pakrym-oaiandGitHub f3c1283411 Pair thread environment settings (#26687)
## Why

Thread cwd and environment selections are a single logical setting in
core: updating one without the other can silently desynchronize the
next-turn execution context. This change makes that relationship
explicit in the internal thread settings flow while preserving the
existing app-server public API shape.

## What changed

- Moved the cwd/environment pair through internal
`ThreadSettingsOverrides.environment_settings` instead of a top-level
internal `cwd` field.
- Kept `thread/settings/update` public params unchanged, with app-server
translating top-level `cwd` into the paired internal settings shape.
- Moved `Op::UserInput` environment overrides into thread settings so
user turns and settings updates use the same core path.
- Updated core, app-server, MCP, memories, sample, and test callsites to
construct the paired settings shape.

## Verification

- `git diff --check`
- Local test run starting after PR creation.

pakrym-oaiandGitHub 40c8f1a007 Require absolute cwd in thread settings (#26532)
## Why

Thread settings cwd overrides are expected to be resolved before they
enter core. Keeping this boundary as a plain `PathBuf` made it easy for
core/session code to keep fallback normalization and relative-path
resolution logic in places that should only receive an already-resolved
cwd.

This is intentionally the absolute-cwd-only slice: it does not change
environment selection stickiness or cwd-to-default-environment fallback
behavior.

## What changed

- Changes `ThreadSettingsOverrides.cwd`,
`CodexThreadSettingsOverrides.cwd`, and `SessionSettingsUpdate.cwd` to
use `AbsolutePathBuf`.
- Removes core-side cwd normalization/resolution from session settings
updates.
- Updates affected core/app-server test helpers and callsites to pass
existing absolute cwd values or use `abs()` helpers.

## Validation

Opening as draft so CI can start while local validation continues.

joeflorencio-openaiandGitHub d45cd26248 Switch runtime to cloud config bundle (#24622)
## Summary

- Adapts the moved `codex-cloud-config` crate from the legacy cloud
requirements endpoint to the new config bundle endpoint.
- Switches runtime consumers from `CloudRequirementsLoader` to
`CloudConfigBundleLoader` so one shared bundle supplies cloud-delivered
config and requirements.
- Removes the legacy cloud requirements domain loader path.

## Details

This intentionally keeps `codex-cloud-config` monolithic for review
lineage: the previous PR establishes the crate move, and this PR shows
the behavior change against that moved implementation. A follow-up PR
splits the module back into focused files.

The new bundle path preserves the important cloud requirements loader
semantics where intended: account-scoped signed cache, 30 minute TTL, 5
minute refresh cadence, retry/backoff, auth recovery, and fail-closed
startup loading. The cached payload changes from a single requirements
TOML string to the backend-delivered bundle, and validation rejects
malformed config or requirements fragments before cache write/use.

Michael BolinandGitHub 6e10142199 fix: preserve deny-read sandboxing for safe commands (#23943)
## Why

Permission profiles can mark filesystem entries as unreadable with
`deny` rules, including glob patterns. Several shell execution paths
treated known-safe commands or execpolicy `allow` rules as sufficient to
run outside the filesystem sandbox. That is not valid for read-capable
commands: for example, `cat` or `ls` may be reasonable to allow
generally, but dropping the sandbox would also drop deny-read
constraints such as `**/*.env`.

## What changed

- Added a shared check that treats active deny-read restrictions as
incompatible with unsandboxed execution.
- Kept first-attempt execution sandboxed for explicit escalation and
execpolicy allow bypasses when deny-read entries are present.
- Prevented no-sandbox retry after a sandbox denial when the active
filesystem policy contains deny-read entries.
- Updated the zsh-fork execve path so prefix-rule `allow` decisions
continue inside the current sandbox when deny-read restrictions are
active.

## Verification

Michael BolinandGitHub bc10e5b390 runtime: prepend zsh fork bin dir to PATH (#23768)
## Why

#23756 makes packaged Codex builds include and default to the bundled
zsh fork. The important reason to put that fork's directory at the front
of `PATH` is to keep executable-level escalation working after a command
leaves the original shell and later re-enters zsh through `env`.

The expected chain is:

1. The zsh fork runs the top-level shell command.
2. That command launches another program, such as `python3`, while
inheriting the `EXEC_WRAPPER` environment and the escalation socket fd.
3. That program spawns a shell script whose shebang is `#!/usr/bin/env
zsh` rather than `#!/bin/zsh`, and it does not close the escalation fd.
4. `/usr/bin/env` resolves `zsh` through `PATH`, so it must find the
packaged zsh fork before the system zsh.
5. Commands inside that nested script are intercepted by the zsh fork
and can still request escalation from Codex.

If `PATH` resolves `zsh` to the system shell instead, the nested script
loses zsh-fork exec interception. Commands that should request
escalation can then run only in the original sandbox, or fail there,
without Codex ever receiving the approval request.

Shell snapshots make this slightly more subtle: a snapshot can restore
an older `PATH` after the child shell starts. This PR treats the zsh
fork `PATH` prepend as an explicit environment override so snapshot
wrapping preserves it.

## What Changed

- Added shared zsh-fork runtime helpers that prepend the configured zsh
executable parent directory to `PATH` without duplicate entries.
- Applied the zsh fork `PATH` prepend to both zsh-fork `shell_command`
launches and unified-exec zsh-fork launches before sandbox command
construction.
- Kept the shell-command zsh-fork backend API narrow: it derives the
configured zsh path from session services and rebuilds its sandbox
environment from `req.env`, rather than accepting a second, competing
environment map or a separately threaded bin dir.
- Kept Unix-only zsh-fork `PATH` mutation out of Windows clippy-visible
mutability.
- Added coverage for duplicate `PATH` entries, for preserving the zsh
fork prepend through shell snapshot wrapping, and for the nested
`python3` -> `#!/usr/bin/env zsh` escalation flow.

## Testing

- `just fmt`
- `just fix -p codex-core`

I left final test validation to CI after the latest review-comment
cleanup. Before that cleanup, `just test -p codex-core zsh_fork` passed
locally for the zsh-fork-focused tests.

pakrym-oaiandGitHub 768848ab6f Add experimental turn additional context (#24154)
## Summary

Adds experimental `additionalContext` support to `turn/start` and
`turn/steer` so clients can provide ephemeral external context, such as
browser or automation state, without turning that plumbing into a
visible user prompt or triggering user-prompt lifecycle behavior.

## API Shape

The parameter shape is:

```ts
additionalContext?: Record<string, {
  value: string
  kind: "untrusted" | "application"
}> | null
```

Example:

```json
{
  "additionalContext": {
    "browser_info": {
      "value": "Active tab is CI failures.",
      "kind": "untrusted"
    },
    "automation_info": {
      "value": "CI rerun is in progress.",
      "kind": "application"
    }
  }
}
```

The keys are opaque and caller-defined.

## Context Injection

When provided, accepted entries are inserted into model context as
hidden contextual message items, not as visible thread user-message
items.

`kind: "untrusted"` entries are inserted with role `user`:

```text
<external_${key}>${value}</external_${key}>
```

`kind: "application"` entries are inserted with role `developer`:

```text
<${key}>${value}</${key}>
```

Values are not escaped. Each value is truncated to 1k approximate tokens
before wrapping.

For `turn/start`, accepted additional context is inserted before normal
user input. For `turn/steer`, additional context is merged only when the
steer includes non-empty user input; context-only steers still reject as
empty input.

## Dedupe Strategy

`AdditionalContextStore` lives on session state and stores the latest
complete additional-context map.

Each `turn/start` or non-empty `turn/steer` treats its
`additionalContext` as the current complete set of values. Entries are
injected only when the key is new or the exact entry for that key
changed, including `value` or `kind`. After merging, the store is
replaced with the provided map, so omitted keys are removed from the
retained set and can be injected again later if reintroduced.

Omitting `additionalContext`, passing `null`, or passing an empty object
resets the store to empty and injects nothing.

## What Changed

- Threads experimental v2 `additionalContext` through app-server into
core turn start and steer handling.
- Adds separate contextual fragment types for untrusted user-role
context and application developer-role context.
- Uses pending response input items so additional context can be
combined with normal user input without treating it as prompt text.
- Adds integration coverage for start/steer flow, role routing,
dedupe/reset behavior, deletion/re-add behavior, hook-blocked input
behavior, empty context-only steer rejection, external-fragment marker
matching, and truncation.

jif-oaiandGitHub 9f47e19b21 test: clean up apply_patch allow-session artifact (#24611)
## Why

The
`approving_apply_patch_for_session_skips_future_prompts_for_same_file`
integration test writes `apply_patch_allow_session.txt` under the
process cwd while exercising outside-workspace patch approval behavior.
With `just test` now being the normal validation path, that file can be
left behind in the checkout when the test runs or fails, creating
confusing untracked state.

## What changed

- Registers the resolved `apply_patch_allow_session.txt` path with
`tempfile::TempPath` before the test removes and recreates it through
`apply_patch`.
- Preserves the existing outside-workspace path shape so the approval
behavior under test does not change.
- Lets `TempPath` remove the generated file when the test exits,
including panic paths.

## Verification

- `just test -p codex-core --test all

jif-oaiandGitHub 05b8ce4354 chore: namespace v1 sub-agent tools (#23475)
## Why

The v1 sub-agent tools are a single tool family, but they were exposed
as separate flat function tools. This makes the model-visible surface
less clearly grouped and leaves the legacy names in the same flat
namespace as newer agent tooling.

## What

- Wraps the v1 `spawn_agent`, `send_input`, `resume_agent`,
`wait_agent`, and `close_agent` specs in the `multi_agent_v1` namespace.
- Registers the corresponding handlers with namespaced runtime tool
names.
- Updates tool-planning, deferred tool search, and sub-agent
notification tests to assert the namespace shape and child `spawn_agent`
lookup.

## Verification

- Updated `codex-core` coverage for the v1 multi-agent tool plan,
deferred tool search output, and sub-agent tool descriptions.

starr-openaiandGitHub 8736e32657 tests: avoid ambient temp sandbox roots (#22576)
## Why
Some sandboxed integration tests enabled both ambient temp roots
(`TMPDIR` and literal `/tmp`) even though they were not testing
temp-root behavior. On Linux bwrap, making `/tmp` writable causes
protected metadata mount targets such as `/tmp/.git`, `/tmp/.agents`,
and `/tmp/.codex` to be synthesized. If a run is interrupted, those
top-level markers can be left behind and contaminate later tests.

## What changed
For the incidental integration tests that do not need ambient temp-root
access, set `exclude_tmpdir_env_var` and `exclude_slash_tmp` to `true`.
Dedicated protected-metadata coverage remains in the lower-level sandbox
tests that use isolated temp roots.

## Verification
Focused remote devbox repros passed with a watcher polling `/tmp/.git`,
`/tmp/.agents`, and `/tmp/.codex`; no leaked markers were observed.

e783dab44c fix(exec-policy) use is_known_safe_command less (#20305)
## Summary
Restricts behavior of `is_known_safe_command` only to modes where it is
explicitly part of the documented behavior:
- when `environment_lacks_sandbox_protections`
- in `AskForApproval::UnlessTrusted`

Notably, as a result of this, escalations for commands that pass
`is_known_safe_commands` are no longer auto-approved in
AskForApproval::OnRequest or AskForApproval::Granular.

## Testing
- [x] Updated unit tests
- [x] Updated approvals scenario tests.

pakrym-oaiandGitHub e783341b70 [codex] Delete function-style apply_patch (#21651)
## Why

`apply_patch` is now a freeform/custom tool. Keeping the old
JSON/function-style registration and parsing path left another way for
models and tests to invoke `apply_patch`, which made the tool surface
harder to reason about.

## What changed

- Removed the `ApplyPatchToolType::Function` variant, JSON `apply_patch`
spec, and handler support for function payloads.
- Kept `apply_patch_tool_type = freeform` as the supported model
metadata path, including Bedrock catalog metadata.
- Migrated `apply_patch` tests and SSE fixtures to custom/freeform tool
calls.

a98623511b feat: add session_id (#20437)
## Summary

Related to
https://openai.slack.com/archives/C095U48JNL9/p1777537279707449
TLDR:
We update the meaning of session ids and thread ids:
* thread_id stays as now
* session_id become a shared id between every thread under a /root
thread (i.e. every sub-agent share the same session id)

This PR introduces an explicit `SessionId` and threads it through the
protocol/client boundary so `session_id` and `thread_id` can diverge
when they need to, while preserving compatibility for older serialized
`session_configured` events.

af089fb21d fix(exec_policy) heredoc parsing file_redirect (#20113)
## Summary
Fixes a regression introduced in #10941 so that heredocs do not permit
file redirects to be approved by rules, and adds scenario tests to cover
this behavior.


Previously, heredoc command parsing would allow redirects and
environment variables:
```bash
# commands_for_exec_policy() would parse this via parse_shell_lc_single_command_prefix
PATH=/tmp/bad:$PATH cat <<'EOF' > /tmp/bad/hello.txt
hello
EOF
```
This conflicts with the Codex Rules documentation; heredoc parsing logic
should abide by the same strictness of parsing.


## Tests
- [x] Updated unit tests accordingly
- [x] Added scenario tests for these cases

Michael BolinandGitHub 026df712cc core tests: migrate zsh-fork permissions to profiles (#20034)
## Summary
- Updates the zsh-fork test helper to configure `PermissionProfile`
directly instead of constructing a legacy `SandboxPolicy`.
- Sends permission-profile-backed turns from the skill approval zsh-fork
tests so the runtime and request path exercise the canonical permissions
model.
- Leaves the broader approvals suite on legacy policies for now, except
for the zsh-fork test that shares this helper.

## Verification
- `cargo check -p codex-core --tests`
- `just fmt`

Michael BolinandGitHub 9e26613657 permissions: add built-in default profiles (#19900)
## Why

The migration away from `SandboxPolicy` needs new configs to start from
permissions profiles instead of deriving profiles from legacy sandbox
modes. Existing users can have empty `config.toml` files, and we should
not rewrite user-owned config files that may live in shared
repositories.

This PR introduces built-in profile names so an empty config can resolve
to a canonical `PermissionProfile`, while explicit named `[permissions]`
profiles still behave predictably.

## What changed

- Adds built-in `default_permissions` profile names:
  - `:read-only` maps to `PermissionProfile::read_only()`.
- `:workspace` maps to the workspace-write profile, including
project-root metadata carveouts.
- `:danger-no-sandbox` maps to `PermissionProfile::Disabled`, preserving
the distinction between no sandbox and a broad managed sandbox.
- Reserves the `:` prefix for built-in profiles so user-defined
`[permissions]` profiles cannot collide with future built-ins.
- Allows `default_permissions` to reference a built-in profile without
requiring a `[permissions]` table.
- Makes an otherwise empty config choose a built-in profile by
trust/platform context: trusted or untrusted project roots use
`:workspace` when the platform supports that sandbox, while roots
without a trust decision use `:read-only`.
- Keeps legacy `sandbox_mode` configs on the legacy path, and still
rejects user-defined `[permissions]` profiles that omit
`default_permissions` so we do not silently guess among custom profiles.
- Preserves compatibility behavior for implicit defaults: bare
`network.enabled = true` allows runtime network without starting the
managed proxy, explicit profile proxy policy still starts the proxy, and
implicit workspace/add-dir roots keep legacy metadata carveouts.

## Verification

- `cargo test -p codex-core builtin --lib`
- `cargo test -p codex-core profile_network_proxy_config`
- `cargo test -p codex-core
implicit_builtin_workspace_profile_preserves_add_dir_metadata_carveouts`
- `cargo test -p codex-core
permissions_profiles_network_enabled_allows_runtime_network_without_proxy`
- `cargo test -p codex-core
permissions_profiles_proxy_policy_starts_managed_network_proxy`

## Documentation

Public Codex config docs should mention these built-in names when the
`[permissions]` config format is ready to document as stable.

pakrym-oaiandGitHub 9c3abcd46c [codex] Move config loading into codex-config (#19487)
## Why

Config loading had become split across crates: `codex-config` owned the
config types and merge logic, while `codex-core` still owned the loader
that assembled the layer stack. This change consolidates that
responsibility in `codex-config`, so the crate that defines config
behavior also owns how configs are discovered and loaded.

To make that move possible without reintroducing the old dependency
cycle, the shell-environment policy types and helpers that
`codex-exec-server` needs now live in `codex-protocol` instead of
flowing through `codex-config`.

This also makes the migrated loader tests more deterministic on machines
that already have managed or system Codex config installed by letting
tests override the system config and requirements paths instead of
reading the host's `/etc/codex`.

## What Changed

- moved the config loader implementation from `codex-core` into
`codex-config::loader` and deleted the old `core::config_loader` module
instead of leaving a compatibility shim
- moved shell-environment policy types and helpers into
`codex-protocol`, then updated `codex-exec-server` and other downstream
crates to import them from their new home
- updated downstream callers to use loader/config APIs from
`codex-config`
- added test-only loader overrides for system config and requirements
paths so loader-focused tests do not depend on host-managed config state
- cleaned up now-unused dependency entries and platform-specific cfgs
that were surfaced by post-push CI

## Testing

- `cargo test -p codex-config`
- `cargo test -p codex-core config_loader_tests::`
- `cargo test -p codex-protocol -p codex-exec-server -p
codex-cloud-requirements -p codex-rmcp-client --lib`
- `cargo test --lib -p codex-app-server-client -p codex-exec`
- `cargo test --no-run --lib -p codex-app-server`
- `cargo test -p codex-linux-sandbox --lib`
- `cargo shear`
- `just bazel-lock-check`

## Notes

- I did not chase unrelated full-suite failures outside the migrated
loader surface.
- `cargo test -p codex-core --lib` still hits unrelated proxy-sensitive
failures on this machine, and Windows CI still shows unrelated
long-running/timeouting test noise outside the loader migration itself.

Michael BolinandGitHub 4d7ce3447d permissions: make runtime config profile-backed (#19606)
## 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`

Dylan HurdandGitHub f5497f4d65 Split approval matrix test groups (#19454)
## Why

Recent `main` CI repeatedly timed out in:

- `codex-core::all suite::approvals::approval_matrix_covers_all_modes`

It failed in runs
[24909500958](https://github.com/openai/codex/actions/runs/24909500958),
[24908076251](https://github.com/openai/codex/actions/runs/24908076251),
[24906197645](https://github.com/openai/codex/actions/runs/24906197645),
[24905823212](https://github.com/openai/codex/actions/runs/24905823212),
[24903439629](https://github.com/openai/codex/actions/runs/24903439629),
[24903336028](https://github.com/openai/codex/actions/runs/24903336028),
and
[24898949647](https://github.com/openai/codex/actions/runs/24898949647).

The failure pattern was a 60s Linux remote timeout. Logs showed many
approval scenarios completing before the single matrix test timed out.

## Root Cause

`approval_matrix_covers_all_modes` packed every approval/sandbox/tool
scenario into one test case. That made the test vulnerable to normal CI
variance: one slow scenario or a slow process startup could push the
whole monolithic case past the 60s per-test timeout. It also hid which
part of the matrix was slow because the runner only reported the one
large matrix test.

## What Changed

- Keep the shared `scenarios()` table as the single source of approval
matrix coverage.
- Use one `#[test_case]` per `ScenarioGroup` to generate five async
Tokio tests: danger/full-access, read-only, workspace-write,
apply-patch, and unified-exec.
- Keep the group runner small and add per-scenario error context so a
failure still reports the specific scenario name.

## Why This Should Be Reliable

Each scenario group now has its own test harness timeout instead of
sharing one timeout window with the full matrix. That removes the long
sequential loop from a single test while keeping the implementation
compact and easy to scan.

The tests still run through the same scenario definitions and runner, so
this preserves coverage. `test-case` already composes with
`#[tokio::test]` in this crate and is already available for test code.

Michael BolinandGitHub 789f387982 permissions: remove legacy read-only access modes (#19449)
## Why

`ReadOnlyAccess` was a transitional legacy shape on `SandboxPolicy`:
`FullAccess` meant the historical read-only/workspace-write modes could
read the full filesystem, while `Restricted` tried to carry partial
readable roots. The partial-read model now belongs in
`FileSystemSandboxPolicy` and `PermissionProfile`, so keeping it on
`SandboxPolicy` makes every legacy projection reintroduce lossy
read-root bookkeeping and creates unnecessary noise in the rest of the
permissions migration.

This PR makes the legacy policy model narrower and explicit:
`SandboxPolicy::ReadOnly` and `SandboxPolicy::WorkspaceWrite` represent
the old full-read sandbox modes only. Split readable roots, deny-read
globs, and platform-default/minimal read behavior stay in the runtime
permissions model.

## What changed

- Removes `ReadOnlyAccess` from
`codex_protocol::protocol::SandboxPolicy`, including the generated
`access` and `readOnlyAccess` API fields.
- Updates legacy policy/profile conversions so restricted filesystem
reads are represented only by `FileSystemSandboxPolicy` /
`PermissionProfile` entries.
- Keeps app-server v2 compatible with legacy `fullAccess` read-access
payloads by accepting and ignoring that no-op shape, while rejecting
legacy `restricted` read-access payloads instead of silently widening
them to full-read legacy policies.
- Carries Windows sandbox platform-default read behavior with an
explicit override flag instead of depending on
`ReadOnlyAccess::Restricted`.
- Refreshes generated app-server schema/types and updates tests/docs for
the simplified legacy policy shape.

## Verification

- `cargo check -p codex-app-server-protocol --tests`
- `cargo check -p codex-windows-sandbox --tests`
- `cargo test -p codex-app-server-protocol sandbox_policy_`

Michael BolinandGitHub 040976b218 tests: isolate approval fixtures from host rules (#18288)
## Why

Several approval-focused tests were unintentionally sensitive to
host-level rule files. On machines with broader allowed command
prefixes, commonly allowed commands such as `/bin/date` could bypass the
approval path these tests were meant to exercise, making the fixtures
depend on the developer or CI host configuration.

## What changed

- Pins the approval matrix fixture to the explicit user reviewer so it
does not inherit a host reviewer.
- Changes OTel approval fixtures to request `/usr/bin/touch
codex-otel-approval-test`, avoiding a command that may be pre-approved
by local rules.
- Clears the config layer stack for the permissions-message assertion
that needs to compare only the permissions text under test.

Michael BolinandGitHub f90cc0ee64 tui: carry permission profiles on user turns (#18285)
## Why

Per-turn permission overrides should use the same canonical profile
abstraction as session configuration. That lets TUI submissions preserve
exact configured permissions without round-tripping through legacy
sandbox fields.

## What changed

This adds `permission_profile` to user-turn operations, threads it
through TUI/app-server submission paths, fills the new field in existing
test fixtures, and adds coverage that composer submission includes the
configured profile.

## Verification

- `cargo test -p codex-tui permissions -- --nocapture`
- `cargo test -p codex-core --test all permissions_messages --

Felipe CouryandGitHub 09ebc34f17 fix(core): emit hooks for apply_patch edits (#18391)
Fixes https://github.com/openai/codex/issues/16732.

## Why

`apply_patch` is Codex's primary file edit path, but it was not emitting
`PreToolUse` or `PostToolUse` hook events. That meant hook-based policy,
auditing, and write coordination could observe shell commands while
missing the actual file mutation performed by `apply_patch`.

The issue also exposed that the hook runtime serialized command hook
payloads with `tool_name: "Bash"` unconditionally. Even if `apply_patch`
supplied hook payloads, hooks would either fail to match it directly or
receive misleading stdin that identified the edit as a Bash tool call.

## What Changed

- Added `PreToolUse` and `PostToolUse` payload support to
`ApplyPatchHandler`.
- Exposed the raw patch body as `tool_input.command` for both
JSON/function and freeform `apply_patch` calls.
- Taught tool hook payloads to carry a handler-supplied hook-facing
`tool_name`.
- Preserved existing shell compatibility by continuing to emit `Bash`
for shell-like tools.
- Serialized the selected hook `tool_name` into hook stdin instead of
hardcoding `Bash`.
- Relaxed the generated hook command input schema so `tool_name` can
represent tools other than `Bash`.

## Verification

Added focused handler coverage for:

- JSON/function `apply_patch` calls producing a `PreToolUse` payload.
- Freeform `apply_patch` calls producing a `PreToolUse` payload.
- Successful `apply_patch` output producing a `PostToolUse` payload.
- Shell and `exec_command` handlers continuing to expose `Bash`.

Added end-to-end hook coverage for:

- A `PreToolUse` hook matching `^apply_patch$` blocking the patch before
the target file is created.
- A `PostToolUse` hook matching `^apply_patch$` receiving the patch
input and tool response, then adding context to the follow-up model
request.
- Non-participating tools such as the plan tool continuing not to emit
`PreToolUse`/`PostToolUse` hook events.

Also validated manually with a live `codex exec` smoke test using an
isolated temp workspace and temp `CODEX_HOME`. The smoke test confirmed
that a real `apply_patch` edit emits `PreToolUse`/`PostToolUse` with
`tool_name: "apply_patch"`, a shell command still emits `tool_name:
"Bash"`, and a denying `PreToolUse` hook prevents the blocked patch file
from being created.

Michael BolinandGitHub dcec516313 protocol: canonicalize file system permissions (#18274)
## Why

`PermissionProfile` needs stable, canonical file-system semantics before
it can become the primary runtime permissions abstraction. Without a
canonical form, callers have to keep re-deriving legacy sandbox maps and
profile comparisons remain lossy or order-dependent.

## What changed

This adds canonicalization helpers for `FileSystemPermissions` and
`PermissionProfile`, expands special paths into explicit sandbox
entries, and updates permission request/conversion paths to consume
those canonical entries. It also tightens the legacy bridge so root-wide
write profiles with narrower carveouts are not silently projected as
full-disk legacy access.

Michael BolinandGitHub 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.

viyatb-oaiandGitHub ec089fd22a fix(sandbox): fix bwrap lookup for multi-entry PATH (#15973)
## Summary
- split the joined `PATH` before running system `bwrap` lookup
- keep the existing workspace-local `bwrap` skip behavior intact
- add regression tests that exercise real multi-entry search paths

## Why
The PATH-based lookup added in #15791 still wrapped the raw `PATH`
environment value as a single `PathBuf` before passing it through
`join_paths()`. On Unix, a normal multi-entry `PATH` contains `:`, so
that wrapper path is invalid as one path element and the lookup returns
`None`.

That made Codex behave as if no system `bwrap` was installed even when
`bwrap` was available on `PATH`, which is what users in #15340 were
still hitting on `0.117.0-alpha.25`.

## Impact
System `bwrap` discovery now works with normal multi-entry `PATH` values
instead of silently falling back to the vendored binary.

Fixes #15340.

84f4e7b39d fix(subagents) share execpolicy by default (#13702)
## Summary
If a subagent requests approval, and the user persists that approval to
the execpolicy, it should (by default) propagate. We'll need to rethink
this a bit in light of coming Permissions changes, though I think this
is closer to the end state that we'd want, which is that execpolicy
changes to one permissions profile should be synced across threads.

4d9d4b7b0f Stabilize approval matrix write-file command (#14968)
## What is flaky
The approval-matrix `WriteFile` scenario is flaky. It sometimes fails in
CI even though the approval logic is unchanged, because the test
delegates the file write and readback to shell parsing instead of
deterministic file I/O.

## Why it was flaky
The test generated a command shaped like `printf ... > file && cat
file`. That means the scenario depended on shell quoting, redirection,
newline handling, and encoding behavior in addition to the approval
system it was actually trying to validate. If the shell interpreted the
payload differently, the test would report an approval failure even
though the product logic was fine.

That also made failures hard to diagnose, because the test did not log
the exact generated command or the parsed result payload.

## How this PR fixes it
This PR replaces the shell-redirection path with a deterministic
`python3 -c` script that writes the file with `Path.write_text(...,
encoding='utf-8')` and then reads it back with the same UTF-8 path. It
also logs the generated command and the resulting exit code/stdout for
the approval scenario so any future failure is directly attributable.

## Why this fix fixes the flakiness
The scenario no longer depends on shell parsing and redirection
semantics. The file contents are produced and read through explicit
UTF-8 file I/O, so the approval test is measuring approval behavior
instead of shell behavior. The added diagnostics mean a future failure
will show the exact command/result pair instead of looking like a
generic intermittent mismatch.

Ahmed IbrahimandGitHub c7e847aaeb Add diagnostics for read_only_unless_trusted timeout flake (#14518)
## Summary
- add targeted diagnostic logging for the
read_only_unless_trusted_requires_approval scenarios in
approval_matrix_covers_all_modes
- add a scoped timeout buffer only for ro_unless_trusted write-file
scenarios: 1000ms -> 2000ms
- keep all other write-file scenarios at 1000ms

## Why
The last two main failures were both in codex-core::all
suite::approvals::approval_matrix_covers_all_modes with exit_code=124 in
the same scenario. This points to execution-time jitter in CI rather
than a semantic approval-policy mismatch.

## Notes
- This does not introduce any >5s timeout and does not
disable/quarantine tests.
- The timeout increase is tightly scoped to the single flaky path and
keeps the matrix deterministic under CI scheduling variance.

Michael BolinandGitHub f82678b2a4 config: add initial support for the new permission profile config language in config.toml (#13434)
## Why

`SandboxPolicy` currently mixes together three separate concerns:

- parsing layered config from `config.toml`
- representing filesystem sandbox state
- carrying basic network policy alongside filesystem choices

That makes the existing config awkward to extend and blocks the new TOML
proposal where `[permissions]` becomes a table of named permission
profiles selected by `default_permissions`. (The idea is that if
`default_permissions` is not specified, we assume the user is opting
into the "traditional" way to configure the sandbox.)

This PR adds the config-side plumbing for those profiles while still
projecting back to the legacy `SandboxPolicy` shape that the current
macOS and Linux sandbox backends consume.

It also tightens the filesystem profile model so scoped entries only
exist for `:project_roots`, and so nested keys must stay within a
project root instead of using `.` or `..` traversal.

This drops support for the short-lived `[permissions.network]` in
`config.toml` because now that would be interpreted as a profile named
`network` within `[permissions]`.

## What Changed

- added `PermissionsToml`, `PermissionProfileToml`,
`FilesystemPermissionsToml`, and `FilesystemPermissionToml` so config
can parse named profiles under `[permissions.<profile>.filesystem]`
- added top-level `default_permissions` selection, validation for
missing or unknown profiles, and compilation from a named profile into
split `FileSystemSandboxPolicy` and `NetworkSandboxPolicy` values
- taught config loading to choose between the legacy `sandbox_mode` path
and the profile-based path without breaking legacy users
- introduced `codex-protocol::permissions` for the split filesystem and
network sandbox types, and stored those alongside the legacy projected
`sandbox_policy` in runtime `Permissions`
- modeled `FileSystemSpecialPath` so only `ProjectRoots` can carry a
nested `subpath`, matching the intended config syntax instead of
allowing invalid states for other special paths
- restricted scoped filesystem maps to `:project_roots`, with validation
that nested entries are non-empty descendant paths and cannot use `.` or
`..` to escape the project root
- kept existing runtime consumers working by projecting
`FileSystemSandboxPolicy` back into `SandboxPolicy`, with an explicit
error for profiles that request writes outside the workspace root
- loaded proxy settings from top-level `[network]`
- regenerated `core/config.schema.json`

## Verification

- added config coverage for profile deserialization,
`default_permissions` selection, top-level `[network]` loading, network
enablement, rejection of writes outside the workspace root, rejection of
nested entries for non-`:project_roots` special paths, and rejection of
parent-directory traversal in `:project_roots` maps
- added protocol coverage for the legacy bridge rejecting non-workspace
writes

## Docs

- update the Codex config docs on developers.openai.com/codex to
document named `[permissions.<profile>]` entries, `default_permissions`,
scoped `:project_roots` syntax, the descendant-path restriction for
nested `:project_roots` entries, and top-level `[network]` proxy
configuration

cb1a182bbe Clarify sandbox permission override helper semantics (#13703)
## Summary
Today `SandboxPermissions::requires_additional_permissions()` does not
actually mean "is `WithAdditionalPermissions`". It returns `true` for
any non-default sandbox override, including `RequireEscalated`. That
broad behavior is relied on in multiple `main` callsites.

The naming is security-sensitive because `SandboxPermissions` is used on
shell-like tool calls to tell the executor how a single command should
relate to the turn sandbox:
- `UseDefault`: run with the turn sandbox unchanged
- `RequireEscalated`: request execution outside the sandbox
- `WithAdditionalPermissions`: stay sandboxed but widen permissions for
that command only

## Problem
The old helper name reads as if it only applies to the
`WithAdditionalPermissions` variant. In practice it means "this command
requested any explicit sandbox override."

That ambiguity made it easy to read production checks incorrectly and
made the guardian change look like a standalone `main` fix when it is
not.

On `main` today:
- `shell` and `unified_exec` intentionally reject any explicit
`sandbox_permissions` request unless approval policy is `OnRequest`
- `exec_policy` intentionally treats any explicit sandbox override as
prompt-worthy in restricted sandboxes
- tests intentionally serialize both `RequireEscalated` and
`WithAdditionalPermissions` as explicit sandbox override requests

So changing those callsites from the broad helper to a narrow
`WithAdditionalPermissions` check would be a behavior change, not a pure
cleanup.

## What This PR Does
- documents `SandboxPermissions` as a per-command sandbox override, not
a generic permissions bag
- adds `requests_sandbox_override()` for the broad meaning: anything
except `UseDefault`
- adds `uses_additional_permissions()` for the narrow meaning: only
`WithAdditionalPermissions`
- keeps `requires_additional_permissions()` as a compatibility alias to
the broad meaning for now
- updates the current broad callsites to use the accurately named broad
helper
- adds unit coverage that locks in the semantics of all three helpers

## What This PR Does Not Do
This PR does not change runtime behavior. That is intentional.

Michael BolinandGitHub bfff0c729f config: enforce enterprise feature requirements (#13388)
## Why

Enterprises can already constrain approvals, sandboxing, and web search
through `requirements.toml` and MDM, but feature flags were still only
configurable as managed defaults. That meant an enterprise could suggest
feature values, but it could not actually pin them.

This change closes that gap and makes enterprise feature requirements
behave like the other constrained settings. The effective feature set
now stays consistent with enterprise requirements during config load,
when config writes are validated, and when runtime code mutates feature
flags later in the session.

It also tightens the runtime API for managed features. `ManagedFeatures`
now follows the same constraint-oriented shape as `Constrained<T>`
instead of exposing panic-prone mutation helpers, and production code
can no longer construct it through an unconstrained `From<Features>`
path.

The PR also hardens the `compact_resume_fork` integration coverage on
Windows. After the feature-management changes,
`compact_resume_after_second_compaction_preserves_history` was
overflowing the libtest/Tokio thread stacks on Windows, so the test now
uses an explicit larger-stack harness as a pragmatic mitigation. That
may not be the ideal root-cause fix, and it merits a parallel
investigation into whether part of the async future chain should be
boxed to reduce stack pressure instead.

## What Changed

Enterprises can now pin feature values in `requirements.toml` with the
requirements-side `features` table:

```toml
[features]
personality = true
unified_exec = false
```

Only canonical feature keys are allowed in the requirements `features`
table; omitted keys remain unconstrained.

- Added a requirements-side pinned feature map to
`ConfigRequirementsToml`, threaded it through source-preserving
requirements merge and normalization in `codex-config`, and made the
TOML surface use `[features]` (while still accepting legacy
`[feature_requirements]` for compatibility).
- Exposed `featureRequirements` from `configRequirements/read`,
regenerated the JSON/TypeScript schema artifacts, and updated the
app-server README.
- Wrapped the effective feature set in `ManagedFeatures`, backed by
`ConstrainedWithSource<Features>`, and changed its API to mirror
`Constrained<T>`: `can_set(...)`, `set(...) -> ConstraintResult<()>`,
and result-returning `enable` / `disable` / `set_enabled` helpers.
- Removed the legacy-usage and bulk-map passthroughs from
`ManagedFeatures`; callers that need those behaviors now mutate a plain
`Features` value and reapply it through `set(...)`, so the constrained
wrapper remains the enforcement boundary.
- Removed the production loophole for constructing unconstrained
`ManagedFeatures`. Non-test code now creates it through the configured
feature-loading path, and `impl From<Features> for ManagedFeatures` is
restricted to `#[cfg(test)]`.
- Rejected legacy feature aliases in enterprise feature requirements,
and return a load error when a pinned combination cannot survive
dependency normalization.
- Validated config writes against enterprise feature requirements before
persisting changes, including explicit conflicting writes and
profile-specific feature states that normalize into invalid
combinations.
- Updated runtime and TUI feature-toggle paths to use the constrained
setter API and to persist or apply the effective post-constraint value
rather than the requested value.
- Updated the `core_test_support` Bazel target to include the bundled
core model-catalog fixtures in its runtime data, so helper code that
resolves `core/models.json` through runfiles works in remote Bazel test
environments.
- Renamed the core config test coverage to emphasize that effective
feature values are normalized at runtime, while conflicting persisted
config writes are rejected.
- Ran `compact_resume_after_second_compaction_preserves_history` inside
an explicit 8 MiB test thread and Tokio runtime worker stack, following
the existing larger-stack integration-test pattern, to keep the Windows
`compact_resume_fork` test slice from aborting while a parallel
investigation continues into whether some of the underlying async
futures should be boxed.

## Verification

- `cargo test -p codex-config`
- `cargo test -p codex-core feature_requirements_ -- --nocapture`
- `cargo test -p codex-core
load_requirements_toml_produces_expected_constraints -- --nocapture`
- `cargo test -p codex-core
compact_resume_after_second_compaction_preserves_history -- --nocapture`
- `cargo test -p codex-core compact_resume_fork -- --nocapture`
- Re-ran the built `codex-core` `tests/all` binary with
`RUST_MIN_STACK=262144` for
`compact_resume_after_second_compaction_preserves_history` to confirm
the explicit-stack harness fixes the deterministic low-stack repro.
- `cargo test -p codex-core`
- This still fails locally in unrelated integration areas that expect
the `codex` / `test_stdio_server` binaries or hit existing `search_tool`
wiremock mismatches.

## Docs

`developers.openai.com/codex` should document the requirements-side
`[features]` table for enterprise and MDM-managed configuration,
including that it only accepts canonical feature keys and that
conflicting config writes are rejected.

Michael BolinandGitHub 1a8d930267 core: adopt host_executable() rules in zsh-fork (#13046)
## Why

[#12964](https://github.com/openai/codex/pull/12964) added
`host_executable()` support to `codex-execpolicy`, but the zsh-fork
interception path in `unix_escalation.rs` was still evaluating commands
with the default exact-token matcher.

That meant an intercepted absolute executable such as `/usr/bin/git
status` could still miss basename rules like `prefix_rule(pattern =
["git", "status"])`, even when the policy also defined a matching
`host_executable(name = "git", ...)` entry.

This PR adopts the new matching behavior in the zsh-fork runtime only.
That keeps the rollout intentionally narrow: zsh-fork already requires
explicit user opt-in, so it is a safer first caller to exercise the new
`host_executable()` scheme before expanding it to other execpolicy call
sites.

It also brings zsh-fork back in line with the current `prefix_rule()`
execution model. Until prefix rules can carry their own permission
profiles, a matched `prefix_rule()` is expected to rerun the intercepted
command unsandboxed on `allow`, or after the user accepts `prompt`,
instead of merely continuing inside the inherited shell sandbox.

## What Changed

- added `evaluate_intercepted_exec_policy()` in
`core/src/tools/runtimes/shell/unix_escalation.rs` to centralize
execpolicy evaluation for intercepted commands
- switched intercepted direct execs in the zsh-fork path to
`check_multiple_with_options(...)` with `MatchOptions {
resolve_host_executables: true }`
- added `commands_for_intercepted_exec_policy()` so zsh-fork policy
evaluation works from intercepted `(program, argv)` data instead of
reconstructing a synthetic command before matching
- left shell-wrapper parsing intentionally disabled by default behind
`ENABLE_INTERCEPTED_EXEC_POLICY_SHELL_WRAPPER_PARSING`, so
path-sensitive matching relies on later direct exec interception rather
than shell-script parsing
- made matched `prefix_rule()` decisions rerun intercepted commands with
`EscalationExecution::Unsandboxed`, while unmatched-command fallback
keeps the existing sandbox-preserving behavior
- extracted the zsh-fork test harness into
`core/tests/common/zsh_fork.rs` so both the skill-focused and
approval-focused integration suites can exercise the same runtime setup
- limited this change to the intercepted zsh-fork path rather than
changing every execpolicy caller at once
- added runtime coverage in
`core/src/tools/runtimes/shell/unix_escalation_tests.rs` for allowed and
disallowed `host_executable()` mappings and the wrapper-parsing modes
- added integration coverage in `core/tests/suite/approvals.rs` to
verify a saved `prefix_rule(pattern=["touch"], decision="allow")` reruns
under zsh-fork outside a restrictive `WorkspaceWrite` sandbox

pakrym-oaiandGitHub 951a389654 Allow clients not to send summary as an option (#12950)
Summary is a required parameter on UserTurn. Ideally we'd like the core
to decide the appropriate summary level.

Make the summary optional and don't send it when not needed.

Dylan HurdandGitHub f6053fdfb3 feat(core) Introduce Feature::RequestPermissions (#11871)
## Summary
Introduces the initial implementation of Feature::RequestPermissions.
RequestPermissions allows the model to request that a command be run
inside the sandbox, with additional permissions, like writing to a
specific folder. Eventually this will include other rules as well, and
the ability to persist these permissions, but this PR is already quite
large - let's get the core flow working and go from there!

viyatb-oaiandGitHub c3048ff90a feat(core): persist network approvals in execpolicy (#12357)
## Summary
Persist network approval allow/deny decisions as `network_rule(...)`
entries in execpolicy (not proxy config)

It adds `network_rule` parsing + append support in `codex-execpolicy`,
including `decision="prompt"` (parse-only; not compiled into proxy
allow/deny lists)
- compile execpolicy network rules into proxy allow/deny lists and
update the live proxy state on approval
- preserve requirements execpolicy `network_rule(...)` entries when
merging with file-based execpolicy
- reject broad wildcard hosts (for example `*`) for persisted
`network_rule(...)`

Michael BolinandGitHub 1af2a37ada chore: remove codex-core public protocol/shell re-exports (#12432)
## Why

`codex-rs/core/src/lib.rs` re-exported a broad set of types and modules
from `codex-protocol` and `codex-shell-command`. That made it easy for
workspace crates to import those APIs through `codex-core`, which in
turn hides dependency edges and makes it harder to reduce compile-time
coupling over time.

This change removes those public re-exports so call sites must import
from the source crates directly. Even when a crate still depends on
`codex-core` today, this makes dependency boundaries explicit and
unblocks future work to drop `codex-core` dependencies where possible.

## What Changed

- Removed public re-exports from `codex-rs/core/src/lib.rs` for:
- `codex_protocol::protocol` and related protocol/model types (including
`InitialHistory`)
  - `codex_protocol::config_types` (`protocol_config_types`)
- `codex_shell_command::{bash, is_dangerous_command, is_safe_command,
parse_command, powershell}`
- Migrated workspace Rust call sites to import directly from:
  - `codex_protocol::protocol`
  - `codex_protocol::config_types`
  - `codex_protocol::models`
  - `codex_shell_command`
- Added explicit `Cargo.toml` dependencies (`codex-protocol` /
`codex-shell-command`) in crates that now import those crates directly.
- Kept `codex-core` internal modules compiling by using `pub(crate)`
aliases in `core/src/lib.rs` (internal-only, not part of the public
API).
- Updated the two utility crates that can already drop a `codex-core`
dependency edge entirely:
  - `codex-utils-approval-presets`
  - `codex-utils-cli`

## Verification

- `cargo test -p codex-utils-approval-presets`
- `cargo test -p codex-utils-cli`
- `cargo check --workspace --all-targets`
- `just clippy`
