 ## Immediate Priorities
 
 Unless the user chooses a different priority, proceed in this order:
 
-1. Implement the five missing MVP GUI components individually, with tests.
-2. Add visual REST action, event, and binding configuration.
-3. Add validation to every project save path.
-4. Implement authentication and secure secret handling.
-5. Harden the REST proxy and add sanitized execution logging.
-6. Add backend, end-to-end, and security regression tests.
-7. Reconcile and consolidate project documentation.

 ## Progress Log
 
-No work recorded yet.
+- Added Text Area, Checkbox, Radio Group, Status Panel, and Container/Card to the shared type model, palette, canvas, defaults, property editor, and Preview.
+- Kept all interactive input values in ephemeral Preview runtime state.
+- Added response-mapped `.value` support for Text Area, Checkbox, Radio Group, and Status Panel.
+- Defined Container/Card as a flat presentational card with title and body; nested component ownership is deferred beyond MVP.
+- Added a representative schema fixture covering all five components.
+- Added focused renderer and binding regression tests.
+- Validation passed: 7 suites / 433 tests, frontend production build, backend TypeScript build, and the new schema fixture.
+- User manual acceptance passed: startup, all five new component controls, Preview behavior, JSON synchronization, save/load persistence, and existing-component regression checks.
 
 ## Handoff
 
-- Last completed: Slice plan created.
-- Next action: Define component contracts and implement Text Area as the reference pattern.
-- Known blockers: Container/Card nesting behavior requires a scoped decision.
+- Last completed: All Slice 1 GUI components and validation.
+- Next action: Begin Slice 2 visual REST action, event, and binding configuration.
+- Known blockers: None for Slice 1.
