Open engineering items
Every abstention, conflict, drift detection and check failure lands here. Nothing is dropped on the floor, and a gate consults this register directly.

OPN-2026-0045-0001HighConfiguration driftblocks G4open
MSB-01 configuration changed after approval
The upstream configuration CONF-88231 moved from revision 2 to revision 3 after it was approved. Cable entry changed from bottom to top and the busbar rating dropped from 4000 A to 3200 A. The stored snapshot still holds revision 2.

OPN-2026-0045-0002CriticalRequirement conflictblocks G1open
Main busbar rating stated as both 4000 A and 3200 A
Specification clause 3.2 requires not less than 4000 A. Annex B data sheet states 3200 A. Both claims were accepted by different engineers, so no canonical value exists.

Internal arc classification not stated
Clause 3.7 requires adequate personnel protection but leaves the classification and accessibility type to be agreed. Extraction returned CLARIFICATION REQUIRED rather than guessing IAC A FLR.

OPN-2026-0045-0004HighDeviationopen
Design ambient of 65 C exceeds the plausibility envelope
Clause 3.6 states 65 C. The ontology envelope for ambient temperature is 20 C to 60 C. The value was not corrected; it was flagged MANUAL CHECK REQUIRED and needs a derating study or a written Employer confirmation.
Raised 2026-05-07 07:00 by normalisation, against attribute AmbientTemperatureMax

Site elevation not stated
Clause 3.6 defers site elevation to the Employer. Above 2000 m the insulation coordination is derated, so the value cannot be assumed.

OPN-2026-0045-0006MediumMissing evidenceopen
Peak withstand current proposed without a source
A value of 143 kA was proposed for the rated peak withstand but no anchor could be resolved in either source document. Recorded as EVIDENCE NOT FOUND and not acceptable.

Single line diagram shows 50 kA on the incomer
The requirement to SLD checker found MSB-01-Q1 carrying a short time withstand of 50 kA against a canonical value of 65 kA.

Modbus register map not yet agreed
Clause 3.5 defers the register map to detail design. Tracked so it is not forgotten before the communication FAT.
