Switched arg0 runtime initialization from tokio::runtime::Runtime::new()
to an explicit multi-thread builder that sets the thread stack size to
16MiB.
This is only for Windows for now but we might need to do this for others
in the future. This is required because Codex becomes quite large and
Windows tends to consume stack a little bit faster (this is a known
thing even though everyone seems to have different theory on it)
## Summary
Based on our most recent [release
attempt](https://github.com/openai/codex/actions/runs/21980518940/job/63501739210)
we are not building the shell-tool-mcp job correctly. This one is
outside my expertise, but seems mostly reasonable.
## Testing
- [x] We really need dry runs of these
## Summary
When network requests were blocked, downstream code often had to infer
ask vs deny from free-form response text. That was brittle and led to
incorrect approval behavior.
This PR fixes the proxy side so blocked decisions are structured and
request metadata survives reliably.
## Description
- Blocked proxy responses now carry consistent structured policy
decision data.
- Request attempt metadata is preserved across proxy env paths
(including ALL_PROXY flows).
- Header stripping was tightened so we still remove unsafe forwarding
headers, but keep metadata needed for policy handling.
- Block messages were clarified (for example, allowlist miss vs explicit
deny).
- Added unified violation log entries so policy failures can be
inspected in one place.
- Added/updated tests for these behaviors.

## Summary
CI is broken on main because our CI toolchain is trying to run 1.93.1
while our rust toolchain is locked at 1.93.0. I'm sure it's likely safe
to upgrade, but let's keep things stable for now.
## Testing
- [x] CI should hopefully pass
## Summary
If the model suggests a bad rule, don't show it to the user. This does
not impact the parsing of existing rules, just the ones we show.
## Testing
- [x] Added unit tests
- [x] Ran locally
When `app/list` is called with `force_refetch=True`, we should seed the
results with what is already cached instead of starting from an empty
list. Otherwise when we send app/list/updated events, the client will
first see an empty list of accessible apps and then get the updated one.
We've had a few cases recently where someone enabled a feature flag for
a feature that's still under development or experimental. This test
should prevent this.
### Motivation
- Git subcommand matching was being classified as "dangerous" and caused
benign developer workflows (for example `git push --force-with-lease`)
to be blocked by the preflight policy.
- The change aligns behavior with the intent to reserve the dangerous
checklist for truly destructive shell ops (e.g. `rm -rf`) and avoid
surprising developer-facing blocks.
### Description
- Remove git-specific subcommand checks from
`is_dangerous_to_call_with_exec` in
`codex-rs/shell-command/src/command_safety/is_dangerous_command.rs`,
leaving only explicit `rm` and `sudo` passthrough checks.
- Deleted the git-specific helper logic that classified `reset`,
`branch`-delete, `push` (force/delete/refspec) and `clean --force` as
dangerous.
- Updated unit tests in the same file to assert that various `git
reset`/`git branch`/`git push`/`git clean` variants are no longer
classified as dangerous.
- Kept `find_git_subcommand` (used by safe-command classification)
intact so safe/unsafe parsing elsewhere remains functional.
### Testing
- Ran formatter with `just fmt` successfully.
- Ran unit tests with `cargo test -p codex-shell-command` and all tests
passed (`144 passed; 0 failed`).

## Summary
This PR delivers the first small, shippable step toward model-visible
state diffing by making
`TurnContextItem` more complete and standardizing how it is built.
Specifically, it:
- Adds persisted network context to `TurnContextItem`.
- Introduces a single canonical `TurnContext -> TurnContextItem`
conversion path.
- Routes existing rollout write sites through that canonical conversion
helper.
No context injection/diff behavior changes are included in this PR.
## Why this change
The design goal is to make `TurnContextItem` the canonical source of
truth for context-diff
decisions.
Before this PR:
- `TurnContextItem` did not include all TurnContext-derived environment
inputs needed for v1
completeness.
- Construction was duplicated at multiple write sites.
This PR addresses both with a minimal, reviewable change.
## Changes
### 1) Extend `TurnContextItem` with network state
- Added `TurnContextNetworkItem { allowed_domains, denied_domains }`.
- Added `network: Option<TurnContextNetworkItem>` to `TurnContextItem`.
- Kept backward compatibility by making the new field optional and
skipped when absent.
Files:
- `codex-rs/protocol/src/protocol.rs`
### 2) Canonical conversion helper
- Added `TurnContext::to_turn_context_item(collaboration_mode)` in core.
- Added internal helper to derive network fields from
`config_layer_stack.requirements().network`.
Files:
- `codex-rs/core/src/codex.rs`
### 3) Use canonical conversion at rollout write sites
- Replaced ad hoc `TurnContextItem { ... }` construction with
`to_turn_context_item(...)` in:
- sampling request path
- compaction path
Files:
- `codex-rs/core/src/codex.rs`
- `codex-rs/core/src/compact.rs`
### 4) Update fixtures/tests for new optional field
- Updated existing `TurnContextItem` literals in tests to include
`network: None`.
- Added protocol tests for:
- deserializing old payloads with no `network`
- serializing when `network` is present
Files:
- `codex-rs/core/tests/suite/resume_warning.rs`
- No replay/diff logic changes.
- Persisted rollout `TurnContextItem` now carries additional network
context when available.
- Older rollout lines without `network` remain readable.
Adds a new apps_mcp_gateway flag to route Apps MCP calls through
https://api.openai.com/v1/connectors/mcp/ when enabled, while keeping
legacy MCP routing as default.
Propagate client JSON-RPC errors for app-server request callbacks.
Previously a number of possible errors were collapsed to `channel
closed`. Now we should be able to see the underlying client error.
### Summary
This change stops masking client JSON-RPC error responses as generic
callback cancellation in app-server server->client request flows.
Previously, when the client responded with a JSON-RPC error, we removed
the callback entry but did not send anything to the waiting oneshot
receiver. Waiters then observed channel closure (for example, auth
refresh request canceled: channel closed), which hid the actual client
error.
Now, client JSON-RPC errors are forwarded through the callback channel
and handled explicitly by request consumers.
### User-visible behavior
- External auth refresh now surfaces real client JSON-RPC errors when
provided.
- True transport/callback-drop cases still report
canceled/channel-closed semantics.
### Example: client JSON-RPC error is now propagated (not masked as
"canceled")
When app-server asks the client to refresh ChatGPT auth tokens, it sends
a server->client JSON-RPC request like:
```json
{
"id": 42,
"method": "account/chatgptAuthTokens/refresh",
"params": {
"reason": "unauthorized",
"previousAccountId": "org-abc"
}
}
```
If the client cannot refresh and responds with a JSON-RPC error:
```
{
"id": 42,
"error": {
"code": -32000,
"message": "refresh failed",
"data": null
}
}
```
app-server now forwards that error through the callback path and
surfaces:
`auth refresh request failed: code=-32000 message=refresh failed`
Previously, this same case could be reported as:
`auth refresh request canceled: channel closed`
## Why
`review_start_with_detached_delivery_returns_new_thread_id` has been
failing on Windows CI. The failure mode is a process crash
(`tokio-runtime-worker` stack overflow) during detached review setup,
which causes EOF in the test harness.
This test is intended to validate detached review thread identity, not
shell snapshot behavior. We also still want detached review to avoid
unnecessary rollout-path rediscovery when the parent thread is already
loaded.
## What Changed
- Updated detached review startup in
`codex-rs/app-server/src/codex_message_processor.rs`:
- `start_detached_review` now receives the loaded parent thread.
- It prefers `parent_thread.rollout_path()`.
- It falls back to `find_thread_path_by_id_str(...)` only if the
in-memory path is unavailable.
- Hardened the review test fixture in
`codex-rs/app-server/tests/suite/v2/review.rs` by setting
`shell_snapshot = false` in test config, so this test no longer depends
on unrelated Windows PowerShell snapshot initialization.
## Verification
- `cargo test -p codex-app-server`
- Verified
`suite::v2::review::review_start_with_detached_delivery_returns_new_thread_id`
passes locally.
## Notes
- Related context: rollout-path lookup behavior changed in #10532.
## Why
`suite::v2::review::review_start_with_detached_delivery_returns_new_thread_id`
was failing on Windows CI due to an unrelated process crash during shell
snapshot initialization (`tokio-runtime-worker` stack overflow).
This review test suite validates review API behavior and should not
depend on shell snapshot behavior. Keeping shell snapshot enabled in
this fixture made the test flaky for reasons outside the scenario under
test.
## What Changed
- Updated the review suite test config in
`codex-rs/app-server/tests/suite/v2/review.rs` to set:
- `shell_snapshot = false`
This keeps the review tests focused on review behavior by disabling
shell snapshot initialization in this fixture.
## Verification
- `cargo test -p codex-app-server`
- Confirmed the previously failing Windows CI job for this test now
passes on this PR.
Adds an explicit requirement in AGENTS.md that any user-visible UI
change includes corresponding insta snapshot coverage and that snapshots
are reviewed/accepted in the PR.
Tests: N/A (docs only)
## Why
We currently carry multiple permission-related concepts directly on
`Config` for shell/unified-exec behavior (`approval_policy`,
`sandbox_policy`, `network`, `shell_environment_policy`,
`windows_sandbox_mode`).
Consolidating these into one in-memory struct makes permission handling
easier to reason about and sets up the next step: supporting named
permission profiles (`[permissions.PROFILE_NAME]`) without changing
behavior now.
This change is mostly mechanical: it updates existing callsites to go
through `config.permissions`, but it does not yet refactor those
callsites to take a single `Permissions` value in places where multiple
permission fields are still threaded separately.
This PR intentionally **does not** change the on-disk `config.toml`
format yet and keeps compatibility with legacy config keys.
## What Changed
- Introduced `Permissions` in `core/src/config/mod.rs`.
- Added `Config::permissions` and moved effective runtime permission
fields under it:
- `approval_policy`
- `sandbox_policy`
- `network`
- `shell_environment_policy`
- `windows_sandbox_mode`
- Updated config loading/building so these effective values are still
derived from the same existing config inputs and constraints.
- Updated Windows sandbox helpers/resolution to read/write via
`permissions`.
- Threaded the new field through all permission consumers across core
runtime, app-server, CLI/exec, TUI, and sandbox summary code.
- Updated affected tests to reference `config.permissions.*`.
- Renamed the struct/field from
`EffectivePermissions`/`effective_permissions` to
`Permissions`/`permissions` and aligned variable naming accordingly.
## Verification
- `just fix -p codex-core -p codex-tui -p codex-cli -p codex-app-server
-p codex-exec -p codex-utils-sandbox-summary`
- `cargo build -p codex-core -p codex-tui -p codex-cli -p
codex-app-server -p codex-exec -p codex-utils-sandbox-summary`
## Summary
In an effort to start simplifying our sandbox setup, we're announcing
this approval_policy as deprecated. In general, it performs worse than
`on-request`, and we're focusing on making fewer sandbox configurations
perform much better.
## Testing
- [x] Tested locally
- [x] Existing tests pass
There is an edge case where a directory is not readable by the sandbox.
In practice, we've seen very little of it, but it can happen so this
slash command unlocks users when it does.
Future idea is to make this a tool that the agent knows about so it can
be more integrated.
