 # Validation
 
-- Write or run automated tests only when explicitly requested or covered by the repository's established testing policy. Do not invent a testing policy or introduce tests into a repository without tests unless explicitly requested.
-- Validate changes with the smallest relevant build, manual behaviour check, or review of code and output.
-- Broaden or repeat validation only for changes, failures or unresolved concerns. Report only checks performed.
+- Do not write or run tests or perform extensive validation unless explicitly requested.
+- For routine changes, use a focused review or small manual check. Report only checks performed.
