Select sessions in Session Review's pool (Ctrl/Shift-click), right-click, and move them to a group, a new group, or out of one. A cohort opened as a folder saves the groups to glider_project.json, keeping its subjects and other session fields; a broken manifest is never saved over. Sessions opened as files are grouped for the review only.
Export > Time bins (CSV) splits each session, on its own zero, into bins of 1, 3, 5, 10 or a custom number of minutes, tidy or wide, over the whole session or the selected range. The viewer's Distances chip draws the pixel distance between keypoint pairs; right-click it to choose the pairs, which are remembered per keypoint set.
Qt-free, scipy-only tests on the epoch and time-bin tables: group vs group, epoch vs epoch, group x epoch (mixed ANOVA with sphericity corrections) and trends across bins (per-animal slopes, polynomial contrasts, first vs last). Auto test selection explains its choice; effect sizes carry CIs. Reference values pinned against pingouin and scikit-posthocs.

Bin labels use a plain hyphen (0-1 min), and the window, epoch and time-bin exports are written with a UTF-8 byte-order mark, so Excel no longer shows an en dash or other non-ASCII range names as mojibake.

Three Session Review additions plus the statistics engine they feed.
1. Assign sessions to groups
Groups could only come from a hand-written
glider_project.json. Now:2. Time-bin export
Export → Time bins (CSV)…: bins of 1, 3, 5, 10 min or custom, over the whole session or the selected range, tidy (
bin,bin_start_s,bin_end_s) or wide. Each animal is binned on its own zero (flow start, else first frame); the last bin is clipped and labelled honestly. Width is remembered.3. Keypoint distances overlay
A Distances chip in the viewer draws the pixel distance between keypoint pairs. Right-click it for default pairs, all pairs, none, or individual pairs; the choice is remembered per keypoint set.
4. Statistics engine (
glider.analysis.stats, no UI yet)Qt-free, scipy-only, no new dependencies:
The Statistics tab and the "run everything" sweep come in a follow-up.
Tests
Session Review GUI, project manifest, cohort, epochs and stats suites: 635 passed. ruff and black clean.
