The context menu hit test only searched the current folder's markers.
Now also checks other-folder markers so the delete option appears
for subprofile markers.

Subprofile/subfolder exports now appear as colored markers (yellow,
green, blue, purple, orange) with their own numbering, separate from
the main folder's red markers. Each folder gets its own color and
independent sequence numbers.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Subprofile exports (folder_suffix) created markers that interleaved
with main folder markers, shifting their numbering. Now get_markers
and _get_markers_for accept an export_folder parameter and use
SQL LIKE to only return markers whose output_path is in that folder.

Thin 8px scrollbar appears above the ruler when the timeline is zoomed.
Shows a draggable thumb representing the current view window. Click
outside the thumb to jump, drag the thumb to pan. Ruler and track
shift down to make room. Scrollbar hidden when not zoomed.

The marker format was extended to include clip_span but the overlap
check in _on_export still unpacked 3 values, causing a crash on export.

mpv's "absolute" seek lands on the nearest keyframe before the target,
causing playback to start ~3s before the marker. Switch to
"absolute+exact" for both seek() and play_loop() so playback starts
at the precise requested time.

Revert span opacity back to 35 (was fine). The actual issue was the
play position line disappearing when scrolled out of the zoomed view.
Now set_play_position auto-pans the view window to keep the playback
marker visible with a 10% margin.

- _on_marker_clicked now explicitly sets cursor and seeks mpv to start_time
instead of relying on the timeline's indirect seek chain
- Doubled clip span area opacity (35 → 70) so spans are always visible
- Trigger end-frame preview after config restoration on marker click

- Per-profile playlist persistence (session_files/{profile} in QSettings)
- Training data resolves source videos via playlist paths before fallback dir
- Guard against deleted video files in _load_file
- Fix marker double-click to seek to exact marker time instead of click pixel
- Show manual clip spans as light amber areas on the timeline
- Extend marker tuples with clip_span from DB (clip_duration + overlap)
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add clip duration spinner (2–30s, default 8s) replacing all hardcoded
8.0 references. Store clip_duration in DB for accurate re-export span
calculations. Add x2/x4 playback speed toggle buttons. On Windows, mpv
renders directly into the widget's native window handle (WId embedding)
instead of slow FBO readback; crop overlays use a transparent child
widget. Fix _poll_render crash when player is None after closeEvent.

Re-export dialog now offers two modes: keep section length (adjust clip
count) or keep clip count (adjust section length). Files shared with
other profiles are preserved during re-export. Vid folder is resolved
before DB deletions to reuse existing folders. Add delete profile option
with confirmation dialog. Profile duplication now copies all tables
including processed exports.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Re-export button (next to Spread spinner) re-exports all manual clips
for the current file into the current folder with the new spread value.
Old files are deleted from their original locations first.
Duplicate profile option in the profile dropdown copies scan_results,
hard_negatives, and hidden_files to a new profile name (exports are not
copied since they reference file paths tied to the source profile).
Also widened get_profiles() to include profiles that only have
scan_results or hard_negatives, not just exports.

When a scan result row is clicked, if the active region falls outside
the current zoomed view the view centers on the region (and widens if
the region is larger than the current span).

Ctrl+scroll zooms the timeline view around the mouse. Middle-mouse drag
pans when zoomed. Scrolling all the way out clamps back to full view.
While dragging a scan region edge with Shift, the view auto-pans when
the mouse approaches the widget border so you can extend a region past
the visible range.
All paint and hit-test paths now route through _time_to_x / _pos_to_time
helpers backed by a _view_start / _view_span window, so existing
interactions (seek, marker click, edge resize, keyframe context menu)
all adapt naturally to the zoom level.

Add "Merge N rows" context-menu option that combines selected scan rows
into one (min start, max end, max score), with full undo support.
Ctrl+Z is now an application-wide shortcut so it works regardless of
which widget has focus. Negatives undo now respects the exported-green
row color instead of reverting to default.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- Scan panel button now reads "Export Selected (N)" while rows are
selected, mirroring the clip-count estimate used for full exports.
Selection changes fire an explicit signal so the label refreshes.
- Export markers remain visible on the timeline in scan/review mode.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- Right-click on exported (green) rows shows "Delete export" to wipe
associated clip files, annotations, DB rows and empty vid folders;
scan panel, markers and playlist badge refresh afterwards.
- Exporting with rows selected in the scan panel now runs a partial
export: prior scan exports are preserved, and the area index for new
clip filenames is offset past existing a-suffixes in the vid folder
to avoid collisions.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Scan panel rows whose range contains an exported clip's start time
are colored green. Priority: disabled > negative > exported > default.
Exported state refreshes automatically after an auto-export batch
completes on the current file.

Draws a yellow outline around the scan region corresponding to the
selected/clicked row, so overlapping regions can be distinguished.

Time column click still seeks to clip start. End column click seeks
to end - 3s so you can preview the tail of the clip.

Waveform peaks are saved as .npy files keyed by MD5 of the video
path. Subsequent loads of the same video read from cache instead
of re-running ffmpeg extraction.

When the current item is deselected via Ctrl+click, fall back to
the last remaining selected item instead of staying on the
deselected row.

Was using selectedItems()[0] which always returns the first item in
the selection, not the most recently clicked one. Changed to
currentItem() which tracks the last clicked row.

When starting a scan export batch, delete old scan_export entries for
the same file+profile before writing new ones. Logs a warning when
replacing. Prevents stale entry buildup from repeated scan exports.

Queue scan exports back-to-back: when an export is running, new
batches are queued and drain automatically on completion. Each batch
snapshots its state (file path, jobs, settings) so the user can
switch videos while exports run.
Also updates ScanWorker default and slider initial value to 0.50
to match the core threshold change.

Manual clips now follow the same pattern as scan exports:
clip_003_m1_0.mp4 (manual) vs clip_003_a1_0.mp4 (auto-scan).
The clip number matches the vid folder number.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
clip_001_a1_0 now matches vid_001 instead of using an independent
counter that created confusing double numbering.

load_for_file and add_scan_results triggered N redundant timeline repaints
via tab_changed → _on_scan_regions_edited for each tab add/remove.
blockSignals(True) during programmatic tab operations eliminates the cascade.
Also adds EAT_LARGE embedding model (1024-dim) and updates design docs.

tab_changed was only updating export count, not the timeline overlay.

New HardNegativesDialog shows all hard negatives in a table with model
filter dropdown, multi-select delete, and clear all. Accessible from
TrainDialog via "Manage..." button next to the hard negatives checkbox.

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.

Each model tab now has a version combo showing scan history. When multiple
versions exist for a (file, model), users can switch between them to
compare results across training iterations. Added _current_table() and
_tab_table() helpers to unwrap the new container→table widget hierarchy.
