+# Plan: Firewall INPUT Fix + Device Status via WireGuard Handshake
+
+## TL;DR
+> Fix two critical production issues: (1) firewall INPUT chain doesn't isolate WireGuard peers, (2) device status shows offline because it depends on Redis heartbeats instead of WireGuard handshake data.
+
+**Deliverables**:
+- WireGuard per-peer handshake status (replace Redis heartbeat dependency)
+- Firewall INPUT chain rules in code (persist across restarts)
+- ICMP + established/related accept rules for WG traffic
+
+**Estimated Effort**: Medium
+**Parallel Execution**: YES - 2 waves
+**Critical Path**: T1 (wgctrl) → T2 (SyncToDB) → T3 (INPUT rules) → F1-F4
+
+---
+
+## Context
+
+### Original Request
+1. Device `gogo2` connected via WireGuard (peer shows handshake in `wg show`) but dashboard shows offline (`IsActive=false`)
+2. Firewall INPUT chain rules don't work — ping from WG peer still works even with drop rules
+3. User wants a proper plan, not ad-hoc fixes
+
+### Interview Summary
+**Key Discussions**:
+- Device was created manually via API, not via device-agent → no heartbeats sent
+- Heartbeat system: device-agent → POST /api/v1/heartbeat → Redis TTL 90s → SyncToDB sets `is_active`
+- Without device-agent, no heartbeats → `is_active` stays false
+- Solution: use WireGuard handshake time from wgctrl instead of Redis heartbeats
+- Firewall: `table ip nexusguard` INPUT chain has rules but ping still works
+- Root cause: rules not in code (manually added, lost on restart), ICMP not explicitly allowed, possible `table inet` vs `table ip` priority conflict
+
+**Research Findings**:
+- `wgmanager_linux.go:50` iterates `dev.Peers` and reads `peer.LastHandshakeTime` — but only stores MAX across all peers, losing per-peer granularity
+- `WgStatus` struct has no per-peer handshake map
+- `SyncToDB()` in `heartbeat/redis.go` checks Redis key existence → sets `is_active`
+- Dashboard reads `device.IsActive` from DB — no frontend changes needed if SyncToDB is fixed
+- `InitNetwork()` creates INPUT chain with zero rules — all rules were manual
+- `AddInputRule()` only adds `udp dport` rules — no ICMP, no established/related
+
+### Metis Review
+**Identified Gaps** (addressed):
+- INPUT chain rules must be added to `InitNetwork()` code for persistence
+- ICMP accept rule missing — only TCP/UDP explicitly allowed
+- Per-peer handshake data needed (current `GetStatus()` loses per-peer granularity)
+- Remote node devices won't have local WG data — scoped to local-only
+- Docker's `inet filter` chains must not be modified
+
+---
+
+## Work Objectives
+
+### Core Objective
+Device status reflects actual WireGuard connectivity (not Redis heartbeats), and firewall INPUT chain properly isolates WG peers.
+
+### Concrete Deliverables
+- `wgmanager` interface: new `GetPeerHandshakes()` method
+- `heartbeat/redis.go`: `SyncToDB()` uses WG handshake data
+- `nftables_linux.go`: INPUT chain rules in `InitNetwork()`
+- Production deployment with verification
+
+### Definition of Done
+- [x] Device with active WG peer shows `is_active=true` in API
+- [x] Device without WG handshake shows `is_active=false`
+- [x] `ping 10.172.21.1` from WG peer → RTO (dropped)
+- [x] TCP 8080 from WG peer → works (API access)
+- [x] UDP 51820 from WG peer → works (WG tunnel)
+- [x] Non-WG traffic → unaffected (Docker, SSH, etc.)
+- [x] Rules persist across server restart
+
+### Must Have
+- `GetPeerHandshakes() map[string]time.Time` in wgmanager
+- `SyncToDB()` matches device public keys to WG peer public keys
+- INPUT chain rules in `InitNetwork()` code (not manual)
+- ICMP accept rule for WG traffic
+- established/related accept rule for WG traffic
+
+### Must NOT Have (Guardrails)
+- NEVER `nft flush table` — project anti-pattern
+- NEVER change `policy accept` on any chain
+- NEVER modify Docker's `inet filter` chains
+- NEVER add IPv6 rules
+- NEVER remove heartbeat API endpoint (keep as fallback)
+- NEVER add new API endpoints — modify existing only
+- NEVER touch `shared/crypto/encryptor.go`
+- NEVER add per-device firewall INPUT rules (INPUT is server-level, not peer isolation)
+
+---
+
+## Verification Strategy
+
+> **ZERO HUMAN INTERVENTION** — ALL verification is agent-executed.
+
+### Test Decision
+- **Infrastructure exists**: YES (Go build, nft CLI, curl)
+- **Automated tests**: Tests-after (verify existing tests still pass)
+- **Framework**: `go build -tags dev ./...`, `nft list chain`, `curl` API
+
+### QA Policy
+Every task includes agent-executed QA scenarios.
+Evidence saved to `.sisyphus/evidence/task-{N}-{scenario-slug}.{ext}`.
+
+- **Backend**: Use Bash (curl) — API requests, assert status + response fields
+- **Firewall**: Use Bash (ssh + nft) — rule verification, counter checks
+- **WireGuard**: Use Bash (ssh + wg) — handshake verification
+
+---
+
+## Execution Strategy
+
+### Parallel Execution Waves
+
+```
+Wave 1 (Start Immediately - backend core):
+├── Task 1: wgmanager GetPeerHandshakes() [quick]
+├── Task 2: SyncToDB uses WG handshake [quick]
+└── Task 3: InitNetwork INPUT chain rules [quick]
+
+Wave 2 (After Wave 1 - deployment + verification):
+├── Task 4: Build + deploy to production [quick]
+└── Task 5: Verify all acceptance criteria [quick]
+
+Wave FINAL (After ALL tasks — 4 parallel reviews, then user okay):
+├── Task F1: Plan compliance audit (oracle)
+├── Task F2: Code quality review (unspecified-high)
+├── Task F3: Real manual QA (unspecified-high)
+└── Task F4: Scope fidelity check (deep)
+-> Present results -> Get explicit user okay
+```

+### Dependency Matrix
+
+| Task | Depends On | Blocks |
+|------|-----------|--------|
+| T1 | None | T2 |
+| T2 | T1 | T4 |
+| T3 | None | T4 |
+| T4 | T2, T3 | T5, F1-F4 |

+- **Wave 1**: 3 tasks — T1 `quick`, T2 `quick`, T3 `quick`
+- **Wave 2**: 2 tasks — T4 `quick`, T5 `quick`
+- **FINAL**: 4 tasks — F1 `oracle`, F2 `unspecified-high`, F3 `unspecified-high`, F4 `deep`
+
+---
+
+## TODOs
+
+- [x] 1. **wgmanager: add GetPeerHandshakes() method**
+
+  **What to do**:
+  - Add `GetPeerHandshakes() map[string]time.Time` to `WgManager` interface in `internal/wgmanager/manager.go`
+  - Implement in `internal/wgmanager/wgmanager_linux.go`: iterate `dev.Peers`, return map of `peer.PublicKey.String() → peer.LastHandshakeTime`
+  - Implement stub in `internal/wgmanager/wgmanager_stub.go` (returns empty map)
+  - Add test in `internal/wgmanager/` if test file exists
+
+  **Must NOT do**:
+  - Don't modify existing `GetStatus()` method
+  - Don't change `WgStatus` struct
+
+  **Recommended Agent Profile**:
+  - **Category**: `quick`
+  - **Skills**: []
+
+  **Parallelization**:
+  - **Can Run In Parallel**: YES (with T3)
+  - **Parallel Group**: Wave 1 (with T3)
+  - **Blocks**: T2
+  - **Blocked By**: None
+
+  **References**:
+  - `apps/server-core/internal/wgmanager/manager.go:27-39` — WgManager interface + UpConfig struct
+  - `apps/server-core/internal/wgmanager/wgmanager_linux.go:27-58` — GetStatus() implementation, iterates dev.Peers at line 50
+  - `apps/server-core/internal/wgmanager/wgmanager_stub.go` — Stub implementation
+
+  **Acceptance Criteria**:
+  - [x] `go build -tags dev ./...` passes
+  - [x] `GetPeerHandshakes()` returns non-empty map when peers are connected
+  - [x] Method is on both interface and implementations
+
+  **QA Scenarios**:
+  ```
+  Scenario: GetPeerHandshakes returns peer handshake data
+    Tool: Bash (go test or manual verification)
+    Preconditions: Server running with connected WG peer
+    Steps:
+      1. SSH to server
+      2. Run: docker exec nexus-guard-suite-server-core-1 ./server-core -tags dev -test.run TestGetPeerHandshakes 2>&1 || echo "verify via API"
+      3. Check wg show wg0 latest-handshakes for reference
+    Expected Result: Map contains public key → timestamp for connected peer
+    Evidence: .sisyphus/evidence/task1-peer-handshakes.json
+  ```
+
+  **Commit**: YES
+  - Message: `feat(wgmanager): add GetPeerHandshakes() for per-peer handshake data`
+  - Files: `internal/wgmanager/manager.go`, `internal/wgmanager/wgmanager_linux.go`, `internal/wgmanager/wgmanager_stub.go`
+
+- [x] 2. **heartbeat: SyncToDB uses WireGuard handshake instead of Redis**
+
+  **What to do**:
+  - Modify `SyncToDB()` in `internal/heartbeat/redis.go` to:
+    1. Query `wgMgr.GetPeerHandshakes()` (inject wgMgr into Manager or pass as parameter)
+    2. For each device, match `device.PublicKey` against WG peer public keys
+    3. If match found AND handshake within 120s → set `is_active=true`, `last_handshake=handshake_time`
+    4. If no match OR handshake > 120s → set `is_active=false`
+  - Keep Redis heartbeat recording active (don't break existing device-agents)
+  - Update `NewHeartbeatManager` to accept `wgmanager.WgManager` parameter
+  - Update `main.go` to pass `wgMgr` to heartbeat manager
+
+  **Must NOT do**:
+  - Don't remove Redis heartbeat recording (keep as fallback)
+  - Don't change the heartbeat API endpoint
+  - Don't change `RecordPing()` method
+
+  **Recommended Agent Profile**:
+  - **Category**: `quick`
+  - **Skills**: []
+
+  **Parallelization**:
+  - **Can Run In Parallel**: NO
+  - **Parallel Group**: Wave 1 (after T1)
+  - **Blocks**: T4
+  - **Blocked By**: T1
+
+  **References**:
+  - `apps/server-core/internal/heartbeat/redis.go:57-84` — Current SyncToDB implementation
+  - `apps/server-core/internal/heartbeat/redis.go:14-17` — Manager struct (needs wgMgr field)
+  - `apps/server-core/main.go:216-219` — HeartbeatManager creation (needs wgMgr param)
+  - `apps/server-core/api/devices.go:35-60` — Device List handler (reads is_active from DB)
+  - `apps/dashboard-ui/src/views/Devices.vue` — Dashboard reads IsActive from API response
+
+  **Acceptance Criteria**:
+  - [x] `go build -tags dev ./...` passes
+  - [x] Device with active WG peer → `is_active=true` in DB after SyncToDB cycle
+  - [x] Device without WG handshake → `is_active=false`
+  - [x] Redis heartbeat recording still works (existing device-agents unaffected)
+
+  **QA Scenarios**:
+  ```
+  Scenario: Device with active WG peer shows online
+    Tool: Bash (curl + ssh)
+    Preconditions: Server running, device gogo2 connected via WG
+    Steps:
+      1. SSH to server, get token: TOKEN=$(curl -s http://localhost:8080/api/v1/auth/login -X POST -H "Content-Type: application/json" -d '{"username":"admin","password":"admin123"}' | python3 -c "import sys,json; print(json.load(sys.stdin)['token'])")
+      2. Wait 35s for SyncToDB cycle
+      3. curl -s http://localhost:8080/api/v1/devices -H "Authorization: Bearer $TOKEN" | python3 -c "import sys,json; devices=json.load(sys.stdin); [print(d['Name'], d.get('is_active')) for d in devices]"
+    Expected Result: gogo2 shows True (is_active=true)
+    Evidence: .sisyphus/evidence/task2-device-online.json
+
+  Scenario: WG peer handshake data present
+    Tool: Bash (ssh)
+    Steps:
+      1. SSH to server
+      2. wg show wg0 latest-handshakes
+      3. Compare timestamp with device LastHandshake in DB
+    Expected Result: Timestamps match (within 30s)
+    Evidence: .sisyphus/evidence/task2-handshake-match.json
+  ```
+
+  **Commit**: YES (groups with T1)
+  - Message: `feat(heartbeat): use WireGuard handshake for device status instead of Redis`
+  - Files: `internal/heartbeat/redis.go`, `main.go`
+
+- [x] 3. **nftables: add INPUT chain rules to InitNetwork()**
+
+  **What to do**:
+  - In `InitNetwork()` (after forward chain rules), add INPUT chain rules via nft CLI:
+    ```
+    nft add rule ip nexusguard input ct state established,related accept comment "estab"
+    nft add rule ip nexusguard input icmp type echo-request accept comment "icmp_ping"
+    nft add rule ip nexusguard input ip saddr 10.172.21.0/24 tcp dport 8080 accept comment "wg_api"
+    nft add rule ip nexusguard input ip saddr 10.172.21.0/24 udp dport 51820 accept comment "wg_tunnel"
+    nft add rule ip nexusguard input ip saddr 10.172.21.0/24 drop comment "wg_isolation"
+    ```
+  - Each rule must be idempotent (check comment before adding)
+  - Use `detectWGSubnet()` (already exists) for WG subnet detection
+  - Remove old manual rules on production server during deployment
+
+  **Must NOT do**:
+  - Don't change `policy accept` on INPUT chain
+  - Don't add rules to Docker's `inet filter` chains
+  - Don't add IPv6 rules
+
+  **Recommended Agent Profile**:
+  - **Category**: `quick`
+  - **Skills**: []
+
+  **Parallelization**:
+  - **Can Run In Parallel**: YES (with T1)
+  - **Parallel Group**: Wave 1 (with T1)
+  - **Blocks**: T4
+  - **Blocked By**: None
+
+  **References**:

+  - `apps/server-core/internal/firewall/nftables_linux.go:46-62` — detectWGSubnet() function
+  - `apps/server-core/internal/firewall/nftables_linux.go:156-174` — AddInputRule/RemoveInputRule (existing pattern)
+
+  **Acceptance Criteria**:
+  - [x] `go build -tags dev ./...` passes
+  - [x] `nft list chain ip nexusguard input` shows all 5 rules after server start
+  - [x] Rules are idempotent (restart doesn't duplicate rules)
+
+  **QA Scenarios**:
+  ```
+  Scenario: INPUT chain rules exist after restart
+    Tool: Bash (ssh + nft)
+    Preconditions: Server rebuilt with new code
+    Steps:
+      1. SSH to server
+      2. docker compose down && docker compose up -d --build
+      3. sleep 5
+      4. nft list chain ip nexusguard input
+    Expected Result: 5 rules visible (estab, icmp, wg_api, wg_tunnel, wg_isolation)
+    Evidence: .sisyphus/evidence/task3-input-rules.txt
+
+  Scenario: Ping from WG peer is dropped
+    Tool: Bash (ssh)
+    Steps:
+      1. SSH to server
+      2. nft list chain ip nexusguard input | grep wg_isolation
+      3. Count packets: nft -a list chain ip nexusguard input | grep wg_isolation
+    Expected Result: Drop rule exists with counter > 0
+    Evidence: .sisyphus/evidence/task3-ping-dropped.txt
+
+  Scenario: Docker networking unaffected
+    Tool: Bash (ssh + curl)
+    Steps:
+      1. curl -s -o /dev/null -w '%{http_code}' http://172.20.8.191:80
+      2. docker ps
+    Expected Result: HTTP 200, containers running

+  ```
+
+  **Commit**: YES
+  - Message: `fix(nftables): add INPUT chain rules for WG peer isolation in InitNetwork`
+  - Files: `internal/firewall/nftables_linux.go`

+  - Build dashboard-ui: `cd apps/dashboard-ui && npm run build`
+  - Commit all changes
+  - Push to remote
+  - SSH to production: `git pull --recurse-submodules && docker compose down && docker compose up -d --build`

+# NexusGuard Config Architecture
+
+## TL;DR
+
+> Unified config system for non-Docker deployment: `/etc/nexusguard/nexusguard.conf` (shell-sourceable), install/uninstall scripts, systemd service, and nginx runtime config injection for dashboard.
+> 
+> **Deliverables**:
+> - Server-core config file loader
+> - Dashboard runtime config via nginx
+> - Install/uninstall shell scripts
+> - Systemd service file
+> - Nginx config template
+> 
+> **Estimated Effort**: Medium
+> **Parallel Execution**: YES - 3 waves
+> **Critical Path**: Config loader → Dashboard changes → Install scripts → Testing
+
+---
+
+## Context
+
+### Original Request
+User wants unified config architecture for non-Docker deployment. Currently config is split:
+- Server-core: env vars from docker-compose `.env`
+- Dashboard: `VITE_API_BASE_URL` baked at build time
+- Device-agent: CLI args (no change needed)
+
+### Interview Summary
+**Key Discussions**:
+- Config format: Shell-sourceable (export KEY=VALUE)
+- Config location: `/etc/nexusguard/nexusguard.conf`
+- Structure: Server-core + dashboard-ui share ONE config file
+- Device-agent: No config file (uses CLI args)
+- Dashboard: Runtime config via nginx template (window.__CONFIG__)
+- Docker: Keep env vars unchanged
+- Non-Docker: Read from nexusguard.conf
+- Install: Shell script (nexusguard-install.sh)
+- Uninstall: Shell script (nexusguard-uninstall.sh)
+- Systemd: Service file for server-core
+
+**Research Findings**:
+- Server-core config loading: `internal/config/config.go` reads env vars via `os.Getenv()`
+- Dashboard config: `src/services/api.ts` uses `import.meta.env.VITE_API_BASE_URL`
+- Existing patterns: Device-agent's `install_agent.sh` and `sys-bridge.service`
+- Real server: 172.20.8.191 for testing
+
+### Metis Review
+**Identified Gaps** (addressed):
+- Config file path should be overridable via `NEXUSGUARD_CONF` env var
+- nginx can't source bash files → use `envsubst` with template
+- Secrets in conf file need `chmod 600` permissions
+- Config loading order: conf file → env vars → defaults
+- Install script must be idempotent
+- Dashboard `window.__CONFIG__` timing: script tag MUST appear before Vue bundle
+- Edge cases: empty values, spaces, special characters, BOM, Windows line endings
+
+---
+
+## Work Objectives
+
+### Core Objective
+Implement unified config system for non-Docker NexusGuard deployment with `/etc/nexusguard/nexusguard.conf`, install/uninstall scripts, and nginx runtime config injection.
+
+### Concrete Deliverables
+- `apps/server-core/internal/config/config_loader.go` - Config file loader
+- `apps/server-core/internal/config/config_test.go` - Unit tests
+- `apps/server-core/main.go` - Updated to call config loader
+- `apps/dashboard-ui/src/services/api.ts` - Runtime config support
+- `apps/dashboard-ui/nginx.conf.template` - Nginx config template
+- `nexusguard-install.sh` - Install script
+- `nexusguard-uninstall.sh` - Uninstall script
+- `apps/server-core/nexusguard-server.service` - Systemd service file
+
+### Definition of Done
+- [ ] Server-core reads config from `/etc/nexusguard/nexusguard.conf`
+- [ ] Dashboard reads runtime config from nginx-injected `window.__CONFIG__`
+- [ ] Install script copies binaries, creates config, sets up systemd, configures nginx
+- [ ] Uninstall script stops service, removes files, reloads nginx
+- [ ] All unit tests pass
+- [ ] Tested on real server (172.20.8.191)
+
+### Must Have
+- Config file loading with fallback to env vars
+- Dashboard runtime config injection via nginx
+- Idempotent install/uninstall scripts
+- Secure config file permissions (chmod 600)
+- Systemd service with restart on failure
+
+### Must NOT Have (Guardrails)
+- **NEVER** modify Docker behavior (docker-compose.yml, Dockerfiles stay unchanged)
+- **NEVER** touch device-agent (uses CLI args, not config file)
+- **NEVER** add PostgreSQL/Redis installation to install script
+- **NEVER** add TLS/HTTPS setup to install script
+- **NEVER** add auto-reload on config changes
+- **NEVER** add config file validation (schema)
+- **NEVER** add log rotation or monitoring
+- **NEVER** add multi-server deployment support
+- **NEVER** add `nexusguard-ctl` management CLI
+
+---
+
+## Verification Strategy
+
+> **ZERO HUMAN INTERVENTION** - ALL verification is agent-executed. No exceptions.
+
+### Test Decision
+- **Infrastructure exists**: YES (Go tests for server-core, npm for dashboard)
+- **Automated tests**: YES (Tests-after)
+- **Framework**: Go testing (server-core), no framework for dashboard (manual verification)
+
+### QA Policy
+Every task MUST include agent-executed QA scenarios.
+Evidence saved to `.sisyphus/evidence/task-{N}-{scenario-slug}.{ext}`.
+
+- **Go code**: Use `go test` - Run tests, assert pass
+- **Shell scripts**: Use `bash` - Run script, verify exit code and file creation
+- **Config loading**: Use Go test with temp files
+- **Nginx config**: Use `nginx -t` to validate syntax
+- **Real server**: SSH to 172.20.8.191 and test

+- [x] 1. Config file loader for server-core
+
+  **What to do**:
+  - Create `apps/server-core/internal/config/config_loader.go`
+  - Implement `LoadConfFile(path string)` function
+  - Parse shell-sourceable format (export KEY=VALUE)
+  - Handle edge cases: comments (#), empty lines, spaces, Windows line endings (\r\n), BOM

+# Real-Time Traffic Monitoring + gRPC + TimescaleDB
+
+## TL;DR
+> Real-time device/node status via SSE + gRPC, traffic monitoring with TimescaleDB, historical charts with daily aggregation, toggle controls for chart display.
+
+**Deliverables**:
+- gRPC streaming for device-agent ↔ server (Rx/Tx data)
+- SSE endpoint for dashboard real-time updates
+- TimescaleDB schema for traffic logging
+- Traffic recorder (Redis → DB batch)
+- Dashboard traffic chart with historical data
+- Toggle to disable real-time display (per device/global)
+
+**Estimated Effort**: Large
+**Parallel Execution**: YES - 4 waves
+**Critical Path**: T1 → T2 → T3 → T4 → T5 → T6
+
+---
+
+## Context
+
+### Original Request
+User wants real-time device/node online status without page refresh, Rx/Tx traffic with charts, daily/historical logging, and toggle controls for chart display. System scales to 1000+ devices.
+
+### Architecture Decision
+- **Device-Agent → Server**: gRPC streaming (bidirectional, efficient for 1000+ connections)
+- **Dashboard ← Server**: SSE (browser native, HTTP friendly, auto-reconnect)
+- **Real-time state**: Redis (fast in-memory, pub/sub)
+- **Traffic recording**: TimescaleDB (PostgreSQL extension, time-series optimized)
+- **Historical query**: TimescaleDB continuous aggregates
+
+### Two Device Types
+1. **Device-Agent**: Custom Go agent, sends Rx/Tx via gRPC stream
+2. **WireGuard Client**: Official WG clients (MikroTik, phone), data from kernel (`wg show`)
+
+---
+
+## Work Objectives
+
+### Core Objective
+Real-time device status + traffic monitoring for 1000+ devices with historical charts.
+
+### Must Have
+- gRPC streaming for agent traffic data
+- SSE for dashboard real-time updates
+- TimescaleDB for traffic logging
+- Traffic chart per device/node
+- Toggle to disable chart display
+- Historical data query (daily/hourly)
+
+### Must NOT Have
+- Do NOT remove existing heartbeat system
+- Do NOT change existing API endpoints
+- Do NOT add external dependencies (Kafka, RabbitMQ)
+- Do NOT use WebSocket (SSE is sufficient for dashboard)
+
+---
+
+## Verification Strategy
+
+### Test Decision
+- **Infrastructure exists**: YES (Go, Vue 3, PostgreSQL)
+- **Automated tests**: Tests-after
+- **Framework**: Go test + npm test
+
+---

+        tx_rate     BIGINT DEFAULT 0
+    );
+    SELECT create_hypertable('device_traffic', 'time');
+    ```
+  - Create daily aggregate view:
+    ```sql
+    CREATE MATERIALIZED VIEW device_traffic_daily
+    WITH (timescaledb.continuous) AS
+    SELECT
+        time_bucket('1 day', time) AS day,
+        device_id,

+
+- [ ] 3. **Traffic recorder (Redis → DB batch)**
+
+  **What to do**:
+  - Create `apps/server-core/internal/traffic/recorder.go`:
+    - `TrafficRecorder` struct with Redis client + TimescaleDB connection
+    - `Record(deviceID, rxBytes, txBytes int64)` - stores to Redis (fast)

+
+  **Acceptance Criteria**:
+  - [ ] `go build` passes
+  - [ ] Agent connects to gRPC server
+  - [ ] Traffic reports sent every 5 seconds
+
+  **Commit**: YES
+  - Message: `feat(agent): add gRPC traffic streaming client`
+  - Files: `apps/device-agent/main.go`, new gRPC client code
+
+- [ ] 8. **Kernel sync enhancement**
+
+  **What to do**:
+  - Enhance `apps/server-core/internal/wgmanager/handshakesync.go`:
+    - Add Rx/Tx bytes collection per peer
+    - Store traffic data to Redis/TimescaleDB
+    - Handle WireGuard client devices (no agent)
+  - Update `GetPeerHandshakes()` to include traffic data
+  - Ensure kernel sync records traffic for all WG clients
+
+  **Must NOT do**:
+  - Do NOT change existing handshake logic
+  - Do NOT break agent devices
+
+  **Recommended Agent Profile**:
+  - **Category**: `quick`
+  - **Skills**: `[]`
+
+  **Parallelization**:
+  - **Can Run In Parallel**: NO (depends on T3)
+  - **Parallel Group**: Wave 3
+  - **Blocks**: None
+  - **Blocked By**: T3
+
+  **References**:
+  - `apps/server-core/internal/wgmanager/handshakesync.go` - existing sync
+
+  **Acceptance Criteria**:
+  - [ ] `go build -tags dev ./...` passes
+  - [ ] Kernel sync records Rx/Tx for WG clients
+
+  **Commit**: YES
+  - Message: `feat(wgmanager): enhance kernel sync with traffic data`
+  - Files: `apps/server-core/internal/wgmanager/handshakesync.go`
+
+- [ ] 9. **Dashboard traffic chart**
+
+  **What to do**:
+  - Create `apps/dashboard-ui/src/components/TrafficChart.vue`:
+    - Line chart for Rx/Tx over time
+    - Use Chart.js or ApexCharts
+    - Real-time updates via SSE
+    - Responsive design
+  - Add chart to `DeviceDetail.vue` (per-device)
+  - Add chart to `Dashboard.vue` (per-node aggregate)
+  - Time range selector (1h, 6h, 24h, 7d, 30d)
+  - Auto-refresh every 5 seconds
+
+  **Must NOT do**:
+  - Do NOT add heavy chart libraries (use lightweight)
+  - Do NOT block UI on chart render
+
+  **Recommended Agent Profile**:
+  - **Category**: `visual-engineering`
+  - **Skills**: `[]`
+
+  **Parallelization**:
+  - **Can Run In Parallel**: YES (with T10, T11)
+  - **Parallel Group**: Wave 4
+  - **Blocks**: None
+  - **Blocked By**: T5, T6
+
+  **References**:
+  - `apps/dashboard-ui/src/views/DeviceDetail.vue` - existing page
+  - Chart.js docs: https://www.chartjs.org/
+
+  **Acceptance Criteria**:
+  - [ ] `npm run build` passes
+  - [ ] Chart displays real-time traffic
+  - [ ] Time range selector works
+
+  **Commit**: YES
+  - Message: `feat(ui): add traffic chart component`
+  - Files: `apps/dashboard-ui/src/components/TrafficChart.vue`, `apps/dashboard-ui/src/views/DeviceDetail.vue`, `apps/dashboard-ui/src/views/Dashboard.vue`
+
+- [ ] 10. **Toggle controls**
+
+  **What to do**:
+  - Add toggle to `DeviceDetail.vue`:
+    - "Real-time Traffic" toggle (per device)
+    - When OFF: chart shows historical only, no live updates
+    - When ON: chart updates in real-time via SSE
+  - Add global toggle to `Dashboard.vue`:
+    - "Disable All Real-time Charts" toggle
+    - Saves preference to localStorage
+  - Backend: SSE still sends data, frontend just ignores if toggle OFF
+  - Traffic recording always active (toggle only affects display)
+
+  **Must NOT do**:
+  - Do NOT stop recording when toggle is OFF
+  - Do NOT add new backend endpoints
+
+  **Recommended Agent Profile**:
+  - **Category**: `visual-engineering`
+  - **Skills**: `[]`
+
+  **Parallelization**:
+  - **Can Run In Parallel**: YES (with T9, T11)
+  - **Parallel Group**: Wave 4
+  - **Blocks**: None
+  - **Blocked By**: T9
+
+  **References**:
+  - `apps/dashboard-ui/src/views/DeviceDetail.vue`
+  - localStorage pattern
+
+  **Acceptance Criteria**:
+  - [ ] `npm run build` passes
+  - [ ] Per-device toggle works
+  - [ ] Global toggle works
+  - [ ] Recording continues when display is OFF
+
+  **Commit**: YES
+  - Message: `feat(ui): add real-time chart toggle controls`
+  - Files: `apps/dashboard-ui/src/components/TrafficChart.vue`, `apps/dashboard-ui/src/views/DeviceDetail.vue`, `apps/dashboard-ui/src/views/Dashboard.vue`
+
+- [ ] 11. **Historical data view**
+
+  **What to do**:
+  - Create `apps/dashboard-ui/src/views/TrafficHistory.vue`:
+    - Full-page traffic history view
+    - Date range picker
+    - Device/node selector
+    - Export to CSV
+    - Daily/hourly aggregation
+  - Add route: `/traffic-history`
+  - Query backend traffic API
+  - Display in table + chart
+
+  **Must NOT do**:
+  - Do NOT allow querying beyond retention period
+  - Do NOT expose raw data (use aggregates only)
+
+  **Recommended Agent Profile**:
+  - **Category**: `visual-engineering`
+  - **Skills**: `[]`
+
+  **Parallelization**:
+  - **Can Run In Parallel**: YES (with T9, T10)
+  - **Parallel Group**: Wave 4
+  - **Blocks**: None
+  - **Blocked By**: T6
+
+  **References**:
+  - `apps/dashboard-ui/src/router/index.ts` - routing
+  - Date picker component
+
+  **Acceptance Criteria**:
+  - [ ] `npm run build` passes
+  - [ ] History page accessible at /traffic-history
+  - [ ] Date range filter works
+  - [ ] Export to CSV works
+
+  **Commit**: YES
+  - Message: `feat(ui): add traffic history view`
+  - Files: `apps/dashboard-ui/src/views/TrafficHistory.vue`, `apps/dashboard-ui/src/router/index.ts`
