.clang-tidy

---
# Static analysis for the C daemon and unit tests.
#
# Curated check set — every enabled family must catch real bugs, not
# style preferences. The pattern follows the schnelle-umlaute checks
# but trimmed for C (no -modernize-*, no -cppcoreguidelines-*).
#
# bugprone-*           — concrete bug patterns (suspicious-string-compare,
#                         signed-char-misuse, integer-division, branch-clone)
# clang-analyzer-*     — LLVM's static analyzer (null deref, leaks, UAF)
# portability-*        — platform-portability issues
# performance-*        — perf anti-patterns
# readability-non-const-parameter — caller may pass const; fix the API
# misc-include-cleaner — unused / missing includes
#
# Explicit -checks disable the noisy ones that fire on patterns we
# intentionally use (sscanf parsing, fixed-size buffers, magic numbers
# baked into the spnav protocol).
