## Why
Patch targets can use a different path convention from the Codex host, so
host-native path conversion can misclassify writable roots and requested
permissions.
## What changed
- Evaluate patch targets as `PathUri` values with the active filesystem policy
context, including workspace roots and the executor's path convention.
- Distinguish executor-managed sandboxing from local platform sandboxing when
deciding whether a patch can be auto-approved and how to normalize additional
write permissions.
- Make full-disk and special-path policy checks honor the selected executor's
Windows or POSIX convention.
## Testing
Add coverage for Windows executor URIs, full-disk policy aliases, remote patch
permission requests, sandbox availability, and owner-provided workspace roots.

## Why
Tool actions and approval retries can outlive the step that issued them. If approval handling reads newer turn settings, a delayed action can use the wrong approval policy or reviewer.
## What changed
- Capture the approval policy and reviewer in `GuardianReviewContext` from the issuing step.
- Use step settings for command, patch, permission, sandbox-retry, and remote-network approval decisions.
- Use the active task's published settings for background network approvals and long-lived Unix shell interception.
- Preserve explicit MCP reviewer overrides.
## Testing
Added regression coverage for permission requests, same-turn network policy changes, delayed commands after a new turn starts, sandbox retries, patch policy selection, and MCP reviewer overrides.

## 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.
## 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
- Migrate apply-patch verification and application internals to use the
async `ExecutorFileSystem` abstraction from `exec-server`.
- Convert apply-patch `cwd` handling to `AbsolutePathBuf` through the
verifier/parser/handler boundary.
Doesn't change how the tool itself works.
## Why
PR #13783 moved the `codex.rs` unit tests into `codex_tests.rs`. This
applies the same extraction pattern across the rest of `codex-rs/core`
so the production modules stay focused on runtime code instead of large
inline test blocks.
Keeping the tests in sibling files also makes follow-up edits easier to
review because product changes no longer have to share a file with
hundreds or thousands of lines of test scaffolding.
## What changed
- replaced each inline `mod tests { ... }` in `codex-rs/core/src/**`
with a path-based module declaration
- moved each extracted unit test module into a sibling `*_tests.rs`
file, using `mod_tests.rs` for `mod.rs` modules
- preserved the existing `cfg(...)` guards and module-local structure so
the refactor remains structural rather than behavioral
## Testing
- `cargo test -p codex-core --lib` (`1653 passed; 0 failed; 5 ignored`)
- `just fix -p codex-core`
- `cargo fmt --check`
- `cargo shear`
