Mutation test confirmed: reverting cmd/server/store.go:2975 (`setContext(buildHopContextPubkeys(tx, pm))` → `setContext(nil)`) in `buildDistanceIndex` produces failing assertion in `TestTopHopsRespectsContextAcrossAllCallSites`: top-hops ranking flips to `72dddd→8acccc@13.0km` (Berlin↔Berlin misresolution), CA↔CA pair absent. After reverting the mutation, the test passes again. Fixes #1201 ## Summary Pure test addition. No production code changed. Adds regression coverage for the hop disambiguator's tier-1 (neighbor affinity) path and an end-to-end fixture that catches revert-to-nil-context regressions across all 9 call sites of `pm.resolveWithContext`. ## Sub-tasks (all 4 landed) 1. **Tier-1 explicit** — `hop_disambig_tier1_test.go`: - `Tier1_StrongAffinityPicksX` (strong-X edge wins) - `Tier1_StrongAffinityPicksY` (reverse weights — proves score is read) - `Tier1_AmbiguousEdgeSkipsToTier2` (`Ambiguous=true` → skip) 2. **Tier ordering** — `Tier1_BeatsTier2WhenBothSignal` (tier 1 wins when both signal) 3. **Tier-1 fallback** — - `Tier1_EmptyGraphFallsThrough` (graph has no edges for context) - `Tier1_NilGraphFallsThrough` (graph is nil) - `Tier1_ScoresTooCloseFallsThrough` (best < `affinityConfidenceRatio` × runner-up) 4. **End-to-end fixture** — `hop_disambig_e2e_test.go`: - 9 nodes with intentional prefix collisions across SLO/LA/NYC/Berlin (prefix `72`) and SF/CA/Berlin (prefix `8a`); Berlin candidates have `obsCount=200` so they'd win tier-3 absent context. - 50 transmissions path `["72","8a"]`, sender + observer in CA. - Affinity graph seeded with strong `sender↔72aa` and `sender↔8aaa` edges. - Asserts: CA↔CA hop present, no Berlin pubkeys in `distHops`, max distance < 300 km cap. ## TDD exemption Net-new regression-sentinel tests for behavior already correct on master post-#1198. Each test passed on first run (no production bug surfaced). The mutation test on sub-task 4 is the gating proof: forcing `setContext(nil)` at `store.go:2975` makes the test fail with the exact misresolution class the issue describes (Berlin↔Berlin leaks into top-hops). ## Acceptance criteria - [x] Tier-1 affinity test added with 3 cases - [x] Tier-ordering test added - [x] Tier-1 fallback tests added (nil / empty / scores-too-close) - [x] End-to-end fixture added with multi-candidate-prefix nodes - [x] End-to-end fixture fails if any call site reverts to `nil` context (mutation-verified) - [x] Test files live in `cmd/server/` alongside `prefix_map_role_test.go` --------- Co-authored-by: openclaw-bot <bot@openclaw.local> Co-authored-by: corescope-bot <bot@corescope.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

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.
