feat: Add E2E zkVM proof tests with RISC Zero integration#11
Merged
Conversation
- Add methods crate for building zkVM guest ELF and exporting IMAGE_ID - Add zkvm-guest wrapper crate for risc0-build compatibility - Add e2e-tests crate with feature-gated proof generation tests - Add agent code hash binding (build.rs generates AGENT_CODE_HASH) - Add spec/e2e-tests.md specification document - Update README with E2E testing and on-chain verification sections Test cases: - test_e2e_success_with_echo: Happy path with proof generation - test_e2e_agent_code_hash_mismatch: Security validation - test_e2e_empty_output: Empty output commitment verification - test_e2e_determinism: Deterministic execution verification On-chain data extraction: - seal (256 bytes Groth16 proof) - journal (KernelJournalV1 bytes) - imageId (bytes32 guest identity)
