The evidence matters

A clear view.
An informed decision.

The original record, always.

Every CEC record leads back to its source workbook and check date. Archived files preserve the evidence even when a live list changes.

Follow the evidence

Context before conclusions.

A listing is one part of the picture. Model variants, utility requirements and installation conditions deserve the same attention.
