Canonisation

Where two accepted claims disagree, no value wins by default. An Engineer Lead selects the canonical one and records why, and that selection is what every downstream check compares against.

Automatically resolved

3

Only where claims agreed exactly after normalisation and criticality was MEDIUM or below.

Silent automatic resolution is allowed in one narrow case: every claim normalises to the same value and the attribute is not HIGH or CRITICAL. Anything else waits for a named person, because a quiet tie-break on a critical rating is indistinguishable from a guess.
Rated current of the main busbar (InA)
2 accepted claims disagree. No canonical value exists, so nothing downstream can be checked against this attribute.
Critical
Source authority: Customer specification outranks Manufacturer data for Rated current of the main busbar (InA), so 4000 A is recommended over 3200 A. This is a recommendation: an Engineer Lead selects, and may overrule it with a recorded reason.

Cable entry direction
