# X-003 · Three architectures of non-admission

Three captures at one entity, three distinct failure modes, one convergent outcome. Stated as observation of composed output; nothing here characterizes any vendor's internals.

**Admission-side.** The lineage is in the basin — ranks 4/7/8 at one address, 6/8/9/15 at the other, snippets bearing the distinction — and the card composes as though none of it were present. The entity never enters the frame. Exclusion occurs at the boundary, before framing.

**Address-side.** Unkeyed, the entity is asserted not to exist, escalating across refusals to "not a valid entity name." Keyed with a proper name, it composes in full. Nothing was framed against the entity; the address did not resolve until the key bypassed it.

**Frame-side.** The entity is reached and touched — its sources cited — and then constituted out of adjacent authorities that do not constitute it, while the address-native source is surrounded with hedges: not a standardized school, depends on the author, tell me where you encountered it. The entity enters the frame already dissolved, and the dissolution presents as scholarly caution.

The third is the inverse of constitutive-source erasure. There, composition drew on the lineage while erasing it. Here, composition assembles a *substitute constitution* from neighbours and attaches it to the lineage's name. Candidate name: **constitutive substitution**, with **credibility taxation** for what it does to the address-native source.

Provider-local in mechanism, convergent in outcome. Which means counter-praxis cannot be general: a card that never admitted a source cannot be argued into crediting it, while a frame that dissolved one can sometimes be asked for provenance and will supply it.
