- `apps/web`: React/Vite UI. Owns session UX, conversation/event rendering, and client-side state. Connects to the server via WebSocket.
- `packages/contracts`: Shared Zod schemas and TypeScript contracts for provider events, WebSocket protocol, and model/session types.

## Provider WS API Docs Sync (Required)
- The canonical provider API spec lives at `docs/provider-ws-api.md`.
- Any change to provider WS contracts, methods/channels, canonical event shapes, normalization mappings, replay/backpressure behavior, or client apply semantics must update `docs/provider-ws-api.md` in the same PR.
- If code and docs diverge, treat it as a bug and resolve before merge.

## Codex App Server (Important)
T3 Code is currently Codex-first. The server starts `codex app-server` (JSON-RPC over stdio) per provider session, then streams structured events to the browser through WebSocket push messages.

How we use it in this codebase:
- Session startup/resume and turn lifecycle are brokered in `apps/server/src/codexAppServerManager.ts`.
- Provider dispatch and thread event logging are coordinated in `apps/server/src/providerManager.ts`.
- WebSocket server routes NativeApi methods in `apps/server/src/wsServer.ts`.
- Web app consumes provider event streams via WebSocket push on channel `providers.event`.
- Web app consumes canonical provider stream frames via WebSocket push on channel `providers.stream`.

## Provider architecture

The web app communicates with the server via WebSocket using a simple JSON-RPC-style protocol:
The web app communicates with the server via WebSocket using a JSON-RPC-style request/response layer plus a single canonical provider stream:

- **Request/Response**: `{ id, method, params }` → `{ id, result }` or `{ id, error }`
- **Push events**: `{ type: "push", channel, data }` for streaming provider events
- **Push stream**: `{ type: "push", channel: "providers.stream", data: ProviderStreamFrame }`

Methods mirror the `NativeApi` interface defined in `@t3tools/contracts`:

- `providers.startSession`, `providers.sendTurn`, `providers.interruptTurn`
- `providers.respondToRequest`, `providers.stopSession`, `providers.listSessions`
- `providers.respondToApproval`, `providers.stopSession`, `providers.listSessions`
- `providers.openStream`, `providers.closeStream`
- `shell.openInEditor`, `server.getConfig`

Codex is the only implemented provider. `claudeCode` is reserved in contracts/UI.
The stream contract is `snapshot + delta` with cursor replay (`afterSeq`) for reconnect safety. The server normalizes provider-native events (currently Codex raw app-server events) into canonical events so UI rendering stays provider-agnostic.

See `docs/provider-ws-api.md` for the full canonical schema, event mapping, and replay/gap semantics.

- `packages/contracts`: Shared Zod schemas and TypeScript contracts for provider events, WebSocket protocol, and model/session types.

## Provider WS API Docs Sync (Required)
- The canonical provider API spec lives at `docs/provider-ws-api.md`.
- Any change to provider WS contracts, methods/channels, canonical event shapes, normalization mappings, replay/backpressure behavior, or client apply semantics must update `docs/provider-ws-api.md` in the same PR.
- If code and docs diverge, treat it as a bug and resolve before merge.

## Codex App Server (Important)
T3 Code is currently Codex-first. The server starts `codex app-server` (JSON-RPC over stdio) per provider session, then streams structured events to the browser through WebSocket push messages.

How we use it in this codebase:
- Session startup/resume and turn lifecycle are brokered in `apps/server/src/codexAppServerManager.ts`.
- Provider dispatch and thread event logging are coordinated in `apps/server/src/providerManager.ts`.
- WebSocket server routes NativeApi methods in `apps/server/src/wsServer.ts`.
- Web app consumes provider event streams via WebSocket push on channel `providers.event`.
- Web app consumes canonical provider stream frames via WebSocket push on channel `providers.stream`.

## Provider architecture

The web app communicates with the server via WebSocket using a simple JSON-RPC-style protocol:
The web app communicates with the server via WebSocket using a JSON-RPC-style request/response layer plus a single canonical provider stream:

- **Request/Response**: `{ id, method, params }` → `{ id, result }` or `{ id, error }`
- **Push events**: `{ type: "push", channel, data }` for streaming provider events
- **Push stream**: `{ type: "push", channel: "providers.stream", data: ProviderStreamFrame }`

Methods mirror the `NativeApi` interface defined in `@t3tools/contracts`:

- `providers.startSession`, `providers.sendTurn`, `providers.interruptTurn`
- `providers.respondToRequest`, `providers.stopSession`, `providers.listSessions`
- `providers.respondToApproval`, `providers.stopSession`, `providers.listSessions`
- `providers.openStream`, `providers.closeStream`
- `shell.openInEditor`, `server.getConfig`

Codex is the only implemented provider. `claudeCode` is reserved in contracts/UI.
The stream contract is `snapshot + delta` with cursor replay (`afterSeq`) for reconnect safety. The server normalizes provider-native events (currently Codex raw app-server events) into canonical events so UI rendering stays provider-agnostic.

See `docs/provider-ws-api.md` for the full canonical schema, event mapping, and replay/gap semantics.

- `packages/contracts`: Shared Zod schemas and TypeScript contracts for provider events, WebSocket protocol, and model/session types.

## Provider WS API Docs Sync (Required)
- The canonical provider API spec lives at `docs/provider-ws-api.md`.
- Any change to provider WS contracts, methods/channels, canonical event shapes, normalization mappings, replay/backpressure behavior, or client apply semantics must update `docs/provider-ws-api.md` in the same PR.
- If code and docs diverge, treat it as a bug and resolve before merge.

## Codex App Server (Important)
T3 Code is currently Codex-first. The server starts `codex app-server` (JSON-RPC over stdio) per provider session, then streams structured events to the browser through WebSocket push messages.

How we use it in this codebase:
- Session startup/resume and turn lifecycle are brokered in `apps/server/src/codexAppServerManager.ts`.
- Provider dispatch and thread event logging are coordinated in `apps/server/src/providerManager.ts`.
- WebSocket server routes NativeApi methods in `apps/server/src/wsServer.ts`.
- Web app consumes provider event streams via WebSocket push on channel `providers.event`.
- Web app consumes canonical provider stream frames via WebSocket push on channel `providers.stream`.

## Provider architecture

The web app communicates with the server via WebSocket using a simple JSON-RPC-style protocol:
The web app communicates with the server via WebSocket using a JSON-RPC-style request/response layer plus a single canonical provider stream:

- **Request/Response**: `{ id, method, params }` → `{ id, result }` or `{ id, error }`
- **Push events**: `{ type: "push", channel, data }` for streaming provider events
- **Push stream**: `{ type: "push", channel: "providers.stream", data: ProviderStreamFrame }`

Methods mirror the `NativeApi` interface defined in `@t3tools/contracts`:

- `providers.startSession`, `providers.sendTurn`, `providers.interruptTurn`
- `providers.respondToRequest`, `providers.stopSession`, `providers.listSessions`
- `providers.respondToApproval`, `providers.stopSession`, `providers.listSessions`
- `providers.openStream`, `providers.closeStream`
- `shell.openInEditor`, `server.getConfig`

Codex is the only implemented provider. `claudeCode` is reserved in contracts/UI.
The stream contract is `snapshot + delta` with cursor replay (`afterSeq`) for reconnect safety. The server normalizes provider-native events (currently Codex raw app-server events) into canonical events so UI rendering stays provider-agnostic.

See `docs/provider-ws-api.md` for the full canonical schema, event mapping, and replay/gap semantics.

- `apps/web`: React/Vite UI. Owns session UX, conversation/event rendering, and client-side state. Connects to the server via WebSocket.
- `packages/contracts`: Shared Zod schemas and TypeScript contracts for provider events, WebSocket protocol, and model/session types.

## Provider WS API Docs Sync (Required)
- The canonical provider API spec lives at `docs/provider-ws-api.md`.
- Any change to provider WS contracts, methods/channels, canonical event shapes, normalization mappings, replay/backpressure behavior, or client apply semantics must update `docs/provider-ws-api.md` in the same PR.
- If code and docs diverge, treat it as a bug and resolve before merge.

## Codex App Server (Important)
T3 Code is currently Codex-first. The server starts `codex app-server` (JSON-RPC over stdio) per provider session, then streams structured events to the browser through WebSocket push messages.

How we use it in this codebase:
- Session startup/resume and turn lifecycle are brokered in `apps/server/src/codexAppServerManager.ts`.
- Provider dispatch and thread event logging are coordinated in `apps/server/src/providerManager.ts`.
- WebSocket server routes NativeApi methods in `apps/server/src/wsServer.ts`.
- Web app consumes provider event streams via WebSocket push on channel `providers.event`.
- Web app consumes canonical provider stream frames via WebSocket push on channel `providers.stream`.

## Provider architecture

The web app communicates with the server via WebSocket using a simple JSON-RPC-style protocol:
The web app communicates with the server via WebSocket using a JSON-RPC-style request/response layer plus a single canonical provider stream:

- **Request/Response**: `{ id, method, params }` → `{ id, result }` or `{ id, error }`
- **Push events**: `{ type: "push", channel, data }` for streaming provider events
- **Push stream**: `{ type: "push", channel: "providers.stream", data: ProviderStreamFrame }`

Methods mirror the `NativeApi` interface defined in `@t3tools/contracts`:

- `providers.startSession`, `providers.sendTurn`, `providers.interruptTurn`
- `providers.respondToRequest`, `providers.stopSession`, `providers.listSessions`
- `providers.respondToApproval`, `providers.stopSession`, `providers.listSessions`
- `providers.openStream`, `providers.closeStream`
- `shell.openInEditor`, `server.getConfig`

Codex is the only implemented provider. `claudeCode` is reserved in contracts/UI.
The stream contract is `snapshot + delta` with cursor replay (`afterSeq`) for reconnect safety. The server normalizes provider-native events (currently Codex raw app-server events) into canonical events so UI rendering stays provider-agnostic.

See `docs/provider-ws-api.md` for the full canonical schema, event mapping, and replay/gap semantics.
