Issue dossier

The maker documents three XIAO ESP32-S3 boards, patch antennas, display, lithium-ion cell, Gerbers, a battery cage, and real build caveats including reversed battery connector polarity, button-footprint mismatch, and fit variation. Reviewed sources do not establish a full final BOM or substitutions, unit inspection, battery cell provenance, charge/protection settings, current or thermal measurements, enclosure safety, RF exposure, emissions/regulatory compliance, ESD/short/reverse protection, test results, or safe assembly/service instructions.

A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
