OPC UA NodeSet Gate

Compare two complete OPC UA NodeSet2 XML documents when both fit in a single request. Pass old_nodeset_xml as the full baseline revision and new_nodeset_xml as the full candidate revision. The deterministic report returns result (COMPATIBLE, REVIEW_REQUIRED, BREAKING, or INSUFFICIENT_INPUT), old_node_count, new_node_count, issue_count, a summary keyed by change code, and issues containing code, se

Return bounded service metadata for OPC UA NodeSet Compatibility Gate. Use this only to discover deployment stage, deterministic static-analysis scope, production availability and payment status; do not use it to compare NodeSets. The result includes the shared MCP endpoint and explicitly lists which tool calls are free and which require x402 payment.

Start one temporary in-memory upload for a large NodeSet2 XML document. Call this once for the old baseline and once for the new candidate when the complete XML documents are too large for audit_nodeset_compatibility. It returns upload_id and max_total_chars. Append that document's chunks in original order with append_nodeset_chunk. Uploads expire after 15 minutes and the service allows at most fo

Append the next unmodified text chunk to a temporary NodeSet2 upload created by begin_nodeset_upload. Pass upload_id exactly as returned by begin_nodeset_upload and chunk as the next consecutive XML text segment; send every chunk in original order without overlap, omission or reformatting. On success the result returns status=OK, upload_id and cumulative received_chars; UNKNOWN_UPLOAD_ID or UPLOAD

Compare two large NodeSet2 XML revisions after both have been fully staged with begin_nodeset_upload and append_nodeset_chunk. Pass old_upload_id for the baseline revision and new_upload_id for the candidate revision. This call consumes both upload IDs, so do not reuse them afterward. The report has the same shape as audit_nodeset_compatibility: result (COMPATIBLE, REVIEW_REQUIRED, BREAKING, or IN
