### ATX Review Prompt

**Note**: `mcp.review_enabled: true` in `.claude/itx-config.json`. The following prompt is written for an external ATX MCP review run. Hermes cannot invoke ATX MCP directly — a human must run the review separately.

```
Review the changes in PR for issue #430 (branch: issue-430).

Scope: 10 files, +418/-40 lines across backend, CLI, GUI, playbooks, and tests.

Key changes:
1. Remove HEARTBEAT.md from zeroclaw memory allowlists (Python constants + Ansible playbooks)
2. Add is_file_writable() helper to core/memory.py for allowlist validation
3. Add create-if-missing behavior to CLI edit_cmd — prompts when allowlisted file doesn't exist
4. Update GUI memory tab to show missing files with "Create" action

Focus areas for security review:
- Input validation in CLI edit_cmd (memory.py lines 352-397)
- is_file_writable() allowlist bypass potential (memory.py lines 188-209)
- Path traversal in daily-note pattern matching (memory.py lines 237-251)
- GUI state management for create vs edit flows (memory-tab.tsx)

Run: git diff main...HEAD from worktree at /home/maurice/clawrium-issue-430
```

### Manual Security Checklist

Per AGENTS.md "PR Format (Manual)" → "Security Checklist":

- [x] **No hardcoded secrets or credentials**
  - No secrets in the diff. All credentials continue to use existing credential management patterns.

- [x] **Input validation for user-provided data**
  - `is_file_writable()` validates filenames against static allowlist before allowing create prompt
  - `_validate_memory_filename()` rejects path traversal (`..`, `.`, empty components)
  - `_stdin_is_tty()` check prevents automated scripts from hanging on interactive prompts
  - `--force` flag requires explicit opt-in for non-interactive file creation
  - **Finding**: No issues. Defense-in-depth with both Python and Ansible allowlists.

- [x] **No SQL injection, XSS, or command injection risks**
  - No SQL in scope
  - GUI uses React JSX (auto-escapes) — no raw HTML injection
  - Filenames are validated against allowlists before any filesystem operations
  - No shell command construction with user input
  - **Finding**: No issues.

- [x] **Dependencies are from trusted sources**
  - No new dependencies added
  - **Finding**: N/A

### Code Quality Review

**is_file_writable() helper** (memory.py:188-209):
- Clean encapsulation of allowlist logic
- Correctly handles both static allowlist and daily-notes pattern
- Returns False for unknown claw types (safe default)

**CLI edit_cmd changes** (memory.py:352-397):
- Good UX: distinguishes "agent unreachable" from "file missing" via `get_memory_info()`
- Proper allowlist check before prompting to create
- `--force` flag for automation-friendly workflows
- Error messages are clear and actionable

**GUI memory-tab.tsx changes**:
- `isCreating` state correctly separated from `isEditing`
- Conditional fetch skip for missing files prevents 404 noise
- "Create" button vs "Save" button distinction is clear
- Missing file badge and italic styling provide good UX feedback

**Test coverage**:
- `TestIsFileWritable` class covers all key paths
- Tests for path traversal rejection in daily notes
- HEARTBEAT.md removal verified in both Python and Ansible tests

### Findings Summary

| Severity | Count |
|----------|-------|
| Critical | 0     |
| High     | 0     |
| Medium   | 0     |
| Low      | 0     |

**Result**: No blocking issues. Changes are clean, well-tested, and follow security best practices.

### Verification Commands

```bash
# Verify lint passes
make lint

# Verify tests pass (memory-related subset)
pytest tests/test_core_memory.py tests/test_registry_zeroclaw.py -v

# Verify HEARTBEAT.md removed from allowlists
grep -r "HEARTBEAT" src/clawrium/core/memory.py src/clawrium/platform/registry/zeroclaw/playbooks/
# Should only match in configure.yaml (install-time seeding)
```
