+# Refactoring Notes
 
+## Architecture Reference: debugger-cli
+
+The `debugger-cli` project at `~/git/debugger-cli` provides a good pattern for daemon-based CLIs:
+
+### Key Patterns Used
+
+1. **IPC via Local Sockets** (`src/ipc/`)
+   - Uses `interprocess` crate for cross-platform Unix sockets / Windows named pipes
+   - Length-prefixed JSON messages (4-byte little-endian length + payload)
+   - Separate `protocol.rs`, `transport.rs`, and `client.rs` modules
+
+2. **Daemon Architecture** (`src/daemon/`)
+   - `server.rs` - Main event loop with IPC listener
+   - `handler.rs` - Command routing and execution
+   - `session.rs` - State management for debug sessions
+
+3. **Clean Separation**
+   - IPC protocol defines its own `Command` enum (not reusing CLI args)
+   - Handler translates protocol commands to domain operations
+   - Session holds the actual debug adapter connection
+
+---
+
+## Implementation Progress
+
+### Phase 1: Bridge Script ✅
+- Created `src/ghidra/scripts/bridge.py` - persistent TCP server inside Ghidra
+- Implements handlers: `ping`, `program_info`, `list_functions`, `decompile`, `list_strings`, `list_imports`, `list_exports`, `memory_map`, `xrefs_to`, `xrefs_from`
+- Uses `---GHIDRA_CLI_START---` / `---GHIDRA_CLI_END---` markers for ready signal
+
+### Phase 2: Output Markers ✅
+- Updated all 8 Python scripts in `scripts.rs` with delimiters
+- Updated `headless.rs` to use marker-based extraction instead of fragile brace-counting
+
+### Phase 3: IPC Layer ✅
+- Added `interprocess` crate to `Cargo.toml`
+- Created `src/ipc/mod.rs` with:
+  - `protocol.rs` - Typed `Command` enum, `Request`, `Response` structures
+  - `transport.rs` - Cross-platform socket wrapper with length-prefixed framing
+  - `client.rs` - `DaemonClient` for CLI-to-daemon communication
+
+### Phase 4: Bridge Manager ✅
+- Created `src/ghidra/bridge.rs` with `GhidraBridge` struct
+- Manages Ghidra process lifecycle (spawn, monitor, shutdown)
+- TCP connection to Python bridge script
+- `BridgeResponse<T>` typed response handling
+- Embeds bridge.py via `include_str!` macro
+
+### Phase 5: Daemon Update 🚧
+- Status: Not yet wired up
+- Remaining: Refactor daemon to use new IPC layer and bridge
+
+### Phase 6: Typed Responses ⚙️
+- `BridgeResponse<T>` created in `bridge.rs`
+- Remaining: Update all response handling
+
+### Phase 7: GUI Integration (Optional)
+- Status: Not started
+- Future work
+
+---
+
+## Files Created/Modified
+
+### New Files
+- `src/ghidra/scripts/bridge.py` - Persistent Python bridge server
+- `src/ghidra/bridge.rs` - Rust bridge manager
+- `src/ipc/mod.rs` - IPC module root
+- `src/ipc/protocol.rs` - Typed protocol definitions
+- `src/ipc/transport.rs` - Socket transport layer
+- `src/ipc/client.rs` - Daemon client
+
+### Modified Files
+- `Cargo.toml` - Added `interprocess` crate
+- `src/main.rs` - Added `mod ipc`
+- `src/ghidra/mod.rs` - Added `mod bridge`, `#[derive(Debug)]` on `GhidraClient`
+- `src/ghidra/scripts.rs` - All scripts now have output markers
+- `src/ghidra/headless.rs` - Marker-based JSON extraction
+
+---
+
+## Remaining Work
+
+To complete the refactoring:
+
+1. **Wire up bridge to daemon** - Modify `daemon/mod.rs` to hold `GhidraBridge`
+2. **Route commands through bridge** - Update `daemon/queue.rs` to use bridge instead of spawning headless
+3. **Switch to IPC layer** - Replace TCP RPC with local socket IPC
+4. **Remove one-shot execution** - Clean up legacy headless spawning code
+5. **Manual testing** - Test with actual Ghidra installation
+
+---
+
+## Build Status
+
+```
+✅ cargo check - PASSED
+✅ cargo test - 30 passed, 1 pre-existing failure (test_parse_hex)
