### Description (declared)

Verify and settle VSL Settlement Receipts. Verification runs offline against published keys with no account and no network, reports every check, and never takes a key from a location inside the Receipt. Signing and settling are bound to the identity and issuer the operator configured at start; no tool takes a URL. Self-hosted MCP server over stdio: pip install sdcreceipt, then run 'sdcreceipt-mcp'. Verifies Receipt 1.0 (one ES256 issuer signature) and Receipt 1.1 (ES256 and ML-DSA-65 issuer signatures over the same digest, both required).
