- Keep (a) list/stats/pinned open SessionDB(read_only=True) — one parametrized test — and (b) a missing store prints empty results and is never created.
- Drop the insights read-only test (already covered on main), the status test, the mutating-action/live-writer/doctor-isolation tests, and the two doctor factory tests.
- Replace _EmptyObservationalStore + error-string sniffing with a plain '_default_db_path() does not exist' branch printing each action's empty output; the fake-store tests in test_sessions_pin keep working because the branch only runs when the open fails.
