Footnotes

The graph resolves explicit, auto-numbered, labeled auto-numbered, and symbol footnotes together with citations.

<?php
use Alto\Rst\Reference\DefinitionKind;
use Alto\Rst\Reference\ReferenceType;

$footnotes = $graph->definitions(DefinitionKind::Footnote);
$citations = $graph->definitions(DefinitionKind::Citation);
$references = $graph->references(ReferenceType::Footnote);

Display labels belong to definitions, so an unreferenced automatic footnote still receives a stable label. Incoming indexes connect every resolved occurrence to its definition.

Rendering and conversion reuse the graph rather than resolving labels again. Missing, duplicate, or ambiguous definitions stay visible through reference problems and conversion reports.
