-## Lifecycle Overview
-
-- Initialize once: Immediately after launching the codex app-server process, send an `initialize` request with your client metadata, then emit an `initialized` notification. Any other request before this handshake gets rejected.
-- Start (or resume) a thread: Call `thread/start` to open a fresh conversation. The response returns the thread object and you’ll also get a `thread/started` notification. If you’re continuing an existing conversation, call `thread/resume` with its ID instead.
-- Begin a turn: To send user input, call `turn/start` with the target `threadId` and the user's input. Optional fields let you override model, cwd, sandbox policy, etc. This immediately returns the new turn object and triggers a `turn/started` notification.
-- Stream events: After `turn/start`, keep reading JSON-RPC notifications on stdout. You’ll see `item/started`, `item/completed`, deltas like `item/agentMessage/delta`, tool progress, etc. These represent streaming model output plus any side effects (commands, tool calls, reasoning notes).
-- Finish the turn: When the model is done (or the turn is interrupted via making the `turn/interrupt` call), the server sends `turn/completed` with the final turn state and token usage.
-
-## Initialization
-
-Clients must send a single `initialize` request before invoking any other method, then acknowledge with an `initialized` notification. The server returns the user agent string it will present to upstream services; subsequent requests issued before initialization receive a `"Not initialized"` error, and repeated `initialize` calls receive an `"Already initialized"` error.
-
-Example:
-

-## Core primitives
-
-We have 3 top level primitives:
-- Thread - a conversation between the Codex agent and a user. Each thread contains multiple turns.
-- Turn - one turn of the conversation, typically starting with a user message and finishing with an agent message. Each turn contains multiple items.
-- Item - represents user inputs and agent outputs as part of the turn, persisted and used as the context for future conversations.
-
-## Thread & turn endpoints
-
-The JSON-RPC API exposes dedicated methods for managing Codex conversations. Threads store long-lived conversation metadata, and turns store the per-message exchange (input → Codex output, including streamed items). Use the thread APIs to create, list, or archive sessions, then drive the conversation with turn APIs and notifications.
-
-### Quick reference
-- `thread/start` — create a new thread; emits `thread/started` and auto-subscribes you to turn/item events for that thread.
-- `thread/resume` — reopen an existing thread by id so subsequent `turn/start` calls append to it.
-- `thread/list` — page through stored rollouts; supports cursor-based pagination and optional `modelProviders` filtering.
-- `thread/archive` — move a thread’s rollout file into the archived directory; returns `{}` on success.
-- `turn/start` — add user input to a thread and begin Codex generation; responds with the initial `turn` object and streams `turn/started`, `item/*`, and `turn/completed` notifications.
-- `turn/interrupt` — request cancellation of an in-flight turn by `(thread_id, turn_id)`; success is an empty `{}` response and the turn finishes with `status: "interrupted"`.
-- `review/start` — kick off Codex’s automated reviewer for a thread; responds like `turn/start` and emits a `item/completed` notification with a `codeReview` item when results are ready.
-
-### 1) Start or resume a thread
-
-Start a fresh thread when you need a new Codex conversation.
-
-```json
-{ "method": "thread/start", "id": 10, "params": {
-    // Optionally set config settings. If not specified, will use the user's
-    // current config settings.
-    "model": "gpt-5.1-codex",
-    "cwd": "/Users/me/project",
-    "approvalPolicy": "never",
-    "sandbox": "workspaceWrite",
-} }
-{ "id": 10, "result": {
-    "thread": {
-        "id": "thr_123",
-        "preview": "",
-        "modelProvider": "openai",
-        "createdAt": 1730910000
-    }
-} }
-{ "method": "thread/started", "params": { "thread": { … } } }
-```
-
-To continue a stored session, call `thread/resume` with the `thread.id` you previously recorded. The response shape matches `thread/start`, and no additional notifications are emitted:
-
-```json
-{ "method": "thread/resume", "id": 11, "params": { "threadId": "thr_123" } }
-{ "id": 11, "result": { "thread": { "id": "thr_123", … } } }
-```
-
-### 2) List threads (pagination & filters)
-
-`thread/list` lets you render a history UI. Pass any combination of:
-- `cursor` — opaque string from a prior response; omit for the first page.
-- `limit` — server defaults to a reasonable page size if unset.
-- `modelProviders` — restrict results to specific providers; unset, null, or an empty array will include all providers.
-
-Example:
-
-```json
-{ "method": "thread/list", "id": 20, "params": {
-    "cursor": null,
-    "limit": 25,
-} }
-{ "id": 20, "result": {
-    "data": [
-        { "id": "thr_a", "preview": "Create a TUI", "modelProvider": "openai", "createdAt": 1730831111 },
-        { "id": "thr_b", "preview": "Fix tests", "modelProvider": "openai", "createdAt": 1730750000 }
-    ],
-    "nextCursor": "opaque-token-or-null"
-} }
-```
-
-When `nextCursor` is `null`, you’ve reached the final page.
-
-### 3) Archive a thread
-
-Use `thread/archive` to move the persisted rollout (stored as a JSONL file on disk) into the archived sessions directory.
-
-```json
-{ "method": "thread/archive", "id": 21, "params": { "threadId": "thr_b" } }
-{ "id": 21, "result": {} }
-```
-
-An archived thread will not appear in future calls to `thread/list`.
-
-### 4) Start a turn (send user input)
-
-Turns attach user input (text or images) to a thread and trigger Codex generation. The `input` field is a list of discriminated unions:
-
-- `{"type":"text","text":"Explain this diff"}`
-- `{"type":"image","url":"https://…png"}`
-- `{"type":"localImage","path":"/tmp/screenshot.png"}`
-
-You can optionally specify config overrides on the new turn. If specified, these settings become the default for subsequent turns on the same thread.
-
-```json
-{ "method": "turn/start", "id": 30, "params": {
-    "threadId": "thr_123",
-    "input": [ { "type": "text", "text": "Run tests" } ],
-    // Below are optional config overrides
-    "cwd": "/Users/me/project",
-    "approvalPolicy": "unlessTrusted",
-    "sandboxPolicy": {
-        "mode": "workspaceWrite",
-        "writableRoots": ["/Users/me/project"],
-        "networkAccess": true
-    },
-    "model": "gpt-5.1-codex",
-    "effort": "medium",
-    "summary": "concise"
-} }
-{ "id": 30, "result": { "turn": {
-    "id": "turn_456",
-    "status": "inProgress",
-    "items": [],
-    "error": null
-} } }
-```
-
-### 5) Interrupt an active turn
-
-You can cancel a running Turn with `turn/interrupt`.
-
-```json
-{ "method": "turn/interrupt", "id": 31, "params": {
-    "threadId": "thr_123",
-    "turnId": "turn_456"
-} }
-{ "id": 31, "result": {} }
-```
-
-The server requests cancellations for running subprocesses, then emits a `turn/completed` event with `status: "interrupted"`. Rely on the `turn/completed` to know when Codex-side cleanup is done.
-
-### 6) Request a code review
-
-Use `review/start` to run Codex’s reviewer on the currently checked-out project. The request takes the thread id plus a `target` describing what should be reviewed:
-
-- `{"type":"uncommittedChanges"}` — staged, unstaged, and untracked files.
-- `{"type":"baseBranch","branch":"main"}` — diff against the provided branch’s upstream (see prompt for the exact `git merge-base`/`git diff` instructions Codex will run).
-- `{"type":"commit","sha":"abc1234","title":"Optional subject"}` — review a specific commit.
-- `{"type":"custom","instructions":"Free-form reviewer instructions"}` — fallback prompt equivalent to the legacy manual review request.
-- `appendToOriginalThread` (bool, default `false`) — when `true`, Codex also records a final assistant-style message with the review summary in the original thread. When `false`, only the `codeReview` item is emitted for the review run and no extra message is added to the original thread.
-
-Example request/response:
-
-```json
-{ "method": "review/start", "id": 40, "params": {
-    "threadId": "thr_123",
-    "appendToOriginalThread": true,
-    "target": { "type": "commit", "sha": "1234567deadbeef", "title": "Polish tui colors" }
-} }
-{ "id": 40, "result": { "turn": {
-    "id": "turn_900",
-    "status": "inProgress",
-    "items": [
-        { "type": "userMessage", "id": "turn_900", "content": [ { "type": "text", "text": "Review commit 1234567: Polish tui colors" } ] }
-    ],
-    "error": null
-} } }
-```
-
-Codex streams the usual `turn/started` notification followed by an `item/started`
-with the same `codeReview` item id so clients can show progress:
-
-```json
-{ "method": "item/started", "params": { "item": {
-    "type": "codeReview",
-    "id": "turn_900",
-    "review": "current changes"
-} } }
-```
-
-When the reviewer finishes, the server emits `item/completed` containing the same
-`codeReview` item with the final review text:
-
-```json
-{ "method": "item/completed", "params": { "item": {
-    "type": "codeReview",
-    "id": "turn_900",
-    "review": "Looks solid overall...\n\n- Prefer Stylize helpers — app.rs:10-20\n  ..."
-} } }
-```
-
-The `review` string is plain text that already bundles the overall explanation plus a bullet list for each structured finding (matching `ThreadItem::CodeReview` in the generated schema). Use this notification to render the reviewer output in your client.
-
-## Events (work-in-progress)
-
-Event notifications are the server-initiated event stream for thread lifecycles, turn lifecycles, and the items within them. After you start or resume a thread, keep reading stdout for `thread/started`, `turn/*`, and `item/*` notifications.
-
-### Turn events
-
-The app-server streams JSON-RPC notifications while a turn is running. Each turn starts with `turn/started` (initial `turn`) and ends with `turn/completed` (final `turn` status). Token usage events stream separately via `thread/tokenUsage/updated`. Clients subscribe to the events they care about, rendering each item incrementally as updates arrive. The per-item lifecycle is always: `item/started` → zero or more item-specific deltas → `item/completed`.
-
-- `turn/started` — `{ turn }` with the turn id, empty `items`, and `status: "inProgress"`.
-- `turn/completed` — `{ turn }` where `turn.status` is `completed`, `interrupted`, or `failed`; failures carry `{ error: { message, codexErrorInfo? } }`.
-
-Today both notifications carry an empty `items` array even when item events were streamed; rely on `item/*` notifications for the canonical item list until this is fixed.
-
-#### Thread items
-
-`ThreadItem` is the tagged union carried in turn responses and `item/*` notifications. Currently we support events for the following items:
-- `userMessage` — `{id, content}` where `content` is a list of user inputs (`text`, `image`, or `localImage`).
-- `agentMessage` — `{id, text}` containing the accumulated agent reply.
-- `reasoning` — `{id, summary, content}` where `summary` holds streamed reasoning summaries (applicable for most OpenAI models) and `content` holds raw reasoning blocks (applicable for e.g. open source models).
-- `commandExecution` — `{id, command, cwd, status, commandActions, aggregatedOutput?, exitCode?, durationMs?}` for sandboxed commands; `status` is `inProgress`, `completed`, `failed`, or `declined`.
-- `fileChange` — `{id, changes, status}` describing proposed edits; `changes` list `{path, kind, diff}` and `status` is `inProgress`, `completed`, `failed`, or `declined`.
-- `mcpToolCall` — `{id, server, tool, status, arguments, result?, error?}` describing MCP calls; `status` is `inProgress`, `completed`, or `failed`.
-- `webSearch` — `{id, query}` for a web search request issued by the agent.
-- `compacted` - `{threadId, turnId}` when codex compacts the conversation history. This can happen automatically.
-
-All items emit two shared lifecycle events:
-- `item/started` — emits the full `item` when a new unit of work begins so the UI can render it immediately; the `item.id` in this payload matches the `itemId` used by deltas.
-- `item/completed` — sends the final `item` once that work finishes (e.g., after a tool call or message completes); treat this as the authoritative state.
-
-There are additional item-specific events:
-#### agentMessage
-- `item/agentMessage/delta` — appends streamed text for the agent message; concatenate `delta` values for the same `itemId` in order to reconstruct the full reply.
-#### reasoning
-- `item/reasoning/summaryTextDelta` — streams readable reasoning summaries; `summaryIndex` increments when a new summary section opens.
-- `item/reasoning/summaryPartAdded` — marks the boundary between reasoning summary sections for an `itemId`; subsequent `summaryTextDelta` entries share the same `summaryIndex`.
-- `item/reasoning/textDelta` — streams raw reasoning text (only applicable for e.g. open source models); use `contentIndex` to group deltas that belong together before showing them in the UI.
-#### commandExecution
-- `item/commandExecution/outputDelta` — streams stdout/stderr for the command; append deltas in order to render live output alongside `aggregatedOutput` in the final item.
-Final `commandExecution` items include parsed `commandActions`, `status`, `exitCode`, and `durationMs` so the UI can summarize what ran and whether it succeeded.
-#### fileChange
-`fileChange` items contain a `changes` list with `{path, kind, diff}` entries (`kind` is `add`, `delete`, or `update` with an optional `movePath`). The `status` tracks whether apply succeeded (`completed`), failed, or was `declined`.
-
-### Errors
-`error` event is emitted whenever the server hits an error mid-turn (for example, upstream model errors or quota limits). Carries the same `{ error: { message, codexErrorInfo? } }` payload as `turn.status: "failed"` and may precede that terminal notification.
-
-  `codexErrorInfo` maps to the `CodexErrorInfo` enum. Common values:
-  - `ContextWindowExceeded`
-  - `UsageLimitExceeded`
-  - `HttpConnectionFailed { httpStatusCode? }`: upstream HTTP failures including 4xx/5xx
-  - `ResponseStreamConnectionFailed { httpStatusCode? }`: failure to connect to the response SSE stream
-  - `ResponseStreamDisconnected { httpStatusCode? }`: disconnect of the response SSE stream in the middle of a turn before completion
-  - `ResponseTooManyFailedAttempts { httpStatusCode? }`
-  - `BadRequest`
-  - `Unauthorized`
-  - `SandboxError`
-  - `InternalServerError`
-  - `Other`: all unclassified errors
-
-When an upstream HTTP status is available (for example, from the Responses API or a provider), it is forwarded in `httpStatusCode` on the relevant `codexErrorInfo` variant.
-
-## Approvals
-
-Certain actions (shell commands or modifying files) may require explicit user approval depending on the user's config. When `turn/start` is used, the app-server drives an approval flow by sending a server-initiated JSON-RPC request to the client. The client must respond to tell Codex whether to proceed. UIs should present these requests inline with the active turn so users can review the proposed command or diff before choosing.
-
-- Requests include `threadId` and `turnId`—use them to scope UI state to the active conversation.
-- Respond with a single `{ "decision": "accept" | "decline" }` payload (plus optional `acceptSettings` on command executions). The server resumes or declines the work and ends the item with `item/completed`.
-
-### Command execution approvals
-
-Order of messages:
-1. `item/started` — shows the pending `commandExecution` item with `command`, `cwd`, and other fields so you can render the proposed action.
-2. `item/commandExecution/requestApproval` (request) — carries the same `itemId`, `threadId`, `turnId`, optionally `reason` or `risk`, plus `parsedCmd` for friendly display.
-3. Client response — `{ "decision": "accept", "acceptSettings": { "forSession": false } }` or `{ "decision": "decline" }`.
-4. `item/completed` — final `commandExecution` item with `status: "completed" | "failed" | "declined"` and execution output. Render this as the authoritative result.
-
-### File change approvals
-
-Order of messages:
-1. `item/started` — emits a `fileChange` item with `changes` (diff chunk summaries) and `status: "inProgress"`. Show the proposed edits and paths to the user.
-2. `item/fileChange/requestApproval` (request) — includes `itemId`, `threadId`, `turnId`, and an optional `reason`.
-3. Client response — `{ "decision": "accept" }` or `{ "decision": "decline" }`.
-4. `item/completed` — returns the same `fileChange` item with `status` updated to `completed`, `failed`, or `declined` after the patch attempt. Rely on this to show success/failure and finalize the diff state in your UI.
-
-UI guidance for IDEs: surface an approval dialog as soon as the request arrives. The turn will proceed after the server receives a response to the approval request. The terminal `item/completed` notification will be sent with the appropriate status.
-
-## Auth endpoints
-
-The JSON-RPC auth/account surface exposes request/response methods plus server-initiated notifications (no `id`). Use these to determine auth state, start or cancel logins, logout, and inspect ChatGPT rate limits.
-
-### Quick reference
-- `account/read` — fetch current account info; optionally refresh tokens.
-- `account/login/start` — begin login (`apiKey` or `chatgpt`).
-- `account/login/completed` (notify) — emitted when a login attempt finishes (success or error).
-- `account/login/cancel` — cancel a pending ChatGPT login by `loginId`.
-- `account/logout` — sign out; triggers `account/updated`.
-- `account/updated` (notify) — emitted whenever auth mode changes (`authMode`: `apikey`, `chatgpt`, or `null`).
-- `account/rateLimits/read` — fetch ChatGPT rate limits; updates arrive via `account/rateLimits/updated` (notify).
-
-### 1) Check auth state
-
-Request:
-```json
-{ "method": "account/read", "id": 1, "params": { "refreshToken": false } }
-```
-
-Response examples:
-```json
-{ "id": 1, "result": { "account": null, "requiresOpenaiAuth": false } } // No OpenAI auth needed (e.g., OSS/local models)
-{ "id": 1, "result": { "account": null, "requiresOpenaiAuth": true } }  // OpenAI auth required (typical for OpenAI-hosted models)
-{ "id": 1, "result": { "account": { "type": "apiKey" }, "requiresOpenaiAuth": true } }
-{ "id": 1, "result": { "account": { "type": "chatgpt", "email": "user@example.com", "planType": "pro" }, "requiresOpenaiAuth": true } }
-```
-
-Field notes:
-- `refreshToken` (bool): set `true` to force a token refresh.
-- `requiresOpenaiAuth` reflects the active provider; when `false`, Codex can run without OpenAI credentials.
-
-### 2) Log in with an API key
-
-1. Send:
-   ```json
-   { "method": "account/login/start", "id": 2, "params": { "type": "apiKey", "apiKey": "sk-…" } }
-   ```
-2. Expect:
-   ```json
-   { "id": 2, "result": { "type": "apiKey" } }
-   ```
-3. Notifications:
-   ```json
-   { "method": "account/login/completed", "params": { "loginId": null, "success": true, "error": null } }
-   { "method": "account/updated", "params": { "authMode": "apikey" } }
-   ```
-
-### 3) Log in with ChatGPT (browser flow)
-
-1. Start:
-   ```json
-   { "method": "account/login/start", "id": 3, "params": { "type": "chatgpt" } }
-   { "id": 3, "result": { "type": "chatgpt", "loginId": "<uuid>", "authUrl": "https://chatgpt.com/…&redirect_uri=http%3A%2F%2Flocalhost%3A<port>%2Fauth%2Fcallback" } }
-   ```
-2. Open `authUrl` in a browser; the app-server hosts the local callback.
-3. Wait for notifications:
-   ```json
-   { "method": "account/login/completed", "params": { "loginId": "<uuid>", "success": true, "error": null } }
-   { "method": "account/updated", "params": { "authMode": "chatgpt" } }
-   ```
-
-### 4) Cancel a ChatGPT login
-
-```json
-{ "method": "account/login/cancel", "id": 4, "params": { "loginId": "<uuid>" } }
-{ "method": "account/login/completed", "params": { "loginId": "<uuid>", "success": false, "error": "…" } }
-```
-
-### 5) Logout
-
-```json
-{ "method": "account/logout", "id": 5 }
-{ "id": 5, "result": {} }
-{ "method": "account/updated", "params": { "authMode": null } }
-```
-
-### 6) Rate limits (ChatGPT)
-
-```json
-{ "method": "account/rateLimits/read", "id": 6 }
-{ "id": 6, "result": { "rateLimits": { "primary": { "usedPercent": 25, "windowDurationMins": 15, "resetsAt": 1730947200 }, "secondary": null } } }
-{ "method": "account/rateLimits/updated", "params": { "rateLimits": { … } } }
-```
-
-Field notes:
-- `usedPercent` is current usage within the OpenAI quota window.
-- `windowDurationMins` is the quota window length.
-- `resetsAt` is a Unix timestamp (seconds) for the next reset.
-
-### Dev notes
-
-- `codex app-server generate-ts --out <dir>` emits v2 types under `v2/`.
-- `codex app-server generate-json-schema --out <dir>` outputs `codex_app_server_protocol.schemas.json`.
-- See [“Authentication and authorization” in the config docs](../../docs/config.md#authentication-and-authorization) for configuration knobs.

-# Client Extraction Plan
-
-## Goals
-- Split the HTTP transport/client code out of `codex-core` into a reusable crate that is agnostic of Codex/OpenAI business logic and API schemas.
-- Create a separate API library crate that houses typed requests/responses for well-known APIs (Responses, Chat Completions, Compact) and plugs into the transport crate via minimal traits.
-- Preserve current behaviour (auth headers, retries, SSE handling, rate-limit parsing, compaction, fixtures) while making the APIs symmetric and avoiding code duplication.
-- Keep existing consumers (`codex-core`, tests, and tools) stable by providing a small compatibility layer during the transition.
-
-## Snapshot of Today
-- `core/src/client.rs (ModelClient)` owns config/auth/session state, chooses wire API, builds payloads, drives retries, parses SSE, compaction, and rate-limit headers.
-- `core/src/chat_completions.rs` implements the Chat Completions call + SSE parser + aggregation helper.
-- `core/src/client_common.rs` holds `Prompt`, tool specs, shared request structs (`ResponsesApiRequest`, `TextControls`), and `ResponseEvent`/`ResponseStream`.
-- `core/src/default_client.rs` wraps `reqwest` with Codex UA/originator defaults.
-- `core/src/model_provider_info.rs` models providers (base URL, headers, env keys, retry/timeout tuning) and builds `CodexRequestBuilder`s.
-    - Current retry logic is co-located with API handling; streaming SSE parsing is duplicated across Responses/Chat.
-
-## Target Crates (with interfaces)
-
-- `codex-client` (generic transport)
-  - Owns the generic HTTP machinery: a `CodexHttpClient`/`CodexRequestBuilder`-style wrapper, retry/backoff hooks, streaming connector (SSE framing + idle timeout), header injection, and optional telemetry callbacks.
-  - Does **not** know about OpenAI/Codex-specific paths, headers, or error codes; it only exposes HTTP-level concepts (status, headers, bodies, connection errors).
-  - Minimal surface:
-    ```rust
-    pub trait HttpTransport {
-        fn execute(&self, req: Request) -> Result<Response, TransportError>;
-        fn stream(&self, req: Request) -> Result<ByteStream, TransportError>;
-    }
-
-    pub struct Request {
-        pub method: Method,
-        pub url: String,
-        pub headers: HeaderMap,
-        pub body: Option<serde_json::Value>,
-        pub timeout: Option<Duration>,
-    }
-    ```
-  - Generic client traits (request/response/chunk are abstract over the transport):
-    ```rust
-    #[async_trait::async_trait]
-    pub trait UnaryClient<Req, Resp> {
-        async fn run(&self, req: Req) -> Result<Resp, TransportError>;
-    }
-
-    #[async_trait::async_trait]
-    pub trait StreamClient<Req, Chunk> {
-        async fn run(&self, req: Req) -> Result<ResponseStream<Chunk>, TransportError>;
-    }
-
-    pub struct RetryPolicy {
-        pub max_attempts: u64,
-        pub base_delay: Duration,
-        pub retry_on: RetryOn, // e.g., transport errors + 429/5xx
-    }
-    ```
-    - `RetryOn` lives in `codex-client` and captures HTTP status classes and transport failures that qualify for retry.
-    - Implementations in `codex-api` plug in their own request types, parsers, and retry policies while reusing the transport’s backoff and error types.
-    - Planned runtime helper:
-      ```rust
-      pub async fn run_with_retry<T, F, Fut>(
-          policy: RetryPolicy,
-          make_req: impl Fn() -> Request,
-          op: F,
-      ) -> Result<T, TransportError>
-      where
-          F: Fn(Request) -> Fut,
-          Fut: Future<Output = Result<T, TransportError>>,
-      {
-          for attempt in 0..=policy.max_attempts {
-              let req = make_req();
-              match op(req).await {
-                  Ok(resp) => return Ok(resp),
-                  Err(err) if policy.retry_on.should_retry(&err, attempt) => {
-                      tokio::time::sleep(backoff(policy.base_delay, attempt + 1)).await;
-                  }
-                  Err(err) => return Err(err),
-              }
-          }
-          Err(TransportError::RetryLimit)
-      }
-      ```
-      - Unary clients wrap `transport.execute` with this helper and then deserialize.
-      - Stream clients wrap the **initial** `transport.stream` call with this helper. Mid-stream disconnects are surfaced as `StreamError`s; automatic resume/reconnect can be added later on top of this primitive if we introduce cursor support.
-  - Common helpers: `retry::backoff(attempt)`, `errors::{TransportError, StreamError}`.
-  - Streaming utility (SSE framing only):
-    ```rust
-    pub fn sse_stream<S>(
-        bytes: S,
-        idle_timeout: Duration,
-        tx: mpsc::Sender<Result<String, StreamError>>,
-        telemetry: Option<Box<dyn Telemetry>>,
-    )
-    where
-        S: Stream<Item = Result<Bytes, TransportError>> + Unpin + Send + 'static;
-    ```
-    - `sse_stream` is responsible for timeouts, connection-level errors, and emitting raw `data:` chunks as UTF-8 strings; parsing those strings into structured events is done in `codex-api`.
-
-- `codex-api` (OpenAI/Codex API library)
-  - Owns typed models for Responses/Chat/Compact plus shared helpers (`Prompt`, tool specs, text controls, `ResponsesApiRequest`, etc.).
-  - Knows about OpenAI/Codex semantics:
-    - URL shapes (`/v1/responses`, `/v1/chat/completions`, `/responses/compact`).
-    - Provider configuration (`WireApi`, base URLs, query params, per-provider retry knobs).
-    - Rate-limit headers (`x-codex-*`) and their mapping into `RateLimitSnapshot` / `CreditsSnapshot`.
-    - Error body formats (`{ error: { type, code, message, plan_type, resets_at } }`) and how they become API errors (context window exceeded, quota/usage limit, etc.).
-    - SSE event names (`response.output_item.done`, `response.completed`, `response.failed`, etc.) and their mapping into high-level events.
-  - Provides a provider abstraction (conceptually similar to `ModelProviderInfo`):
-    ```rust
-    pub struct Provider {
-        pub name: String,
-        pub base_url: String,
-        pub wire: WireApi, // Responses | Chat
-        pub headers: HeaderMap,
-        pub retry: RetryConfig,
-        pub stream_idle_timeout: Duration,
-    }
-
-    pub trait AuthProvider {
-        /// Returns a bearer token to use for this request (if any).
-        /// Implementations are expected to be cheap and to surface already-refreshed tokens;
-        /// higher layers (`codex-core`) remain responsible for token refresh flows.
-        fn bearer_token(&self) -> Option<String>;
-
-        /// Optional ChatGPT account id header for Chat mode.
-        fn account_id(&self) -> Option<String>;
-    }
-    ```
-  - Ready-made clients built on `HttpTransport`:
-    ```rust
-    pub struct ResponsesClient<T: HttpTransport, A: AuthProvider> { /* ... */ }
-    impl<T, A> ResponsesClient<T, A> {
-        pub async fn stream(&self, prompt: &Prompt) -> ApiResult<ResponseStream<ApiEvent>>;
-        pub async fn compact(&self, prompt: &Prompt) -> ApiResult<Vec<ResponseItem>>;
-    }
-
-    pub struct ChatClient<T: HttpTransport, A: AuthProvider> { /* ... */ }
-    impl<T, A> ChatClient<T, A> {
-        pub async fn stream(&self, prompt: &Prompt) -> ApiResult<ResponseStream<ApiEvent>>;
-    }
-
-    pub struct CompactClient<T: HttpTransport, A: AuthProvider> { /* ... */ }
-    impl<T, A> CompactClient<T, A> {
-        pub async fn compact(&self, prompt: &Prompt) -> ApiResult<Vec<ResponseItem>>;
-    }
-    ```
-  - Streaming events unified across wire APIs (this can closely mirror `ResponseEvent` today, and we may type-alias one to the other during migration):
-    ```rust
-    pub enum ApiEvent {
-        Created,
-        OutputItemAdded(ResponseItem),
-        OutputItemDone(ResponseItem),
-        OutputTextDelta(String),
-        ReasoningContentDelta { delta: String, content_index: i64 },
-        ReasoningSummaryDelta { delta: String, summary_index: i64 },
-        RateLimits(RateLimitSnapshot),
-        Completed { response_id: String, token_usage: Option<TokenUsage> },
-    }
-    ```
-  - Error layering:
-    - `codex-client`: defines `TransportError` / `StreamError` (status codes, IO, timeouts).
-    - `codex-api`: defines `ApiError` that wraps `TransportError` plus API-specific errors parsed from bodies and headers.
-    - `codex-core`: maps `ApiError` into existing `CodexErr` variants so downstream callers remain unchanged.
-  - Aggregation strategies (today’s `AggregateStreamExt`) live here as adapters (`Aggregated`, `Streaming`) that transform `ResponseStream<ApiEvent>` into the higher-level views used by `codex-core`.
-
-## Implementation Steps
-
-1. **Create crates**: add `codex-client` and `codex-api` (names keep the `codex-` prefix). Stub lib files with feature flags/tests wired into the workspace; wire them into `Cargo.toml`.
-2. **Extract API-level SSE + rate limits into `codex-api`**:
-   - Move the Responses SSE parser (`process_sse`), rate-limit parsing, and related tests from `core/src/client.rs` into `codex-api`, keeping the behavior identical.
-   - Introduce `ApiEvent` (initially equivalent to `ResponseEvent`) and `ApiError`, and adjust the parser to emit those.
-   - Provide test-only helpers for fixture streams (replacement for `CODEX_RS_SSE_FIXTURE`) in `codex-api`.
-3. **Lift transport layer into `codex-client`**:
-   - Move `CodexHttpClient`/`CodexRequestBuilder`, UA/originator plumbing, and backoff helpers from `core/src/default_client.rs` into `codex-client` (or a thin wrapper on top of it).
-   - Introduce `HttpTransport`, `Request`, `RetryPolicy`, `RetryOn`, and `run_with_retry` as described above.
-   - Keep sandbox/no-proxy toggles behind injected configuration so `codex-client` stays generic and does not depend on Codex-specific env vars.
-4. **Model provider abstraction in `codex-api`**:
-   - Relocate `ModelProviderInfo` (base URL, env/header resolution, retry knobs, wire API enum) into `codex-api`, expressed in terms of `Provider` and `AuthProvider`.
-   - Ensure provider logic handles:
-     - URL building for Responses/Chat/Compact (including Azure special cases).
-     - Static and env-based headers.
-     - Per-provider retry and idle-timeout settings that map cleanly into `RetryPolicy`/`RetryOn`.
-5. **API crate wiring**:
-   - Move `Prompt`, tool specs, `ResponsesApiRequest`, `TextControls`, and `ResponseEvent/ResponseStream` into `codex-api` under modules (`common`, `responses`, `chat`, `compact`), keeping public types stable or re-exported through `codex-core` as needed.
-   - Rebuild Responses and Chat clients on top of `HttpTransport` + `StreamClient`, reusing shared retry + SSE helpers; keep aggregation adapters as reusable strategies instead of `ModelClient`-local logic.
-   - Implement Compact on top of `UnaryClient` and the unary `execute` path with JSON deserialization, sharing the same retry policy.
-   - Keep request builders symmetric: each client prepares a `Request<serde_json::Value>`, attaches headers/auth via `AuthProvider`, and plugs in its parser (streaming clients) or deserializer (unary) while sharing retry/backoff configuration derived from `Provider`.
-6. **Core integration layer**:
-   - Replace `core::ModelClient` internals with thin adapters that construct `codex-api` clients using `Config`, `AuthManager`, and `OtelEventManager`.
-   - Keep the public `ModelClient` API and `ResponseEvent`/`ResponseStream` types stable by re-exporting `codex-api` types or providing type aliases.
-   - Preserve existing auth flows (including ChatGPT token refresh) inside `codex-core` or a thin adapter, using `AuthProvider` to surface bearer tokens to `codex-api` and handling 401/refresh semantics at this layer.
-7. **Tests/migration**:
-   - Move unit tests for SSE parsing, retry/backoff decisions, and provider/header behavior into the new crates; keep integration tests in `core` using the compatibility layer.
-   - Update fixtures to be consumed via test-only adapters in `codex-api`.
-   - Run targeted `just fmt`, `just fix -p` for the touched crates, and scoped `cargo test -p codex-client`, `-p codex-api`, and existing `codex-core` suites.
-
-## Design Decisions
-
-- **UA construction**
-  - `codex-client` exposes an optional UA suffix/provider hook (tiny feature) and remains unaware of the CLI; `codex-core` / the CLI compute the full UA (including `terminal::user_agent()`) and pass the suffix or builder down.
-- **Config vs provider**
-  - Most configuration stays in `codex-core`. `codex-api::Provider` only contains what is strictly required for HTTP (base URLs, query params, retry/timeout knobs, wire API), while higher-level knobs (reasoning defaults, verbosity flags, etc.) remain core concerns.
-- **Auth flow ownership**
-  - Auth flows (including ChatGPT token refresh) remain in `codex-core`. `AuthProvider` simply exposes already-fresh tokens/account IDs; 401 handling and refresh retries stay in the existing auth layer.
-- **Error enums**
-  - `codex-client` continues to define `TransportError` / `StreamError`. `codex-api` defines an `ApiError` (deriving `thiserror::Error`) that wraps `TransportError` and API-specific failures, and `codex-core` maps `ApiError` into existing `CodexErr` variants for callers.
-- **Streaming reconnection semantics**
-  - For now, mid-stream SSE failures are surfaced as errors and only the initial connection is retried via `run_with_retry`. We will revisit mid-stream reconnect/resume once the underlying APIs support cursor/idempotent event semantics.

-# codex-api
-
-Typed clients for Codex/OpenAI APIs built on top of the generic transport in `codex-client`.
-
-- Hosts the request/response models and prompt helpers for Responses, Chat Completions, and Compact APIs.
-- Owns provider configuration (base URLs, headers, query params), auth header injection, retry tuning, and stream idle settings.
-- Parses SSE streams into `ResponseEvent`/`ResponseStream`, including rate-limit snapshots and API-specific error mapping.
-- Serves as the wire-level layer consumed by `codex-core`; higher layers handle auth refresh and business logic.
-
-## Core interface
-
-The public interface of this crate is intentionally small and uniform:
-
-- **Prompted endpoints (Chat + Responses)**
-  - Input: a single `Prompt` plus endpoint-specific options.
-    - `Prompt` (re-exported as `codex_api::Prompt`) carries:
-      - `instructions: String` – the fully-resolved system prompt for this turn.
-      - `input: Vec<ResponseItem>` – conversation history and user/tool messages.
-      - `tools: Vec<serde_json::Value>` – JSON tools compatible with the target API.
-      - `parallel_tool_calls: bool`.
-      - `output_schema: Option<Value>` – used to build `text.format` when present.
-  - Output: a `ResponseStream` of `ResponseEvent` (both re-exported from `common`).
-
-- **Compaction endpoint**
-  - Input: `CompactionInput<'a>` (re-exported as `codex_api::CompactionInput`):
-    - `model: &str`.
-    - `input: &[ResponseItem]` – history to compact.
-    - `instructions: &str` – fully-resolved compaction instructions.
-  - Output: `Vec<ResponseItem>`.
-  - `CompactClient::compact_input(&CompactionInput, extra_headers)` wraps the JSON encoding and retry/telemetry wiring.
-
-All HTTP details (URLs, headers, retry/backoff policies, SSE framing) are encapsulated in `codex-api` and `codex-client`. Callers construct prompts/inputs using protocol types and work with typed streams of `ResponseEvent` or compacted `ResponseItem` values.
