One base size could not answer the full range.

The starting point

The base size was approved while endpoint sizes and proportional details remained unseen.

The development decisions

1. 01

   Choose sizes that reveal grade transitions.

2. 02

   Track coverage and seam position, not measurements alone.

3. 03

   Document any size-specific construction.

What would close the scenario

Size-set review map with separate fit and measurement decisions.

This approval route is illustrative. A live project must define the responsible people, sample identity, evidence scope and accepted revision.
