Audit batch 1: post-trim numbers in docs/figures.md (#3); tasks.json 2026-05-11 note + trim_offsets lookup (#5, #8); bad_frames.json trim_offsets header (#8); dataloader default which_sensors='both' (#10); new freeze_intervals.json with per-event diagnostic signals (#12)

Trim OT-uninitialized prefixes from 3 .pt files (ep_005/012/017 — see `_contact_meta.trim_offset`); recompute bad_frames + data_quality_breakdown in trimmed coords; ot_loss frame count now reflects real mid-episode mocap dropout only. Recorder-side OT watchdog added to data_collection.py (in twm repo) so future episodes won't repeat the bug.

Bake ot_loss intervals into bad_frames.json (47 events, rotation-aware detector); dataloader skips them; docs/quality + caveats updated; data_quality_breakdown #3 renamed sensor_at_rest → ot_loss

Drop 2026-03-23 right-only pilot (outdated); recompute totals across 27 bimanual recordings

Add data-quality docs: bad_frames.json, per-mode breakdown, inspection figures; refresh episode GIFs with cam2 projection overlay
