• fix(core): prevent hanging turn/start due to websocket warming issues (#14838)

  ## Description
  
  This PR fixes a bad first-turn failure mode in app-server when the
  startup websocket prewarm hangs. Before this change, `initialize ->
  thread/start -> turn/start` could sit behind the prewarm for up to five
  minutes, so the client would not see `turn/started`, and even
  `turn/interrupt` would block because the turn had not actually started
  yet.
  
  Now, we:
  - set a (configurable) timeout of 15s for websocket startup time,
  exposed as `websocket_startup_timeout_ms` in config.toml
  - `turn/started` is sent immediately on `turn/start` even if the
  websocket is still connecting
  - `turn/interrupt` can be used to cancel a turn that is still waiting on
  the websocket warmup
  - the turn task will wait for the full 15s websocket warming timeout
  before falling back
  
  ## Why
  
  The old behavior made app-server feel stuck at exactly the moment the
  client expects turn lifecycle events to start flowing. That was
  especially painful for external clients, because from their point of
  view the server had accepted the request but then went silent for
  minutes.
  
  ## Configuring the websocket startup timeout
  Can set it in config.toml like this:
  ```
  [model_providers.openai]
  supports_websockets = true
  websocket_connect_timeout_ms = 15000
  ```

• chore(otel): rename OtelManager to SessionTelemetry (#13808)

  ## Summary
  This is a purely mechanical refactor of `OtelManager` ->
  `SessionTelemetry` to better convey what the struct is doing. No
  behavior change.
  
  ## Why
  
  `OtelManager` ended up sounding much broader than what this type
  actually does. It doesn't manage OTEL globally; it's the session-scoped
  telemetry surface for emitting log/trace events and recording metrics
  with consistent session metadata (`app_version`, `model`, `slug`,
  `originator`, etc.).
  
  `SessionTelemetry` is a more accurate name, and updating the call sites
  makes that boundary a lot easier to follow.
  
  ## Validation
  
  - `just fmt`
  - `cargo test -p codex-otel`
  - `cargo test -p codex-core`

• Use model catalog default for reasoning summary fallback (#12873)

  ## Summary
  - make `Config.model_reasoning_summary` optional so unset means use
  model default
  - resolve the optional config value to a concrete summary when building
  `TurnContext`
  - add protocol support for `default_reasoning_summary` in model metadata
  
  ## Validation
  - `cargo test -p codex-core --lib client::tests -- --nocapture`

• 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`

• turn metadata: per-turn non-blocking (#11677)

  6c0a924203
• Remove test-support feature from codex-core and replace it with explicit test toggles (#11405)

  ## Why
  
  `codex-core` was being built in multiple feature-resolved permutations
  because test-only behavior was modeled as crate features. For a large
  crate, those permutations increase compile cost and reduce cache reuse.
  
  ## Net Change
  
  - Removed the `test-support` crate feature and related feature wiring so
  `codex-core` no longer needs separate feature shapes for test consumers.
  - Standardized cross-crate test-only access behind
  `codex_core::test_support`.
  - External test code now imports helpers from
  `codex_core::test_support`.
  - Underlying implementation hooks are kept internal (`pub(crate)`)
  instead of broadly public.
  
  ## Outcome
  
  - Fewer `codex-core` build permutations.
  - Better incremental cache reuse across test targets.
  - No intended production behavior change.

• 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`.

• chore: migrate from Config::load_from_base_config_with_overrides to ConfigBuilder (#8276)

  https://github.com/openai/codex/pull/8235 introduced `ConfigBuilder` and
  this PR updates all call non-test call sites to use it instead of
  `Config::load_from_base_config_with_overrides()`.
  
  This is important because `load_from_base_config_with_overrides()` uses
  an empty `ConfigRequirements`, which is a reasonable default for testing
  so the tests are not influenced by the settings on the host. This method
  is now guarded by `#[cfg(test)]` so it cannot be used by business logic.
  
  Because `ConfigBuilder::build()` is `async`, many of the test methods
  had to be migrated to be `async`, as well. On the bright side, this made
  it possible to eliminate a bunch of `block_on_future()` stuff.

• Delegate review to codex instance (#5572)

  In this PR, I am exploring migrating task kind to an invocation of
  Codex. The main reason would be getting rid off multiple
  `ConversationHistory` state and streamlining our context/history
  management.
  
  This approach depends on opening a channel between the sub-codex and
  codex. This channel is responsible for forwarding `interactive`
  (`approvals`) and `non-interactive` events. The `task` is responsible
  for handling those events.
  
  This opens the door for implementing `codex as a tool`, replacing
  `compact` and `review`, and potentially subagents.
  
  One consideration is this code is very similar to `app-server` specially
  in the approval part. If in the future we wanted an interactive
  `sub-codex` we should consider using `codex-mcp`

• feat: add experimental_bearer_token option to model provider definition (#5467)

  While we do not want to encourage users to hardcode secrets in their
  `config.toml` file, it should be possible to pass an API key
  programmatically. For example, when using `codex app-server`, it is
  possible to pass a "bag of configuration" as part of the
  `NewConversationParams`:
  
  https://github.com/openai/codex/blob/682d05512f2992dd0657f1078d4146f15c744d7a/codex-rs/app-server-protocol/src/protocol.rs#L248-L251
  
  When using `codex app-server`, it's not practical to change env vars of
  the `codex app-server` process on the fly (which is how we usually read
  API key values), so this helps with that.
