It contains 558 public notes, 11493 heading anchors, 846 resolved graph edges, and 1 authored Topic Maps with 8 route entries. The structured Claim/Evidence dataset contains 0 author-declared claims and 0 cited evidence references. Claims are never inferred from ordinary prose and require explicit human_reviewed: true approval in the public content source. An optional knowledge_status is author-declared and means the author's current epistemic position, not objective truth. Supported values are question, hypothesis, growing, supported, disputed, evergreen, superseded, and archive. If the field is absent, do not infer a status from prose or graph position. Use JSON heading citation fields when quoting a specific section. Do not infer that private or unpublished notes exist from unresolved public links.
