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)

1. Rename ScanWorker.finished → scan_done to stop shadowing
QThread.finished. Previously, cancelled scans leaked the QThread
because the custom signal was never emitted.
2. Block signals on combobox reset in _on_scan_ref_changed to
prevent re-entrant call when user cancels folder dialog.
3. Merge overlapping scan regions into clusters before S-key
navigation so it jumps to the next distinct match, not 1s forward
through overlapping windows.

When cancelling a scan during file change, connect finished signal
to deleteLater instead of calling it immediately on a running thread.

Add Scan button, threshold spinner, mode combobox, and reference source
combobox to the settings row. Implement handler methods for starting scans,
handling results/errors, cleanup of workers, and reference folder selection.

Add scan region storage and rendering to TimelineWidget:
- _scan_regions list in __init__ for (start, end, score) tuples
- set_scan_regions() and clear_scan_regions() methods
- paintEvent draws semi-transparent blue rectangles with score-based opacity

- Autoclip (A): adjusts clip count to fit current pause position
- Pause no longer resets playback position — stays where paused
- Play resumes from pause point instead of restarting
- Spread/clips changes update loop end without restarting playback
- Number keys 1-9 export to subprofiles
- Click-away clears focus from spinboxes so hotkeys work again
- Lock mode: double-click marker jumps cursor to end of clip span

- Subprofiles: lightweight export variants that append a suffix to the
export folder (e.g. _soft, _intense). Each gets its own export button
in the transport row. Managed via "+" menu, persisted in QSettings.
- Play loop now updates immediately when spread/clips spinboxes change.
- Lock mode: ignore stale mpv position updates while user is dragging
to prevent the play position from jumping back.

- setup-windows.ps1: downloads libmpv DLL and ffmpeg, installs pip deps
- 8cut.bat: double-click launcher
- main.py: add_dll_directory for libmpv next to script (not just frozen)

Enables cross-platform builds for Windows and macOS. Adds _bin() helper
to resolve bundled ffmpeg in frozen builds, and configures ctypes library
path for bundled libmpv.

Replace the bottom status bar with a right-aligned label on the
settings row, saving vertical space. Add "Export complete" message
when a batch finishes.

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.

Extended selection mode (Ctrl+click, Shift+click) enabled. Right-click
context menu adapts to selection count — hide or remove multiple files
at once. Single click without modifiers still loads the file.

Instead of hiding QListWidget items (which causes Qt to miscalculate
scroll position), the playlist now rebuilds its contents from scratch
whenever visibility changes. Only visible items exist in the widget.
- _rebuild() clears and repopulates from _paths filtered by visibility
- mark_done/unmark_done update in-place for visible items
- set_hidden_basenames and set_hide_exported trigger _rebuild
- Removes _LockedScrollBar, all scroll hacks, and workarounds
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
_LockedScrollBar subclasses QScrollBar and blocks setValue when locked.
This catches ALL scroll sources — Qt layout, auto-scroll, item changes —
not just scrollTo. Locked during setCurrentRow, visibility changes,
playlist checks, and video load (200ms after load to catch late events).

Keyframes were skipped when ratio was None (random mode), and random
crop was overwriting the resolved center with base_center. Now
keyframes resolve the center for all jobs first, then random crop
assigns the ratio while preserving the per-job center.

ExportWorker now uses Popen instead of subprocess.run so running
ffmpeg processes can be killed on cancel. Cancel button appears
between Export and worker count spinner, enabled during export.
Clips already finished before cancel are kept in the DB.

Replace timer hacks and scrollbar save/restore with a proper fix:
PlaylistWidget.scrollTo() is overridden to no-op when _scroll_locked
is set. Lock is held during setCurrentRow, visibility changes,
playlist checks, and video load — all operations where Qt's internal
auto-scroll was causing the list to jump.

mpv video surface resize triggers layout events across multiple event
loop cycles. A single deferred restore was too early.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Qt processes layout changes asynchronously, so restoring the scrollbar
immediately after _after_load was too early. Use QTimer.singleShot(0)
to restore after Qt finishes processing pending layout events.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Video load triggers layout changes (buttons, crop bar, preview window)
that cause Qt to recalculate the playlist scrollbar position. Now saves
the scroll value in _load_file and restores it at the end of _after_load.
