+# M15-01E Status
+
+status: done
+task: Blender 5.2 editor, space, region, workspace and keymap inventory
+updated: 2026-08-19 America/New_York
+enablingTask: false
+parityStateChange: false
+
+## Scope
+
+The pinned Blender 5.2 runtime generated deterministic editor inventories for 19 Area types, 17
+Region types, 19 Space types, 16 concrete Space RNA classes, and 13 Workspace modes. The initialized
+factory keyconfig contributes 280 keymaps and 3,228 keymap items, including modal event items with
+empty operator ids. This is a machine baseline only and does not claim editor or keymap parity.
+
+## Evidence
+
+- `npm --prefix web run test:blender-editor-inventory` passed after temporary regeneration.
+- Checker output: `blender-editor-inventory-ok areas=19 regions=17 keymaps=280 items=3228 inventory=6293b5c5bc23c8a73fdde553a5173ac1da25a08c8158af5ec81f4b0f864a5064 next=M15-01F`.
+- `npm --prefix web run typecheck` and `git diff --check` passed.

+## Next Task
+
+`M15-01F`: same-level inventory for Main, Scene, Mesh, Depsgraph and existing V1 core slices.
+
+## Rollback
+
+Remove the editor generator, checker, inventory, report, manifest, package command and this status
+page together. Restore `M15-01D` as the queue tail without changing the format inventory.
