# .clang-tidy — C11 static analysis configuration (BLOCKING).
#
# ALL checks enabled. WarningsAsErrors: '*'.
# Check thresholds configured for idiomatic C11 (not C++).
#
# Disabled checks (with reasoning):
#
# C++ idiom checks (not applicable to C11):
#   - bugprone-multi-level-implicit-pointer-conversion: void* is implicit in C
#   - readability-implicit-bool-conversion: if(ptr), if(count) is idiomatic C
#
# LLVM analyzer false positives (no fix available):
#   - DeprecatedOrUnsafeBufferHandling: flags fprintf/snprintf, Annex K not
#     available on Linux/macOS (LLVM #64027)
#   - ArrayBound: taint analysis false positives on buf[fread_result] (LLVM #126884)
#
# Cosmetic checks whitelisted (no memory safety or performance impact):
#   - bugprone-easily-swappable-parameters: internal APIs with descriptive
#     param names; struct wrappers would add churn without safety benefit
#   - concurrency-mt-unsafe: only readdir() remains, which is safe with
#     per-directory-handle usage (each thread owns its DIR*)
#   - bugprone-command-processor: popen() required for git integration;
#     all inputs are validated internal strings, no injection risk
