Make the hash-floor gate deterministic (V-718)

Owner explicitly requested direct commits to master. Keep startup cost benchmarked without turning ambient race/coverage load into a correctness failure; record live reminder proof, stale-task reconciliation, and the temporary delegation quota caveat.
