Order-linked evidence
What happened after installation.
Design, production and maker reputation remain separate so the cause of a poor outcome is not obscured.
“Clear instructions and the pivot feels substantially firmer than the broken original.”
“Needed one light pass with a file on the stop. I added a dimensioned photo for other early units.”
Immutable release history
Geometry stays traceable.
Released production files are never silently overwritten. Material changes create a new version and new evidence context.
