Same input, same rules

Replay

Replay the same input, state, and fork rules against the canonical result. Demo 01 synthetic, Demo 04 mainnet ETH, Demo 05 contract COMPLETE, Demo 06 ERC20-shaped synthetic — 04/05/06 are CI MATCH. Default POST is fixture; backend=revm is the hosted engine.

Fixture JSON POST or backend=revm live path. Hash-only bodies are not replayed.

Fixture / live submit

POST /v1/replay. Default is fixture. backend=revm is live REVM when the binary is hosted. Hash-only is UNSUPPORTED.
