Complete Shape host model coverage

 - Added `doc.create_entity(kind, **properties)` and `doc.delete_entity(entity_or_handle)` to the high-level Python document model. Unit tests cover forwarding and managed identity fields. The real staged-plugin Line lifecycle now uses these methods rather than low-level `ocs.add`/`remove_entity`.
 - Closed the first new-kind increment for `Tolerance`. The host coverage catalog now maps insertion point, direction, normal, text, dimension style name, text height, and gap; validates geometry and document style references; keeps the style handle read-only; and leaves the undocumented DWG short unmapped. The thin adapter adds generated conversion plus stale style-handle clearing when the style name changes.
 - `staged_python_tolerance_lifecycle_over_real_ipc` passes the full C/R/E/D/U/I/W/V/P gate with the actual runner: high-level create/read/transaction edit/delete, live canvas selection, undo/redo, invalid direction and missing style rollback, untouched-field preservation, and DWG/DXF reopen. Tolerance is recorded as **Complete** in the ledger. The queue now continues with `Shape`.
+- Closed `Shape` with a generated SHX fixture and a real shape-file `TextStyle`. Host-owned binding resolves the Python style name to the stable table handle required by DWG; validation rejects missing/non-shape styles and invalid geometry. The adapter maps all stable shape fields and keeps the bound style handle read-only.
+- `staged_python_shape_lifecycle_over_real_ipc` passes C/R/E/D/U/I/W/V/P through the actual runner, checks the real SHX linework before and after DWG/DXF reopen, and proves that invalid size/style edits remain atomic. The DXF renderer fallback now searches named `is_shape_file` styles as well as legacy unnamed styles. Shape is **Complete**; the queue now continues with `AttributeDefinition`.

 # 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: **18 of 43 canvas kinds have explicit geometry writes** (17 creatable, plus update-only `Insert`), **1 kind is complete**, and 25 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.
