Timing and trigger usually separate sensory clues better than vivid descriptive labels alone.

Use the tool as a record, not a verdict

The output summarizes change and timing. It does not replace access to the building assembly or a professional inspection.

Keep the measurement point, instrument mode and observation language consistent so the next reading can be compared with the last.

A timeline is valuable because it shows what happened before and after weather, water use, heating cycles or repair work.
