A row-range endpoint builds byte-addressable line record metadata: the first record starts after the representation BOM bytes · case 05
A row-range endpoint builds byte-addressable line record metadata: the first record starts after the representation BOM bytes.
Case contract
Build a bounded row index over UTF-8 text. A leading UTF-8 BOM is excluded from records but occupies3 representation bytes. LF or CRLF terminates a row; blank rows are ignored. A final unterminated nonempty row is included. Return [entries,selected-hex-bodies], with each entry [absolute-byte-start,content-byte-count,terminator-byte-count]. Enforce a per-record byte cap and nonnegative selected row indices. Selection order and multiplicity are meaningful.
Why this case matters
Range responses combine representation identity, conditional requests, framing, and partial-object state.
