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.

Two bugs caused vid number collisions (multiple files sharing a vid_NNN):
1. "First gap" assignment (n=1; while vid_n in existing: n++) would
reuse deleted vid numbers. Changed to max(existing) + 1 so numbers
always increase.
2. LIMIT 1 without ORDER BY returned arbitrary rows when a file had
entries in multiple vid folders. Added ORDER BY rowid DESC for
deterministic latest-wins behavior.

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.

Set CQ/QP rate control (quality 28) for NVENC, VAAPI, QSV, and AMF

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.

pip install -r requirements.txt can pull CPU-only torchvision via
transitive dependencies (timm, ultralytics). Adding --extra-index-url
with the CUDA wheel index ensures all torch packages stay on the
correct build. Applied to both Linux and Windows setup scripts.

tab_changed was only updating export count, not the timeline overlay.
Now calls _on_scan_regions_edited which refreshes both.

EAT remote model code (worstchan/EAT-base_epoch30_finetune_AS2M) is

Remove the "skip if torch exists" guard so re-running the setup script
fixes a broken torchvision install.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
timm and ultralytics depend on torchvision. When pip install -r
requirements.txt resolves them, it pulls torchvision from PyPI (CPU
build) which is incompatible with CUDA torch, causing
"operator torchvision::nms does not exist" at import time.

- Use microsecond-precision timestamps to prevent version merging on
sub-second scans
- Clear undo stack when switching scan versions (stale row references)
- Parse timestamp labels robustly instead of hard-coded string slicing
- "Clear All" in hard negatives dialog respects active model filter
- Remove time.sleep from tests (no longer needed with microsecond timestamps)

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.

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.

- Calibration: cv=min(3,n_pos,n_neg_sample) could yield cv=1 (ValueError);
replaced with min_class >= 6 guard to skip calibration for tiny datasets
- AST: clarified chunks are already numpy arrays, use list(chunks) directly
- EAT: noted extract_features returns plain tensor (not tuple)
- Multi-layer: explicit notes on _w2v_model_name storing base name,
ml_cfg needed in _extract_w2v_targeted, embeddings_list vs embeddings
- Added AST to _ml_config layer_counts upfront in Task 2
- Added integration test for model switching (no-reload verification)
