Production readiness checklist

Checklist is guidance, not a certification. Passing it is necessary but not sufficient for your plant.
#GateWhy
1Strictly positive inputs (or safe offset)Log-space identity
2x* policy documented (frozen vs adaptive)Wrong normal moves the mean
3Shadow run vs EMA on your dataLocked packs ≠ your plant
4Delay audit if any command pathMulti-minute delay is a red light
5Alarms/detectors not forced through GSRF residualFixed-FA residual is a non-claim
6MAD tracking not the sole KPISpring costs tracking by design
7Commercial license executedSnippet ≠ production grant
8Rollback path + monitoring of filter outputsOperational hygiene

Pricing: customers. Limits: safety cage. Losses: when GSRF lost.

Questions people actually ask

Is the Try snippet production-ready?

No. Evaluation only. Production requires a commercial license and your acceptance tests.

What is the #1 go-live blocker we see conceptually?

Using GSRF as a delayed closed-loop command smoother or as a fixed-FA residual detector — both are published red lights.

Do I need adaptive x* in production?

Only if operating point permanently moves. Adaptive helps multi-regime traces; can hurt flat SpO2-like series. Document the policy.
