+# M13-01A Status
+
+status: done  
+task: inventory Text, Python Console, autorun, driver expression, handler, and add-on entry points  
+updated: 2026-08-18 America/New_York  
+enablingTask: true  
+parityStateChange: false
+
+## Scope
+
+Pinned Blender 5.2 now has a machine-readable scripting entry inventory covering three Text
+datablocks, Python Console operators, a module-autorun request, one driver expression, 39 handler
+groups, and four add-on operators. The report records the entry source and default Web policy:
+Text is metadata-only, while Console, autorun, driver expressions, handlers, and add-on operations
+are `DENY`. This task only inventories entry points; it does not execute script text or open a
+browser scripting route.
+
+## Evidence
+
+- `build_blender_5.2.0/bin/blender -b --factory-startup --python
+  tools/web/generate-script-entry-inventory.py -- tests/files/web/m13_script_entry_v1
+  tests/golden/M13-01A/entry-inventory.json` created a fixture with internal/external Text,
+  `use_module` autorun metadata, and a driver expression without executing user code.
+- `node tools/web/check-script-entry-inventory.mjs` matched pinned runtime identity, policy and
+  semantic inventory, then regenerated the report in a fresh directory. Blender's `.blend` save
+  contains runtime save bytes that may differ between runs, so determinism is asserted on the
+  inventory and fixture byte length; the checked-in fixture hash remains bound in the manifest.
+  Output: `script-entry-inventory-ok texts=3 console=3 autorun=1 drivers=1 handlers=39 addonOps=4 deterministic=true next=M13-01B`.
+- `python3 -m py_compile tools/web/generate-script-entry-inventory.py`, Node syntax check and
+  `git diff --check` passed.

+
+## Next Task
+
+`M13-01B`: read script metadata on `.blend` open without executing arbitrary content.
+
+## Rollback
+
+Remove the generator, checker, fixture, report, manifest, and this status entry. Restore M12-07J
+as the queue tail and move the machine queue back to M13-01A. No parity ledger rollback is required.
