KCAE.SOURCE:1 - Problem frame

Use this when documents must become searchable or machine-readable, when a hit cannot be opened reliably, or when extracted text can lose a decisive relation. The governed object is the relation between an exact source edition, its extracted/segmented representations and obtainable reading context. The result is a source inventory and reader that can return that context with known fidelity limits. A clean, fully addressable source already sufficient for the use needs no new extraction pipeline.
