## What changed
Define `thread/prediction/request` with `threadId` and `sourceTurnId`, and `thread/prediction/updated` with a `completed` result containing optional text or a `failed` result.
Update generated JSON schemas, TypeScript types, and Python notification models. Route prediction notifications to their thread in the TUI and ignore them in the chat widget.
The request remains unimplemented and returns a method-not-found error.

## Why
Clients with a gateway sign-in UI need to control when browser authorization starts and inspect credential readiness before making authenticated requests.
## What changed
- Add `initialize.capabilities.explicitGatewayOauth` to require explicit login while allowing existing credentials to refresh. Preserve automatic authorization for clients that omit the capability, and prevent later connections from undoing explicit opt-in.
- Add `account/gatewayOAuth/read`, `account/gatewayOAuth/login`, and `account/gatewayOAuth/cancel`, plus `account/gatewayOAuth/changed` notifications. Send the authorization URL only to the initiating connection and cancel its login on disconnect.
- Check gateway authentication before returning cached results from `model/list`, with restart guidance when provider settings have changed.
- Update protocol schemas, TypeScript and Python bindings, and document capability probing and the sign-in lifecycle.
## Testing
Add tests for passive readiness reads, credential reuse after login, token exchange failures, cancellation and immediate retry, connection ownership, legacy versus explicit login, and model-list authentication checks.

## What changed
- Add `thread/attachment/add`, `thread/attachment/list`, and `thread/attachment/remove` to manage durable resource references without loading the owning thread or changing conversation history.
- Identify attachments by thread, `attachmentType`, and `identityKey`. Repeated adds return the existing attachment; repeated removals succeed without emitting another update. Listing supports cursor pagination.
- Broadcast `thread/attachment/updated` after creation or deletion, after responding to the requester. Serialize attachment mutations with thread lifecycle operations and reject stores that do not support attachments.
- Update protocol schemas, TypeScript and Python bindings, documentation, and TUI notification handling so attachment updates do not add untracked threads to the agent picker.
## Testing
Add coverage for unloaded threads, pagination, idempotent addition and removal, reattachment, invalid inputs, unsupported stores, response-before-notification ordering across clients, and TUI notification routing.

## Why
Keep Python protocol models aligned with the checked-in app-server schemas and preserve reviewed generated artifacts when staging SDK releases.
## What changed
- Generate SDK types from the schema directory configured in `pyproject.toml`, with a `--schema-dir` override, instead of invoking the pinned runtime binary.
- Refresh Python artifacts through `just write-app-server-schema` for standard repository exports. Skip SDK updates for scratch and experimental exports.
- Regenerate protocol models and notification dispatch, deriving the known payload union from the registry so `Notification.payload` covers every registered event.
- Explicitly allowlist convenience API parameters so new protocol fields do not silently expand method signatures. Preserve existing approval path wrappers.
- Stage SDK releases using checked-in generated files without regenerating them.
## Testing
Add coverage for schema selection, refresh gating and failure handling, release artifact preservation, notification payload typing, and approval path compatibility. Update the generation drift test to use repository schemas.

## What changed
- Pin `openai-codex` to the `0.147.0` CLI runtime and regenerate its protocol models and lockfile.
- Allow stable Python SDK release tags and require their versions to match the pinned runtime.
- Expose the regenerated API additions, including thread sections, environment connection notifications, audio inputs, and the `section_id` thread-list filter.
## Testing
- Update release staging, generated-contract, notification, and public-signature coverage for the new runtime.
GitOrigin-RevId: 8b99ef6781e01c34d9d697c8c44247fb4e4fe3ab
## What changed
- Mark `openai-codex` as stable and align its versioned runtime dependency with Codex CLI `0.144.4`.
- Regenerate the Python protocol models and notification registry from that runtime, exposing the latest requests, responses, notifications, and schema fields.
- Keep `ReasoningEffort` and `ThreadSource` as enum-style APIs while accepting unknown future wire values, and omit `last_turn_id` from the flat `thread_fork` helper.
## Testing
- Cover stable SDK/runtime version matching, forward-compatible enum parsing, and generated client method signatures.

## Summary
- pin the Python SDK runtime package to `openai-codex-cli-bin==0.136.0`
so Ubuntu/glibc installs resolve a compatible wheel
- refresh generated SDK artifacts and lock data for the runtime update
- keep newly generated client-message-id wire models internal to the
generated protocol layer
## Dependency
- merge #25906 first so the Python SDK release publishes both manylinux
and musllinux runtime wheels before publishing the package with this pin
## Validation
- ran `just fmt`
- regenerated the Python public API helpers
- validated the edited workflow YAML
- CI passed 29/29 checks
## Why
The SDK should publish under the reserved public distribution name
`openai-codex`, and its import module should match that name in the
Python style. Since package names can contain hyphens but import modules
cannot, the public import path becomes `openai_codex`.
Keeping the rename separate from the public API surface change makes the
naming change easy to review and avoids mixing it with API curation.
## What
- Rename the SDK distribution from `openai-codex-app-server-sdk` to
`openai-codex`.
- Rename the import package from `codex_app_server` to `openai_codex`.
- Keep the runtime wheel as the separate `openai-codex-cli-bin`
dependency.
- Update docs, examples, notebooks, artifact scripts, lockfile metadata,
and tests for the new distribution/module names.
