Sources are not equal
A recent official source, a media paraphrase, a historical trace, product documentation, and a community comment do not share the same status or normative force. Treating them as interchangeable creates false neutrality.
Source hierarchy does not eliminate every contradiction. It prevents a system from turning mere coexistence of traces into automatic truth.
What it means to hierarchy sources publicly
Public hierarchy is not just a list of sources. It is a declaration of which surfaces are canonical, which are complementary, which document caution or conflict, and which must not ground affirmative output.
The hierarchy can remain simple. It must, however, be clear enough that a third party can understand why an answer should rely on one layer rather than another.
When arbitration must stop
A good hierarchy does not only authorise answering. It also authorises suspension. When dominant sources conflict, are stale, or permit only a conditional answer, the system must know how to stop.
Silence is not weakness here. It is the normal effect of a hierarchy explicit enough to refuse false arbitration.
The minimum condition of defence
A defensible answer is not necessarily perfect. It is at least attachable to an intelligible evidence architecture: dominant sources, secondary sources, scope limits, and non-answer cases.
Without that architecture, even a plausible answer remains fragile because no public frame exists to explain why it should have been believed or refused.
