Sure thing, let’s keep it lean. How about a JSON schema that looks like this: ``` { "ecuId": "string", // unique identifier for the ECU "timestamp": "ISO8601", // UTC time of the event "eventType": "string", // e.g., “fault”, “status”, “update” "severity": "int", // 0–5 scale, 0 = info, 5 = critical "payload": { // event‑specific data /* key/value pairs, e.g. */ "errorCode": "0x1234", "temperature": 87 }, "source": "string" // optional, e.g., “sensor”, “control‑unit” } ``` You can serialise each record to a line in a log file or push it straight into a message bus. If you need to compress, just base‑64 the payload or keep it as a flat string. How does that feel for the initial draft?
