Step-by-step answer
Stretch 2 hours7 stepsRoll out a prompt by matter, with shadow runs
A standard-library simulation of a matter-keyed rollout. A SQLite system of record, a release config, a stable hash that assigns each new matter a prompt version once and journals it, shadow runs that store the candidate's output without sending it, a month of 400 synthetic matters, and a bad-release drill that finds, cancels and restarts affected runs and lists the emails rollback can't recall.
