VERIFICATION / PRE-COMPLIANCE
Compliance should confirm the design—not discover it for the first time.
Translate standards into ports, phenomena, operating modes, and performance criteria while accumulating comparative evidence during design.

Where can an external continuous field enter the system?

Which path carries a high-energy pulse to a sensitive node?

What constitutes a failure, and how is repeatability proven?
Operating modes · performance criteria · calibration · report01 / TEST MATRIX BUILDER
Derive verification phenomena from the product and its ports.
A standards navigator is more than a code list. Understand how the product connects to the outside world to avoid missing ports and worst-case modes.
SCOPE → PORT → PHENOMENA
Build the test matrix before selecting a standards code.
This is an engineering-planning model; formal applicability still requires the product-specific standard and target-market review.

02 / EVIDENCE THROUGH DEVELOPMENT
Every measurement enters the same evidence chain.
Pre-compliance enables rapid comparison; formal testing determines conformity. Both must share configuration, operating mode, and change records.
