+# M15-01A Status
+
+status: done
+task: Blender 5.2 RNA data-block type inventory
+updated: 2026-08-19 America/New_York
+enablingTask: false
+parityStateChange: false
+
+## Scope
+
+The pinned Blender 5.2 runtime generated a deterministic RNA inventory from the registered subclasses
+of `bpy.types.ID`. The inventory contains 29 unique sorted data-block types, stable parity IDs, the
+RNA source anchor and the runtime binary identity. No V1 release or parity status axis changed.
+
+## Evidence
+
+- `npm --prefix web run test:blender-rna-inventory` passed after regenerating in a fresh temporary
+  directory with `build_blender_5.2.0/bin/blender`.
+- Checker output: `blender-rna-datablock-inventory-ok count=29 blender=5.2.0 LTS inventory=98e6c2ebc9f62647b43fb06eff178bef02db06516f6ac87048ae81fcf2d8e792 next=M15-01B`.
+- `npm --prefix web run typecheck` and `git diff --check` passed.

+## Next Task
+
+`M15-01B`: Blender 5.2 operator idname, poll context and property inventory.
+
+## Rollback
+
+Remove the RNA generator, checker, inventory, report, manifest, package command and this status/task
+entry; restore `M14-04H` as the queue tail.
