Cause (Documented platform behavior): mlprogram requires iOS15+ targets; neuralnetwork cannot be used with iOS15+ targets. Fix status: documented_behavior Other error fragments: - the minimum deployment target must be at least iOS15/macOS12/watchOS8/tvOS15 Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/apple/coremltools/db4dd46b64dcaa4c636c8360b5485c18828140d8/coremltools/converters/_converters_entry.py (official_docs, unknown, documented_behavior): Validation of convert_to vs minimum_deployment_target. - https://raw.githubusercontent.com/apple/coremltools/db4dd46b64dcaa4c636c8360b5485c18828140d8/docs-guides/source/target-conversion-formats.md (official_docs, unknown, documented_behavior): Docs on ML program vs neural network formats.
