Evidence Attachment

Attach a piece of evidence to a claim with a typed relationship edge.

Tool

vault_add_edge + vault_search

Protocol

1. Search vault for the target claim page and the evidence source page
2. Determine relationship type:
   • supported_by — evidence directly supports the claim
   • contradicts — evidence directly contradicts the claim
   • qualifies — evidence limits the scope or adds conditions (use related_to edge)
3. Add edge with metadata:
   • edge_type: supported_by | contradicts | related_to
   • evidence_quality: strong | moderate | weak
   • directness: direct | indirect | analogical
4. If evidence source page doesn't exist, create it first via wiki-ingest-source pattern
5. Inline wikilink: Ensure the evidence page body contains [[dir/slug]] pointing to the claim (dir/slug = target path minus .md). Place inline at semantically relevant location. Skip if already present.

HARD-GATE

Must specify evidence quality and directness. "Supported_by" without quality assessment is not allowed.

Yield

Returns: { claim: string, evidence: string, edge_type: string, quality: string }
