Scope and common interpretation errors
For removable-window housings, not a complete optical- or structural-adhesive process design.
Water may enter at one edge and collect elsewhere; fixing holes can bypass the frame. Final droplet location can be mistaken for the inlet.

Turn the review into recorded checks
| Step | Action and evidence |
|---|---|
| 1 · Map connections | Identify lens, seal frame, fixing holes and drainage relationships. |
| 2 · Observe separate zones | Under identical assembly conditions, distinguish edges, holes and frame corners rather than blocking everything at once. |
| 3 · Retain reproducible evidence | Record entry time, orientation and photographs before opening. Retest the original conditions after correction. |
A comparison to avoid misinterpretation
If blocking fixing holes removes water traces, investigate that path further; this alone neither qualifies the frame nor eliminates durability testing.

Frequently asked question
Will a wider seal frame stop every bypass leak?
No. Interfaces bypassing the contact band need separate treatment.
