CarWatch v0.1.0 - a car that answers in the group chat

First release, cut the same day the system proved itself on the road.

What this is: a Raspberry Pi in a Mercedes E 300e that reads the car over OBD, serves a live dashboard through its own Cloudflare tunnel, and lives in a GroupMind room as @eclass - the car answers questions, posts its own readings, and runs a daily deep scan, with no human relaying data.

Proven in-car today (2026-08-24):

• Live telemetry over Bluetooth ELM327: rpm, speed, coolant, hybrid SoC, 12 V, fuel codes, VIN - posted to the room on real events only, never spam
• First in-car deep scan: per-ECU reads, 12 PIDs, VIN, 12.8 s, read-only
• Discovery: continuous Mercedes 0x300-range broadcast frames are audible through the port (senders 0x307/0x328/0x33D) - an undecoded internal telemetry stream, logged as the next project
• Self-update over its own tunnel while parked anywhere with signal
• Honesty hardening: the on-board agent may only quote numbers present in its latest real reading; camera views are declared nonexistent (rule added after the model once invented 7776 rpm)

Docs: docs/data-access.md lists in plain language what data is accessible, what is discovered-but-undecoded, and which doors are closed.

Hardware: any Raspberry Pi class machine + a Bluetooth or USB ELM327. The room protocol is GroupMind (antfarm.world API).
