DisplayMixin in _display.py takes the methods that reach widgets only through
self._widgets: apply, _play, _verdict, on_undo, on_quit, drain, refresh, tick
and attach_player.
Widget construction stays in ui.py on purpose. test_ui.py fakes the toolkit
with patch.object(ui, "tk", fake), so moving _build out makes 22 tests error
with "module ui does not have the attribute 'tk'". An earlier attempt did that
and was reverted rather than touching the tests.
Also dropped the four _key_* adapters; each only discarded Tk's event argument
before forwarding, so _bind_keys binds lambdas directly now.
One thing worth knowing for the next split: ruff's TC001 is NOT suppressed by
__all__ the way F401 is. Moving Callbacks to its own module and re-exporting it
left a TYPE_CHECKING-only import that lints clean and raises AttributeError at
runtime -- cli.py constructs ui.Callbacks. Reverted; it stays defined in ui.py.
ui.py 398 -> 242, _display.py 179. 277 tests pass, both files 100% covered.

New package. Walks every thread on 4chan's /wsg/, downloads each video it has
not seen, and reviews them one at a time: mpv embedded in a Tk window via --wid
with Keep/Pass/Undo directly beneath the picture.
Dedupe is structural rather than a convention. Every post carrying a file also
carries md5 -- base64 MD5 of the whole file -- so it is the sqlite primary key.
An already-seen video costs zero bytes to skip and a byte-identical repost in
another thread collapses onto the existing row. Verified against a live file:
the API's Nz9OEKdMuMZEdYE6eLTKmA== matched base64(md5(bytes)) exactly.
Undo is unbounded and survives quitting: the verdict trail lives in the index,
not in memory, so yesterday's decisions can still be taken back.
No downloaded video is ever deleted. A pass moves the file to trash/ and leaves
it there; files.apply_move refuses to overwrite an existing destination, so the
guarantee holds by construction rather than per caller.
Three bugs only running it could find, each caught from evidence rather than
guesswork:
- the video stayed black: a <Configure> handler set mpv's geometry, fighting
the automatic sizing --wid already does
- playback never advanced: refresh() ran every tick and re-sent loadfile ~7x
a second, restarting the video continuously
- it froze on one video around the 26th while filenames kept advancing: mpv
pushes an event stream down the same socket and nothing drained it, so the
buffer filled and mpv stopped reading commands. Isolated to command #35
without a drain thread; all 60 honoured with one.
A five-lens review then found nine more, all reproduced before fixing: a failed
mpv start stranded the non-daemon worker forever; undo could clobber a file in
incoming/; a NUL-bearing md5 poisoned the index permanently; an oversized int
killed the worker with no event; gzip bombs on both hosts were accepted; the
board endpoints were fetched unconditionally forever; and Session.missing could
corrupt the undo trail.
mpv runs as a subprocess over its JSON IPC socket rather than via python-mpv,
which resolves libmpv at import time and would fail on CI while passing here.
Third-party surface is requests alone, already declared.
277 package tests, 100% branch coverage on all 22 modules, no suppressions.
