Blocked by: these facts must be resolved before the domain can close. Each is listed in full under Facts.
Facts
Each fact keeps its value, its unit, the conditions it holds under, where it came from and how far it has been confirmed as separate fields, because they are separate claims. A value without its conditions is not the same fact, and a verdict is about the evidence for the value, not about the part.
RECOMMENDED_OPERATION
The range the manufacturer intends the part to be used in. Always narrower than the absolute maximum.
Fact: fact-dw254p-current
Value: 3 · Unit: A
Conditions: Per-contact maximum from mirrored family drawing; no independent manufacturer retrieval and no applied-current thermal result. Do not multiply this into a certified 6A connector capability.

Interactions
Behaviour that is not a property of this part alone. Each interaction names the records it spans, the conditions it holds under, and how far it has been confirmed. An interaction that spans several parts appears on every one of their pages, under the same identifier, because it is equally a fact about each.
int-dw254p-eurorack-harness
Records involved:

Cross-component rules
Rules that span several parts at once and are published in full on the integration page. Each rule's verdict below is that rule's own — it is a statement about the cross-component question, not about this part — and the exact wording of what the rule refuses to conclude is published with the rule itself.

Legend
What the recorded terms on this page mean, in ordinary words. The exact terms above are the ones that count; these descriptions explain them and never replace them.
Verdict
| Recorded term | What it means |
|---|---|
CONFIRMED - distributor identity only | A distributor listing confirms which part this is, and nothing more. It carries no electrical, thermal or lifetime authority. |
NEEDS BENCH | Cannot be settled from documents. It needs measurement on real hardware before it can be relied on. |
PASS - primary-source confirmed | Confirmed against the manufacturer's own document for this exact part. |
UNSOURCED | No accepted source backs this value yet. Treat it as a claim, not a fact. |
Provenance
| Recorded term | What it means |
|---|---|
DISTRIBUTOR-IDENTITY | Taken from a distributor listing. Identity information only. |
PRIMARY-SPEC | Taken from the manufacturer's own specification document. |
PROJECT-CHOICE | A decision made by this project. No vendor asserts it. |
UNVERIFIED | Recorded, but not yet backed by an accepted source. |
Fact class
| Recorded term | What it means |
|---|---|
PROJECT_STATE | A value this project recorded about how the part is used here — a chosen operating point, a net assignment, or a derived figure. Not a manufacturer specification. |
