Issue dossier
A linkable camp-impact record with badge context, severity, evidence confidence, and source notes.
Software claims stay limited to the recovered repository, filesystem README, and release assets.
Evidence
FPGA-related tree with main, tests, and uart_coprocessor projects referenced by the README tooling notes.
Public GreyBadge repository whose GitHub description identifies GreyMecha/Army as the GreyCTF 2025 badge.
Official NUS Greyhats summit page used for event title, Singapore summit context, July 5, 2025 date, and NUS School of Computing COM1 venue.
Release trail with summit_v1/summit_v2 UF2 and filesystem assets, finals firmware assets, and prototype PCB production assets.
RP2350 filesystem README documenting CircuitPython basis, image customization, challenge names, update guidance, and contributor credits.
KiCad project directory with greybadge PCB, RP2350, ECP5 FPGA, TinyFPGA, JLCPCB, library, and production files.
