v1.4.0 — Unified Report Export & AutoML Champion Model Publishing

Added

• AutoML champion model register/publish tools (3) (#22) — register_ml_champion_model registers an AutoML pipeline automation project's champion model to the Model Repository; publish_ml_champion_model publishes it to a scoring destination; list_publishing_destinations lists the available destinations to publish to. All three drive the mlPipelineAutomation champion-model action endpoint (register/publish), shared via helpers/auto_ml_helpers.py. Brings the tool count to 45.
• export_report tool (#18) — one tool covering every synchronous Visual Analytics report export: package (zip), pdf, png, svg, csv, tsv, xlsx, and summary, for a whole report or selected report objects. Results are returned with native MCP content types — text inline for text formats, image content for png, and an embedded binary file (carrying the correct MIME type, e.g. application/zip for packages) for package/pdf/xlsx — instead of a hand-rolled base64 JSON blob. Per-format input validation enforces the API's object-count and image_size rules; binary exports larger than MAX_EXPORT_INLINE_BYTES (default 25 MiB) are refused with guidance rather than streamed through the model context; and a Viya HTTP error is surfaced as a structured export_failed result instead of a raised exception. The format registry, validation, and request execution live in helpers/report_export_helpers.py so the tool stays a thin wrapper.

Changed — BREAKING

• export_report_package has been replaced by export_report. The old tool hit the wrong route (/visualAnalytics/getExportedReportPackage/{id}/package, the operationId rather than the path) and sent reportObjects as a JSON body on a GET. Use export_report with export_format="package"; report objects are passed via report_objects.

Removed — BREAKING

• get_report_image has been removed, superseded by export_report. It used the reportImages service to return an async job descriptor (not the image itself) for a report section thumbnail. export_report with export_format="png" or "svg" renders the whole report or a single object and returns the actual image bytes as native MCP content.
