Engineering index

Connector contact-count index

Browse only engineering profiles whose source-checked sidecar publishes a positive contact or position count. Count is an identifier, not a wiring map or compatibility result.

Classification is not compatibility.

These tables reorganize facts already present in the canonical field notes and engineering sidecars. A shared count, role word, coupling method, alias or family label does not prove that two parts mate, carry the same signal, use the same wiring or are safe substitutes.
