Observation is not cause
A crack, darker area, loose finish or growth can have many possible explanations. The app does not classify severity or prescribe treatment.
Stratum 04 · Surface Signals
Describe change without diagnosing it
Eight signal lenses cover fine cracking, local erosion, discoloration, finish separation, impact, opening movement, visible growth and post-event change.
The app keeps each idea bounded: observe without touching, ask without diagnosing, check the current source, adapt the conversation and stop when authority or safety must take over.
Context is part of the note
Location, extent, nearby junctions, recent events and change over time are useful questions for a qualified conversation.
Post-event stop
After earthquake, storm, flood, impact or fire, do not enter or compare an image to judge safety. Follow official and site-controller directions.
Health and services boundary
Strong odour, extensive growth, heat, sparking, active water or damaged services requires appropriate professional or emergency action.

Keep the real decision with the real authority
Use a current authorised source and the qualified person responsible for the actual project. This website is a support package for the app, not a project record or approval.
