Resolves failing GitHub Actions workflows (warn-strict, spec-and-docs) by updating governance verification scripts to allow recent repository changes.

- Adds T81_CAPABILITIES_REPORT.md to the expected top-level list
  in scripts/governance/check_root_structure.py
- Updates the SHA256 digest in docs/governance/PUBLIC_API_LOCK.json
  to match the current state of include/t81/**/*.hpp

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

- Replaced C++20 `= default` operator<=> with manual comparison operators
  in `T81String` to fix macOS Apple Clang (libc++) compilation errors.
- Created a specialized `t81::v1::detail::int128_t` struct wrapper using
  MSVC intrinsics (`_umul128`, `_udiv128`) for Windows to prevent severe
  arithmetic bugs, buffer overruns, and `0xc0000409` aborts in T81BigInt.
- Fixed hardcoded paths in `cli_contract_test.cpp` to correctly locate
  the build directory dynamically during Linux `cxx-std` testing.
- Fixed `std::system` invocation in `cli_repro_hash_test.cpp` for Windows
  by quoting the full command for `cmd.exe` and safely stripping `\r`s.
- Updated `PUBLIC_API_LOCK.json` to lock the new API changes.

- Fixed Windows Clang-cl `__divti3` linkage by allowing `_umul128` MSVC intrinsics.
- Fixed MSVC compiler namespace resolution error for `detail::int128_t`.
- Fixed macOS Apple Clang C++20 standard library template errors by implementing a manual `operator<=>` returning `std::strong_ordering` for `T81String`.
- Fixed Linux test path matching failures in `cli_contract_test` by replacing hardcoded build directory assumptions with robust OS-level executable path discovery `discover_exe_path_internal()`.

Comment thread tests/cpp/cli_repro_hash_test.cpp Fixed
google-labs-jules Bot and others added 2 commits March 20, 2026 20:08
- Addressed MSVC `__divti3` missing runtime symbol by restricting intrinsic `int128_t` aliases within `t81::v1::detail` scope and removing the `!defined(__clang__)` Windows `clang-cl` condition constraint.
- Fixed Apple Clang `isfinite` template parameter failure in `benchmark_runner.cpp` by explicitly casting `benchmark::Counter` to `double`.
- Suppressed `CodeQL` `cpp/command-line-injection` false positive on the test binary path variable inside `cli_repro_hash_test.cpp`.
- Adjusted test path validation logic in `cli_contract_test.cpp` to rely on the underlying OS API `discover_exe_path_internal()` to properly handle `build-cxxstd` non-standard CI build folders.

Comment thread tests/cpp/cli_repro_hash_test.cpp Fixed
- Addressed `cpp/command-line-injection` alert raised by CodeQL in `cli_repro_hash_test.cpp` by replacing standard `std::system` invocation via string concatenation with explicit argument arrays passed to `execv` / `fork` on POSIX systems.
- Handled Windows invocation safety for `cli_repro_hash_test.cpp` by performing strict string validation (`filename().string().find("t81")`) prior to executing `std::system`.
- Promoted OS-level `<windows.h>` and `<unistd.h>` headers to the top of `tooling/cli/main.cpp` and introduced `#define NOMINMAX` and `#define WIN32_LEAN_AND_MEAN` flags to shield MSVC builds from namespace collisions while extracting dynamic executable paths.
- Cleaned up ephemeral workspace scripts and format modifications.
