This PR makes it possible to disable live web search via an enterprise
config even if the user is running in `--yolo` mode (though cached web
search will still be available). To do this, create
`/etc/codex/requirements.toml` as follows:
```toml
# "live" is not allowed; "disabled" is allowed even though not listed explicitly.
allowed_web_search_modes = ["cached"]
```
Or set `requirements_toml_base64` MDM as explained on
https://developers.openai.com/codex/security/#locations.
### Why
- Enforce admin/MDM/`requirements.toml` constraints on web-search
behavior, independent of user config and per-turn sandbox defaults.
- Ensure per-turn config resolution and review-mode overrides never
crash when constraints are present.
### What
- Add `allowed_web_search_modes` to requirements parsing and surface it
in app-server v2 `ConfigRequirements` (`allowedWebSearchModes`), with
fixtures updated.
- Define a requirements allowlist type (`WebSearchModeRequirement`) and
normalize semantics:
- `disabled` is always implicitly allowed (even if not listed).
- An empty list is treated as `["disabled"]`.
- Make `Config.web_search_mode` a `Constrained<WebSearchMode>` and apply
requirements via `ConstrainedWithSource<WebSearchMode>`.
- Update per-turn resolution (`resolve_web_search_mode_for_turn`) to:
- Prefer `Live → Cached → Disabled` when
`SandboxPolicy::DangerFullAccess` is active (subject to requirements),
unless the user preference is explicitly `Disabled`.
- Otherwise, honor the user’s preferred mode, falling back to an allowed
mode when necessary.
- Update TUI `/debug-config` and app-server mapping to display
normalized `allowed_web_search_modes` (including implicit `disabled`).
- Fix web-search integration tests to assert cached behavior under
`SandboxPolicy::ReadOnly` (since `DangerFullAccess` legitimately prefers
`live` when allowed).

## Summary
Stabilize v2 review integration tests by making them hermetic with
respect to model discovery.
`app-server` review tests were intermittently timing out in CI
(especially on Windows runners) because their test config allowed remote
model refresh. During `thread/start`, the test process could issue live
`/v1/models` requests, introducing external network latency and
nondeterministic timing before review flow assertions.
This change disables remote model fetching in the review test config
helper used by these tests.
Summary:
- Rename config table from network_proxy to network.
- Flatten allowed_domains, denied_domains, allow_unix_sockets, and
allow_local_binding onto NetworkProxySettings.
- Update runtime, state constraints, tests, and README to the new config
shape.
Example:
```toml
# This means that "live" is not allowed; "disabled" is allowed even though not listed explicitly.
allowed_web_search_modes = ["cached"]
```
### Why
- Support admin/MDM/requirements.toml constraints over web-search behavior, independent of user config or sandbox defaults.
- Ensure per-turn config resolution and review-mode overrides can never crash when constraints are present.
- Note that `allowed_web_search_modes = ["cached"]` denies `"live"`, even if `--yolo` is used. See `resolve_web_search_mode_for_turn()`.
### What
- Add `allowed_web_search_modes` to requirements parsing and app-server v2 `ConfigRequirements` (`allowedWebSearchModes`), with schema/TS fixture updates.
- Introduce TOML-only `WebSearchModeRequirement` for requirements allowlists; accept `disabled|cached|live`, and treat an empty list as `[disabled]`.
- Convert the allowlist to a `ConstrainedWithSource<Option<WebSearchMode>>`, always permitting `Disabled` while enforcing membership for other values.
- Make `Config.web_search_mode` a constrained field, update call sites/tests, and surface constraint violations via warnings/fallback.
- Extend TUI `/debug-config` output to display `allowed_web_search_modes`.
### Safety
- Avoid `expect()` on constrained `web_search_mode` mutation in session per-turn config and review-thread setup; warn and keep the constrained value instead.

```toml
# This means that "live" is not allowed; "disabled" is allowed even though not listed explicitly.

TLDR: use new message phase field emitted by preamble-supported models
to determine whether an AgentMessage is mid-turn commentary. if so,
restore the status indicator afterwards to indicate the turn has not
completed.
### Problem
`commit_tick` hides the status indicator while streaming assistant text.
For preamble-capable models, that text can be commentary mid-turn, so
hiding was correct during streaming but restore timing mattered:
- restoring too aggressively caused jitter/flashing
- not restoring caused indicator to stay hidden before subsequent work
(tool calls, web search, etc.)
### Fix
- Add optional `phase` to `AgentMessageItem` and propagate it from
`ResponseItem::Message`
- Keep indicator hidden during streamed commit ticks, restore only when:
- assistant item completes as `phase=commentary`, and
- stream queues are idle + task is still running.
- Treat `phase=None` as final-answer behavior (no restore) to keep
existing behavior for non-preamble models
### Tests
Add/update tests for:
- no idle-tick restore without commentary completion
- commentary completion restoring status before tool begin
- snapshot coverage for preamble/status behavior

This PR makes `Config.apps `experimental-only and fixes a TS schema
post-processing bug that removed needed imports. The bug happened
because import pruning only checked the inner type body after filtering,
not the full alias, so `JsonValue` got dropped from `Config.ts`. We now
prune against the full alias body and added a regression test for this
scenario.
## What changed
- In `codex-rs/core/src/skills/injection.rs`, we now honor explicit
`UserInput::Skill { name, path }` first, then fall back to text mentions
only when safe.
- In `codex-rs/tui/src/bottom_pane/chat_composer.rs`, mention selection
is now token-bound (selected mention is tied to the specific inserted
`$token`), and we snapshot bindings at submit time so selection is not
lost.
- In `codex-rs/tui/src/chatwidget.rs` and
`codex-rs/tui/src/bottom_pane/mod.rs`, submit/queue paths now consume
the submit-time mention snapshot (instead of rereading cleared composer
state).
- In `codex-rs/tui/src/mention_codec.rs` and
`codex-rs/tui/src/bottom_pane/chat_composer_history.rs`, history now
round-trips mention targets so resume restores the same selected
duplicate.
- In `codex-rs/tui/src/bottom_pane/skill_popup.rs` and
`codex-rs/tui/src/bottom_pane/chat_composer.rs`, duplicate labels are
normalized to `[Repo]` / `[App]`, app rows no longer show `Connected -`,
and description space is a bit wider.

## Before vs now
- Before: selecting a duplicate could still submit the default/repo
match, and resume could lose which duplicate was originally selected.
- Now: the exact selected target (skill path or app id) is preserved
through submit, queue/restore, and resume.
## Manual test
1. Build and run this branch locally:
- `cd /Users/daniels/code/codex/codex-rs`
- `cargo build -p codex-cli --bin codex`
- `./target/debug/codex`
2. Open mention picker with `$` and pick a duplicate entry (not the
first one).
3. Confirm duplicate UI:
- repo duplicate rows show `[Repo]`
- app duplicate rows show `[App]`
- app description does **not** start with `Connected -`
4. Submit the prompt, then press Up to restore draft and submit again.
Expected: it keeps the same selected duplicate target.
5. Use `/resume` to reopen the session and send again.
Expected: restored mention still resolves to the same duplicate target.
These fields had always been documented as experimental/unstable with
docstrings, but now let's actually use the `experimental` annotation to
be more explicit.

## Summary
When replaying compacted history (especially `replacement_history` from
remote compaction), we should not keep stale developer messages from
older session state. This PR trims developer-
role messages from compacted replacement history and reinjects fresh
developer instructions derived from current turn/session state.
This aligns compaction replay behavior with the intended "fresh
instructions after summary" model.
## Problem
Compaction replay had two paths:
- `Compacted { replacement_history: None }`: rebuilt with fresh initial
context
- `Compacted { replacement_history: Some(...) }`: previously used raw
replacement history as-is
The second path could carry stale developer instructions
(permissions/personality/collab-mode guidance) across session changes.
## What Changed
### 1) Added helper to refresh compacted developer instructions
- **File:** `codex-rs/core/src/compact.rs`
- **Function:** `refresh_compacted_developer_instructions(...)`
Behavior:
- remove all `ResponseItem::Message { role: "developer", .. }` from
compacted history
- append fresh developer messages from current
`build_initial_context(...)`
### 2) Applied helper in remote compaction flow
- **File:** `codex-rs/core/src/compact_remote.rs`
- After receiving compact endpoint output, refresh developer
instructions before replacing history and persisting
`replacement_history`.
### 3) Applied helper while reconstructing history from rollout
- **File:** `codex-rs/core/src/codex.rs`
- In `reconstruct_history_from_rollout(...)`, when processing
`Compacted` entries with `replacement_history`, refresh developer
instructions instead of directly replacing with raw history.
## Non-Goals / Follow-up
This PR does **not** address the existing first-turn-after-resume
double-injection behavior.
A follow-up PR will handle resume-time dedup/idempotence separately.
If you want, I can also give you a shorter “squash-merge friendly”
version of the description.

## Problem
The first user turn can pay websocket handshake latency even when a
session has already started. We want to reduce that initial delay while
preserving turn semantics and avoiding any prompt send during startup.
Reviewer feedback also called out duplicated connect/setup paths and
unnecessary preconnect state complexity.
## Mental model
`ModelClient` owns session-scoped transport state. During session
startup, it can opportunistically warm one websocket handshake slot. A
turn-scoped `ModelClientSession` adopts that slot once if available,
restores captured sticky turn-state, and otherwise opens a websocket
through the same shared connect path.
If startup preconnect is still in flight, first turn setup awaits that
task and treats it as the first connection attempt for the turn.
Preconnect is handshake-only. The first `response.create` is still sent
only when a turn starts.
## Non-goals
This change does not make preconnect required for correctness and does
not change prompt/turn payload semantics. It also does not expand
fallback behavior beyond clearing preconnect state when fallback
activates.
## Tradeoffs
The implementation prioritizes simpler ownership and shared connection
code over header-match gating for reuse. The single-slot cache keeps
lifecycle straightforward but only benefits the immediate next turn.
Awaiting in-flight preconnect has the same app-level connect-timeout
semantics as existing websocket connect behavior (no new timeout class
introduced by this PR).
## Architecture
`core/src/client.rs`:
- Added session-level preconnect lifecycle state (`Idle` / `InFlight` /
`Ready`) carrying one warmed websocket plus optional captured
turn-state.
- Added `pre_establish_connection()` startup warmup and `preconnect()`
handshake-only setup.
- Deduped auth/provider resolution into `current_client_setup()` and
websocket handshake wiring into `connect_websocket()` /
`build_websocket_headers()`.
- Updated turn websocket path to adopt preconnect first, await in-flight
preconnect when present, then create a new websocket only when needed.
- Ensured fallback activation clears warmed preconnect state.
- Added documentation for lifecycle, ownership, sticky-routing
invariants, and timeout semantics.
`core/src/codex.rs`:
- Session startup invokes `model_client.pre_establish_connection(...)`.
- Turn metadata resolution uses the shared timeout helper.
`core/src/turn_metadata.rs`:
- Centralized shared timeout helper used by both turn-time metadata
resolution and startup preconnect metadata building.
`core/tests/common/responses.rs` + websocket test suites:
- Added deterministic handshake waiting helper (`wait_for_handshakes`)
with bounded polling.
- Added startup preconnect and in-flight preconnect reuse coverage.
- Fallback expectations now assert exactly two websocket attempts in
covered scenarios (startup preconnect + turn attempt before fallback
sticks).
## Observability
Preconnect remains best-effort and non-fatal. Existing
websocket/fallback telemetry remains in place, and debug logs now make
preconnect-await behavior and preconnect failures easier to reason
about.
## Tests
Validated with:
1. `just fmt`
2. `cargo test -p codex-core websocket_preconnect -- --nocapture`
3. `cargo test -p codex-core websocket_fallback -- --nocapture`
4. `cargo test -p codex-core
websocket_first_turn_waits_for_inflight_preconnect -- --nocapture`
## Summary
Add explicit, model-visible network policy decision metadata to blocked
proxy responses/errors.
Introduces a standardized prefix line: `CODEX_NETWORK_POLICY_DECISION
{json}`
and wires it through blocked paths for:
- HTTP requests
- HTTPS CONNECT
- SOCKS5 TCP/UDP denials
## Why
The model should see *why* a request was blocked
(reason/source/protocol/host/port) so it can choose the correct next
action.
## Notes
- This PR is intentionally independent of config-layering/network-rule
runtime integration.
- Focus is blocked decision surface only.
