Assumptions
•
Every implant is coated in protein before any cell arrives; cells meet that protein layer, not the material.
•
The times are rough and overlap, to show the scale: each stage starts before the last one ends.
•
A biocompatible material still draws this response; it should end in a thin capsule, not lasting inflammation.
