#1029 (ru catalogue keys) is on main; this branch has origin/main merged in (signed-off merge commit) and every gate below ran on the committed tree.

What

A Plex "Other Videos" library (type movie, agent tv.plex.agents.none, scanner Plex Video Files) is no longer folded
into Movies. It gets its own Other Videos pill after TV Shows, its own Library page (grid, A-Z rail, Sort & Filter with
Plays, Recommended, Collections), its own Sources list and its own Favorite-libraries switch. Switching the library off
removes only that pill. The pill reads the library's own name when it is the only Other Videos library you follow, and
the translated "Other Videos" otherwise.

Why

The app classified a section by its Plex type alone, so Other Videos (type movie) was a Movies library. agent and
scanner are in the same plain /library/sections answer.

How

• LibrarySection reads agent and scanner; is_other_videos() = movie AND a "none" agent AND a scanner starting with
  Plex Video Files (case-insensitive; the legacy com.plexapp.agents.none / Plex Video Files Scanner too). A curated
  Movies library (Movie scanner), a Movie agent with the Video Files scanner, and a server that sends neither field all
  stay Movies: a false negative is today's behaviour, a false positive would move a curated library off its pill.
• SecKind::Video (app code "video": additive in last_library, rollback-safe; Movie 0 / Show 1 keep their canon
  codes, so SCREEN_SHAPES_PIN and the replay anchors do not move).
• One HomeTab <-> strip key <-> section kind mapping replaces six hand-written copies; Search and Watchlist ended
  theirs in a silent fallthrough and would not have pressed a new pill. Strip keys are declared by one strip_keys!
  macro with a compile-time pairwise-distinct assert; TAB_KEY_VIDEOS = STRIP_BASE + 7 (open Live TV: watch the server's channels, and a TV tab of channel covers #993 holds +6).
• Home follows the server's visibility: a library the owner hid from the home screen (hidden 1 or 2, verified values)
  sends no Home row, so its pill is the way in; a visible one (hidden 0) gets its home.videos.recent row (a hub of
  type clip whose items are movie rows). Personal-video hubs (home.videos.*, video.*) never feed the recently-added families' hero allowance and pool (one predicate in both places that spend it; an in-progress clip still reaches the hero through Continue Watching).
• The pill's label is the library's own server title when exactly one favourite Other Videos library exists
  (DirectoryView::tab_library_title, one rule, sole_favorite_title, shared by the table and the view). The title is server text,
  never translated: control characters become spaces, characters that draw nothing (zero-width, bidi, soft hyphen, BOM) are
  dropped, white space collapses, at most 128 characters are kept, and it is elided by character to the room the strip leaves
  (widgets::fit_title_face: 904 px of strip content keeps the unfurled profile chip its pinned 290 px, so the text budget is
  240 px (en de es fr it pt), 209 (hu), 202 (ru), 189 (be); below a 60 px floor the translated word is used). Two or more favourite
  libraries, an empty or control-only title, or a title equal to another pill's label (Unicode lowercase, so ФИЛЬМЫ is
  Фильмы) keep the translated word. Movies and TV Shows keep their type words, and so do the Type menu and the counts.
  tabs_gen moves when the title does (BrowseState::tab_titles, stamped beside the pill mask), and append_sections_with now
  takes a new title for a section it already holds (a blank rename is ignored), so a server rename shows after the next
  rediscovery (restart, profile or server switch, Sources "Re-check"; nothing polls). A library deleted on the server stays until
  restart, as before.
• A friend's Other Videos library stays Off in Favorite libraries by default (household_type is true for Video), so a
  friend's personal clips never reach a household's Home unasked; the household's own is On.
• i18n: four keys in all nine locales. Mock PMS: opt-in --other-videos N (+ --other-videos-hidden, --other-videos-title NAME,
  --other-videos-sections K, and POST /_mock/config {"section_titles": {...}} to stage a rename), default off.

Verified

Real PMS 1.43.5 (GET only, read-only): section fields (agent, scanner, hidden), hub types and ids, the hidden
values 0/1/2 via the library's prefs, listing / sort (incl. viewCount) / collections.

Red then green (details: commit messages): C4 a_three_section_answer_projects_movies_shows_and_other_videos
((3, "Other Videos", Movie) vs Video), C6 the clip-hub tests (hub count 0 vs 1; hero allowance 5 vs 8; with only the
hub gate opened the hero pool was ["901","902","1"], with the predicate ["1"]).

Gates on the committed tree (clean git status, origin/main merged in):
make check-cargo exit 0 (test result: ok. 1073 passed app default features, 1186 passed app hostsim, plx_data 1279, plx_ui 1406,
plx_screens 1720, plx_plex 738, plx_platform 288, plx_appkit 347, plx_media 1744/1906 default/hostsim; 0 failed), make check-python-harness

tests/replay_fixtures.py against the hostsim build (3 fixtures, 6 replays, 0 failures, verdict=SAME; no replay anchor or SCREEN_SHAPES_PIN moved).
make check as a whole stops at ci/test_disk_preflight.py (free disk space of the machine it ran on; unrelated).

Red then green for the pill title: the ten other_videos_pill tests (e.g. left: "Other Videos" vs right: "Home Movies"; the face
did not end in the ellipsis; "Фильмы 2" vs the type word), the rename test (left: "Home Movies" vs right: "Family Clips"), and compile errors
for the new accessors.

Simulator (1280x720, mock --other-videos 24; browse and UI only, no host FFmpeg): the strip with Home, Movies, TV Shows,
Other Videos, bookmark, Search; the Other Videos Library grid and its Sort & Filter (no "Show" section, Plays present);
Recommended page with the video.* shelves; Home row "Recently Added Videos" with a visible library and none with
--other-videos-hidden (pill present either way); the pill pressed from Search; a clip's detail page (no error line);
the count noun "24 videos" in Favorite libraries; de, ru, be and the pseudo-locale strip.

Pill title (mock --other-videos-title, 1280x720): one library "Home Movies" reads Home Movies; a 62-character title reads Family holidays...;
"Andere Videos" as a title is whole; two libraries read the type word; nine libraries read the type word and the Library header names them,
and after POST /_mock/config {"section_titles": ...} plus "Check for shared libraries" the header shows the new names without a restart;
in ru and be a 42-character title is elided (Family video..., Family vide...); in de a one-word title (Clips) draws the glass track and a long one the flat
capsule, as the model says. Movies and TV Shows are unchanged in every run. A rename of the pill itself in one process (as opposed to the header)
is covered by the data tests only.

Notes

• Glass: the top track wears the glass material only up to a 672.3 px budget (tab_glass_on). On the shipped font's advances (a model of the
  television's text, not a television measurement) the two-type track is 621 px in English and 529-679 px across the shipped languages (Belarusian is
  already over the budget today). The translated "Other Videos" label makes the strip flat in every language; a library title keeps the glass only if its text
  is at most 91 px in German, 71 Portuguese, 65 Italian, 59 French, 38 Spanish (never in English, Hungarian, Russian, Belarusian). Pinned by
  the_two_type_track_is_measured_per_language_against_the_budget, the_translated_other_videos_pill_is_flat_in_every_language
  and a_library_title_keeps_the_glass_only_where_the_track_has_room; look at it on a TV. A rename can flip glass and flat
  in the five languages with room (de pt it fr es).
• The pill title: server text, so it is not translated and not in any catalogue; elided to 189-240 px of text depending on the
  UI language so the chip keeps its 290 px (a 197 px title such as German "Andere Videos" is whole in every language but
  Belarusian); a rename shows after the next rediscovery, a deleted library stays until restart (both pre-existing limits
  of an append-only table); Arabic and Hebrew titles have no glyph in any shipped face (Arabic and Hebrew text in the UI (titles, track names, menus) #760, UI text: Arabic and Hebrew with RTL paragraphs #1007), while CJK and emoji
  titles draw through the bundled fallback faces (the elision is by character, so it can cut an emoji sequence or a combining
  mark: a plain prefix and the ellipsis remain). The Type menu and counts say "Other Videos"/"videos" even when the pill reads
  "Home Videos".
• Commit subject: d5f5894e says "Other Videos never feed the hero"; what it does (and what the code comment now says) is
  that personal-video hubs never feed the recently-added families' hero allowance and pool. History is not rewritten.
• Chip: the unfurled profile chip clears the track for names up to 294 px in Russian (the tightest; English 326, the
  name budget is 320); wider names overlap by at most 26 px while the chip, being focused, draws on top.
• Fixture recipe: tests/fixtures/README.md and make_fixtures.py now say to keep the integration Movies library on the
  Plex Movie scanner. A library scanned with Plex Video Files is Other Videos to the app, which would move these
  real-PMS scenes off the Movies pill (those that arm plxnative-library as true/"0" and the Movies-pill routes in
  tests/manifest.json): poster-scroll-settle, poster-eviction-reversal, library-grid-paging-held-3g,
  library-grid-paging-held-remote-wan, library-shelf-paging-held-3g, library-shelf-paging-held-remote-wan,
  library-shelves-deep, library-burst, library-hold, library-scroll, library-collections, library-recommended,
  library-switch, library-idle. A maintainer whose library already uses the Video Files scanner re-scans it as Plex Movie
  or uses plxnative-library=2. The mock suites are unaffected (opt-in flag).
• Behaviour note: a user who deliberately keeps films in an Other Videos library now finds them under the Other Videos pill.
• Cross-PR: strip key STRIP_BASE + 7 (a compile-time assert refuses two destinations on one key whichever of Live TV: watch the server's channels, and a TV tab of channel covers #993 and
  this lands first); UI text: Arabic and Hebrew with RTL paragraphs #1007 (Arabic/Hebrew) will need these four keys in its two extra locales on rebase.
• Not verified: the item type inside a visible library's global home.videos.recent hub (the measured library was
  hidden; if the items are clip-typed the row is empty and dropped, no crash); a friend's shared-token section row
  (agent/scanner present?; absent reads as Movies); the television (flat track, pill fit, chip overlap); playback of a
  clip; the Favorite-libraries switch in the simulator (a signed-out boot has no Favorite-libraries editor, so
  that step is covered by switching_the_other_videos_favourite_off_takes_only_its_pill only); with a visible library an
  in-progress clip reaches the hero through Continue Watching (the deck, not the excluded recently-added families).
• Translations: English is the source. German "Andere Videos" is Plex's own label for the library type and is now only
  the fallback pill label, used when there are two libraries or the title is unusable (the German reviewer is asked to confirm it). Needs a native reviewer: es "Otros vídeos" (the existing es hub title says
  "Vídeos caseros": two words for one family, please harmonise), fr "Autres vidéos", it "Altri video", pt "Outros vídeos",
  hu "Egyéb videók", ru "Другие видео" and be "Іншае відэа" (the be strings are on the "Pending native review" list of
  docs/localization-belarusian-review.md). Keys: browse.kind.other_videos, browse.kind.videos,
  browse.library.videos, browse.library.no_videos.

Closes #599
