  "message": "Intern flag source filenames at registration into a 16-bit file ID.\n\nEvery `absl::Flag` in writable data carries an 8-byte source filename pointer and a dynamic relocation entry, even though binaries define several times more flags than flag-defining source files.\n\nPass the filename string literal from the static registrar into `absl::flags_internal::FlagImpl` at startup, recording each translation unit\u0027s filename in a process-wide pointer vector and storing its 1-based 16-bit ID in existing padding. Because all flags in a translation unit register consecutively from one static initializer and share the same `__FILE__` string literal, comparing pointers against only the last vector entry deduplicates per-file filenames in constant time without a hash table. Dropping the filename pointer shrinks `FlagImpl` from 64 bytes to 56 bytes, reduces scalar flags from 72 bytes to 64 bytes, and removes one dynamic relocation per flag.\n\nPiperOrigin-RevId: 1006216268\n",
