• feat(linux-sandbox): add bwrap support (#9938)

  ## Summary
  This PR introduces a gated Bubblewrap (bwrap) Linux sandbox path. The
  curent Linux sandbox path relies on in-process restrictions (including
  Landlock). Bubblewrap gives us a more uniform filesystem isolation
  model, especially explicit writable roots with the option to make some
  directories read-only and granular network controls.
  
  This is behind a feature flag so we can validate behavior safely before
  making it the default.
  
  - Added temporary rollout flag:
    - `features.use_linux_sandbox_bwrap`
  - Preserved existing default path when the flag is off.
  - In Bubblewrap mode:
  - Added internal retry without /proc when /proc mount is not permitted
  by the host/container.

• Add a codex.rate_limits event for websockets (#10324)

  When communicating over websockets, we can't rely on headers to deliver
  rate limit information. This PR adds a `codex.rate_limits` event that
  the server can pass to the client to inform them about rate limit usage.
  The client parses this data the same way we parse rate limit headers in
  HTTP mode.
  
  This PR also wires up the etag and reasoning headers for websockets

• chore(arg0): advisory-lock janitor for codex tmp paths (#10039)

  ## Description
  
  ### What changed
  - Switch the arg0 helper root from `~/.codex/tmp/path` to
  `~/.codex/tmp/path2`
  - Add `Arg0PathEntryGuard` to keep both the `TempDir` and an exclusive
  `.lock` file alive for the process lifetime
  - Add a startup janitor that scans `path2` and deletes only directories
  whose lock can be acquired
  
  ### Tests
  - `cargo clippy -p codex-arg0`
  - `cargo clippy -p codex-core`
  - `cargo test -p codex-arg0`
  - `cargo test -p codex-core`

• Improve Default mode prompt (less confusion with Plan mode) (#10545)

  ## Summary
  
  This PR updates `request_user_input` behavior and Default-mode guidance
  to match current collaboration-mode semantics and reduce model
  confusion.
  
  ## Why
  
  - `request_user_input` should be explicitly documented as **Plan-only**.
  - Tool description and runtime availability checks should be driven by
  the **same centralized mode policy**.
  - Default mode prompt needed stronger execution guidance and explicit
  instruction that `request_user_input` is unavailable.
  - Error messages should report the **actual mode name** (not aliases
  that can read as misleading).
  
  ## What changed
  
  - Centralized `request_user_input` mode policy in `core` handler logic:
    - Added a single allowed-modes config (`Plan` only).
    - Reused that policy for:
      - runtime rejection messaging
      - tool description text
  - Updated tool description to include availability constraint:
    - `"This tool is only available in Plan mode."`
  - Updated runtime rejection behavior:
    - `Default` -> `"request_user_input is unavailable in Default mode"`
    - `Execute` -> `"request_user_input is unavailable in Execute mode"`
  - `PairProgramming` -> `"request_user_input is unavailable in Pair
  Programming mode"`
  - Strengthened Default collaboration prompt:
    - Added explicit execution-first behavior
    - Added assumptions-first guidance
    - Added explicit `request_user_input` unavailability instruction
    - Added concise progress-reporting expectations
  - Simplified formatting implementation:
    - Inlined allowed-mode name collection into `format_allowed_modes()`
  - Kept `format_allowed_modes()` output for 3+ modes as CSV style
  (`modes: a,b,c`)

• Cleanup collaboration mode variants (#10404)

  ## Summary
  
  This PR simplifies collaboration modes to the visible set `default |
  plan`, while preserving backward compatibility for older partners that
  may still send legacy mode
  names.
  
  Specifically:
  - Renames the old Code behavior to **Default**.
  - Keeps **Plan** as-is.
  - Removes **Custom** mode behavior (fallbacks now resolve to Default).
  - Keeps `PairProgramming` and `Execute` internally for compatibility
  plumbing, while removing them from schema/API and UI visibility.
  - Adds legacy input aliasing so older clients can still send old mode
  names.
  
  ## What Changed
  
  1. Mode enum and compatibility
  - `ModeKind` now uses `Plan` + `Default` as active/public modes.
  - `ModeKind::Default` deserialization accepts legacy values:
    - `code`
    - `pair_programming`
    - `execute`
    - `custom`
  - `PairProgramming` and `Execute` variants remain in code but are hidden
  from protocol/schema generation.
  - `Custom` variant is removed; previous custom fallbacks now map to
  `Default`.
  
  2. Collaboration presets and templates
  - Built-in presets now return only:
    - `Plan`
    - `Default`
  - Template rename:
    - `core/templates/collaboration_mode/code.md` -> `default.md`
  - `execute.md` and `pair_programming.md` remain on disk but are not
  surfaced in visible preset lists.
  
  3. TUI updates
  - Updated user-facing naming and prompts from “Code” to “Default”.
  - Updated mode-cycle and indicator behavior to reflect only visible
  `Plan` and `Default`.
  - Updated corresponding tests and snapshots.
  
  4. request_user_input behavior
  - `request_user_input` remains allowed only in `Plan` mode.
  - Rejection messaging now consistently treats non-plan modes as
  `Default`.
  
  5. Schemas
  - Regenerated config and app-server schemas.
  - Public schema types now advertise mode values as:
    - `plan`
    - `default`
  
  ## Backward Compatibility Notes
  
  - Incoming legacy mode names (`code`, `pair_programming`, `execute`,
  `custom`) are accepted and coerced to `default`.
  - Outgoing/public schema surfaces intentionally expose only `plan |
  default`.
  - This allows tolerant ingestion of older partner payloads while
  standardizing new integrations on the reduced mode set.

• Trim compaction input (#10374)

  Two fixes:
  
  1. Include trailing tool output in the total context size calculation.
  Otherwise when checking whether compaction should run we ignore newly
  added outputs.
  2. Trim trailing tool output/tool calls until we can fit the request
  into the model context size. Otherwise the compaction endpoint will fail
  to compact. We only trim items that can be reproduced again by the model
  (tool calls, tool call outputs).

• [Codex][CLI] Gate image inputs by model modalities (#10271)

  ###### Summary
  
  - Add input_modalities to model metadata so clients can determine
  supported input types.
  - Gate image paste/attach in TUI when the selected model does not
  support images.
  - Block submits that include images for unsupported models and show a
  clear warning.
  - Propagate modality metadata through app-server protocol/model-list
  responses.
    - Update related tests/fixtures.
  
    ###### Rationale
  
    - Models support different input modalities.
  - Clients need an explicit capability signal to prevent unsupported
  requests.
  - Backward-compatible defaults preserve existing behavior when modality
  metadata is absent.
  
    ###### Scope
  
    - codex-rs/protocol, codex-rs/core, codex-rs/tui
    - codex-rs/app-server-protocol, codex-rs/app-server
    - Generated app-server types / schema fixtures
  
    ###### Trade-offs
  
  - Default behavior assumes text + image when field is absent for
  compatibility.
    - Server-side validation remains the source of truth.
  
    ###### Follow-up
  
  - Non-TUI clients should consume input_modalities to disable unsupported
  attachments.
  - Model catalogs should explicitly set input_modalities for text-only
  models.
  
    ###### Testing
  
    - cargo fmt --all
    - cargo test -p codex-tui
    - env -u GITHUB_APP_KEY cargo test -p codex-core --lib
    - just write-app-server-schema
  - cargo run -p codex-cli --bin codex -- app-server generate-ts --out
  app-server-types
    - test against local backend

• feat: replace custom mcp-types crate with equivalents from rmcp (#10349)

  We started working with MCP in Codex before
  https://crates.io/crates/rmcp was mature, so we had our own crate for
  MCP types that was generated from the MCP schema:
  
  
  https://github.com/openai/codex/blob/8b95d3e082376f4cb23e92641705a22afb28a9da/codex-rs/mcp-types/README.md
  
  Now that `rmcp` is more mature, it makes more sense to use their MCP
  types in Rust, as they handle details (like the `_meta` field) that our
  custom version ignored. Though one advantage that our custom types had
  is that our generated types implemented `JsonSchema` and `ts_rs::TS`,
  whereas the types in `rmcp` do not. As such, part of the work of this PR
  is leveraging the adapters between `rmcp` types and the serializable
  types that are API for us (app server and MCP) introduced in #10356.
  
  Note this PR results in a number of changes to
  `codex-rs/app-server-protocol/schema`, which merit special attention
  during review. We must ensure that these changes are still
  backwards-compatible, which is possible because we have:
  
  ```diff
  - export type CallToolResult = { content: Array<ContentBlock>, isError?: boolean, structuredContent?: JsonValue, };
  + export type CallToolResult = { content: Array<JsonValue>, structuredContent?: JsonValue, isError?: boolean, _meta?: JsonValue, };
  ```
  
  so `ContentBlock` has been replaced with the more general `JsonValue`.
  Note that `ContentBlock` was defined as:
  
  ```typescript
  export type ContentBlock = TextContent | ImageContent | AudioContent | ResourceLink | EmbeddedResource;
  ```
  
  so the deletion of those individual variants should not be a cause of
  great concern.
  
  Similarly, we have the following change in
  `codex-rs/app-server-protocol/schema/typescript/Tool.ts`:
  
  ```
  - export type Tool = { annotations?: ToolAnnotations, description?: string, inputSchema: ToolInputSchema, name: string, outputSchema?: ToolOutputSchema, title?: string, };
  + export type Tool = { name: string, title?: string, description?: string, inputSchema: JsonValue, outputSchema?: JsonValue, annotations?: JsonValue, icons?: Array<JsonValue>, _meta?: JsonValue, };
  ```
  
  so:
  
  - `annotations?: ToolAnnotations` ➡️ `JsonValue`
  - `inputSchema: ToolInputSchema` ➡️ `JsonValue`
  - `outputSchema?: ToolOutputSchema` ➡️ `JsonValue`
  
  and two new fields: `icons?: Array<JsonValue>, _meta?: JsonValue`

• chore: rename ChatGpt -> Chatgpt in type names (#10244)

  When using ChatGPT in names of types, we should be consistent, so this
  renames some types with `ChatGpt` in the name to `Chatgpt`. From
  https://rust-lang.github.io/api-guidelines/naming.html:
  
  > In `UpperCamelCase`, acronyms and contractions of compound words count
  as one word: use `Uuid` rather than `UUID`, `Usize` rather than `USize`
  or `Stdin` rather than `StdIn`. In `snake_case`, acronyms and
  contractions are lower-cased: `is_xid_start`.
  
  This PR updates existing uses of `ChatGpt` and changes them to
  `Chatgpt`. Though in all cases where it could affect the wire format, I
  visually inspected that we don't change anything there. That said, this
  _will_ change the codegen because it will affect the spelling of type
  names.
  
  For example, this renames `AuthMode::ChatGPT` to `AuthMode::Chatgpt` in
  `app-server-protocol`, but the wire format is still `"chatgpt"`.
  
  This PR also updates a number of types in `codex-rs/core/src/auth.rs`.

• Plan mode: stream proposed plans, emit plan items, and render in TUI (#9786)

  ## Summary
  - Stream proposed plans in Plan Mode using `<proposed_plan>` tags parsed
  in core, emitting plan deltas plus a plan `ThreadItem`, while stripping
  tags from normal assistant output.
  - Persist plan items and rebuild them on resume so proposed plans show
  in thread history.
  - Wire plan items/deltas through app-server protocol v2 and render a
  dedicated proposed-plan view in the TUI, including the “Implement this
  plan?” prompt only when a plan item is present.
  
  ## Changes
  
  ### Core (`codex-rs/core`)
  - Added a generic, line-based tag parser that buffers each line until it
  can disprove a tag prefix; implements auto-close on `finish()` for
  unterminated tags. `codex-rs/core/src/tagged_block_parser.rs`
  - Refactored proposed plan parsing to wrap the generic parser.
  `codex-rs/core/src/proposed_plan_parser.rs`
  - In plan mode, stream assistant deltas as:
    - **Normal text** → `AgentMessageContentDelta`
    - **Plan text** → `PlanDelta` + `TurnItem::Plan` start/completion  
    (`codex-rs/core/src/codex.rs`)
  - Final plan item content is derived from the completed assistant
  message (authoritative), not necessarily the concatenated deltas.
  - Strips `<proposed_plan>` blocks from assistant text in plan mode so
  tags don’t appear in normal messages.
  (`codex-rs/core/src/stream_events_utils.rs`)
  - Persist `ItemCompleted` events only for plan items for rollout replay.
  (`codex-rs/core/src/rollout/policy.rs`)
  - Guard `update_plan` tool in Plan Mode with a clear error message.
  (`codex-rs/core/src/tools/handlers/plan.rs`)
  - Updated Plan Mode prompt to:  
    - keep `<proposed_plan>` out of non-final reasoning/preambles  
    - require exact tag formatting  
    - allow only one `<proposed_plan>` block per turn  
    (`codex-rs/core/templates/collaboration_mode/plan.md`)
  
  ### Protocol / App-server protocol
  - Added `TurnItem::Plan` and `PlanDeltaEvent` to core protocol items.
  (`codex-rs/protocol/src/items.rs`, `codex-rs/protocol/src/protocol.rs`)
  - Added v2 `ThreadItem::Plan` and `PlanDeltaNotification` with
  EXPERIMENTAL markers and note that deltas may not match the final plan
  item. (`codex-rs/app-server-protocol/src/protocol/v2.rs`)
  - Added plan delta route in app-server protocol common mapping.
  (`codex-rs/app-server-protocol/src/protocol/common.rs`)
  - Rebuild plan items from persisted `ItemCompleted` events on resume.
  (`codex-rs/app-server-protocol/src/protocol/thread_history.rs`)
  
  ### App-server
  - Forward plan deltas to v2 clients and map core plan items to v2 plan
  items. (`codex-rs/app-server/src/bespoke_event_handling.rs`,
  `codex-rs/app-server/src/codex_message_processor.rs`)
  - Added v2 plan item tests.
  (`codex-rs/app-server/tests/suite/v2/plan_item.rs`)
  
  ### TUI
  - Added a dedicated proposed plan history cell with special background
  and padding, and moved “• Proposed Plan” outside the highlighted block.
  (`codex-rs/tui/src/history_cell.rs`, `codex-rs/tui/src/style.rs`)
  - Only show “Implement this plan?” when a plan item exists.
  (`codex-rs/tui/src/chatwidget.rs`,
  `codex-rs/tui/src/chatwidget/tests.rs`)

  - Updated protocol docs to mention plan deltas.
  (`codex-rs/docs/protocol_v1.md`)
  - Minor plumbing updates in exec/debug clients to tolerate plan deltas.
  (`codex-rs/debug-client/src/reader.rs`, `codex-rs/exec/...`)
  
  ## Tests
  - Added core integration tests:
    - Plan mode strips plan from agent messages.
    - Missing `</proposed_plan>` closes at end-of-message.  
    (`codex-rs/core/tests/suite/items.rs`)
  - Added unit tests for generic tag parser (prefix buffering, non-tag
  lines, auto-close). (`codex-rs/core/src/tagged_block_parser.rs`)
  - Existing app-server plan item tests in v2.
  (`codex-rs/app-server/tests/suite/v2/plan_item.rs`)
  
  ## Notes / Behavior
  - Plan output no longer appears in standard assistant text in Plan Mode;
  it streams via `PlanDelta` and completes as a `TurnItem::Plan`.
  - The final plan item content is authoritative and may diverge from
  streamed deltas (documented as experimental).
  - Reasoning summaries are not filtered; prompt instructs the model not
  to include `<proposed_plan>` outside the final plan message.

• Conversation naming (#8991)

  Session renaming:
  - `/rename my_session`
  - `/rename` without arg and passing an argument in `customViewPrompt`
  - AppExitInfo shows resume hint using the session name if set instead of
  uuid, defaults to uuid if not set
  - Names are stored in `CODEX_HOME/sessions.jsonl`
  
  Session resuming:
  - codex resume <name> lookup for `CODEX_HOME/sessions.jsonl` first entry
  matching the name and resumes the session

  ## Summary
  Let's dial in this api contract in a bit more with more robust fallback
  behavior when model_instructions_template is false.
  
  Switches to a more explicit template / variables structure, with more
  fallbacks.
  
  ## Testing
  - [x] Adding unit tests
  - [x] Tested locally

• feat(app-server): support external auth mode (#10012)

  This enables a new use case where `codex app-server` is embedded into a
  parent application that will directly own the user's ChatGPT auth
  lifecycle, which means it owns the user’s auth tokens and refreshes it
  when necessary. The parent application would just want a way to pass in
  the auth tokens for codex to use directly.
  
  The idea is that we are introducing a new "auth mode" currently only
  exposed via app server: **`chatgptAuthTokens`** which consist of the
  `id_token` (stores account metadata) and `access_token` (the bearer
  token used directly for backend API calls). These auth tokens are only
  stored in-memory. This new mode is in addition to the existing `apiKey`
  and `chatgpt` auth modes.
  
  This PR reuses the shape of our existing app-server account APIs as much
  as possible:
  - Update `account/login/start` with a new `chatgptAuthTokens` variant,
  which will allow the client to pass in the tokens and have codex
  app-server use them directly. Upon success, the server emits
  `account/login/completed` and `account/updated` notifications.
  - A new server->client request called
  `account/chatgptAuthTokens/refresh` which the server can use whenever
  the access token previously passed in has expired and it needs a new one
  from the parent application.
  
  I leveraged the core 401 retry loop which typically triggers auth token
  refreshes automatically, but made it pluggable:
  - **chatgpt** mode refreshes internally, as usual.
  - **chatgptAuthTokens** mode calls the client via
  `account/chatgptAuthTokens/refresh`, the client responds with updated
  tokens, codex updates its in-memory auth, then retries. This RPC has a
  10s timeout and handles JSON-RPC errors from the client.
  
  Also some additional things:
  - chatgpt logins are blocked while external auth is active (have to log
  out first. typically clients will pick one OR the other, not support
  both)
  - `account/logout` clears external auth in memory
  - Ensures that if `forced_chatgpt_workspace_id` is set via the user's
  config, we respect it in both:
  - `account/login/start` with `chatgptAuthTokens` (returns a JSON-RPC
  error back to the client)
  - `account/chatgptAuthTokens/refresh` (fails the turn, and on next
  request app-server will send another `account/chatgptAuthTokens/refresh`
  request to the client).

  we can't use runfiles directory on Windows due to path lengths, so swap

  format is changing in Bazel upstream, so pull in the official Rust
  library (via a small hack to make it importable...) and cleanup all the
  associated logic to work cleanly in both bazel and cargo without extra
  confusion

• chore: deprecate old web search feature flags (#10097)

  deprecate all old web search flags and aliases, including:
  - `[features].web_search_request` and `[features].web_search_cached`
  - `[tools].web_search`
  - `[features].web_search`
  
  slightly rework `legacy_usages` to enable pointing to non-features from
  deprecated features; we need to point to `web_search` (not under
  `[features]`) from things like `[features].web_search_cached` and
  `[features].web_search_request`.
  
  Added integration tests to confirm deprecation notice is shown on
  explicit enablement and disablement of deprecated flags.
