Engineering cognition
An answer in the fixed shape of the cognitive response contract: fourteen named sections, evidence instead of hidden reasoning, and an abstention token wherever a section has nothing to say.
Master prompt sections 24 and 92
TASK
- Establish the controlled value of Rated operational voltage (Ue) for this project and cite the evidence chain behind it.
CANONICAL FACTS
RELEVANT ENGINEERING OBJECTS
- MSB-01-Q1 Incoming air circuit breaker carries RatedVoltage = 400 (L3).
- MSB-01-BB1 Main horizontal busbar carries RatedVoltage = 400 (L3).
APPLICABLE REQUIREMENTS
APPLICABLE RULES
- IEC 61439-1 clause 5.2.1 governs Rated operational voltage (Ue). Line-to-line operational voltage of the main busbar system. Drives clearance, creepage and device selection.
SOURCE EVIDENCE
CALCULATIONS
- No validated calculation engine exists in the sandbox. Section 45 requires one for sizing, withstand and coordination, so any quantitative conclusion here rests on recorded values, not on a computed result.
CHECKER FINDINGS
CONCLUSION / RECOMMENDATION
- No canonical value and no accepted claim exists for Rated operational voltage (Ue). Nothing downstream can be checked against this attribute.
CONFIDENCE
NONE. No record of any trust state was used, so there is nothing to be confident about.
UNCERTAINTIES
- UNKNOWN: No claim of any kind exists for this attribute.
HUMAN APPROVAL REQUIRED
- Yes. Selecting the canonical value for a CRITICAL attribute is a C3 action reserved to an Engineer Lead.
POTENTIAL IMPACT
NEXT ACTION
- Open the canonisation screen and select the canonical value for Rated operational voltage (Ue), recording the reason. First accept at least one claim in the workbench.
An empty section emits one of the six abstention tokens rather than a blank or a reassuring sentence. CALCULATIONS says the same thing in every answer: there is no validated calculation engine in the sandbox, so no conclusion here is a computed result. A section that quietly read "none required" is how a missing calculation becomes invisible.
CONFIDENCE is derived from the trust states of the records actually used and from whether a deterministic checker has passed on the scope. It is a claim about the evidence, which means it can be argued with; a number a model produced about its own certainty cannot.
