## Why
`chatwidget.rs` is still carrying too many unrelated responsibilities in
one file. #22269 started a five-phase cleanup to move coherent behavior
domains into focused modules while keeping `chatwidget.rs` as the
composition layer. #22407 completed phase 2 by extracting input and
submission flow, and #22433 completed phase 3 by extracting protocol,
replay, streaming, and tool lifecycle handling.
This PR is phase 4. It keeps moving high-churn UI coordination out of
the central widget by extracting settings, popups, and status surfaces
without changing the visible behavior those flows already provide. This
is once again a mechanical movement of existing functions. No functional
changes.
## What Changed
- Added focused modules for runtime settings/model coordination,
model/reasoning/collaboration popups,
settings/personality/theme/audio/experimental popups, permission
prompts, status setup/output controls, and Windows sandbox prompt flows.
- Moved the remaining rate-limit nudge/status helpers and connectors
popup/loading/update helpers into their existing focused modules.
- Preserved the existing picker flows, approval behavior, status/title
setup previews, rate-limit notices, and connectors/app list behavior
while shrinking `chatwidget.rs` back toward orchestration.
- Left `codex-rs/tui/src/chatwidget.rs` as the registration and
composition surface for these extracted behaviors.
## Cleanup Phases
The five-phase cleanup plan from #22269 is:
1. Phase 1: mechanical helper and state moves. Completed in #22269.
2. Phase 2: extract input and submission flow, including queued user
messages, shell prompt submission, pending steer restoration, and thread
input snapshot/restore behavior. Completed in #22407.
3. Phase 3: extract protocol, replay, streaming, and tool lifecycle
handling, while preserving active-cell grouping, transcript
invalidation, interrupt deferral, and final-message separator behavior.
Completed in #22433.
4. Phase 4: extract settings, popups, and status surfaces, including
model/reasoning/collaboration/personality popups, permission prompts,
rate-limit UI, and connectors helpers. This PR.
5. Phase 5: clean up the remaining constructor and orchestration code
once the larger behavior domains have moved out, leaving `chatwidget.rs`
as the composition layer.
## Verification

- `cargo test -p codex-tui chatwidget::tests::popups_and_settings`
- `cargo test -p codex-tui chatwidget::tests::status_and_layout`
`cargo test -p codex-tui` also compiles and begins running, but aborts
in the unchanged app-side test
`app::tests::discard_side_thread_keeps_local_state_when_server_close_fails`
with a reproducible stack overflow.
## Why
`TurnContext::cwd` and `TurnContext::resolve_path` are being phased out
in favor of using the selected turn environment cwd directly.
Deprecating both APIs makes any new direct dependency visible while
preserving the existing migration path for current callers.
## What Changed
- Marked `TurnContext::cwd` and `TurnContext::resolve_path` as
deprecated with guidance to use the selected turn environment cwd
instead.
- Added exact `#[allow(deprecated)]` suppressions at each existing
direct usage site, including tests, rather than adding crate-wide
suppression.
- Kept the change behavior-preserving: current cwd reads, writes, and
path resolution continue to use the same values.

Regular slack flows seem to work, also curling these endpoints with the
correct SKU returns the right apps
## Why
`code_mode_only` filters code-mode nested tools out of the top-level
tool list. For multi-agent v2, we need a rollout shape where the
collaboration tools remain callable as normal model tools without also
being embedded into the code-mode `exec` tool declaration.
Related to this:
https://openai-corpws.slack.com/archives/C0AQLHB4U75/p1778660267922549
## What Changed
- Adds `features.multi_agent_v2.non_code_mode_only`, including config
resolution, profile override handling, and generated schema coverage.
- Introduces `ToolExposure::DirectModelOnly` so a tool can be included
in the initial model-visible list while staying out of the nested
code-mode tool surface.
- Applies that exposure to the multi-agent v2 tools when the new flag is
set: `spawn_agent`, `send_message`, `followup_task`, `wait_agent`,
`close_agent`, and `list_agents`.
- Updates code-mode-only filtering so direct-model-only tools remain
visible while ordinary nested code-mode tools are still hidden.
## Verification
- Added config parsing/profile tests for `non_code_mode_only`.
- Added tool spec coverage for the code-mode-only multi-agent v2
exposure behavior.
## Why
Recent session history showed no active use of the raw `shell`,
`local_shell`, or `container.exec` execution surfaces. Keeping those
handlers/specs wired into core leaves duplicate shell execution paths
alongside the supported `shell_command` and unified exec tools.
## What changed
- Removed the raw `shell` handler/spec and its `ShellToolCallParams`
protocol helper.
- Removed the legacy `local_shell` and `container.exec` handler/spec
plumbing while preserving persisted-history compatibility for old
response items.
- Normalized model/config `default` and `local` shell selections to
`shell_command`.
- Pruned tests that exercised removed raw-shell/local-shell/apply-patch
variants and kept coverage on `shell_command`, unified exec, and
freeform `apply_patch`.

the hyphenated forms as `_` is rejected by some proxies

## What
- Keep `session-id` and `thread-id`
- Remove the underscore aliases
## Why
Deferred tools were tracked with separate side-channel filtering after
tool specs had already been assembled. That made the registry
responsible for executing tools while the router/spec planner separately
decided whether those same tools should be exposed to the model up
front.
This PR makes exposure part of the tool handler contract so direct
versus deferred availability travels with the executable tool
registration.
Next step will be to simplify registration
## What Changed
- Adds `ToolExposure` to `codex-tools` and exposes it through
`ToolExecutor`, defaulting tools to `Direct`.
- Teaches dynamic tools and MCP handlers to mark deferred tools as
`Deferred` at construction time.
- Renames the registry object-safe wrapper from `AnyToolHandler` to
`RegisteredTool` and uses `ToolExposure` when deciding whether to
include a handler's spec in the initial model-visible tool list.
- Refactors tool spec planning to derive direct specs and deferred
search entries from registered handlers, removing the router's
special-case deferred dynamic tool filtering.
## Verification
- Not run.
## Why
Codex intentionally ignores unknown `config.toml` fields by default so
older and newer config files keep working across versions. That leniency
also makes typo detection hard because misspelled or misplaced keys
disappear silently.
This change adds an opt-in strict config mode so users and tooling can
fail fast on unrecognized config fields without changing the default
permissive behavior.
This feature is possible because `serde_ignored` exposes the exact
signal Codex needs: it lets Codex run ordinary Serde deserialization
while recording fields Serde would otherwise ignore. That avoids
requiring `#[serde(deny_unknown_fields)]` across every config type and
keeps strict validation opt-in around the existing config model.
## What Changed
### Added strict config validation
- Added `serde_ignored`-based validation for `ConfigToml` in
`codex-rs/config/src/strict_config.rs`.
- Combined `serde_ignored` with `serde_path_to_error` so strict mode
preserves typed config error paths while also collecting fields Serde
would otherwise ignore.
- Added strict-mode validation for unknown `[features]` keys, including
keys that would otherwise be accepted by `FeaturesToml`'s flattened
boolean map.
- Kept typed config errors ahead of ignored-field reporting, so
malformed known fields are reported before unknown-field diagnostics.
- Added source-range diagnostics for top-level and nested unknown config
fields, including non-file managed preference source names.
### Kept parsing single-pass per source
- Reworked file and managed-config loading so strict validation reuses
the already parsed `TomlValue` for that source.
- For actual config files and managed config strings, the loader now
reads once, parses once, and validates that same parsed value instead of
deserializing multiple times.
- Validated `-c` / `--config` override layers with the same
base-directory context used for normal relative-path resolution, so
unknown override keys are still reported when another override contains
a relative path.
### Scoped `--strict-config` to config-heavy entry points
- Added support for `--strict-config` on the main config-loading entry
points where it is most useful:
- `codex`
- `codex resume`
- `codex fork`
- `codex exec`
- `codex review`
- `codex mcp-server`
- `codex app-server` when running the server itself
- the standalone `codex-app-server` binary
- the standalone `codex-exec` binary
- Commands outside that set now reject `--strict-config` early with
targeted errors instead of accepting it everywhere through shared CLI
plumbing.
- `codex app-server` subcommands such as `proxy`, `daemon`, and
`generate-*` are intentionally excluded from the first rollout.
- When app-server strict mode sees invalid config, app-server exits with
the config error instead of logging a warning and continuing with
defaults.
- Introduced a dedicated `ReviewCommand` wrapper in `codex-rs/cli`
instead of extending shared `ReviewArgs`, so `--strict-config` stays on
the outer config-loading command surface and does not become part of the
reusable review payload used by `codex exec review`.
### Coverage
- Added tests for top-level and nested unknown config fields, unknown
`[features]` keys, typed-error precedence, source-location reporting,
and non-file managed preference source names.
- Added CLI coverage showing invalid `--enable`, invalid `--disable`,
and unknown `-c` overrides still error when `--strict-config` is
present, including compound-looking feature names such as
`multi_agent_v2.subagent_usage_hint_text`.
- Added integration coverage showing both `codex app-server
--strict-config` and standalone `codex-app-server --strict-config` exit
with an error for unknown config fields instead of starting with
fallback defaults.
- Added coverage showing unsupported command surfaces reject
`--strict-config` with explicit errors.
## Example Usage
Run Codex with strict config validation enabled:
```shell
codex --strict-config
```
Strict config mode is also available on the supported config-heavy
subcommands:
```shell
codex --strict-config exec "explain this repository"
codex review --strict-config --uncommitted
codex mcp-server --strict-config
codex app-server --strict-config --listen off
codex-app-server --strict-config --listen off
```
For example, if `~/.codex/config.toml` contains a typo in a key name:
```toml
model = "gpt-5"
approval_polic = "on-request"
```
then `codex --strict-config` reports the misspelled key instead of
silently ignoring it. The path is shortened to `~` here for readability:
```text
$ codex --strict-config
Error loading config.toml:
~/.codex/config.toml:2:1: unknown configuration field `approval_polic`
|
2 | approval_polic = "on-request"
| ^^^^^^^^^^^^^^
```
Without `--strict-config`, Codex keeps the existing permissive behavior
and ignores the unknown key.
Strict config mode also validates ad-hoc `-c` / `--config` overrides:
```text
$ codex --strict-config -c foo=bar
Error: unknown configuration field `foo` in -c/--config override
$ codex --strict-config -c features.foo=true
Error: unknown configuration field `features.foo` in -c/--config override
```
Invalid feature toggles are rejected too, including values that look
like nested config paths:
```text
$ codex --strict-config --enable does_not_exist
Error: Unknown feature flag: does_not_exist
$ codex --strict-config --disable does_not_exist
Error: Unknown feature flag: does_not_exist
$ codex --strict-config --enable multi_agent_v2.subagent_usage_hint_text
Error: Unknown feature flag: multi_agent_v2.subagent_usage_hint_text
```
Unsupported commands reject the flag explicitly:
```text
$ codex --strict-config cloud list
Error: `--strict-config` is not supported for `codex cloud`
```
## Verification
The `codex-cli` `strict_config` tests cover invalid `--enable`, invalid
`--disable`, the compound `multi_agent_v2.subagent_usage_hint_text`
case, unknown `-c` overrides, app-server strict startup failure through
`codex app-server`, and rejection for unsupported commands such as
`codex cloud`, `codex mcp`, `codex remote-control`, and `codex
app-server proxy`.
The config and config-loader tests cover unknown top-level fields,
unknown nested fields, unknown `[features]` keys, source-location
reporting, non-file managed config sources, and `-c` validation for keys
such as `features.foo`.
The app-server test suite covers standalone `codex-app-server
--strict-config` startup failure for an unknown config field.
## Documentation
The Codex CLI docs on developers.openai.com/codex should mention
`--strict-config` as an opt-in validation mode for supported
config-heavy entry points once this ships.
## Why
`just fmt` should align source formatting without resolving dependencies
or rewriting lockfiles. The Python SDK formatting steps run through
`uv`, so differing local `uv` versions could decide the SDK lock was
stale and mutate `sdk/python/uv.lock` before Ruff ran.
## What
- Add `--frozen` to both Python SDK `uv run ... ruff` commands in the
root `fmt` recipe.
- Update the existing Python SDK artifact workflow guard test so future
changes keep the formatter recipe non-lock-mutating.
## Verification
- `uv run --frozen --project ../sdk/python --extra dev pytest
../sdk/python/tests/test_artifact_workflow_and_binaries.py -q`
## Why
`chatwidget.rs` is still carrying too many unrelated responsibilities in
one file. #22269 started a five-phase cleanup to move coherent behavior
domains into focused modules while keeping `chatwidget.rs` as the
composition layer. #22407 completed phase 2 by extracting input and
submission flow.
This PR is phase 3. It keeps moving high-churn event handling out of the
central widget by extracting protocol, replay, streaming, and tool
lifecycle handling without changing the visible behavior those flows
already provide. This is once again just a mechanical movement of
existing functions. No functional changes.
## What Changed
- Added focused modules for protocol request dispatch, replay rendering,
assistant/plan/reasoning streaming, turn runtime bookkeeping, hook
lifecycle handling, command lifecycle handling, tool lifecycle
rendering, and interactive tool request prompts.
- Kept active-cell grouping, transcript invalidation, interrupt
deferral, and final-message separator behavior in the same flows, just
moved into smaller files.
- Added module header comments to the new files so the ownership
boundaries are explicit.
- Left `codex-rs/tui/src/chatwidget.rs` as the registration and
orchestration surface for these extracted behaviors.
## Cleanup Phases
The five-phase cleanup plan from #22269 is:
1. Phase 1: mechanical helper and state moves. Completed in #22269.
2. Phase 2: extract input and submission flow, including queued user
messages, shell prompt submission, pending steer restoration, and thread
input snapshot/restore behavior. Completed in #22407.
3. Phase 3: extract protocol, replay, streaming, and tool lifecycle
handling, while preserving active-cell grouping, transcript
invalidation, interrupt deferral, and final-message separator behavior.
This PR.
4. Phase 4: extract settings, popups, and status surfaces, including
model/reasoning/collaboration/personality popups, permission prompts,
rate-limit UI, and connectors helpers.
5. Phase 5: clean up the remaining constructor and orchestration code
once the larger behavior domains have moved out, leaving `chatwidget.rs`
as the composition layer.
## Why
The memories extension has several distinct responsibilities:
registering its prompt and tool contributors, enforcing local-memory
filesystem boundaries, implementing list/read/search behavior, and
wrapping that backend as extension tools. Those responsibilities were
concentrated in `lib.rs`, `local.rs`, and the tool modules, which made
follow-up work harder to review and risked growing files through
unrelated edits.
This PR reorganizes the crate so each responsibility has a narrower
owner while preserving the same extension entrypoint and memory tool
behavior.
## What Changed
- Moved extension lifecycle, prompt, and tool registration into
`src/extension.rs`, leaving `src/lib.rs` as the small crate entrypoint.
- Split `LocalMemoriesBackend` helpers into `local/list.rs`,
`local/path.rs`, `local/read.rs`, and `local/search.rs`.
- Centralized tool names and limits at the crate level, and kept the
backend and extension implementation crate-private.
- Made `memory_list`, `memory_read`, and `memory_search` tool executors
generic over `MemoriesBackend`, so tests can exercise the full executor
path without depending on tool internals.
- Consolidated and expanded memory extension tests in `src/tests.rs`,
including read/search tool output coverage, multi-query search, windowed
`all_within_lines`, and legacy `query` rejection.
## Testing
- Not run locally.
## Why
Picker-style UI in the TUI has accumulated a mix of hardcoded navigation
keys. Some lists supported page movement, some did not; some accepted
Vim-like keys, while others only accepted arrows; and tabbed or
horizontally adjustable pickers had no shared keymap action for
left/right movement.
This PR makes picker/list navigation consistent and configurable so
users can rely on the same defaults across the TUI.
## What Changed
- Adds shared list keymap actions for:
- vertical movement: `move_up`, `move_down`
- horizontal movement: `move_left`, `move_right`
- paging and jumps: `page_up`, `page_down`, `jump_top`, `jump_bottom`
- Adds defaults:
- Up/down: arrows, `Ctrl+P/N`, `Ctrl+K/J`, and plain `k/j` where text
input is not active
- Page up/down: `PageUp/PageDown` and `Ctrl+B/F`
- First/last: `Home/End`
- Left/right: `Left/Right` and `Ctrl+H/L`
- Wires the shared list keymap through picker and list surfaces
including session resume, multi-select, tabbed selection lists,
settings-style lists, app-link selection, MCP elicitation,
request-user-input, and the OSS selection wizard.
- Keeps search behavior intact by reserving printable characters for
query text in searchable pickers.
- Updates keymap setup actions, config schema, snapshots, and focused
coverage for the new list actions.
## How to Test
1. Start Codex from this branch and open the session picker, for example
with an existing session history.
2. In the session list, verify that `Ctrl+J/K` moves the selection
down/up.
3. Verify that `Ctrl+F/B` pages down/up and `Home/End` jumps to the
first/last visible session.
4. Type printable search text such as `j` or `k` and confirm it updates
the query instead of navigating.
5. Focus a picker control that changes values horizontally, such as a
session picker toolbar control, and verify `Ctrl+H/L` changes the
focused value like left/right arrows.
Targeted tests run:
- `cargo test -p codex-tui keymap::tests::`
- `cargo test -p codex-tui keymap_setup::tests::`
- `cargo test -p codex-tui horizontal_list_keys`
- `cargo test -p codex-tui page_and_jump_navigation_use_list_keymap`

- `cargo test -p codex-tui
switching_tabs_changes_visible_items_and_clears_search`
- `cargo test -p codex-tui toggle_sort_key_reloads_with_new_sort`
Also ran `just write-config-schema`, `just fmt`, `just fix -p
codex-tui`, `just argument-comment-lint`, and `git diff --check`.
Note: `cargo test -p codex-tui` was attempted and still aborts in the
pre-existing
`tests::fork_last_filters_latest_session_by_cwd_unless_show_all` stack
overflow, which is unrelated to this branch.
## Why
Extensions can observe thread and turn lifecycle events today, but there
was no single host-owned hook for changes to the effective thread
configuration. That makes features that need to react to model,
permission, or tool-suggest updates either depend on individual mutation
paths or risk going stale after runtime config refreshes.
This adds a typed config-change contributor so extension-owned state can
stay synchronized with the effective thread config while the host
remains responsible for deciding when config changed.
## What Changed
- Added `ConfigContributor<C>` to `codex_extension_api`, with
before/after immutable snapshots of the effective config plus
session/thread extension stores.
- Added registry builder/accessor support through `config_contributor`
and `config_contributors`.
- Emits config-change callbacks after committed updates from session
settings, per-turn setting updates, and `refresh_runtime_config`.
- Builds effective config snapshots only when config contributors are
registered, and suppresses no-op callbacks when the before/after
snapshots are equal.
- Added a core session regression test that verifies contributors
observe both model changes and user-layer runtime config changes,
including access to session and thread extension stores.
## Validation
Added `config_change_contributor_observes_effective_config_changes` in
`codex-rs/core/src/session/tests.rs` to cover the new contributor path.
## Why
Spawned agents can already override `model` and `reasoning_effort`, but
they have no equivalent way to opt into a model-supported service tier.
That makes it impossible to preserve or intentionally select tiered
execution behavior when delegating work to a sub-agent, even though the
model catalog already advertises supported `service_tiers`.
## What changed
- Add optional `service_tier` to both legacy and `MultiAgentV2`
`spawn_agent` tool inputs.
- Show each picker-visible model's supported service tier ids and
descriptions in the `spawn_agent` tool guidance.
- Resolve service tier selection after the child agent's effective model
is known.
- Inherit the parent tier when omitted and still supported by the final
child model; otherwise clear it.
- Reject explicit unsupported tier requests with a model-facing error.
- Keep explicit `service_tier` usable on full-history forks, while still
honoring the existing model/reasoning fork restrictions.
- Hide `service_tier` alongside other spawn metadata when
`hide_spawn_agent_metadata` is enabled.
## Verification
Added focused coverage for:
- v1/v2 `spawn_agent` schema exposure for `service_tier`
- tier descriptions in spawn guidance
- hidden-metadata suppression
- explicit supported tier selection
- explicit unknown and unsupported tier rejection
- inherited tier preservation or clearing based on child-model support
- full-history fork acceptance for explicit service tiers in both v1 and
v2
Local Rust tests were not run in this workspace per repo guidance; the
new coverage is included for CI.
## Why
We added Zellij-specific TUI workarounds because older Zellij behavior
did not work with Codex's normal terminal model:
- #8555 made `tui.alternate_screen = "auto"` disable alternate screen in
Zellij so transcript history stayed available.
- #16578 avoided scroll-region operations in Zellij by emitting raw
newlines and using a separate composer styling path.
This PR removes both workarounds because the latest Zellij release
tested locally (`zellij 0.44.1`) works correctly with Codex's standard
TUI behavior: normal alternate-screen handling, redraw, and history
insertion.
## What Changed
- Removed the `InsertHistoryMode::Zellij` path and the Zellij-only
newline scrollback insertion behavior.
- Removed cached `is_zellij` state from the TUI and composer.
- Removed Zellij-specific composer styling, the helper snapshot, and the
`TerminalInfo::is_zellij()` convenience method that only served this
workaround.
- Changed `tui.alternate_screen = "auto"` to use alternate screen for
Zellij too; `--no-alt-screen` and `tui.alternate_screen = "never"` still
preserve the inline mode escape hatch.
- Updated the generated config schema description for
`tui.alternate_screen`.
## How to Test
Manual smoke path used with `zellij 0.44.1`:
1. Build and run this branch inside a Zellij `0.44.1` session with
default config.
2. Start Codex normally and produce enough assistant/tool output to
create scrollback.
3. Confirm the transcript remains readable, the composer renders
normally, and scrolling through terminal history works.
4. Resize the Zellij pane while output exists and confirm the TUI
redraws without duplicated, missing, or stale rows.
5. Compare with `--no-alt-screen` or `-c tui.alternate_screen=never` if
you want to verify the inline fallback still works.
Targeted tests:
- `just write-config-schema`
- `just fmt`
- `just fix -p codex-tui`
- `cargo test -p codex-terminal-detection`
- `cargo test -p codex-tui alternate_screen_auto_uses_alt_screen`
Attempted but did not complete locally:
- `cargo test -p codex-tui` built and ran the new test successfully,
then failed later on unrelated local failures in
`status_permissions_full_disk_managed_*` and a stack overflow in
`tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.

No developers.openai.com Codex documentation update is needed for this
revert.
