What it does
- Task graphs are declared in RON and wired at compile time by a generated runtime macro.
- Execution uses a zero-allocation, data-oriented hot path aimed at realtime control.
- Runs are recorded into a unified .copper log of messages, timing, and state that can be replayed offline.
- Offers time-travel debugging that restores task state and re-executes recorded inputs.
- Supports typed lossless log codecs, anytime computation, and clock sync to PTP or custom references.
- Can interoperate with ROS 2 through Zenoh, and includes profile-guided scheduling tools.
