v0.307.0: after a restart the Databases table lists each database once, not every pre-restore undo copy
Seen on demo-hp 2026-10-10 (adventurelog x4, bookstack x4). The synthesised run skips IsUndo files; only undo copies
-> no synthesised run. Two tests, both red-proved. v0.306.0 (R-570) was built but never delivered; 0.307.0 carries it.

// After a controller restart the Backup → Apps „Databases" table is SYNTHESISED from the dump files on disk (the last
// run's result is not in memory). Seen 2026-10-10 on demo-hp after the 0.305.0 delivery: every `pre-restore-` undo copy
// (R-379) was listed as one more row of the night's run — adventurelog four times, bookstack four times, each stamped
// with the run's time. An undo copy is not part of any run: it stays in the file list (its visibility is a recorded
// decision), but the run table shows one row per database, the newest real dump.
