    1. Capture the exact failure state

      Reversible

      Record the exact setting, profile or version active in the application producing the wrong result. Expected behavior: return current files and apps after indexing completes.

    2. Isolate the component boundary

      Reversible

      Search a known local file, inspect Privacy exclusions and allow indexing on power. Reproduce the same input in a different application or user profile to see whether the fault follows the app or the system. Boundary to separate: indexing progress versus excluded locations, external drives and filesystem health.

    3. Correct only the proven cause

      Reversible

      Remove an accidental exclusion or rebuild only the affected volume index. Correct the setting, color/display profile or driver version proven by the comparison.

    4. Verify and stop safely

      Reversible

      Repeat the original task and confirm the correct output with the fix applied. Back up and stop for storage errors or missing files outside search.
