Evidence Attachment
Attach a piece of evidence to a claim with a typed relationship edge.
Tool
vault_add_edge + vault_search
Protocol
- Search vault for the target claim page and the evidence source page
- 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)
- Add edge with metadata:
edge_type: supported_by | contradicts | related_to
evidence_quality: strong | moderate | weak
directness: direct | indirect | analogical
- If evidence source page doesn't exist, create it first via wiki-ingest-source pattern
- 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 }
