runtime.py DOX

Purpose

• Own the runtime.py helper module.
• This module owns runtime identity, environment flags, and startup arguments.
• Keep this file-level DOX profile synchronized with runtime.py because this directory is intentionally flat.

Ownership

• runtime.py owns the runtime implementation.
• runtime.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Top-level functions:
• initialize()
• get_arg(name: str)
• has_arg(name: str)
• is_dockerized() -> bool
• is_development() -> bool
• get_local_url()
• get_runtime_id() -> str
• get_persistent_id() -> str
• async call_development_function(func: Callable[..., Awaitable[T]], *args, **kwargs) -> T
• async call_development_function(func: Callable[..., T], *args, **kwargs) -> T
• async call_development_function(func: Union[Callable[..., T], Callable[..., Awaitable[T]]], *args, **kwargs) -> T
• async handle_rfc(rfc_call: rfc.RFCCall)
• _get_rfc_password() -> str
• _get_rfc_url() -> str
• call_development_function_sync(func: Union[Callable[..., T], Callable[..., Awaitable[T]]], *args, **kwargs) -> T
• get_web_ui_port()
• get_tunnel_api_port()
• get_platform()
• is_windows()
• get_terminal_executable()
• Notable constants/configuration names: T, R.

Runtime Contracts

• Helper modules own reusable framework APIs and must preserve public callers unless all callers, tests, and docs are updated together.
• Update this file whenever public functions, classes, persistence behavior, path/security assumptions, side effects, or cross-module contracts change.
• Observed side-effect areas: filesystem reads, filesystem writes, subprocess/runtime control, settings/state persistence, secret handling, tunnel state.
• Imported dependency areas include: argparse, asyncio, helpers, inspect, nest_asyncio, pathlib, queue, secrets, sys, threading, typing.

Key Concepts

• Important called helpers/classes observed in the source: nest_asyncio.apply, TypeVar, argparse.ArgumentParser, parser.add_argument, parser.parse_known_args, vars, is_dockerized, dotenv.get_dotenv_value, is_development, settings.get_settings, url.endswith, queue.Queue, threading.Thread, thread.start, thread.join, thread.is_alive, result_queue.get_nowait, cast, is_windows, get_arg.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve public helper APIs used by core code and plugins unless every caller is updated.
• Keep path, auth, secret, persistence, network, and subprocess behavior explicit and bounded.
• Prefer adding cohesive helper functions here only when behavior is reused across modules.

Verification

• Run targeted tests for changed helper behavior; run security regressions for auth, filesystem, WebSocket, tunnel, upload, or secret-handling helpers.
• Related tests observed by source search:
  • tests/test_a0_connector_computer_use_metadata.py
  • tests/test_a0_connector_prompt_gating.py
  • tests/test_browser_agent_regressions.py
  • tests/test_default_prompt_budget.py
  • tests/test_document_query_plugin.py
  • tests/test_host_browser_connector.py
  • tests/test_http_auth_csrf.py
  • tests/test_image_get_security.py
