twislaandClaude Opus 5.5 fed065a6f9 M3 step 1: RadioLib and lora probe
The probe finds the SX1262 (TCXO 1.8 V works) and measures the antenna
path: the Cap's PI4IOE5V6408 at 0x43 must drive P0 high, or the receiver
is deaf (-111.9 dBm flat vs -87 to -94 dBm with P0 high). DIO2 makes no
difference to reception. Receive only; the radio is left asleep.

RadioLib 7.8.1 + probe: +23.6 KB flash, +656 B static RAM (release).
