• fix(core) Preserve base_instructions in SessionMeta (#9427)

  ## Summary
  This PR consolidates base_instructions onto SessionMeta /
  SessionConfiguration, so we ensure `base_instructions` is set once per
  session and should be (mostly) immutable, unless:
  - overridden by config on resume / fork
  - sub-agent tasks, like review or collab
  
  
  In a future PR, we should convert all references to `base_instructions`
  to consistently used the typed struct, so it's less likely that we put
  other strings there. See #9423. However, this PR is already quite
  complex, so I'm deferring that to a follow-up.
  
  ## Testing
  - [x] Added a resume test to assert that instructions are preserved. In
  particular, `resume_switches_models_preserves_base_instructions` fails
  against main.
  
  Existing test coverage thats assert base instructions are preserved
  across multiple requests in a session:
  - Manual compact keeps baseline instructions:
  core/tests/suite/compact.rs:199
  - Auto-compact keeps baseline instructions:
  core/tests/suite/compact.rs:1142
  - Prompt caching reuses the same instructions across two requests:
  core/tests/suite/prompt_caching.rs:150 and
  core/tests/suite/prompt_caching.rs:157
  - Prompt caching with explicit expected string across two requests:
  core/tests/suite/prompt_caching.rs:213 and
  core/tests/suite/prompt_caching.rs:222
  - Resume with model switch keeps original instructions:
  core/tests/suite/resume.rs:136
  - Compact/resume/fork uses request 0 instructions for later expected
  payloads: core/tests/suite/compact_resume_fork.rs:215

• Migrate tui to use UserTurn (#9497)

  - `tui/` and `tui2/` submit `Op::UserTurn` and own full turn context
  (cwd/approval/sandbox/model/etc.).
  - `Op::UserInput` is documented as legacy in `codex-protocol` (doc-only;
  no `#[deprecated]` to avoid `-D warnings` fallout).
  - Remove obsolete `#[allow(deprecated)]` and the unused `ConversationId`
  alias/re-export.

• chore(instructions) Remove unread SessionMeta.instructions field (#9423)

  ### Description
  - Remove the now-unused `instructions` field from the session metadata
  to simplify SessionMeta and stop propagating transient instruction text
  through the rollout recorder API. This was only saving
  user_instructions, and was never being read.
  - Stop passing user instructions into the rollout writer at session
  creation so the rollout header only contains canonical session metadata.
  
  ### Testing
  
  - Ran `just fmt` which completed successfully.
  - Ran `just fix -p codex-protocol`, `just fix -p codex-core`, `just fix
  -p codex-app-server`, `just fix -p codex-tui`, and `just fix -p
  codex-tui2` which completed (Clippy fixes applied) as part of
  verification.
  - Ran `cargo test -p codex-protocol` which passed (28 tests).
  - Ran `cargo test -p codex-core` which showed failures in a small set of
  tests (not caused by the protocol type change directly):
  `default_client::tests::test_create_client_sets_default_headers`,
  several `models_manager::manager::tests::refresh_available_models_*`,
  and `shell_snapshot::tests::linux_sh_snapshot_includes_sections` (these
  tests failed in this CI run).
  - Ran `cargo test -p codex-app-server` which reported several failing
  integration tests (including
  `suite::codex_message_processor_flow::test_codex_jsonrpc_conversation_flow`,
  `suite::output_schema::send_user_turn_*`, and
  `suite::user_agent::get_user_agent_returns_current_codex_user_agent`).
  - `cargo test -p codex-tui` and `cargo test -p codex-tui2` were
  attempted but aborted due to disk space exhaustion (`No space left on
  device`).

• Support SKILL.toml file. (#9125)

  We’re introducing a new SKILL.toml to hold skill metadata so Codex can
  deliver a richer Skills experience.
  
  Initial focus is the interface block:
  ```
  [interface]
  display_name = "Optional user-facing name"
  short_description = "Optional user-facing description"
  icon_small = "./assets/small-400px.png"
  icon_large = "./assets/large-logo.svg"
  brand_color = "#3B82F6"
  default_prompt = "Optional surrounding prompt to use the skill with"
  ```
  
  All fields are exposed via the app server API.
  display_name and short_description are consumed by the TUI.

• feat: add support for read-only bind mounts in the linux sandbox (#9112)

  ### Motivation
  
  - Landlock alone cannot prevent writes to sensitive in-repo files like
  `.git/` when the repo root is writable, so explicit mount restrictions
  are required for those paths.
  - The sandbox must set up any mounts before calling Landlock so Landlock
  can still be applied afterwards and the two mechanisms compose
  correctly.
  
  ### Description
  
  - Add a new `linux-sandbox` helper `apply_read_only_mounts` in
  `linux-sandbox/src/mounts.rs` that: unshares namespaces, maps uids/gids
  when required, makes mounts private, bind-mounts targets, and remounts
  them read-only.
  - Wire the mount step into the sandbox flow by calling
  `apply_read_only_mounts(...)` before network/seccomp and before applying
  Landlock rules in `linux-sandbox/src/landlock.rs`.

  ### Summary
  * Added `mcpServer/refresh` command to inform app servers and active
  threads to refresh mcpServer on next turn event.
  * Added `pending_mcp_server_refresh_config` to codex core so that if the
  value is populated, we reinitialize the mcp server manager on the thread
  level.
  * The config is updated on `mcpServer/refresh` command which we iterate
  through threads and provide with the latest config value after last
  write.

• feat: add wait tool implementation for collab (#9088)

  Add implementation for the `wait` tool.
  
  For this we consider all status different from `PendingInit` and
  `Running` as terminal. The `wait` tool call will return either after a
  given timeout or when the tool reaches a non-terminal status.
  
  A few points to note:
  * The usage of a channel is preferred to prevent some races (just
  looping on `get_status()` could "miss" a terminal status)
  * The order of operations is very important, we need to first subscribe
  and then check the last known status to prevent race conditions
  * If the channel gets dropped, we return an error on purpose

• feat(app-server): thread/rollback API (#8454)

  Add `thread/rollback` to app-server to support IDEs undo-ing the last N
  turns of a thread.
  
  For context, an IDE partner will be supporting an "undo" capability
  where the IDE (the app-server client) will be responsible for reverting
  the local changes made during the last turn. To support this well, we
  also need a way to drop the last turn (or more generally, the last N
  turns) from the agent's context. This is what `thread/rollback` does.
  
  **Core idea**: A Thread rollback is represented as a persisted event
  message (EventMsg::ThreadRollback) in the rollout JSONL file, not by
  rewriting history. On resume, both the model's context (core replay) and
  the UI turn list (app-server v2's thread history builder) apply these
  markers so the pruned history is consistent across live conversations
  and `thread/resume`.
  
  Implementation notes:
  - Rollback only affects agent context and appends to the rollout file;
  clients are responsible for reverting files on disk.
  - If a thread rollback is currently in progress, subsequent
  `thread/rollback` calls are rejected.
  - Because we use `CodexConversation::submit` and codex core tracks
  active turns, returning an error on concurrent rollbacks is communicated
  via an `EventMsg::Error` with a new variant
  `CodexErrorInfo::ThreadRollbackFailed`. app-server watches for that and
  sends the BAD_REQUEST RPC response.
  
  Tests cover thread rollbacks in both core and app-server, including when
  `num_turns` > existing turns (which clears all turns).
  
  **Note**: this explicitly does **not** behave like `/undo` which we just
  removed from the CLI, which does the opposite of what `thread/rollback`
  does. `/undo` reverts local changes via ghost commits/snapshots and does
  not modify the agent's context / conversation history.

• feat: expose outputSchema to user_turn/turn_start app_server API (#8377)

  What changed
  - Added `outputSchema` support to the app-server APIs, mirroring `codex
  exec --output-schema` behavior.
  - V1 `sendUserTurn` now accepts `outputSchema` and constrains the final
  assistant message for that turn.
  - V2 `turn/start` now accepts `outputSchema` and constrains the final
  assistant message for that turn (explicitly per-turn only).
  
  Core behavior
  - `Op::UserTurn` already supported `final_output_json_schema`; now V1
  `sendUserTurn` forwards `outputSchema` into that field.
  - `Op::UserInput` now carries `final_output_json_schema` for per-turn
  settings updates; core maps it into
  `SessionSettingsUpdate.final_output_json_schema` so it applies to the
  created turn context.
  - V2 `turn/start` does NOT persist the schema via `OverrideTurnContext`
  (it’s applied only for the current turn). Other overrides
  (cwd/model/etc) keep their existing persistent behavior.
  
  API / docs
  - `codex-rs/app-server-protocol/src/protocol/v1.rs`: add `output_schema:
  Option<serde_json::Value>` to `SendUserTurnParams` (serialized as
  `outputSchema`).
  - `codex-rs/app-server-protocol/src/protocol/v2.rs`: add `output_schema:
  Option<JsonValue>` to `TurnStartParams` (serialized as `outputSchema`).
  - `codex-rs/app-server/README.md`: document `outputSchema` for
  `turn/start` and clarify it applies only to the current turn.
  - `codex-rs/docs/codex_mcp_interface.md`: document `outputSchema` for v1
  `sendUserTurn` and v2 `turn/start`.
  
  Tests added/updated
  - New app-server integration tests asserting `outputSchema` is forwarded
  into outbound `/responses` requests as `text.format`:
    - `codex-rs/app-server/tests/suite/output_schema.rs`
    - `codex-rs/app-server/tests/suite/v2/output_schema.rs`
  - Added per-turn semantics tests (schema does not leak to the next
  turn):
    - `send_user_turn_output_schema_is_per_turn_v1`
    - `turn_start_output_schema_is_per_turn_v2`
  - Added protocol wire-compat tests for the merged op:
    - serialize omits `final_output_json_schema` when `None`
    - deserialize works when field is missing
    - serialize includes `final_output_json_schema` when `Some(schema)`
  
  Call site updates (high level)
  - Updated all `Op::UserInput { .. }` constructions to include
  `final_output_json_schema`:
    - `codex-rs/app-server/src/codex_message_processor.rs`
    - `codex-rs/core/src/codex_delegate.rs`
    - `codex-rs/mcp-server/src/codex_tool_runner.rs`
    - `codex-rs/tui/src/chatwidget.rs`
    - `codex-rs/tui2/src/chatwidget.rs`
    - plus impacted core tests.
  
  Validation
  - `just fmt`

• Account for last token count on resume (#8677)

  last token count in context manager is initialized to 0. Gets populated
  only on events from server.
  
  This PR populates it on resume so we can decide if we need to compact or
  not.

• [chore] add additional_details to StreamErrorEvent + wire through (#8307)

  ### What
  
  Builds on #8293.
  
  Add `additional_details`, which contains the upstream error message, to
  relevant structures used to pass along retryable `StreamError`s.
  
  Uses the new TUI status indicator's `details` field (shows under the
  status header) to display the `additional_details` error to the user on
  retryable `Reconnecting...` errors. This adds clarity for users for
  retryable errors.
  
  Will make corresponding change to VSCode extension to show
  `additional_details` as expandable from the `Reconnecting...` cell.
  
  Examples:

• chore: save more about turn context in rollout log file (#8458)

  ### Motivation
  - Persist richer per-turn configuration in rollouts so resumed/forked
  sessions and tooling can reason about the exact instruction inputs and
  output constraints used for a turn.
  
  ### Description
  - Extend `TurnContextItem` to include optional `base_instructions`,
  `user_instructions`, and `developer_instructions`.
  - Record the optional `final_output_json_schema` associated with a turn.
  - Add an optional `truncation_policy` to `TurnContextItem` and populate
  it when writing turn-context rollout items.
  - Introduce a protocol-level `TruncationPolicy` representation and
  convert from core truncation policy when recording.
  
  ### Testing
  - `cargo test -p codex-protocol` (pass)

• feat: introduce ExternalSandbox policy (#8290)

  ## Description
  
  Introduced `ExternalSandbox` policy to cover use case when sandbox
  defined by outside environment, effectively it translates to
  `SandboxMode#DangerFullAccess` for file system (since sandbox configured
  on container level) and configurable `network_access` (either Restricted
  or Enabled by outside environment).
  
  as example you can configure `ExternalSandbox` policy as part of
  `sendUserTurn` v1 app_server API:
  
  ```
   {
              "conversationId": <id>,
              "cwd": <cwd>,
              "approvalPolicy": "never",
              "sandboxPolicy": {
                    "type": ""external-sandbox",
                    "network_access": "enabled"/"restricted"
              },
              "model": <model>,
              "effort": <effort>,
              ....
          }

• Add public skills + improve repo skill discovery and error UX (#8098)

  1. Adds SkillScope::Public end-to-end (core + protocol) and loads skills
  from the public cache directory
  2. Improves repo skill discovery by searching upward for the nearest
  .codex/skills within a git repo
  3. Deduplicates skills by name with deterministic ordering to avoid
  duplicates across sources
  4. Fixes garbled “Skill errors” overlay rendering by preventing pending
  history lines from being injected during the modal
  5. Updates the project docs “Skills” intro wording to avoid hardcoded
  paths

• feat: if .codex is a sub-folder of a writable root, then make it read-only to the sandbox (#8088)

  In preparation for in-repo configuration support, this updates
  `WritableRoot::get_writable_roots_with_cwd()` to include the `.codex`
  subfolder in `WritableRoot.read_only_subpaths`, if it exists, as we
  already do for `.git`.
  
  As noted, currently, like `.git`, `.codex` will only be read-only under
  macOS Seatbelt, but we plan to bring support to other OSes, as well.
  
  Updated the integration test in `seatbelt.rs` so that it actually
  attempts to run the generated Seatbelt commands, verifying that:
  
  - trying to write to `.codex/config.toml` in a writable root fails
  - trying to write to `.git/hooks/pre-commit` in a writable root fails
  - trying to write to the writable root containing the `.codex` and
  `.git` subfolders succeeds

• Reimplement skills loading using SkillsManager + skills/list op. (#7914)

  refactor the way we load and manage skills:
  1. Move skill discovery/caching into SkillsManager and reuse it across
  sessions.
  2. Add the skills/list API (Op::ListSkills/SkillsListResponse) to fetch
  skills for one or more cwds. Also update app-server for VSCE/App;
  3. Trigger skills/list during session startup so UIs preload skills and
  handle errors immediately.

• fix: introduce AbsolutePathBuf as part of sandbox config (#7856)

  Changes the `writable_roots` field of the `WorkspaceWrite` variant of
  the `SandboxPolicy` enum from `Vec<PathBuf>` to `Vec<AbsolutePathBuf>`.
  This is helpful because now callers can be sure the value is an absolute
  path rather than a relative one. (Though when using an absolute path in
  a Seatbelt config policy, we still have to _canonicalize_ it first.)
  
  Because `writable_roots` can be read from a config file, it is important
  that we are able to resolve relative paths properly using the parent
  folder of the config file as the base path.

• Inject SKILL.md when it's explicitly mentioned. (#7763)

  1. Skills load once in core at session start; the cached outcome is
  reused across core and surfaced to TUI via SessionConfigured.
  2. TUI detects explicit skill selections, and core injects the matching
  SKILL.md content into the turn when a selected skill is present.

• Refactor execpolicy fallback evaluation (#7544)

  ## Refactor of the `execpolicy` crate
  
  To illustrate why we need this refactor, consider an agent attempting to
  run `apple | rm -rf ./`. Suppose `apple` is allowed by `execpolicy`.
  Before this PR, `execpolicy` would consider `apple` and `pear` and only
  render one rule match: `Allow`. We would skip any heuristics checks on
  `rm -rf ./` and immediately approve `apple | rm -rf ./` to run.
  
  To fix this, we now thread a `fallback` evaluation function into
  `execpolicy` that runs when no `execpolicy` rules match a given command.
  In our example, we would run `fallback` on `rm -rf ./` and prevent
  `apple | rm -rf ./` from being run without approval.

• whitelist command prefix integration in core and tui (#7033)

  this PR enables TUI to approve commands and add their prefixes to an

  />
  
  note: we only show the option to whitelist the command when 
  1) command is not multi-part (e.g `git add -A && git commit -m 'hello
  world'`)
  2) command is not already matched by an existing rule
