WORLDLINE is a research prototype. Nothing here is accredited or certified, and all scenarios are synthetic.

• An agent or pipeline step misreporting what the pipeline computed: the kernel recomputes claims before attesting them, and a mismatch denies the release.
• Tampering with an evidence bundle after sealing: edits, drops, reordering, truncation and wrong keys produce distinct findings and deny the release.
• A release authorized on stale evidence or for a different artifact digest.

• A compromised CI runner or a leaked signing key. The private key lives only in a protected CI variable; the public key is committed at policies/kernel_public.pem. Rotate with uv run worldline keygen and update the variable.
• Weaknesses in the simulated world's model. A PASS is a statement about the declared scenario, not about any real system.
