-## Workflow Orchestration
-### 1. Plan Node Default
-- Enter plan mode for ANY non-trivial task (3+ steps or architectural decisions)
-- If something goes sideways, STOP and re-plan immediately - don't keep pushing
-- Use plan mode for verification steps, not just building
-- Write detailed specs upfront to reduce ambiguity
-### 2. Subagent Strategy
-- Use subagents liberally to keep main context window clean
-- Offload research, exploration, and parallel analysis to subagents
-- For complex problems, throw more compute at it via subagents
-- One tack per subagent for focused execution
-### 3. Self-Improvement Loop
-- After ANY correction from the user: update 'tasks/lessons.md" with the pattern
-- Write rules for yourself that prevent the same mistake
-- Ruthlessly iterate on these lessons until mistake rate drops
-- Review lessons at session start for relevant project
-### 4. Verification Before Done
-- Never mark a task complete without proving it works
-- Diff behavior between main and your changes when relevant
-- Ask yourself: "Would a staff engineer approve this?"
-- Run tests, check logs, demonstrate correctness
-### 5. Demand Elegance (Balanced)
-- For non-trivial changes: pause and ask "is there a more elegant way?"
-- If a fix feels hacky: "Knowing everything I know now, implement the elegant solution"
-- Skip this for simple, obvious fixes - don't over-engineer
--Challenge your own work before presenting it
-### 6. Autonomous Bug Fizing
-- When given a bug report: just fix it. Don't ask for hand-holding
-- Point at logs, errors, failing tests - then resolve them
-- Zero context switching required from the user
-- Go fix failing CI tests without being told how
-## Task Management
-1. **Plan First**: Write plan to "tasks/todo.md" with checkable items
-2. **Verify Plan**: Check in before starting implementation
-3. **Track Progress**: Mark items complete as you go
-4. **Explain Changes**: High-level summary at each step
-5. **Document Results**: Add review section to 'tasks/todo.md"
-6. **Capture Lessons**: Update 'tasks/lessons.md' after corrections
-## Core Principles
-- **Simplicity First**: Make every change as simple as possible. Impact minimal code.
-- **No Laziness**: Find root causes. No temporary fixes. Senior developer standards.
-- **Minimat Impact**: Changes should only touch what's necessary. Avoid introducing bugs.

+
+## Project Overview
+
+INTERCEPT is a web-based Signal Intelligence (SIGINT) platform providing a unified Flask interface for software-defined radio (SDR) tools. It supports pager decoding, 433MHz sensors, ADS-B aircraft tracking, ACARS messaging, WiFi/Bluetooth scanning, satellite tracking, ISS SSTV decoding, AIS vessel tracking, weather satellite imagery (NOAA APT & Meteor LRPT), and Meshtastic mesh networking.
+
+## Common Commands
+
+### Docker (Primary)
+```bash
+# Build and run (basic profile)
+docker compose --profile basic up -d
+
+# Build and run with ADS-B history (Postgres)
+docker compose --profile history up -d
+
+# Rebuild after code changes
+docker compose --profile basic up -d --build
+
+# Multi-arch build (amd64 + arm64 for RPi)
+./build-multiarch.sh
+```
+
+### Local Setup (Alternative)
+```bash
+# First-time setup (interactive wizard with install profiles)
+./setup.sh
+
+# Or headless full install
+./setup.sh --non-interactive
+
+# Or install specific profiles
+./setup.sh --profile=core,weather
+
+# Run with production server (gunicorn + gevent, handles concurrent SSE/WebSocket)
+sudo ./start.sh
+
+# Or for quick local dev (Flask dev server)
+sudo -E venv/bin/python intercept.py
+
+# Other setup utilities
+./setup.sh --health-check      # Verify installation
+./setup.sh --postgres-setup    # Set up ADS-B history database
+./setup.sh --menu              # Force interactive menu
+```
+
+### Testing
+```bash
+# Run all tests
+pytest
+
+# Run specific test file
+pytest tests/test_bluetooth.py
+
+# Run with coverage
+pytest --cov=routes --cov=utils
+
+# Run a specific test
+pytest tests/test_bluetooth.py::test_function_name -v
+```
+
+### Linting and Formatting
+```bash
+# Lint with ruff
+ruff check .
+
+# Auto-fix linting issues
+ruff check --fix .
+
+# Format with black
+black .
+
+# Type checking
+mypy .
+```
+
+## Architecture
+
+### Entry Points
+- `setup.sh` - Menu-driven installer with profile system (wizard, health check, PostgreSQL setup, env configurator, update, uninstall). Sources `.env` on startup via `start.sh`.
+- `start.sh` - Production startup script (gunicorn + gevent auto-detection, CLI flags, HTTPS, `.env` sourcing, fallback to Flask dev server)
+- `intercept.py` - Direct Flask dev server entry point (quick local development)
+- `app.py` - Flask application initialization, global state management, process lifecycle, SSE streaming infrastructure, conditional gevent monkey-patch
+
+### Route Blueprints (routes/)
+Each signal type has its own Flask blueprint:
+- `pager.py` - POCSAG/FLEX decoding via rtl_fm + multimon-ng
+- `sensor.py` - 433MHz IoT sensors via rtl_433
+- `adsb.py` - Aircraft tracking via dump1090 (SBS protocol on port 30003)
+- `acars.py` - Aircraft datalink messages via acarsdec
+- `wifi.py`, `wifi_v2.py` - WiFi scanning (legacy and unified APIs)
+- `bluetooth.py`, `bluetooth_v2.py` - Bluetooth scanning (legacy and unified APIs)
+- `satellite.py` - Pass prediction using TLE data
+- `sstv.py` - ISS SSTV image decoding via slowrx
+- `weather_sat.py` - NOAA APT & Meteor LRPT via SatDump
+- `ais.py` - AIS vessel tracking and VHF DSC distress monitoring
+- `aprs.py` - Amateur packet radio via direwolf
+- `rtlamr.py` - Utility meter reading
+- `meshtastic_routes.py` - Meshtastic LoRa mesh networking
+
+### Core Utilities (utils/)
+
+**SDR Abstraction Layer** (`utils/sdr/`):
+- `SDRFactory` with factory pattern for multiple SDR types (RTL-SDR, LimeSDR, HackRF, Airspy, SDRPlay)
+- Each type has a `CommandBuilder` for generating CLI commands
+
+**Bluetooth Module** (`utils/bluetooth/`):
+- Multi-backend: DBus/BlueZ primary, fallback for systems without BlueZ
+- `aggregator.py` - Merges observations across time
+- `tracker_signatures.py` - 47K+ known tracker fingerprints (AirTag, Tile, SmartTag)
+- `heuristics.py` - Behavioral analysis for device classification
+
+**TSCM (Counter-Surveillance)** (`utils/tscm/`):
+- `baseline.py` - Snapshot "normal" RF environment
+- `detector.py` - Compare current scan to baseline, flag anomalies
+- `device_identity.py` - Track devices despite MAC randomization
+- `correlation.py` - Cross-reference Bluetooth and WiFi observations
+
+**WiFi Utilities** (`utils/wifi/`):
+- Platform-agnostic scanner with parsers for airodump-ng, nmcli, iw, iwlist, airport (macOS)
+- `channel_analyzer.py` - Frequency band analysis
+
+**Weather Satellite** (`utils/weather_sat.py`):
+- Singleton `WeatherSatDecoder` using SatDump CLI for NOAA APT and Meteor LRPT
+- Subprocess management with stdout parsing, image watcher via rglob
+- Pass prediction using skyfield TLE data
+
+**SSTV Decoder** (`utils/sstv.py`):
+- ISS SSTV reception via slowrx with Doppler tracking
+- Singleton pattern, image gallery with timestamped filenames
+
+### Key Patterns
+
+**Server-Sent Events (SSE)**: All real-time features stream via SSE endpoints (`/stream_pager`, `/stream_sensor`, etc.). Pattern uses `queue.Queue` with timeout and keepalive messages. Under gunicorn + gevent, each SSE connection is a lightweight greenlet instead of an OS thread.
+
+**Process Management**: External decoders run as subprocesses with output threads feeding queues. Use `safe_terminate()` for cleanup. Global locks prevent race conditions.
+
+**Data Stores**: `DataStore` class with TTL-based automatic cleanup (WiFi: 10min, Bluetooth: 5min, Aircraft: 5min).
+
+**Input Validation**: Centralized in `utils/validation.py` - always validate frequencies, gains, device indices before spawning processes.
+
+### External Tool Integrations
+
+| Tool | Purpose | Integration |
+|------|---------|-------------|
+| rtl_fm | FM demodulation | Subprocess, pipes to multimon-ng |
+| multimon-ng | Pager decoding | Reads from rtl_fm stdout |
+| rtl_433 | 433MHz sensors | JSON output parsing |
+| dump1090 | ADS-B decoding | SBS protocol socket (port 30003) |
+| acarsdec | ACARS messages | Output parsing |
+| airmon-ng/airodump-ng | WiFi scanning | Monitor mode, CSV parsing |
+| bluetoothctl/hcitool | Bluetooth | Fallback when DBus unavailable |
+| slowrx | SSTV decoding | Subprocess with audio pipe |
+| SatDump | Weather satellites | CLI live mode, NOAA APT + Meteor LRPT |
+| AIS-catcher | AIS vessel tracking | JSON output parsing |
+| direwolf | APRS | TNC modem for packet radio |
+
+### Frontend Structure
+- **Templates**: `templates/index.html` (main SPA), `templates/partials/modes/*.html` (sidebar panels), `templates/partials/nav.html` (global nav)
+- **JS Modules**: `static/js/modes/*.js` - IIFE pattern per mode (e.g., `WeatherSat`, `SSTV`, `Meshtastic`)
+- **CSS**: `static/css/modes/*.css` - scoped styles per mode, CSS variables for theming (`--bg-card`, `--accent-cyan`, `--font-mono`)
+- **Mode Integration**: Each mode needs entries in `index.html` at ~12 points: CSS include, welcome card, partial include, visuals container, JS include, `validModes` set, `modeGroups` map, classList toggle, `modeNames`, visuals display toggle, titles, and init call in `switchMode()`
+
+### Docker
+- `Dockerfile` - Single-stage build with all SDR tools compiled from source (dump1090, AIS-catcher, slowrx, SatDump, etc.). CMD runs `start.sh` (gunicorn + gevent)
+- `docker-compose.yml` - Two profiles: `basic` (standalone) and `history` (with Postgres for ADS-B)
+- `build-multiarch.sh` - Multi-arch build script for amd64 + arm64 (RPi5)
+- Data persisted via `./data:/app/data` volume mount
+
+### Configuration
+- `config.py` - Environment variable support with `INTERCEPT_` prefix (e.g., `INTERCEPT_PORT`, `INTERCEPT_WEATHER_SAT_GAIN`)
+- Database: SQLite in `instance/` directory for settings, baselines, history
+
+## Testing Notes
+
+Tests use pytest with extensive mocking of external tools. Key fixtures in `tests/conftest.py`. Mock subprocess calls when testing decoder integration.

 All notable changes to iNTERCEPT will be documented in this file.
 
+## [2.27.0] - 2026-05-20
+
+### Fixed
+- **Two-window hang** — Opening the app in two browser tabs/windows caused it to become completely unresponsive. Root cause: HTTP/1.1 limits browsers to 6 connections per origin (shared across all tabs). VoiceAlerts was automatically opening 3 SSE streams per window on page load, so two windows produced 8 persistent connections and permanently blocked all regular HTTP requests. VoiceAlerts streams are now opt-in (disabled by default); users can enable them in settings.
+- **Alert messages split between windows** — The `/alerts/stream` SSE endpoint read from a single queue, so two windows would each receive only half the alerts. Now uses `sse_stream_fanout` so every window gets every alert.
+- **Bluetooth v2 stream split between windows** — Same single-queue issue in `/api/bluetooth/stream`. Fixed with fanout via `subscribe_fanout_queue`, preserving named SSE events (`device_update`, `scan_started`, etc.).
+- **ICAO lookup cache unbounded growth** — `_looked_up_icaos` set was never evicted; capped at 50 000 entries with LRU eviction to prevent memory growth under sustained ADS-B load.
+- **Concurrent ICAO clear race** — `popitem()` on the ICAO dict could raise `RuntimeError` if a clear happened concurrently; guarded with try/except.
+- **Bluetooth tracker fingerprint stability** — Tracker signature scan was incorrectly resetting stability counters on unchanged payloads; now skips the scan when the BLE payload fingerprint is unchanged.
+
+### Added
+- **UI Tier system** — Three display modes selectable from the nav bar: *Lean* (minimal, no decorative elements), *Standard* (default), and *Enhanced* (full animations and ambient effects). Replaces the old animations toggle.
+- **Display mode in first-run setup** — The first-run modal now includes a display mode selection step so new users can pick their preferred visual style during initial setup.
+
+### Performance
+- ADS-B SSE snapshot priming moved inside the response generator (avoids blocking before headers are sent).
+- WiFi network filter combined into a single list pass instead of chained filters.
+- Bluetooth tracker signature scan skips processing when the BLE payload fingerprint is unchanged.
+- `DataStore` cleanup minimises lock hold time by collecting expired keys before acquiring the write lock.
+
+---
+
+## [2.26.11] - 2026-03-14
+
+### Fixed
+- **APRS map ignores configured observer position** — The APRS map always fell back to the centre of the US (39.8°N, 98.6°W) when no live GPS fix was available, ignoring the observer position configured in `.env` (`INTERCEPT_DEFAULT_LAT` / `INTERCEPT_DEFAULT_LON`). Now seeds the APRS user location from the shared observer location on page load, so the map centres correctly and distance calculations work. (#193)
+
+---
+
+## [2.26.10] - 2026-03-14
+
+### Fixed
+- **APRS stop timeout and inverted SDR device status** — The APRS stop endpoint terminated two processes sequentially (up to 4s) while the frontend timed out at 2.2s, causing console errors and the SDR status panel to show stale state (active after stop, idle during use). Now releases the SDR device immediately and terminates processes in a background thread so the response returns instantly. (#194)
+
+---
+
+## [2.26.9] - 2026-03-14
+
+### Fixed
+- **ADS-B bias-t support for RTL-SDR Blog V4** — When dump1090 lacks native `--enable-biast` support, the system now falls back to `rtl_biast` (from RTL-SDR Blog drivers) to enable bias-t power before starting dump1090. The Blog V4's built-in LNA requires bias-t to receive ADS-B signals. (#195)
+
+---
+
+## [2.26.8] - 2026-03-14
+
+### Fixed
+- **acarsdec build failure on macOS** — `HOST_NAME_MAX` is Linux-specific (`<limits.h>`) and undefined on macOS, causing 3 compile errors in `acarsdec.c`. Now patched with `#define HOST_NAME_MAX 255` before building. Also fixed deprecated `-Ofast` flag warning on all macOS architectures (was only patched for arm64). (#187)
+
+---
+
+## [2.26.7] - 2026-03-14
+
+### Fixed
+- **Health check SDR detection on macOS** — `timeout` (GNU coreutils) is not available on macOS, causing `rtl_test` to silently fail and report "No RTL-SDR device found" even when one is connected. Now tries `timeout`, then `gtimeout` (Homebrew coreutils), then falls back to a background process with manual kill. (#188)
+
+---
+
+## [2.26.6] - 2026-03-14
+
+### Fixed
+- **Oversized branded 'i' logo on dashboards** — `.logo span { display: inline }` in dashboard CSS had higher specificity (0,1,1) than `.brand-i { display: inline-block }` (0,1,0), forcing the branded "i" SVG to render as inline which ignores width/height. Added `.logo .brand-i` selector (0,2,0) to retain `inline-block` display. (#189)
+
+---
+
+## [2.26.5] - 2026-03-14
+
+### Fixed
+- **Database errors crash entire UI** — `get_setting()` now catches `sqlite3.OperationalError` and returns the default value instead of propagating the exception. Previously, if the database was inaccessible (e.g. root-owned `instance/` directory from running with `sudo`), the `inject_offline_settings` context processor would crash every page render with a 500 Internal Server Error. (#190)
+
+---
+
+## [2.26.4] - 2026-03-14
+
+### Fixed
+- **Environment Configurator crash** — `read_env_var()` crashed with "Setup failed at line 2333" when `.env` existed but didn't contain the variable being looked up. `grep` returned exit code 1 (no match), which `pipefail` propagated and `set -e` turned into a fatal error. Fixed by appending `|| true` to the pipeline. (#191)
+
+---
+
+## [2.26.3] - 2026-03-13
+
+### Fixed
+- **SatDump AVX2 crash** — SatDump now compiles with `-march=x86-64` on x86_64 platforms (Docker and `setup.sh`), preventing "Illegal instruction" crashes on CPUs without AVX2. SIMD plugins still use runtime detection for acceleration on capable hardware. (#185)
+
+---
+
+## [2.26.2] - 2026-03-13
+
+### Fixed
+- **Docker startup crash** — `.dockerignore` excluded the entire `data/` directory, which is now a Python package (`data.oui`, `data.patterns`, `data.satellites`). Caused `ModuleNotFoundError: No module named 'data.oui'` on container startup. Fixed by only excluding non-code files from `data/`.
+
+---
+
+## [2.26.1] - 2026-03-13
+
+### Fixed
+- **Default admin credentials** — Default `ADMIN_PASSWORD` changed from empty string to `admin`, matching the README documentation (`admin:admin`)
+- **Config credential sync** — Admin password changes in `config.py` or via `INTERCEPT_ADMIN_PASSWORD` env var now sync to the database on restart, without needing to delete the DB
+
+---
+
+## [2.26.0] - 2026-03-13
+
+### Fixed
+- **SSE fanout crash** - `_run_fanout` daemon thread no longer crashes with `AttributeError: 'NoneType' object has no attribute 'get'` when source queue becomes None during interpreter shutdown
+- **Branded logo FOUC** - Added inline `width`/`height` to branded "i" SVG elements across 10 templates to prevent oversized rendering before CSS loads; refresh no longer needed
+
+---
+
+## [2.25.0] - 2026-03-12
+
+### Added
+- **SSEManager** - Centralized SSE connection management with exponential backoff reconnection and visual connection status indicator
+- **Loading button states** - `withLoadingButton()` utility for async action buttons across all modes
+- **Actionable error reporting** - `reportActionableError()` added to 5 mode JS files for user-friendly error messages
+- **Destructive action confirmation modals** - Custom modal system replacing 25 native `confirm()` calls
+
+### Changed
+- **Accessibility improvements** - aria-labels on interactive elements, form label associations, keyboard-navigable lists
+- **CSS variable adoption** - Replaced hardcoded hex colors with CSS custom properties across 16+ files
+- **Inline style extraction** - `classList.toggle()` replaces inline `display` manipulation throughout codebase
+- **Merged `global-nav.css` into `layout.css`** - Consolidated navigation styles
+- **Reduced `!important` usage** - Responsive.css `!important` count reduced from 71 to 8
+- **Standardized breakpoints** - Unified to 480/768/1024/1280px across all responsive styles
+- **Mobile UX polish** - Improved touch targets, code overflow handling, and responsive layouts
+
+### Fixed
+- Deep-linked mode scripts now wait for body parse before executing, preventing initialization failures

+## Drone Intelligence
+
+Multi-vector UAV detection and identification system combining three complementary detection methods into unified contact tracking.
+
+### Detection Vectors
+
+- **Remote ID (WiFi/BLE)** — Parses ASTM F3411-22a broadcast frames from WiFi Beacon and BLE Advertisement packets. Extracts drone ID, operator ID, drone type, GPS position, altitude, speed, and emergency status. Mandatory for all drones >250g in the US/EU since 2023.
+- **RTL-SDR RF (433/868 MHz)** — Monitors ISM bands for control link and telemetry signals characteristic of consumer and FPV drones. Detects DJI OcuSync, FrSky, FlySky, and generic FSK/GFSK drone control protocols.
+- **HackRF (2.4/5.8 GHz)** — Wide-scan of video downlink and telemetry bands used by most consumer drones. Detects power above noise floor across 2.400–2.483 GHz and 5.725–5.875 GHz ISM bands.
+
+### Contact Correlation
+
+The `DroneCorrelator` merges raw observations from all three vectors into unified `DroneContact` objects:
+- **TTL-based store** — contacts expire after 120 seconds of no activity
+- **Multi-vector fusion** — a single contact can be seen on 1–3 vectors simultaneously
+- **Deduplication** — observations from the same vector within 5 seconds are collapsed
+
+### Risk Scoring
+
+| Level | Criteria |
+|-------|----------|
+| High | No Remote ID broadcast (non-compliant) or ASTM non-conformant frame |
+| Medium | Multiple detection vectors active, or RSSI delta >15 dB between vectors |
+| Low | Compliant Remote ID present, single detection vector |
+
+### Live Map
+
+Remote ID contacts with GPS position data are plotted on a Leaflet map. Markers show drone ID and last known coordinates. Map updates in real time via SSE.
+
+### Requirements
+
+- WiFi adapter capable of monitor mode (for BLE/WiFi Remote ID)
+- RTL-SDR dongle (for 433/868 MHz RF detection)
+- HackRF One (optional, for 2.4/5.8 GHz detection)
+- Python package: `opendroneid>=1.0`

+1. **Open Mode** - Select "Drone Intel" from the Intel group in the navigation bar
+2. **Configure Interfaces** - Enter your WiFi interface name (must support monitor mode) for Remote ID detection
+3. **Set RTL-SDR Index** - If you have multiple RTL-SDR devices, enter the device index (default: 0)
+4. **Start** - Click "Start Scan" to activate all available detection vectors simultaneously
+5. **Monitor Contacts** - Detected drone contacts appear in the contact list with ID, vectors, risk level, and last seen time
+6. **View Map** - Contacts with GPS data from Remote ID are plotted on the live map
+
+### Detection Vectors
+
+- **Remote ID (WiFi/BLE)** — Passive sniff of 802.11 beacon frames and BLE advertisements. Decodes ASTM F3411 payloads: drone GPS, operator ID, drone type, speed, altitude, and emergency status
+- **433/868 MHz RF** — RTL-SDR scans ISM bands for drone control link and telemetry RF signatures
+- **2.4/5.8 GHz** — HackRF (if present) sweeps video downlink bands for active drone transmissions
+
+### Risk Levels
+
+- **High** — Drone operating without Remote ID (non-compliant) or malformed ASTM frame. Warrants immediate attention.
+- **Medium** — Contact detected on multiple RF vectors, or significant RSSI difference between vectors (>15 dB). May indicate evasion or multi-radio platform.
+- **Low** — Compliant Remote ID broadcast, single detection vector. Standard consumer drone.
+
+### Tips
+
+- Remote ID is mandatory for drones >250g in the US (FAA) and EU (EU 2019/945) — absence of Remote ID is itself a significant indicator
+- WiFi adapter must support monitor mode; run `airmon-ng check kill` if other processes interfere
+- The contact map only shows drones that broadcast GPS coordinates via Remote ID
+- Contacts expire after 120 seconds of inactivity — the list shows only currently active drones
+- HackRF detection is passive (receive-only); no transmission occurs

+## Webhooks & Notifications
+
+INTERCEPT has a built-in alert engine that fires webhooks when decoded events match configurable rules. This lets you forward pager messages (or events from any other mode) to Discord, Slack, n8n, Home Assistant, or any HTTP endpoint.
+
+### How it works
+
+1. You configure **alert rules** via the Alerts UI — each rule defines which mode and event type to watch, optional match criteria, and a severity level.
+2. When an incoming event matches a rule, INTERCEPT stores it in the alert log and POSTs a JSON payload to your configured webhook URL.
+3. All modes are supported: pager, sensor, ADS-B, AIS, ACARS, WiFi, Bluetooth, and more.
+
+### Enable the webhook
+
+Set these environment variables in your `.env` file or `docker-compose.yml`:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `ALERT_WEBHOOK_URL` | _(empty)_ | URL to POST alert payloads to |
+| `ALERT_WEBHOOK_SECRET` | _(empty)_ | Optional token sent as `X-Alert-Token` header |
+| `ALERT_WEBHOOK_TIMEOUT` | `5` | HTTP timeout in seconds |
+
+**Local install (`.env`):**
+```env
+ALERT_WEBHOOK_URL=https://your-endpoint.example.com/intercept-alerts
+ALERT_WEBHOOK_SECRET=mysecrettoken
+```
+
+**Docker (`.env` or `docker-compose.yml` environment block):**

+### Create an alert rule
+
+1. Open the **Alerts** panel in INTERCEPT
+2. Click **New Rule**
+3. Configure:
+   - **Mode**: `pager` (or any other mode, or leave blank to match all)
+   - **Event type**: `message` for pager decodes (or blank to match all event types)
+   - **Match criteria**: leave empty to forward everything, or add filters (e.g. capcode equals `1234567`, or message contains `FIRE`)
+   - **Severity**: `low`, `medium`, or `high`
+4. Save and enable the rule
+
+### Webhook payload format
+
+INTERCEPT sends a POST request with `Content-Type: application/json`:
+
+```json
+{
+  "id": 42,
+  "rule_id": 1,
+  "mode": "pager",
+  "event_type": "message",
+  "severity": "medium",
+  "title": "My Pager Rule",
+  "message": "message | 1234567",
+  "created_at": "2026-04-13T10:00:00+00:00",
+  "payload": {
+    "mode": "pager",
+    "event_type": "message",
+    "event": {
+      "capcode": "1234567",
+      "message": "UNIT 4 RESPOND TO 123 MAIN ST",
+      "type": "POCSAG1200"
+    },
+    "rule": { "id": 1, "name": "My Pager Rule" }
+  }
+}
+```
+
+### Sending to Discord
+
+Discord webhooks expect a specific JSON format (`content`, `embeds`), so you need a small relay between INTERCEPT and Discord. Two options:
+
+**Option A — No-code relay (recommended)**
+
+Use [n8n](https://n8n.io), [Make](https://make.com), or [Pipedream](https://pipedream.com) to receive INTERCEPT's webhook and forward it to Discord with a custom message template. Point `ALERT_WEBHOOK_URL` at your workflow's ingest URL.
+
+**Option B — Self-hosted Python relay**
+
+Save this as `discord_relay.py` and run it alongside INTERCEPT:
+
+```python
+from flask import Flask, request
+import urllib.request, json
+
+app = Flask(__name__)
+
+DISCORD_WEBHOOK_URL = "https://discord.com/api/webhooks/YOUR_ID/YOUR_TOKEN"
+
+@app.post("/relay")
+def relay():
+    data = request.get_json(force=True)
+    mode = data.get("mode", "unknown").upper()
+    title = data.get("title", "Alert")
+    message = data.get("message", "")
+    event = data.get("payload", {}).get("event", {})
+
+    # Build a readable Discord message
+    lines = [f"**[{mode}]** {title}", message]
+    if event.get("capcode"):
+        lines.append(f"Capcode: `{event['capcode']}`")
+    if event.get("type"):
+        lines.append(f"Protocol: {event['type']}")
+
+    payload = json.dumps({"content": "\n".join(lines)}).encode()
+    req = urllib.request.Request(
+        DISCORD_WEBHOOK_URL,
+        data=payload,
+        headers={"Content-Type": "application/json"},
+        method="POST",
+    )
+    urllib.request.urlopen(req, timeout=5)
+    return "", 204
+
+app.run(host="0.0.0.0", port=5051)
+```
+
+Then set:
+```env
+ALERT_WEBHOOK_URL=http://localhost:5051/relay
+```
+
+Run the relay: `python3 discord_relay.py`
+
+The relay formats pager decodes as Discord messages like:
+
+```
+[PAGER] My Pager Rule
+message | 1234567
+Capcode: `1234567`
+Protocol: POCSAG1200
+```
+
+### Filtering specific capcodes
+
+To only forward decodes from a specific capcode, set the rule's **Match criteria**:
+
+| Field | Operator | Value |
+|-------|----------|-------|
+| `capcode` | equals | `1234567` |
+
+Multiple rules can coexist — e.g. one rule for all pager traffic to a general Discord channel, and a second rule for emergency capcodes with `high` severity to a separate channel (using a second relay instance on a different port).
+
 ## Configuration
 
 INTERCEPT can be configured via environment variables:

+# Meshcore Support — Design Spec
+
+**Date:** 2026-05-10  
+**Status:** Approved
+
+## Overview
+
+Add a Meshcore mode to Intercept, providing full feature parity with the existing Meshtastic module. Meshcore is a LoRa mesh radio platform using a repeater-based routing model (dedicated infrastructure nodes relay; clients do not). It has an official Python library (`meshcore`, PyPI) and a published companion protocol.
+
+## Decisions
+
+| Decision | Choice | Rationale |
+|---|---|---|
+| Connection methods | USB serial + TCP + BLE | Maximum hardware flexibility |
+| Feature scope | Full parity with Meshtastic | Messages, node map, telemetry, traceroute, repeater management |
+| Async integration | Background asyncio thread | meshcore library is asyncio-based; this isolates it cleanly from Flask/gevent |
+| UI layout | Messages-first (mirror Meshtastic) | Sidebar: contacts/nodes. Center: message feed. Tabs: map, telemetry, repeaters |
+| BLE in Docker | Document limitation + proxy workaround | BLE unavailable in containers; meshcore-proxy bridges BLE → TCP |
+
+## Architecture
+
+### New Files
+
+```
+utils/meshcore.py              # MeshcoreClient singleton + dataclasses
+utils/meshcore_client.py       # Thin async wrapper around meshcore library (lives in asyncio thread)
+routes/meshcore.py             # Flask blueprint (/meshcore)
+static/js/modes/meshcore.js    # Frontend IIFE module
+static/css/modes/meshcore.css  # Scoped styles
+templates/partials/modes/meshcore.html  # Sidebar partial
+tests/test_meshcore_client.py
+tests/test_meshcore_routes.py
+tests/test_meshcore_integration.py
+```
+
+### Modified Files
+
+- `routes/__init__.py` — import + `register_blueprint(meshcore_bp)`
+- `templates/index.html` — ~12 insertion points (CSS, partial, JS, validModes, modeGroups, etc.)
+- `requirements.txt` — add `meshcore>=1.0.0` (optional dep, graceful fallback if absent)
+- `.gitignore` — already has `.superpowers/` ✓
+
+### Async Bridge Pattern
+
+```
+meshcore library (asyncio event loop in daemon OS thread)
+  → event callbacks (_on_message, _on_node_update, _on_telemetry)
+  → asyncio.run_coroutine_threadsafe() → queue.Queue (thread-safe, max 500)
+  → /meshcore/stream SSE generator drains queue (30s keepalive timeout)
+  → Frontend EventSource routes by event type
+```
+
+This is the same conceptual pattern as all other decoder integrations in Intercept (ADS-B socket reader, AIS-catcher output thread, rtl_433 stdout thread), just with an explicit asyncio loop instead of a subprocess thread.
+
+## Data Model
+
+```python
+@dataclass
+class MeshcoreMessage:
+    id: str
+    sender_id: str
+    recipient_id: str       # node ID or broadcast address
+    text: str
+    timestamp: datetime
+    hop_count: int
+    snr: float | None
+    is_direct: bool         # DM vs broadcast
+    pending: bool = False   # optimistic send state
+
+@dataclass
+class MeshcoreNode:
+    node_id: str
+    name: str
+    is_repeater: bool       # key Meshcore distinction — rendered differently on map
+    lat: float | None
+    lon: float | None
+    battery_pct: int | None
+    last_seen: datetime
+    snr: float | None
+    hops_away: int | None
+
+@dataclass
+class MeshcoreContact:
+    node_id: str
+    name: str
+    public_key: str         # Meshcore uses key-based addressing
+    last_msg: datetime | None
+
+@dataclass
+class MeshcoreTelemetry:
+    node_id: str
+    timestamp: datetime
+    battery_pct: int | None
+    voltage: float | None
+    temperature: float | None
+    humidity: float | None
+    uptime_secs: int | None
+
+@dataclass
+class MeshcoreTraceroute:
+    origin_id: str
+    destination_id: str
+    hops: list[str]
+    snr_per_hop: list[float]
+    timestamp: datetime
+
+@dataclass
+class SerialConfig:
+    port: str | None = None   # None = auto-discover
+    baud: int = 115200
+
+@dataclass
+class TCPConfig:
+    host: str = "localhost"
+    port: int = 5000          # meshcore-proxy default
+
+@dataclass
+class BLEConfig:
+    device_address: str | None = None  # None = scan for first Meshcore device
+
+ConnectionConfig = SerialConfig | TCPConfig | BLEConfig
+```
+
+Connection state enum: `DISCONNECTED | CONNECTING | CONNECTED | ERROR`
+
+## Connection Handling
+
+### Serial
+Auto-discover: scan `/dev/ttyUSB*`, `/dev/ttyACM*`, `/dev/cu.usbserial*` and return list to frontend via `GET /meshcore/ports`. User can also specify path directly.
+
+### TCP
+Direct connection to `host:port`. Primary use case: meshcore-proxy running on the host, exposing a local USB or BLE device over TCP for Docker deployments.
+
+### BLE
+- Linux/RPi: meshcore library uses BlueZ (requires `bluetoothctl` accessible)
+- macOS: meshcore library uses CoreBluetooth
+- Docker: detect via presence of `/.dockerenv` or `INTERCEPT_DOCKER=1` env var; connect attempt fails fast with clear error directing user to meshcore-proxy
+
+`GET /meshcore/ble/scan` returns: `[{"address": "AA:BB:CC:DD:EE:FF", "name": "MeshCore-Node1", "rssi": -72}]`
+
+### Reconnect
+Exponential backoff: 3 retries at 5s, 15s, 45s (cap 60s). On final failure, pushes `status` SSE event with `state: "error"`. User can manually retry via `POST /meshcore/connect`.
+
+## API Endpoints
+
+| Method | Path | Description |
+|---|---|---|
+| GET | /meshcore/status | Connection state + transport info |
+| POST | /meshcore/connect | Connect with SerialConfig, TCPConfig, or BLEConfig |
+| POST | /meshcore/disconnect | Disconnect and stop background thread |
+| GET | /meshcore/ports | List available serial ports |
+| GET | /meshcore/ble/scan | Scan for nearby Meshcore BLE devices |
+| GET | /meshcore/stream | SSE stream (messages, nodes, telemetry, status) |
+| GET | /meshcore/messages | Recent messages (last 500) |
+| POST | /meshcore/send | Send text message |
+| GET | /meshcore/nodes | All known nodes |
+| GET | /meshcore/contacts | Contact list |
+| POST | /meshcore/contacts | Add contact |
+| DELETE | /meshcore/contacts/`<id>` | Remove contact |
+| GET | /meshcore/telemetry/`<node_id>` | Telemetry history for node |
+| POST | /meshcore/traceroute | Request traceroute to node |
+| GET | /meshcore/repeaters | List repeater nodes |
+
+## SSE Event Format
+
+```json
+{"type": "message",    "data": { ...MeshcoreMessage }}
+{"type": "node",       "data": { ...MeshcoreNode }}
+{"type": "telemetry",  "data": { ...MeshcoreTelemetry }}
+{"type": "traceroute", "data": { ...MeshcoreTraceroute }}
+{"type": "status",     "data": {"state": "connected", "transport": "serial", "device": "/dev/ttyUSB0"}}
+```
+
+Keepalive comment (`: keepalive`) sent every 30 seconds on idle.
+
+## Frontend (meshcore.js)
+
+IIFE pattern, same as all other Intercept JS modules. Key responsibilities:
+
+- **SSE consumer** — `EventSource('/meshcore/stream')`, routes events by `type`
+- **Message feed** — append to scrolling list, optimistic pending state on send
+- **Sidebar** — contact list + node list; repeaters shown separately with triangle icon (vs circle for client nodes), matching Meshcore UI conventions
+- **Tabs** — Map (Leaflet, reuse existing map setup pattern), Telemetry (Chart.js, reuse existing chart helpers), Repeaters (dedicated table view)
+- **Connection panel** — transport selector (Serial / TCP / BLE), port/IP/address input, connect/disconnect button
+- **Traceroute modal** — hop diagram with SNR annotations, same visual style as Meshtastic traceroute
+
+## Repeater Management
+
+Meshcore repeaters are a first-class concept (unlike Meshtastic where all nodes relay). Design:
+
+- Repeaters identified by `is_repeater: true` on `MeshcoreNode`
+- Rendered on map as orange triangles (client nodes = blue circles)
+- Dedicated "Repeaters" tab in the main panel showing: name, location, uptime, last seen, hop count
+- Repeater stats surfaced in telemetry if available (uptime_secs from `MeshcoreTelemetry`)
+
+## Error Handling
+
+- meshcore library not installed → mode loads but shows "meshcore package required: `pip install meshcore`"
+- BLE in Docker → clear error: "BLE unavailable in Docker. Run meshcore-proxy on the host and connect via TCP."
+- Serial port not found → return available ports list in error response
+- Connection lost mid-session → automatic reconnect with backoff; SSE `status` event updates UI indicator
+- Send failure → SSE event clears pending state, shows error in message feed
+
+## Testing
+
+**`tests/test_meshcore_client.py`**
+- Connection state machine transitions
+- Reconnect backoff timing (mock asyncio loop)
+- Message parsing and queue feeding
+- Node/contact TTL expiry
+- BLE unavailability error (Docker scenario)
+
+**`tests/test_meshcore_routes.py`**
+- All REST endpoints: correct JSON shape, status codes
+- `/meshcore/connect` with each connection config type
+- `/meshcore/send` with missing/invalid params → 400
+- SSE stream yields keepalive on empty queue
+- Input validation via `utils/validation.py`
+
+**`tests/test_meshcore_integration.py`**
+- Mock meshcore library at boundary (same approach as mocking meshtastic SDK)
+- Full round-trip: connect → receive message event → appears in SSE stream
+- Traceroute request → hop structure correctly parsed
+
+## Dependencies
+
+```
+meshcore>=1.0.0   # optional — graceful degradation if absent
+```
+
+No new frontend dependencies — Leaflet and Chart.js already present.
