Record the remaining payload kinds as blocked

Region, Body, Solid3D and Surface need a kernel-backed create/transform API
that regenerates ACIS data; Ole2Frame needs a valid embedded-storage
fixture. No opaque payload is rewritten. This completes the ordered queue.

+- Recorded `Region`, `Body`, `Solid3D`, `Surface` (queue items 17-20) and `Ole2Frame` (item 21) as **blocked**. The ACIS kinds need a host-side kernel-backed create/transform API that regenerates the payload, wires and silhouettes; the OLE frame needs a valid embedded-storage fixture. No opaque payload is rewritten. With this the ordered queue is complete: 12 kinds are fully complete, Leader, Helix, Underlay, ViewBorder and Light are mapped but blocked at DWG/DXF persistence by acadrust gaps, RasterImage and Viewport lack an oracle or linkage, and six kinds are blocked. Next work is the engine fixes behind the canary assertions, the mapped-kind audit of the 17 pre-existing kinds, and merging `origin/main`.

 | ViewBorder | **Integration-tested / blocked at W by acadrust (DXF kind)** | Writable: `min`, `max`, `center` (2-D pairs), `scale`, `rotation_angle`, `active_viewport` and `scale_handle` (both required at creation). `version` is read-only. Reference rules: `active_viewport` must be an existing Viewport entity and `scale_handle` an existing `Scale` object. Host validation requires finite bounds with `min` below `max` on both axes, a positive scale and a finite rotation. `staged_python_view_border_lifecycle_over_real_ipc` (shared `run_mesh_lifecycle`, driver-made viewport and scale fixtures) passes C/R/E/D/U/I/V/P and DWG W: creation, a resize/recenter/scale/rotation transaction, canvas wires, seven rejection cases plus an atomic rollback, DWG reopen and re-edit, and three-step undo/redo. **W blocker (engine, pinned by a canary):** a DXF `DRAWINGVIEW` reopens as a different, opaque entity kind rather than as a ViewBorder, so only DWG restores the typed record. Not `Complete` until DXF loading restores the typed entity. Not covered: the linked view representation and drawing-view definition records. |
 | SectionSymbol | **Blocked** | Not mapped. A valid section mark needs a `SectionViewStyle` and a `ViewRep` view-representation object that a script cannot create through the host API, and the entity stores raw point counts and flag words (`raw_point_count_90`, `raw_flags_90`, `raw_point_record_count`, `raw_view_symbol_70`) whose relationship to `points` is undocumented in acadrust and is written back verbatim by both writers, so the host cannot keep them consistent after a scripted edit without guessing. Adding the kind needs (1) host-side creation or lookup of a section style and view representation, and (2) a confirmed derivation of the raw counts from a real DWG produced by another CAD application. The kind keeps raw snapshot access and layer edits. |
 | Light | **Integration-tested / blocked at W by acadrust (DXF `cast_shadows`)** | Writable: `name`, `light_type` (1 distant, 2 point, 3 spot), `position`, `target`, `status`, `light_color`, `plot_glyph`, `intensity`, the attenuation type and limits, `hotspot_angle`, `falloff_angle`, `cast_shadows`, `shadow_type`, `shadow_map_size`, `shadow_map_softness`, `photometric_mode`, `photometric_data`; `class_version` is read-only. Host validation requires a non-empty name, a known light type, finite placement, a spot or distant target that differs from the position, non-negative intensity, angles and limits, an attenuation start not above its end, a spot hotspot not above its falloff, and a non-negative shadow map size. `staged_python_light_lifecycle_over_real_ipc` (shared `run_mesh_lifecycle`) passes C/R/E/D/U/I/V/P and DWG W: a spot light with an RGB colour, an intensity/target/position/shadow transaction that preserves the colour and untouched fields, the canvas glyph, eight rejection cases plus an atomic rollback, DWG reopen and re-edit, and three-step undo/redo. **W blocker (engine, pinned by a canary):** the DXF reader does not restore `cast_shadows`, which reopens false; colour, placement and intensity persist. Not covered: photometric web data edits and sun/skylight objects. |

+| Region | **Blocked** | Not mapped. The entity is an opaque ACIS payload (`acis_data` SAT/SAB text or binary) plus derived `wires`, `silhouettes` and, for solids, a history record. A script can neither produce a valid body nor edit one, because every geometric change needs the CAD kernel to rewrite the payload, and the handover forbids deserializing and rewriting opaque ACIS data without a proven lossless path. The only lossless edit today is the layer change the document model already supports. Adding this kind needs a host-side, kernel-backed API (create a primitive, or apply a transform, then regenerate `acis_data` with its wires and silhouettes) with a DWG and DXF round-trip that preserves the payload and history byte-for-byte for untouched bodies. |

A valid OLE frame carries a `StructuredStoragePayload` (a compound-file image of the embedded object) that a script cannot supply, so creation is impossible, and frame-geometry edits (`upper_left_corner`, `lower_right_corner`, `lock_aspect`) would be an update-only path that has no real embedded-object fixture to prove storage and aspect persistence through DWG and DXF. Adding it needs a fixture builder for a minimal valid OLE storage plus a proven round-trip of the payload; until then the kind keeps raw snapshot access and layer edits. |
