e3e5ad2847 Harden unsandboxed patch filesystem access (#39659)
## Why

An `apply_patch` path can be replaced with a symlink after verification, allowing an unsandboxed patch operation to reach a different file than the one that was approved.

## What changed

- Add `follow_symlinks` options to executor filesystem reads, writes, metadata lookups, directory creation, and removal, including the corresponding `followSymlinks` protocol fields.
- Implement no-follow filesystem operations on Unix and Windows that reject links in any path component and restrict file access to regular files.
- Run `apply_patch` with symlink traversal disabled when an otherwise-required sandbox is bypassed, while retaining the existing follow-symlink default for standalone callers.

## Testing

- Cover leaf and ancestor symlinks across patch add, update, delete, and move operations, including a path swap after verification.
- Exercise local and remote no-follow filesystem behavior, concurrent directory creation, special-file rejection, and Windows reparse points.

a1c88e865d Reject duplicate resolved paths in apply_patch (#37867)
## What changed

- Reject patches containing multiple operations whose paths resolve to the same file, such as `duplicate.txt` and `./duplicate.txt`.
- Preserve support for patches that update multiple distinct files.

## Testing

- Add CLI integration coverage for distinct updates and duplicate resolved paths.

c9c6c0daa9 Add a feature flag to preserve apply_patch line endings (#37758)
## What changed

- Add the `apply_patch_preserve_line_endings` feature, disabled by default, to
  preserve CRLF, CR, and mixed line endings when `apply_patch` updates files.
- Apply the feature consistently to built-in patch handling and patches invoked
  through shell, user-shell, unified-exec, and app-server command execution.
- Keep the active feature configuration authoritative over inherited, shell
  snapshot, and client-provided environment values.

## Testing

- Cover line-ending behavior with the feature enabled and disabled for custom
  tool calls, shell heredocs, command execution, and the `apply_patch` CLI.

21aa552e87 Add a line-ending preservation mode to apply_patch (#37757)
## Why

Updating a file with `apply_patch` historically normalized its contents to LF,
which can rewrite line endings outside the requested change.

## What changed

- Add an opt-in `PreserveLineEndings` update mode and thread it through patch
  verification, application, and the standalone executable. Existing APIs keep
  the LF-normalizing mode by default.
- Retain the original endings of untouched and context lines, including in
  mixed-ending files, and use the file's first line ending for inserted or
  replaced lines.
- Track patch context separately from identical changed lines so preservation
  does not alter replacement ordering or matching.

## Testing

Add coverage for CRLF, CR, mixed endings, trailing blank lines, repeated lines,
EOF overlap rejection, and legacy LF normalization.

511262b984 Delegate remote process sandboxing to the executor (#37480)
## What changed

- Preserve executor-native working directories, workspace roots, and permission profiles when preparing remote `exec_command` requests instead of resolving them through the host platform.
- Send sandbox intent to the remote executor, including a restricted-token default for Windows executors and `-NoProfile` for elevated PowerShell commands.
- Reject intercepted cross-platform `apply_patch` commands when filesystem writes are restricted, while continuing to allow them for unsandboxed or full-disk-write profiles.

## Testing

Extended remote unified-exec coverage for foreign Windows workspaces, elevated PowerShell, sandbox metadata, and restricted and unrestricted intercepted patches.

1823c13771 Render turn diffs for foreign environment paths (#34654)
## Why

Turn diffs need to render paths from remote environments whose path convention may differ from the Codex host.

## What changed

- Preserve `PathUri` values through applied patch deltas, display-root discovery, and turn-diff tracking.
- Add host-independent relative-path rendering and normalize Windows drive-letter case in `PathUri`.
- Render paths relative to each environment's repository root while keeping Git diff headers slash-separated.

## Testing

- Cover POSIX, Windows, UNC, encoded-separator, and opaque URI relative paths.
- Verify an applied patch in a remote Windows working directory emits a portable unified diff.

11fab432be path-uri: clarify host-native path conversion (#29501)
## Why

Downstream refactors are producing confusing code with this
functionality having a very generic name. Encoding the specific
conversion approach in the method name makes it clearer.

## What

Rename `PathUri::from_path` to `PathUri::from_host_native_path` and
update its Rust call sites.

0f89dd768c apply-patch: carry paths as PathUri (#28854)
## Why

Allows the model to edit files that are hosted on a different OS than
where app-server is running.

## What

* Use `PathUri` for apply_patch-internal data structures
* Limit `PathUri` -> `AbsolutePathBuf` conversion to cases where the
inferred path convention matches the host OS, allows requiring valid
paths to pass to perms check
* Adds `PathConvention::path_segments()` for iterating over path
segments regardless of OS
* Handle cross-platform relative paths in path filename parsing for
sniffing a shell
* Ensure we can apply patches in the wine e2e test

5867b529ae unified-exec: preserve PathUri through exec-server (#28681)
## Why

It should be possible for app-server to handle "foreign" OS paths in
unified_exec working directories, allowing e.g. a Linux app-server to
run processes on e.g. a Windows exec-server.

## What

Convert the core unified_exec cwd values to use `PathUri`.

Adds fallible path conversion in several places to try to minimize the
scope of this change. The only time this change suppresses errors from
converting `PathUri` to an `AbsolutePathBuf` is when the turn is
configured with no sandboxing at all to allow us to make progress
testing without sandboxing.

Future changes to apply_patch and sandboxing will clean up these error
paths.

A tool's cwd is resolved from joining a model-provided workdir to the
environment's cwd. When using `AbsolutePathBuf::join()`, an
absolute-path workdir would overwrite the environment's cwd and we would
resolve permissions/sandboxing against the model-provided path. This
change extends `PathUri::join()` to also treat an absolute rhs as an
override of the base/lhs.

This also removes some coverage from the remove_env_windows tests until
a follow-up converts foreign paths in command exec events correctly.

## Breaking Changes

When using `AbsolutePathBuf::join()` for workdir resolution, we ended up
resolving tilde-prefixed paths against the app-server's `$HOME`, e.g.
`~/foo/bar` becomes `/home/anp/foo/bar`. It's difficult to do this with
`PathUri` joining, so after offline discussion this PR no longer
implements it.

A quick check of some power users' rollouts suggests that models don't
actually generate home-prefixed absolute working directories for their
spawns, so this shouldn't have any real blast radius.

968a3ac9c1 [codex] make PathUri::from_abs_path infallible (#27976)
## Why

`PathUri::from_abs_path` can fail for absolute paths that do not have a
normal `file:` URI representation, forcing filesystem call sites to
handle a conversion error even though the original path can be preserved
losslessly.

## What

Make `from_abs_path` infallible and migrate its callers. Unrepresentable
paths use `file:///%00/bad/path/<base64>`, encoding Unix bytes or
Windows UTF-16LE; `to_abs_path` validates and decodes that fallback. The
leading encoded null reserves a namespace that cannot collide with a
real Unix or Windows path, and fallback URIs remain opaque to lexical
path operations.

## Validation

Added path-URI coverage for Unix null and non-UTF-8 paths, Windows
device/verbatim and non-Unicode paths, serialization, malformed
fallbacks, opaque lexical operations, invalid native payloads, and
literal `/bad/path` collision resistance.

e26f734f91 [codex] unify apply patch parsing (#27913)
## Why

`apply_patch` maintained separate batch and streaming parsers for the
same patch grammar. That duplicated the parsing rules and allowed final
execution to disagree with the live streamed preview.

## What changed

- Make `StreamingPatchParser` the single owner of hunk and environment
ID parsing.
- Keep heredoc and outer patch-boundary normalization in the existing
`parse_patch` wrapper, preserving its public API.
- Reject non-whitespace content after `*** End Patch` and preserve
separator handling after `*** End of File`.
- Reject duplicate environment ID preambles explicitly.
- Remove the duplicate batch hunk parser and its implementation-specific
tests.

The change removes 201 net lines while retaining focused coverage for
the unified parser's boundary behavior.

## Validation

- `just test -p codex-apply-patch`
- Compared a 24-hour corpus of 2,788,059 observed `apply_patch` payloads
against the previous batch parser. All 2,779,502 accepted payloads
produced identical hunks, canonical patch text, and environment IDs; the
remaining 8,557 payloads were rejected by both parsers, with zero
acceptance or payload mismatches.

b2a4e3be27 [codex] migrate ExecutorFileSystem paths to PathUri (#27424)
## Why

We're moving exec-server to use PathUri for its internal path
representations.

## What

Move `ExecutorFileSystem` APIs to use `PathUri` instead of
`AbsolutePathBuf`. Future changes will convert higher-level parts of
exec-server.

ba2b67f9cd [codex] Consolidate shared prompts in codex-prompts (#25151)
## Why

`codex_core` is consistently a bottleneck for incremental builds during
iteration. The simplest fix is to make the crate smaller.

## Summary

`codex-core` owns several reusable prompt renderers and static prompt
assets, which makes the crate harder to split apart.

Rename `codex-review-prompts` to `codex-prompts` and move shared review,
goal, permissions, compaction, realtime, hierarchical AGENTS.md, and
`apply_patch` prompts into it. Move prompt-only tests and update
consumers and `CODEOWNERS`.

## Validation

- `just test -p codex-prompts -p codex-apply-patch`
- `just test -p codex-core prompt_caching`
- Bazel builds for the affected crates

## Summary
- Bump the workspace Rust toolchain from `1.93.0` to `1.95.0` across
Cargo, Bazel, CI, release workflows, devcontainers, and the Codex
environment config.
- Refresh `MODULE.bazel.lock` so the Bazel Rust toolchain artifacts
match the new version.
- Leave purpose-specific toolchains unchanged, including the
`argument-comment-lint` nightly and the upstream `rusty_v8` `1.91.0`
build pin.
- Includes fixes for new lints from `just fix` and a few codex-authored
fixes for lints without a suggestion.

54ef99a365 Disable empty Cargo test targets (#21584)
## Summary

`cargo test` has entails both running standard Rust tests and doctests.
It turns out that the doctest discovery is fairly slow, and it's a cost
you pay even for crates that don't include any doctests.

This PR disables doctests with `doctest = false` for crates that lack
any doctests.

For the collection of crates below, this speeds up test execution by
>4x.

E.g., before this PR:

```
Benchmark 1: cargo test     -p codex-utils-absolute-path     -p codex-utils-cache     -p codex-utils-cli     -p codex-utils-home-dir     -p codex-utils-output-truncation     -p codex-utils-path     -p codex-utils-string     -p codex-utils-template     -p codex-utils-elapsed     -p codex-utils-json-to-toml
  Time (mean ± σ):      1.849 s ±  4.455 s    [User: 0.752 s, System: 1.367 s]
  Range (min … max):    0.418 s … 14.529 s    10 runs
```

And after:

```
Benchmark 1: cargo test     -p codex-utils-absolute-path     -p codex-utils-cache     -p codex-utils-cli     -p codex-utils-home-dir     -p codex-utils-output-truncation     -p codex-utils-path     -p codex-utils-string     -p codex-utils-template     -p codex-utils-elapsed     -p codex-utils-json-to-toml
  Time (mean ± σ):     428.6 ms ±   6.9 ms    [User: 187.7 ms, System: 219.7 ms]
  Range (min … max):   418.0 ms … 436.8 ms    10 runs
```

For a single crate, with >2x speedup, before:

```
Benchmark 1: cargo test -p codex-utils-string
  Time (mean ± σ):     491.1 ms ±   9.0 ms    [User: 229.8 ms, System: 234.9 ms]
  Range (min … max):   480.9 ms … 512.0 ms    10 runs
```

And after:

```
Benchmark 1: cargo test -p codex-utils-string
  Time (mean ± σ):     213.9 ms ±   4.3 ms    [User: 112.8 ms, System: 84.0 ms]

9b6c6f7a01 fix: preserve exact turn diffs after partial apply_patch failures (#21518)
## Why

Follow-up to #21180: turn diffs are operation-backed now, but a failed
`apply_patch` can still leave exact filesystem mutations behind. For
example, a move can write the destination file before failing to remove
the source. Treating the whole call as unknowable then drops a change
that Codex actually knows happened, so the emitted turn diff can drift
from the workspace.

## What changed

-
[`apply-patch`](f55724e027/codex-rs/apply-patch/src/lib.rs (L248-L345))
now returns `ApplyPatchFailure` with the exact committed prefix
accumulated before an error. If a write failure may already have mutated
the target, the delta is marked inexact instead of being reused blindly.
- Move handling now records the destination write before attempting
source removal, so a partially failed move can still report the
destination file that definitely landed
([code](f55724e027/codex-rs/apply-patch/src/lib.rs (L463-L521))).
-
[`ApplyPatchRuntime`](f55724e027/codex-rs/core/src/tools/runtimes/apply_patch.rs (L49-L67))
now accumulates committed deltas across attempts and forwards them even
when the visible tool result is failed or sandbox-denied ([runtime
path](f55724e027/codex-rs/core/src/tools/runtimes/apply_patch.rs (L223-L250)),
[event
path](f55724e027/codex-rs/core/src/tools/events.rs (L215-L225))).
- `TurnDiffTracker` now consumes committed exact deltas rather than only
fully successful patches; exact-empty failures leave the aggregate
unchanged, while inexact deltas still invalidate it.

## Verification

- Added a regression test covering a failed move that still emits the
committed destination diff:
[`apply_patch_failed_move_preserves_committed_destination_diff`](f55724e027/codex-rs/core/tests/suite/apply_patch_cli.rs (L1517-L1586)).
- Kept explicit coverage that an inexact delta clears the aggregate
instead of publishing a guessed diff:
[`apply_patch_clears_aggregated_diff_after_inexact_delta`](f55724e027/codex-rs/core/tests/suite/apply_patch_cli.rs (L1589-L1655)).

f7e8ff8e50 Make turn diff tracking operation backed (#21180)
## Summary
- replace filesystem-based turn diff tracking with an operation-backed
accumulator
- preserve enough verified apply_patch state to render move-overwrite
cases correctly
- keep the turn/diff/updated contract intact while removing remote-only
turn-diff test skips

This takes the assumption that no 3P services rely on the output format
of `apply_patch`

## Why
For the CCA file system isolation push

c24124b37d Route apply_patch through the environment filesystem (#17674)
## Summary
- route apply_patch runtime execution through the selected Environment
filesystem instead of the local self-exec path
- keep the standalone apply_patch command surface intact while restoring
its launcher/test/docs contract
- add focused apply_patch filesystem sandbox regression coverage

## Validation
- remote devbox Bazel run in progress
- passed: //codex-rs/apply-patch:apply-patch-unit-tests
--test_filter=test_read_file_utf8_with_context_reports_invalid_utf8
- in progress / follow-up: focused core and exec Bazel test slices on
dev

## Follow-up under review
- remote pre-verification and approval/retry behavior still need
explicit scrutiny for delete/update flows
- runtime sandbox-denial classification may need a tighter assertion
path than rendered stderr matching

61dfe0b86c chore: clean up argument-comment lint and roll out all-target CI on macOS (#16054)
## Why

`argument-comment-lint` was green in CI even though the repo still had
many uncommented literal arguments. The main gap was target coverage:
the repo wrapper did not force Cargo to inspect test-only call sites, so
examples like the `latest_session_lookup_params(true, ...)` tests in
`codex-rs/tui_app_server/src/lib.rs` never entered the blocking CI path.

This change cleans up the existing backlog, makes the default repo lint
path cover all Cargo targets, and starts rolling that stricter CI
enforcement out on the platform where it is currently validated.

## What changed

- mechanically fixed existing `argument-comment-lint` violations across
the `codex-rs` workspace, including tests, examples, and benches
- updated `tools/argument-comment-lint/run-prebuilt-linter.sh` and
`tools/argument-comment-lint/run.sh` so non-`--fix` runs default to
`--all-targets` unless the caller explicitly narrows the target set
- fixed both wrappers so forwarded cargo arguments after `--` are
preserved with a single separator
- documented the new default behavior in
`tools/argument-comment-lint/README.md`
- updated `rust-ci` so the macOS lint lane keeps the plain wrapper
invocation and therefore enforces `--all-targets`, while Linux and
Windows temporarily pass `-- --lib --bins`

That temporary CI split keeps the stricter all-targets check where it is
already cleaned up, while leaving room to finish the remaining Linux-
and Windows-specific target-gated cleanup before enabling
`--all-targets` on those runners. The Linux and Windows failures on the
intermediate revision were caused by the wrapper forwarding bug, not by
additional lint findings in those lanes.

## Validation

- `bash -n tools/argument-comment-lint/run.sh`
- `bash -n tools/argument-comment-lint/run-prebuilt-linter.sh`
- shell-level wrapper forwarding check for `-- --lib --bins`
- shell-level wrapper forwarding check for `-- --tests`
- `just argument-comment-lint`
- `cargo test` in `tools/argument-comment-lint`
- `cargo test -p codex-terminal-detection`

## Follow-up

- Clean up remaining Linux-only target-gated callsites, then switch the
Linux lint lane back to the plain wrapper invocation.
- Clean up remaining Windows-only target-gated callsites, then switch
the Windows lint lane back to the plain wrapper invocation.

b77fe8fefe Apply argument comment lint across codex-rs (#14652)
## Why

Once the repo-local lint exists, `codex-rs` needs to follow the
checked-in convention and CI needs to keep it from drifting. This commit
applies the fallback `/*param*/` style consistently across existing
positional literal call sites without changing those APIs.

The longer-term preference is still to avoid APIs that require comments
by choosing clearer parameter types and call shapes. This PR is
intentionally the mechanical follow-through for the places where the
existing signatures stay in place.

After rebasing onto newer `main`, the rollout also had to cover newly
introduced `tui_app_server` call sites. That made it clear the first cut
of the CI job was too expensive for the common path: it was spending
almost as much time installing `cargo-dylint` and re-testing the lint
crate as a representative test job spends running product tests. The CI
update keeps the full workspace enforcement but trims that extra
overhead from ordinary `codex-rs` PRs.

## What changed

- keep a dedicated `argument_comment_lint` job in `rust-ci`
- mechanically annotate remaining opaque positional literals across
`codex-rs` with exact `/*param*/` comments, including the rebased
`tui_app_server` call sites that now fall under the lint
- keep the checked-in style aligned with the lint policy by using
`/*param*/` and leaving string and char literals uncommented
- cache `cargo-dylint`, `dylint-link`, and the relevant Cargo
registry/git metadata in the lint job
- split changed-path detection so the lint crate's own `cargo test` step
runs only when `tools/argument-comment-lint/*` or `rust-ci.yml` changes
- continue to run the repo wrapper over the `codex-rs` workspace, so
product-code enforcement is unchanged

Most of the code changes in this commit are intentionally mechanical
comment rewrites or insertions driven by the lint itself.

## Verification

- `./tools/argument-comment-lint/run.sh --workspace`
- `cargo test -p codex-tui-app-server -p codex-tui`
- parsed `.github/workflows/rust-ci.yml` locally with PyYAML

2fe4be1aa9 fix: codex-arg0 no longer depends on codex-core (#12434)
## Why

`codex-rs/arg0` only needed two things from `codex-core`:

- the `find_codex_home()` wrapper
- the special argv flag used for the internal `apply_patch`
self-invocation path

That made `codex-arg0` depend on `codex-core` for a very small surface
area. This change removes that dependency edge and moves the shared
`apply_patch` invocation flag to a more natural boundary
(`codex-apply-patch`) while keeping the contract explicitly documented.

## What Changed

- Moved the internal `apply_patch` argv[1] flag constant out of
`codex-core` and into `codex-apply-patch`.
- Renamed the constant to `CODEX_CORE_APPLY_PATCH_ARG1` and documented
that it is part of the Codex core process-invocation contract (even
though it now lives in `codex-apply-patch`).
- Updated `arg0`, the core apply-patch runtime, and the `codex-exec`
apply-patch test to import the constant from `codex-apply-patch`.
- Updated `codex-rs/arg0` to call
`codex_utils_home_dir::find_codex_home()` directly instead of
`codex_core::config::find_codex_home()`.
- Removed the `codex-core` dependency from `codex-rs/arg0` and added the
needed direct dependency on `codex-utils-home-dir`.
- Added `codex-apply-patch` as a dev-dependency for `codex-rs/exec`
tests (the apply-patch test now imports the moved constant directly).

## Verification

- `cargo test -p codex-apply-patch`
- `cargo test -p codex-arg0`
- `cargo test -p codex-core --lib apply_patch`
- `cargo test -p codex-exec
test_standalone_exec_cli_can_use_apply_patch`
- `cargo shear`

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.

f6b563ec64 feat: introduce find_resource! macro that works with Cargo or Bazel (#8879)
To support Bazelification in https://github.com/openai/codex/pull/8875,
this PR introduces a new `find_resource!` macro that we use in place of
our existing logic in tests that looks for resources relative to the
compile-time `CARGO_MANIFEST_DIR` env var.

To make this work, we plan to add the following to all `rust_library()`
and `rust_test()` Bazel rules in the project:

```
rustc_env = {
    "BAZEL_PACKAGE": native.package_name(),
},
```

Our new `find_resource!` macro reads this value via
`option_env!("BAZEL_PACKAGE")` so that the Bazel package _of the code
using `find_resource!`_ is injected into the code expanded from the
macro. (If `find_resource()` were a function, then
`option_env!("BAZEL_PACKAGE")` would always be
`codex-rs/utils/cargo-bin`, which is not what we want.)

Note we only consider the `BAZEL_PACKAGE` value when the `RUNFILES_DIR`
environment variable is set at runtime, indicating that the test is
being run by Bazel. In this case, we have to concatenate the runtime
`RUNFILES_DIR` with the compile-time `BAZEL_PACKAGE` value to build the
path to the resource.

In testing this change, I discovered one funky edge case in
`codex-rs/exec-server/tests/common/lib.rs` where we have to _normalize_
(but not canonicalize!) the result from `find_resource!` because the
path contains a `common/..` component that does not exist on disk when
the test is run under Bazel, so it must be semantically normalized using
the [`path-absolutize`](https://crates.io/crates/path-absolutize) crate
before it is passed to `dotslash fetch`.

Because this new behavior may be non-obvious, this PR also updates
`AGENTS.md` to make humans/Codex aware that this API is preferred.

771f1ca6ab fix: accept whitespace-padded patch markers (#8746)
Trim whitespace when validating '*** Begin Patch'/'*** End Patch'
markers in codex-apply-patch so padded marker lines parse as intended,
and add regression coverage (unit + fixture scenario); this avoids
apply_patch failures when models include extra spacing. Tested with
cargo test -p codex-apply-patch.

e61bae12e3 feat: introduce codex-utils-cargo-bin as an alternative to assert_cmd::Command (#8496)
This PR introduces a `codex-utils-cargo-bin` utility crate that
wraps/replaces our use of `assert_cmd::Command` and
`escargot::CargoBuild`.

As you can infer from the introduction of `buck_project_root()` in this
PR, I am attempting to make it possible to build Codex under
[Buck2](https://buck2.build) as well as `cargo`. With Buck2, I hope to
achieve faster incremental local builds (largely due to Buck2's
[dice](https://buck2.build/docs/insights_and_knowledge/modern_dice/)
build strategy, as well as benefits from its local build daemon) as well
as faster CI builds if we invest in remote execution and caching.

See
https://buck2.build/docs/getting_started/what_is_buck2/#why-use-buck2-key-advantages
for more details about the performance advantages of Buck2.

Buck2 enforces stronger requirements in terms of build and test
isolation. It discourages assumptions about absolute paths (which is key
to enabling remote execution). Because the `CARGO_BIN_EXE_*` environment
variables that Cargo provides are absolute paths (which
`assert_cmd::Command` reads), this is a problem for Buck2, which is why
we need this `codex-utils-cargo-bin` utility.

My WIP-Buck2 setup sets the `CARGO_BIN_EXE_*` environment variables
passed to a `rust_test()` build rule as relative paths.
`codex-utils-cargo-bin` will resolve these values to absolute paths,
when necessary.

e290d48264 chore(apply-patch) move invocation parsing (#8110)
lib.rs has grown quite large, and mixes two responsibilities:
1. executing patch operations
2. parsing apply_patch invocations via a shell command

This PR splits out (2) into its own file, so we can work with it more
easily. We are explicitly NOT moving tests in this PR, to ensure
behavior stays the same and we can avoid losing coverage via merge
conflicts. Tests are moved in a subsequent PR.

## Summary
This PR is heavily based on #4017, which contains the core logic for the
fix. To reduce the risk, we are first introducing it only on windows. We
can then expand to wsl / other environments as needed, and then tackle
net new files.

## Testing
- [x] added unit tests in apply-patch
- [x] add integration tests to apply_patch_cli.rs

316352be94 Fix apply_patch rename move path resolution (#5486)
Fixes https://github.com/openai/codex/issues/5485.

Fixed rename hunks so `apply_patch` resolves the destination path using
the verifier’s effective cwd, ensuring patches that run under `cd
<worktree> && apply_patch` stay inside the worktree.

Added a regression test
(`test_apply_patch_resolves_move_path_with_effective_cwd`) that
reproduced the old behavior (dest path resolved in the main repo) and
now passes.

Related to https://github.com/openai/codex/issues/5483.

00c7f7a16c chore: remove once_cell dependency from multiple crates (#4154)
This commit removes the `once_cell` dependency from `Cargo.toml` files
in the `codex-rs` and `apply-patch` directories, replacing its usage
with `std::sync::LazyLock` and `std::sync::OnceLock` where applicable.
This change simplifies the dependency tree and utilizes standard library
features for lazy initialization.
