## What changed
- Remove automatic BuildBuddy configuration and credential forwarding from Bazel CI, release, SDK, and voice builds. Strip remote execution CI configs in the shared wrapper while retaining explicit remote configurations for local use.
- Use native Windows host tools and audio dependencies for Windows Bazel actions, forwarding the required toolchain and environment settings.
- Initialize message-board MCP servers through a per-session `OnceCell` so server startup does not hold the shared registry lock across an await.
- Expose the message-board test helper to the core Bazel package and update the runtime-auth test call for the `reauth` argument.

## What changed
- Build native voice SDK and runtime artifacts with Bazel for Linux GNU, macOS, and Windows on x64 and ARM64, then configure Cargo jobs to consume them. Keep musl builds in a separate job without these inputs.
- Validate artifact receipts against the target, source commit, and source manifest; verify SDK file hashes and relocate pkg-config metadata. Package the runtime and plugins with nextest archives and restore `CODEX_TEST_VOICE_RUNTIME` when running shards.
- Prepare native Windows voice tools for argument-comment linting and install ARM64 DotSlash on Windows ARM64. Reduce archive disk usage, bound Linux ARM64 build concurrency, and correct the JUnit artifact path.
- Recognize TLS errors wrapped directly in `io::Error`. Make TLS fallback fixtures select the native backend explicitly, allow the MCP test server's non-loopback address, and isolate skill-root tests from ancestor Git markers. Install `git` in remote test containers and filter MCP discovery assertions to POST requests.
## Testing
Add tests for relocated voice inputs, Windows ARM64 import libraries with host-native pkgconf, and rejection of mismatched receipts or corrupt SDK files. Extend untrusted-certificate coverage to an explicitly selected rustls backend.

## Why
A rerun of the Windows Bazel clippy job after
[#19161](https://github.com/openai/codex/pull/19161) had exactly the
cache behavior we wanted in BuildBuddy: zero action-cache misses. Even
so, the GitHub job still took a little over five minutes.
The problem was that the job was paying for two separate Bazel startup
paths:
1. a `bazel query` to discover extra lint targets
2. the real `bazel build --config=clippy ...` invocation
On Windows, that query was bypassing the CI Bazel wrapper, so it did not
reuse the same `--output_user_root`, CI config, or remote-cache setup as
the real build. In practice that meant the rerun could still cold-start
a separate Bazel server before the actual clippy build even began.
## What
- add `.github/scripts/run-bazel-query-ci.sh` to run CI-side Bazel
queries with the same startup and cache-related flags as the main Bazel
command
- switch `scripts/list-bazel-clippy-targets.sh` to use that helper for
manual `rust_test` target discovery
- switch `tools/argument-comment-lint/list-bazel-targets.sh` to use the
same helper
- simplify `.github/scripts/run-argument-comment-lint-bazel.sh` so its
Windows-only query path also goes through the shared helper
This keeps the target-discovery queries aligned with the later
build/test invocation instead of treating them as a separate cold Bazel
session.
## Verification
- `bash -n .github/scripts/run-bazel-query-ci.sh`
- `bash -n scripts/list-bazel-clippy-targets.sh`
- `bash -n tools/argument-comment-lint/list-bazel-targets.sh`
- `bash -n .github/scripts/run-argument-comment-lint-bazel.sh`
- mocked a Windows invocation of `run-bazel-query-ci.sh` and verified it
forwards `--output_user_root`, `--config=ci-windows`, the BuildBuddy
auth header, and the repository cache flags
## Docs
No documentation updates are needed.
## Why
Follow-up to #16106.
`argument-comment-lint` already runs as a native Bazel aspect on Linux
and macOS, but Windows is still the long pole in `rust-ci`. To move
Windows onto the same native Bazel lane, the toolchain split has to let
exec-side helper binaries build in an MSVC environment while still
linting repo crates as `windows-gnullvm`.
Pushing the Windows lane onto the native Bazel path exposed a second
round of Windows-only issues in the mixed exec-toolchain plumbing after
the initial wrapper/target fixes landed.
## What Changed
- keep the Windows lint lanes on the native Bazel/aspect path in
`rust-ci.yml` and `rust-ci-full.yml`
- add a dedicated `local_windows_msvc` platform for exec-side helper
binaries while keeping `local_windows` as the `windows-gnullvm` target
platform
- patch `rules_rust` so `repository_set(...)` preserves explicit
exec-platform constraints for the generated toolchains, keep the
Windows-specific bootstrap/direct-link fixes needed for the nightly lint
driver, and expose exec-side `rustc-dev` `.rlib`s to the MSVC sysroot
- register the custom Windows nightly toolchain set with MSVC exec
constraints while still exposing both `x86_64-pc-windows-msvc` and
`x86_64-pc-windows-gnullvm` targets
- enable `dev_components` on the custom Windows nightly repository set
so the MSVC exec helper toolchain actually downloads the
compiler-internal crates that `clippy_utils` needs
- teach `run-argument-comment-lint-bazel.sh` to enumerate concrete
Windows Rust rules, normalize the resulting labels, and skip explicitly
requested incompatible targets instead of failing before the lint run
starts
- patch `rules_rust` build-script env propagation so exec-side
`windows-msvc` helper crates drop forwarded MinGW include and linker
search paths as whole flag/path pairs instead of emitting malformed
`CFLAGS`, `CXXFLAGS`, and `LDFLAGS`
- export the Windows VS/MSVC SDK environment in `setup-bazel-ci` and
pass the relevant variables through `run-bazel-ci.sh` via `--action_env`
/ `--host_action_env` so Bazel build scripts can see the MSVC and UCRT
headers on native Windows runs
- add inline comments to the Windows `setup-bazel-ci` MSVC environment
export step so it is easier to audit how `vswhere`, `VsDevCmd.bat`, and
the filtered `GITHUB_ENV` export fit together
- patch `aws-lc-sys` to skip its standalone `memcmp` probe under Bazel
`windows-msvc` build-script environments, which avoids a Windows-native
toolchain mismatch that blocked the lint lane before it reached the
aspect execution
- patch `aws-lc-sys` to prefer its bundled `prebuilt-nasm` objects for
Bazel `windows-msvc` build-script runs, which avoids missing
`generated-src/win-x86_64/*.asm` runfiles in the exec-side helper
toolchain
- annotate the Linux test-only callsites in `codex-rs/linux-sandbox` and
`codex-rs/core` that the wider native lint coverage surfaced
## Patches
This PR introduces a large patch stack because the Windows Bazel lint
lane currently depends on behavior that upstream dependencies do not
provide out of the box in the mixed `windows-gnullvm` target /
`windows-msvc` exec-toolchain setup.
- Most of the `rules_rust` patches look like upstream candidates rather
than OpenAI-only policy. Preserving explicit exec-platform constraints,
forwarding the right MSVC/UCRT environment into exec-side build scripts,
exposing exec-side `rustc-dev` artifacts, and keeping the Windows
bootstrap/linker behavior coherent all look like fixes to the Bazel/Rust
integration layer itself.
- The two `aws-lc-sys` patches are more tactical. They special-case
Bazel `windows-msvc` build-script environments to avoid a `memcmp` probe
mismatch and missing NASM runfiles. Those may be harder to upstream
as-is because they rely on Bazel-specific detection instead of a general
Cargo/build-script contract.
- Short term, carrying these patches in-tree is reasonable because they
unblock a real CI lane and are still narrow enough to audit. Long term,
the goal should not be to keep growing a permanent local fork of either
dependency.
- My current expectation is that the `rules_rust` patches are less
controversial and should be broken out into focused upstream proposals,
while the `aws-lc-sys` patches are more likely to be temporary escape
hatches unless that crate wants a more general hook for hermetic build
systems.
Suggested follow-up plan:
1. Split the `rules_rust` deltas into upstream-sized PRs or issues with
minimized repros.
2. Revisit the `aws-lc-sys` patches during the next dependency bump and
see whether they can be replaced by an upstream fix, a crate upgrade, or
a cleaner opt-in mechanism.
3. Treat each dependency update as a chance to delete patches one by one
so the local patch set only contains still-needed deltas.
