## F4 Code Quality Review (2026-06-15)

- All 10 header guards use #ifndef NAME_H_ convention — matches project AGENTS.md
- All 44 declared functions have implementations — 100% coverage
- Zero stdint types in embedded code; Linux test uses stdint correctly
- Zero dead loops (while(1);) in non-main paths
- Zero hardcoded paths in embedded code
- 1 TODO: gmsp_dispatch.c:598 — chip SN placeholder (0xFFu fill), legitimate stub
- No FIXME/HACK/XXX found
