Simulator — not LifeFile. It encodes our reading of the LifeFile OpenAPI
spec (v1.260421.0) and cannot discover where that reading is wrong; only LifeFile's
staging certification can.
Outbound only. LifeFile's data-push (status webhook) is
not simulated: its payload format and auth are unknown until LifeFile's
registration documents arrive. A status set here is local — nothing is pushed to the
platform.
