## TL;DR
When you press Esc or Ctrl+C after sending a prompt but before any
output was rendering, it restores the last composer and the message.
## Summary
Cancelling a prompt immediately after submission should behave like
returning to edit that prompt, not like discarding the user's draft.
Today, pressing `Esc` or `Ctrl+C` before Codex responds leaves the
submitted prompt in the transcript and returns an empty composer,
forcing the user to recall or retype it.
When an interrupted turn has not produced substantive visible output,
restore its submitted prompt directly into the composer and roll back
that latest turn. This also covers the first prompt in a fresh thread,
before the TUI has retained a local user-history cell. The restored
draft keeps its text, image attachments, and active collaboration mode
so it can be edited and resubmitted in place.
Restoration is intentionally suppressed once the turn has produced
user-visible activity such as assistant output, tool work, hooks, or
patches. A transient thinking status does not make the prompt
ineligible. Rollback also rebuilds terminal scrollback from the retained
transcript cells so repeated cancellations and terminal resizes do not
duplicate history.
## How to Test
1. Start the TUI with `cargo run -p codex-cli --bin codex`.
2. In a fresh thread, submit the first prompt and press `Esc` before
Codex emits substantive output. Confirm that the prompt returns to the
composer for editing and its submitted transcript row is removed.
3. Repeat with `Ctrl+C`, then repeat after at least one completed turn.
Confirm the same behavior.
4. Submit a prompt, wait for assistant output or tool activity, then
cancel. Confirm that the transcript remains intact and the prompt is not
restored into the composer.
5. Cancel several output-free prompts and resize the terminal between
attempts. Confirm that the startup banner, tip, and transcript history
do not duplicate in scrollback.
Targeted tests:
- `just test -p codex-tui cancelled_turn_edit_restores_prompt`
- `just test -p codex-tui
output_free_interrupted_turn_requests_prompt_restore`
- `just test -p codex-tui

- `just test -p codex-tui
thinking_status_keeps_cancelled_turn_prompt_restore_eligible`
- `just test -p codex-tui
patch_activity_prevents_cancelled_turn_prompt_restore`
The full `just test -p codex-tui` run completed with `2746` passing
tests and two unrelated existing guardian feature-flag failures. `just
argument-comment-lint` remains blocked locally by the existing Bazel
LLVM `compiler-rt` sanitizer-header glob failure; the touched Rust diff
was manually audited for positional literal comments.
# Why
Managed requirements can already constrain sandbox policy choices, but
Windows sandbox implementation selection was still resolved
independently from those requirements. That left the TUI able to
continue through the unelevated fallback even when an organization wants
to require the elevated Windows sandbox implementation.
# What
- Add `[windows].allowed_sandbox_implementations` requirements support
for the Windows `elevated` and `unelevated` implementations.
- Apply that allowlist during core config resolution so disallowed
configured or feature-selected Windows sandbox implementations fall back
to an allowed implementation with the existing requirements warning
path.
- Reuse the existing TUI Windows setup prompts to block disallowed
unelevated continuation, keep required elevated setup in front of the
user, and refuse to persist a TUI-selected Windows sandbox mode that
requirements disallow.
# Semantics
| Allowed | Selected | Effective |
| --- | --- | --- |
| `["elevated"]` | `unelevated` / unset | `elevated` |
| `["unelevated"]` | `elevated` / unset | `unelevated` |
| `["elevated", "unelevated"]` | `elevated` | `elevated` |
| `["elevated", "unelevated"]` | `unelevated` | `unelevated` |
| `["elevated", "unelevated"]` | unset | `elevated` |
Availability is handled by interactive setup surfaces after allowlist
resolution. If the effective elevated implementation is not ready,
elevated-only requirements block on setup. When unelevated is also
allowed, the UI may offer the existing unelevated fallback.
## TUI Screens
If elevated setup is not already complete:
```
Your organization requires the default Codex agent sandbox to continue. Set it up to protect your files and control
network access.
Learn more <https://developers.openai.com/codex/windows>
› 1. Set up default sandbox (requires Administrator permissions)
2. Quit
```
If admin setup fails under `["elevated"]`:
```
Couldn't set up your sandbox with Administrator permissions
Your organization requires the default sandbox before Codex can continue.
Learn more <https://developers.openai.com/codex/windows>
› 1. Try setting up admin sandbox again
2. Quit
```
# Next Steps
- extend the requirements/readout surface, such as
`configRequirements/read`, so clients can inspect the loaded
`[windows].allowed_sandbox_implementations` requirement instead of
inferring it from Windows setup state
- consider extending `windowsSandbox/readiness` as well
- update the App startup guide, setup flow, and banner surfaces so an
elevated-only requirement omits any continue-unelevated escape hatch and
blocks startup until a permitted implementation is ready;
- preserve the existing unelevated fallback path when requirements allow
it, including the `["unelevated"]` case where elevated is disallowed
## Why
TUI users can archive saved sessions from other surfaces, but there is
no in-session command for archiving the active session. Since archiving
the active session also exits the TUI, the command should ask for
explicit confirmation instead of firing immediately.
I'm also working on [a companion
PR](https://github.com/openai/codex/pull/25021) that adds `codex
archive` and `codex unarchive` top-level CLI commands.
## What changed
- Adds a new `/archive` slash command described as `archive this session
and exit`.
- Shows a confirmation dialog with `No, don't archive` selected first
and `Yes, archive and exit` as the explicit action.
- On confirmation, calls the existing `thread/archive` app-server RPC
for the active main session and exits after success.
- Keeps `/archive` disabled while a task is running and unavailable in
side conversations.
## Verification
Added focused TUI coverage for the `/archive` confirmation flow,
disabled-while-task-running behavior, and the `/ar` slash-command popup
snapshot.
## Summary
The desktop app now presents the on-request permissions mode as `Ask for
approval` and the manual-review-backed mode as `Approve for me`. The TUI
still exposed older/internal labels like `Default` and `Auto-review`,
which made the same underlying settings look different across clients.
This updates the TUI UX copy to match the app without changing the
underlying default behavior. Fresh threads continue to use the existing
on-request approval mode, now displayed as `Ask for approval`.
The label changes cover `/permissions`, explicit profile permissions
menus, status surfaces, config persistence history/error text, and the
corresponding TUI snapshots.

# Why
Fixes#24529. Completed hook output in the TUI rendered each
`HookOutputEntry` as one ratatui line, so explicit newlines inside hook
output were not shown as separate transcript rows. That made multiline
`SessionStart.additionalContext` hard to inspect even though the
model-facing context path preserved the original text.
# What
- Split completed hook output entries on explicit newlines before
rendering them in `codex-rs/tui/src/history_cell/hook_cell.rs`.
- Keep the hook output prefix, such as `hook context:` or `warning:`, on
the first physical line only.
- Preserve explicit blank lines and render continuation lines with the
hook body indent.
- Add unit coverage for multiline context and warning output, plus a
chatwidget snapshot regression for `SessionStart` history output.
# Testing
- `cargo nextest run -p codex-tui completed_hook_multiline
hook_completed_before_reveal_renders_completed_without_running_flash`
- `just argument-comment-lint -p codex-tui -- --ignore-rust-version
--lib --tests`
## Why
When the TUI resumes a thread, transcript replay renders prior user
messages but did not seed the composer history. That leaves the resumed
session with empty in-memory prompt history, so pressing Up can fall
through to persisted global history and surface a prompt from another
thread.
The expected behavior is that prompts from the resumed thread are
recalled first, with global history only as a fallback.
## What changed
- Record replayed user messages into the composer history during resume
replay.
- Preserve the existing persisted history format and avoid any startup
history scan.
- Add focused TUI coverage showing replayed prompts are recalled before
persisted global history.
## Validation
- Added `replayed_user_messages_seed_composer_history` in
`codex-rs/tui/src/chatwidget/tests/history_replay.rs`.
- `just test -p codex-tui replayed_user_messages_seed_composer_history`
passed.
## Why
#23813 switches the Windows sandbox runner path to `PermissionProfile`,
but it still left one runtime anchor for resolving symbolic
`:workspace_roots` entries. That is not enough once a turn has multiple
effective workspace roots: exact entries and deny globs under
`:workspace_roots` need to be materialized for every runtime root before
the command runner chooses token mode or builds ACL plans.
## What Changed
- Replaces the Windows runner/setup `permission_profile_cwd` plumbing
with `workspace_roots: Vec<AbsolutePathBuf>`.
- Resolves Windows-local `PermissionProfile` data with
`materialize_project_roots_with_workspace_roots(...)` instead of the
single-cwd helper.
- Threads `Config::effective_workspace_roots()` through core execution,
unified exec, TUI setup/read-grant flows, app-server setup, app-server
`command/exec`, and `debug sandbox` on Windows.
- Preserves those workspace roots through the zsh-fork escalation
executor instead of rebuilding them from `sandbox_policy_cwd`.
- Makes `ExecRequest::new(...)` and the remaining
`build_exec_request(...)` helper path take
`windows_sandbox_workspace_roots` explicitly so new call sites cannot
silently fall back to `vec![cwd]`.
- Clarifies the `debug sandbox` non-Windows comment: remaining
cwd-dependent resolution still uses `sandbox_policy_cwd`, while
`:workspace_roots` entries are already materialized from config roots.
- Updates elevated runner IPC `SpawnRequest` to send `workspace_roots`
and bumps the framed IPC protocol version to `3` for the payload shape
change.
- Adds Windows-local resolver coverage for expanding exact and glob
`:workspace_roots` entries across multiple roots, plus core helper
coverage proving explicit roots are preserved.

A local macOS cross-check with `cargo check --target
x86_64-pc-windows-msvc ...` did not reach crate Rust code because native
dependencies require Windows SDK headers (`windows.h` / `assert.h`) in
this environment; Windows CI remains the real target validation.
Two local targeted filters compile but do not run assertions on macOS:
`env -u CODEX_NETWORK_PROXY_ACTIVE -u CODEX_NETWORK_ALLOW_LOCAL_BINDING
just test -p codex-app-server --lib command_exec_processor` matched zero
tests, and `just test -p codex-linux-sandbox landlock` matched zero
tests because the landlock suite is Linux-only.
## Summary
Adds an optional `clientId` field to app-server v2 `UserInput` and
carries it through the core `UserInput` model so clients can correlate
echoed user input items without relying on payload equality.
## Details
- Adds `client_id: Option<String>` to core `UserInput` variants.
- Exposes the v2 app-server field as `clientId` on the wire and in
generated TypeScript.
- Preserves the id when converting between app-server v2 and core
protocol types.
- Regenerates app-server schema fixtures.
## Validation
- `just fmt`
- `just write-app-server-schema`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-protocol`
- `just fix -p codex-app-server-protocol`
- `just fix -p codex-protocol`
- `git diff --check`
This change keeps unified @mentions behind the mentions_v2 gate, moves
the flag to under-development, and polishes mention rendering/history
behavior.
It also adds a few small improvements to the mentions feature around
mention rendering and history round-tripping for plugin/tool mentions in
message edit scenarios. Plugin selections now insert `@` mentions with
better casing, and saved history preserves the visible sigil so recalled
messages look the same as what the user typed.
- Preserves `@` sigils when encoding/decoding mention history for
tool/plugin paths.
- Improves plugin mention insertion so display names/casing are
reflected more cleanly in the composer.
- Update composer to render user-entered plugin mentions in the same
color as the mentions menu. ALso applies to recalled/edited messages.
- Left/right arrows no longer switch unified-mention search modes after
an @mention has already been accepted (Ex: arrowing left through a
composed message that contains @mentions).
- Keeps bound mentions stable around punctuation, so accepted `@`
mentions do not reopen the popup and punctuated `$` mentions still
persist to cross-session history.
**Steps to test**
- Ensure mentions_v2 is enabled through configuration or `--enable
mentions_v2`
- Type `@` in the TUI composer and verify filesystem/plugin/skill
results are displayed in the unified mentions menu.
- Select a plugin mention from the `@` popup and confirm the inserted
text is an `@...` mention with casing, then recall/edit the message and
confirm it still renders as `@...`.
- Mention a skill and verify that skills still insert as `$skill`
mentions rather than `@` mentions.
- Verify punctuated mentions such as `@plugin.` and `($skill)` keep
their bound mention behavior across editing and history recall.
## Why
Wrapped URLs in rich TUI output, especially URLs rendered inside
Markdown tables, are split across terminal rows. In terminals that
support OSC 8 hyperlinks, treating each visible fragment as part of the
complete destination enables reliable open-link and copy-link actions
even after table layout wraps the URL.
This addresses the semantic-link portion of #12200 and the behavior
described in
https://github.com/openai/codex/issues/12200#issuecomment-4535452980. It
does not change ordinary drag-selection across bordered table rows.
## What Changed
- Added shared TUI OSC 8 support that validates `http://` and `https://`
destinations, sanitizes terminal payloads, and applies metadata
separately from visible line width/layout.
- Added semantic web-link annotations to assistant and proposed-plan
Markdown, including explicit web links and bare web URLs in prose and
table cells while excluding code and non-web Markdown destinations.
- Preserved complete URL targets through table wrapping, narrow pipe
fallback, streaming, transcript overlay rendering, history insertion,
and resize replay.
- Routed intentional Codex-owned links in notices,
status/setup/app-link, feedback, onboarding, MCP/plugin help, memories,
and update surfaces through the shared hyperlink handling.
## How to Test
1. Run Codex in a terminal with OSC 8 link support, such as Ghostty, and
request an assistant response containing a Markdown table whose last
column contains a long `https://` URL.
2. Make the terminal narrow enough for the URL to wrap across multiple
bordered table rows.
3. Use the terminal's open-link or copy-link action on more than one
wrapped URL fragment and confirm each fragment resolves to the complete
original URL.
4. Resize the terminal after the table is rendered and repeat the link
action to confirm the destination survives scrollback replay.
5. Open the transcript overlay while rich output is present and confirm
web links remain interactive there.
6. As a regression check, render inline/fenced code containing URL text
and a Markdown link such as
`[https://example.com](mailto:support@example.com)`; confirm these do
not acquire a web OSC 8 destination.
Targeted automated coverage exercised Markdown links and exclusions,
wrapped and pipe-fallback tables, streaming/transcript overlay
propagation, status-link truncation, and rendered word-wrapping cell
alignment. `just test -p codex-tui` was also run; it passed the
hyperlink coverage and reproduced two unrelated existing guardian
feature-flag test failures.
## Stack
- **Current: #24489 [1 of 2]** - render markdown tables in app style.
- **Stacked follow-up: #24636 [2 of 2]** - render cramped markdown
tables as key/value records.
## Why
Markdown tables currently render as boxed terminal grids, which gives
ordinary assistant output a heavier visual treatment than surrounding
rich text. This row-separated layout is the best match for how the App
renders tables, while accented headers remain distinguishable even when
a terminal font renders bold subtly.

## What Changed
- Render markdown tables as padded, aligned rows without an enclosing
box.
- Style table headers with the active syntax-theme accent plus bold
text, while keeping separators low contrast and theme-aware.
- Use a segmented heavy header rule and thin body-row rules, preserving
wrapping, narrow-width fallback, streaming parity, and rich-history
rendering.
- Update focused assertions and snapshots for the final table layout.
## How to Test
1. Render a markdown table in the TUI with several rows and columns.
2. Confirm the header uses the active theme accent, rows use
one-character interior padding, and the table has no enclosing box.
3. Confirm the header is followed by segmented `━` rules and multiple
body rows are separated by muted segmented `─` rules.
4. Render the same table while streaming and in history/raw-mode
toggles; the final rich layout should remain stable.
5. Render a narrow table with long content and verify wrapping or pipe
fallback does not overflow.
## Validation
- `just test -p codex-tui table`
- `just test -p codex-tui streaming::controller::tests`
- `just argument-comment-lint-from-source -p codex-tui -- --all-targets`
- `just fix -p codex-tui`
- `just fmt`
`just test -p codex-tui` was also run after accepting the snapshots; it
fails only in the unrelated existing guardian app tests
`update_feature_flags_disabling_guardian_clears_review_policy_and_restores_default`
and
`update_feature_flags_disabling_guardian_clears_manual_review_policy_without_history`.
## Why
Interrupting an active turn is currently fixed to `Esc`, which is easy
to hit accidentally and cannot be customized through `/keymap`. This
gives users a less accidental binding while preserving the existing
default.
## What Changed
- Adds `tui.keymap.chat.interrupt_turn` to `/keymap`, defaulting to
`esc` and supporting remapping or unbinding.
- Uses the configured interrupt binding for running-turn status, queued
steer interruption, and `request_user_input`, including the visible
hints.
- Preserves local `Esc` behavior for popups, Vim insert mode, and
`/agent` editing while validating conflicts with fixed/backtrack and
request-input navigation bindings.
- Adds behavior and snapshot coverage for remapped interruption paths.
## How to Test
1. Run Codex and open `/keymap`, then set **Interrupt Turn** to `f12`.
2. Start a turn and confirm `Esc` no longer interrupts it while `f12`
does; the running hint should display `f12 to interrupt`.
3. Queue a steer while a turn is running and confirm the preview
displays `f12`; pressing it should interrupt and submit the steer
immediately.
4. Trigger a `request_user_input` prompt and confirm its footer uses
`f12`; with notes open, `Esc` should still clear notes while `f12`
interrupts the turn.
5. Clear the Interrupt Turn binding and confirm the key-specific
interrupt hint is removed while `Ctrl+C` remains available.
Targeted validation:
- `just write-config-schema`
- `just fix -p codex-config`
- `just fix -p codex-tui`
- `just fmt`
- `just argument-comment-lint-from-source -p codex-config -p codex-tui`
- `just test -p codex-config`
- `cargo insta pending-snapshots --manifest-path tui/Cargo.toml`
- `just test -p codex-tui keymap_setup::tests`
- `just test -p codex-tui` (fails in two pre-existing guardian
feature-flag tests unrelated to this diff; the intentional picker
snapshot updates were reviewed and accepted)
## Summary
- Bump the workspace Rust toolchain from `1.93.0` to `1.95.0` across
Cargo, Bazel, CI, release workflows, devcontainers, and the Codex
environment config.
- Refresh `MODULE.bazel.lock` so the Bazel Rust toolchain artifacts
match the new version.
- Leave purpose-specific toolchains unchanged, including the
`argument-comment-lint` nightly and the upstream `rusty_v8` `1.91.0`
build pin.
- Includes fixes for new lints from `just fix` and a few codex-authored
fixes for lints without a suggestion.
## Why
Windows sandbox diagnostics are currently hard to recover from
`/feedback` even though they are often the most useful artifact when
debugging sandbox behavior. Now that sandbox logging uses daily rolling
files, feedback can safely include the current day's sandbox log without
uploading the old ever-growing legacy `sandbox.log`.
## What changed
- Add a `codex-windows-sandbox` helper that resolves the current daily
sandbox log from `codex_home`.
- When feedback is submitted with logs enabled on Windows, app-server
attaches today's sandbox log if it exists.
- Upload the attachment under the stable filename `windows-sandbox.log`,
independent of the dated on-disk filename.
- Keep existing raw `extra_log_files` behavior unchanged for rollout and
desktop log attachments.
## Verification
- `cargo fmt -p codex-app-server -p codex-windows-sandbox`
- `cargo test -p codex-windows-sandbox
current_log_file_path_for_codex_home_uses_sandbox_dir`
- `cargo test -p codex-app-server
windows_sandbox_log_attachment_uses_current_log`
- Manual CLI/TUI `/feedback` test confirmed Sentry received
`windows-sandbox.log`.
## Why
The Windows sandbox runner still carried the old `SandboxPolicy`
compatibility path even though core now computes `PermissionProfile`.
That meant Windows command-runner execution could only see the legacy
projection, so profile-only filesystem rules such as deny globs were not
part of the runner input.
## What Changed
- Removed the Windows-local `SandboxPolicy` parser/export and deleted
`windows-sandbox-rs/src/policy.rs`.
- Changed restricted-token capture/session setup, elevated setup,
world-writable audit, read-root grant, and command-runner session APIs
to accept `PermissionProfile` plus the profile cwd.
- Bumped the elevated command-runner IPC protocol to version 2 because
`SpawnRequest` now carries `permission_profile` /
`permission_profile_cwd` instead of the legacy `policy_json_or_preset` /
`sandbox_policy_cwd` fields.
- Updated core exec, unified exec, debug-sandbox, TUI setup/grant flows,
and app-server setup to pass the actual effective `PermissionProfile`.
- Left regression coverage asserting the old IPC policy fields are
absent and the runner serializes tagged `PermissionProfile` JSON.
## Verification
- `cargo test -p codex-windows-sandbox`
- `cargo test -p codex-core windows_sandbox`
- `cargo test -p codex-app-server
request_processors::windows_sandbox_processor`
- `just fix -p codex-windows-sandbox -p codex-core -p codex-app-server

- `just fix -p codex-cli -p codex-tui`
- `just fix -p codex-windows-sandbox -p codex-tui`
- `rg "\\bSandboxPolicy\\b" codex-rs/windows-sandbox-rs` returned no
matches.
Note: `cargo test -p codex-cli` was attempted but did not reach crate
tests because local disk filled while compiling dependencies (`No space
left on device`). The targeted clippy pass compiled the affected CLI/TUI
surfaces afterward.

* #24108
* __->__ #23813
## Summary
Fix the TUI `$` app mention paths so App Directory rows that are not
accessible are not treated as usable apps.
This includes the core preservation fix from #24104, but expands it to
the other app mention paths:
- preserve app-server `is_accessible` flags when partial
`app/list/updated` snapshots reach the TUI
- require apps to be both accessible and enabled when resolving exact
`$slug` mentions
- require restored/stale `app://...` bindings to point at accessible,
enabled apps before emitting structured app mentions
- remove the now-unused `codex-chatgpt` dependency from `codex-tui`,
which addresses the `cargo shear` failure seen on #24104
## Root Cause
The app server already sends merged app snapshots with accessibility
computed. The TUI handled app-server app list updates as partial app
loads and re-ran the old accessible-app merge path. That path treated
every notification row as accessible, so App Directory entries with
`isAccessible=false` could appear in `$` suggestions.
Regression source: #22914 routed app-list updates through the app server
while reusing the old TUI partial-load handling. Related precursor:
#14717 introduced the partial-load path, but #22914 made it user-visible
for app-server updates.

## Why
Users who opt into named permission profiles through
`default_permissions` or `[permissions.*]` should stay in named-profile
semantics when they open `/permissions`. The legacy picker rewrites
those users into anonymous preset state, which loses the active profile
identity and hides custom configured profiles.
## What changed
- Switch `/permissions` to a profile-aware picker when profile mode is
active.
- Show friendly built-in labels instead of raw `:` profile syntax.
- Include configured custom profiles and their descriptions in the
picker.
- Route selections through the split TUI profile-selection flow below
this PR.
- Add TUI snapshots and regression coverage for built-ins, custom
profiles, and conflicting legacy runtime overrides.

In profile mode, `/permissions` shows the same human-facing built-ins
users already know:
```text
Default
Auto-review
Full Access
Read Only
locked-down
web-enabled
```
Selecting `locked-down` keeps `active_permission_profile =
Some("locked-down")`; selecting a built-in keeps the friendly label
while switching to its named built-in profile.

## Summary
`/mcp` in the TUI should reflect the current loaded thread, including
project-local MCP servers from that thread config. Before this change,
`mcpServerStatus/list` only read the latest global MCP config, so the
active chat could miss project-local servers.
This adds optional `threadId` to `mcpServerStatus/list`. When present,
app-server resolves the loaded thread and lists MCP status from the
refreshed effective config for that thread; when omitted, existing
global config behavior stays unchanged.
The TUI now sends the active chat thread id for `/mcp` and `/mcp
verbose`, carries that origin through the async inventory result, and
ignores stale completions if the user has switched threads before the
fetch returns. The app-server schemas were regenerated.
## Follow-up
Once this app-server API change lands, the desktop app should make the
same `threadId` plumbing so its MCP inventory also uses the current
thread config.
Fixes#23874
## Summary
Fixes#24411.
`/status` currently has no way to show when the TUI is talking to Codex
through a remote transport. That makes embedded local sessions, local
daemon sessions, and true remote sessions look the same, and it hides
the remote server version when debugging connection-specific behavior.
This PR adds a single `Remote` row for non-embedded connections only.
The row shows the sanitized connection address and a dimmed version
parenthetical, preserving the existing status output for embedded local
sessions.

/>
## Verification
- Manually validated when connecting remotely (either implicitly to
local daemon or explicitly)
## Summary
The compact TUI status line already renders rate-limit percentages as
remaining capacity, but the text did not say so. That made high-usage
red indicators ambiguous because values like `weekly 6%` could be read
as either used or remaining.
This PR labels the compact rate-limit values explicitly as `left` across
the status line, terminal title, and setup previews.

## Why
The named-profile `/permissions` picker needs a small TUI action path
that can select permission profiles without folding the menu UI and
profile metadata into the same review.
## What changed
- Carry permission-profile selections through the TUI app event flow.
- Persist selected profiles while preserving the existing approval
settings and guardrail prompts.
- Keep the legacy `/permissions` picker behavior in this layer; the
profile-mode menu stays in the follow-up PR.

Add owning plugin id to MCP tool call items so we can better filter them
at plugin level.
## Summary
- add optional `plugin_id` to MCP tool-call items and legacy begin/end
events
- propagate plugin metadata into emitted core items and app-server v2
`ThreadItem::McpToolCall`
- preserve plugin ids through app-server replay/redaction paths and
regenerate v2 schema fixtures

- A broader `cargo test -p codex-core` run passed core unit tests, then
hit shell/sandbox/snapshot failures in the integration target.
- A broader app-server downstream run hit the existing
`in_process::tests::in_process_start_clamps_zero_channel_capacity` stack
overflow; `cargo test -p codex-exec` also hit the existing sandbox
expectation mismatch in
`thread_lifecycle_params_include_legacy_sandbox_when_no_active_profile`.
## Why
Model catalog responses can now advertise a nullable
`default_service_tier` for each model. Codex needs to preserve three
distinct states all the way from config/app-server inputs to inference:
- no explicit service tier, so the client may apply the current model
catalog default when FastMode is enabled
- explicit `default`, meaning the user intentionally wants standard
routing
- explicit catalog tier ids such as `priority`, `flex`, or future tiers
Keeping those states distinct prevents the UI from showing one tier
while core sends another, especially after model switches or app-server
`thread/start` / `turn/start` updates.
## What Changed
- Plumbed `default_service_tier` through model catalog protocol types,
app-server model responses, generated schemas, model cache fixtures, and
provider/model-manager conversions.
- Added the request-only `default` service tier sentinel and normalized
legacy config spelling so `fast` in `config.toml` still materializes as
the runtime/request id `priority`.
- Moved catalog default resolution to the TUI/client side, including
recomputing the effective service tier when model/FastMode-dependent
surfaces change.
- Updated app-server thread lifecycle config construction so
`serviceTier: null` preserves explicit standard-routing intent by
mapping to `default` instead of internal `None`.
- Kept core responsible for validating explicit tiers against the
current model and stripping `default` before `/v1/responses`, without
applying catalog defaults itself.

`SubagentStop` runs when a thread-spawned subagent turn is about to
finish. Thread-spawned subagents use `SubagentStop` instead of the
normal root-agent `Stop` hook.
Configured handlers match on `agent_type`. Hook input includes the
normal stop fields plus:
- `agent_id`: the child thread id.
- `agent_type`: the resolved subagent type.
- `agent_transcript_path`: the child subagent transcript path.
- `transcript_path`: the parent thread transcript path.
- `last_assistant_message`: the final assistant message from the child
turn, when available.
- `stop_hook_active`: `true` when the child is already continuing
because an earlier stop-like hook blocked completion.
`SubagentStop` shares the same completion-control semantics as `Stop`,
scoped to the child turn:
- No decision allows the child turn to finish.
- `decision: "block"` with a non-empty `reason` records that reason as
hook feedback and continues the child with that prompt.
- `continue: false` stops the child turn. If `stopReason` is present,
Codex surfaces it as the stop reason.
# Lifecycle Scope
Only thread-spawned subagents run `SubagentStop`.
Internal/system subagents such as Review, Compact, MemoryConsolidation,
and Other do not run normal `Stop` hooks and do not run `SubagentStop`.
This avoids exposing synthetic matcher labels for internal
implementation paths.
# Stack
1. #22782: add `SubagentStart`.
2. This PR: add `SubagentStop`.
3. #22882: add subagent identity to normal hook inputs.
## Why
Once a named permission profile is selected, runtime state has to keep
that profile identity intact instead of collapsing back to anonymous
effective permissions. The session refresh path also needs to rebuild
profile-derived network proxy state so active profile switches take
effect consistently.
## What changed
- Preserve the active permission profile through session updates.
- Rebuild profile-derived runtime/network configuration when the active
profile changes.
- Keep the runtime path aligned with the current session configuration
APIs.
- Tighten the affected tests, including the Windows delete-pending
memory-file case that was intermittently tripping CI.

## Why
`main` picked up two small Rust build failures after nearby merges:
- #23507 added a real handler for
`ServerNotification::ThreadSettingsUpdated`, but the same variant was
still listed in the ignored-notification match arm. Full Clippy runs
treat the resulting unreachable-pattern warning as an error.
- #23666 added `turn_id` and `truncation_policy` to
`codex_tools::ToolCall`, while the goal extension backend test fixtures
from the goal-extension work still used the old shape. That left
`codex-goal-extension` tests unable to compile once the branches met on
`main`.
## What changed
Removed the duplicate `ThreadSettingsUpdated` match pattern from
`tui/src/chatwidget/protocol.rs`.
Updated the goal extension test `tool_call` helper to populate the new
`ToolCall` fields, and reused that helper for the one direct literal
that still had the old field list.
## Verification
- `just fix -p codex-tui`
- `cargo test -p codex-goal-extension`
Builds on #23502.
## Why
#23502 adds the app-server `thread/settings/update` API and matching
`thread/settings/updated` notification. The TUI already lets users
change thread-scoped settings such as model, reasoning effort, service
tier, approvals, permissions, personality, and collaboration mode, but
those updates need to flow through the app server so embedded and
connected clients observe the same thread state.
This is a rework (simplification) of PR
https://github.com/openai/codex/pull/22510. It has the same
functionality, but the underlying `thread/settings/update` api is now
simpler in that it no longer returns the effective settings as a
response. Now, clients receive the effective settings only through the
`thread/settings/updated` notification.
## What Changed
This updates the TUI to send `thread/settings/update` whenever those
thread-scoped settings change and to treat the RPC response as the
authoritative acknowledgement. It also routes `thread/settings/updated`
notifications back into cached session state and the visible chat widget
so active and inactive threads stay in sync after app-server-originated
changes.
The implementation is kept to the TUI layer: settings conversion and
merge logic live under `codex-rs/tui/src/app/thread_settings.rs`, with
dispatch/routing hooks in the existing app and chat widget paths.
## Verification
I manually tested using `codex app-server --listen unix://` and then
launching two copies of the TUI that use the same local app server. I
then resumed the same thread on both and verified that changes like plan
mode, fast mode, model, reasoning effort, etc. are reflected "live" in
the second client when modified in the first and vice versa.
## Why
App-server clients need a way to update a thread's next-turn settings
without starting a turn, adding transcript content, or waiting for turn
lifecycle events. This gives settings UI a direct path for durable
thread settings while clients observe the eventual effective state
through a notification.
This is a simplified rework of PR
https://github.com/openai/codex/pull/22509. In particular, it changes
the `thread/settings/update` api to return immediately rather than
waiting and returning the effective (updated) thread settings. This
makes the new api consistent with `turn/start` and greatly reduces the
complexity of the implementation relative to the earlier attempt.
## What Changed
- Adds experimental `thread/settings/update` with partial-update request
fields and an empty acknowledgment response.
- Adds experimental `thread/settings/updated`, carrying full effective
`ThreadSettings` and scoped by `threadId` to subscribed clients for the
affected thread.
- Shares durable settings validation with `turn/start`, including
`sandboxPolicy` plus `permissions` rejection and `serviceTier: null`
clearing.
- Emits the same settings notification when `turn/start` overrides
change the stored effective thread settings.
- Regenerates app-server protocol schema fixtures and updates
`app-server/README.md`.
## Why
After the terminal-probe work in #23175, fresh-session startup still
waits for `thread/start` before the chat input can become usable. The
chat widget already has the machinery to hold early submissions until a
session is configured, so fresh `thread/start` does not need to stay on
the input-ready hot path.
Refs #16335.
## What
This PR starts fresh app-server threads in a background task, reports
completion through a startup app event, and attaches the primary session
once `thread/start` returns. Resume and fork startup paths remain
synchronous.
## Benchmark
In the local pty startup benchmark, this PR's pre-optimization base
branch, #23175, measured about 152ms median from launch to accepted chat
input. The stacked result measured about 66ms median, for an approximate
additional savings of 85-95ms. For broader context, the original `main`
baseline before either startup optimization was about 250.5ms median. We
also measured Codex 0.117.0 on the same machine at about 64.6ms median,
so the stacked branch is back in the old-startup-time range.

## Verification
- `cargo test -p codex-tui`
## Why
Issue #23214 reports `/ps` showing no background terminals while the
status line still says it is waiting for a background terminal. The race
is in core: `write_stdin` can poll a process that exits before the
response returns. The process manager correctly returns `process_id:
None`, but the handler still emitted a `TerminalInteraction` event using
the requested session id, causing clients to believe a dead process was
still being polled.
Fixes#23214.
## What changed
- Suppress `TerminalInteraction` events for empty `write_stdin` polls
once `response.process_id` is `None`.
- Continue emitting interactions for non-empty stdin, even if that input
causes the process to exit before the response returns.
- Extend the unified exec integration test to assert completed empty
polls do not emit terminal interactions.

with a reproducible stack overflow.
# What
`SubagentStart` runs once when Codex creates a thread-spawned subagent,
before that child sends its first model request. Thread-spawned
subagents use `SubagentStart` instead of the normal root-agent
`SessionStart` hook.
Configured handlers match on the subagent `agent_type`, using the same
value passed to `spawn_agent`. When no agent type is specified, Codex
uses the default agent type.
Hook input includes the normal session-start fields plus:
- `agent_id`: the child thread id.
- `agent_type`: the resolved subagent type.
`SubagentStart` may return `hookSpecificOutput.additionalContext`. That
context is added to the child conversation before the first model
request.
# Lifecycle Scope
Only thread-spawned subagents run `SubagentStart`.
Internal/system subagents such as Review, Compact, MemoryConsolidation,
and Other do not run normal `SessionStart` hooks and do not run
`SubagentStart`. This avoids exposing synthetic matcher labels for
internal implementation paths.
Also the `SessionStart` hook no longer fires for subagents, this matches
behavior with other coding agents' implementation
# Stack
1. This PR: add `SubagentStart`.
2. #22873: add `SubagentStop`.
3. #22882: add subagent identity to normal hook inputs.
## Context
The CLI rate-limit surfaces previously described usage windows as fixed
5-hour and weekly limits. We want the CLI to display whatever supported
rate-limit period the server returns instead of assuming a 5-hour/1-week
pair. This supports generalized Codex rate-limit periods.
## Summary
- Formats CLI rate-limit warning/status labels only for the supported
returned window durations: approximate 5h, daily, weekly, monthly, and
annual.
- Uses generic fallback copy when a primary or secondary window has no
duration, so missing secondary protection data does not produce stale
weekly copy.
- Uses generic fallback copy for unsupported window durations instead of
adding arbitrary hourly, multi-day, multi-week, or multi-year labels.
- Updates status line and terminal title setup descriptions/previews to
talk about primary/secondary usage limits rather than fixed 5h/weekly
limits.
- Adds rendered insta snapshot coverage for the updated rate-limit
status surfaces and `/status` fallback labels.
## Tests
Tested locally:
- one primary window
- one secondary window
- primary and secondary window
## Why
Filesystem permission profiles used `none` for deny-read entries, which
is less direct than the action the entry actually represents. This
change makes `deny` the canonical filesystem permission spelling while
preserving compatibility for older configs that still send `none`.
## What changed
- rename `FileSystemAccessMode::None` to `Deny`
- serialize and generate schemas with `deny` as the canonical value
- retain `none` only as a legacy input alias for temporary config
compatibility
- update filesystem glob diagnostics and regression coverage to use the
canonical spelling
- refresh config and app-server schema fixtures to match the new wire
shape
## Validation
- `cargo test -p codex-protocol`
- `cargo test -p codex-app-server-protocol`
- `cargo test -p codex-core config_toml_deserializes_permission_profiles
--lib`
- `cargo test -p codex-core
read_write_glob_patterns_still_reject_non_subpath_globs --lib`
Earlier in the session, a broad `cargo test -p codex-core` run reached
unrelated pre-existing failures in timing/snapshot/git-info tests under
this environment; the targeted surfaces touched by this PR passed
cleanly.
## Why
App and skill toggles are user config mutations too. When the TUI is
attached to a remote app server, writing those toggles into the local
`config.toml` makes the UI report success without updating the server
that actually owns the session.
This is **[2 of 4]** in a stacked series that moves TUI-owned config
mutations onto app-server APIs.
## What changed
- Routed app enable/disable persistence through app-server config batch
writes.
- Routed skill enable/disable persistence through `skills/config/write`.
- Avoided refreshing local config from disk after these writes when the
TUI is connected to a remote app server.
## Config keys affected
- `apps.<app_id>.enabled`
- `apps.<app_id>.disabled_reason`
- `[[skills.config]]` entries keyed by `path`, with `enabled = false`
used for persisted disables
## Suggested manual validation
- Connect the TUI to a remote app server, disable an app, reconnect, and
confirm the app remains disabled from remote config rather than local
disk state.
- Re-enable the same app and confirm both `apps.<app_id>.enabled` and
`apps.<app_id>.disabled_reason` are cleared remotely.
- Disable a skill in the manage-skills UI and confirm a remote
`[[skills.config]]` disable entry appears.
- Re-enable that skill and confirm the disable entry is removed and the
effective enabled state updates without relying on local config reloads.

## Why
Older iTerm2 builds can be detected as supporting the image transport
that terminal pets use, but in practice they fail to render the pet flow
correctly. Instead of silently attempting image rendering, Codex should
tell the user that their iTerm2 version is too old and that upgrading is
the fix.
## What Changed
- gate iTerm2 pet auto-detection on version `3.6.0` or newer
- show a dedicated upgrade message for older or unknown iTerm2 versions
instead of the generic unsupported-terminal warning
- keep the existing generic unsupported-terminal path for non-iTerm
terminals
- add regression coverage for iTerm2 version parsing and the old-iTerm
warning path
## How to Test
1. Start Codex in iTerm2 3.6 or newer.
2. Run `/pets`.
3. Confirm the pets picker opens instead of showing a warning.
4. Start Codex in an older iTerm2 build, or exercise the equivalent test
path.
5. Run `/pets`.
6. Confirm Codex warns that pets require iTerm2 3.6 or newer and tells
the user to upgrade.
7. Also verify that a non-iTerm unsupported terminal still shows the
generic unsupported-terminal message.
Targeted tests:
- `cargo test -p codex-terminal-detection`
- `cargo test -p codex-tui pets::`
- `cargo test -p codex-tui slash_pets_on_unsupported_terminal`
- `cargo test -p codex-tui slash_pets_on_old_iterm2`
Fixes#22300.
## Summary
MCP tool calls can appear in thread history while still in progress.
During replay, `handle_thread_item` routed every
`ThreadItem::McpToolCall` to the completion handler, so an in-progress
item with no result or error was rendered as `MCP tool call completed
without a result`.
This updates replay handling to mirror command executions: `InProgress`
MCP calls go through `on_mcp_tool_call_started`, while completed and
failed calls continue through the completion path.
## Validation
- `cargo test -p codex-tui
replayed_in_progress_mcp_tool_call_stays_active`
## Why
Fixes#21894.
When the TUI handles an MCP elicitation, the request payload already
includes the thread that generated the elicitation.
`ChatWidget::handle_elicitation_request_now` was ignoring that value and
using the currently visible chat thread instead. In a multi-session TUI,
that can send `resolve_elicitation` to an older visible thread rather
than the session that owns the pending elicitation, producing
`elicitation request not found` and leaving the prompt unresolved.
## What changed
- Parse `McpServerElicitationRequestParams.thread_id` in the ChatWidget
elicitation handler and use it for app-link, form, fallback approval,
and auto-decline resolution paths.
- Keep the existing visible-thread fallback only for malformed request
payloads with an invalid thread id.
- Update the invalid URL elicitation regression test so the visible
thread and request thread intentionally differ.
Addresses #23181
## Why
Renamed threads can share names, so hints that suggest resuming directly
by name are ambiguous. Issue #23181 asks for the picker hint to include
the thread name and thread ID in parens so users can disambiguate
safely.
## What
- Adds a shared resume hint formatter for named threads: run `codex
resume`, then select `<name> (<thread-id>)`.
- Uses that hint for /rename confirmations, TUI session summaries, and
CLI/TUI exit messages.
- Keeps direct `codex resume <thread-id>` guidance for unnamed threads.
## Verification
Manually verified that message after `/rename` and after `/exit` include
session ID in parens.

## Why
`/goal` can keep synthesizing turns even when the next turn cannot make
meaningful progress. Hard usage exhaustion can replay failing turns, and
repeated permission or external-resource blockers can keep burning
tokens while waiting for user or system intervention.
## What changed
- Add resumable `blocked` and `usageLimited` goal states. As with
`paused`, goal continuation stops with these states.
- Move to `usageLimited` after usage-limit failures.
- Allow the built-in `update_goal` tool to set `blocked` only under
explicit repeated-impasse guidance. Updated goal continuation prompt to
specify that agent should use `blocked` only when it has made at least
three attempts to get past an impasse.
Most of the files touched by this PR are because of the small app server
protocol update.
## Validation
I manually reproduced a number of situations where an agent can run into
a true impasse and verified that it properly enters `blocked` state. I
then resumed and verified that it once again entered `blocked` state
several turns later if the impasse still exists.
I also manually reproduced the usage-limit condition by creating a
simulated responses API endpoint that returns 429 errors with the
appropriate error message. Verified that the goal runtime properly moves
the goal into `usageLimited` state and TUI UI updates appropriately.
Verified that `/goal resume` resumes (and immediately goes back into
`ussageLImited` state if appropriate).
## Follow-up PRs
Small changes will be needed to the GUI clients to properly handle the
two new states.
## Summary
Fixes#22726.
After a Responses stream disconnect, the live TUI could keep accepting
prompts while leaving partially streamed assistant output in its
transient streaming-cell form. That made fenced diffs or SVG/XML-like
content appear as raw transcript text until the user closed the TUI and
resumed the same session, which rebuilt the transcript from saved
history.
This change finalizes the active answer stream before generic
failed-turn cleanup clears the stream controller, so the live transcript
takes the same source-backed markdown consolidation path as a successful
turn.
## Reviewer repro
1. Start a local Codex TUI session.
2. Trigger an assistant turn that streams markdown content, especially a
fenced diff or SVG/XML-like block.
3. Force or encounter a non-retry stream disconnect before the turn
completes.
4. Continue using the same still-open TUI session.
5. Before this fix, the live history can stay raw/plain even though
`codex resume` renders the same session normally.
6. After this fix, the failed-turn path consolidates the partial stream
before rendering the error, so the live TUI keeps normal transcript
rendering.
## Why
#22891 moved the TUI turn-command path to pass `ActivePermissionProfile`
instead of the full `PermissionProfile`, but the remaining
config/session bridge still accepted the concrete `PermissionProfile`
and active profile id as separate arguments. That shape made it too easy
for future callers to update the concrete profile and active profile id
out of sync.
This PR makes the trusted session snapshot path pass one coherent value
into `Permissions`, while keeping `requirements.toml` enforcement owned
by the existing constrained permission state.
## What Changed
- Added `PermissionProfileSnapshot` as the public snapshot value for
trusted session/config synchronization.
- Changed `Permissions::set_permission_profile_from_session_snapshot()`
and `replace_permission_profile_from_session_snapshot()` to take a
`PermissionProfileSnapshot`.
- Updated the replacement path to derive its constrained
`PermissionProfile` from the snapshot, so callers cannot pass a separate
profile that disagrees with the snapshot.
- Removed the internal tuple-style
`PermissionProfileState::set_active_permission_profile()` mutation path.
- Updated core session projection and TUI call sites to construct
explicit legacy or active snapshots.
- Documented the snapshot constructors so legacy use and id/profile
mismatch hazards are called out at the API boundary.
- Added a focused config test that verifies snapshot updates still
respect existing permission constraints.
## How To Review
1. Start with `codex-rs/core/src/config/resolved_permission_profile.rs`;
`PermissionProfileSnapshot` is the public wrapper, while
`ResolvedPermissionProfile` stays internal.
2. Check `codex-rs/core/src/config/mod.rs` to confirm both
session-snapshot setters validate through `PermissionProfileState` and
no longer accept loose profile/id pairs.
3. Skim `codex-rs/core/src/session/session.rs` for the session
projection path; it now builds the snapshot before installing it.
4. Skim the TUI changes as call-site migration from loose argument pairs
to explicit snapshot construction.
## Verification
- `cargo test -p codex-core
permission_snapshot_setter_preserves_permission_constraints`
- `cargo test -p codex-tui status_permissions_`
- `cargo test -p codex-tui
session_configured_preserves_profile_workspace_roots`
- `just fix -p codex-core -p codex-tui`
## Why
The app server API should expose permission profile identity, not the
lower-level runtime permission model. `PermissionProfile` is the
compiled sandbox/network representation that the server uses internally;
exposing it through app-server-protocol forces clients to understand
details that should remain implementation-level.
The API boundary should prefer `ActivePermissionProfile`: a stable
profile id, plus future parent-profile metadata, that clients can pass
back when they want to select the same active permissions. This also
avoids schema generation collisions between the app-server v2 API type
space and the core protocol model.
Incidentally, while PR makes a number of changes to `command/exec`, note
that we are hoping to deprecate this API in favor of `process/spawn`, so
we don't need to be too finicky about these changes.
## What Changed
- Removed `PermissionProfile` from the app-server-protocol API surface,
including generated schema and TypeScript exports.
- Changed `CommandExecParams.permissionProfile` to
`ActivePermissionProfile`.
- Resolve command exec profile ids through `ConfigManager` for the
command cwd, matching turn override selection semantics.
- Updated downstream TUI tests/helpers to use core permission types
directly instead of app-server-protocol `PermissionProfile` shims.
## Why
This continues the permissions migration by keeping the TUI command
boundary aligned with the app-server protocol direction from #22795:
callers should select a permission profile by id instead of passing a
concrete `PermissionProfile` value around as the turn configuration.
`AppCommand` is internal to the TUI, but it is the path that eventually
becomes `thread/turn/start`, so carrying concrete profile details there
made it too easy for UI code to keep relying on the old whole-profile
replacement model.
## What changed
- `AppCommand::UserTurn` and `AppCommand::OverrideTurnContext` now carry
`Option<ActivePermissionProfile>` instead of `PermissionProfile`.
- Composer submissions copy the active permission profile id from the
current session snapshot; legacy snapshots intentionally submit no
active profile id.
- Permission preset UI events now carry only the active built-in profile
id. The app derives the concrete built-in `PermissionProfile` internally
only when updating its local config/status snapshot.
- Permission presets expose their built-in active profile id, and preset
selection preserves that id in both the immediate turn override and the
local TUI config snapshot.
- Turn routing sends `TurnPermissionsOverride::ActiveProfile` when an
active id is present, and only falls back to the legacy sandbox
projection for the remaining runtime override path.
## How to review
Start with `codex-rs/tui/src/app_command.rs` to verify the command shape
no longer exposes `PermissionProfile`.
Then read `codex-rs/tui/src/app/thread_routing.rs` to verify the
app-server turn-start conversion: active ids go through as ids, while
the legacy sandbox fallback is still constrained to the existing runtime
override case.
Finally, check `codex-rs/tui/src/chatwidget/permission_popups.rs`,
`codex-rs/tui/src/app/event_dispatch.rs`,
`codex-rs/tui/src/app/config_persistence.rs`, and
`codex-rs/utils/approval-presets/src/lib.rs` to see how preset
selections stay id-only across TUI events while the local display/config
mirror still gets a concrete built-in profile.
## Verification
Latest local verification after the id-only `AppEvent` cleanup:
- `cargo check -p codex-tui --tests`
- `cargo test -p codex-tui
permissions_selection_sends_approvals_reviewer_in_override_turn_context`
- `cargo test -p codex-tui update_feature_flags_enabling_guardian`
- `cargo test -p codex-utils-approval-presets`
- `just fmt`
- `just fix -p codex-tui -p codex-utils-approval-presets`
Earlier in the same PR, before the final event-shape cleanup:
- `cargo test -p codex-tui turn_permissions_`
- `cargo test -p codex-tui submission_`
- `cargo test -p codex-tui
session_configured_syncs_widget_config_permissions_and_cwd`
- `RUST_MIN_STACK=16777216 cargo test -p codex-tui`
## Summary
- Add optional image detail to user image inputs across core, app-server
v2, thread history/event mapping, and the generated app-server
schemas/types.
- Preserve requested detail when serializing Responses image inputs:
omitted detail stays on the existing `high` default, while explicit
`original` keeps local images on the original-resolution path.
- Support `high`/`original` consistently for tool image outputs,
including MCP `codex/imageDetail`, code-mode image helpers, and
`view_image`.
## Why
[#22581](https://github.com/openai/codex/pull/22581) started separating
the chat composer’s responsibilities, but `ChatComposer` still owned the
remaining editable draft state alongside footer/status presentation
state. This follow-up makes those ownership lines explicit so future
composer changes have a smaller blast radius and `BottomPane` does not
need to keep exposing scattered draft getters.
This is just a refactor. No functional or behavioral changes are
intended.
## What changed
- Move the remaining editable composer state into
`bottom_pane/chat_composer/draft_state.rs`.
- Move footer and status-row presentation state into
`bottom_pane/chat_composer/footer_state.rs`.
- Add an internal `ComposerDraftSnapshot` for restore flows, replacing
several ad hoc `BottomPane` pass-through reads.
- Rewire the related history-search and thread-input restore paths to
use the extracted state.
## Verification
- `RUST_MIN_STACK=8388608 cargo test -p codex-tui`
- `cargo insta pending-snapshots`
## Why
This PR builds on [#22611](https://github.com/openai/codex/pull/22611).
After `runtimeWorkspaceRoots` moved onto thread state, the user-facing
summaries were still inconsistent about which roots they showed. In
particular, `/status` and the exec startup summary could under-report
extra workspace roots from `--add-dir` or from profile-defined
`workspace_roots`, which made the new model look incorrect even when the
permissions themselves were right.
## What Changed
- switched the TUI status surfaces to summarize against
`Config::effective_workspace_roots()`
- updated the exec human-output summary to render from the effective
permission profile instead of the raw constrained profile
- added focused regressions for both the TUI and exec code paths so
extra workspace roots stay visible in user-facing summaries
## Verification
Targeted coverage for this follow-up lives in:
- `codex-rs/tui/src/status/tests.rs`
- `codex-rs/exec/src/event_processor_with_human_output_tests.rs`
The added regressions verify that:
- status output includes profile-defined workspace roots in the
effective permissions summary
- exec startup output includes runtime workspace roots instead of
collapsing back to `cwd` only
## Why
This PR builds on [#22610](https://github.com/openai/codex/pull/22610)
and is the app-server side of the migration from mutable per-turn
`SandboxPolicy` replacement toward selecting immutable permission
profiles by id plus mutable runtime workspace roots.
Once permission profiles can carry their own immutable
`workspace_roots`, app-server no longer needs to mutate the selected
`PermissionProfile` just to represent thread-specific filesystem
context. The mutable part now lives on the thread as explicit
`runtimeWorkspaceRoots`, while `:workspace_roots` remains symbolic until
the sandbox is realized for a turn.
## What Changed
- Replaced the v2 permission-selection wrapper surface with plain
profile ids for `thread/start`, `thread/resume`, `thread/fork`, and
`turn/start`.
- Removed the API surface for profile modifications
(`PermissionProfileSelectionParams`,
`PermissionProfileModificationParams`,
`ActivePermissionProfileModification`).
- Added experimental `runtimeWorkspaceRoots` fields to the thread
lifecycle and turn-start APIs.
- Threaded runtime workspace roots through core session/thread
snapshots, turn overrides, app-server request handling, and command
execution permission resolution.
- Kept session permission state symbolic so later runtime root updates
and cwd-only implicit-root retargeting rebind `:workspace_roots`
correctly.
- Updated the embedded clients just enough to send and restore the new
thread state.
- Refreshed the generated schema/TypeScript artifacts and the app-server
README to match the new contract.
## Verification
Targeted coverage for this layer lives in:
- `codex-rs/app-server-protocol/src/protocol/v2/tests.rs`
- `codex-rs/app-server/tests/suite/v2/thread_start.rs`
- `codex-rs/app-server/tests/suite/v2/thread_resume.rs`
- `codex-rs/app-server/tests/suite/v2/turn_start.rs`
- `codex-rs/core/src/session/tests.rs`
The key regression checks exercise that:
- `runtimeWorkspaceRoots` resolve against the effective cwd on thread
start.
- Profile-declared workspace roots are excluded from the runtime
workspace roots returned by app-server.
- A turn-level runtime workspace-root update persists onto the thread
and is returned by `thread/resume`.
- A named permission profile selected on one turn remains symbolic so a
later runtime-root-only turn update changes the actual sandbox writes.
- A cwd-only turn update retargets the implicit runtime cwd root while
preserving additional runtime roots.
- The protocol fixtures and generated client artifacts stay in sync with
the string-based permission selection contract.

## Why
`/side` currently lets `Esc` return to the parent thread. Multiple users
reported that this collides with queued-steer UI that also advertises
`Esc`, so a timing-sensitive keypress can dismiss an ephemeral side chat
instead of sending the queued prompt.
After removing that dismissal shortcut, the same `Esc` path could fall
through to main-thread backtrack/edit-previous handling, which is not
valid for ephemeral side conversations. This keeps `/side` out of both
global `Esc` behaviors.
## What changed
- Remove `Esc` from the `/side` return shortcut matcher while keeping
the existing `Ctrl+C` and `Ctrl+D` behavior.
- Update side-conversation hints and blocked-command copy to advertise
`Ctrl+C` as the return shortcut.
- Rename the reserved `Esc` keymap label to describe backtracking only.
- Block backtrack/edit-previous handling while a side conversation is
active and report `Editing previous prompts is unavailable in side
conversations.` when that path would have fired.
- Keep composer-owned `Esc` behavior, such as Vim insert-mode escape,
routed locally.
- Refresh focused shortcut assertions and TUI snapshots for the updated
footer and new side-conversation error message.
## Verification
Manually tested `/side` use cases and `Esc`, `Ctrl+C`, `Ctrl+D`.
