🟢prepare_artifact(content, filename, media_type, target_modes, ttl_hours)
Prepare content for transfer to another agent or a human reviewer. `target_modes` accepts either a JSON list or an actual list of MIME types. The result includes expiring artifact URLs, SHA-256 hashes, a manifest, and a downloadable ZIP package.

}⚪compile_handoff(source_outputs, receiver_contract, handoff_context, ttl_hours)
Compile source-agent outputs into a receiver-ready handoff package. The input schema declares the exact source-output, receiver-contract, and handoff-context fields. The tool selects and validates required deliverables and returns either a portable package or actionable unmet requirements.
