EVERYTHING SOUNDS EQUALLY CERTAIN
Believed. Measured. Unknown.
All spoken with confidence.
A generated paragraph, a measured result and an open question arrive in the same voice, at the same size, with the same confidence. The interface has no way to say which is which, so the reader supplies the difference — usually wrongly.
How should an interface show what it actually knows?
By giving certainty a form rather than an adjective. HAUSE separates the states structurally: a Claim is a belief and carries a status mark; Evidence is a finding with its receipt, its date and its machine; a Question is what remains open, at the same size as an answer; a Refusal is what the system will not assert at all. Strip the styling away and a reader — or a machine — can still tell known from believed from unresolved.

FICTIONAL LISTENING STUDY / TEN RECORDED CHOICES
The type did not become more confident. The evidence changed what the sentence could responsibly say.
02 / HOW YOU MEET IT
Confidence is a property of the sentence, not of the system that produced it.
The summary reads exactly like the measurement. The inference reads exactly like the retrieved fact. Nothing in the layout separates a number someone measured on a named machine on a named date from a number that merely sounded right — and by the time a reader learns which was which, they have already quoted one of them.
03 / BENEATH THE SURFACE
Why the failure keeps returning.
Interfaces inherited their vocabulary from documents, where confidence was carried by prose and by knowing who was writing. Generated content breaks both halves: there is no author to know, and the prose is uniformly fluent. Ordinary design systems have states for loading, error and empty, and none for believed, measured or open — so the distinction has nowhere to live, and quietly disappears somewhere between the design review and the implementation.
TAKE THE RESPONSE WITH YOU
Give it a form.
Claim
An assertion that knows it must answer to evidence.
Evidence
Rows of labelled findings with status marks — receipts, not decoration.
Question
An open question given the same typographic dignity as an answer.
Refusal
Fail-closed rendered as design language, not as an error state.
Agreement
N independently-derived values that must be identical — with a FAIL row.

An argument is a published object: dated, versioned, and referenceable — which is the subject of one of these pages and the practice of all of them.
