resolve_row(window_id, buffer, source_version, row, row_id, utf16_offset)

Resolves one already-located visual row through the shared source mapping.

retain(presentation, window_id, buffer, version, identity, rows)

Reuses the prior presentation only when its immutable interaction identity matches.
