  "message": "pw_build: Add pw_hermetic_cc_library Bazel rule\n\nAdds `pw_hermetic_cc_library`, a custom Bazel rule for creating\nincrementally-linked hermetic C/C++ static libraries.\n\nAn incrementally-linked hermetic library compiles sources from `srcs`,\ntakes private dependencies from `deps`, performs a relocatable link\n(`ld -r`), and localizes all internal symbols using `objcopy`. Only\nsymbols explicitly listed in `global_symbols` (or `global_symbols_file`)\nremain globally exported, avoiding symbol collisions across dependencies.\n\nFeatures:\n- Supports constraint checks for disallowed `.init_array` / `.fini_array`\n  sections (`allow_init`, `allow_fini`).\n- Supports undefined symbol verification against an allowlist\n  (`undefined_symbols`) via a dedicated pyelftools script\n  (`pw_build/py/pw_build/verify_hermetic_elf.py`).\n\nDerived from:\nhttps://cs.opensource.google/fuchsia/fuchsia/+/main:build/toolchain/hermetic_source_set.gni\n\nTAG\u003dagy\nCONV\u003d888be584-d2e8-42d1-9db3-ff5ef356cbf0\n\nBug: 529790473\nChange-Id: I2bd0b9f895be01fa6322511b5fefe4e0a948a676\nReviewed-on: https://pigweed-review.googlesource.com/c/pigweed/pigweed/+/430932\n",
