Classes the spec does not prescribe: VISUALSTYLE, MATERIAL, surfaces, lights and the rest #152
Description
Spec: none: these classes are absent from v5.4.1, so each field list is derived from bytes (ARCHITECTURE §7d) and held to the same bar as a prescribed one.
Classes and their state on main (2026-10-21)

Acceptance, for every class above
- The field list is derived and documented in ARCHITECTURE.md, with how it was derived
- It closes on every corpus record of 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
- Its row in docs/spec-coverage.md moves to

Status (main 2bab7b2; CI run 40503137263 and the oracle). Against the 2026-10-21 table in the body:
format_versionon R2013 and R2018, and Realistic's face lighting quality on R2000 to R2007, VISUALSTYLE: format_version and Realistic's face lighting quality differ from the export #250); fix(objects): VISUALSTYLE's R2013+ tail property types, as AutoCAD's DXF export lists them #251 fixed the R2013+ tail property types.main; 212 records are skipped in the corpus run (174 unscored in the oracle summary). The decoder is in PR feat(objects): decode MATERIAL from AutoCAD's own DWG and DXF output (#49, #152) #325.Queued, each decoded from AutoCAD's own DWG and DXF output and each provisional until #348's controlled drawings: #325 MATERIAL, #326 five small classes, #328 the dynamic-block evaluation objects, #329 DIMASSOC, #330 ACSH_HISTORY_CLASS and ACSH_BOX_CLASS, #331 PDFUNDERLAY, #332 SUN, #335 DATATABLE, #337 ACDB_TEXTOBJECTCONTEXTDATA_CLASS, #339 ACAD_EVALUATION_GRAPH and #341 ACSH_EXTRUSION_CLASS.
