Roll out by
the notch.
Schedule a change from 1% to everyone, watch the metrics between each step and hold automatically when they slip.

01
Schedules, not spreadsheets.
Define steps and hold times once. Rheostat moves the dial and posts every step to your channel.
02
Guardrails at every notch.
Latency, errors, conversion or any warehouse metric — each step waits until they look right.
03
Rollback is one rule away.
If a guardrail fails, the change drops to 0% in under a second. No redeploy, no pager.
