  "message": "Bound formatted string lengths with `ABSL_ASSUME` across `absl/strings`.\n\nIn hardened builds, constructing an `absl::string_view` checks that its length does not exceed `absl::string_view::max_size()`, emitting a comparison, branch, and trap instruction (`ud2`) whenever the compiler cannot statically upper-bound the runtime length returned by out-of-line formatting routines such as `FastIntToBuffer`, `SixDigitsToBuffer`, and `FastHexToBufferZeroPad16`, or tracked across `FormatSinkImpl` and `IntDigits` scratch buffers. Similarly, `IntegerToString` and `FloatToString` only asserted `size \u003c buf_size` in debug builds, preventing release builds from proving that formatted outputs fit within `std::string` small-string capacity.\n\nAdd `ABSL_ASSUME` bounds on scratch-buffer string lengths across `AlphaNum` (`str_cat.h`), `FormatHex`/`FormatDec`/`IntegerToString`/`FloatToString` (`str_cat.cc`), `substitute_internal::Arg` (`substitute.h`, `substitute.cc`), `SourceLocation` stringification (`stringify_sink.h`, `stringify_sink.cc`), `FormatSinkImpl::Flush` (`str_format/extension.h`), and `IntDigits` (`str_format/arg.cc`). Static ThinLTO release builds eliminate 331 to 593 `ud2` traps and reduce `.text` by an additional 2.5 KB to 5.4 KB per test binary.\n\nPiperOrigin-RevId: 1003911333\n",
