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.
The jump is well-defined on degrees
Statement
If , then . Thus is a well-defined operation on Turing degrees.
Facts & Assumptions
Given: total oracle deciders witnessing and .
Proof
Compile an -oracle program into a -oracle program that answers each simulated -query using the fixed -oracle decider for ; is computable and preserves halting on the same input.
By parameter specialization, compute an index for the program that on its own input simulates on . Then iff , so .
Repeat the construction of step 2.1 using to obtain . Therefore .

Dependency tree · two levels
5 results within two dependency steps of this one, each drawn at its shortest distance from it. An arrow runs from a result to what uses it, so the chart reads left to right and ends at this result, which carries a heavier outline. Every node is a link to that result.
