Prepare sandbox env inside the sandbox transform result so core and exec-server do not have to mutate the request at their spawn boundaries.

Use /bin/sh for the PTY/stdin and write-denial probes so the tests do not depend on /usr/bin/python3 being usable on macOS Bazel runners.

Keep unified_exec request state as AbsolutePathBuf, but serialize the cwd to PathBuf when constructing exec-server ExecParams.
Co-authored-by: Codex <noreply@openai.com>
Validate exec-server cwd values into AbsolutePathBuf before sandbox transforms, pass the helper executable as Option<&Path>, and keep the Linux helper alias cfg-specific so non-Linux builds typecheck.
Co-authored-by: Codex <noreply@openai.com>
Keep the standalone exec-server binary capable of self-dispatching its Linux sandbox helper by materializing a private codex-linux-sandbox symlink at startup. This gives sandbox launch a real helper-looking executable path without depending on the top-level codex-arg0 dispatcher.

- preserve sandbox child environment variables from shared launch requests
- dispatch codex-exec-server through codex-arg0 so helper arg0 is executable
- send sandbox preference to remote servers and report the server-selected sandbox
Co-authored-by: Codex <noreply@openai.com>
Teach the standalone exec-server binary to run the Linux sandbox helper when it is re-execed with the codex-linux-sandbox argv0 alias. Point the exec-server sandbox transform at the current executable on Linux instead of requiring an env-provided helper path.

## Summary
- add the missing `image_generation_tool_auth_allowed` field to the new
tool registry plan test initializer
## Validation
- `just fmt`
- `cargo test -p codex-tools image_generation`
- `cargo test -p codex-tools --no-run`
When running with remote executor the cwd is the remote path. Today we
check for existence of a local directory on startup and attempt to load
config from it.
For remote executors don't do that.
## Summary
- add optional `sandboxPolicy` support to the app-server filesystem
request surface
- thread sandbox-aware filesystem options through app-server and
exec-server adapters
- enforce sandboxed read/write access in the filesystem abstraction with
focused local and remote coverage
## Validation
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-exec-server file_system`
- `cargo test -p codex-app-server suite::v2::fs`

**Disabling Image-Gen for Non-SIWC Codex Users**
We are only enabling image-gen feature for SIWC Codex users until there
comes a fix in ResponsesAPI to omit output from responses.completed, to
prevent the following issues:
1. websocket blows up due to heavier load (images) than before (text)
2. http parser streams through n^2 of n-base64 bytes (sum of base64s of
all images generated in turn) that causes long delays in
turn_completion.
## Description
This PR fixes `/debug-config` so it shows more of the active
requirements state, including reviewer requirements and managed feature
pins. This made it clear that legacy MDM config was setting
`approvals_reviewer = "guardian_subagent"` and that we were translating
that into a requirements constraint.
Also, translate `approvals_reviewer = "guardian_subagent"` (from legacy
managed_config.toml) to `allowed_approvals_reviewers: guardian_subagent,
user` instead of `allowed_approvals_reviewers: guardian_subagent`.
Example `/debug-config`:
```
Config layer stack (lowest precedence first):
1. system (/etc/codex/config.toml) (enabled)
2. user (/Users/owen/.codex/config.toml) (enabled)
3. project (/Users/owen/repos/codex/.codex/config.toml) (enabled)
4. legacy managed_config.toml (MDM) (enabled)
MDM value:
...
# Enable Guardian Mode
features.guardian_approval = true
approvals_reviewer = "guardian_subagent"
Requirements:
- allowed_approvals_reviewers: guardian_subagent, user (source: MDM managed_config.toml (legacy))
- features: apps=true, plugins=true (source: cloud requirements)
```
Before this PR, the `Requirements` section showed None.
## Summary
- Carry `AbsolutePathBuf` through tool cwd parsing/resolution instead of
resolving workdirs to raw `PathBuf`s.
- Type exec/sandbox request cwd fields as `AbsolutePathBuf` through
`ExecParams`, `ExecRequest`, `SandboxCommand`, and unified exec runtime
requests.
- Keep `PathBuf` conversions at external/event boundaries and update
existing tests/fixtures for the typed cwd.
## Validation
- `cargo check -p codex-core --tests`
- `cargo check -p codex-sandboxing --tests`
- `cargo test -p codex-sandboxing`
- `cargo test -p codex-core --lib tools::handlers::`
- `just fix -p codex-sandboxing`
- `just fix -p codex-core`
- `just fmt`
Full `codex-core` test suite was not run locally; per repo guidance I
kept local validation targeted.
Adds the `[realtime].transport = "webrtc"` TUI media path using a new
`codex-realtime-webrtc` crate, while leaving app-server as the
signaling/event source.\n\nLocal checks: fmt, diff-check, dependency
tree only; test signal should come from CI.

Addresses #16971
Problem: Disabled MCP servers were still queried for streamable HTTP
auth status during MCP inventory, so unreachable disabled entries could
add startup latency.
Solution: Return `Unsupported` immediately for disabled MCP server
configs before bearer token/OAuth status discovery.
Problem: Resuming the live TUI thread through `/resume` could
unsubscribe and reconnect the same app-server thread, leaving the UI
crashed or disconnected.
Solution: No-op `/resume` only when the selected thread is the currently
attached active thread; keep the normal resume path for
stale/displayed-only threads so recovery and reattach still work.
Addresses #3793
Problem: /status only reported project-level AGENTS files, so sessions
with a loaded global $CODEX_HOME/AGENTS.md still showed Agents.md as
<none>.
Solution: Track the global instructions file loaded during config
initialization and prepend that path to the /status Agents.md summary,
with coverage for AGENTS.md, AGENTS.override.md, and global-plus-project
ordering.
Allow multi_agent_v2 features to have its own temporary configuration
under `[features.multi_agent_v2]`
```
[features.multi_agent_v2]
enabled = true
usage_hint_enabled = false
usage_hint_text = "Custom delegation guidance."
hide_spawn_agent_metadata = true
```
Absent `usage_hint_text` means use the default hint.
```
[features]
multi_agent_v2 = true
```
still works as the boolean shorthand.
