  • Constrain Windows sandbox requirements (#23766)
    # 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
  • Use session wording in /rename confirmation (#25035)
    ## Why
    
    The TUI `/rename` confirmation should use the term "session" for
    consistency.
  • Align TUI permissions labels with app (#25017)
    ## 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.

  • Seed prompt history from resumed messages (#24298)
    ## 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.
  • feat(tui): add OSC 8 web links to rich content (#24472)
    ## 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.
  • Attach Windows sandbox log to feedback reports (#24623)
    ## 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`.
  • tui: keep inaccessible apps out of mentions (#24625)
    ## 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.

  • tui: add named permission profile picker (#21559)
    ## 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.
    
    ## Stack
    
    1. [#22931](https://github.com/openai/codex/pull/22931):
    runtime/session/network propagation for active permission profiles.
    2. [#23708](https://github.com/openai/codex/pull/23708): TUI selection
    plumbing and guardrail flow.
    3. **This PR**: profile-aware `/permissions` menu and custom profile
    display.
    
    ## UX impact
    
    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.

  • Use thread config for TUI MCP inventory (#24532)
    ## 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
  • Show remote connection details in /status (#24420)
    ## 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.

  • tui: plumb permission profile selection (#23708)
    ## 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.

  • Sync TUI thread settings through app server (#23507)
    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.
  • Harden CLI rate limit window labels (#22929)
    ## 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
  • [2 of 4] tui: route app and skill enablement through app server (#22914)
    ## 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.

  • Clarify resume hints for renamed threads (#23234)
    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

  • fix(tui): show shutdown feedback on exit (#23323)
    ## Why
    
    Ctrl+C can take a noticeable amount of time to finish when the TUI is
    waiting for the app-server thread shutdown path to complete. Before this
    change, the UI could look like it had not accepted the shutdown request
    because the composer and cursor remained in their normal interactive
    state during that wait.
    
    This PR makes the accepted shutdown visible immediately. It does not add
    an artificial sleep or change the shutdown timeout; it only draws one
    final feedback frame before continuing through the existing shutdown
    flow.
    
    ## What Changed
    
    - On `ExitMode::ShutdownFirst`, the TUI now renders shutdown feedback
    before awaiting the existing thread shutdown future.
    - The bottom pane disables composer input, which hides the cursor
    through the existing disabled-input cursor path.
    - The composer shows `Shutting down...` as the disabled input hint and
    suppresses footer content so the shutdown acknowledgement is not
    competing with shortcut/status text.
    - The logout path uses the same feedback path before shutting down.
    
    ## How to Test
    
    1. Start Codex from this branch.
    2. Press `Ctrl+C` to request shutdown.
    3. If shutdown takes long enough to observe, confirm the composer
    changes to `› Shutting down...`, the cursor disappears, and no footer
    hint is rendered below it.
    4. Regression check: repeat with text already typed in the composer and
    confirm the visible row still switches to `Shutting down...` while the
    draft remains preserved internally until the process exits.
    
    Targeted tests:
    
    - `cargo test -p codex-tui
    shutdown_in_progress_disables_input_and_uses_hint_without_footer`
    - `cargo test -p codex-tui bottom_pane::footer::tests::`
    
    ## Local Validation Note
    
    `cargo test -p codex-tui` still aborts in
    `app::tests::discard_side_thread_removes_agent_navigation_entry` with a
    stack overflow. That same test also failed when run alone locally, and
    the failure appears unrelated to this shutdown feedback path.
  • core: set permission profiles from snapshots (#22920)
    ## 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`
  • tui: pass active permission profiles through app commands (#22891)
    ## 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`

  • Trim TUI legacy core helper usage (#22695)
    ## Why
    
    The TUI still had a few low-risk dependencies flowing through the
    transitional `legacy_core` namespace after the app-server migration.
    These helpers either already have clearer non-core owners or are
    presentation logic that does not belong in `codex-core`, so moving them
    out reduces the compatibility surface without changing product behavior.
    
    ## What changed
    
    This is a low-risk change, almost completely mechanical in nature.
    
    - Route TUI Codex-home lookup through `codex-utils-home-dir`, use
    `Config::log_dir` directly, and call
    `codex-sandboxing::system_bwrap_warning` without going through
    `legacy_core`.
    - Move shared `codex resume` hint formatting from `codex-core` into
    `codex-utils-cli`.
    - Update CLI and TUI call sites to use the shared CLI utility, and keep
    the resume-command behavior covered by tests in its new home.
    
    ## Verification
    
    - `cargo test -p codex-utils-cli`
    - `cargo test -p codex-utils-cli resume_command`
  • Refactor chatwidget orchestration into modules (phase 5) (#22537)
    ## 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, #22433 completed phase 3 by extracting protocol,
    replay, streaming, and tool lifecycle handling, and #22518 completed
    phase 4 by extracting settings, popups, and status surfaces.
    
    This PR is phase 5. It cleans up the remaining constructor and
    orchestration code now that the larger behavior domains have moved out,
    leaving `chatwidget.rs` much closer to the composition layer the cleanup
    was aiming for. This is once again a mechanical movement of existing
    functions. No functional changes.
    
    ## What Changed
    
    - Added focused modules for widget construction and initial wiring,
    session configuration flow, key/composer interaction routing, review
    popup orchestration, desktop notification coalescing, and render
    composition.
    - Moved the remaining constructor, session setup, interaction,
    notification, review picker, and rendering helpers out of
    `codex-rs/tui/src/chatwidget.rs`.
    - Preserved the existing startup/session behavior, keyboard handling,
    review picker flow, notification priority behavior, and render
    composition while shrinking the central widget module substantially.
    - Left `codex-rs/tui/src/chatwidget.rs` as the registration and
    composition surface for the extracted behavior modules.
    
    ## Cleanup Phases
    
    The five-phase cleanup plan from #22269 is:
    
    1. Phase 1: mechanical helper and state moves. Completed in #22269.

    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.

  • Refactor chatwidget settings surfaces into modules (phase 4) (#22518)
    ## Why
    
    `chatwidget.rs` is still carrying too many unrelated responsibilities in

    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

    - Kept active-cell grouping, transcript invalidation, interrupt

  • feat(tui): standardize picker navigation keys (#22347)
    ## 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:

    pre-existing
    `tests::fork_last_filters_latest_session_by_cwd_unless_show_all` stack
    overflow, which is unrelated to this branch.

    ## What Changed
    
    - Added `codex-rs/tui/src/chatwidget/input_flow.rs` for composer input

    - Added `codex-rs/tui/src/chatwidget/input_submission.rs` for
    user-message construction/submission, shell prompt submission,
    structured mention resolution, and blocked image draft restoration.
    - Added `codex-rs/tui/src/chatwidget/input_restore.rs` for
    initial-message submission, pending steer restoration after interrupts,
    and thread input snapshot/restore behavior.

  • Refactor chatwidget state into modules (#22269)
    ## Why
    
    `chatwidget.rs` is still carrying too many unrelated responsibilities in
    one file. After #21866 consolidated some of the state it tracks, this
    starts the next phase by moving coherent state/helper clusters out of
    the main module without changing behavior.
    
    This PR is intentionally mechanical: it only moves existing functions,
    structs, and helpers into focused modules so the boundaries are easier
    to review before the less mechanical refactors that should follow.
    
    ## What Changed
    
    - Moved user-message, composer, queue, pending steer, and merge/remap
    helpers into `codex-rs/tui/src/chatwidget/user_messages.rs`.
    - Added `codex-rs/tui/src/chatwidget/exec_state.rs` for unified exec
    bookkeeping helpers.
    - Added `codex-rs/tui/src/chatwidget/rate_limits.rs` for rate-limit
    warning, prompt, and error classification state.
    - Moved plugin list fetch and install auth-flow state into
    `codex-rs/tui/src/chatwidget/plugins.rs`.
    - Made a couple of test-only `VecDeque` imports explicit now that those
    tests no longer inherit the parent module import.
    
    ## Verification
    
    - `cargo test -p codex-tui` was run
    
    ## Follow-On Refactor Phases
    
    This PR is phase 1: mechanical helper and state moves. Planned follow-up
    PRs:
    
    - Phase 2: extract input and submission flow, including queued user

  • feat(tui): add ambient terminal pets (#21206)
    ## Why
    
    The Codex App has animated pets, but the TUI had no equivalent ambient
    companion surface. This brings that experience into terminal Codex while
    keeping the main chat flow usable: the pet should feel present, but it
    cannot cover transcript text, composer input, approvals, or picker
    content.
    
    The feature also needs to be terminal-aware. Different terminals support
    different image protocols, tmux can interfere with image rendering, and
    some users will want pets disabled entirely or anchored differently
    depending on their layout.

    ## What Changed
    
    - Add a TUI ambient pet renderer in `codex-rs/tui/src/pets/`.
    - Port the app-style pet animation states so the sprite changes with
    task status, waiting-for-input states, review/ready states, and
    failures.
    - Add `/pets` selection UI with a preview pane, loading state, built-in
    pet choices, and a first-row `Disable terminal pets` option.
    - Download built-in pet spritesheets on demand from the same public CDN
    path already used by Android, under
    `https://persistent.oaistatic.com/codex/pets/v1/...`, and cache them
    locally under `~/.codex/cache/tui-pets/`.
    - Keep custom pets local.
    - Add config support for pet selection, disabling pets, and choosing
    whether the pet follows the composer bottom or anchors to the terminal
    bottom.
    - Reserve layout space around the pet so transcript wrapping, live
    responses, and composer input do not render underneath the sprite.
    - Gate image rendering by terminal capability, disable image pets under
    tmux, and support both Kitty Graphics and SIXEL terminals.
    - Add redraw cleanup for terminal image artifacts, including sixel cell
    clearing.
    
    ## Current Scope
    
    - This is an initial TUI version of ambient pets, not full App parity.
    - It focuses on ambient sprite rendering, `/pets` selection, custom
    pets, terminal capability gating, and on-demand CDN-backed built-in
    assets.
    - The ambient text overlay is currently disabled, so the TUI renders the
    pet sprite without extra status text beside it.
    
    ## How to Test
    
    1. Start Codex TUI in a terminal with image support.
    2. Run `/pets`.
    3. Confirm the picker shows built-in pets plus custom pets, and the
    first item is `Disable terminal pets`.
    4. On a fresh `~/.codex/cache/tui-pets/`, move onto a built-in pet and
    confirm the first preview downloads the spritesheet from the shared
    Codex pets CDN and renders successfully.
    5. Move through the pet list and confirm subsequent built-in previews
    use the local cache.
    6. Select a pet, then send and receive messages. Confirm transcript and
    composer text wrap before the pet instead of rendering underneath the
    sprite.
    7. Change the pet anchor setting and confirm the pet can either follow
    the composer bottom or sit at the terminal bottom.
    8. Return to `/pets`, choose `Disable terminal pets`, and confirm the
    sprite disappears cleanly.
    
    Targeted tests:
    - `cargo test -p codex-tui ambient_pet_`
    - `cargo test -p codex-tui
    resize_reflow_wraps_transcript_early_when_pet_is_enabled`
    - `cargo insta pending-snapshots`
  • Unified mentions in TUI (#19068)
    This PR replaces the TUI’s file-only `@mention` popup with a unified
    mentions experience. Typing `@...` now searches across filesystem
    matches, installed plugins, and skills in one popup, with result types
    clearly labeled and selectable from the same flow.
    
    - Adds a unified `@mentions` popup that returns:
      - plugins
      - skills
      - files
      - directories
    
    - Adds search modes so users can narrow the popup without changing their
    query:
      - All Results _(default/same as Codex App)_
      - Filesystem Only
      - Plugins _(...and skills)_
    
    - Preserves existing insertion behavior:
      - selected file paths are inserted into the prompt
      - paths with spaces are quoted
      - image file selections still attach as images when possible
      - selecting a plugin or skill inserts the corresponding `$name`
    - the composer records the canonical mention binding, such as
    `plugin://...` or the skill path
    
    - Expanded `@mentions` rendering:
      - type tags for Plugin, Skill, File, and Dir
      - distinct plugin/filesystem colors
      - stable fixed-height layout (8 rows)
      - truncation behavior for narrow terminals
    
    Note:
    - The unified mentions popup does not display app connectors under
    `@mention` results for Codex App parity. Connector mentions remain
    available through the existing `$mention` path.

  • feat(tui): render responsive Markdown tables in TUI (#22052)
    ## Why
    
    The TUI currently treats Markdown tables as ordinary wrapped text, which
    makes table-heavy responses hard to read and brittle across narrow panes
    and terminal resizes.
    
    This change teaches the TUI to render Markdown tables responsively while
    preserving the raw Markdown source needed to re-render streamed and
    finalized transcript content after width changes. The goal is to keep
    tables legible during streaming, after resize, and once a turn has
    finished, without corrupting scrollback ordering.
    
    ## What Changed
    
    - add table detection and responsive table rendering in the Markdown
    renderer
    - render standard tables with Unicode box-drawing borders when the pane
    is wide enough
    - add a vertical readability fallback for constrained or dense tables so
    narrow panes still show each row clearly
    - keep links and `<br>` content inside table cells instead of leaking
    text outside the table
    - avoid table normalization inside fenced or indented code blocks
    - preserve raw streamed Markdown source and keep the active table as a
    mutable tail until finalization
    - consolidate finalized streamed content into source-backed transcript
    cells so post-resize re-rendering stays correct
    - add snapshot and targeted streaming/resize regression coverage for the
    new table behavior
    
    ## How to Test
    
    1. Start Codex TUI from this branch.
    2. Paste this exact prompt:
    `This is a session to test codex, no need to do any thinking, just end
    different markdown tables, with columns exploring different markdown
    contents, like links, bold italic, code, etc. Make them different sizes,
    some 30+ rows, some not and intertwine them with some paragraphs with
    complex formatting as well.`
    3. Confirm the response includes several Markdown tables mixed with
    richly formatted paragraphs.
    4. Confirm wide-enough tables render with box-drawing borders instead of
    plain wrapped pipe text.
    5. Resize the terminal narrower while the answer is still streaming and
    confirm the in-progress table stays coherent instead of duplicating
    headers or leaving broken scrollback behind.
    6. Resize again after the turn finishes and confirm the finalized
    transcript re-renders cleanly at the new width.
    7. In a narrow pane, verify dense tables fall back to the vertical
    per-row layout instead of producing unreadable wrapped columns.
    8. Also verify pipe-heavy fenced code blocks still render as code, not
    as tables.
    
    Targeted tests:
    - `cargo test -p codex-tui table_readability_fallback --no-fail-fast`
    - `cargo test -p codex-tui markdown_render --no-fail-fast`
    - `cargo test -p codex-tui streaming::controller --no-fail-fast`
    - `cargo test -p codex-tui table_resize_lifecycle --no-fail-fast`

  • Split ChatWidget state into focused modules (#21866)
    ## Summary
    
    `ChatWidget` has been carrying several independent domains in one large
    state bag: transcript bookkeeping, turn lifecycle, queued input, status
    surfaces, connectors, review mode, and protocol dispatch. That makes
    otherwise-local changes hard to reason about because unrelated fields
    and side effects live beside each other in `chatwidget.rs`.
    
    This is the first cleanup PR in a larger decomposition effort. It does
    not try to make `chatwidget.rs` small in one sweep; instead, it
    establishes focused state boundaries that later handler, popup,
    rendering, and effect-synchronization extractions can build on.
    
    This PR keeps `ChatWidget` as the composition layer while moving focused
    state into smaller `codex-tui` modules. The widget still owns effects
    that touch the bottom pane, app events, command submission, redraw
    scheduling, and terminal-title updates.
    
    ## Changes
    
    - Add focused state modules under `codex-rs/tui/src/chatwidget/` for
    input queues, turn lifecycle, transcript bookkeeping, status state,
    connectors, review mode, and app-server protocol dispatch.
    - Update `ChatWidget` to hold grouped state structs and route
    input/lifecycle/status operations through those focused helpers.
    - Move app-server notification dispatch into `chatwidget/protocol.rs`
    while leaving feature handlers and side effects on `ChatWidget`.
    - Replace the large manual `ChatWidget` test literal with the normal
    constructor plus narrow test overrides, so future state moves do not
    require every field to be restated in test setup.
    - Update existing tests to access the new grouped state or narrower
    helpers without changing snapshot behavior.
    
    ## Longer-term direction
    
    Follow-up PRs can continue shrinking `chatwidget.rs` by moving behavior,
    not just state, into focused modules:
    
    - Extract input/submission flow, turn/stream handling, and tool-cell
    lifecycles into domain modules that call the new state reducers.
    - Move popup/settings builders and rendering helpers out of the main
    widget file so `ChatWidget` stays focused on composition.
    - Reduce direct `BottomPane` mutation by applying domain-specific sync
    outputs at clearer boundaries.
  • [codex] request desktop attestation from app (#20619)
    ## Summary
    
    TL;DR: teaches `codex-rs` / app-server to request a desktop-provided
    attestation token and attach it as `x-oai-attestation` on the scoped
    ChatGPT Codex request paths.
    
    ![DeviceCheck attestation
    interface](https://raw.githubusercontent.com/openai/codex/dev/jm/devicecheck-diagram-assets/pr-assets/devicecheck-attestation-interface.png)
    
    ## Details
    
    This PR teaches the Codex app-server runtime how to request and attach
    an attestation token. It does not generate DeviceCheck tokens directly;
    instead, it relies on the connected desktop app to advertise that it can
    generate attestation and then asks that app for a fresh header value
    when needed.
    
    The flow is:
    
    1. The Codex desktop app connects to app-server.
    2. During `initialize`, the app can advertise that it supports
    `requestAttestation`.
    3. Before app-server calls selected ChatGPT Codex endpoints, it sends
    the internal server request `attestation/generate` to the app.
    4. app-server receives a pre-encoded header value back.
    5. app-server forwards that value as `x-oai-attestation` on the scoped
    outbound requests.
    
    The code in this repo is mostly protocol and runtime plumbing: it adds
    the app-server request/response shape, introduces an attestation
    provider in core, wires that provider into Responses / compaction /
    realtime setup paths, and covers the intended scoping with tests. The
    signed macOS DeviceCheck generation remains owned by the desktop app PR.

    First validated the signed desktop app boundary directly: launched a

    returned `v1.` attestation header, and validated the extracted
    DeviceCheck token with `personal/jm/verify_devicecheck_token.py` using
    bundle ID `com.openai.codex`. Apple returned `status_code: 200` and
    `is_ok: true`.
    
    Then ran the fuller app + app-server flow. The packaged `Codex.app`
    launched a current-branch app-server via `CODEX_CLI_PATH`, and a local
    MITM proxy intercepted outbound `chatgpt.com` traffic. The app-server
    requested `attestation/generate` from the real Electron app process, and
    the intercepted `/backend-api/codex/responses` traffic included
    `x-oai-attestation` on both routes:
    
    ```text
    GET  /backend-api/codex/responses  Upgrade: websocket  x-oai-attestation: present
    POST /backend-api/codex/responses  Upgrade: none       x-oai-attestation: present
    ```
    
    The captured header decoded to a DeviceCheck token that also validated
    with Apple for `com.openai.codex` (`status_code: 200`, `is_ok: true`,
    team `2DC432GLL2`).

  • Load configured environments from CODEX_HOME (#20667)
    ## Why
    
    The earlier PRs add stdio transport support and the config-backed
    environment provider, but the feature remains inert until normal Codex
    entrypoints construct `EnvironmentManager` with enough context to
    discover `CODEX_HOME/environments.toml`. This final stack PR activates
    the provider while preserving the legacy `CODEX_EXEC_SERVER_URL`
    fallback when no environments file exists.
    
    **Stack position:** this is PR 5 of 5. It is the product wiring PR that
    activates the configured environment provider added in PR 4.
    
    ## What Changed
    
    - Thread `codex_home` into `EnvironmentManagerArgs`.
    - Change `EnvironmentManager::new(...)` to load the provider from
    `CODEX_HOME`.
    - Preserve legacy behavior by falling back to
    `DefaultEnvironmentProvider::from_env()` when `environments.toml` is
    absent.
    - Make `environments.toml`-backed managers start new threads with all
    configured environments, default first, while keeping the legacy env-var
    path single-default.
    - Update the app-server, TUI, exec, MCP server, connector, prompt-debug,
    and thread-manager-sample callsites to pass `codex_home` and handle
    provider-loading errors.
    
    ## Self-Review Notes
    
    - The multi-environment startup path is intentionally tied to the
    `environments.toml` provider. Using `>1` configured environment as the
    only signal would also expand the legacy `CODEX_EXEC_SERVER_URL`
    provider because it keeps `local` addressable alongside `remote`.
    - The startup environment list is still derived inside
    `EnvironmentManager`; the provider only says whether its snapshot should
    start new threads with all configured environments.
    - The thread-manager sample was updated to pass the current
    `ThreadManager::new(...)` installation id argument so the stack compiles
    under Bazel.

  • [codex] Generalize service tier slash commands (#21745)
    ## Why
    
    `/fast` was wired as a one-off slash command even though model metadata
    now exposes service tiers as catalog data. That meant adding another
    tier, such as a slower/cheaper tier, would require more hardcoded TUI
    plumbing instead of letting the model catalog drive the available
    commands.
    
    This change makes service-tier commands data-driven: each advertised
    `service_tiers` entry becomes a `/name` command using the catalog
    description, while the request path sends the tier `id` only when the
    selected model supports it.
    
    ## What Changed
    
    - Removed the hardcoded `/fast` slash-command variant and introduced
    dynamic service-tier command items in the composer and command popup.
    - Added toggle behavior for service-tier commands: invoking `/name`
    selects that tier, and invoking it again clears the selection.
    - Preserved the existing Fast-mode keybinding/status affordances by
    resolving the current model tier whose name is `fast`, while still
    sending the tier request value such as `priority`.
    - Persisted service-tier selections as raw request strings so non-fast
    tiers can round-trip through config.
    - Updated the Bedrock catalog entry to advertise fast support through
    `service_tiers` with `id: "priority"` and `name: "fast"`.
    - Added defensive filtering in core so unsupported selected service
    tiers are omitted from `/responses` requests.
    
    ## Validation
    
    - Added/updated coverage for dynamic service-tier slash command lookup,
    popup descriptions, composer dispatch, TUI fast toggling, and
    unsupported-tier omission in core request construction.
    - Local tests were not run per request.

  • Show permissions and approval mode in the TUI status line (#21677)
    Fixes #21665.
    
    ## Why
    
    The TUI status line is the right place for compact, glanceable session
    state. The original request was motivated by the need to see the active
    permission posture without opening `/permissions` or `/status`,
    especially when switching between safer and more permissive modes during
    a session.
    
    This PR intentionally separates `permissions` from `approval-mode`
    instead of combining them into one status-line item. They answer related
    but different questions: `permissions` describes the active
    sandbox/profile shape, while `approval-mode` describes how command
    approvals are handled. Keeping them separate makes each item
    independently configurable and avoids long combined labels in an already
    space-constrained status line.
    
    The tradeoff is that users who want the full permission posture in the
    status line need to opt into both items. In exchange, users can show
    only the sandbox/profile label, only the approval behavior, or both, and
    named user-defined profiles remain concise. Non-standard permission
    shapes are rendered as `Custom permissions` rather than trying to
    squeeze detailed profile contents into the status line; `/status`
    remains the fuller explanatory surface.
    
    ## What changed
    
    - Added a configurable `permissions` status-line item.
    - Added a separate `approval-mode` status-line item, with `approval` as
    an alias.
    - Render standard permission states compactly as `Read Only`,
    `Workspace`, or `Full Access`.
    - Preserve user-defined permission profile names directly in the status
    line.
    - Render unnamed non-standard permission shapes as `Custom permissions`.
    - Refresh status surfaces when `/permissions` updates the permission
    profile, approval policy, or approval reviewer.
    - Updated status-line preview snapshot coverage for the new items.
    
    ## Verification
    
    - `cargo test -p codex-tui

  • [codex-analytics] plumb protocol-native review timing (#21434)
    ## Why
    
    We want terminal tool review analytics, but the reducer should not stamp
    review timing from its own wall clock.
    
    This PR plumbs review timing through the real protocol and app-server
    seams so downstream analytics can consume the emitter's timestamps
    directly. Guardian reviews keep their enriched `started_at` /
    `completed_at` analytics fields by deriving those legacy second-based
    values from the same protocol-native millisecond lifecycle timestamps,
    rather than sampling a separate analytics clock.
    
    ## What changed
    
    - add `started_at_ms` to user approval request payloads
    - add `started_at_ms` / `completed_at_ms` to guardian review
    notifications
    - preserve Guardian review `started_at` / `completed_at` enrichment from
    the protocol-native timing source
    - stamp typed `ServerResponse` analytics facts with app-server-observed
    `completed_at_ms`
    - thread the new timing fields through core, protocol, app-server, TUI,
    and analytics fixtures

    Fixes #21070.
    
    This is a small cleanup around model metadata handling for
    gateway/provider model names. It follows the report and proposed
    direction from @dkbush by keeping the fallback metadata warning useful
    without repeating it every turn, and by tightening the existing
    provider-prefix lookup path.
    
    - Track fallback metadata warning slugs in session state so each
    unresolved model warns once per session.
    - Keep warning emission outside the session-state lock and preserve the
    existing warning text.
    - Allow one-segment provider prefixes with hyphenated provider IDs,
    while preserving the multi-segment rejection behavior.
    - Add focused coverage for warning dedupe and hyphenated provider-prefix
    metadata matching.
    
    Testing:
    
    - Ran `just fmt`.
    - Ran `git diff --check`.
    - Added tests for the new warning dedupe and provider-prefix lookup
    behavior.
  • Move message history out of core (#21278)
    ## Why
    
    Message history was implemented inside `codex-core` and surfaced through
    core protocol ops and `SessionConfiguredEvent` fields even though the
    current consumer is TUI-local prompt recall. That made core own UI
    history persistence and exposed `history_log_id` / `history_entry_count`
    through surfaces that app-server and other clients do not need.
    
    This change moves message history persistence out of core and keeps the
    recall plumbing local to the TUI.
    
    ## What changed
    
    - Added a new `codex-message-history` crate for appending, looking up,
    trimming, and reading metadata from `history.jsonl`.
    - Removed core protocol history ops/events: `AddToHistory`,
    `GetHistoryEntryRequest`, and `GetHistoryEntryResponse`.
    - Removed `history_log_id` and `history_entry_count` from
    `SessionConfiguredEvent` and updated exec/MCP/test fixtures accordingly.
    - Updated the TUI to dispatch local app events for message-history
    append/lookup and keep its persistent-history metadata in TUI session
    state.

  • add turn items view to app-server turns (#21063)
    ## Why
    
    `Turn.items` currently overloads an empty array to mean either that no
    items exist or that the server intentionally did not load them for this
    response. That ambiguity blocks future lazy-loading work where clients
    need to distinguish unloaded, summary, and fully hydrated turn payloads.
    
    ## What changed
    
    - add a new `TurnItemsView` enum with `notLoaded`, `summary`, and `full`
    variants
    - add required `itemsView` metadata to app-server `Turn` payloads
    - mark reconstructed persisted history as `full` and live shell-style
    turn payloads as `notLoaded`
    - keep current `thread/turns/list` behavior unchanged and document that
    it still returns `full` turns today
    - regenerate the JSON and TypeScript protocol fixtures

  • feat(tui): add raw scrollback mode (#20819)
    ## Why
    
    Granular copy is particularly difficult with the current output. Part of
    it was solved with the introduction of the `/copy` command but when you
    only need to copy parts of a response, you still encounter some issues:
    
    - When you copy a paragraph, the result is a sequence of separate lines
    instead of one correctly joined paragraph.
    - When a word wraps, part of it stays on the original line and the rest
    appears at the start of the next line.
    - When you copy a long command, extra line breaks are often inserted,
    and command arguments can be split across multiple lines.
    
    
    https://github.com/user-attachments/assets/0ef85c84-9363-4aad-b43a-15fce062a443
    
    ## Solution
    
    Now that we own the scrollback and we re-create it when we resize, we
    have the opportunity of toggling between the raw text and the rich text
    we see today.
    
    - Add TUI raw scrollback mode with `tui.raw_output_mode`, `/raw
    [on|off]`, and the configurable `tui.keymap.global.toggle_raw_output`
    action.
    - Render transcript cells through rich/raw-aware paths so raw mode
    preserves source text and lets the terminal soft-wrap selection-friendly
    output.
    - Bind raw-mode toggle to `alt-r` by default, with the keybinding path
    toggling silently while `/raw` continues to emit confirmation messages.
    
    ## Related Issues
    
    Likely addressed by raw mode:
    
    - #12200: clean copy for multiline and soft-wrapped output. Raw mode
    removes Codex-inserted wrapping/indentation and lets the terminal
    soft-wrap logical lines.
    - #9252: command suggestions gain unwanted leading spaces when copied.
    Raw mode renders transcript text without the rich-mode left
    padding/gutter.
    - #8258: prompt output is hard to copy because of leading indentation.
    Raw mode renders user/source-backed transcript text without that
    decorative indentation.
    
    Partially or conditionally addressed:
    
    - #2880: copy/export message as Markdown. Raw mode exposes raw Markdown
    for terminal selection, but this PR does not add a dedicated
    export/copy-message command.
    - #19820: mouse drag selection + copy in the TUI. Raw mode improves
    terminal-native selection of output/history text, but this PR does not
    implement in-TUI mouse selection, highlighting, auto-copy, or composer
    selection.
    - #18979: copied content is divided into two parts. This should improve
    cases caused by Codex-inserted wraps/padding in rendered output; if the
    report is about pasting into the composer/input path, that remains
    outside this PR.

  • Validate /goal objective length in TUI (#20746)
    ## Why
    
    Long `/goal` definitions currently reach lower-level goal validation and
    can produce an opaque failure. This bug was reported by a user. Pasted
    instruction blocks are especially confusing because the composer can
    still contain a paste placeholder before expansion, which may otherwise
    fall into the generic prompt-size error path.
    
    There was also a related paste edge case where `/goal ` followed by a
    multiline block whose first pasted line was blank looked like a bare
    `/goal` command. That showed the goal usage/summary instead of setting
    the pasted objective.
    
    ## What Changed
    
    This adds TUI-side preflight validation for `/goal <objective>` using
    the shared `MAX_THREAD_GOAL_OBJECTIVE_CHARS` limit. Oversized typed,
    queued, and pasted goal objectives now fail locally with a goal-specific
    message that recommends putting longer instructions in a file and
    referencing that file from the goal.
    
    The TUI now also lets inline-argument slash commands consume later-line
    arguments before treating the first line as a bare command, so `/goal `
    followed by blank lines and then objective text sets the goal instead of
    opening the bare `/goal` flow.
    
    ## Manual Testing
    
    1. Start the TUI with goals enabled and an active session.
    2. Submit `/goal ` followed by exactly 4,000 objective characters. It
    should continue through the normal goal-setting path.
    3. Submit `/goal ` followed by 4,001 objective characters. It should not
    set a goal, and should show `Goal objective is too long: 4,001
    characters. Limit: 4,000 characters.` followed by the guidance to put
    longer instructions in a file and reference that file from the goal.
    4. Type `/goal `, paste a large block that becomes a `[Pasted Content
    ... chars]` placeholder, then submit. It should validate the expanded
    pasted text and show the goal-specific file guidance rather than the
    generic prompt-size error.
    5. Type `/goal `, paste a multiline block whose first line is blank,
    then submit. It should set the objective from the non-blank pasted
    content instead of showing `Usage: /goal <objective>` or the bare goal
    summary.
    6. While a turn is running, queue an oversized `/goal` command. When the
    queue drains, it should show the same goal-specific error and should not
    emit a goal-setting request.
  • [codex] Add unsandboxed process exec API (#19040)
    ## Why
    
    App-server clients sometimes need argv-based local process execution
    while sandbox policy is controlled outside Codex. Those environments can
    reject sandbox-disabling paths before a command ever starts, even when
    the caller intentionally wants unsandboxed execution.
    
    This PR adds a distinct `process/*` API for that use case instead of
    extending `command/exec` with another sandbox-disabling shape. Keeping
    the new surface separate also makes the future removal of `command/exec`
    simpler: clients that need explicit process lifecycle control can move
    to the newer handle-based API without depending on `command/exec`
    business logic.
    
    ## What changed
    
    - Added v2 process lifecycle methods: `process/spawn`,
    `process/writeStdin`, `process/resizePty`, and `process/kill`.
    - Added process notifications: `process/outputDelta` for streamed
    stdout/stderr chunks and `process/exited` for final exit status and
    buffered output.
    - Made `process/spawn` intentionally unsandboxed and omitted
    sandbox-selection fields such as `sandboxPolicy` and
    `permissionProfile`.
    - Added client-supplied, connection-scoped `processHandle` values for
    follow-up control requests and notification routing.
    - Supported cwd, environment overrides, PTY mode and size, stdin
    streaming, stdout/stderr streaming, per-stream output caps, and timeout
    controls.
    - Killed active process sessions when the originating app-server
    connection closes.
    - Wired the implementation through the modular `request_processors/`
    app-server layout, with process-handle request serialization for
    follow-up control calls.
    - Updated generated JSON/TypeScript schema fixtures and documented the
    new API in `codex-rs/app-server/README.md`.
    - Added v2 app-server integration coverage in
    `codex-rs/app-server/tests/suite/v2/process_exec.rs` for spawn
    acknowledgement before exit, buffered output caps, and process
    termination.

  • feat(tui): add PR summary statusline items (#20892)
    ## Why?
    
    The Codex App already exposes branch and PR context in its
    branch-details UI. This brings the same context into the CLI footer as
    opt-in statusline items, so users can choose the extra signal without
    making the default footer busier.
    
    ## What?
    
    Add optional `pull-request-number` and `branch-changes` items to the
    configurable TUI status line.
    
    - `pull-request-number` shows the open PR for the current checkout and
    renders as a clickable terminal hyperlink when OSC 8 links are
    supported.
    - `branch-changes` shows committed additions/deletions against the
    repository default branch, or `No changes` when the branch has no
    committed diff.
    
    <img width="1257" height="261" alt="CleanShot 2026-05-03 at 20 44 15"
    src="https://github.com/user-attachments/assets/10b4380b-c3e9-4729-9ee1-3f742068fa47"
    />
    
    ## Architecture
    
    This follows the same client/app-server split as the Codex App: the TUI
    owns presentation, caching, and optional rendering, while
    workspace-sensitive `git` and `gh` discovery runs through app-server.
    
    The new TUI-local `workspace_command` layer sends bounded,
    non-interactive `command/exec` requests to the active app-server. That
    makes the implementation remote-friendly: the TUI does not decide
    whether commands run in an embedded local workspace or a remote
    workspace, and it does not bypass app-server sandbox or permission
    policy.
    
    The branch summary logic stays internal to `codex-tui` because this PR
    only needs TUI statusline behavior. The command boundary is still
    isolated behind `WorkspaceCommandExecutor`, so the lookup code can be
    lifted or reused later without changing statusline rendering.
    
    ## How?
    
    - Add a TUI `WorkspaceCommandExecutor` abstraction backed by app-server
    `command/exec`.
    - Add branch summary probes for:
      - current branch name,
      - open PR metadata,
      - committed branch diff stats against the default branch.
    - Prefer remote-tracking default branch refs for diff stats, avoiding
    stale or absent local `main` branches.
    - Resolve PRs with `gh pr view` first, then fall back to
    commit-associated PR lookup across parent/fork repos.
    - Add `/statusline` picker entries, preview values, rendering, and OSC 8
    clickable PR links.
    - Keep all probes best-effort so missing `git`, missing `gh`, auth
    failures, or non-git directories hide optional items instead of
    surfacing footer errors.
    
    ## Validation
    
    - `cargo test -p codex-tui branch_summary -- --nocapture`
    - Snapshot coverage for the `/statusline` preview/setup rendering paths
    - Hyperlink rendering coverage for clickable PR statusline cells
  • tui: retire /approvals and rename /autoreview to /approve (#21034)
    ## Why
    
    The TUI currently exposes overlapping command names for the same
    permissions flow: `/permissions` and the older `/approvals` alias. It
    also uses `/autoreview` for the manual retry flow, even though the
    action users take there is approving one denied auto-review request.
    
    This change makes the command surface consistent with the hard rebrand:
    - `/permissions` is the only command for permission settings.
    - `/approve` is the command for approving a recent auto-review denial.
    
    ## What changed
    
    - Removed the legacy `/approvals` slash command and its dispatch path.
    - Kept `/permissions` as the single permissions command shown and
    accepted by the TUI.
    - Renamed the auto-review denial command from `/autoreview` to
    `/approve`.
    - Updated nearby comments so they refer to `/permissions` rather than
    the retired `/approvals` name.
    
    ## Verification
    
    - Updated the slash-command unit test to assert that `AutoReview` now
    renders and parses as `approve`.
  • Clear live hook rows when turns finalize (#20674)
    # Why
    
    When a user interrupts a turn while a hook is still running, the normal
    turn status is cleared but the separate live hook row can remain visible
    as `Running` because the TUI may never receive a matching
    `HookCompleted` event before cancellation. Once the turn itself is
    finalized, that turn-scoped live state should not remain on screen.
    
    # What
    
    - clear any still-live `active_hook_cell` during turn finalization
    - add a regression snapshot covering an interrupted turn with a visible
    `PreToolUse` hook row
    
    # Testing
    
    - `cargo test -p codex-tui interrupted_turn_clears_visible_running_hook`
    - attempted `cargo test -p codex-tui` (currently aborts on unrelated
    existing stack overflow in

  • /plugins: add marketplace upgrade flow (#20478)
    This PR adds marketplace upgrade to the `/plugins` menu so users can
    update configured marketplaces. It adds a `Ctrl+U` shortcut on eligible
    marketplace tabs, a loading state, and the app-server request flow
    needed to perform `marketplace/upgrade`. After a successful upgrade, the
    TUI refreshes plugin data, plugin mentions, and user config so updated
    marketplace contents show up across the menu and other plugin surfaces.
    It also preserves the current marketplace tab on no-op and failure paths
    and surfaces backend error details directly in the TUI.
    
    - Add a `Ctrl+U` upgrade option for user-configured marketplace tabs in
    `/plugins`
    - Show the upgrade footer hint only on upgradeable marketplace tabs
    - Show a loading state during `marketplace/upgrade`
    - Surface already-up-to-date and per-marketplace failure results from
    the backend
    - Refresh plugin data, plugin mentions, and user config after successful
    upgrades
    - Add tests and snapshot updates for the shortcut flow, loading state,
    and failure messaging
    
    Steps to test:
    1. Add a `/plugin` marketplace to Codex TUI.
    2. Open `/plugins`, move to that marketplace tab, and confirm the footer
    shows `Ctrl+U` to upgrade.
    3. Press `Ctrl+U` and confirm the popup switches into an upgrade loading
    state.
    4. When the request finishes, confirm you see the expected result:
    updated marketplace contents on success, an already-up-to-date message
    on no-op, or backend error details on failure. On no-op or failure,
    confirm the popup stays on the same marketplace tab.
  • Add /ide context support to the TUI (#20294)
    ## Why
    
    Users have asked for a `/ide` command in the TUI so Codex can use the
    active IDE session for live context such as the current file, open tabs,
    and selected ranges. We already support a similar feature in the Codex
    desktop app, so bringing it to the TUI makes sense.
    
    One subtle compatibility constraint is that the injected prompt wrapper
    and transcript stripping should match the desktop app and IDE extension.
    By using the same `## My request for Codex:` delimiter and hiding the
    injected context from transcript rendering the same way, threads created
    in the TUI render correctly in desktop and IDE surfaces, and threads
    created there replay correctly in the TUI, even when IDE context was
    included.
    
    Addresses https://github.com/openai/codex/issues/13834.
    
    ## What changed
    ### Summary
    This PR consists of four four pieces:
    1. An IPC client that uses a socket (Mac/Linux) or named pipe (Windows)
    to talk to the IDE Extension
    2. Logic that establishes the IPC connection and requests IDE context
    (open files, selection) on demand
    3. Logic that injects this context into the user prompt (using the same
    technique as the desktop app) and hides the added context when rendering
    the prompt in the TUI transcript
    4. A new slash command for enabling/disabling this mode and text within
    the footer to indicate when it's enabled
    
    ### Details
    - Added `/ide [on|off|status]` to the TUI, with bare `/ide` toggling IDE
    context on or off.
    - Added a Rust IDE context client that connects to the local Codex IDE
    IPC route as a client and requests context from the IDE extension flow.
    - Injected IDE context using the same prompt delimiter and
    transcript-stripping convention as the desktop app and IDE extension so
    shared threads render consistently across surfaces.
    - Added an `IDE context` status-line indicator while the feature is
    active and cleared it when enabling or fetching context fails.
    - Added handling for multiple selection ranges, oversized selections,
    interleaved IPC messages, and transient reconnect timing after quick
    toggles.
    
    ## Verification
    
    Did extensive manual testing in addition to running automated unit and
    regression tests.
    
    To test:
    
    - Launch VS Code (or Cursor) with the IDE extension.
    - Open one or more files in the IDE and select a range of text within
    one of them.
    - Start the TUI.
    - Ask the agent which files you have open in your IDE, and it should say
    that it does not know.
    - Enable `/ide` mode; note that `IDE context` appears in the lower
    right.
    - Ask the agent what files you have open in your IDE and what text is
    selected.
