Every accessor is a header-only constexpr function so the __DATE__ / __TIME__ macros and the MNE_GIT_HASH_* defines (injected by CMake at configure time) are evaluated in the translation unit that invokes them. The values are picked up by utils_global.cpp exactly once so every mne-cpp binary reports a single, stable build identifier in its About dialog, CLI --version banner, and crash logs.

When git metadata is unavailable (source tarball builds, shallow CI checkouts) the hash accessors return a constant sentinel string instead of failing the build.
