  • feat: include available decisions in command approval requests (#12758)
    Command-approval clients currently infer which choices to show from
    side-channel fields like `networkApprovalContext`,
    `proposedExecpolicyAmendment`, and `additionalPermissions`. That makes
    the request shape harder to evolve, and it forces each client to
    replicate the server's heuristics instead of receiving the exact
    decision list for the prompt.
    
    This PR introduces a mapping between `CommandExecutionApprovalDecision`
    and `codex_protocol::protocol::ReviewDecision`:
    
    ```rust
    impl From<CoreReviewDecision> for CommandExecutionApprovalDecision {
        fn from(value: CoreReviewDecision) -> Self {
            match value {
                CoreReviewDecision::Approved => Self::Accept,
                CoreReviewDecision::ApprovedExecpolicyAmendment {
                    proposed_execpolicy_amendment,
                } => Self::AcceptWithExecpolicyAmendment {
                    execpolicy_amendment: proposed_execpolicy_amendment.into(),
                },
                CoreReviewDecision::ApprovedForSession => Self::AcceptForSession,
                CoreReviewDecision::NetworkPolicyAmendment {
                    network_policy_amendment,
                } => Self::ApplyNetworkPolicyAmendment {
                    network_policy_amendment: network_policy_amendment.into(),
                },
                CoreReviewDecision::Abort => Self::Cancel,
                CoreReviewDecision::Denied => Self::Decline,
            }
        }
    }
    ```
    
    And updates `CommandExecutionRequestApprovalParams` to have a new field:
    
    ```rust
    available_decisions: Option<Vec<CommandExecutionApprovalDecision>>
    ```
    
    when, if specified, should make it easier for clients to display an
    appropriate list of options in the UI.
    
    This makes it possible for `CoreShellActionProvider::prompt()` in
    `unix_escalation.rs` to specify the `Vec<ReviewDecision>` directly,
    adding support for `ApprovedForSession` when approving a skill script,
    which was previously missing in the TUI.
    
    Note this results in a significant change to `exec_options()` in
    `approval_overlay.rs`, as the displayed options are now derived from
    `available_decisions: &[ReviewDecision]`.
    
    ## What Changed
    
    - Add `available_decisions` to
    [`ExecApprovalRequestEvent`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/protocol/src/approvals.rs#L111-L175),
    including helpers to derive the legacy default choices when older
    senders omit the field.
    - Map `codex_protocol::protocol::ReviewDecision` to app-server
    `CommandExecutionApprovalDecision` and expose the ordered list as
    experimental `availableDecisions` in
    [`CommandExecutionRequestApprovalParams`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/app-server-protocol/src/protocol/v2.rs#L3798-L3807).
    - Thread optional `available_decisions` through the core approval path
    so Unix shell escalation can explicitly request `ApprovedForSession` for
    session-scoped approvals instead of relying on client heuristics.
    [`unix_escalation.rs`](https://github.com/openai/codex/blob/de00e932dd9801de0a4faac0519162099753f331/codex-rs/core/src/tools/runtimes/shell/unix_escalation.rs#L194-L214)
    - Update the TUI approval overlay to build its buttons from the ordered
    decision list, while preserving the legacy fallback when
    `available_decisions` is missing.
    - Update the app-server README, test client output, and generated schema
    artifacts to document and surface the new field.
    
    ## Testing
    
    - Add `approval_overlay.rs` coverage for explicit decision lists,
    including the generic `ApprovedForSession` path and network approval
    options.
    - Update `chatwidget/tests.rs` and app-server protocol tests to populate
    the new optional field and keep older event shapes working.
    
    ## Developers Docs
    
    - If we document `item/commandExecution/requestApproval` on
    [developers.openai.com/codex](https://developers.openai.com/codex), add
    experimental `availableDecisions` as the preferred source of approval
    choices and note that older servers may omit it.

  • make 5.3-codex visible in cli for api users (#12808)
    5.3-codex released in api, mark it visible for API users via bundled
    `models.json`.
  • Promote js_repl to experimental with Node requirement (#12712)
    ## Summary
    
    - Promote `js_repl` to an experimental feature that users can enable
    from `/experimental`.
    - Add `js_repl` experimental metadata, including the Node prerequisite
    and activation guidance.
    - Add regression coverage for the feature metadata and the
    `/experimental` popup.
    
    ## What Changed
    
    - Changed `Feature::JsRepl` from `Stage::UnderDevelopment` to
    `Stage::Experimental`.
    - Added experimental metadata for `js_repl` in `core/src/features.rs`:
      - name: `JavaScript REPL`
    - description: calls out interactive website debugging, inline
    JavaScript execution, and the required Node version (`>= v24.13.1`)
    - announcement: tells users to enable it, then start a new chat or
    restart Codex
    - Added a core unit test that verifies:
      - `js_repl` is experimental
      - `js_repl` is disabled by default
    - the hardcoded Node version in the description matches
    `node-version.txt`
    - Added a TUI test that opens the `/experimental` popup and verifies the
    rendered `js_repl` entry includes the Node requirement text.
    
    ## Testing
    
    - `just fmt`
    - `cargo test -p codex-tui`
    - `cargo test -p codex-core` (unit-test phase passed; stopped during the
    long `tests/all.rs` integration suite)
  • Surface skill permission profiles in zsh-fork exec approvals (#12753)
    ## Summary
    
    - Preserve each skill’s raw permissions block as a permission_profile on
    SkillMetadata during skill loading.
    - Keep compiling that same metadata into the existing runtime
    Permissions object, so current enforcement
        behavior stays intact.
    - When zsh-fork intercepts execution of a script that belongs to a
    skill, include the skill’s
        permission_profile in the exec approval request.
    - This lets approval UIs show the extra filesystem access the skill
    declared when prompting for approval.
  • fix: chatwidget was not honoring approval_id for an ExecApprovalRequestEvent (#12746)
    ## Why
    
    `ExecApprovalRequestEvent` can carry a distinct `approval_id` for
    subcommand approvals, including the `execve`-intercepted zsh-fork path.
    
    The session registers the pending approval callback under `approval_id`
    when one is present, but `ChatWidget` was stashing `call_id` in the
    approval modal state. When the user approved the command in the TUI, the
    response was sent back with the wrong identifier, so the pending
    approval could not be matched and the approval callback would not
    resolve.
    
    Note `approval_id` was introduced in
    https://github.com/openai/codex/pull/12051.
    
    ## What changed
    
    - In `tui/src/chatwidget.rs`, `ChatWidget` now uses
    `ExecApprovalRequestEvent::effective_approval_id()` when constructing
    `ApprovalRequest::Exec`.
    - That preserves the existing behavior for normal shell and
    `unified_exec` approvals, where `approval_id` is absent and the
    effective id still falls back to `call_id`.
    - For subcommand approvals that provide a distinct `approval_id`, the
    TUI now sends back the same key that
    `Session::request_command_approval()` registered.
    
    ## Verification
    
    - Traced the approval flow end to end to confirm the same effective
    approval id is now used on both sides of the round trip:
    - `Session::request_command_approval()` registers the pending callback
    under `approval_id.unwrap_or(call_id)`.
    - `ChatWidget` now emits `Op::ExecApproval` with that same effective id.
  • fix: clarify the value of SkillMetadata.path (#12729)
    Rename `SkillMetadata.path` to `SkillMetadata.path_to_skills_md` for
    clarity.
    
    Would ideally change the type to `AbsolutePathBuf`, but that can be done
    later.

  • Add TUI realtime conversation mode (#12687)
    - Add a hidden `realtime_conversation` feature flag and `/realtime`
    slash command for start/stop live voice sessions.
    - Reuse transcription composer/footer UI for live metering, stream mic
    audio, play assistant audio, render realtime user text events, and
    force-close on feature disable.

  • feat(core) Introduce Feature::RequestPermissions (#11871)
    ## Summary
    Introduces the initial implementation of Feature::RequestPermissions.
    RequestPermissions allows the model to request that a command be run
    inside the sandbox, with additional permissions, like writing to a
    specific folder. Eventually this will include other rules as well, and
    the ability to persist these permissions, but this PR is already quite
    large - let's get the core flow working and go from there!

  • feat(core): persist network approvals in execpolicy (#12357)
    ## Summary
    Persist network approval allow/deny decisions as `network_rule(...)`
    entries in execpolicy (not proxy config)
    
    It adds `network_rule` parsing + append support in `codex-execpolicy`,
    including `decision="prompt"` (parse-only; not compiled into proxy
    allow/deny lists)
    - compile execpolicy network rules into proxy allow/deny lists and
    update the live proxy state on approval
    - preserve requirements execpolicy `network_rule(...)` entries when
    merging with file-based execpolicy
    - reject broad wildcard hosts (for example `*`) for persisted
    `network_rule(...)`

  • fix(tui): queue steer Enter while final answer is still streaming to prevent dead state (#12569)
    ## Summary
    This fixes a TUI race (https://github.com/openai/codex/issues/11008)
    where pressing Enter with Steer enabled while the assistant is still
    streaming the final answer could put Codex into a non-recoverable
    “running” state (no further prompts handled until exiting and resuming).
    
    ## Root Cause
    In steer mode, `InputResult::Submitted` could submit immediately even
    while a final-answer stream was active. That immediate submission races
    with turn completion and can strand turn state.
    
    ## Fix
    When handling `InputResult::Submitted`, we now queue instead of
    immediate-submit if a final-answer stream is active
    (`stream_controller.is_some()`).
    
    This keeps behavior deterministic:
    - Prompt is preserved in the queue.
    - `on_task_complete()` drains queued input through
    `maybe_send_next_queued_input()`.
    - Follow-up prompts continue in FIFO order after completion.
    
    ## Why this resolves the “dead mode”
    The problematic timing window is now converted into queueing, so prompts
    entered during final streaming are not lost and are processed after the
    current output ends. The model continues handling prompts normally
    without requiring `/quit` + `resume`.
    
    ## Tests
    Added regression coverage in `tui/src/chatwidget/tests.rs`:
    
    - `steer_enter_queues_while_final_answer_stream_is_active`
    - `steer_enter_during_final_stream_preserves_follow_up_prompts_in_order`
    
    Both fail on old behavior and pass with this fix.

  • Handle orphan exec ends without clobbering active exploring cell (#12313)
    Summary
    - distinguish exec end handling targets (active tracking, active orphan

    exploring cells
    - ensure orphan ends flush existing exploring history when complete,
    insert standalone history entries, and keep active cells correct
    - add regression tests plus a snapshot covering the new behavior and
    expose the ExecCell completion result for verification

  • feat(tui): syntax highlighting via syntect with theme picker (#11447)
    ## Summary
    
    Adds syntax highlighting to the TUI for fenced code blocks in markdown
    responses and file diffs, plus a `/theme` command with live preview and
    persistent theme selection. Uses syntect (~250 grammars, 32 bundled
    themes, ~1 MB binary cost) — the same engine behind `bat`, `delta`, and
    `xi-editor`. Includes guardrails for large inputs, graceful fallback to
    plain text, and SSH-aware clipboard integration for the `/copy` command.

    />
    
    ## Problem
    
    Code blocks in the TUI (markdown responses and file diffs) render
    without syntax highlighting, making it hard to scan code at a glance.
    Users also have no way to pick a color theme that matches their terminal
    aesthetic.
    
    ## Mental model
    
    The highlighting system has three layers:
    
    1. **Syntax engine** (`render::highlight`) -- a thin wrapper around
    syntect + two-face. It owns a process-global `SyntaxSet` (~250 grammars)
    and a `RwLock<Theme>` that can be swapped at runtime. All public entry
    points accept `(code, lang)` and return ratatui `Span`/`Line` vectors or
    `None` when the language is unrecognized or the input exceeds safety
    guardrails.
    
    2. **Rendering consumers** -- `markdown_render` feeds fenced code blocks
    through the engine; `diff_render` highlights Add/Delete content as a
    whole file and Update hunks per-hunk (preserving parser state across
    hunk lines). Both callers fall back to plain unstyled text when the
    engine returns `None`.
    
    3. **Theme lifecycle** -- at startup the config's `tui.theme` is
    resolved to a syntect `Theme` via `set_theme_override`. At runtime the
    `/theme` picker calls `set_syntax_theme` to swap themes live; on cancel
    it restores the snapshot taken at open. On confirm it persists `[tui]
    theme = "..."` to config.toml.
    
    ## Non-goals
    
    - Inline diff highlighting (word-level change detection within a line).
    - Semantic / LSP-backed highlighting.
    - Theme authoring tooling; users supply standard `.tmTheme` files.
    
    ## Tradeoffs
    
    | Decision | Upside | Downside |
    | ------------------------------------------------ |
    ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    |
    -----------------------------------------------------------------------------------------------------------------------
    |
    | syntect over tree-sitter / arborium | ~1 MB binary increase for ~250
    grammars + 32 themes; battle-tested crate powering widely-used tools
    (`bat`, `delta`, `xi-editor`). tree-sitter would add ~12 MB for 20-30
    languages or ~35 MB for full coverage. | Regex-based; less structurally
    accurate than tree-sitter for some languages (e.g. language injections
    like JS-in-HTML). |
    | Global `RwLock<Theme>` | Enables live `/theme` preview without
    threading Theme through every call site | Lock contention risk
    (mitigated: reads vastly outnumber writes, single UI thread) |
    | Skip background / italic / underline from themes | Terminal BG
    preserved, avoids ugly rendering on some themes | Themes that rely on
    these properties lose fidelity |
    | Guardrails: 512 KB / 10k lines | Prevents pathological stalls on huge
    diffs or pastes | Very large files render without color |
    
    ## Architecture
    
    ```
    config.toml  ─[tui.theme]─>  set_theme_override()  ─>  THEME (RwLock)
                                                                  │

                      ─── current_syntax_theme()      // snapshot for cancel
                      ─── resolve_theme_by_name(name) // lookup by kebab-case
    ```
    
    Key files:
    
    - `tui/src/render/highlight.rs` -- engine, theme management, guardrails
    - `tui/src/diff_render.rs` -- syntax-aware diff line wrapping
    - `tui/src/theme_picker.rs` -- `/theme` command builder
    - `tui/src/bottom_pane/list_selection_view.rs` -- side content panel,
    callbacks
    - `core/src/config/types.rs` -- `Tui::theme` field
    - `core/src/config/edit.rs` -- `syntax_theme_edit()` helper
    
    ## Observability
    
    - `tracing::warn` when a configured theme name cannot be resolved.
    - `Config::startup_warnings` surfaces the same message as a TUI banner.
    - `tracing::error` when persisting theme selection fails.
    
    ## Tests
    
    - Unit tests in `highlight.rs`: language coverage, fallback behavior,
    CRLF stripping, style conversion, guardrail enforcement, theme name
    mapping exhaustiveness.
    - Unit tests in `diff_render.rs`: snapshot gallery at multiple terminal
    sizes (80x24, 94x35, 120x40), syntax-highlighted wrapping, large-diff
    guardrail, rename-to-different-extension highlighting, parser state
    preservation across hunk lines.
    - Unit tests in `theme_picker.rs`: preview rendering (wide + narrow),
    dim overlay on deletions, subtitle truncation, cancel-restore, fallback
    for unavailable configured theme.
    - Unit tests in `list_selection_view.rs`: side layout geometry, stacked
    fallback, buffer clearing, cancel/selection-changed callbacks.
    - Integration test in `lib.rs`: theme warning uses the final
    (post-resume) config.
    
    ## Cargo Deny: Unmaintained Dependency Exceptions
    
    This PR adds two `cargo deny` advisory exceptions for transitive
    dependencies pulled in by `syntect v5.3.0`:
    
    | Advisory | Crate | Status |
    |----------|-------|--------|
    | RUSTSEC-2024-0320 | `yaml-rust` | Unmaintained (maintainer
    unreachable) |
    | RUSTSEC-2025-0141 | `bincode` | Unmaintained (development ceased;
    v1.3.3 considered complete) |
    
    **Why this is safe in our usage:**
    
    - Neither advisory describes a known security vulnerability. Both are
    "unmaintained" notices only.
    - `bincode` is used by syntect to deserialize pre-compiled syntax sets.
    Again, these are **static vendored artifacts** baked into the binary at
    build time. No user-supplied bincode data is ever deserialized. - Attack
    surface is zero for both crates; exploitation would require a
    supply-chain compromise of our own build artifacts.
    - These exceptions can be removed when syntect migrates to `yaml-rust2`
    and drops `bincode`, or when alternative crates are available upstream.
  • Prevent replayed runtime events from forcing active status (#12420)
    Fixes #11852
    
    Resume replay was applying transient runtime events (`TurnStarted`,
    `StreamError`) as if they were live, which could leave the TUI stuck in
    a stale `Working` / `Reconnecting...` state after resuming an
    interrupted reconnect.
    
    This change makes replay transcript-oriented for these events by:
    - skipping retry-status restoration for replayed non-stream events
    - ignoring replayed `TurnStarted` for task-running state
    - ignoring replayed `StreamError` for reconnect/status UI
    
    Also adds TUI regression tests and snapshot coverage for the interrupted
    reconnect replay case.
  • chore: remove codex-core public protocol/shell re-exports (#12432)
    ## Why
    
    `codex-rs/core/src/lib.rs` re-exported a broad set of types and modules
    from `codex-protocol` and `codex-shell-command`. That made it easy for
    workspace crates to import those APIs through `codex-core`, which in
    turn hides dependency edges and makes it harder to reduce compile-time
    coupling over time.
    
    This change removes those public re-exports so call sites must import
    from the source crates directly. Even when a crate still depends on
    `codex-core` today, this makes dependency boundaries explicit and
    unblocks future work to drop `codex-core` dependencies where possible.
    
    ## What Changed
    
    - Removed public re-exports from `codex-rs/core/src/lib.rs` for:
    - `codex_protocol::protocol` and related protocol/model types (including
    `InitialHistory`)
      - `codex_protocol::config_types` (`protocol_config_types`)
    - `codex_shell_command::{bash, is_dangerous_command, is_safe_command,
    parse_command, powershell}`
    - Migrated workspace Rust call sites to import directly from:
      - `codex_protocol::protocol`
      - `codex_protocol::config_types`
      - `codex_protocol::models`
      - `codex_shell_command`
    - Added explicit `Cargo.toml` dependencies (`codex-protocol` /
    `codex-shell-command`) in crates that now import those crates directly.
    - Kept `codex-core` internal modules compiling by using `pub(crate)`
    aliases in `core/src/lib.rs` (internal-only, not part of the public
    API).
    - Updated the two utility crates that can already drop a `codex-core`
    dependency edge entirely:
      - `codex-utils-approval-presets`
      - `codex-utils-cli`
    
    ## Verification
    
    - `cargo test -p codex-utils-approval-presets`
    - `cargo test -p codex-utils-cli`
    - `cargo check --workspace --all-targets`
    - `just clippy`
  • Improve Plan mode reasoning selection flow (#12303)
    Addresses https://github.com/openai/codex/issues/11013
    
    ## Summary
    - add a Plan implementation path in the TUI that lets users choose
    reasoning before switching to Default mode and implementing
    - add Plan-mode reasoning scope handling (Plan-only override vs
    all-modes default), including config/schema/docs plumbing for
    `plan_mode_reasoning_effort`
    - remove the hardcoded Plan preset medium default and make the reasoning
    popup reflect the active Plan override as `(current)`
    - split the collaboration-mode switch notification UI hint into #12307
    to keep this diff focused

  • fix(tui): queued-message edit shortcut unreachable in some terminals (#12240)
    ## Problem
    
    The TUI's "edit queued message" shortcut (Alt+Up) is either silently
    swallowed or recognized as another key combination by Apple Terminal,
    Warp, and VSCode's integrated terminal on macOS. Users in those
    environments see the hint but pressing the keys does nothing.
    
    ## Mental model
    
    When a model turn is in progress the user can still type follow-up
    messages. These are queued and displayed below the composer with a hint
    line showing how to pop the most recent one back into the editor. The
    hint text and the actual key handler must agree on which shortcut is
    used, and that shortcut must actually reach the TUI—i.e. it must not be
    intercepted by the host terminal.
    
    Three terminals are known to intercept Alt+Up: Apple Terminal (remaps it
    to cursor movement), Warp (consumes it for its own command palette), and
    VSCode (maps it to "move line up"). For these we use Shift+Left instead.

    ## Non-goals
    
    - Making the binding user-configurable at runtime (deferred to a broader
    keybinding-config effort).
    - Remapping any other shortcuts that might be terminal-specific.
    
    ## Tradeoffs
    
    - **Exhaustive match instead of a wildcard default.** The
    `queued_message_edit_binding_for_terminal` function explicitly lists
    every `TerminalName` variant. This is intentional: adding a new terminal
    to the enum will produce a compile error, forcing the author to decide
    which binding that terminal should use.
    
    - **Binding lives on `ChatWidget`, hint lives on `QueuedUserMessages`.**
    The key event handler that actually acts on the press is in
    `ChatWidget`, but the rendered hint text is inside `QueuedUserMessages`.
    These are kept in sync by `ChatWidget` calling
    `bottom_pane.set_queued_message_edit_binding(self.queued_message_edit_binding)`
    during construction. A mismatch would show the wrong hint but would not
    lose data.

    No new crates or public API surface. The only cross-crate dependency
    added is `codex_core::terminal::{TerminalName, terminal_info}`, which
    already existed for telemetry.
    
    ## Observability
    
    No new logging. Terminal detection already emits a `tracing::debug!` log
    line at startup with the detected terminal name, which is sufficient to
    diagnose binding mismatches.
    
    ## Tests
    
    - Existing `alt_up_edits_most_recent_queued_message` test is preserved
    and explicitly sets the Alt+Up binding to isolate from the host
    terminal.
    - New parameterized async tests verify Shift+Left works for Apple
    Terminal, Warp, and VSCode.
    - A sync unit test asserts the mapping table covers the three special
    terminals (Shift+Left) and that iTerm2 still gets Alt+Up.

  • [apps] Store apps tool cache in disk to reduce startup time. (#11822)
    We now write MCP tools from installed apps to disk cache so that they
    can be picked up instantly at startup. We still do a fresh fetch from
    remote MCP server but it's non blocking unless there's a cache miss.
    
    - [x] Store apps tool cache in disk to reduce startup time.
  • client side modelinfo overrides (#12101)
    TL;DR
    Add top-level `model_catalog_json` config support so users can supply a
    local model catalog override from a JSON file path (including adding new
    models) without backend changes.
    
    ### Problem
    Codex previously had no clean client-side way to replace/overlay model
    catalog data for local testing of model metadata and new model entries.
    
    ### Fix
    - Add top-level `model_catalog_json` config field (JSON file path).
    - Apply catalog entries when resolving `ModelInfo`:
      1. Base resolved model metadata (remote/fallback)
      2. Catalog overlay from `model_catalog_json`
    3. Existing global top-level overrides (`model_context_window`,
    `model_supports_reasoning_summaries`, etc.)
    
    ### Note
    Will revisit per-field overrides in a follow-up
    
    ### Tests
    Added tests
  • feat(core): plumb distinct approval ids for command approvals (#12051)
    zsh fork PR stack:
    - https://github.com/openai/codex/pull/12051 👈 
    - https://github.com/openai/codex/pull/12052
    
    With upcoming support for a fork of zsh that allows us to intercept
    `execve` and run execpolicy checks for each subcommand as part of a
    `CommandExecution`, it will be possible for there to be multiple
    approval requests for a shell command like `/path/to/zsh -lc 'git status
    && rg \"TODO\" src && make test'`.
    
    To support that, this PR introduces a new `approval_id` field across
    core, protocol, and app-server so that we can associate approvals
    properly for subcommands.
  • [apps] Expose more fields from apps listing endpoints. (#11706)
    - [x] Expose app_metadata, branding, and labels in AppInfo.

    We see issues like #11527 when a user has `remote_models` disabled, as
    we always use the default fallback `ModelInfo`. This causes issues with
    model performance.
    
    Builds on #11690, which helps by warning the user when they are using
    the default fallback. This PR will make that happen much less frequently
    as an accidental consequence of disabling `remote_models`.

  • feat(core): add structured network approval plumbing and policy decision model (#11672)
    ### Description
    #### Summary
    Introduces the core plumbing required for structured network approvals
    
    #### What changed
    - Added structured network policy decision modeling in core.
    - Added approval payload/context types needed for network approval
    semantics.
    - Wired shell/unified-exec runtime plumbing to consume structured
    decisions.
    - Updated related core error/event surfaces for structured handling.
    - Updated protocol plumbing used by core approval flow.
    - Included small CLI debug sandbox compatibility updates needed by this
    layer.
    
    #### Why
    establishes the minimal backend foundation for network approvals without
    yet changing high-level orchestration or TUI behavior.
    
    #### Notes
    - Behavior remains constrained by existing requirements/config gating.
    - Follow-up PRs in the stack handle orchestration, UX, and app-server
    integration.

  • feat(skills): add permission profiles from openai.yaml metadata (#11658)
    ## Summary
    
    This PR adds support for skill-level permissions in .codex/openai.yaml
    and wires that through the skill loading pipeline.
    
      ## What’s included
    
    1. Added a new permissions section for skills (network, filesystem, and
    macOS-related access).
    2. Implemented permission parsing/normalization and translation into
    runtime permission profiles.
    3. Threaded the new permission profile through SkillMetadata and loader
    flow.
    
      ## Follow-up
    
    A follow-up PR will connect these permission profiles to actual sandbox
    enforcement and add user approval prompts for executing binaries/scripts
    from skill directories.
    
    
     ## Example 
    `openai.yaml` snippet:
    ```
      permissions:
        network: true
        fs_read:
          - "./data"
          - "./data"

  • tui: preserve remote image attachments across resume/backtrack (#10590)
    ## Summary
    This PR makes app-server-provided image URLs first-class attachments in
    TUI, so they survive resume/backtrack/history recall and are resubmitted
    correctly.
    
    <img width="715" height="491" alt="Screenshot 2026-02-12 at 8 27 08 PM"
    src="https://github.com/user-attachments/assets/226cbd35-8f0c-4e51-a13e-459ef5dd1927"
    />
    
    Can delete the attached image upon backtracking:
    <img width="716" height="301" alt="Screenshot 2026-02-12 at 8 27 31 PM"
    src="https://github.com/user-attachments/assets/4558d230-f1bd-4eed-a093-8e1ab9c6db27"
    />
    
    In both history and composer, remote images are rendered as normal
    `[Image #N]` placeholders, with numbering unified with local images.
    
    ## What changed
    - Plumb remote image URLs through TUI message state:
      - `UserHistoryCell`
      - `BacktrackSelection`
      - `ChatComposerHistory::HistoryEntry`
      - `ChatWidget::UserMessage`
    - Show remote images as placeholder rows inside the composer box (above
    textarea), and in history cells.
    - Support keyboard selection/deletion for remote image rows in composer
    (`Up`/`Down`, `Delete`/`Backspace`).
    - Preserve remote-image-only turns in local composer history (Up/Down
    recall), including restore after backtrack.
    - Ensure submit/queue/backtrack resubmit include remote images in model
    input (`UserInput::Image`), and keep request shape stable for
    remote-image-only turns.
    - Keep image numbering contiguous across remote + local images:
      - remote images occupy `[Image #1]..[Image #M]`
      - local images start at `[Image #M+1]`
      - deletion renumbers consistently.
    - In protocol conversion, increment shared image index for remote images
    too, so mixed remote/local image tags stay in a single sequence.
    - Simplify restore logic to trust in-memory attachment order (no
    placeholder-number parsing path).
    - Backtrack/replay rollback handling now queues trims through
    `AppEvent::ApplyThreadRollback` and syncs transcript overlay/deferred
    lines after trims, so overlay/transcript state stays consistent.
    - Trim trailing blank rendered lines from user history rendering to
    avoid oversized blank padding.
    
    ## Docs + tests
    - Updated: `docs/tui-chat-composer.md` (remote image flow,
    selection/deletion, numbering offsets)
    - Added/updated tests across `tui/src/chatwidget/tests.rs`,
    `tui/src/app.rs`, `tui/src/app_backtrack.rs`, `tui/src/history_cell.rs`,
    and `tui/src/bottom_pane/chat_composer.rs`
    - Added snapshot coverage for remote image composer states, including
    deleting the first of two remote images.
    
    ## Validation
    - `just fmt`
    - `cargo test -p codex-tui`

  • feat(tui): prevent macOS idle sleep while turns run (#11711)
    ## Summary
    - add a shared `codex-core` sleep inhibitor that uses native macOS IOKit
    assertions (`IOPMAssertionCreateWithName` / `IOPMAssertionRelease`)
    instead of spawning `caffeinate`
    - wire sleep inhibition to turn lifecycle in `tui` (`TurnStarted`
    enables; `TurnComplete` and abort/error finalization disable)
    - gate this behavior behind a `/experimental` feature toggle
    (`[features].prevent_idle_sleep`) instead of a dedicated `[tui]` config
    flag
    - expose the toggle in `/experimental` on macOS; keep it under
    development on other platforms
    - keep behavior no-op on non-macOS targets

    - This PR targets `caffeinate -i` semantics: prevent *idle system sleep*
    while allowing display idle sleep.
    - `caffeinate -i` mapping in Apple open source (`assertionMap`):
      - `kIdleAssertionFlag -> kIOPMAssertionTypePreventUserIdleSystemSleep`
    - Source:
    https://github.com/apple-oss-distributions/PowerManagement/blob/PowerManagement-1846.60.12/caffeinate/caffeinate.c#L52-L54

      - https://developer.apple.com/library/archive/qa/qa1340/_index.html
    
    ## Codex Electron vs this PR (full stack path)
    - Codex Electron app requests sleep blocking with
    `powerSaveBlocker.start("prevent-app-suspension")`:
    -
    https://github.com/openai/codex/blob/main/codex/codex-vscode/electron/src/electron-message-handler.ts
    - Electron maps that string to Chromium wake lock type
    `kPreventAppSuspension`:
    -
    https://github.com/electron/electron/blob/main/shell/browser/api/electron_api_power_save_blocker.cc
    - Chromium macOS backend maps wake lock types to IOKit assertion
    constants and calls IOKit:
      - `kPreventAppSuspension -> kIOPMAssertionTypeNoIdleSleep`
    - `kPreventDisplaySleep / kPreventDisplaySleepAllowDimming ->
    kIOPMAssertionTypeNoDisplaySleep`
    -
    https://github.com/chromium/chromium/blob/main/services/device/wake_lock/power_save_blocker/power_save_blocker_mac.cc
    
    ## Why this PR uses a different macOS constant name
    - This PR uses `"PreventUserIdleSystemSleep"` directly, via
    `IOPMAssertionCreateWithName`, in
    `codex-rs/core/src/sleep_inhibitor.rs`.
    - Apple’s IOKit header documents `kIOPMAssertionTypeNoIdleSleep` as
    deprecated and recommends `kIOPMAssertPreventUserIdleSystemSleep` /
    `kIOPMAssertionTypePreventUserIdleSystemSleep`:
    -
    https://github.com/apple-oss-distributions/IOKitUser/blob/IOKitUser-100222.60.2/pwr_mgt.subproj/IOPMLib.h#L1000-L1030
    - So Chromium and this PR are using different constant names, but
    semantically equivalent idle-system-sleep prevention behavior.
    
    ## Future platform support
    The architecture is intentionally set up for multi-platform extensions:
    - UI code (`tui`) only calls `SleepInhibitor::set_turn_running(...)` on
    turn lifecycle boundaries.
    - Platform-specific behavior is isolated in
    `codex-rs/core/src/sleep_inhibitor.rs` behind `cfg(...)` blocks.
    - Feature exposure is centralized in `core/src/features.rs` and surfaced
    via `/experimental`.
    - Adding new OS backends should not require additional TUI wiring; only
    the backend internals and feature stage metadata need to change.
    
    Potential follow-up implementations:
    - Windows:
    - Add a backend using Win32 power APIs
    (`SetThreadExecutionState(ES_CONTINUOUS | ES_SYSTEM_REQUIRED)` as
    baseline).
    - Optionally move to `PowerCreateRequest` / `PowerSetRequest` /
    `PowerClearRequest` for richer assertion semantics.
    - Linux:
    - Add a backend using logind inhibitors over D-Bus
    (`org.freedesktop.login1.Manager.Inhibit` with `what="sleep"`).
      - Keep a no-op fallback where logind/D-Bus is unavailable.
    
    This PR keeps the cross-platform API surface minimal so future PRs can
    add Windows/Linux support incrementally with low churn.

  • feat: introduce Permissions (#11633)
    ## Why
    We currently carry multiple permission-related concepts directly on
    `Config` for shell/unified-exec behavior (`approval_policy`,
    `sandbox_policy`, `network`, `shell_environment_policy`,
    `windows_sandbox_mode`).
    
    Consolidating these into one in-memory struct makes permission handling
    easier to reason about and sets up the next step: supporting named
    permission profiles (`[permissions.PROFILE_NAME]`) without changing
    behavior now.
    
    This change is mostly mechanical: it updates existing callsites to go
    through `config.permissions`, but it does not yet refactor those
    callsites to take a single `Permissions` value in places where multiple
    permission fields are still threaded separately.
    
    This PR intentionally **does not** change the on-disk `config.toml`
    format yet and keeps compatibility with legacy config keys.
    
    ## What Changed
    - Introduced `Permissions` in `core/src/config/mod.rs`.
    - Added `Config::permissions` and moved effective runtime permission
    fields under it:
      - `approval_policy`
      - `sandbox_policy`
      - `network`
      - `shell_environment_policy`
      - `windows_sandbox_mode`
    - Updated config loading/building so these effective values are still
    derived from the same existing config inputs and constraints.
    - Updated Windows sandbox helpers/resolution to read/write via
    `permissions`.
    - Threaded the new field through all permission consumers across core
    runtime, app-server, CLI/exec, TUI, and sandbox summary code.
    - Updated affected tests to reference `config.permissions.*`.
    - Renamed the struct/field from
    `EffectivePermissions`/`effective_permissions` to
    `Permissions`/`permissions` and aligned variable naming accordingly.
    
    ## Verification
    - `just fix -p codex-core -p codex-tui -p codex-cli -p codex-app-server
    -p codex-exec -p codex-utils-sandbox-summary`
    - `cargo build -p codex-core -p codex-tui -p codex-cli -p
    codex-app-server -p codex-exec -p codex-utils-sandbox-summary`
  • feat(app-server): experimental flag to persist extended history (#11227)
    This PR adds an experimental `persist_extended_history` bool flag to
    app-server thread APIs so rollout logs can retain a richer set of
    EventMsgs for non-lossy Thread > Turn > ThreadItems reconstruction (i.e.
    on `thread/resume`).
    
    ### Motivation
    Today, our rollout recorder only persists a small subset (e.g. user
    message, reasoning, assistant message) of `EventMsg` types, dropping a
    good number (like command exec, file change, etc.) that are important
    for reconstructing full item history for `thread/resume`, `thread/read`,
    and `thread/fork`.
    
    Some clients want to be able to resume a thread without lossiness. This
    lossiness is primarily a UI thing, since what the model sees are
    `ResponseItem` and not `EventMsg`.
    
    ### Approach
    This change introduces an opt-in `persist_full_history` flag to preserve
    those events when you start/resume/fork a thread (defaults to `false`).
    
    This is done by adding an `EventPersistenceMode` to the rollout
    recorder:
    - `Limited` (existing behavior, default)
    - `Extended` (new opt-in behavior)
    
    In `Extended` mode, persist additional `EventMsg` variants needed for
    non-lossy app-server `ThreadItem` reconstruction. We now store the
    following ThreadItems that we didn't before:
    - web search
    - command execution
    - patch/file changes
    - MCP tool calls
    - image view calls
    - collab tool outcomes
    - context compaction
    - review mode enter/exit
    
    For **command executions** in particular, we truncate the output using
    the existing `truncate_text` from core to store an upper bound of 10,000
    bytes, which is also the default value for truncating tool outputs shown
    to the model. This keeps the size of the rollout file and command
    execution items returned over the wire reasonable.
    
    And we also persist `EventMsg::Error` which we can now map back to the
    Turn's status and populates the Turn's error metadata.
    
    #### Updates to EventMsgs
    To truly make `thread/resume` non-lossy, we also needed to persist the
    `status` on `EventMsg::CommandExecutionEndEvent` and
    `EventMsg::PatchApplyEndEvent`. Previously it was not obvious whether a
    command failed or was declined (similar for apply_patch). These
    EventMsgs were never persisted before so I made it a required field.

  • feat: make sandbox read access configurable with ReadOnlyAccess (#11387)
    `SandboxPolicy::ReadOnly` previously implied broad read access and could
    not express a narrower read surface.
    This change introduces an explicit read-access model so we can support
    user-configurable read restrictions in follow-up work, while preserving
    current behavior today.
    
    It also ensures unsupported backends fail closed for restricted-read
    policies instead of silently granting broader access than intended.
    
    ## What
    
    - Added `ReadOnlyAccess` in protocol with:
      - `Restricted { include_platform_defaults, readable_roots }`
      - `FullAccess`
    - Updated `SandboxPolicy` to carry read-access configuration:
      - `ReadOnly { access: ReadOnlyAccess }`
      - `WorkspaceWrite { ..., read_only_access: ReadOnlyAccess }`
    - Preserved existing behavior by defaulting current construction paths
    to `ReadOnlyAccess::FullAccess`.
    - Threaded the new fields through sandbox policy consumers and call
    sites across `core`, `tui`, `linux-sandbox`, `windows-sandbox`, and
    related tests.
    - Updated Seatbelt policy generation to honor restricted read roots by
    emitting scoped read rules when full read access is not granted.
    - Added fail-closed behavior on Linux and Windows backends when
    restricted read access is requested but not yet implemented there
    (`UnsupportedOperation`).
    - Regenerated app-server protocol schema and TypeScript artifacts,
    including `ReadOnlyAccess`.
    
    ## Compatibility / rollout
    
    - Runtime behavior remains unchanged by default (`FullAccess`).
    - API/schema changes are in place so future config wiring can enable
    restricted read access without another policy-shape migration.

  • feat: split codex-common into smaller utils crates (#11422)
    We are removing feature-gated shared crates from the `codex-rs`
    workspace. `codex-common` grouped several unrelated utilities behind
    `[features]`, which made dependency boundaries harder to reason about
    and worked against the ongoing effort to eliminate feature flags from
    workspace crates.
    
    Splitting these utilities into dedicated crates under `utils/` aligns
    this area with existing workspace structure and keeps each dependency
    explicit at the crate boundary.
    
    ## What changed
    
    - Removed `codex-rs/common` (`codex-common`) from workspace members and
    workspace dependencies.
    - Added six new utility crates under `codex-rs/utils/`:
      - `codex-utils-cli`
      - `codex-utils-elapsed`
      - `codex-utils-sandbox-summary`
      - `codex-utils-approval-presets`
      - `codex-utils-oss`
      - `codex-utils-fuzzy-match`
    - Migrated the corresponding modules out of `codex-common` into these
    crates (with tests), and added matching `BUILD.bazel` targets.
    - Updated direct consumers to use the new crates instead of
    `codex-common`:
      - `codex-rs/cli`
      - `codex-rs/tui`
      - `codex-rs/exec`
      - `codex-rs/app-server`
      - `codex-rs/mcp-server`
      - `codex-rs/chatgpt`
      - `codex-rs/cloud-tasks`
    - Updated workspace lockfile entries to reflect the new dependency graph
    and removal of `codex-common`.
