Fact 57
On May 30, 2023, Alex Valdez closed the shard-keeper rollback-path fix: rollback now uses one command instead of three coordinated commands, avoiding timing-related half-reverted states and making operation safer for humans during overnight incidents; it stayed clean in four consecutive staging runs.

closed the shard-keeper rollback path fix today, May 30. this was the last ugly follow-up from the audit side that i actually cared about. before it needed three coordinated commands and you could still end up half-reverted if timing got weird; now it's one command and staging stayed clean 4x in a row. much better shape for humans at 2am. also means the migration restart isn't blocked on this anymore, which was the whole point.
