Get a technical GEO report

Returns the current status and the full result_data once the report is completed. While it is running, result_data is null and poll_after_seconds tells clients when to check again. Summaries carry output_language_code (the ISO 639-1 code an llms_txt report was requested in; null for an llms_txt report written in the website's own language, requested as auto or chosen in the app, and for every other report type); a completed llms_txt result_data also returns content_version (send it back to PATCH /technical_geo_reports/{id}/content), manually_edited_at, original_llms_txt_content and original_llms_full_txt_content (the generated files, kept from the first manual edit in the app, the API or MCP) and metadata.output_language_code.
