eaf12beacf Codex/windows bazel rust test coverage no rs (#16528)
# Why this PR exists

This PR is trying to fix a coverage gap in the Windows Bazel Rust test
lane.

Before this change, the Windows `bazel test //...` job was nominally
part of PR CI, but a non-trivial set of `//codex-rs/...` Rust test
targets did not actually contribute test signal on Windows. In
particular, targets such as `//codex-rs/core:core-unit-tests`,
`//codex-rs/core:core-all-test`, and `//codex-rs/login:login-unit-tests`
were incompatible during Bazel analysis on the Windows gnullvm platform,
so they never reached test execution there. That is why the
Cargo-powered Windows CI job could surface Windows-only failures that
the Bazel-powered job did not report: Cargo was executing those tests,
while Bazel was silently dropping them from the runnable target set.

The main goal of this PR is to make the Windows Bazel test lane execute
those Rust test targets instead of skipping them during analysis, while
still preserving `windows-gnullvm` as the target configuration for the
code under test. In other words: use an MSVC host/exec toolchain where
Bazel helper binaries and build scripts need it, but continue compiling
the actual crate targets with the Windows gnullvm cfgs that our current
Bazel matrix is supposed to exercise.

# Important scope note

This branch intentionally removes the non-resource-loading `.rs` test
and production-code changes from the earlier
`codex/windows-bazel-rust-test-coverage` branch. The only Rust source
changes kept here are runfiles/resource-loading fixes in TUI tests:

- `codex-rs/tui/src/chatwidget/tests.rs`
- `codex-rs/tui/tests/manager_dependency_regression.rs`

That is deliberate. Since the corresponding tests already pass under
Cargo, this PR is meant to test whether Bazel infrastructure/toolchain
fixes alone are enough to get a healthy Windows Bazel test signal,
without changing test behavior for Windows timing, shell output, or
SQLite file-locking.

# How this PR changes the Windows Bazel setup

## 1. Split Windows host/exec and target concerns in the Bazel test lane

The core change is that the Windows Bazel test job now opts into an MSVC
host platform for Bazel execution-time tools, but only for `bazel test`,
not for the Bazel clippy build.

Files:

- `.github/workflows/bazel.yml`
- `.github/scripts/run-bazel-ci.sh`
- `MODULE.bazel`

What changed:

- `run-bazel-ci.sh` now accepts `--windows-msvc-host-platform`.
- When that flag is present on Windows, the wrapper appends
`--host_platform=//:local_windows_msvc` unless the caller already
provided an explicit `--host_platform`.
- `bazel.yml` passes that wrapper flag only for the Windows `bazel test
//...` job.
- The Bazel clippy job intentionally does **not** pass that flag, so
clippy stays on the default Windows gnullvm host/exec path and continues
linting against the target cfgs we care about.
- `run-bazel-ci.sh` also now forwards `CODEX_JS_REPL_NODE_PATH` on
Windows and normalizes the `node` executable path with `cygpath -w`, so
tests that need Node resolve the runner's Node installation correctly
under the Windows Bazel test environment.

Why this helps:

- The original incompatibility chain was mostly on the **exec/tool**
side of the graph, not in the Rust test code itself. Moving host tools
to MSVC lets Bazel resolve helper binaries and generators that were not
viable on the gnullvm exec platform.
- Keeping the target platform on gnullvm preserves cfg coverage for the
crates under test, which is important because some Windows behavior
differs between `msvc` and `gnullvm`.

## 2. Teach the repo's Bazel Rust macro about Windows link flags and
integration-test knobs

Files:

- `defs.bzl`
- `codex-rs/core/BUILD.bazel`
- `codex-rs/otel/BUILD.bazel`
- `codex-rs/tui/BUILD.bazel`

What changed:

- Replaced the old gnullvm-only linker flag block with
`WINDOWS_RUSTC_LINK_FLAGS`, which now handles both Windows ABIs:
  - gnullvm gets `-C link-arg=-Wl,--stack,8388608`
- MSVC gets `-C link-arg=/STACK:8388608`, `-C
link-arg=/NODEFAULTLIB:libucrt.lib`, and `-C link-arg=ucrt.lib`
- Threaded those Windows link flags into generated `rust_binary`,
unit-test binaries, and integration-test binaries.
- Extended `codex_rust_crate(...)` with:
  - `integration_test_args`
  - `integration_test_timeout`
- Used those new knobs to:
- mark `//codex-rs/core:core-all-test` as a long-running integration
test
  - serialize `//codex-rs/otel:otel-all-test` with `--test-threads=1`
- Added `src/**/*.rs` to `codex-rs/tui` test runfiles, because one
regression test scans source files at runtime and Bazel does not expose
source-tree directories unless they are declared as data.

Why this helps:

- Once host-side MSVC tools are available, we still need the generated
Rust test binaries to link correctly on Windows. The MSVC-side
stack/UCRT flags make those binaries behave more like their Cargo-built
equivalents.
- The integration-test macro knobs avoid hardcoding one-off test
behavior in ad hoc BUILD rules and make the generated test targets more
expressive where Bazel and Cargo have different runtime defaults.

## 3. Patch `rules_rs` / `rules_rust` so Windows MSVC exec-side Rust and
build scripts are actually usable

Files:

- `MODULE.bazel`
- `patches/rules_rs_windows_exec_linker.patch`
- `patches/rules_rust_windows_bootstrap_process_wrapper_linker.patch`
- `patches/rules_rust_windows_build_script_runner_paths.patch`
- `patches/rules_rust_windows_exec_msvc_build_script_env.patch`
- `patches/rules_rust_windows_msvc_direct_link_args.patch`
- `patches/rules_rust_windows_process_wrapper_skip_temp_outputs.patch`
- `patches/BUILD.bazel`

What these patches do:

- `rules_rs_windows_exec_linker.patch`
- Adds a `rust-lld` filegroup for Windows Rust toolchain repos,
symlinked to `lld-link.exe` from `PATH`.
  - Marks Windows toolchains as using a direct linker driver.
  - Supplies Windows stdlib link flags for both gnullvm and MSVC.
- `rules_rust_windows_bootstrap_process_wrapper_linker.patch`
- For Windows MSVC Rust targets, prefers the Rust toolchain linker over
an inherited C++ linker path like `clang++`.
- This specifically avoids the broken mixed-mode command line where
rustc emits MSVC-style `/NOLOGO` / `/LIBPATH:` / `/OUT:` arguments but
Bazel still invokes `clang++.exe`.
- `rules_rust_windows_build_script_runner_paths.patch`
- Normalizes forward-slash execroot-relative paths into Windows path
separators before joining them on Windows.
- Uses short Windows paths for `RUSTC`, `OUT_DIR`, and the build-script
working directory to avoid path-length and quoting issues in third-party
build scripts.
- Exposes `RULES_RUST_BAZEL_BUILD_SCRIPT_RUNNER=1` to build scripts so
crate-local patches can detect "this is running under Bazel's
build-script runner".
- Fixes the Windows runfiles cleanup filter so generated files with
retained suffixes are actually retained.
- `rules_rust_windows_exec_msvc_build_script_env.patch`
- For exec-side Windows MSVC build scripts, stops force-injecting
Bazel's `CC`, `CXX`, `LD`, `CFLAGS`, and `CXXFLAGS` when that would send
GNU-flavored tool paths/flags into MSVC-oriented Cargo build scripts.
- Rewrites or strips GNU-only `--sysroot`, MinGW include/library paths,
stack-protector, and `_FORTIFY_SOURCE` flags on the MSVC exec path.
- The practical effect is that build scripts can fall back to the Visual
Studio toolchain environment already exported by CI instead of crashing
inside Bazel's hermetic `clang.exe` setup.
- `rules_rust_windows_msvc_direct_link_args.patch`
- When using a direct linker on Windows, stops forwarding GNU driver
flags such as `-L...` and `--sysroot=...` that `lld-link.exe` does not
understand.
- Passes non-`.lib` native artifacts as explicit `-Clink-arg=<path>`
entries when needed.
- Filters C++ runtime libraries to `.lib` artifacts on the Windows
direct-driver path.
- `rules_rust_windows_process_wrapper_skip_temp_outputs.patch`
- Excludes transient `*.tmp*` and `*.rcgu.o` files from process-wrapper
dependency search-path consolidation, so unstable compiler outputs do
not get treated as real link search-path inputs.

Why this helps:

- The host-platform split alone was not enough. Once Bazel started
analyzing/running previously incompatible Rust tests on Windows, the
next failures were in toolchain plumbing:
- MSVC-targeted Rust tests were being linked through `clang++` with
MSVC-style arguments.
- Cargo build scripts running under Bazel's Windows MSVC exec platform
were handed Unix/GNU-flavored path and flag shapes.
- Some generated paths were too long or had path-separator forms that
third-party Windows build scripts did not tolerate.
- These patches make that mixed Bazel/Cargo/Rust/MSVC path workable
enough for the test lane to actually build and run the affected crates.

## 4. Patch third-party crate build scripts that were not robust under
Bazel's Windows MSVC build-script path

Files:

- `MODULE.bazel`
- `patches/aws-lc-sys_windows_msvc_prebuilt_nasm.patch`
- `patches/ring_windows_msvc_include_dirs.patch`
- `patches/zstd-sys_windows_msvc_include_dirs.patch`

What changed:

- `aws-lc-sys`
- Detects Bazel's Windows MSVC build-script runner via
`RULES_RUST_BAZEL_BUILD_SCRIPT_RUNNER` or a `bazel-out` manifest-dir
path.
- Uses `clang-cl` for Bazel Windows MSVC builds when no explicit
`CC`/`CXX` is set.
- Allows prebuilt NASM on the Bazel Windows MSVC path even when `nasm`
is not available directly in the runner environment.
- Avoids canonicalizing `CARGO_MANIFEST_DIR` in the Bazel Windows MSVC
case, because that path may point into Bazel output/runfiles state where
preserving the given path is more reliable than forcing a local
filesystem canonicalization.
- `ring`
- Under the Bazel Windows MSVC build-script runner, copies the
pregenerated source tree into `OUT_DIR` and uses that as the
generated-source root.
- Adds include paths needed by MSVC compilation for
Fiat/curve25519/P-256 generated headers.
- Rewrites a few relative includes in C sources so the added include
directories are sufficient.
- `zstd-sys`
- Adds MSVC-only include directories for `compress`, `decompress`, and
feature-gated dictionary/legacy/seekable sources.
- Skips `-fvisibility=hidden` on MSVC targets, where that
GCC/Clang-style flag is not the right mechanism.

Why this helps:

- After the `rules_rust` plumbing started running build scripts on the
Windows MSVC exec path, some third-party crates still failed for
crate-local reasons: wrong compiler choice, missing include directories,
build-script assumptions about manifest paths, or Unix-only C compiler
flags.
- These crate patches address those crate-local assumptions so the
larger toolchain change can actually reach first-party Rust test
execution.

## 5. Keep the only `.rs` test changes to Bazel/Cargo runfiles parity

Files:

- `codex-rs/tui/src/chatwidget/tests.rs`
- `codex-rs/tui/tests/manager_dependency_regression.rs`

What changed:

- Instead of asking `find_resource!` for a directory runfile like
`src/chatwidget/snapshots` or `src`, these tests now resolve one known
file runfile first and then walk to its parent directory.

Why this helps:

- Bazel runfiles are more reliable for explicitly declared files than
for source-tree directories that happen to exist in a Cargo checkout.
- This keeps the tests working under both Cargo and Bazel without
changing their actual assertions.

# What we tried before landing on this shape, and why those attempts did
not work

## Attempt 1: Force `--host_platform=//:local_windows_msvc` for all
Windows Bazel jobs

This did make the previously incompatible test targets show up during
analysis, but it also pushed the Bazel clippy job and some unrelated
build actions onto the MSVC exec path.

Why that was bad:

- Windows clippy started running third-party Cargo build scripts with
Bazel's MSVC exec settings and crashed in crates such as `tree-sitter`
and `libsqlite3-sys`.
- That was a regression in a job that was previously giving useful
gnullvm-targeted lint signal.

What this PR does instead:

- The wrapper flag is opt-in, and `bazel.yml` uses it only for the
Windows `bazel test` lane.
- The clippy lane stays on the default Windows gnullvm host/exec
configuration.

## Attempt 2: Broaden the `rules_rust` linker override to all Windows
Rust actions

This fixed the MSVC test-lane failure where normal `rust_test` targets
were linked through `clang++` with MSVC-style arguments, but it broke
the default gnullvm path.

Why that was bad:

-
`@@rules_rs++rules_rust+rules_rust//util/process_wrapper:process_wrapper`
on the gnullvm exec platform started linking with `lld-link.exe` and
then failed to resolve MinGW-style libraries such as `-lkernel32`,
`-luser32`, and `-lmingw32`.

What this PR does instead:

- The linker override is restricted to Windows MSVC targets only.
- The gnullvm path keeps its original linker behavior, while MSVC uses
the direct Windows linker.

## Attempt 3: Keep everything on pure Windows gnullvm and patch the V8 /
Python incompatibility chain instead

This would have preserved a single Windows ABI everywhere, but it is a
much larger project than this PR.

Why that was not the practical first step:

- The original incompatibility chain ran through exec-side generators
and helper tools, not only through crate code.
- `third_party/v8` is already special-cased on Windows gnullvm because
`rusty_v8` only publishes Windows prebuilts under MSVC names.
- Fixing that path likely means deeper changes in
V8/rules_python/rules_rust toolchain resolution and generator execution,
not just one local CI flag.

What this PR does instead:

- Keep gnullvm for the target cfgs we want to exercise.
- Move only the Windows test lane's host/exec platform to MSVC, then
patch the build-script/linker boundary enough for that split
configuration to work.

## Attempt 4: Validate compatibility with `bazel test --nobuild ...`

This turned out to be a misleading local validation command.

Why:

- `bazel test --nobuild ...` can successfully analyze targets and then
still exit 1 with "Couldn't start the build. Unable to run tests"
because there are no runnable test actions after `--nobuild`.

Better local check:

```powershell
bazel build --nobuild --keep_going --host_platform=//:local_windows_msvc //codex-rs/login:login-unit-tests //codex-rs/core:core-unit-tests //codex-rs/core:core-all-test
```

# Which patches probably deserve upstream follow-up

My rough take is that the `rules_rs` / `rules_rust` patches are the
highest-value upstream candidates, because they are fixing generic
Windows host/exec + MSVC direct-linker behavior rather than
Codex-specific test logic.

Strong upstream candidates:

- `patches/rules_rs_windows_exec_linker.patch`
- `patches/rules_rust_windows_bootstrap_process_wrapper_linker.patch`
- `patches/rules_rust_windows_build_script_runner_paths.patch`
- `patches/rules_rust_windows_exec_msvc_build_script_env.patch`
- `patches/rules_rust_windows_msvc_direct_link_args.patch`
- `patches/rules_rust_windows_process_wrapper_skip_temp_outputs.patch`

Why these seem upstreamable:

- They address general-purpose problems in the Windows MSVC exec path:
  - missing direct-linker exposure for Rust toolchains
  - wrong linker selection when rustc emits MSVC-style args
- Windows path normalization/short-path issues in the build-script
runner
  - forwarding GNU-flavored CC/link flags into MSVC Cargo build scripts
  - unstable temp outputs polluting process-wrapper search-path state

Potentially upstreamable crate patches, but likely with more care:

- `patches/zstd-sys_windows_msvc_include_dirs.patch`
- `patches/ring_windows_msvc_include_dirs.patch`
- `patches/aws-lc-sys_windows_msvc_prebuilt_nasm.patch`

Notes on those:

- The `zstd-sys` and `ring` include-path fixes look fairly generic for
MSVC/Bazel build-script environments and may be straightforward to
propose upstream after we confirm CI stability.
- The `aws-lc-sys` patch is useful, but it includes a Bazel-specific
environment probe and CI-specific compiler fallback behavior. That
probably needs a cleaner upstream-facing shape before sending it out, so
upstream maintainers are not forced to adopt Codex's exact CI
assumptions.

Probably not worth upstreaming as-is:

- The repo-local Starlark/test target changes in `defs.bzl`,
`codex-rs/*/BUILD.bazel`, and `.github/scripts/run-bazel-ci.sh` are
mostly Codex-specific policy and CI wiring, not generic rules changes.

# Validation notes for reviewers

On this branch, I ran the following local checks after dropping the
non-resource-loading Rust edits:

```powershell
cargo test -p codex-tui
just --shell 'C:\Program Files\Git\bin\bash.exe' --shell-arg -lc -- fix -p codex-tui
python .\tools\argument-comment-lint\run-prebuilt-linter.py -p codex-tui
just --shell 'C:\Program Files\Git\bin\bash.exe' --shell-arg -lc fmt
```

One local caveat:

- `just argument-comment-lint` still fails on this Windows machine for
an unrelated Bazel toolchain-resolution issue in
`//codex-rs/exec:exec-all-test`, so I used the direct prebuilt linter
for `codex-tui` as the local fallback.

# Expected reviewer takeaway

If this PR goes green, the important conclusion is that the Windows
Bazel test coverage gap was primarily a Bazel host/exec toolchain
problem, not a need to make the Rust tests themselves Windows-specific.
That would be a strong signal that the deleted non-resource-loading Rust
test edits from the earlier branch should stay out, and that future work
should focus on upstreaming the generic `rules_rs` / `rules_rust`
Windows fixes and reducing the crate-local patch surface.

6fff9955f1 extract models manager and related ownership from core (#16508)
## Summary
- split `models-manager` out of `core` and add `ModelsManagerConfig`
plus `Config::to_models_manager_config()` so model metadata paths stop
depending on `core::Config`
- move login-owned/auth-owned code out of `core` into `codex-login`,
move model provider config into `codex-model-provider-info`, move API
bridge mapping into `codex-api`, move protocol-owned types/impls into
`codex-protocol`, and move response debug helpers into a dedicated
`response-debug-context` crate
- move feedback tag emission into `codex-feedback`, relocate tests to
the crates that now own the code, and keep broad temporary re-exports so
this PR avoids a giant import-only rewrite

## Major moves and decisions
- created `codex-models-manager` as the owner for model
cache/catalog/config/model info logic, including the new
`ModelsManagerConfig` struct
- created `codex-model-provider-info` as the owner for provider config
parsing/defaults and kept temporary `codex-login`/`codex-core`
re-exports for old import paths
- moved `api_bridge` error mapping + `CoreAuthProvider` into
`codex-api`, while `codex-login::api_bridge` temporarily re-exports
those symbols and keeps the `auth_provider_from_auth` wrapper
- moved `auth_env_telemetry` and `provider_auth` ownership to
`codex-login`
- moved `CodexErr` ownership to `codex-protocol::error`, plus
`StreamOutput`, `bytes_to_string_smart`, and network policy helpers to
protocol-owned modules
- created `codex-response-debug-context` for
`extract_response_debug_context`, `telemetry_transport_error_message`,
and related response-debug plumbing instead of leaving that behavior in
`core`
- moved `FeedbackRequestTags`, `emit_feedback_request_tags`, and
`emit_feedback_request_tags_with_auth_env` to `codex-feedback`
- deferred removal of temporary re-exports and the mechanical import
rewrites to a stacked follow-up PR so this PR stays reviewable

## Test moves
- moved auth refresh coverage from `core/tests/suite/auth_refresh.rs` to
`login/tests/suite/auth_refresh.rs`
- moved text encoding coverage from
`core/tests/suite/text_encoding_fix.rs` to
`protocol/src/exec_output_tests.rs`
- moved model info override coverage from
`core/tests/suite/model_info_overrides.rs` to
`models-manager/src/model_info_overrides_tests.rs`

7ba1fccfc1 fix(ci): restore guardian coverage and bazel unit tests (#13912)
## Summary
- restore the guardian review request snapshot test and its tracked
snapshot after it was dropped from `main`
- make Bazel Rust unit-test wrappers resolve runfiles correctly on
manifest-only platforms like macOS and point Insta at the real workspace
root
- harden the shell-escalation socket-closure assertion so the musl Bazel
test no longer depends on fd reuse behavior

## Verification
- cargo test -p codex-core
guardian_review_request_layout_matches_model_visible_request_snapshot
- cargo test -p codex-shell-escalation
- bazel test //codex-rs/exec:exec-unit-tests
//codex-rs/shell-escalation:shell-escalation-unit-tests

Supersedes #13894.

42e22f3bde Add feature-gated freeform js_repl core runtime (#10674)
## Summary

This PR adds an **experimental, feature-gated `js_repl` core runtime**
so models can execute JavaScript in a persistent REPL context across
tool calls.

The implementation integrates with existing feature gating, tool
registration, prompt composition, config/schema docs, and tests.

## What changed

- Added new experimental feature flag: `features.js_repl`.
- Added freeform `js_repl` tool and companion `js_repl_reset` tool.
- Gated tool availability behind `Feature::JsRepl`.
- Added conditional prompt-section injection for JS REPL instructions
via marker-based prompt processing.
- Implemented JS REPL handlers, including freeform parsing and pragma
support (timeout/reset controls).
- Added runtime resolution order for Node:
  1. `CODEX_JS_REPL_NODE_PATH`
  2. `js_repl_node_path` in config
  3. `PATH`
- Added JS runtime assets/version files and updated docs/schema.

## Why

This enables richer agent workflows that require incremental JavaScript
execution with preserved state, while keeping rollout safe behind an
explicit feature flag.

## Testing

Coverage includes:

- Feature-flag gating behavior for tool exposure.
- Freeform parser/pragma handling edge cases.
- Runtime behavior (state persistence across calls and top-level `await`
support).

## Usage

```toml
[features]
js_repl = true
```

Optional runtime override:

- `CODEX_JS_REPL_NODE_PATH`, or
- `js_repl_node_path` in config.

476c1a7160 Remove test-support feature from codex-core and replace it with explicit test toggles (#11405)
## Why

`codex-core` was being built in multiple feature-resolved permutations
because test-only behavior was modeled as crate features. For a large
crate, those permutations increase compile cost and reduce cache reuse.

## Net Change

- Removed the `test-support` crate feature and related feature wiring so
`codex-core` no longer needs separate feature shapes for test consumers.
- Standardized cross-crate test-only access behind
`codex_core::test_support`.
- External test code now imports helpers from
`codex_core::test_support`.
- Underlying implementation hooks are kept internal (`pub(crate)`)
instead of broadly public.

## Outcome

- Fewer `codex-core` build permutations.
- Better incremental cache reuse across test targets.
- No intended production behavior change.

b68a84ee8e Remove deterministic_process_ids feature to avoid duplicate codex-core builds (#11393)
## Why

`codex-core` enabled `deterministic_process_ids` through a self
dev-dependency.
That forced a second feature-resolved build of the same crate, which
increased
compile time and test latency.

## What Changed

- Removed the `deterministic_process_ids` feature from
`codex-rs/core/Cargo.toml`.
- Removed the self dev-dependency on `codex-core` that enabled that
feature.
- Removed the Bazel `deterministic_process_ids` crate feature for
`codex-core`.
- Added a test-only `AtomicBool` override in unified exec process-id
allocation.
- Added a test-support setter for that override and re-exported it from
`codex-core`.
- Enabled deterministic process IDs in integration tests via
`core_test_support` ctor.

## Behavior

- Production behavior remains random process IDs.
- Unit tests remain deterministic via `cfg(test)`.
- Integration tests remain deterministic via explicit test-support
initialization.

## Validation

- `just fmt`
- `cargo test -p codex-core unified_exec::`
- `cargo test -p codex-core --test all unified_exec -- --test-threads=1`
- `cargo tree -p codex-core -e features` (verified the removed feature
path)

Behavior:
1. New models from models endpoint gets added
2. Shared models get replaced by remote ones
3. Existing models in `models.json` but not `/models` are kept

40e2405998 add generated jsonschema for config.toml (#8956)
### What
Add JSON Schema generation for `config.toml`, with checked‑in
`docs/config.schema.json`. We can move the schema elsewhere if preferred
(and host it if there's demand).

Add fixture test to prevent drift and `just write-config-schema` to
regenerate on schema changes.

Generate MCP config schema from `RawMcpServerConfig` instead of
`McpServerConfig` because that is the runtime type used for
deserialization.

Populate feature flag values into generated schema so they can be
autocompleted.

### Tests
Added tests + regenerate script to prevent drift. Tested autocompletions
using generated jsonschema locally with Even Better TOML.

cf515142b0 fix: include AGENTS.md as repo root marker for integration tests (#9010)
As explained in `codex-rs/core/BUILD.bazel`, including the repo's own
`AGENTS.md` is a hack to get some tests passing. We should fix this
properly, but I wanted to put stake in the ground ASAP to get `just
bazel-remote-test` working and then add a job to `bazel.yml` to ensure
it keeps working.

2a06d64bc9 feat: add support for building with Bazel (#8875)
This PR configures Codex CLI so it can be built with
[Bazel](https://bazel.build) in addition to Cargo. The `.bazelrc`
includes configuration so that remote builds can be done using
[BuildBuddy](https://www.buildbuddy.io).

If you are familiar with Bazel, things should work as you expect, e.g.,
run `bazel test //... --keep-going` to run all the tests in the repo,
but we have also added some new aliases in the `justfile` for
convenience:

- `just bazel-test` to run tests locally
- `just bazel-remote-test` to run tests remotely (currently, the remote
build is for x86_64 Linux regardless of your host platform). Note we are
currently seeing the following test failures in the remote build, so we
still need to figure out what is happening here:

```
failures:
    suite::compact::manual_compact_twice_preserves_latest_user_messages
    suite::compact_resume_fork::compact_resume_after_second_compaction_preserves_history
    suite::compact_resume_fork::compact_resume_and_fork_preserve_model_history_view
```

- `just build-for-release` to build release binaries for all
platforms/architectures remotely

To setup remote execution:
- [Create a buildbuddy account](https://app.buildbuddy.io/) (OpenAI
employees should also request org access at
https://openai.buildbuddy.io/join/ with their `@openai.com` email
address.)
- [Copy your API key](https://app.buildbuddy.io/docs/setup/) to
`~/.bazelrc` (add the line `build
--remote_header=x-buildbuddy-api-key=YOUR_KEY`)
- Use `--config=remote` in your `bazel` invocations (or add `common
--config=remote` to your `~/.bazelrc`, or use the `just` commands)

## CI

In terms of CI, this PR introduces `.github/workflows/bazel.yml`, which
uses Bazel to run the tests _locally_ on Mac and Linux GitHub runners
(we are working on supporting Windows, but that is not ready yet). Note
that the failures we are seeing in `just bazel-remote-test` do not occur
on these GitHub CI jobs, so everything in `.github/workflows/bazel.yml`
is green right now.

The `bazel.yml` uses extra config in `.github/workflows/ci.bazelrc` so
that macOS CI jobs build _remotely_ on Linux hosts (using the
`docker://docker.io/mbolin491/codex-bazel` Docker image declared in the
root `BUILD.bazel`) using cross-compilation to build the macOS
artifacts. Then these artifacts are downloaded locally to GitHub's macOS
runner so the tests can be executed natively. This is the relevant
config that enables this:

```
common:macos --config=remote
common:macos --strategy=remote
common:macos --strategy=TestRunner=darwin-sandbox,local
```

Because of the remote caching benefits we get from BuildBuddy, these new
CI jobs can be extremely fast! For example, consider these two jobs that
ran all the tests on Linux x86_64:

- Bazel 1m37s
https://github.com/openai/codex/actions/runs/20861063212/job/59940545209?pr=8875
- Cargo 9m20s
https://github.com/openai/codex/actions/runs/20861063192/job/59940559592?pr=8875

For now, we will continue to run both the Bazel and Cargo jobs for PRs,
but once we add support for Windows and running Clippy, we should be
able to cutover to using Bazel exclusively for PRs, which should still
speed things up considerably. We will probably continue to run the Cargo
jobs post-merge for commits that land on `main` as a sanity check.

Release builds will also continue to be done by Cargo for now.
