Mathlib source occurrence

instDenselyOrderedForall

A source-pinned catalogue entry. MathGraph indexed these exact bytes and structural references; it did not independently check this declaration as a proof.

This text is bound to the statement digest above. Parsing and indexing it does not establish proof validity, informal fidelity, implication or equivalence.

Lifecycle and research maturity are UNKNOWN in this source catalogue. The source pin is historical; absence of a newer change or revocation has not been checked.

Declared structural neighborhood

1 incoming and 2 outgoing relations occur in the bounded projection below. DECLARES, IMPORTS_MODULE and TYPE_REFERENCES are structural source relations only. Each explicitly sets logical implication and semantic equivalence to false.

Omitted structural references

  • Preorder — named target outside this selected catalogue slice
  • Preorder.toLT — named target outside this selected catalogue slice
Module declarations omitted
148
Module imports omitted
12
Module type references omitted
1687

Omissions are preserved rather than converted into absent relations. Out-of-slice targets remain unsupported by this projection.

Manifest · Module shard · Search export

This replay does not fetch Mathlib, rerun Lean, authenticate GitHub, check current applicability, or grant action authority. It validates the pinned publication contract and returns only its bounded source-indexing result.

Bounded source neighborhood

Navigate exact declared source structure around this occurrence. The projection is capped at 8 objects and 12 relations; named omissions and out-of-slice references stay visible above.

Declared objects and relations

Presentation projection · authority NONE · not a certificate, proof, or verifier

Position and proximity organize this view only. Every arrow repeats an exact structural relation whose logical implication and semantic equivalence flags are false.

Filter declared relation types

4 of 4 objects · 5 of 5 relations · omitted: 0 objects, 0 relations

This page is capped at 8 objects and 12 relations. Counts preserve the complete one-hop selected scope, including named omissions.

Display-only traversal

Follow only the currently displayed declared arrows. This is not proof search, verification or support closure.
