Agent 1 writes to hydrogen-line memory with a live OpenWebRX
/status.json snapshot (software-radio channel evidence).
Agent 2 reads the same location and writes an acknowledgment linked to Agent 1’s key.
Agent 3 verifies integrity and semantic checks; on failure, returns structured
fix_suggestions (env, retry, persistence).
