A dedicated "♪ Extract audio" button on the transport row grabs an exact
length of audio (set via the adjacent length box, from the playhead) and opens
a Save As dialog. Output format follows the chosen extension — WAV (pcm_s16le),
MP3 (libmp3lame), FLAC, m4a/aac, ogg/opus — re-encoding as needed; unknown
extensions let ffmpeg pick from the container.
- core.ffmpeg.build_audio_clip_command(input, start, duration, out_path):
fast-seek + exact -t duration + -vn, codec by extension. Verified end-to-end
(wav/mp3/flac all land at exactly the requested duration).
- Timeline shows the audio area as a distinct teal dashed band spanning
[cursor, cursor+length], updated live as the playhead or length changes, so
you see exactly what will be extracted.
- Length + last save dir persist in QSettings; button enabled once a file loads.
Tests: 3 core (codec-by-extension, exact length, case-insensitive) + 2 GUI
(controls exist, band tracks cursor/length).

Two issues with the per-subprofile (subcategory) export buttons:
1. Visibility was decided by a fuzzy `f.endswith("_" + suffix)` match against
the hidden-subcats set. A ghost "_blowjob" (empty-base leftover from the
trailing-slash folder bug) or an unrelated "mp4_no_clap" would match and
hide the wrong button — so enabling a subcategory in the Sub menu never
revealed its export button. Match the exact "<base>_<suffix>" folder name
instead (same name the menu shows and _hidden_subcats stores).
2. The buttons were crammed into the transport row after Export. Move them to
their own row with stretches on both ends so the (often many) "▸ name"
buttons stay centered and out of the transport controls.
Also cleared the polluted hidden_subcats/POV_Front set in the user's QSettings
(ghost "_*" names + a hide-all'd set of real "mp4_*"), so every subcategory is
visible again. Regression test added for the exact-match predicate.

A folder ending in "/" made os.path.basename() return "", so subprofile
folders/labels became "_blowjob" instead of "mp4_blowjob" — cluttering the
subcategory menu and breaking the marker↔category match. rstrip the trailing
separator in _tab_export_folder and the three basename(_txt_folder) sites.

".../AlexisCrystal/" + "_copy" was producing ".../AlexisCrystal/_copy"; rstrip
the trailing separator first → ".../AlexisCrystal_copy". Regression test uses a
trailing-slash source folder.

Constructing MainWindow loads and (on close) re-saves the playlist tabs; a test
that mutated tab state could persist into the user's real session. Redirect
QSettings to a temp dir at import time.

New tab copies the source tab's video list + separators, gets a unique
"<name> copy" label and an adapted own export folder ("<folder>_copy"), and
inherits the tab-named-folder flag. No files are moved or copied — you export
into the new tab's folder. Keeps Foley/variant datasets separate without the
file-shuffling that a misexport used to require.

Pinning 2 of 3 panels previously showed a 3rd "leftover" tab-column, which
read as all-three-pinned and was confusing. Now the split view shows exactly
the pinned panels (pin 2 -> 2 columns, pin 3 -> 3). Adds an always-available
View > Side-by-side panels submenu of checkable toggles as the way to pin a
panel while already in split view (the right-click-tab gesture only works in
tabbed mode). Tests assert exactly-N-columns and the menu-pin path; the win
fixture now resets deck state so tests don't depend on persisted layout.

- test_deck_stack_exists: _deck_stack present; default shows _control_deck.
- test_pinning_two_panels_switches_to_split: pin 2 panels + refresh →
stack shows _deck_split_container.
Pin via _pinned flags directly (not the toggle handler) so no QSettings
write leaks into other function-scoped windows; existing 6 tests run in
default/tabbed state and still pass.

Add source_model column to hard_negatives table with migration. New
get_hard_negatives() returns full rows, delete_hard_negatives_by_ids()
for bulk deletion. get_training_data() gains use_hard_negatives param.
TrainDialog has "Use hard negatives" checkbox. Scan panel passes current
model name when marking negatives.

Add scan_timestamp column to scan_results. save_scan_results now inserts
with a timestamp and prunes versions beyond max_versions (default 5).
get_scan_results returns only the latest version by default, with optional
scan_timestamp parameter for loading specific versions. New get_scan_versions
method returns available versions for a (file, profile, model) tuple.

Ghost folders (scan-export-only) no longer appear in training dropdowns.
Also filters out 0-clip folders from get_training_stats.

- Fix test_utils.py importing build_annotation_json_path from main
instead of core.annotations (all 59 tests pass now)

Root cause of poor discrimination: MFCC[0] (energy) dominated the
feature vector, making cosine similarity see all audio as similar.
Changes:
- Skip MFCC[0], use 12 coefficients instead of 20
- Add delta MFCCs for temporal dynamics
- Add 7-band spectral contrast for tonal vs noise quality
- Switch from cosine similarity to euclidean-distance-based score
- Pre-compute STFT once for whole file (10-20x faster)
- Vectorized sliding window via cumulative sums (no Python loop)
- Lower sample rate 22050→16000 Hz (faster, no quality loss)
- 62-dim feature vector (was 40-dim mean+std of raw MFCCs)
- Default threshold 0.05 (new similarity scale)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Mean-only vectors were too similar across different audio segments,
causing everything to match even at threshold 0.99. Adding std
captures temporal dynamics and makes the similarity scores much
more spread out.

Adds a pure function that returns the latest keyframe at or before a
given time (with tolerance), replacing the inline lookup pattern that
appears multiple times in main.py. Includes 6 tests covering empty
list, before-first, exact match, between, after-last, and tolerance.

- Lock button (G key) freezes export cursor, timeline scrubs playback only
- In lock mode, clicking crop bar sets a keyframe at current playback time
- Orange diamonds on timeline show keyframe positions
- Export resolves per-clip crop center from nearest preceding keyframe
- Crop bar/overlay updates while scrubbing to preview effective crop
- Unlocking clears all keyframes
- Replace fuzzy filename matching with exact match to prevent marker bleed

Each profile has its own set of timeline markers, so the same video
can be cut with different settings (e.g. landscape vs portrait) without
markers interfering. Profile selector in the top bar, persisted in
QSettings, stored per-row in the DB.
- Add `profile` column to ProcessedDB schema (migrates existing rows
to 'default')
- Scope find_similar, get_markers, _get_markers_for by profile
- Add get_profiles() for populating the combo dropdown
- Thread profile through _DBWorker, _after_load, _refresh_markers,
_on_clip_done, dropEvent, _on_open_files
- Editable profile QComboBox in top bar, refreshed after each export
- 5 new tests for profile isolation and backward compatibility (54 total)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Style QComboBox/QSpinBox/QDoubleSpinBox/QCheckBox in dark theme
- Delete and overwrite now operate on the full clip group, not just one sub-clip

- Restructure control rows: transport+actions / annotation+path / encoding
- Add "Open Files" button to queue panel (replaces drag-drop-only)
- Playlist right-click to remove items
- Compact time display (1:23.4 / 5:00.0), window title shows filename
- Short side: QLineEdit → QSpinBox with validation
- Tooltips with keyboard shortcuts on all interactive widgets
- Fix arrow hint direction, remove stale mask comment

Each batch export creates a subfolder named after the group (e.g.
clip_001/) containing all sub-clips and their audio files. Keeps
the top-level export folder clean.

Each export generates clip_NNN_0, clip_NNN_1, clip_NNN_2 offset by the
spread value (2–8s, default 3s). Preview plays the full span covered by
all three clips. Marker click still overwrites a single clip.

Each exported clip writes an entry to <folder>/dataset.json containing
its relative path, sound label, and fps. Re-exporting to the same path
updates the existing entry (upsert). Empty labels are skipped.

Adds build_audio_extract_command and runs it in ExportWorker after the
frame sequence completes. Audio written to <sequence_dir>.wav (lossless
pcm_s16le). Extraction failure (no audio stream) is silently ignored.
