Stage370: Runner Safety Brake Test Gate

Stage370 adds a runner safety brake test gate on top of Stage369.

Purpose

Stage369 created the real timestamp verifier runner with production receipt generation.

Stage370 tests whether the runner fails safely before real timestamp verification success is accepted.

Core Decision

• safety_test_pass
• safety_test_failed
• block

Meaning

Stage370 is not the final timestamp acceptance gate.

It confirms:

• bad commands are rejected
• missing metadata is rejected
• fake verified claims are blocked
• raw timestamp binary references are blocked
• timestamp_verified is not final-accepted here

Safety Boundary

Stage370 does not publish:

• private keys
• raw secrets
• raw QKD key material
• raw timestamp binaries
• exploit code
• harmful prompt payloads
• attack automation

Stage370 does not verify Sigstore, Rekor, OCSP, or CRL.
