  • tui: split remaining composer draft and footer state (#22656)
    ## 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`
  • tui/exec: show effective workspace roots in summaries (#22612)
    ## 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
  • app-server: use permission ids and runtime workspace roots (#22611)
    ## 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.

  • TUI: split history cells into focused modules (#22704)
    ## Why
    
    `codex-rs/tui/src/history_cell.rs` had become the dumping ground for
    transcript rendering: the shared trait, common helpers, and the concrete
    cells for messages, plans, MCP/search, notices, patches, approvals,
    session chrome, and separators all lived together. That made small
    transcript changes require reopening a very large file and made
    ownership less obvious.
    
    ## What changed
    
    - Replaced the monolithic `history_cell.rs` with a `history_cell/`
    module tree organized by concern.
    - Kept the existing `crate::history_cell::*` surface stable through
    re-exports in `history_cell/mod.rs`.
    - Moved the existing render coverage into `history_cell/tests.rs`.
    
    ## Reviewer notes
    
    - This PR is intentionally mechanical in mature — existing code and
    tests moving into files that match their concern.
    - The snapshot files under `codex-rs/tui/src/history_cell/snapshots/`
    moved with the extracted test module. `insta` resolves these unnamed
    snapshots relative to the source file that declares them, so this is
    path churn only; snapshot contents were not updated.
    - The small non-mechanical seam edits are limited to split fallout:
    sibling-module visibility for shared cell containers, moving
    approval-specific exec-snippet helpers beside approvals, fixing the
    separator module path, and keeping a couple of existing test helpers
    reachable after extraction.
  • Prevent Esc from dismissing or rewinding /side (#22710)
    Addresses #22599
    
    ## 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`.
  • tui: recover local state db startup failures (#22734)
    ## Why
    
    #22580 made app-server startup fail when the local SQLite state database
    cannot be initialized. Embedded/local TUI startup still continued on the
    permissive path, which left the CLI inconsistent and could hide a real
    startup problem behind unrelated UI. This brings local TUI startup onto
    the same fail-closed behavior while keeping recovery humane for the two
    failure modes we are seeing in practice: damaged database files and
    startup stalls caused by another process holding the database write
    lock.
    
    ## What changed
    
    - Embedded TUI startup now uses `state_db::try_init(...)` and returns a
    typed `LocalStateDbStartupError` that preserves the affected database
    path plus the underlying failure detail.
    - CLI startup handles that failure before entering the interactive TUI:
    - lock-contention failures tell users to quit other Codex processes and
    try again
    - failures consistent with a broken local database offer a safe repair
    that backs up Codex-owned SQLite files, rebuilds local database files,
    and retries startup once
    - declined or unsuccessful repairs print concise guidance plus technical
    details
    - Shared startup error plumbing lives in `tui/src/startup_error.rs`,
    while CLI recovery policy and focused recovery tests live in
    `cli/src/state_db_recovery.rs`.
    
    ## Verification
    
    - `cargo test -p codex-tui
    embedded_state_db_failure_is_typed_for_cli_recovery`
    - `cargo test -p codex-cli state_db_recovery`
    - Manually held an exclusive SQLite lock on `state_5.sqlite` and
    confirmed the CLI shows lock-specific guidance without offering repair.
    - Manually exercised the repair path with a deliberately invalid
    `sqlite_home` and confirmed it backs up the blocking path and resumes
    startup.
  • permissions: resolve profile identity with constraints (#22683)
    ## Why
    
    This PR is the invariant-cleanup layer that follows the workspace-roots
    base merged in [#22610](https://github.com/openai/codex/pull/22610).
    
    #22610 adds `[permissions.<id>.workspace_roots]` and keeps runtime
    workspace roots separate from the raw permission profile, but its
    in-memory representation is intentionally transitional: `Permissions`
    still carries the selected profile identity next to a constrained
    `PermissionProfile`. That makes APIs such as
    `set_constrained_permission_profile_with_active_profile()` fragile
    because the id and value only mean the right thing when every caller
    keeps them in sync.
    
    This PR introduces a single resolved profile state so profile identity,
    `extends`, the profile value, and profile-declared workspace roots
    travel together. The next PR,
    [#22611](https://github.com/openai/codex/pull/22611), builds on this by
    changing the app-server turn API to select permission profiles by id
    plus runtime workspace roots.
    
    ## Stack Context
    
    - #22610, now merged: adds profile-declared `workspace_roots`, runtime
    workspace roots, and `:workspace_roots` materialization.
    - This PR: replaces the parallel active-profile/profile-value fields
    with `PermissionProfileState`.
    - #22611: switches app-server turn updates toward profile ids plus
    runtime workspace roots.
    - #22612: updates TUI/exec summaries to show the effective workspace
    roots.
    
    Keeping this separate from #22611 is deliberate: reviewers can validate
    the internal state invariant before reviewing the app-server protocol
    migration.
    
    ## What Changed
    
    - Added `ResolvedPermissionProfile::{Legacy, BuiltIn, Named}` and
    `PermissionProfileState`.
    - Typed built-in profile ids with `BuiltInPermissionProfileId`.
    - Moved selected profile identity and profile-declared workspace roots
    into the resolved state.
    - Replaced `Permissions` parallel profile fields with one
    `permission_profile_state`.
    - Removed `set_constrained_permission_profile_with_active_profile()`
    from session sync paths.
    - Kept trusted session replay/`SessionConfigured` compatibility through
    explicit session snapshot helpers.
    - Updated session configuration, MCP initialization, app-server, exec,
    TUI, and guardian call sites to consume `&PermissionProfile` directly.
    
    ## Review Guide
    
    Start with `codex-rs/core/src/config/resolved_permission_profile.rs`; it
    is the new invariant boundary. Then review
    `codex-rs/core/src/config/mod.rs` to see how config loading records
    active profile identity and profile workspace roots. The remaining
    call-site changes are mostly mechanical fallout from
    `Permissions::permission_profile()` returning `&PermissionProfile`
    instead of `&Constrained<PermissionProfile>`.
    
    ## Verification
    
    The existing config/session coverage now constructs and asserts through
    `PermissionProfileState`. The workspace-root config test also asserts
    that profile-declared roots are preserved in the resolved state, which
    is the behavior #22611 relies on when runtime roots become mutable
    through the app-server API.

  • permissions: support workspace roots in profiles (#22610)
    ## Why
    
    This is the configuration/model half of the alternative permissions
    migration we discussed as a comparison point for
    [#22401](https://github.com/openai/codex/pull/22401) and
    [#22402](https://github.com/openai/codex/pull/22402).
    
    The old `workspace-write` model mixes three concerns that we want to
    keep separate:
    - reusable profile rules that should stay immutable once selected
    - user/runtime workspace roots from `cwd`, `--add-dir`, and legacy
    workspace-write config
    - internal Codex writable roots such as memories, which should not be
    shown as user workspace roots
    
    This PR gives permission profiles first-class `workspace_roots` so users
    can opt multiple repositories into the same `:workspace_roots` rules
    without using broad absolute-path write grants. It also starts
    separating the raw selected profile from the effective runtime profile
    by making `Permissions` expose explicit accessors instead of public
    mutable fields.
    
    A representative `config.toml` looks like this:
    
    ```toml
    default_permissions = "dev"
    
    [permissions.dev.workspace_roots]
    "~/code/openai" = true
    "~/code/developers-website" = true
    
    [permissions.dev.filesystem.":workspace_roots"]
    "." = "write"
    ".codex" = "read"
    ".git" = "read"
    ".vscode" = "read"
    ```
    
    If Codex starts in `~/code/codex` with that profile selected, the
    effective workspace-root set becomes:
    - `~/code/codex` from the runtime `cwd`
    - `~/code/openai` from the profile
    - `~/code/developers-website` from the profile
    
    The `:workspace_roots` rules are materialized across each root, so
    `.git`, `.codex`, and `.vscode` stay scoped the same way everywhere.
    Runtime additions such as `--add-dir` can still layer on later stack
    entries without mutating the selected profile.
    
    ## Stack Shape
    
    This PR intentionally stops before the profile-identity cleanup in
    [#22683](https://github.com/openai/codex/pull/22683) so the base review
    stays focused on config loading, workspace-root materialization, and
    compatibility with legacy `workspace-write`.
    
    The representation in this PR is therefore transitional: `Permissions`
    carries enough state to distinguish the raw constrained profile from the
    effective runtime profile, and there are still call sites that must keep
    the active profile identity and constrained profile value in sync. The
    follow-up PR replaces that with a single resolved profile state
    (`ResolvedPermissionProfile` / `PermissionProfileState`) that keeps the
    profile id, immutable `PermissionProfile`, and profile-declared
    workspace roots together. That follow-up removes APIs such as
    `set_constrained_permission_profile_with_active_profile()` where
    separate arguments could drift out of sync.
    
    Downstream PRs then build on this base to switch app-server turn updates
    to profile ids plus runtime workspace roots and to finish the
    user-visible summary behavior. Reviewers should judge this PR as the
    workspace-roots foundation, not as the final in-memory shape of selected
    permission profiles.
    
    ## Review Guide
    
    Suggested review order:
    
    1. Start with `codex-rs/core/src/config/mod.rs`.
    This is the main shape change in the base slice. `Permissions` now
    stores a private raw `Constrained<PermissionProfile>` plus runtime
    `workspace_roots`. Callers use `permission_profile()` when they need the
    raw constrained value and `effective_permission_profile()` when they
    need a materialized runtime profile. As noted above,
    [#22683](https://github.com/openai/codex/pull/22683) replaces this
    transitional shape with a resolved profile state that keeps identity and
    profile data together.
    
    2. Review `codex-rs/config/src/permissions_toml.rs` and
    `codex-rs/core/src/config/permissions.rs`.
    These add `[permissions.<id>.workspace_roots]`, resolve enabled entries
    relative to the policy cwd, and keep `:workspace_roots` deny-read glob
    patterns symbolic until the actual roots are known.
    
    3. Review `codex-rs/protocol/src/permissions.rs` and
    `codex-rs/protocol/src/models.rs`.
    These add the policy/profile materialization helpers that expand exact
    `:workspace_roots` entries and scoped deny-read globs over every
    workspace root. This is also where `ActivePermissionProfileModification`
    is removed from the core model.
    
    4. Review the legacy bridge in
    `Config::load_from_base_config_with_overrides` and
    `Config::set_legacy_sandbox_policy`.
    This is where legacy `workspace-write` roots become runtime workspace
    roots, while Codex internal writable roots stay internal and do not
    appear as user-facing workspace roots.
    
    5. Then skim downstream call sites.
    The interesting pattern is raw-vs-effective access: state/proxy/bwrap
    paths keep the raw constrained profile, while execution, summaries, and
    user-visible status use the effective profile and workspace-root list.
    
    ## What Changed
    
    - added `[permissions.<id>.workspace_roots]` to the config model and
    schema
    - added runtime `workspace_roots` state to `Config`/`Permissions` and
    `ConfigOverrides`
    - made `Permissions` profile fields private and replaced direct mutation
    with accessors/setters
    - added `PermissionProfile` and `FileSystemSandboxPolicy` helpers for
    materializing `:workspace_roots` exact paths and deny-read globs across
    all roots
    - moved legacy additional writable roots into runtime workspace-root
    state instead of active profile modifications
    - removed `ActivePermissionProfileModification` and its app-server
    protocol/schema export
    - updated sandbox/status summary paths so internal writable roots are
    not reported as user workspace roots
    
    ## Verification Strategy
    
    The targeted tests cover the behavior at the layers where regressions
    are most likely:
    - `codex-rs/core/src/config/config_tests.rs` verifies config loading,
    legacy workspace-root seeding, effective profile materialization, and
    memory-root handling.
    - `codex-rs/core/src/config/permissions_tests.rs` verifies profile
    `workspace_roots` parsing and `:workspace_roots` scoped/glob
    compilation.
    - `codex-rs/protocol/src/permissions.rs` unit tests verify exact and
    glob materialization over multiple workspace roots.
    - `codex-rs/tui/src/status/tests.rs` and
    `codex-rs/utils/sandbox-summary/src/sandbox_summary.rs` verify the
    user-facing summaries show effective workspace roots and hide internal
    writes.
    
    I also ran `cargo check --tests` locally after the latest stack refresh
    to catch cross-crate API breakage from the private-field/accessor
    changes.

  • Fix /review mode MCP startup render issue (#21624)
    This change fixes the case where the UI can sit on _"Starting MCP
    servers"_ even though the review work is already running or has already
    completed.
    
    - MCP startup status header is visible when a `/review` turn starts with
    enabled MCP server startups
    - Restore the underlying _Working..._ status after MCP startup completes
    or fails
    - Add regression coverage for overlapping startup/turn flows and status
    restoration
    
    _De-scoped from a broader thread-scoped MCP status change that would
    have made it easier to route MCP startup statuses to the appropriate
    thread (parent vs. review). These changes address the UI regression
    without requiring more significant changes across app-server & core._
    
    Fixes #18792.
  • 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`
  • [codex] Support multiple forced ChatGPT workspaces (#18161)
    ## Summary
    
    This change lets `forced_chatgpt_workspace_id` accept multiple workspace
    IDs instead of a single value.
    
    It keeps the existing config key name, adds backward-compatible parsing
    for a single string in `config.toml`, and normalizes the setting into an
    allowed workspace list across login enforcement, app-server config
    surfaces, and local ChatGPT auth helpers.
    
    ## Why
    
    Workspace-restricted deployments may need to allow more than one ChatGPT
    workspace without dropping the guardrail entirely.
    
    ## Server-side impact
    
    Codex's local server and app-server protocol needed changes because they
    previously assumed a single workspace ID. The local login flow now
    matches the auth backend interface by sending the allowed workspace list
    as a single comma-separated `allowed_workspace_id` query parameter.
    
    ## Validation
    
    This was tested with:
    
    - A single workspace config
    - With multi-workspace configs
    - With multiple workspaces in the config
    - The user only being a part of a subset of them
    
    All were successful.
    
    Automated coverage:
    
    - `cargo test -p codex-login`
    - `cargo test -p codex-app-server-protocol`
    - `cargo test -p codex-tui local_chatgpt_auth`
    - `cargo test --locked -p codex-app-server
    login_account_chatgpt_includes_forced_workspace_allowlist_query_param`
  • fix(tui): render network approval history by target (#22229)
    ## Why
    
    Network approval prompts are rendered without a command string on the
    app-server path. After the user approves one of those prompts, the TUI
    history cell previously fell back to command-oriented copy and produced
    malformed lines such as:
    
    ```text
    You approved codex to run  every time this session
    ```
    
    That hid the network target the user actually approved and left a
    visibly broken transcript entry.
    
    ## What changed
    
    - Preserve the approval subject as either a command or a network target
    when recording TUI approval decisions.
    - Render target-aware history copy for network approval outcomes:
      - approve once
      - approve for the current session
      - cancel
    - Include the approval protocol and preserve the managed-proxy
    `network-access` target when present, including non-default ports such
    as `https://example.com:8443`.
    - Fall back to formatting the network approval context as
    `protocol://host` when no generated target command is available.
    - Keep ordinary command approval history, Guardian approval history, and
    persisted network-rule history behavior unchanged.
    - Add focused regression coverage and snapshots for the three
    network-history cases.
    
    ## How to Test
    
    1. Start Codex in a flow that triggers a network approval prompt.
    2. Approve network access only for the current conversation.
    3. Confirm the transcript records the approved network target, for
    example:
    - `You approved codex network access to https://example.com:8443 every
    time this session`
    4. Trigger the prompt again and verify the one-time approval and cancel
    paths also record target-specific history text instead of an empty
    command gap.
    
    Targeted automated coverage:
    - `cargo test -p codex-tui network_exec_approval_history`
    
    ## Additional verification
    
    - `cargo insta pending-snapshots`
    - `git diff --check`
    - `just fix -p codex-tui`
    - `just argument-comment-lint`
    
    ## Known unrelated local test noise
    
    A full `cargo test -p codex-tui` run still hits a pre-existing stack
    overflow outside this change:
    - `tests::fork_last_filters_latest_session_by_cwd_unless_show_all`
    aborts with a stack overflow
  • tui: split composer attachment and popup state (#22581)
    ## Why
    
    `ChatComposer` currently owns text editing alongside attachment
    bookkeeping and popup lifecycle state, while `BottomPane` still triggers
    a couple of popup resyncs after composer methods that already do that
    work internally. That blurs the ownership boundary and makes the
    composer harder to simplify safely.
    
    This PR is part 1 of a two-part cleanup. It peels off the composer state
    that can move cleanly on its own, so the follow-up can tackle the
    heavier draft/editing boundary without mixing every concern into one
    diff.
    
    ## What changed
    
    - Move local and remote image bookkeeping, placeholder relabeling, and
    remote-image keyboard selection into `AttachmentState`.
    - Move active-popup and popup-dismissal/query bookkeeping into
    `PopupState`.
    - Update composer and history-search paths to use those state owners
    directly.
    - Remove redundant `BottomPane` popup synchronization after paste
    handling and `insert_str`.
    
    ## Part 2
    
    The follow-up PR will finish the cleanup around the remaining composer
    boundary: split out the draft/editing-oriented state and footer/status
    presentation concerns that still live in `ChatComposer`, then revisit
    the leftover `BottomPane` pass-throughs once those ownership lines are
    explicit. The goal is for `ChatComposer` to coordinate a few focused
    collaborators instead of continuing to be the landing zone for every
    input-path concern.
    
    ## Verification
    
    Did manual smoke tests.
  • permissions: canonicalize workspace_roots and danger-full-access names (#22624)
    ## Why
    
    This is a small precursor to the larger permissions-migration work. Both
    the comparison stack in
    [#22401](https://github.com/openai/codex/pull/22401) /
    [#22402](https://github.com/openai/codex/pull/22402) and the alternate
    stack in [#22610](https://github.com/openai/codex/pull/22610) /
    [#22611](https://github.com/openai/codex/pull/22611) /
    [#22612](https://github.com/openai/codex/pull/22612) are easier to
    review if the terminology is already settled underneath them.
    
    Because `:project_roots` and `:danger-no-sandbox` have not shipped as
    stable user-facing surface area, carrying them forward as aliases would
    just add more migration logic to the later stacks. This PR removes that
    ambiguity now so the follow-on work can rely on one spelling for each
    built-in concept.
    
    ## What Changed
    
    - renamed the config-facing special filesystem key from `:project_roots`
    to `:workspace_roots`
    - dropped unpublished `:project_roots` parsing support in
    `core/src/config/permissions.rs`, so new config only recognizes
    `:workspace_roots`
    - renamed the built-in full-access permission profile id from
    `:danger-no-sandbox` to `:danger-full-access`
    - dropped unpublished `:danger-no-sandbox` support entirely, including
    the old active-profile canonicalization path, and added explicit
    rejection coverage for the legacy id
    - introduced shared built-in permission-profile id constants in
    `codex-rs/protocol/src/models.rs`
    - updated `core`, `app-server`, and `tui` call sites that special-case
    built-in profiles to use the shared constants and canonical ids
    - updated tests and the Linux sandbox README to use `:workspace_roots` /
    `:danger-full-access`
    
    ## Verification
    
    I focused verification on the three places this rename can regress:
    config parsing, active-profile identity surfaced back out of `core`, and
    user/server call sites that special-case built-in profiles.

  • feat: add layered --profile-v2 config files (#17141)
    ## Why
    
    `--profile-v2 <name>` gives launchers and runtime entry points a named
    profile config without making each profile duplicate the base user
    config. The base `$CODEX_HOME/config.toml` still loads first, then
    `$CODEX_HOME/<name>.config.toml` layers above it and becomes the active
    writable user config for that session.
    
    That keeps shared defaults, plugin/MCP setup, and managed/user
    constraints in one place while letting a named profile override only the
    pieces that need to differ.
    
    ## What Changed
    
    - Added the shared `--profile-v2 <name>` runtime option with validated
    plain names, now represented by `ProfileV2Name`.
    - Extended config layer state so the base user config and selected
    profile config are both `User` layers; APIs expose the active user layer
    and merged effective user config.
    - Threaded profile selection through runtime entry points: `codex`,
    `codex exec`, `codex review`, `codex resume`, `codex fork`, and `codex
    debug prompt-input`.
    - Made user-facing config writes go to the selected profile file when
    active, including TUI/settings persistence, app-server config writes,
    and MCP/app tool approval persistence.
    - Made plugin, marketplace, MCP, hooks, and config reload paths read
    from the merged user config so base and profile layers both participate.
    - Updated app-server config layer schemas to mark profile-backed user
    layers.
    
    ## Limits
    
    `--profile-v2` is still rejected for config-management subcommands such
    as feature, MCP, and marketplace edits. Those paths remain tied to the
    base `config.toml` until they have explicit profile-selection semantics.
    
    Some adjacent background writes may still update base or global state
    rather than the selected profile:
    
    - marketplace auto-upgrade metadata
    - automatic MCP dependency installs from skills
    - remote plugin sync or uninstall config edits
    - personality migration marker/default writes
    
    ## Verification
    
    Added targeted coverage for profile name validation, layer
    ordering/merging, selected-profile writes, app-server config writes,
    session hot reload, plugin config merging, hooks/config fixture updates,
    and MCP/app approval persistence.

  • Defer startup NUX impressions until startup succeeds (#22587)
    ## Why
    
    This is a follow-up to #22573. This problem was surfaced in a code
    review comment that I missed before merging the previous PR.
    
    Fresh-session startup could prepare a model-availability NUX before
    `app_server.start_thread(&config)` completed. If thread startup then
    failed, the TUI never rendered the tooltip, but
    `prepare_startup_tooltip_override(...)` had already persisted one of the
    limited impressions.
    
    ## What Changed
    
    - Move startup tooltip preparation inside the fresh-thread startup
    branch, after `start_thread(...)` succeeds.
    - Keep resume/fork paths unchanged.
    - Remove the now-redundant
    `should_prepare_startup_tooltip_override(...)` helper and its gate test.
  • Simplify TUI startup test coverage (#22573)
    ## Why
    
    The TUI startup test surface had drifted into expensive, brittle
    coverage:
    
    - `tui/tests/suite/no_panic_on_startup.rs` was already ignored as flaky
    while still spawning a PTY to exercise malformed exec-policy rules.
    - `tui/tests/suite/model_availability_nux.rs` used a seeded session,
    cursor-query spoofing, and repeated interrupts to verify a narrow
    resume-path invariant.
    - `app/tests.rs` had started accumulating unrelated startup and summary
    coverage in one flat module even after the surrounding app code was
    split into feature modules.
    
    This keeps those behaviors covered while making the tests cheaper to
    understand and less likely to rot. It also preserves the malformed-rules
    regression from #8803 without requiring a terminal orchestration test.
    
    ## What changed
    
    - Replaced the malformed `rules` startup PTY case with a direct
    exec-policy loader regression:
    
    [`rules_path_file_returns_read_dir_error`](https://github.com/openai/codex/blob/21b6b5622f18b8cac0ea41fd083b3106778d9ffc/codex-rs/core/src/exec_policy_tests.rs#L264-L284)
    - Made the existing fresh-session-only startup tooltip behavior explicit
    with
    
    [`should_prepare_startup_tooltip_override`](https://github.com/openai/codex/blob/21b6b5622f18b8cac0ea41fd083b3106778d9ffc/codex-rs/tui/src/app/thread_routing.rs#L1272-L1279),
    then added focused coverage for the resume/fork gate and the persisted
    NUX counter.
    - Split startup and session-summary coverage out of
    `tui/src/app/tests.rs` into dedicated modules so the test layout better
    mirrors the current app architecture.
    - Converted one single-message goal validation snapshot into semantic
    assertions where layout was not the behavior under test.
    - Removed the two PTY-heavy suite files that the narrower tests now
    supersede.
    
    ## Verification
    
    - `cargo test -p codex-core rules_path_file_returns_read_dir_error`
    - `cargo test -p codex-tui startup_`
    - `cargo test -p codex-tui session_summary_`
    - `cargo test -p codex-tui

  • 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.
    2. Phase 2: extract input and submission flow, including queued user
    messages, shell prompt submission, pending steer restoration, and thread
    input snapshot/restore behavior. Completed in #22407.
    3. Phase 3: extract protocol, replay, streaming, and tool lifecycle
    handling, while preserving active-cell grouping, transcript
    invalidation, interrupt deferral, and final-message separator behavior.
    Completed in #22433.
    4. Phase 4: extract settings, popups, and status surfaces, including
    model/reasoning/collaboration/personality popups, permission prompts,
    rate-limit UI, and connectors helpers. Completed in #22518.
    5. Phase 5: clean up the remaining constructor and orchestration code
    once the larger behavior domains have moved out, leaving `chatwidget.rs`
    as the composition layer. This PR.
    
    ## Verification
    
    - `cargo check -p codex-tui`
    - `cargo test -p codex-tui chatwidget::tests::popups_and_settings`
    - `cargo test -p codex-tui chatwidget::tests::plan_mode`
    - `cargo test -p codex-tui chatwidget::tests::review_mode`
    - `cargo test -p codex-tui chatwidget::tests::status_and_layout`
    
    `cargo test -p codex-tui` also compiles and begins running, but aborts
    in the unchanged app-side test
    `app::tests::discard_side_thread_keeps_local_state_when_server_close_fails`
    with the same reproducible stack overflow noted in phase 4.
  • Remove resurrected /collab slash command (#22535)
    ## Summary
    `/collab` was intentionally removed in
    [#12012](https://github.com/openai/codex/pull/12012), but the
    TUI/app-server migration accidentally brought that slash-command path
    back. This restores the earlier product decision so the TUI no longer
    advertises or dispatches `/collab`. This command was redundant because
    it did the same thing as `/plan` but in a less-intuitive way.
    
    ## What Changed
    - Remove `SlashCommand::Collab` from the TUI slash-command surface.
    - Delete the picker and app-event plumbing that only existed to service
    `/collab`.
    - Remove obsolete TUI test coverage for the deleted picker flow.
  • feat(cli): add codex doctor diagnostics (#22336)
    ## Why
    
    Users and support need a single command that captures the local Codex
    runtime, configuration, auth, terminal, network, and state shape without
    asking the user to know which diagnostic depth to choose first. `codex
    doctor` now runs the useful checks by default and makes the detailed
    human output the default because the command is usually run when someone
    already needs context.
    
    The command also targets concrete support failure modes we have seen
    while iterating on the design:
    
    - update-target mismatches like #21956, where the installed package
    manager target can differ from the running executable
    - terminal and multiplexer issues that depend on `TERM`, tmux/zellij
    state, color handling, and TTY metadata
    - provider-specific HTTP/WebSocket connectivity, including ChatGPT
    WebSocket handshakes and API-key/provider endpoint reachability
    - local state/log SQLite integrity problems and large rollout
    directories
    - feedback reports that need an attached, redacted diagnostic snapshot
    without asking the user to run a second command
    
    ## What Changed
    
    - Adds `codex doctor` as a grouped CLI diagnostic report with default
    detailed output and `--summary` for the compact view.
    - Adds stable report sections for Environment, Configuration, Updates,
    Connectivity, and Background Server, plus a top Notes block that
    promotes anomalies such as available updates, large rollout directories,
    optional MCP issues, and mixed auth signals.
    - Adds runtime provenance, install consistency, bundled/system search
    readiness, terminal/multiplexer metadata, `config.toml` parse status,
    auth mode details, sandbox details, feature flag summaries, update
    cache/latest-version state, app-server daemon state, SQLite integrity
    checks, rollout statistics, and provider-aware network diagnostics.
    - Adds ChatGPT WebSocket diagnostics that report the negotiated HTTP
    upgrade as `HTTP 101 Switching Protocols` and include timeout, DNS,
    auth, and provider context in detailed output.
    - Makes reachability provider-aware: API-key OpenAI setups check the API
    endpoint, ChatGPT auth checks the ChatGPT path, and custom/AWS/local
    providers check configured HTTP endpoints when available.
    - Adds structured, redacted JSON output where `checks` is keyed by check
    id and `details` is a key/value object for support tooling.
    - Integrates doctor with feedback uploads by attaching a best-effort
    `codex-doctor-report.json` report and adding derived Sentry tags for
    overall status and failing/warning checks.
    - Updates the TUI feedback consent copy so users can see that the doctor
    report is included when logs/diagnostics are uploaded.
    - Updates the CLI bug issue template to ask reporters for `codex doctor
    --json` and render pasted reports as JSON.
    
    ## Example Output
    
    The examples below are sanitized from local smoke runs with `--no-color`
    so the structure is reviewable in plain text.

    ## How to Test
    
    1. Run `cargo run --bin codex -- doctor --no-color`.
    2. Confirm the detailed report is the default and includes promoted
    Notes, grouped sections, terminal details, state DB integrity, rollout
    stats, provider reachability, WebSocket diagnostics, and app-server
    status.
    3. Run `cargo run --bin codex -- doctor --summary --no-color`.
    4. Confirm the compact view keeps the same sections and summary counts
    but omits detailed key/value rows.
    5. Run `cargo run --bin codex -- doctor --json`.
    6. Confirm the output is redacted JSON, `checks` is an object keyed by
    check id, and each check's `details` is a key/value object.
    7. Preview the CLI bug issue template and confirm the `Codex doctor
    report` field appears after the terminal field, asks for `codex doctor
    --json`, and renders pasted output as JSON.
    8. Start a feedback flow that includes logs.
    9. Confirm the upload consent copy lists `codex-doctor-report.json`
    alongside the log attachments.

  • [codex] Fix TUI wrapping for external borrowed slices (#21235)
    Fixes #20587, reported by @noeljackson.
    
    This prevents the TUI wrapping code from panicking when `textwrap`
    returns a borrowed slice that does not point into the original source
    text. The fix follows the direction proposed by @misrtjakub in the issue
    comment: validate the borrowed slice pointer range first, and fall back
    to the existing owned-line mapper when the slice is external.
    
    - Guards borrowed wrapped slices before converting pointer offsets into
    byte ranges.
    - Reuses the existing owned-line range recovery path for external
    borrowed slices.
    - Adds coverage for rejecting borrowed slices outside the source text.
    
    End-user testing steps:
    - Start Codex in TUI mode under a PTY wrapper that can inject stdin
    after startup.
    - Inject `\x1b[200~test message\x1b[201~\r` after the TUI is ready.
    - Confirm Codex does not panic and the pasted text is handled normally.
    
    Local validation:
    - `cargo test -p codex-tui wrapping::tests::`
    - `cargo test -p codex-tui -- --skip
    status::tests::status_permissions_full_disk_managed_with_network_is_danger_full_access
    --skip
    status::tests::status_permissions_full_disk_managed_without_network_is_external_sandbox`
  • Use plugin/list to get list of plugins for mentions (#22375)
    This switches TUI plugin mentions to use app-server `plugin/list` for
    plugin inventory and metadata instead of `PluginManager`, while keeping
    the same mention-eligibility filters as before.
    
    Same filters as before:
    - Only plugins in the current config / cwd scope.
    - Only installed and enabled plugins.
    - Only plugins that actually expose a capability, meaning at least one
    skill, MCP server, or app connector.
    - Uses `plugin/list` for the mention names/descriptions
  • Refactor chatwidget settings surfaces into modules (phase 4) (#22518)
    ## Why
    
    `chatwidget.rs` is still carrying too many unrelated responsibilities in
    one file. #22269 started a five-phase cleanup to move coherent behavior
    domains into focused modules while keeping `chatwidget.rs` as the
    composition layer. #22407 completed phase 2 by extracting input and
    submission flow, and #22433 completed phase 3 by extracting protocol,
    replay, streaming, and tool lifecycle handling.
    
    This PR is phase 4. It keeps moving high-churn UI coordination out of
    the central widget by extracting settings, popups, and status surfaces
    without changing the visible behavior those flows already provide. This
    is once again a mechanical movement of existing functions. No functional
    changes.
    
    ## What Changed
    
    - Added focused modules for runtime settings/model coordination,
    model/reasoning/collaboration popups,
    settings/personality/theme/audio/experimental popups, permission
    prompts, status setup/output controls, and Windows sandbox prompt flows.
    - Moved the remaining rate-limit nudge/status helpers and connectors
    popup/loading/update helpers into their existing focused modules.
    - Preserved the existing picker flows, approval behavior, status/title
    setup previews, rate-limit notices, and connectors/app list behavior
    while shrinking `chatwidget.rs` back toward orchestration.
    - Left `codex-rs/tui/src/chatwidget.rs` as the registration and
    composition surface for these extracted behaviors.
    
    ## Cleanup Phases
    
    The five-phase cleanup plan from #22269 is:
    
    1. Phase 1: mechanical helper and state moves. Completed in #22269.
    2. Phase 2: extract input and submission flow, including queued user
    messages, shell prompt submission, pending steer restoration, and thread
    input snapshot/restore behavior. Completed in #22407.
    3. Phase 3: extract protocol, replay, streaming, and tool lifecycle
    handling, while preserving active-cell grouping, transcript
    invalidation, interrupt deferral, and final-message separator behavior.
    Completed in #22433.
    4. Phase 4: extract settings, popups, and status surfaces, including
    model/reasoning/collaboration/personality popups, permission prompts,
    rate-limit UI, and connectors helpers. This PR.
    5. Phase 5: clean up the remaining constructor and orchestration code
    once the larger behavior domains have moved out, leaving `chatwidget.rs`
    as the composition layer.
    
    ## Verification
    
    - `cargo check -p codex-tui`
    - `cargo test -p codex-tui chatwidget::tests::permissions`
    - `cargo test -p codex-tui chatwidget::tests::status_surface_previews`
    - `cargo test -p codex-tui chatwidget::tests::popups_and_settings`
    - `cargo test -p codex-tui chatwidget::tests::status_and_layout`
    
    `cargo test -p codex-tui` also compiles and begins running, but aborts
    in the unchanged app-side test
    `app::tests::discard_side_thread_keeps_local_state_when_server_close_fails`
    with a reproducible stack overflow.
  • config: add strict config parsing (#20559)
    ## Why
    
    Codex intentionally ignores unknown `config.toml` fields by default so
    older and newer config files keep working across versions. That leniency
    also makes typo detection hard because misspelled or misplaced keys
    disappear silently.
    
    This change adds an opt-in strict config mode so users and tooling can
    fail fast on unrecognized config fields without changing the default
    permissive behavior.
    
    This feature is possible because `serde_ignored` exposes the exact
    signal Codex needs: it lets Codex run ordinary Serde deserialization
    while recording fields Serde would otherwise ignore. That avoids
    requiring `#[serde(deny_unknown_fields)]` across every config type and
    keeps strict validation opt-in around the existing config model.
    
    ## What Changed
    
    ### Added strict config validation
    
    - Added `serde_ignored`-based validation for `ConfigToml` in
    `codex-rs/config/src/strict_config.rs`.
    - Combined `serde_ignored` with `serde_path_to_error` so strict mode
    preserves typed config error paths while also collecting fields Serde
    would otherwise ignore.
    - Added strict-mode validation for unknown `[features]` keys, including
    keys that would otherwise be accepted by `FeaturesToml`'s flattened
    boolean map.
    - Kept typed config errors ahead of ignored-field reporting, so
    malformed known fields are reported before unknown-field diagnostics.
    - Added source-range diagnostics for top-level and nested unknown config
    fields, including non-file managed preference source names.
    
    ### Kept parsing single-pass per source
    
    - Reworked file and managed-config loading so strict validation reuses
    the already parsed `TomlValue` for that source.
    - For actual config files and managed config strings, the loader now
    reads once, parses once, and validates that same parsed value instead of
    deserializing multiple times.
    - Validated `-c` / `--config` override layers with the same
    base-directory context used for normal relative-path resolution, so
    unknown override keys are still reported when another override contains
    a relative path.
    
    ### Scoped `--strict-config` to config-heavy entry points
    
    - Added support for `--strict-config` on the main config-loading entry
    points where it is most useful:
      - `codex`
      - `codex resume`
      - `codex fork`
      - `codex exec`
      - `codex review`
      - `codex mcp-server`
      - `codex app-server` when running the server itself
      - the standalone `codex-app-server` binary
      - the standalone `codex-exec` binary
    - Commands outside that set now reject `--strict-config` early with
    targeted errors instead of accepting it everywhere through shared CLI
    plumbing.
    - `codex app-server` subcommands such as `proxy`, `daemon`, and
    `generate-*` are intentionally excluded from the first rollout.
    - When app-server strict mode sees invalid config, app-server exits with
    the config error instead of logging a warning and continuing with
    defaults.
    - Introduced a dedicated `ReviewCommand` wrapper in `codex-rs/cli`
    instead of extending shared `ReviewArgs`, so `--strict-config` stays on
    the outer config-loading command surface and does not become part of the
    reusable review payload used by `codex exec review`.
    
    ### Coverage
    
    - Added tests for top-level and nested unknown config fields, unknown
    `[features]` keys, typed-error precedence, source-location reporting,
    and non-file managed preference source names.
    - Added CLI coverage showing invalid `--enable`, invalid `--disable`,
    and unknown `-c` overrides still error when `--strict-config` is
    present, including compound-looking feature names such as
    `multi_agent_v2.subagent_usage_hint_text`.
    - Added integration coverage showing both `codex app-server
    --strict-config` and standalone `codex-app-server --strict-config` exit
    with an error for unknown config fields instead of starting with
    fallback defaults.
    - Added coverage showing unsupported command surfaces reject
    `--strict-config` with explicit errors.
    
    ## Example Usage
    
    Run Codex with strict config validation enabled:
    
    ```shell
    codex --strict-config
    ```
    
    Strict config mode is also available on the supported config-heavy
    subcommands:
    
    ```shell
    codex --strict-config exec "explain this repository"
    codex review --strict-config --uncommitted
    codex mcp-server --strict-config
    codex app-server --strict-config --listen off
    codex-app-server --strict-config --listen off
    ```
    
    For example, if `~/.codex/config.toml` contains a typo in a key name:
    
    ```toml
    model = "gpt-5"
    approval_polic = "on-request"
    ```
    
    then `codex --strict-config` reports the misspelled key instead of
    silently ignoring it. The path is shortened to `~` here for readability:
    
    ```text
    $ codex --strict-config
    Error loading config.toml:
    ~/.codex/config.toml:2:1: unknown configuration field `approval_polic`
      |
    2 | approval_polic = "on-request"
      | ^^^^^^^^^^^^^^
    ```
    
    Without `--strict-config`, Codex keeps the existing permissive behavior
    and ignores the unknown key.
    
    Strict config mode also validates ad-hoc `-c` / `--config` overrides:
    
    ```text
    $ codex --strict-config -c foo=bar
    Error: unknown configuration field `foo` in -c/--config override
    
    $ codex --strict-config -c features.foo=true
    Error: unknown configuration field `features.foo` in -c/--config override
    ```
    
    Invalid feature toggles are rejected too, including values that look
    like nested config paths:
    
    ```text
    $ codex --strict-config --enable does_not_exist
    Error: Unknown feature flag: does_not_exist
    
    $ codex --strict-config --disable does_not_exist
    Error: Unknown feature flag: does_not_exist
    
    $ codex --strict-config --enable multi_agent_v2.subagent_usage_hint_text
    Error: Unknown feature flag: multi_agent_v2.subagent_usage_hint_text
    ```
    
    Unsupported commands reject the flag explicitly:
    
    ```text
    $ codex --strict-config cloud list
    Error: `--strict-config` is not supported for `codex cloud`
    ```
    
    ## Verification
    
    The `codex-cli` `strict_config` tests cover invalid `--enable`, invalid
    `--disable`, the compound `multi_agent_v2.subagent_usage_hint_text`
    case, unknown `-c` overrides, app-server strict startup failure through
    `codex app-server`, and rejection for unsupported commands such as
    `codex cloud`, `codex mcp`, `codex remote-control`, and `codex
    app-server proxy`.
    
    The config and config-loader tests cover unknown top-level fields,
    unknown nested fields, unknown `[features]` keys, source-location
    reporting, non-file managed config sources, and `-c` validation for keys
    such as `features.foo`.
    
    The app-server test suite covers standalone `codex-app-server
    --strict-config` startup failure for an unknown config field.
    
    ## Documentation
    
    The Codex CLI docs on developers.openai.com/codex should mention
    `--strict-config` as an opt-in validation mode for supported
    config-heavy entry points once this ships.
  • Refactor chatwidget protocol flows into modules (phase 3) (#22433)
    ## Why
    
    `chatwidget.rs` is still carrying too many unrelated responsibilities in
    one file. #22269 started a five-phase cleanup to move coherent behavior
    domains into focused modules while keeping `chatwidget.rs` as the
    composition layer. #22407 completed phase 2 by extracting input and
    submission flow.
    
    This PR is phase 3. It keeps moving high-churn event handling out of the
    central widget by extracting protocol, replay, streaming, and tool
    lifecycle handling without changing the visible behavior those flows
    already provide. This is once again just a mechanical movement of
    existing functions. No functional changes.
    
    ## What Changed
    
    - Added focused modules for protocol request dispatch, replay rendering,
    assistant/plan/reasoning streaming, turn runtime bookkeeping, hook
    lifecycle handling, command lifecycle handling, tool lifecycle
    rendering, and interactive tool request prompts.
    - Kept active-cell grouping, transcript invalidation, interrupt
    deferral, and final-message separator behavior in the same flows, just
    moved into smaller files.
    - Added module header comments to the new files so the ownership
    boundaries are explicit.
    - Left `codex-rs/tui/src/chatwidget.rs` as the registration and
    orchestration surface for these extracted behaviors.
    
    ## Cleanup Phases
    
    The five-phase cleanup plan from #22269 is:
    
    1. Phase 1: mechanical helper and state moves. Completed in #22269.
    2. Phase 2: extract input and submission flow, including queued user
    messages, shell prompt submission, pending steer restoration, and thread
    input snapshot/restore behavior. Completed in #22407.
    3. Phase 3: extract protocol, replay, streaming, and tool lifecycle
    handling, while preserving active-cell grouping, transcript
    invalidation, interrupt deferral, and final-message separator behavior.
    This PR.
    4. Phase 4: extract settings, popups, and status surfaces, including
    model/reasoning/collaboration/personality popups, permission prompts,
    rate-limit UI, and connectors helpers.
    5. Phase 5: clean up the remaining constructor and orchestration code
    once the larger behavior domains have moved out, leaving `chatwidget.rs`
    as the composition layer.
  • 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:
    
    - `cargo test -p codex-tui keymap::tests::`
    - `cargo test -p codex-tui keymap_setup::tests::`
    - `cargo test -p codex-tui horizontal_list_keys`
    - `cargo test -p codex-tui page_and_jump_navigation_use_list_keymap`
    - `cargo test -p codex-tui ctrl_h_l_move_provider_selection`

    - `cargo test -p codex-tui
    switching_tabs_changes_visible_items_and_clears_search`
    - `cargo test -p codex-tui toggle_sort_key_reloads_with_new_sort`
    
    Also ran `just write-config-schema`, `just fmt`, `just fix -p
    codex-tui`, `just argument-comment-lint`, and `git diff --check`.
    
    Note: `cargo test -p codex-tui` was attempted and still aborts in the
    pre-existing
    `tests::fork_last_filters_latest_session_by_cwd_unless_show_all` stack
    overflow, which is unrelated to this branch.
  • feat(tui): remove Zellij TUI workarounds (#22214)
    ## Why
    
    We added Zellij-specific TUI workarounds because older Zellij behavior
    did not work with Codex's normal terminal model:
    
    - #8555 made `tui.alternate_screen = "auto"` disable alternate screen in
    Zellij so transcript history stayed available.
    - #16578 avoided scroll-region operations in Zellij by emitting raw
    newlines and using a separate composer styling path.
    
    This PR removes both workarounds because the latest Zellij release
    tested locally (`zellij 0.44.1`) works correctly with Codex's standard
    TUI behavior: normal alternate-screen handling, redraw, and history
    insertion.
    
    ## What Changed
    
    - Removed the `InsertHistoryMode::Zellij` path and the Zellij-only
    newline scrollback insertion behavior.
    - Removed cached `is_zellij` state from the TUI and composer.
    - Removed Zellij-specific composer styling, the helper snapshot, and the
    `TerminalInfo::is_zellij()` convenience method that only served this
    workaround.
    - Changed `tui.alternate_screen = "auto"` to use alternate screen for
    Zellij too; `--no-alt-screen` and `tui.alternate_screen = "never"` still
    preserve the inline mode escape hatch.
    - Updated the generated config schema description for
    `tui.alternate_screen`.
    
    ## How to Test
    
    Manual smoke path used with `zellij 0.44.1`:
    
    1. Build and run this branch inside a Zellij `0.44.1` session with
    default config.
    2. Start Codex normally and produce enough assistant/tool output to
    create scrollback.
    3. Confirm the transcript remains readable, the composer renders
    normally, and scrolling through terminal history works.
    4. Resize the Zellij pane while output exists and confirm the TUI
    redraws without duplicated, missing, or stale rows.
    5. Compare with `--no-alt-screen` or `-c tui.alternate_screen=never` if
    you want to verify the inline fallback still works.
    
    Targeted tests:
    - `just write-config-schema`
    - `just fmt`
    - `just fix -p codex-tui`
    - `cargo test -p codex-terminal-detection`
    - `cargo test -p codex-tui alternate_screen_auto_uses_alt_screen`
    
    Attempted but did not complete locally:
    - `cargo test -p codex-tui` built and ran the new test successfully,
    then failed later on unrelated local failures in
    `status_permissions_full_disk_managed_*` and a stack overflow in
    `tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.
    
    ## Documentation
    
    No developers.openai.com Codex documentation update is needed for this
    revert.
  • add --dangerously-bypass-hook-trust CLI flag (#21768)
    # Why
    
    Hook trust happens through the TUI in `/hooks` so it can block
    non-interactive use cases. This flag will allow users that are using
    codex headlessly to bypass hooks when they want to.
    
    # What
    
    This adds one invocation-scoped escape hatch.
    
    - the CLI flag sets a runtime-only `bypass_hook_trust` override; there
    is no durable `config.toml` setting
    - hook discovery still respects normal enablement, so explicitly
    disabled hooks remain disabled
    - we show a `--dangerously-bypass-hook-trust is enabled. Enabled hooks
    may run without review for this invocation.` message on startup so
    accidental use is visible in both interactive and exec flows
    
    This keeps “enabled” and “trusted” as separate concepts in the normal
    path, while giving CI/E2E callers a stable way to opt into the
    exceptional path when they already control the hook set.
  • Refactor chatwidget input flow into modules (#22407)
    ## Why
    
    `chatwidget.rs` is still carrying too many unrelated responsibilities in
    one file. #22269 started a five-phase effort to move coherent behavior
    domains into focused modules while keeping `chatwidget.rs` as the
    composition layer.
    
    This PR is phase 2 of that plan. It extracts the input and submission
    flow as a mechanical move before the later protocol, popup/status, and
    constructor/orchestration phases.
    
    ## What Changed
    
    - Added `codex-rs/tui/src/chatwidget/input_flow.rs` for composer input
    results, queued user-message draining, pending-input previews, and
    mode-specific submission entry points.
    - 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.
    - Registered the new modules and removed the moved `ChatWidget` impl
    methods from `codex-rs/tui/src/chatwidget.rs`.
    
    ## Follow-On Refactor Phases
    
    The five-phase plan from #22269 is:
    
    - Phase 1: mechanical helper and state moves. Completed in #22269.
    - Phase 2: extract input and submission flow, including queued user
    messages, shell prompt submission, pending steer restoration, and thread
    input snapshot/restore behavior. This PR.
    - Phase 3: extract protocol, replay, streaming, and tool lifecycle
    handling, while preserving active-cell grouping, transcript
    invalidation, interrupt deferral, and final-message separator behavior.
    - Phase 4: extract settings, popups, and status surfaces, including
    model/reasoning/collaboration/personality popups, permission prompts,
    rate-limit UI, and connectors helpers.
    - Phase 5: clean up the remaining constructor and orchestration code
    once the larger behavior domains have moved out, leaving `chatwidget.rs`
    as the composition layer.
  • Add support for UDS in codex --remote (#22414)
    ## Why
    
    Added support for UDS connections in `codex --remote`.
    
    TUI also now connects to local app-server using UDS by default if it is
    running and set to listen to UDS connection.
    
    ## What Changed
    
    - Introduced `RemoteAppServerEndpoint` with `WebSocket` and `UnixSocket`
    variants.
    - Reused the existing JSON-RPC-over-WebSocket protocol over either a TCP
    WebSocket stream or a UDS stream.
    - Updated `codex --remote` to accept `ws://host:port`,
    `wss://host:port`, `unix://`, and `unix://PATH`.
    - Kept `--remote-auth-token-env` restricted to `wss://` and loopback
    `ws://` remotes.
    - Added a fast TUI startup probe for the default daemon socket, falling
    back to the embedded app server when the daemon is absent or
    unresponsive.
    
    ## Verification
    
    - Manually verified that the updated remote flow works.
    - Added coverage for UDS remote round trips, WebSocket auth headers,
    auth-token transport policy, remote address parsing, and missing-daemon
    fallback.
    - Ran focused remote test coverage locally.
  • Add allow_managed_hooks_only hook requirement (#20319)
    ## Why
    
    Enterprise-managed hook policy needs a narrow way to require Codex to
    ignore user-controlled lifecycle hooks without adopting the broader
    trust-precedence model from earlier hook work. This keeps the policy
    anchored in `requirements.toml`, so admins can opt into managed hooks
    only while normal `config.toml` files cannot enable the restriction
    themselves.
    
    ## What changed
    
    - Added `allow_managed_hooks_only` to the requirements data flow and
    preserved explicit `false` values.
    - Also adds it to /debug-config
    - Marked MDM, system, and legacy managed config layers as managed for
    hook discovery.
    - Updated hook discovery so `allow_managed_hooks_only = true`:
      - keeps managed requirements hooks and managed config-layer hooks,
    - skips user/project/session `hooks.json` and `[hooks]` entries with
    concise startup warnings,
      - skips current unmanaged plugin hooks,
    - ignores any `allow_managed_hooks_only` key placed in ordinary
    `config.toml` layers.
  • feat: Expose plugin versions and gate plugin sharing (#22397)
    - Adds localVersion to plugin summaries and remoteVersion to share
    context, including generated API schemas.
    - Hydrates local and remote plugin versions from manifests and remote
    release metadata.
    - Adds default-on plugin_sharing gate for shared-with-me listing and
    plugin/share/save, with disabled-path errors
        and focused coverage.
  • 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
    messages, shell prompt submission, pending steer restoration, and thread
    input snapshot/restore behavior.
    - Phase 3: extract protocol, replay, streaming, and tool lifecycle
    handling, while preserving active-cell grouping, transcript
    invalidation, interrupt deferral, and final-message separator behavior.
    - Phase 4: extract settings, popups, and status surfaces, including
    model/reasoning/collaboration/personality popups, permission prompts,
    rate-limit UI, and connectors helpers.
    - Phase 5: clean up the remaining constructor and orchestration code
    once the larger behavior domains have moved out, leaving `chatwidget.rs`
    as the composition layer.
  • [codex] Remove workspace owner usage nudge gate (#20509)
    ## Summary
    - make workspace owner nudge handling unconditional in the TUI now that
    it is fully rolled out
    - keep `workspace_owner_usage_nudge` as a removed no-op compatibility
    flag so old configs/app overrides remain accepted during rollout
    - remove flag-disabled test setup
    
    ## Companion PR
    - https://github.com/openai/openai/pull/876351 removes the Codex Apps
    Statsig rollout gate override after this change is available to the
    app/runtime path
    
    ## Validation
    - `just write-config-schema`
    - `just fmt`
    - `cargo test -p codex-features`
    - `cargo test -p codex-tui status_and_layout`
  • test(tui): relax configured pet load timeout (#22392)
    ## Why
    
    Windows CI has been timing out in
    `configured_pet_load_is_deferred_until_after_construction` while waiting
    for the deferred configured-pet load event.
    
    The test still needs to prove construction returns before the pet image
    is available, but the background load slices the built-in pet
    spritesheet into frame cache files. That work can exceed the old 2
    second deadline on slower or more contended CI machines.
    
    ## What Changed
    
    - Increased the test wait for `ConfiguredPetLoaded` from 2 seconds to 30
    seconds.
    - Kept the post-construction assertion intact so the test still verifies
    that the pet is not loaded synchronously during `ChatWidget`
    construction.
    
    ## How to Test
    
    Targeted tests:
    - `cargo test -p codex-tui
    configured_pet_load_is_deferred_until_after_construction`
    - `just argument-comment-lint`
    
    Additional check:
    - `cargo test -p codex-tui` was run, but the broader crate suite did not
    complete successfully due to unrelated existing failures:
    -
    `status::tests::status_permissions_full_disk_managed_without_network_is_external_sandbox`
    -
    `status::tests::status_permissions_full_disk_managed_with_network_is_danger_full_access`
    - later abort in
    `tests::fork_last_filters_latest_session_by_cwd_unless_show_all` from
    stack overflow
  • code-mode: carry nested tool kind through runtime (#22377)
    ## Why
    
    Code mode only used nested spec lookup at execution time to rediscover
    whether a nested tool should be invoked as a function tool or a freeform
    tool.
    
    That information is already present in the enabled tool metadata that
    code mode builds to expose `tools.*` and `ALL_TOOLS`, so re-looking it
    up from the router was redundant and kept execution coupled to a
    separate spec lookup path.
    
    ## What Changed
    
    - thread `CodeModeToolKind` through the code-mode runtime `ToolCall`
    event and `CodeModeNestedToolCall`
    - emit the nested tool kind directly from the V8 callback using the
    already-enabled tool metadata
    - build nested tool payloads from the propagated kind instead of calling
    `find_spec`
    - remove the now-unused `find_spec` plumbing from the router and
    parallel runtime helpers
    - add unit coverage for function vs freeform payload shaping and update
    affected router tests
    
    ## Testing
    
    - `cargo test -p codex-code-mode`
    - `cargo test -p codex-core code_mode::tests`
    - `cargo test -p codex-core
    extension_tool_bundles_are_model_visible_and_dispatchable`
    - `cargo test -p codex-core
    model_visible_specs_filter_deferred_dynamic_tools`
  • 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.

    </table>
    
    ## 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`
  • feat: Normalize remote plugin summary identities. (#22265)
    Makes plugin summaries use config-style plugin@marketplace IDs while
    exposing backend remote IDs separately as remotePluginId.
    
    Also fix the consistency issue of REMOTE_SHARED_WITH_ME_MARKETPLACE_NAME
  • Add Windows hook command overrides (#22159)
    # Why
    
    Managed hook configs need a shared cross-platform shape without making
    the existing `command` field polymorphic. The common case is still one
    command string, with Windows needing a different entrypoint only when
    the runtime is actually Windows.
    
    Keeping `command` as the portable/default path and adding an optional
    Windows override keeps the config easier to read, preserves the existing
    scalar shape for non-Windows users, and avoids forcing every caller into
    a `{ unix, windows }` object when only one platform needs special
    handling.
    
    # What
    
    - Add optional `command_windows` / `commandWindows` alongside the
    existing hook `command` field.
    - Resolve `command_windows` only on Windows during hook discovery; other
    platforms continue to use `command` unchanged.
    - Keep trust hashing aligned to the effective command selected for the
    current runtime.
    
    # Docs
    
    The Codex hooks/config reference should document `command_windows` as
    the Windows-only override for command hooks.
  • feat(connectors): support managed app tool approval requirements (#21061)
    ## Why
    
    Managed requirements can already centrally disable apps, but they could
    not express the per-tool app approval rules that normal config already
    supports. That left admins without a way to enforce connector tool
    approvals through `/etc/codex/requirements.toml` or cloud requirements.
    
    ## What changed
    
    - Extend app requirements with per-tool `approval_mode` entries.
    - Merge managed app tool requirements across managed sources while
    preserving higher-precedence exact tool settings.
    - Apply managed tool approvals separately from user app config so
    managed policy is matched only on raw MCP `tool.name`, while user config
    keeps the existing raw-name-then-title convenience fallback.
    - Add coverage for local requirements, cloud requirements parsing,
    managed-over-user precedence, and a title-collision case that must not
    widen managed auto-approval.
    
    ## Configuration shape
    
    Local `/etc/codex/requirements.toml` and cloud requirements use the same
    TOML shape:
    
    ```toml
    [apps.connector_123123.tools."calendar/list_events"]
    approval_mode = "approve"
    ```
    
    This is a per-tool approval rule keyed by app ID and raw MCP tool name,
    not an app-level boolean such as `apps.connector_123123.approve = true`.
  • 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.

  • Fix goal update and add /goal edit command in TUI (#21954)
    ## Why
    
    Users have requested the ability to edit a goal's objective after a goal
    has been created. This PR exposes a new `/goal edit` command in the TUI
    to address this request.
    
    In the process of implementing this, I also noticed an existing bug in
    the goal runtime. When a goal's objective is updated through the
    `thread/goal/set` app server API, the goal runtime didn't emit a new
    steering prompt to tell the agent about the new objective. This PR also
    fixes this hole.
    
    ## What Changed
    
    - Adds `/goal edit` in the TUI, opening an edit box prefilled with the
    current goal objective.
    - Keeps active and paused goals in their current state, resets completed
    goals to active, keeps budget-limited goals budget-limited, and
    preserves the existing token budget.
    - Changes the existing `thread/goal/set` behavior so editing an
    objective preserves goal accounting instead of resetting it. The older
    reset-on-new-objective behavior was left over from before
    `thread/goal/clear`; clients that need to reset accounting can now clear
    the existing goal and create a new one.
    - Reuses the existing goal set API path; this does not add or change
    app-server protocol surface area.
    - Adds a dedicated goal runtime steering prompt when an externally
    persisted goal mutation changes the objective, so active turns receive
    the updated objective.
    
    ## Validation
    
    - Make sure `/goal edit` returns an error if no goal currently exists
    - Make sure `/goal edit` displays an edit box that can be optionally
    canceled with no side effects
    - Make sure that an edited goal results in a steer so the agent starts
    pursuing the new objective
    - Make sure the new objective is reflected in the goal if you use
    `/goal` to display the goal summary
    - Make sure that `/goal edit` doesn't reset the token budget, time/token
    accounting on the updated goal
  • Fix side conversation config inheritance (#22106)
    Addresses #22101
    
    ## Why
    
    Side conversations are ephemeral forks of the active thread, but `/side`
    was building its fork config from the app-level config after refreshing
    it from disk. If the parent thread had runtime settings that differed
    from the current persisted defaults, such as a changed model, reasoning
    effort, permissions, reviewer, or fast-mode selection, the side
    conversation could start with different behavior than its parent.
    
    ## What changed
    
    - Build side fork config from the active parent `ChatWidget` config,
    then overlay the parent thread's effective model, reasoning effort,
    service tier, and fast-mode opt-out state.
    - Forward model reasoning summary, verbosity, personality, web search
    mode, and service-tier overrides through TUI app-server
    start/resume/fork lifecycle params.
    - Add focused tests for parent runtime inheritance, side developer
    guardrail preservation, and lifecycle param forwarding.
  • Persist /goal commands in history (#21860)
    ## Summary
    
    A user reported that `/goal` was not saved to the TUI command history,
    which made it unavailable for later recall even though other accepted
    input paths persist history entries.
    
    This updates the TUI goal slash-command dispatch so successful `/goal`
    invocations append the command text to message history. The change
    covers the bare `/goal` menu command, goal control commands such as
    `/goal pause`, and objective-setting commands such as `/goal improve
    benchmark coverage`.
    
    ## Verification
    
    - `cargo test -p codex-tui goal_slash_command -- --nocapture`
  • 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`

  • fix(tui): preserve Shift+Enter in tmux csi-u panes (#21943)
    ## Why
    
    Inside tmux, `Shift+Enter` can still reach Codex as a plain `Enter` even
    when tmux has extended keys enabled. In `csi-u` tmux panes, Codex needs
    to request `modifyOtherKeys` mode 2 so tmux moves the pane from `VT10x`
    into extended-key mode and preserves the Shift modifier. Without that
    extra request, composer `Shift+Enter` submits the draft instead of
    inserting a newline.
    
    Fixes #21699.
    
    ## What Changed
    
    - Detect tmux sessions and read the active `extended-keys-format`,
    preferring the pane-local value before falling back to the global
    option.
    - Request `modifyOtherKeys` mode 2 for tmux panes using `csi-u` extended
    keys, and reset it when restoring keyboard reporting.
    - Add unit coverage for tmux detection, the format gate, and the emitted
    `modifyOtherKeys` escape sequence.
    
    ## How to Test
    
    1. In tmux, configure:
       ```tmux
       set-option -g extended-keys on
       set-option -g extended-keys-format csi-u
       ```
    2. Start Codex in a fresh tmux pane from this branch.
    3. From another pane, confirm the Codex pane reports `mode=Ext 2`:
       ```bash
    tmux list-panes -a -F '#{session_name}:#{window_index}.#{pane_index}
    mode=#{pane_key_mode} cmd=#{pane_current_command}'
       ```
    4. Type a draft in the composer and press `Shift+Enter`; confirm it
    inserts a newline instead of submitting.
    5. Also confirm plain `Enter` still submits as before.
    
    Targeted tests:
    - `cargo test -p codex-tui`
    
    ## Notes
    
    - Manual verification used both real `Shift+Enter` in iTerm2/tmux and
    `tmux send-keys ... S-Enter` to confirm the tmux pane changes from
    `VT10x` to `Ext 2` and preserves newline behavior.
    - On this checkout, the broader `codex-tui` test run currently reaches
    unrelated existing failures in `status::tests::*` plus a later stack
    overflow in
    `tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.
  • 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.
  • Avoid blocking TUI on agent metadata hydration (#21870)
    ## Why
    
    Fixes #16688.
    
    The TUI currently hydrates collab receiver metadata by awaiting
    `thread/read` before each active-thread notification is rendered. During
    large subagent fan-outs, the embedded app-server can be busy starting
    agents and processing spawn work, so those synchronous metadata reads
    queue behind the fan-out and block the TUI event loop. That makes the UI
    appear frozen even though the underlying agent work can continue.
    
    ## What Changed
    
    - Replaced eager `thread/read` metadata hydration on the active
    notification path with local receiver-thread caching.
    - Kept `ThreadStarted` and picker refreshes as the places that fill in
    agent nickname/role metadata when it is available.
    - Skipped caching receiver threads that are explicitly reported as
    `NotFound`, avoiding live-looking ghost entries for failed stale-agent
    calls.
    - Added TUI tests covering both local receiver caching and `NotFound`
    suppression.
    
    ## Verification
    
    - `cargo test -p codex-tui collab_receiver_notification`
    - `just fix -p codex-tui`
    
    I also ran the full `cargo test -p codex-tui`; the new test passed, but
    the full process later aborted with an unrelated stack overflow in
    `tests::fork_last_filters_latest_session_by_cwd_unless_show_all`.
