How statement and proof provenance work
The first chip identifies the source of the statement or construction; the second identifies the source of its local proof or verification.
- Literature-sourced — the exact statement appears in a cited source; only wording and notation differ.
- AI-adapted — a semantically identical restatement of literature-sourced material, modulo indexing, notation, and boundary cases adopted by the library.
- AI-generated — a genuinely novel statement formulated by AI, with no source for the claim itself.
These labels describe origin, not correctness: citations and verification chips remain separate evidence.
A finite discrete space is already its Stone–Čech compactification
Example
Let be a finite set with the discrete topology. Then its Stone–Čech compactification is itself.
Facts & Assumptions
Given: A finite discrete space .
A finite topological space is compact (Open cover, subcover, and compact topological space; a compact subset is a subspace that is compact in its own right).
Verification
Every two distinct points of a discrete space have disjoint singleton neighbourhoods, so is Hausdorff; it is compact by [L1].
The Stone–Čech compactification of a compact Hausdorff space adds no points applied to step 1.1 gives the claim.
