## Summary
- detect remote exec-server sessions in the unified-exec runtime
- bypass the local shell-snapshot bootstrap only for those remote
sessions
- preserve existing local snapshot wrapping, PowerShell UTF-8 prefixing,
sandbox orchestration, and zsh-fork handling
## Why
The shell snapshot file is currently captured and stored next to Core.
If Core wraps a remote command with `. /path/to/local/snapshot`, the
process starts on the executor and tries to source a path from the
orchestrator filesystem. This keeps remote commands from receiving that
known-local path until shell snapshots are captured/restored on the
executor side.
## Validation
- `just fmt`
- `git diff --check`
- `cargo test -p codex-core --lib tools::runtimes::tests`

Problem: The statusline reported context as an “X% left” value, which
could be mistaken for quota, and context usage was included in the
default footer.
Solution: Render configured context status items as a filling context
meter, preserve `context-used` as a legacy alias while hiding it from
the setup menu, and remove context from the default statusline. It will
still be available as an opt-in option for users who want to see it.

/>
Add an exec-server env policy contract and send only the env overlay needed for runtime/sandbox transforms when Core starts remote unified-exec processes. Keep local process startup on the existing exact-env path, and share the shell-environment-policy builder from codex-config so the executor can apply the same inherit/filter/set/include rules against its own process environment.

## Summary
- keep pending steered input buffered until the active user prompt has
received a model response
- keep steering pending across auto-compact when there is real
model/tool continuation to resume
- allow queued steering to follow compaction immediately when the prior
model response was already final
- keep pending-input follow-up owned by `run_turn` instead of folding it
into `SamplingRequestResult`
- add regression coverage for mid-turn compaction, final-response
compaction, and compaction triggered before the next request after tool
output
## Root Cause
Steered input was drained at the top of every `run_turn` loop. After
auto-compaction, the loop continued and immediately appended any pending
steer after the compact summary, making a queued prompt look like the
newest task instead of letting the model first resume interrupted
model/tool work.
## Implementation Notes
This patch keeps the follow-up signals separated:
- `SamplingRequestResult.needs_follow_up` means model/tool continuation
is needed
- `sess.has_pending_input().await` means queued user steering exists
- `run_turn` computes the combined loop condition from those two signals
In `run_turn`:
```rust
let has_pending_input = sess.has_pending_input().await;
let needs_follow_up = model_needs_follow_up || has_pending_input;
```
After auto-compact we choose whether the next request may drain
steering:
```rust
can_drain_pending_input = !model_needs_follow_up;
```
That means:
- model/tool continuation + pending steer: compact -> resume once
without draining steer
- completed model answer + pending steer: compact -> drain/send the
steer immediately
- fresh user prompt: do not drain steering before the model has answered
the prompt once
The drain is still only `sess.get_pending_input().await`; when
`can_drain_pending_input` is false, core uses an empty local vec and
leaves the steer pending in session state.
## Validation
- PASS `cargo test -p codex-core --test all steered_user_input --
--nocapture`
- PASS `just fmt`
- PASS `git diff --check`
- NOT PASSING HERE `just fix -p codex-core` currently stops before
linting this change on an unrelated mainline test-build error:
`core/src/tools/spec_tests.rs` initializes `ToolsConfigParams` without
`image_generation_tool_auth_allowed`; this PR does not touch that file.
## Summary
- make realtime default to the v2 WebRTC path
- keep partial realtime config tables inheriting
`RealtimeConfig::default()`
## Validation
- CI found a stale config-test expectation; fixed in 974ba51bb3
- just fmt
- git diff --check

Addresses #17166
Problem: Source builds report version 0.0.0, so the TUI update path can
treat any released Codex version as upgradeable and show startup or
popup prompts.
Solution: Skip both TUI update prompt entry points when the running CLI
version is the source-build sentinel 0.0.0.
- Default realtime sessions to v2 and gpt-realtime-1.5 when no override
is configured.
- Add Op::RealtimeConversationStart integration coverage and keep
v1-specific tests explicit.

Problem: TUI desktop notifications are hard-gated on terminal focus, so
terminal/IDE hosts that want in-focus notifications cannot opt in.
Solution: Add a flat `[tui] notification_condition` setting (`unfocused`
by default, `always` opt-in), carry grouped TUI notification settings
through runtime config, apply method + condition together in the TUI,
and regenerate the config schema.
- Adds a core-owned realtime backend prompt template and preparation
path.
- Makes omitted realtime start prompts use the core default, while null
or empty prompts intentionally send empty instructions.
- Covers the core realtime path and app-server v2 path with integration
coverage.

Addresses #15943
Problem: Name-based resume could stop on a newer session_index entry
whose rollout was never persisted, shadowing an older saved thread with
the same name.
Solution: Materialize rollouts before indexing thread names and make
name lookup skip unresolved entries until it finds a persisted rollout.
Problem: Warp supports OSC 9 notifications, but the TUI's automatic
notification backend selection did not recognize its
`TERM_PROGRAM=WarpTerminal` environment value.
Solution: Treat `TERM_PROGRAM=WarpTerminal` as OSC 9-capable when
choosing the TUI desktop notification backend.
Currently, when a MCP server sends an elicitation to Codex running in
Full Access (`sandbox_policy: DangerFullAccess` + `approval_policy:
Never`), the elicitations are auto-cancelled.
This PR updates the automatic handling of MCP elicitations to be
consistent with other approvals in full-access, where they are
auto-approved. Because MCP elicitations may actually require user input,
this mechanism is limited to empty form elicitations.
## Changeset
- Add policy helper shared with existing MCP tool call approval
auto-approve
- Update `ElicitationRequestManager` to auto-approve elicitations in
full access when `can_auto_accept_elicitation` is true.
- Add tests

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.
Before this, the TUI was starting 2 app-server. One to check the login
status and one to actually start the session
This PR make only one app-server startup and defer the login check in
async, outside of the frame rendering path
