Migration guide

Historical HDF conversion features reconciled

PRESERVED

Reader adoption doctrine: easy opening and source portability.

HDF Converter/Resizer and universal capture funnel became the current free Converter and staged migration bridge.

Batch conversion, exception handling and migration reporting belong to Bulk Document Conversion.

Watermarking, multilingual Miller and specialized capture remain optional extensions, not core semantics.

Industrial batch compression, handwriting fidelity and legacy-format breadth remain archaeology-delta backlog items.
