+# Borealis Reverse VPN Tunnel Work — Handoff Prompt
+
+You are resuming work on Borealis' WireGuard-based reverse VPN tunnel migration in
+`d:\Github\Borealis`. You should assume no prior context. Start by reading `AGENTS.md`
+and these docs (order matters):
+
+- `Docs/Codex/BOREALIS_AGENT.md`
+- `Docs/Codex/BOREALIS_ENGINE.md`
+- `Docs/Codex/SHARED.md`
+- `Docs/Codex/USER_INTERFACE.md`
+- `Docs/Codex/Reverse_VPN_Tunnel_Deployment.md`
+
+Do not implement Linux yet.
+
+## Current Status (What Is Working)
+
+- WireGuard tunnel comes up and the PowerShell VPN shell connects successfully.
+- Agent log confirms: start request received, client config rendered, session started,
+  and a shell connection accepted from `10.255.0.2`.
+- Engine log shows WireGuard listener installed, firewall rules applied, device
+  activity started.
+
+## Key Fixes Already Applied
+
+1) Port conflict fix
+   - Default VPN shell port changed from `47001` to `47002`.
+   - Updated in:
+     - `Data/Engine/config.py`
+     - `Data/Agent/Roles/role_VpnShell.py`
+     - `Data/Engine/web-interface/src/Devices/Device_Details.jsx`
+     - `Docs/Codex/REVERSE_TUNNELS.md`
+
+2) Agent role load/import failures resolved
+   - WireGuard role was failing to load due to `signature_utils` import path and a
+     dataclass crash.
+   - Added `sys.path` insertions in role manager to make helpers importable:
+     - `Data/Agent/role_manager.py`
+     - `Agent/Borealis/role_manager.py`
+   - Added fallback import in WireGuard role:
+     - `Data/Agent/Roles/role_WireGuardTunnel.py`
+     - `Agent/Borealis/Roles/role_WireGuardTunnel.py`
+   - Replaced `@dataclass SessionConfig` with a plain class in both roles to avoid
+     `AttributeError: 'NoneType' object has no attribute '__dict__'`.
+
+3) VPN shell read-loop noise suppressed
+   - The engine threw `TimeoutError` on idle shell reads; now handled cleanly.
+   - Updated in `Data/Engine/services/WebSocket/vpn_shell.py`:
+     - `tcp.settimeout(15)`
+     - Catch `socket.timeout` and `TimeoutError` and exit loop cleanly.
+
+## Logs to Know
+
+- Agent: `Agent/Logs/reverse_tunnel.log` is the primary signal for VPN tunnel and shell.
+- Engine: `Engine/Logs/reverse_tunnel.log`, `Engine/Logs/engine.log`.
+
+## What Likely Remains
+
+- Ensure Section 7 (End-to-End Validation) in
+  `Docs/Codex/Reverse_VPN_Tunnel_Deployment.md` has accurate `[x]` checkboxes for
+  completed tests.
+- Confirm UI/PowerShell web terminal behaves as expected (live output, disconnect
+  cleanup, idle timeout).
+- Validate no legacy tunnel references remain (if any cleanup missing).
+- Update docs/checklists if any step is now complete or needs clarification.
+
+## Important File Paths Touched
+
+- `Data/Engine/config.py`
+- `Data/Agent/Roles/role_VpnShell.py`
+- `Data/Agent/Roles/role_WireGuardTunnel.py`
+- `Agent/Borealis/Roles/role_WireGuardTunnel.py`
+- `Data/Agent/role_manager.py`
+- `Agent/Borealis/role_manager.py`
+- `Data/Engine/web-interface/src/Devices/Device_Details.jsx`
+- `Docs/Codex/REVERSE_TUNNELS.md`
+- `Data/Engine/services/WebSocket/vpn_shell.py`
+
+## Environment Notes
+
+- Shell: PowerShell
+- `approval_policy=never` (do not request escalations)
+- `sandbox_mode=danger-full-access`
+
+## Suggested Verification Steps
+
+- Re-run UI PowerShell connect and confirm live terminal works.
+- Check agent log for:
+  - `WireGuard start request received`
+  - `WireGuard client session started`
+  - `Accepted shell connection from 10.255.0.2`
+- Check engine log for:
+  - `WireGuard listener installed`
+  - No `Failed to connect vpn shell` warnings
+  - No `TimeoutError` stack trace after the read-loop fix.
+
+When you continue, keep `Data/Agent` and `Agent/Borealis` copies in sync where
+appropriate.
