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.

Status (main 2bab7b2). One row of the 2026-10-21 table is stale: §20.4.101 TABLESTYLE is no longer "block structure measured, token sequence not pinned" (#60). §20.4.101.1 (until R21) decodes on R14 to R2007 (#303): all 32 records close and the 1,896 values of the 24 R2000 to R2007 records equal the export, 0 differ (the oracle scores it, #349). §20.4.101.2 (R2010 and later) is not decoded: 20 records are skipped in the corpus run (CI run 40503137263).
The other seven rows are unchanged on
mainand stillmissing. The queue: #313 (TABLESTYLE R2010+ and CELLSTYLEMAP §20.4.102), #316 (TABLEGEOMETRY §20.4.103), #317 (TABLECONTENT §20.4.97) and #319 (ACAD_TABLE §20.4.96). In the corpus run ACAD_TABLE, TABLECONTENT and TABLEGEOMETRY are skipped (14 records each), and CELLSTYLEMAP (32).chore(corpus): record the baseline the Corpus job measured for this s…
