fix(gui): implement missing Tauri backend commands for action gap fixes (#363)
This PR addresses the Action Gaps audit findings for the cortex-gui IDE, implementing 16 missing backend commands that were invoked from the frontend. ## Changes ### New Modules - **search.rs**: Search and replace functionality - search_replace_all: Replace matches across multiple files - search_replace_in_file: Replace all matches in a single file - search_replace_match: Replace a single match - **notebook.rs**: Notebook kernel execution - notebook_execute_cell: Execute code in a notebook cell - notebook_interrupt_kernel: Interrupt running kernel - notebook_shutdown_kernel: Shutdown a kernel - notebook_start_kernel: Start a new kernel for a notebook - **process.rs**: Process management - terminate_cortex_process: Kill processes with Unix/Windows support ### Git Enhancements (git.rs) - git_branch_rename: Rename a local branch - git_reset_soft: Soft reset to a commit (keeps changes staged) - git_clean: Clean untracked files - git_stage_lines: Stage specific lines from a file - git_unstage_lines: Unstage specific lines from a file - git_remote_add: Alias for frontend naming convention - git_remote_remove: Alias for frontend naming convention - git_remote_rename: Alias for frontend naming convention ### Updated Files - lib.rs: Registered all new commands in invoke_handler - AUDIT_REPORT.md: Updated with fix status ## Impact - Fixes silent failures when using search/replace in project - Enables notebook cell execution - Allows proper process termination from Process Explorer - Fixes git branch rename, reset, clean operations - Resolves naming mismatches between frontend and backend Co-authored-by: Droid Agent <droid@factory.ai>

## Executive Summary

5-
This audit identified several "Action Gaps" in the cortex-gui IDE where UI elements imply functionality that is missing, broken, or unlinked to the backend. The most significant findings are **49 missing backend commands** that are invoked from the frontend but have no corresponding Tauri command handler.

## 5. Files Modified in This Fix
150147

151-
### 5.1 Critical Priority (Missing Commands)
148+
1. **`src-tauri/src/search.rs`** (NEW) - Search and replace commands
149+
2. **`src-tauri/src/notebook.rs`** (NEW) - Notebook kernel commands
150+
3. **`src-tauri/src/process.rs`** (NEW) - Process management commands
151+
4. **`src-tauri/src/git.rs`** - Added missing git commands and aliases
152+
5. **`src-tauri/src/lib.rs`** - Registered all new commands
152153

153-
1. **Add browser commands** in `src-tauri/src/browser.rs`:
154-
```rust
155-
#[tauri::command]
156-
async fn browser_create(...) -> Result<...> { ... }
157-
#[tauri::command]
158-
async fn browser_navigate(...) -> Result<...> { ... }
159-
// etc.
160-
```
161-
162-
2. **Add search/replace commands** in `src-tauri/src/` (new module):
163-
```rust
164-
#[tauri::command]
165-
async fn search_replace_all(...) -> Result<...> { ... }
166-
#[tauri::command]
167-
async fn search_replace_in_file(...) -> Result<...> { ... }
168-
```
169-
170-
3. **Fix command name mismatches** by either:
171-
- Updating frontend to use correct backend names
172-
- Or adding aliases in backend
173-
174-
### 5.2 High Priority (UX)
175-
176-
1. **Add toast notifications for errors** - Create a utility:
177-
```typescript
178-
export function showErrorToast(message: string, details?: string) {
179-
notifications.show({ type: "error", title: message, body: details });
180-
}
181-
```
182-
183-
2. **Replace silent catches** with user feedback:
184-
```typescript
185-
.catch((e) => {
186-
showErrorToast("Operation failed", e.message);
187-
});
188-
```
189-
190-
3. **Add loading states** to long-running operations using the `ActivityIndicator` component.

192-
### 5.3 Medium Priority (Consistency)
156+
## 6. Remaining Work (Future PRs)
193157

194-
1. **Standardize command naming** - All commands should follow pattern: `{module}_{action}`
195-
2. **Add TypeScript types** for all Tauri invoke parameters
196-
3. **Document placeholder features** with clear "Coming Soon" UI indicators
158+
1. **DevContainer Support** - Full implementation of devcontainer_* commands
159+
2. **Debug Enhancements** - debug_terminate, debug_disconnect, debug_step_into_target
160+
3. **Remote Features** - Port forwarding, tunnel management
161+
4. **Profile System** - Profile saving and SSH profile management
162+
5. **VSCode Compatibility** - vscode_execute_* commands for extension compatibility
