car-ffi-common

Shared logic for Common Agent Runtime FFI bindings (NAPI + PyO3).

What it does

Pure Rust functions that accept JSON strings and return Result<String, String>. Each FFI crate (car-ffi-napi, car-ffi-pyo3) wraps these with its own error type (napi::Error, PyErr).

Why this exists: keeping the JSON-marshalling logic out of the binding crates means the NAPI and PyO3 surfaces stay thin and identical. Adding a new method to both bindings becomes "add it to car-ffi-common, then add a one-line wrapper to each binding."

Where it fits

If you're adding a CAR capability to the FFI surface, write the body here. The binding crates should be wrappers, not implementations. See crates/car-ffi-napi/src/lib.rs and crates/car-ffi-pyo3/src/lib.rs for the pattern.

Modules cover: verify, simulate, equivalent, optimize, multi-agent, scheduler, browser, voice, meeting, accounts, calendar, contacts, mail, health, permissions, secrets.
