A — Grouped Ledger
Projects vs ad-hoc groups, one line per session, thin context meter as an underline, hover-only close. Densest.
B — Compact Cards
Two-line cards with a plain-word state, model + project + meter on the second line. Most readable.
C — Status Lanes
Triage-first: needs-attention, working, idle lanes with counts, context as a tiny ring, idle rows demoted. Most glanceable at 20+ sessions.
