Four layers, one connected story.
The underside of the flooring gained moisture first
The moisture gradient caused the board edges to rise.
↓Visible distortion appeared after repeated cycles
The symptom lagged behind the source.
↓Cycle correlation and targeted access found the connection
After repair, the drying trend was tracked before finish decisions.
Canonical connection
The symptom and cause are separate objects.
The autopsy preserves how evidence connected them without collapsing uncertainty into one magic answer.
A dishwasher connection wetted the underside of wood flooring before the upper surface showed deformation.
The visible symptom was the final chapter
The investigation followed the source, transport path, affected material and verification step separately.
What changed the direction
Timing and location evidence ruled out attractive but weaker explanations before repair work began.
The durable lesson
Repair the controlling source and then verify the outcome under the conditions that previously triggered the symptom.
