 - ✅ CLI global flag passthrough now preserves subcommand options, letting `agent describe` and palette routines accept both space-separated and `--flag=value` styles alongside the updated help text.
 - ✅ `agent describe --format yaml` writes catalog data end-to-end; JSON format also working correctly.

 - Updated agent resource description to include listing and diffing capabilities
 - Regenerated `docs/api/z3ed-resources.yaml` with new agent actions
 
+**ProposalDrawer GUI Component** (Completed Oct 1, 2025):
+- ImGui right-side drawer for proposal review (AW-03)
+- Split view: proposal list (top) + detail view (bottom)
+- List view: table with ID, status, prompt columns; colored status indicators
+- Detail view: collapsible sections for metadata/diff/log; syntax-aware display
+- Action buttons: Accept, Reject, Delete with confirmation dialogs
+- Status filtering (All/Pending/Accepted/Rejected)
+- Integrated into EditorManager with Debug → Agent Proposals menu
+- Accept/Reject updates ProposalRegistry status
+- Delete removes proposal from registry and filesystem
+- TODO: Implement actual ROM merging in AcceptProposal method
+
+**CMake Build Integration**:
+- Added `cli/service/proposal_registry.cc` and `cli/service/rom_sandbox_manager.cc` to all app targets
+- Fixed linker errors by including CLI service sources in:
+  - `yaze` (main GUI app)
+  - `yaze_emu` (emulator standalone)
+  - `yaze_core` (testing library)
+  - `yaze_c` (C API library)
+- All targets now build successfully with ProposalDrawer dependencies
+
 **Architecture Benefits**:
 - Clean separation: RomSandboxManager (file ops) ↔ ProposalRegistry (metadata)
 - Thread-safe with mutex protection for concurrent access
 - Extensible design ready for ImGui review UI (AW-03)
 - Proposal persistence enables post-session review and auditing
 - Proposal-centric workflow enables human-in-the-loop review
+- GUI and CLI both have full access to proposal system
 
 **Next Steps for AW Workstream**:
-- AW-03: ImGui drawer with accept/reject controls
+- Test ProposalDrawer in running application
+- Complete ROM merging in AcceptProposal method
 - AW-04: Policy evaluation for gating mutations
 - AW-05: `.z3ed-diff` hybrid format design
