Serve retained capture Evidence as a bounded MCP replay environment with discovery. Preserve default stdio, caller-selected facts and complete source Evidence. Fix numeric fidelity, argument identity, startup cancellation and bounded discovery, query/path matching and output metadata. Verify real recorded API data and public CLI/MCP workflows; preserve explicit gaps for Windows and third-party hosts.
