A row-range endpoint builds byte-addressable line record metadata: a final line without LF remains a selectable record · case 04
A row-range endpoint builds byte-addressable line record metadata: a final line without LF remains a selectable record.
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.

Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.

|---|---|---|---|
| unterminated-tail fixture 0 | null | [[[0, 1, 2], [3, 1, 1], [6, 2, 0]], ["6364", "61", "6364"]] | Failed |
