Scope of this release

This release does not prove Erdős #68, #243, #249, #251, #257, #269, #1041, or #1049. All eight remain open; their papers give checked results and surviving obligations. Claims apply only to the source and dependencies at the immutable formal-source checkpoint in docs/claims.json. The last release tag remains the citation identity and can differ from that checkpoint.

Mathematical proof authority is Lean source at that declared checkpoint after checking by the pinned Lean kernel. Unreleased work, private repositories, generated prose, provider output, and hidden proof sketches are not part of the public proof artefact. Work later than the declared checkpoint is out of scope even if it checks locally; a later tagged release is a separate citation and release action, not a substitute for an exact proof-source identity.

What the corpus is, by shape

Size is not evidence. The semantic graph classifies every statement; re-derive these with python3 scripts/query_semantic.py <shape>.

Shape Count Meaning
nonrecurring 283 substantive content, weighted to #257 (168) over #249 (88)
classical 101 already in the literature or matched to prior art; formalisation value only
bare-equivalences 32 restatements, labelled by this project’s own audit

Neither count asserts novelty: nonrecurring means a statement does not recur inside this corpus, not that it is new to mathematics. That judgement is a human number theorist’s, and no query here supplies it.

The K = 240 denominator exclusion is the classical Farey/mediant bound on a committed window. Its improvement over that argument is zero and the window length is free: python3 scripts/check_farey_denominator_scaling.py reproduces the formalised constant, then returns a 2,406-digit bound in a fraction of a second. Cite it as a finite computation, never as progress.

Exact open propositions

Machine-resolvable open propositions:

  • remaining_open.erdos_249_irrationality: python3 scripts/query_corpus.py --open remaining_open.erdos_249_irrationality
  • remaining_open.unbounded_certificate_supply: python3 scripts/query_corpus.py --open remaining_open.unbounded_certificate_supply
  • remaining_open.half_value_membership: python3 scripts/query_corpus.py --open remaining_open.half_value_membership
  • remaining_open.twenty_one_permanent_affine_supercapacity: python3 scripts/query_corpus.py --open remaining_open.twenty_one_permanent_affine_supercapacity
  • remaining_open.universal_257_all_infinite_supports: python3 scripts/query_corpus.py --open remaining_open.universal_257_all_infinite_supports

Finite instances, conditional reductions, cited neighbours, and named infinite-support families do not discharge these propositions. Only a future claim transition recorded against the exact identifier, with the evidence required by docs/methodology.json, can change this boundary.

Machine identifiers

These identifiers are the machine-readable form of the scope statement above. They are declared once in docs/claims.json and cross-checked against this file by scripts/check_release.py, which fails when any public surface drifts from them.

Identifier Public meaning
not_erdos_249_solution The release does not settle Erdős #249
not_erdos_257_solution The release does not settle the universal Erdős #257
not_publication_authority The release is not itself a peer-reviewed publication record
not_private_root_equivalence The release is not asserted to be equivalent to any private development
not_provider_proof_authority Provider or model output is not proof authority; the Lean kernel check is
not_hidden_proof_body_authority No unpublished proof sketch or hidden artefact carries proof authority
