 - **Static Typing:** Enforce explicit type hints for all signatures and variables.
 - **Decoupling:** Follow "call down, signal up".
 - **Validation:** Resolve the Godot 4.7.1 binary for the current platform using `AGENTS.md`. Run syntax/import checks, relevant existing suites, and focused automated tests of the feature's observable outcomes. For runtime interactions, exercise a minimal scene or fixture through the real production path, advance frames or physics ticks, and assert the result. Fix failures and rerun the affected checks. Inspect rendered output when available; state clearly when visual behavior could not be checked.
+- **Windows visual verification:** The Windows screenshot service repeatedly times out on Project Manager/Godot windows. Do not retry it; use a focused Godot GUI run or harness that saves a viewport PNG, inspect the saved image locally, and assert the relevant interactions in the same focused verification workflow.

+## Windows UI visual checks
+
+The Windows screenshot service repeatedly times out when capturing Project Manager/Godot windows. Do not rely on or retry its live-window feed. When a visual implementation check is needed, direct the developer to run a focused Godot scene or harness that saves a viewport PNG and inspect that local image; pair it with interaction checks for the relevant controls.

 ## Worktree choice
 
 You are read-only and must not create worktrees or write project files. For any handoff that will create project files, confirm that the orchestrator has asked the user whether to use a worktree and supplied the selected project path and branch. Do not require a worktree when the user chooses the current checkout.
