Fixes #1105. Polish follow-ups from #1104's independent review (https://github.com/Kpa-clawbot/CoreScope/pull/1104#issuecomment-4381850096). All 9 MINORs addressed. ## Hardening (`public/app.js`, commitfa58cb6) 1. **`GUTTER = 24` magic constant** → live `getComputedStyle(navLeft).columnGap` read. The "matches `--space-lg`" assertion now lives in CSS, not a stale JS literal. 2. **`fits()` conflated two distinct gaps** → reads `.nav-left`'s gap (between brand/links/more/right cells) and `.nav-links`'s gap (between link items) separately. Today both are `--space-lg=24px`, but a future divergence won't silently miscompute fit. 3. **Implicit 1101px media-query flip dependency** → comment added explaining that `.nav-stats` toggles `display:none ↔ flex` at the boundary, and the rAF-debounced resize handler runs *after* the layout flip so `navRightEl.scrollWidth` reflects the post-flip value. 4. **Outer null-guard widened** → now also covers `linksContainer`, `navRightEl`, `navLeft`, `navTop`. Belt-and-braces. 5. **Cloned link listener parity** → More-menu clones now also get `closeNav()` in addition to `closeMoreMenu()`, matching the listener inline links get at hamburger init. Clicks from the More menu now collapse the hamburger panel just like inline link clicks. 6. **`overflowQueue` ordering** → comment added documenting the `data-priority="high"` signal + reverse construction; explicit numeric-priority migration path noted. 7. **`moreW` hard-coded `70` fallback** → now caches the live measured width the first time the More button is rendered visible; `MORE_BTN_RESERVE_PX = 70` only used as the conservative initial guess until that capture happens. ## Tests (`test-nav-priority-1102-e2e.js`, commit5e9872c) 8. **Identity, not cardinality** (MINOR 7): at 1080/800px the test asserts the visible set is EXACTLY `[#/home, #/packets, #/map, #/live, #/nodes]`. A buggy queue that hid Home and showed Lab would still pass `visibleCount >= 5` — that's no longer enough. 9. **Active-mirroring** (MINOR 9): new case navigates to `#/observers` at 1080px (a route whose link overflows into the More menu) and asserts the inline link is overflowed, the More-menu clone has `.active`, and `#navMoreBtn` has `.active`. Exercises `rebuildMoreMenu`'s active-mirroring path, which depends on `applyNavPriority` running on `hashchange` after the route handler. 10. **CI hookup** (MINOR 8): `deploy.yml` now runs `test-nav-priority-1102-e2e.js` with `CHROMIUM_REQUIRE=1`, so a Chromium provisioning regression fails the build instead of silently SKIPing (matching the existing `test-nav-fluid-1055-e2e.js` invocation). ## Why no red-then-green Per AGENTS.md TDD section: hardening commit is a pure code-quality/null-guard refactor — existing tests stay green and unaltered (the loose `visibleCount >=` assertions still pass against the new code). Test-improvement commit tightens assertions for behaviour that already works (high-priority pinning, active-mirroring); there's no production change to gate. Both branches of "exempt from red→green" are documented in the commit messages. ## E2E / browser validation Test runs against the Go server fixture (`-port 13581 -db test-fixtures/e2e-fixture.db`). All 5 cases (4 viewport cases + new active-mirror case) expected to pass; CI will run them with `CHROMIUM_REQUIRE=1` so any Chromium provisioning regression hard-fails. --------- Co-authored-by: openclaw-bot <bot@openclaw.local>
CoreScope
High-performance mesh network analyzer powered by Go. Sub-millisecond packet queries, ~300 MB memory for 56K+ packets, real-time WebSocket broadcast, full channel decryption.
Self-hosted, open-source MeshCore packet analyzer. Collects MeshCore packets via MQTT, decodes them in real time, and presents a full web UI with live packet feed, interactive maps, channel chat, packet tracing, and per-node analytics.
⚡ Performance
The Go backend serves all 40+ API endpoints from an in-memory packet store with 5 indexes (hash, txID, obsID, observer, node). SQLite is for persistence only — reads never touch disk.
| Metric | Value |
|---|---|
| Packet queries | < 1 ms (in-memory) |
| All API endpoints | < 100 ms |
| Memory (56K packets) | ~300 MB (vs 1.3 GB on Node.js) |
| WebSocket broadcast | Real-time to all connected browsers |
| Channel decryption | AES-128-ECB with rainbow table |
See PERFORMANCE.md for full benchmarks.
✨ Features
📡 Live Trace Map
Real-time animated map with packet route visualization, VCR-style playback controls, and a retro LCD clock. Replay the last 24 hours of mesh activity, scrub through the timeline, or watch packets flow live at up to 4× speed.

🗺️ Network Overview
At-a-glance mesh stats — node counts, packet volume, observer coverage.
📊 Node Analytics
Per-node deep dive with interactive charts: activity timeline, packet type breakdown, SNR distribution, hop count analysis, peer network graph, and hourly heatmap.
💬 Channel Chat
Decoded group messages with sender names, @mentions, timestamps — like reading a Discord channel for your mesh.

Quick Start
Pre-built Image (Recommended)
No build step required — just run:
docker run -d --name corescope \
--restart=unless-stopped \
-p 80:80 -p 1883:1883 \
-v /your/data:/app/data \
ghcr.io/kpa-clawbot/corescope:latest
Open http://localhost — done. No config file needed; CoreScope starts with sensible defaults.
For HTTPS with a custom domain, add -p 443:443 and mount your Caddyfile:
docker run -d --name corescope \
--restart=unless-stopped \
-p 80:80 -p 443:443 -p 1883:1883 \
-v /your/data:/app/data \
-v /your/Caddyfile:/etc/caddy/Caddyfile:ro \
-v /your/caddy-data:/data/caddy \
ghcr.io/kpa-clawbot/corescope:latest
Disable built-in services with -e DISABLE_MOSQUITTO=true or -e DISABLE_CADDY=true, or drop a .env file in your data volume. See docs/deployment.md for the full reference.

Browser
Two-process model: The Go ingestor handles MQTT ingestion and packet decoding. The Go HTTP server loads all packets into an in-memory store on startup (5 indexes for fast lookups) and serves the REST API + WebSocket broadcast. Both are managed by supervisord inside a single container with Caddy for HTTPS and Mosquitto for local MQTT.
MQTT Setup
- Flash an observer node with
MESH_PACKET_LOGGING=1build flag - Connect via USB to a host running meshcoretomqtt
- Configure meshcoretomqtt with your IATA region code and MQTT broker address
- Packets appear on topic
meshcore/{IATA}/{PUBKEY}/packets
Or POST raw hex packets to POST /api/packets for manual injection.
