Workspace Content Graph and Schema Lineage

Build an addressed graph of supplied workspace files, package dependencies and schema references. Preserve source locations and native SignCell readouts for exact observed schema links. Up to 32 files and 64 KiB; 128 schema and 16 glossary readouts. No repository or network fetching. Schema lineage records declarations and resolution, not schema validation or source authentication.

Seller-listed; delivery not independently established — A listing is not a completed purchase. The live HTTP 402 challenge supplies current payment terms.

How to buy with x402

Send the source's unsigned request. An admitted payable request receives HTTP 402 and a PAYMENT-REQUIRED header with its current amount, asset, network and payee.
Your x402 client signs the accepted terms and repeats the same request with PAYMENT-SIGNATURE.
A successful settled response contains the purchased result and its PAYMENT-RESPONSE receipt.
