AI Claim Ledger

python -m pip install .

Verified claims require at least one supporting relationship to a syntactically valid HTTP or HTTPS source. Reports group claims by status, retain notes and source labels, and flag unused sources, disputed claims without contradictory evidence, and claims that have both supporting and contradictory evidence. The same source can be linked to multiple claims without copying its URL and title. Existing version 1 ledgers remain supported.

Version 2 uses a top-level source registry and claim-level evidence links:

{
  "version": 2,
  "sources": [
    {"id": "python-json", "url": "https://docs.python.org/3/library/json.html", "title": "Python JSON documentation"}
  ],
  "claims": [
    {
      "id": "claim-1",
      "claim": "Python includes a standard JSON encoder and decoder.",
      "status": "verified",
      "evidence": [{"source_id": "python-json", "relation": "supports"}]
    }
  ]
}
