## What changed
Add optional executor workspace roots to `SandboxTransformRequest` and resolve symbolic workspace rules after merging additional permissions. Preserve explicit deny rules and treat an empty root list as granting no workspace access.
Route Windows restricted-token preparation through the shared transform path and use explicit roots when building its direct-spawn wrapper. Update Windows MXC debug launches to bind configured roots before adding the managed CA read grant.
## Testing
Extend sandbox manager tests to cover workspace and subpath expansion, empty root lists, deny preservation, and the roots and write permissions serialized into the Windows wrapper.
GitOrigin-RevId: 0bebdb08b67cbbc182c18b031b9d13a21a799682
## What changed
Add Linux dependency discovery and policy preparation to `exec-server`'s sandbox integrity module. Inventory bundled and system `bwrap` candidates and the deny-glob scanner using the launcher's location and the command's `PATH` and working directory.
Resolve `:tmpdir` and tilde-prefixed deny globs using the command's `TMPDIR` and `HOME`, with account home-directory fallback. Reuse Linux sandbox helpers to expand deny globs in the command's explicit environment.
## Testing
Add Linux tests covering symlinked launchers, relative and empty `PATH` entries, and empty, relative, and tilde-prefixed `TMPDIR` values alongside home-relative deny globs.
GitOrigin-RevId: fe404fa4be77ece677b22d52d77a7234dbf0cffe
## What changed
Export `FileContentsChecker` and structured integrity findings from `codex-rs/sandboxing` to identify existing containment dependency files whose contents are writable under a prepared filesystem policy. Findings include the requested target, its resolved path, and the write roots that permit modification.
Resolve symlinks in targets, write roots, and read-only carveouts, and respect protected metadata paths and deny globs matching resolved contents. Missing targets produce no finding; non-file targets return an error. Callers remain responsible for dependency inventory, reporting, enforcement, and handling full-disk write access.
## Testing
Add unit tests covering write grants, read-only and denied carveouts, overlapping grants, deny globs, symlink resolution, protected metadata, and missing targets.
GitOrigin-RevId: 4f52faed822a1bbb4ed33a9975af0718a5f85662
## Why
Bubblewrap discovery probes executables before confinement. Excluding only the command's current directory leaves candidates in other writable roots eligible to run outside the sandbox.
## What changed
- Filter canonical `PATH` candidates using the filesystem policy and effective user permissions, including writable ancestors, symlinked roots, and full-disk write access. Preserve protected system installations while rejecting replaceable paths.
- Select the launcher with the command's permissions before the proc-mount preflight, retaining the bundled bubblewrap fallback.
- Use the effective permission profile and policy working directory for startup warning probes.
## Testing
Add unit coverage for writable roots, symlinks, read-only carveouts, replaceable parents, and full-disk policies. Add Linux integration tests showing writable `bwrap` candidates are neither probed nor launched, including when the command runs in a workspace subdirectory or uses managed networking with full-disk write access.
GitOrigin-RevId: 188c9f45e727eaace062f5abb1205dc23fdf3c51
## Why
When a container denies fresh `/proc` mounts, the existing sandbox fallback retains the caller's `/proc` while creating a new PID namespace. Process IDs inside the sandbox can then differ from those exposed by `/proc`, breaking process lookups.
## What changed
- Add `codex exec-server --linux-sandbox-pid-namespace=inherit` to reuse the caller's PID namespace and `/proc` for both process and filesystem helpers. Repository config and command environment variables cannot enable it.
- Keep `isolate` as the default, preserving the existing mount fallback and compatibility with older helpers. Inheritance requires an updated helper and omits `--unshare-pid` and `--as-pid-1`.
- Preserve other sandbox restrictions. With `:minimal`, bind the inherited `/proc` read-only with its container masks and apply explicit filesystem denials afterward.
Inheritance is intended for dedicated environments: it allows sandboxed commands to signal other same-UID processes, including the executor.
## Testing
Add unit and integration coverage for namespace flags, denied proc mounts, consistent process IDs, retained sandbox restrictions, and startup-only selection across process and filesystem helpers.
GitOrigin-RevId: dd13f2b9286d7edcf366b3a42a455f4d78daaf27
## What changed
- Add explicit MXC backend selection and carry its identity through exec-server process reporting and sandbox violation classification.
- Launch MXC through the Codex executable with the effective permission profile and command environment.
- Reject exec-server MXC requests when native MXC is unavailable or when they request a TTY, an `arg0` override, or managed networking. Reject private desktop isolation during MXC preparation.
- Allow an explicitly empty child environment and avoid exposing request payload values in launcher decode errors.
## Testing
Add coverage for sandbox selection and unsupported-request rejection, plus Windows RPC tests for stdin writes and temporary-directory permissions derived from the command environment. Native MXC tests skip when MXC is unavailable.
GitOrigin-RevId: 3626ff0f9ad7f9b812ce09b68c31ea9a5a9c72b1
## What changed
- Dispatch `--__codex-windows-mxc` before normal CLI parsing, launch the decoded request, and propagate the child exit code.
- Build the native request from the helper's environment and working directory, discovered Windows platform directories, and volume roots, including UNC working-directory roots. Reject non-Unicode environment values and empty child environments.
- Allow Win32k calls and desktop handles needed for PowerShell startup while retaining clipboard, input-injection, and desktop/system-control restrictions.
- Keep policy, transport, and native launch internals private, and report an explicit error when the helper is invoked outside Windows.
## Testing
Add a wrapper regression test covering exact argument preservation, Windows quoting, separate policy and command working directories, and explicit environment forwarding.
GitOrigin-RevId: 674d0d61a3265bd517b77da9f9de2cd9fad62917
## What changed
- Probe whether the native Windows MXC process security environment is usable
when selecting a sandbox.
- Emit `codex.windows_mxc.available` at most once per process, labeled with the
probe result.
- Add the MXC workspace dependencies for Cargo and Bazel, and pin
`tracelogging` to a version compatible with the GNU Windows toolchain.
GitOrigin-RevId: d7cfeed6f0333feda5764e1ee44fe5bbd50f9a58
## Why
Programs running in a PTY can block while waiting for replies to terminal
queries.
## What changed
- Intercept device-status, window-size, cursor-position, and DEC private-mode
queries from TTY subprocess output and write bounded responses to the
subprocess input.
- Remove handled queries from the output stream while preserving other escape
sequences and output, including queries split across chunks.
- Apply the responder to both direct and driver-backed TTY process spawning.
## Testing
Added tests for driver-backed query handling and for a PTY subprocess that
waits for a cursor-position response before exiting.
GitOrigin-RevId: de92e06d183647271ef49024da9c30f01699f886
## Why
A sandboxed process could replace a writable directory root, changing the
authority boundary used to construct a later sandbox policy.
## What changed
- Deny unlinking or renaming directory roots granted write access by Seatbelt,
while preserving replacement and deletion behavior for writable files.
- Reject writable roots with nested symlink components and report these as
Seatbelt preparation errors instead of network proxy failures.
- Normalize writable roots before adding them to the generated Seatbelt policy.
## Testing
Add coverage for symlink rejection, error classification, directory-root
replacement and rename protection, newly created roots, and writable file
replacement.
GitOrigin-RevId: ab1ed4e55f20034bc43e028e6529d3d1f0d8181c
## Why
Cross-platform remote `apply_patch` calls were rejected when filesystem writes
were restricted because patch verification and writes could not be safely
performed against executor files.
## What changed
- Route intercepted and direct remote patches through the executor-managed
filesystem sandbox, including the configured workspace roots.
- Select the restricted-token sandbox for Windows executor paths when no
Windows sandbox level was configured.
- Fail closed when an executor cannot enforce the requested sandbox, and treat
executor-managed access failures as sandbox denials so approval can retry the
patch without sandboxing.
## Testing
- Cover sandboxed remote patches, denied writes, approval retries, Windows
sandbox selection, and executor filesystem enforcement.
GitOrigin-RevId: caddeed0b266c456a689080a14a3a58e2bd7887c
## Why
Filesystem denials and managed-network blocks did not share a structured event
shape, requiring downstream consumers to rediscover enforcement paths and parse
backend-specific output. See https://github.com/openai/codex/pull/17573.
## What changed
- Add normalized filesystem and network violation types in `codex-sandboxing`
and emit them through a shared tracing seam.
- Classify filesystem denials by backend and reason, retaining an optional path
and bounded output snippet, and preserve managed-network block context.
- Report the sandbox type through exec-server responses so unified exec can
classify remote denials without guessing; omitted values remain compatible
with older peers.
- Record violations from exec, apply-patch, shell-escalation, unified-exec, and
managed-network enforcement paths without changing denial behavior.
## Testing
- Cover filesystem classification, path extraction, `SIGSYS`, network event
conversion, protocol compatibility, and remote sandbox-type propagation.
GitOrigin-RevId: d673173b4fa6bdf0a24421194a8a61c81fab9c96
## Why
Sandboxed process launch through the exec server was unsupported on Windows.
## What changed
- Add a shared native process launcher that selects the Windows sandbox session backend when required and otherwise launches PTY or pipe-based processes.
- Pass Windows permission, workspace-root, proxy, filesystem-override, and desktop settings through exec-server process preparation.
- Preserve piped stdin and inherited file descriptors across the shared launch path.
## Testing
- Verify that a remote Windows sandbox process accepts stdin while blocking a write under a read-only policy.
- Enable workspace-root sandbox tests on native Windows while continuing to skip environments that cannot emulate Windows sandbox semantics.
GitOrigin-RevId: 6719ccbe87ad0d5a57af56503e3f23f894c60a71
## Why
Filesystem helpers intentionally run with a minimal environment that
excludes proxy variables. After filesystem operations started using the
Windows sandbox wrapper, the wrapper derived an empty proxy
configuration from that helper environment and compared it with the
persistent sandbox setup marker. When the marker contained proxy ports,
every filesystem operation appeared to require a firewall update, which
could launch elevated setup, show a UAC or loader dialog, and fail
operations such as `apply_patch` with error 1223.
Filesystem helpers do not use network access, so they should preserve
the proxy/firewall state established by normal sandboxed process
launches.
## What changed
- Add an explicit Windows sandbox proxy-settings mode for reconciling or
preserving persistent proxy state.
- Use preserve mode for filesystem helpers while normal process launches
continue to reconcile proxy settings from their environment.
- Carry the selected proxy state consistently through setup validation,
elevated setup, and non-elevated ACL refreshes.
- Cover wrapper argument propagation and marker-derived proxy
preservation.
## Validation
- `cargo build -p codex-cli --bin codex`
- `just test -p codex-windows-sandbox
preserving_proxy_settings_uses_the_existing_marker`
- `just test -p codex-windows-sandbox windows_wrapper_args_round_trip`
- `just test -p codex-windows-sandbox
setup_request_prefers_explicit_proxy_settings`
- `just test -p codex-sandboxing transform_for_direct_spawn_windows`
- `just test -p codex-exec-server fs_sandbox::tests`
- Ran the same sandboxed `fs/writeFile` reproduction against published
`0.142.0-alpha.6` and the new CLI. The published CLI launched elevated
setup and failed with `ShellExecuteExW ... 1223`; the new CLI completed
without elevation.
Related to #28359.
## Why
#29113 moved remote sandbox setup and enforcement to the exec server.
That gives the executor ownership of the platform-specific work: a Linux
executor chooses and runs a Linux sandbox even when the Codex
orchestrator is running on macOS or Windows.
It also means the orchestrator no longer knows which concrete sandbox
the executor selected. When that sandbox blocks a remote command, the
orchestrator currently sees only a failed process and can treat the
denial as an ordinary command failure. The existing sandbox approval and
retry path is then skipped.
This PR lets the executor report one portable fact:
> This command probably failed because the executor sandbox blocked it.
The executor keeps its concrete sandbox type private. The protocol sends
only the semantic result.
## Example
Suppose a local macOS Codex session asks a Linux devbox to write outside
the allowed workspace.
Before this PR:
```text
Linux sandbox blocks the write
-> remote process exits with "Permission denied"
-> local orchestrator sees an ordinary command failure
-> the normal sandbox approval and retry path can be skipped
```
With this PR:
```text
Linux sandbox blocks the write
-> executor reports sandboxDenied: true
-> unified exec returns UnifiedExecError::SandboxDenied
-> the existing approval prompt is shown
-> an approved retry runs through the existing unsandboxed retry path
```
## What changes
### The executor remembers its selected sandbox
The prepared remote process now retains the executor-selected
`SandboxType`. This value never crosses the executor boundary.
Commands started without a sandbox retain `SandboxType::None` and are
never reported as sandbox denials.
### The executor uses the existing denial heuristic
The existing local denial heuristic moves from `codex-core` into the
shared `codex-sandboxing` crate.
When a sandboxed remote process exits, the executor:
1. waits the same short output grace period used by local unified exec;
2. reads the output currently available in the existing retained output
buffer;
3. runs the existing heuristic using the exit code and common denial
messages;
4. stores the yes/no result before publishing the process exit.
This deliberately matches the old local unified-exec behavior. It does
not add a new streaming classifier, another output buffer, or stronger
output-retention guarantees.
### The protocol reports a portable boolean
`process/read` gains `sandboxDenied`:
```json
{
"exited": true,
"exitCode": 1,
"closed": false,
"sandboxDenied": true
}
```
The field defaults to `false` when an older executor omits it. The
response does not expose the executor sandbox implementation or
executor-native paths.
### Unified exec uses the existing error path
The exec-server client carries `sandboxDenied` into the unified process
state. If it is true, unified exec returns the existing `SandboxDenied`
error instead of trying to classify remote output using an
orchestrator-side sandbox type.
Remote process exit remains visible as soon as the process exits. This
PR does not wait for stdout or stderr to close and does not change the
existing process lifecycle.
## Scope
This PR is intentionally limited to matching the existing local
unified-exec behavior for the initial command execution path.
It does not add:
- incremental denial tracking across the full output stream;
- new denial handling for commands completed later through
`write_stdin`;
- new guarantees for preserving the semantic flag during the narrow
reconnect-recovery race.
Those can be considered separately if the same behavior is added for
local execution.
## Test coverage
One remote end-to-end integration test covers the complete intended
flow:
```text
remote read-only sandbox
-> denied write
-> executor reports the denial
-> Codex requests approval
-> user approves
-> retry succeeds on the remote executor
```
Existing lifecycle coverage continues to verify that remote process exit
is reported before late output streams close.
Stacked on #28766.
## Why
Network approvals are environment-scoped: allowing a host in one
execution environment should not allow the same host in another
environment.
#28766 adds the inert IDs and constructor plumbing. This PR applies the
behavior on top.
## What changed
- Route managed network traffic through per-environment HTTP and SOCKS
proxy listeners.
- Stamp HTTP, HTTPS CONNECT, SOCKS TCP, and SOCKS UDP policy requests
with the source environment at the proxy boundary.
- Carry the selected execution environment through shell, unified exec,
zsh-fork, and sandbox transform paths.
- Include the environment in pending, approved-for-session, and
denied-for-session network approval cache keys.
- Include the environment in approval IDs and approval prompts.
- Preserve legacy fallback for unattributed requests, but deny when
active-call attribution is ambiguous.
- Fail closed if an environment-specific proxy endpoint cannot be
prepared.
## Validation
- just fmt
- CI will run tests and clippy
## Why
This is the final PR in the Windows fs-helper sandbox stack and contains
the actual bug fix.
The exec-server filesystem helper is a direct-spawn path: it asks
`SandboxManager` for a `SandboxExecRequest`, then launches the returned
argv itself. That works on macOS and Linux because the transformed argv
is already a self-contained sandbox wrapper. On Windows, the transformed
request carried `WindowsRestrictedToken` metadata, but the direct-spawn
fs-helper runner still launched the helper argv directly.
That means Windows filesystem built-ins backed by the fs-helper could
run with the parent Codex process permissions instead of the configured
Windows sandbox. This PR makes the direct-spawn transform produce a
self-contained Windows wrapper argv before fs-helper launches it.
## What Changed
- Added `SandboxManager::transform_for_direct_spawn()` for callers that
launch the returned argv themselves.
- Wrapped Windows restricted-token direct-spawn requests with `codex.exe
--run-as-windows-sandbox` and then marked the outer request as
unsandboxed, matching the macOS/Linux wrapper argv shape.
- Updated `exec-server/src/fs_sandbox.rs` to use the direct-spawn
transform for fs-helper launches.
- Materialized the inner `codex.exe --codex-run-as-fs-helper` executable
into `.sandbox-bin` so the sandboxed user can run it.
- Carried runtime workspace roots through `FileSystemSandboxContext` as
`PathUri` values so `:workspace_roots` policies resolve correctly
without sending native client paths over exec-server JSON.
- Preserved wrapper setup identity environment needed by Windows sandbox
setup without changing the serialized inner helper environment.
## Verification
- `just bazel-lock-update`
- `just bazel-lock-check`
- `just test -p codex-sandboxing transform_for_direct_spawn_windows`
- `just test -p codex-exec-server fs_sandbox::tests`
- `just fix -p codex-windows-sandbox -p codex-sandboxing -p
codex-exec-server -p codex-core -p codex-file-system`
Local note: `just fmt` completed Rust formatting, but this workstation
still fails the non-Rust formatter phases because uv cannot open its
cache and the local buildifier/dotslash path is missing.
## Why
Sandbox cwd values can cross app-server and exec-server host boundaries.
They should retain URI semantics until the receiving host validates them
instead of being interpreted early as native paths.
## What
- Carry `PathUri` through filesystem sandbox contexts, sandbox commands,
and transform inputs.
- Convert command and policy cwd once in `SandboxManager::transform`,
then keep launch requests native.
- Preserve sandbox cwd over remote filesystem transport and reject
non-native URIs without fallback.
- Cache paired native/URI turn-environment cwd values during migration,
with immutable access to keep them synchronized.
- Extend existing protocol, forwarding, transform, and core runtime
tests.
## Stack
1. Parent PR: #18240 uses named MITM permissions config.
2. This PR wires managed MITM CA trust into spawned child processes.
## Why
When Codex terminates HTTPS for limited mode or MITM hooks, child HTTPS
clients need to trust Codex's managed MITM CA. Exporting proxy URLs
alone is not enough, but blindly replacing user CA settings would be
wrong: it can break custom enterprise/test roots, leak unreadable CA
files into generated bundles, or make the child env disagree with its
sandbox policy.
## Summary
1. Build immutable managed CA bundles under `$CODEX_HOME/proxy` that
include native roots, the managed MITM CA, and only inherited or
command-scoped CA bundles the child is allowed to read.
2. Export curated CA env vars alongside managed proxy env vars while
preserving user CA override semantics, including nested Codex
`SSL_CERT_FILE` precedence.
3. Thread generated CA bundle paths into child sandbox readable roots,
including debug sandbox execution, so the exported env vars work inside
sandboxed commands.
4. Remove only Codex-generated MITM CA bundle env when a child
intentionally drops managed proxying for escalation or no-proxy retry.
5. Document the managed CA bundle behavior and cover env injection,
per-child bundle generation, sandbox readable roots, and no-proxy
cleanup in tests.
## Validation
1. Ran `just test -p codex-network-proxy`.
2. Ran `just test -p codex-protocol`.
3. Ran `just fix -p codex-network-proxy -p codex-protocol`.
4. Tried focused `codex-core` validation, but the crate currently fails
to compile in `core/tests/suite/guardian_review.rs` because an existing
`Op::UserInput` initializer is missing `additional_context`.

## Why
This supersedes #19391. During stack repair, GitHub marked #19391 as
merged into a temporary stack branch rather than into `main`, so the
runtime-config change needed a fresh PR.
`PermissionProfile` is now the canonical permissions shape after #19231
because it can distinguish `Managed`, `Disabled`, and `External`
enforcement while also carrying filesystem rules that legacy
`SandboxPolicy` cannot represent cleanly. Core config and session state
still needed to accept profile-backed permissions without forcing every
profile through the strict legacy bridge, which rejected valid runtime
profiles such as direct write roots.
The unrelated CI/test hardening that previously rode along with this PR
has been split into #19683 so this PR stays focused on the permissions
model migration.
## What Changed
- Adds `Permissions.permission_profile` and
`SessionConfiguration.permission_profile` as constrained runtime state,
while keeping `sandbox_policy` as a legacy compatibility projection.
- Introduces profile setters that keep `PermissionProfile`, split
filesystem/network policies, and legacy `SandboxPolicy` projections
synchronized.
- Uses a compatibility projection for requirement checks and legacy
consumers instead of rejecting profiles that cannot round-trip through
`SandboxPolicy` exactly.
- Updates config loading, config overrides, session updates, turn
context plumbing, prompt permission text, sandbox tags, and exec request
construction to carry profile-backed runtime permissions.
- Preserves configured deny-read entries and `glob_scan_max_depth` when
command/session profiles are narrowed.
- Adds `PermissionProfile::read_only()` and
`PermissionProfile::workspace_write()` presets that match legacy
defaults.
## Verification
- `cargo test -p codex-core direct_write_roots`
- `cargo test -p codex-core runtime_roots_to_legacy_projection`
- `cargo test -p codex-app-server
requested_permissions_trust_project_uses_permission_profile_intent`

## Summary
- adds macOS Seatbelt deny rules for unreadable glob patterns
- expands unreadable glob matches on Linux and masks them in bwrap,
including canonical symlink targets
- keeps Linux glob expansion robust when `rg` is unavailable in minimal
or Bazel test environments
- adds sandbox integration coverage that runs `shell` and `exec_command`
with a `**/*.env = none` policy and verifies the secret contents do not
reach the model
## Linux glob expansion
```text
Prefer: rg --files --hidden --no-ignore --glob <pattern> -- <search-root>
Fallback: internal globset walker when rg is not installed
Failure: any other rg failure aborts sandbox construction
```
```
[permissions.workspace.filesystem]
glob_scan_max_depth = 2
[permissions.workspace.filesystem.":project_roots"]
"**/*.env" = "none"
```
This keeps the common path fast without making sandbox construction
depend on an ambient `rg` binary. If `rg` is present but fails for
another reason, the sandbox setup fails closed instead of silently
omitting deny-read masks.
## Platform support
- macOS: subprocess sandbox enforcement is handled by Seatbelt regex
deny rules
- Linux: subprocess sandbox enforcement is handled by expanding existing
glob matches and masking them in bwrap
- Windows: policy/config/direct-tool glob support is already on `main`
from #15979; Windows subprocess sandbox paths continue to fail closed
when unreadable split filesystem carveouts require runtime enforcement,
rather than silently running unsandboxed
## Stack
1. #15979 - merged: cross-platform glob deny-read
policy/config/direct-tool support for macOS, Linux, and Windows
2. This PR - macOS/Linux subprocess sandbox enforcement plus Windows
fail-closed clarification
3. #17740 - managed deny-read requirements
## Verification
- Added integration coverage for `shell` and `exec_command` glob
deny-read enforcement
- `cargo check -p codex-sandboxing -p codex-linux-sandbox --tests`

## Summary
- detect WSL1 before Codex probes or invokes the Linux bubblewrap
sandbox
- fail early with a clear unsupported-operation message when a command
would require bubblewrap on WSL1
- document that WSL2 follows the normal Linux bubblewrap path while WSL1
is unsupported
## Why
Codex 0.115.0 made bubblewrap the default Linux sandbox. WSL1 cannot
create the user namespaces that bubblewrap needs, so shell commands
currently fail later with a raw bwrap namespace error. This makes the
unsupported environment explicit and keeps non-bubblewrap paths
unchanged.
The WSL detection reads /proc/version, lets an explicit WSL<version>
marker decide WSL1 vs WSL2+, and only treats a bare Microsoft marker as
WSL1 when no explicit WSL version is present.

Addresses #15282
Problem: Codex warned about missing system bubblewrap even when
sandboxing was disabled.
Solution: Gate the bwrap warning on the active sandbox policy and skip
it for danger-full-access and external-sandbox modes.
## 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`

## Why
`PermissionProfile` should only describe the per-command permissions we
still want to grant dynamically. Keeping
`MacOsSeatbeltProfileExtensions` in that surface forced extra macOS-only
approval, protocol, schema, and TUI branches for a capability we no
longer want to expose.
## What changed
- Removed the macOS-specific permission-profile types from
`codex-protocol`, the app-server v2 API, and the generated
schema/TypeScript artifacts.
- Deleted the core and sandboxing plumbing that threaded
`MacOsSeatbeltProfileExtensions` through execution requests and seatbelt
construction.
- Simplified macOS seatbelt generation so it always includes the fixed
read-only preferences allowlist instead of carrying a configurable
profile extension.
- Removed the macOS additional-permissions UI/docs/test coverage and
deleted the obsolete macOS permission modules.
- Tightened `request_permissions` intersection handling so explicitly
empty requested read lists are preserved only when that field was
actually granted, avoiding zero-grant responses being stored as active
permissions.
## Summary
- move the bwrap PATH lookup and warning helpers out of config/mod.rs
- move the related tests into a dedicated bwrap_tests.rs file
## Validation
- git diff --check
- skipped heavier local tests per request
Follow-up to #15791.
## Summary
- move the pure sandbox policy transform helpers from `codex-core` into
`codex-sandboxing`
- move the corresponding unit tests with the extracted implementation
- update `core` and `app-server` callers to import the moved APIs
directly, without re-exports or proxy methods
## Testing
- cargo test -p codex-sandboxing
- cargo test -p codex-core sandboxing

## Summary
- move macOS permission merging/intersection logic and tests from
`codex-core` into `codex-sandboxing`
- move seatbelt policy builders, permissions logic, SBPL assets, and
their tests into `codex-sandboxing`
- keep `codex-core` owning only the seatbelt spawn wrapper and switch
call sites to import the moved APIs directly
## Notes
- no re-exports added
- moved the seatbelt tests with the implementation so internal helpers
could stay private
- local verification is still finishing while this PR is open
## Summary
- add a new `codex-sandboxing` crate for sandboxing extraction work
- move the pure Linux sandbox argv builders and their unit tests out of
`codex-core`
- keep `core::landlock` as the spawn wrapper and update direct callers
to use `codex_sandboxing::landlock`
## Testing
- `cargo test -p codex-sandboxing`
- `cargo test -p codex-core landlock`
- `cargo test -p codex-cli debug_sandbox`
- `just argument-comment-lint`
## Notes
- this is step 1 of the move plan aimed at minimizing per-PR diffs
- no re-exports or no-op proxy methods were added
