Detailed Description

Decoded per-unit payload (the 96-byte record body).

The in-memory form of the serialised body. touch_cal carries the exact 36-byte blob produced by ra8_touch_cal_save – this record is that blob's durable home.

Note: device_key_id is an IDENTIFIER ONLY, never key material: there is no working key-wrapping engine on this silicon and the debug port is open (#244), so a private key here would be plaintext to anyone with physical access. Adding real key storage later is a schema_version bump, not a redesign.

Invariant: panel_vcom_mv is a VCOM magnitude in millivolts; VCOM is negative and the sign is implicit (2300 => -2.30 V), matching the IT8951 0x0039 command encoding.
