Proof Chain Verification

Commands

wrkr verify --chain --json
wrkr evidence --frameworks eu-ai-act,soc2 --output ./.tmp/evidence --json
wrkr verify --chain --state ./.tmp/state.json --json

Expected JSON keys

• status
• chain
• chain.intact
• chain.head_hash

Exit codes

• 0: chain intact
• 2: verification failure

Notes

Proof verification is local and deterministic. Verification failures are blocking contract signals.

Q&A

Which JSON keys should automation parse after verification?

Parse status, chain, chain.intact, and chain.head_hash as the core verification contract fields.

What exit code indicates proof-chain failure?

Exit code 2 indicates verification failure and should fail CI immediately.

How do I gate merges on proof integrity?

Run wrkr verify --chain --json in CI and require exit code 0 before continuing to promotion or merge.
