- envelope: 7 fixed keys + conditional dataArea, no data key; int
type/snno, seconds timestamp, data setter auto len/crc (CRC32 upper);
SequenceNumber 1..9999 (increaseSN)
- crypto: encrypt is plaintext-header-first a||transform(b), key radix 32
at both tryParse sites; decrypt_data ports decryptData (dual-0x58
markers, s+'}' equipNo probe, s+','+T return); decrypt_request kept
for the device-side known-header split
- socket: raw send (no length prefix), accumulate-and-try receive
- battery: queryAPowerData shape (data={'update':2}), radix default 32,
--probe prints exact TX/RX bytes per variant; device_local.send_probe
- docs: RE_DART_FINDINGS ss3/5/8 + open items, BATTERY_POC host recipe
- tests: 19 new protocol tests, suite 44/44 green
