode=0, not episode=100, with nothing in its output
   distinguishing that from a real 2-digit episode. A season-like ancestor
   already overrides guessit's season (previous commit); this applies the
   same fix to episode via a direct regex on the leading number, capped at
   3 digits so a leading year (4 digits) is never misread the same way.

Both confirmed against the real library this whole fix was found on:
per-book Bonus features across two books no longer collide, and a real
100th-episode file now resolves to episode 100 instead of 0.

From bc94dc672d142e989fa4f483f643d4b43f66b02f Mon Sep 17 00:00:00 2001

Subject: fix(video): recognize "S1"/"S2"-style season folders, not just full
 words
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Found live: a real show organized its first season as "House.of.the.Dragon.
S01E01...mkv" inside a folder named "S1" (the show name embedded in every
filename, so grouping worked by guessit's own title alone), but its later
seasons as "S02E01. Episode's Own Title.mkv" inside "S2"/"S3" — no show
name in any filename at all, relying entirely on the folder. Those seasons
showed up as loose individual entries instead of grouped under the show:
season_from_folder_name only recognized "season"/"saison"/"livre" as full
words, so "S2" didn't register as a season folder at all, and the
ancestor-based show-grouping fix (previous commits) never triggered for
those seasons.

A bare "S" + 1-2 digits as the *whole* folder name is now recognized too —
anchored to the entire name so it can't match some unrelated folder that
merely starts with "s" followed by digits.

Subject: fix(video): a TMDB override never stored the metadata its chosen id
 names
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Found live: "fix match" appeared to work for two shows but not for a movie
whose own automatic search kept landing on the same wrong result. The
override only ever recorded the file->tmdb_id mapping — never the
metadata that id actually names. _do_media_meta_request's cache check
agrees the mapping is fresh (same media_type) but finds nothing under
that *new* id in tmdb_meta, since nothing had ever fetched it, and falls
through to a brand-new search using the file's own title — reproducing
the exact match the override was meant to replace.

This stayed invisible for the two shows only because their own title
happened to be enough for that fallback search to land on the right
answer anyway, entirely independent of whatever the override recorded —
never because the override was actually being honored. It surfaced on a
movie whose own title search kept landing on the same wrong match
regardless.

Fetches and stores the real metadata for the chosen tmdb_id up front (via
the existing _tmdb_build_meta, which needs only the id — no search result
object required), so a later lookup finds the override itself instead of
falling through to a search blind to it.
