# Security and UX Seam Review
2+
3+
## Component Integration Points
4+
5+
### 1. TUI ↔ Config File (`config.toml`)
6+
7+
**Security:**
8+
- ✓ Config file in user home (~/.config/), not world-readable
9+
- ✓ No credentials stored in config (rclone handles auth separately)
10+
- ⚠ **TODO**: Add config file validation before parsing
11+
- ⚠ **TODO**: Add file permission check (should be 0600)
12+
13+
**UX:**
14+
- ✓ TUI reads existing config on startup
15+
- ⚠ **TODO**: Show warning if config has syntax errors
16+
- ⚠ **TODO**: Add config file backup before overwrite
17+
18+
### 2. TUI ↔ systemd Services
19+
20+
**Security:**
21+
- ✓ Services run as user (not root)
22+
- ✓ Services use `NoNewPrivileges=true`
23+
- ✓ `ProtectSystem=strict` limits writes
24+
- ✓ Generated services go to user's systemd dir
25+
26+
**UX:**
27+
- ✓ Clear feedback on apply success/failure
28+
- ⚠ **TODO**: Show diff before applying changes
29+
- ⚠ **TODO**: Add rollback capability
30+
31+
### 3. Overlay Daemon ↔ rclone RC
32+
33+
**Security:**
34+
- ✓ Connects only to localhost
35+
- ✓ Timeouts on RC requests (2 seconds)
36+
- ⚠ **TODO**: Add authentication to RC if exposed
37+
- ⚠ **RISK**: RC port could be accessed by local malware
38+
39+
**Mitigation**: Document that RC should bind to 127.0.0.1 only
40+
41+
**UX:**
42+
- ✓ Graceful degradation if rclone not responding
43+
- ✓ Status caching to reduce queries
44+
45+
### 4. Tray Daemon ↔ Health Check
46+
47+
**Security:**
48+
- ✓ Health check is read-only
49+
- ✓ No sensitive data in status output
50+
51+
**UX:**
52+
- ✓ Desktop notifications for status changes
53+
- ✓ Menu actions for common tasks
54+
- ⚠ **TODO**: Add notification throttling (avoid spam)
55+
56+
### 5. SELinux Policy ↔ File Operations
57+
58+
**Security:**
59+
- ✓ Confined rclone_t domain
60+
- ✓ Cache files labeled rclone_cache_t
61+
- ✓ Mount points labeled rclone_mount_t
62+
- ✓ Denies access to shadow/etc
63+
- ✓ Boolean tunables for debugging
64+
65+
**UX:**
66+
- ⚠ **TODO**: Add semanage commands to install.sh
67+
- ⚠ **TODO**: Document SELinux troubleshooting
68+
69+
### 6. Install Script ↔ Components
70+
71+
**Security:**
72+
- ✓ Uses install(1) with explicit permissions
73+
- ✓ Doesn't require root for most operations
74+
- ✓ SELinux/audit install prompts for sudo
75+
- ⚠ **TODO**: Verify downloaded checksums if fetching
76+
77+
**UX:**
78+
- ✓ Progress messages with colors
79+
- ✓ Uninstall option
80+
- ✓ Dry-run capability needed
81+
82+
### 7. Nautilus Extension ↔ D-Bus
83+
84+
**Security:**
85+
- ✓ D-Bus session bus (user only)
86+
- ✓ Read-only status queries
87+
- ⚠ Python extension runs in Nautilus process
88+
89+
**UX:**
90+
- ✓ Emblems update automatically
91+
- ⚠ **TODO**: Handle D-Bus connection failure gracefully
92+
93+
### 8. Watchdog Timer ↔ Services
94+
95+
**Security:**
96+
- ✓ Only restarts services that should be running
97+
- ✓ notify-send for visibility
98+
99+
**UX:**
100+
- ✓ 5-minute check interval (not too aggressive)
101+
- ⚠ **TODO**: Exponential backoff on repeated failures
102+
103+
## Privilege Escalation Review
104+
105+
| Operation | Requires sudo | Justification |
106+
|-----------|---------------|---------------|
107+
| Install binaries | No | User's ~/.local |
108+
| Install services | No | User's systemd |
109+
| Install SELinux | **Yes** | System policy |
110+
| Install audit rules | **Yes** | System audit |
111+
| Install Nautilus ext | No | User's data dir |
112+
113+

130+
131+
## Recommendations for v1.0
132+
133+
### Must Fix Before Release
134+
135+
1. **Config validation**: Add schema validation before parsing
136+
2. **Permission checks**: Verify config file permissions
137+
138+
### Should Fix (can be post-v1.0)
139+
140+
1. Add notification throttling
141+
2. Add config backup before overwrite
142+
3. Add change diff preview
143+
4. Document SELinux troubleshooting
144+
145+
### Nice to Have
146+
147+
1. Dry-run for install script
148+
2. Exponential backoff in watchdog
149+
3. RC authentication support
150+
151+
## UX Improvements Identified
152+
153+
1. **Error messages**: Make validation errors more helpful
154+
2. **First-run experience**: Detect if rclone not configured
155+
3. **Status bar**: Show sync progress in TUI
156+
4. **Keyboard shortcuts**: Document all shortcuts in TUI header
157+
158+
## Conclusion
159+
160+
The v1.0 architecture is sound with appropriate security boundaries. The main gaps are:
161+
- Input validation for config files
162+
- Some edge cases in error handling
163+
164+
Recommend proceeding with v1.0 release after adding config validation.
