closes comes from the boundary checks on the local 19-file corpus (STATUS.md, 2026-08-30). It is re-measured on the public corpus in CI by the 0.2.0 measurement epic, and no section is complete until its values equal AutoCAD's own DXF export.
Acceptance, for every section above
- Every field of its prescription is read, with every version branch the section names
- Where the section prints an example, its bytes are a committed fixture and decode to the values printed
- The field list ends on the record's exact data-stream boundary (and string/handle-stream boundaries on R2007+) on every corpus record of the type, on every release band
- Every value equals AutoCAD's DXF export of the same drawing, matched by handle (DXF group 5), with the scorer from the oracle epic
- The corpus holds at least one record of the type on each release band, R13 to R2018; a band without one is recorded on the corpus epic, not assumed
- Its row in docs/spec-coverage.md moves to
complete, with the evidence linked

A subtask becomes its own issue when someone picks it up; that issue quotes the section's field list and names the corpus records it is measured on.
