Verify Claims Against Sources

Corroborate or contradict a specific claim using external source

Building evidence graphs when individual claims must be corroborated with independent sources and conflicts must be discovered before synthesis.

• · Claim ID (from claims.json)
• · External URL (documentation, blog, source code, metrics)

• · Witness claim (witness_claim.id, type, relationship, evidence tier)
• · Classification: full_support / partial_support / partial_contradiction / full_contradiction
• · Updated claims.json with new witness entry
• · Git commit: 'wheat: /witness <claim_id> — added <witness_ids> (<relationship>)'

• · Web fetch (read external source content)
• · @grainulation/wheat CLI (claim compilation)

• · claims.json exists and is valid JSON
• · External URL is accessible
• · Claim ID exists in claims.json
• · Wheat compiler installed

• · URL returns 404 = source is dead or moved
• · Source is behind paywall = cannot access full content
• · Source is circular (cites same original source) = not independent evidence
• · Claim relationship ambiguous = witness created but marked unclear
• · wheat compile fails = claims.json syntax error

• · Enforces anti-rationalization checks (reputation != quality, confirmation != corroboration)
• · Classifies evidence tier by source type (official docs > web > production metrics)
• · Auto-detects conflicts via wheat compiler after adding witness
• · Requires exact quote from external source, not paraphrased claim
