 Build a general Python document model over the OCS host API for all **43 canvas kinds**. A kind is **complete** only after the per-kind gate below passes. Merely appearing in a converter or allowing a `layer` edit is partial coverage. Keep a property-level record of read/write, read-only, snapshot-only, and unsupported fields in the [43-kind coverage ledger](plugin-host-model-coverage-ledger.md). Do not resume the separate Lisp-to-Python conversion work.
 
-As of 19 September 2026, the OCS fork branch `plugin/host-model-api` is pushed at `db61379b` in `felixriestra/OpenCADStudio`; the PandoraBox adapter on `main` is pushed at `d0cc85e` in `felixriestra/PandoraBox`. Host API is v7. The Python feature has mapped writes for 16 initial geometry kinds plus **update-only** `Insert`; this is **not** 17 completed kinds. The other 26 canvas kinds have only `layer` writes through the document model. All 43 have raw typed snapshots. There are three internal records and two opaque fallbacks outside the 43 canvas kinds.
+As of 19 September 2026, the current AttributeDefinition increment is OCS commit `5b854bd1` on `plugin/host-model-api` and PandoraBox commit `bb259ff` on `main`. Host API is v7. The Python feature has explicit writes for **20 of 43** canvas kinds: 19 are creatable and `Insert` remains update-only. This is **not** 20 completed kinds: only Tolerance and Shape pass every completion gate. AttributeDefinition passes its host and real IPC lifecycle but remains short of `Complete` because the pinned acadrust DXF reader drops optional ATTDEF fields. The other 23 canvas kinds have only `layer` writes through the document model. All 43 have raw typed snapshots. There are three internal records and two opaque fallbacks outside the 43 canvas kinds.

 ## Handoff start point
 
-Start with the **Phase 8 integration harness and coverage ledger**. Re-evaluate the existing 17 mapped kinds against the strict completion gate. Then take `Tolerance` as the first new kind, unless its required style or persistence path is blocked; record that and proceed to `Shape`. Keep the exact remaining-kind table above as the queue and update statuses with evidence after each increment.
+Continue with **AttributeEntity**, using the existing block fixture and new creation-time `owner_handle` support. Its owner must be a real linked `Insert`, and the test must preserve sequence/attribute references through edit, deletion, undo/redo and both file formats. AttributeDefinition is mapped and integration-tested but remains open at W: pinned acadrust `568a12c` loses optional ATTDEF fields such as width factor on DXF read. Do not mark it complete until that dependency is fixed and the full property state passes DXF save/reopen. Keep the exact remaining-kind table above as the queue and update statuses with evidence after each increment.

 - `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`.
+- Added creation-time `owner_handle` to the generated document-model adapter. It is present in snapshots and accepted by `doc.create_entity`, but rejected after creation; host transactions independently reject owner changes. Generic host validation now requires a non-null canvas owner to resolve to a block record, except `AttributeEntity`, whose owner may be an `Insert`.
+- Mapped stable AttributeDefinition fields and validated tag, placement, normal, height, width, angles, text style, line count and block ownership. `embedded_mtext` stays snapshot-readable but unmapped so partial Python edits preserve its linked R2018+ layout payload.
+- `staged_python_attribute_definition_lifecycle_over_real_ipc` passes the real create/read/edit/delete/undo/selection/render/validation/portable-build path using a structurally valid block and linked Insert. Full DWG state and core DXF geometry survive reopen; deletion stays absent after both formats. OCS also stopped double-converting ATTDEF/ATTRIB DXF rotation already converted by acadrust.
+- AttributeDefinition remains **Integration-tested / DXF blocked**, not Complete: acadrust `568a12c`'s ATTDEF DXF reader does not restore optional AcDbText fields including width factor. The real test and ledger record that exact W-gate gap. The queue now continues with `AttributeEntity`.

 # 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`.

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.
