Script used calendar-day duration (end_date - init_date), which
inflated tracks that sat dormant between work and archive-move.
Example: external_editor_integration_20260308 reported 60 days
(init 2026-03-08, last archive-move 2026-05-07) when actual work
was 2 active days.
Corrected metric: active days = distinct calendar days with at
least one commit touching the track folder. All 30 top tracks
now show 2-7 active days, matching the user's expectation that
no track lasts more than a week.
Also fixed commit_count + files_touched for all 30 tracks (the
script's work-prefix-only count was always 0-1 for these).
Top 3 examples:
- external_editor_integration_20260308: 60d/1c/4f -> 2d/4c/8f
- code_path_audit_20260607: 18d/1c/7f -> 7d/23c/14f
- nagent_review_20260608: 12d/0c/20f -> 3d/53c/20f
Still stale (need recompute, not hand-fix):
- 3.1 per-era aggregates
- 8 use-case predictions
- 218 other tracks not in top-30
