Use before touching decay half-life, prior/global-prior calculation, sensor-health repairs, sleep-presence detection, recorder/DB write volume, adjacent-areas, timezone/DST-sensitive datetime code, or the config-flow advanced-options gating — to check whether the bug you're about to fix (or the fix you're about to write) already happened before. Load this when a symptom rhymes with "custom value silently reverted to a default", "repairs fire spuriously / return after Ignore", "prior pinned near 0.99 or 0.01", "TypeError offset-naive and offset-aware", or "recorder database growing too fast".
