      summary: Run one isolated strict-lifecycle simulation
      description: Zero-account demonstration that accepts no Authorization credential and exercises the real cryptographic and lifecycle validators with fresh ephemeral keys. The request-local simulation covers challenge, strict authority, atomic reservation, provider-bound permit issuance, one successful claim, replay rejection, simulated provider evidence, COMMIT and signed execution-receipt verification. It is always test_only=true, money_moved=false and production_accepted=false. It retains no lifecycle state, accepts no user-supplied outbound URL, contacts no external provider or independent organization, and does not prove production conformance, third-party validation, audit or certification.
