Validate with replay

Validation sequence

Run schema, safety, evidence, and replay checks.

• The response matches the proposal schema.
• Every operation is supported and within policy.
• Evidence references belong to the incident.
• The candidate produces the expected replay result.

Compare results

Review original and candidate outcomes.

Compare the original outcome, candidate outcome, and deterministic check results. A fluent explanation does not compensate for a failed replay.

Failed validation

Keep unsafe or unsupported proposals unavailable for approval.

Seamward keeps a failed or unsafe proposal unavailable for approval. Generate a new proposal only after the underlying evidence or provider output has changed.
