DAILY RESEARCH REPORTBACK TO MASTER SHEET2026-03-20- **2026-03-20** (formerly missing) — now renders 9 test rows, headline `val_bpb`. Row dates and source records check out via `render_day.best_date`. (All 9 rows are `commit_only_metric` warnings; see Suspect Rows.)
| 2026-03-20 | 9 | 9 |
- **date:** 2026-03-20
- **exact evidence:** SQLite `metrics_json` shows `{"val_bpb": 1.1428, "val_bpb_source": "commit_message"}`. `audit_daily_accuracy.is_commit_only` returned True (only sources for the row are `git_commit` rows). `render_day.best_date(rec) == "2026-03-20"` matches the page; `mtime_iso = 2026-03-21T00:04:49Z` is correctly converted to local CDT 2026-03-20.{
