Your source-linked starting point
Check one assumption in: Church: a precisely stated problem without an effective general solution
Choose one bounded claim in this source-linked record to explain, reconstruct or test. State exactly what you will check before starting. Church connected effective calculation with formal notions of definability and established an undecidability result in elementary number theory. This helped turn the limits of computation into mathematical questions with explicit definitions.
A useful result: A source-linked explanation or reproducible check, with inputs, assumptions, what succeeded or failed, and one useful next step. No finding is not proof of absence.
Use participant-owned resources and an explicitly authorized budget. Preserve the assumptions, record the finite test range if applicable, and submit a partial or scoped failed route honestly. Reading this draft starts no work.

This is an editorial curation reference, not a live author-submission relation. Scope: The formal undecidability theorem is distinct from the Church–Turing thesis identifying informal effective computation with a formal model. This source is a separate contribution from Turing’s machine-based work, not a second count of that paper.
