Add receipt_format to stamp and verify. Omitted → text; receipt|PDF-Receipt → PDF; JSON-Receipt → JSON; MD|MD-Receipt; CSV|CSV-Receipt; TSV|TSV-Receipt. Stamp always returns receipts[] and adds artifacts[] in the chosen format. Stdio writes ~/.verae/receipts (0600); public MCP returns content_text/content_base64 only. Verify accepts inline receipt or receipt_path (stdio), parses id, and re-emits an artifact. Vendors pdfcert (+ slim statuslang, gofpdf) for CERT-01 PDF. Also lands welcome tool and email-username helpers already wired into register/public paths.
