Move 26 bookmark/save/library/batch/blacklist methods and _batch_dest
state into gui/post_actions.py. Rewire 8 signal connections and update
popout_controller signal targets.
Extract is_batch_message and is_in_library as pure functions for
Phase 2 tests. main_window.py: 1935 -> 1400 lines.
behavior change: none
Move 5 popout lifecycle methods (_open_fullscreen_preview,
_on_fullscreen_closed, _navigate_fullscreen, _update_fullscreen,
_update_fullscreen_state) and 4 state attributes (_fullscreen_window,
_popout_active, _info_was_visible, _right_splitter_sizes) into
gui/popout_controller.py.
Rename pass across ALL gui/ files: self._fullscreen_window ->
self._popout_ctrl.window (or self._app._popout_ctrl.window in other
controllers), self._popout_active -> self._popout_ctrl.is_active.
Zero remaining references outside popout_controller.py.

behavior change: none
These two methods were accidentally deleted in the commit 4 line-range
removal (they lived between _set_preview_media and _on_image_done).
Restored from pre-commit-4 state.
behavior change: none (restores lost code)
Move 10 media loading methods (_on_post_activated, _on_image_done,
_on_video_stream, _on_download_progress, _set_preview_media,
_prefetch_adjacent, _on_prefetch_progress, _auto_evict_cache,
_image_dimensions) and _prefetch_pause state into
gui/media_controller.py.

Move 21 search/pagination/scroll/blacklist methods and 8 state
attributes (_current_page, _current_tags, _current_rating, _min_score,
_loading, _search, _last_scroll_page, _infinite_scroll) into
gui/search_controller.py.
Extract pure functions for Phase 2 tests: build_search_tags,
filter_posts, should_backfill. Replace inline _filter closures with
calls to the module-level filter_posts function.
Rewire 11 signal connections and update _on_site_changed,
_on_rating_changed, _navigate_preview, _apply_settings to use the
controller. main_window.py: 3068 -> 2525 lines.
behavior change: none
Move _toggle_privacy and its lazy state (_privacy_on, _privacy_overlay,
_popout_was_visible) into gui/privacy.py. Rewire menu action, popout
signal, resizeEvent, and keyPressEvent to use the controller.
No behavior change. main_window.py: 3111 -> 3068 lines.
delete_site() leaked rows in tag_types, search_history, and
saved_searches; reconcile_library_meta() was implemented but never
called. Add tests for both fixes plus tag cache pruning.
Popout now has a full context menu matching the embedded preview:
Bookmark as (folder submenu) / Unbookmark, Save to Library (folder
submenu), Unsave, Copy File, Open in Default App, Open in Browser,
Reset View (images), and Close Popout. Signals wired to the same
main_window handlers as the embedded preview.
behavior change: right-click context menu now shows "Unbookmark" when
the post is already bookmarked, and "Bookmark as" with a folder submenu
(Unfiled / existing folders / + New Folder) when not. Previously showed
a stateless "Bookmark" action regardless of state.

Library thumbnails are saved by post_id (_copy_library_thumb uses
f"{post.id}.jpg") but the library viewer looked them up by file
stem (f"{filepath.stem}.jpg"). For digit-stem files (12345.jpg)
these are the same. For templated files (artist_12345.jpg) the
stem is "artist_12345" which doesn't match the thumbnail named
"12345.jpg" — wrong or missing thumbnails.
Fix: resolve post_id from the filename via
get_library_post_id_by_filename, then look up the thumbnail as
f"{post_id}.jpg". Generated thumbnails (for files without a
cached browse thumbnail) also store by post_id now, so
everything stays consistent.
The tag search filter in refresh() used f.stem.isdigit() to
extract post_id — templated filenames like artist_12345.jpg
failed the check and got filtered out even when their post_id
matched the search query.
Fix: look up post_id via db.get_library_post_id_by_filename
first (handles templated filenames), fall back to int(stem) for
legacy digit-stem files. Same pattern as the delete and saved-dot
fixes from earlier in this refactor.
Logs when GL render context is actually initialized (not on the no-op
path). Confirms GL init fires once per widget lifetime, not on every
video click. Kept permanently for future debugging.
behavior change: when streaming=True (uncached video handed directly to
mpv), _load now early-returns instead of running download_image in
parallel. mpv's stream-record option (added in the previous commit)
handles cache population, so the parallel httpx download was a second
TCP+TLS connection to the same CDN URL contending with mpv for
bandwidth. Single connection per uncached video after this commit.
Replaces the parallel httpx download with mpv's stream-record per-file
option. When play_file receives an HTTP URL, it passes stream_record
pointing at a .part temp file alongside the URL. mpv writes the incoming
network stream to disk as it decodes, so a single HTTP connection serves
both playback and cache population.
On clean EOF the .part is promoted to the real cache path via os.replace.
Seeks invalidate the recording (mpv may skip byte ranges), so
_seeked_during_record flags it for discard. stop() and rapid-click
cleanup also discard incomplete .part files.
At this commit both pipelines are active — _load still runs the httpx
download in parallel. Whichever finishes second wins os.replace. The
next commit removes the httpx path.
Prevents cache eviction from deleting a .part temp file that mpv's
stream-record is actively writing to. Prerequisite for the stream-record
plumbing in video_player.py.
behavior change: mpv now uses explicit cache=yes, cache_pause=no
(stutter over pause for short clips), 50MiB demuxer buffer cap,
20s read-ahead, and 10s network timeout (down from ~60s default).
Improves first-frame latency on uncached video streams and surfaces
stalled-connection errors faster.
behavior change: _apply_load_video now switches the stack to the video
surface BEFORE calling play_file so mpv's first frame lands on a visible
widget instead of a cleared image viewer. Removes the redundant stop()
call — loadfile("replace") atomically replaces the current file.
Also fixes video position not surviving popout close: StopMedia (part of
CloseRequested effects) destroyed mpv's time_pos before get_video_state
could read it. Now closeEvent snapshots position_ms before dispatching
CloseRequested, and get_video_state returns the snapshot.
behavior change: _on_video_stream no longer calls stop() on the
embedded preview's mpv when the popout is the visible target. The
embedded preview is hidden and idle — the synchronous command('stop')
round-trip was wasting ~50-100ms on the click-to-first-frame critical
path with no visible benefit. loadfile("replace") in the popout's
play_file handles the media swap atomically.
Library items' Post objects were constructed without width/height
(library_meta doesn't store them), so the popout got 0/0 and
_fit_to_content returned early without setting keep_aspect_ratio.
Videos were unaffected because mpv reports dimensions later via
VideoSizeKnown. Images had no second chance — the aspect lock
was never set, and manual window resizing stretched them freely.
Fix: new _image_dimensions(path) reads the actual pixel size from
the file via QPixmap before constructing the Post. The Post now
carries real width/height. _update_fullscreen moved to run AFTER
Post construction so cp.width/cp.height are populated when the
popout reads them for pre-fit + aspect lock.
Not a regression from the templates refactor — pre-existing gap
in the library display path.
The flag was set in _ensure_post_categories_async which runs AFTER
_on_post_selected calls info_panel.set_post. By the time the flag
was True, the flat tags had already rendered. The flash persisted.
Fix: check whether a fetch is needed and set the flag in
_on_post_selected, right before set_post. The info panel sees the
flag and skips the flat-tag fallback on its first render.
When a category fetch is about to fire (Rule34/Safebooru.org/
Moebooru on first click), the info panel was rendering the full
flat tag list, then ~200ms later re-rendering with categorized
tags. The re-layout from flat→categorized looked like a visual
hitch.
Fix: new _categories_pending flag on InfoPanel. When True, the
flat-tag fallback branch is skipped — the tags area stays empty
until categories arrive and render in one clean pass.
_ensure_post_categories_async sets _categories_pending = True
before scheduling the fetch (or False if no fetcher = Danbooru)
_on_categories_updated clears _categories_pending = False
Visual result:
Danbooru/e621: instant (inline, no flag)
Gelbooru with auth: instant (background prefetch beat the click)
Rule34/SB.org/Moebooru: empty ~200ms → categories appear cleanly
(no flat→categorized re-layout)
