 # OCS canvas kind coverage ledger
 
-Use with [the completion plan](plugin-host-model-completion-plan.md). This ledger is current as of 19 September 2026: **19 of 43 canvas kinds have explicit geometry writes** (18 creatable, plus update-only `Insert`), **2 kinds are complete**, and 24 remain layer-only. `Mapped` means at least one non-layer field is exposed for Python writes; it does **not** mean the kind passes the completion gate. `Update-only` means Python creation is unavailable. `Layer-only` means raw inspection and canvas layer edits exist, but geometry is not mapped. Record actual evidence or a blocking issue before changing any status to `Complete`.

 Completion gate codes: **C** = create through Python document model; **R** = read; **E** = edit defining geometry and another property; **D** = delete; **U** = undo/redo and atomic failure; **I** = real IPC plus GUI/canvas pick or observable behavior; **W** = DWG and DXF save/reopen; **V** = invalid-input checks and untouched-field/reference preservation; **P** = portable H7 v5 build. A kind is `Complete` only when **C/R/E/D/U/I/W/V/P** all pass and its property catalog matches implementation. `Blocked` requires a specific dependency or failing fixture.

 | Insert | Update-only | Transform transaction and undo tested; Python creation, deletion, real IPC/GUI and DWG/DXF gates pending. |
 | Tolerance | **Complete** | `staged_python_tolerance_lifecycle_over_real_ipc` passes C/R/E/D/U/I/W/V/P with the staged API v7 plugin: high-level create/read/transaction edit/delete; insertion, direction, and text edits; live canvas selection; grouped undo/redo; invalid direction and missing style atomic rollback; exact untouched common/style/private-field preservation; and edited DWG plus DXF reopen. Host-owned coverage exposes placement, direction, normal, text, style name, height and gap; style handle is read-only and the undocumented DWG short remains unmapped. `tolerance_geometry_and_style_references_are_validated` and the existing Tolerance tessellation tests cover reference and rendered-frame behavior. |
 | Shape | **Complete** | `staged_python_shape_lifecycle_over_real_ipc` passes C/R/E/D/U/I/W/V/P with a generated parser-valid SHX file and a real shape-file `TextStyle`: high-level create/read/transaction edit/delete; insertion, size, rotation and width-factor edits; live canvas selection; grouped undo/redo; invalid size and missing style rollback; exact identity/style/common-field preservation; and DWG plus DXF reopen. Each live and reopened document renders the three-point SHX glyph rather than the placeholder. Host-owned reference binding writes the stable style handle needed by DWG. The DXF fallback now searches all `is_shape_file` styles, preserving named-style glyph resolution after reopen. |

+| AttributeDefinition | **Integration-tested / DXF blocked** | Host commit `5b854bd1` and adapter commit `bb259ff` map block ownership plus every stable ATTDEF field except the nested `embedded_mtext` payload, which is snapshot-readable and preserved untouched. `staged_python_attribute_definition_lifecycle_over_real_ipc` passes C/R/E/D/U/I/V/P with a real block record, Block/BlockEnd markers and linked Insert: high-level creation inside the block, readback, grouped placement/default/rotation/width edits, selection, render text, atomic tag/height/style/owner rejection, deletion persistence, and three-step undo/redo. DWG reopens with the full edited state. DXF reopens identity, ownership, tag, prompt, value, placement, height and rotation, and OCS no longer double-converts ATTDEF/ATTRIB rotation. **W remains open** because pinned acadrust `568a12c` drops optional ATTDEF fields including width factor while reading DXF; the regression test keeps this limitation explicit. `embedded_mtext` mutation also remains unsupported pending linked-layout validation. |
