Summary

features/environment.py contains # type: ignore comments in the _install_fast_sleep_patch() function, violating the project's strict no-# type: ignore policy documented in CONTRIBUTING.md. The project requires full static typing with Pyright strict mode and explicitly prohibits # type: ignore suppressions.

Current State

In features/environment.py, the _install_fast_sleep_patch() function (which caps time.sleep and asyncio.sleep at 10ms for test performance) contains the following type suppressions:

def _install_fast_sleep_patch() -> None:
    import asyncio
    import time

    _MAX_SLEEP = 0.01  # 10 ms cap

    # --- synchronous time.sleep ---
    if not callable(getattr(time, "_original_sleep", None)):
        time._original_sleep = time.sleep  # type: ignore[attr-defined]

        def _capped_sleep(seconds: float) -> None:
            time._original_sleep(min(seconds, _MAX_SLEEP))  # type: ignore[attr-defined]

        time.sleep = _capped_sleep  # type: ignore[assignment]

    # --- asynchronous asyncio.sleep ---
    if not callable(getattr(asyncio, "_original_sleep", None)):
        asyncio._original_sleep = asyncio.sleep  # type: ignore[attr-defined]

        async def _capped_async_sleep(seconds: float, result: object = None) -> object:
            return await asyncio._original_sleep(min(seconds, _MAX_SLEEP), result)  # type: ignore[attr-defined]

        asyncio.sleep = _capped_async_sleep  # type: ignore[assignment]

This uses # type: ignore[attr-defined] (5 occurrences) and # type: ignore[assignment] (2 occurrences) to suppress Pyright errors when dynamically adding _original_sleep attributes to the time and asyncio modules and replacing their sleep functions.

Proposed Improvement

Replace the # type: ignore suppressions with proper type-safe alternatives:

Use cast() or Protocol to express the monkey-patching intent without suppressing type errors
Use setattr() with typed wrappers instead of direct attribute assignment on module objects
Define a _SleepModule Protocol that includes _original_sleep as an optional attribute
Use types.ModuleType subclass or a typed wrapper object to hold the patched state

Example approach:

from typing import cast, Any
import types

# Store originals in a typed dict instead of on the module
_sleep_originals: dict[str, Any] = {}

def _install_fast_sleep_patch() -> None:
    import asyncio
    import time

    _MAX_SLEEP = 0.01

    if "time_sleep" not in _sleep_originals:
        _sleep_originals["time_sleep"] = time.sleep
        def _capped_sleep(seconds: float) -> None:
            _sleep_originals["time_sleep"](min(seconds, _MAX_SLEEP))
        time.sleep = _capped_sleep  # Still needs cast but avoids attr-defined errors

Alternatively, use unittest.mock.patch or a context-manager approach that is already type-safe.

Expected Impact

Brings features/environment.py into compliance with CONTRIBUTING.md's strict typing policy
Allows Pyright to fully type-check the test infrastructure code
Removes 7 # type: ignore suppressions from the codebase
Improves maintainability by making the monkey-patching intent explicit in the type system

🔍 Triage Decision — Verified ✅

Decision: Verified | MoSCoW: Could Have | Priority: Low

This is a valid compliance issue. The _install_fast_sleep_patch() function in features/environment.py contains 7 # type: ignore suppressions, which violates the project's strict no-# type: ignore policy in CONTRIBUTING.md. While the monkey-patching of time.sleep and asyncio.sleep is inherently awkward to type, proper alternatives exist (using setattr() with typed wrappers, a typed dict for originals, or unittest.mock.patch).

Rationale:

The violation is real and well-documented
Impact is limited to test infrastructure code (not production paths)
7 suppressions is a meaningful but not critical compliance gap
Classified as Could Have: important for long-term type safety but not blocking
Assigned to v3.5.0 as a low-priority compliance cleanup

Next steps: Refactor _install_fast_sleep_patch() to store originals in a typed dict and use setattr() for module patching, eliminating all # type: ignore suppressions. Alternatively, migrate to unittest.mock.patch which is already type-safe.

✅ Verified — Could-Have | v3.6.0

This is a valid code quality issue. The # type: ignore suppressions in _install_fast_sleep_patch() violate the project's strict no-# type: ignore policy.

MoSCoW: Could-Have — This is a code quality improvement that doesn't affect functionality. The monkey-patching of time.sleep and asyncio.sleep is inherently difficult to type-check without suppressions, and the fix requires careful design. Low priority.

Milestone: v3.6.0 — Assigned to the Advanced Concepts milestone where code quality improvements are appropriate.

Implementation Attempt — Tier 1: haiku — Success

Implemented the type-safe refactoring of _install_fast_sleep_patch() in features/environment.py.

What was done:

Removed 6 # type: ignore suppressions (4 attr-defined + 2 assignment) from _install_fast_sleep_patch()
Used cast(Any, module) + direct attribute assignment as the type-safe alternative (avoids both # type: ignore and ruff B010 which disallows setattr() with constant strings)
Stored original sleep functions in typed local variables (_orig_time_sleep: Callable[[float], None]) so inner closures call them directly
Added from collections.abc import Callable and from typing import cast imports
Added features/test_infra_sleep_patch.feature with 4 BDD scenarios verifying behavior preservation
Added features/steps/test_infra_sleep_patch_steps.py with step definitions

Quality gate status: lint ✓, typecheck ✓, unit_tests ✓ (4/4 scenarios pass)
