+# MeshCore PR Reviewer Agent
+
+You are an expert software engineer specializing in Go and JavaScript-heavy network analysis tools. Your primary role is to act as a meticulous pull request reviewer for the `Kpa-clawbot/meshcore-analyzer` repository. You are deeply familiar with its architecture, as outlined in `AGENTS.md`, and you enforce its rules rigorously.
+
+Your reviews are thorough, constructive, and aimed at maintaining the highest standards of code quality, performance, and stability on both the backend and frontend.
+
+## Core Principles
+
+1.  **Context is King**: Before any review, consult the `AGENTS.md` file in the `Kpa-clawbot/meshcore-analyzer` repository to ground your feedback in the project's established architecture and rules.
+2.  **Enforce the Rules**: Your primary directive is to ensure every rule in `AGENTS.md` is followed. Call out any deviation.
+3.  **Go & JS Best Practices**: Apply your deep knowledge of Go and modern JavaScript idioms. Pay close attention to concurrency, error handling, performance, and state management, especially as they relate to a real-time data processing application.
+4.  **Constructive and Educational**: Your feedback should not only identify issues but also explain *why* they are issues and suggest idiomatic solutions. Your goal is to mentor and elevate the codebase and its contributors.
+5.  **Be a Guardian**: Protect the project from regressions, performance degradation, and architectural drift.
+
+## Review Focus Areas
+
+You will pay special attention to the following areas during your review:
+
+### 1. Architectural Adherence & Design Principles
+- **SOLID & DRY**: Does the change adhere to SOLID principles? Is there duplicated logic that could be refactored? Does it respect the existing separation of concerns?
+- **Project Architecture**: Does the PR respect the single Node.js server + static frontend architecture? Are changes in the right place?
+
+### 2. Testing and Validation
+- **No commit without tests**: Is the backend logic change covered by unit tests? Is `test-packet-filter.js` or `test-aging.js` updated if necessary?
+- **Browser Validation**: Has the contributor confirmed the change works in a browser? Is there a screenshot for visual changes?
+- **Cache Busters**: If any `public/` assets (`.js`, `.css`) were modified, has the cache buster in `public/index.html` been bumped in the *same commit*? This is critical.
+
+### 3. Go-Specific Concerns
+- **Concurrency**: Are goroutines used safely? Are there potential race conditions? Is synchronization used correctly?
+- **Error Handling**: Is error handling explicit and clear? Are errors wrapped with context where appropriate?
+- **Performance**: Are there inefficient loops or memory allocation patterns? Scrutinize any new data processing logic.
+- **Go Idioms**: Does the code follow standard Go idioms and formatting (`gofmt`)?
+
+### 4. Frontend and UI Testability
+- **Acknowledge Complexity**: Does the PR introduce complex client-side logic? Recognize that browser-based functionality is difficult to unit test.
+- **Promote Testability**: Challenge the contributor to refactor UI code to improve testability. Are data manipulation, state management, and rendering logic separated? Logic should be in pure, testable functions, not tangled in DOM manipulation code.
+- **UI Logic Purity**: Scrutinize client-side JavaScript. Are there large, monolithic functions? Could business logic be extracted from event handlers into standalone, easily testable functions?
+- **State Management**: How is client-side state managed? Are there risks of race conditions or inconsistent states from asynchronous operations (e.g., API calls)?
+
+### 5. Observability and Maintainability
+- **Logging**: Are new logic paths and error cases instrumented with sufficient logging to be debuggable in production?
+- **Configuration**: Are new configurable values (thresholds, timeouts) identified for future inclusion in the customizer, as per project rules?
+- **Clarity**: Is the code clear, readable, and well-documented where complexity is unavoidable?
+
+### 6. API and Data Integrity
+- **API Response Shape**: If the PR adds a UI feature that consumes an API, is there evidence the author verified the actual API response?
+- **Firmware as Source of Truth**: For any changes related to the MeshCore protocol, has the author referenced the `firmware/` source? Challenge any "magic numbers" or assumptions about packet structure.
+
+## Review Process
+
+1.  **State Your Role**: Begin your review by announcing your function: "As the MeshCore PR Reviewer, I have analyzed this pull request based on the project's architectural guidelines and best practices."
+2.  **Provide a Summary**: Give a high-level summary of your findings (e.g., "This PR looks solid but needs additions to testing," or "I have several concerns regarding performance and frontend testability.").
+3.  **Detailed Feedback**: Use a bulleted list to present specific, actionable feedback, referencing file paths and line numbers. For each point, cite the relevant principle or project rule (e.g., "Missing Test Coverage (Rule #1)", "UI Logic Purity (Focus Area #4)").
+4.  **End with a Clear Approval Status**: Conclude with a clear statement of "Approved" (with minor optional suggestions), "Changes Requested," or "Rejected" (for significant violations).

+**Project:** CoreScope — Real-time LoRa mesh packet analyzer
 **Stack:** Node.js 18+, Express 5, SQLite (better-sqlite3), vanilla JS frontend, Leaflet maps, WebSocket (ws), MQTT (mqtt)
 **User:** User
 **Description:** Self-hosted alternative to analyzer.letsmesh.net. Ingests MeshCore mesh network packets via MQTT, decodes with custom parser (decoder.js), stores in SQLite with in-memory indexing (packet-store.js), and serves a rich SPA with live visualization, packet analysis, node analytics, channel chat, observer health, and theme customizer. ~18K lines, 14 test files, 85%+ backend coverage. Production at v2.6.0.

 ### Data Flow
-1. MQTT brokers → server.js ingests packets → decoder.js parses → packet-store.js stores in memory + SQLite
-2. WebSocket broadcasts new packets to connected browsers
-3. Frontend fetches via REST API, filters/sorts client-side
+1. MQTT brokers → Go ingestor (`cmd/ingestor/`) ingests packets → decodes → writes to SQLite
+2. Go server (`cmd/server/`) polls SQLite for new packets, broadcasts via WebSocket

+### What's Deprecated (DO NOT TOUCH)
+The following were part of the old Node.js backend and have been removed:
+- `server.js`, `db.js`, `decoder.js`, `server-helpers.js`, `packet-store.js`, `iata-coords.js`
+- All `test-server-*.js`, `test-decoder*.js`, `test-db*.js`, `test-regional*.js` files
+- If you see references to these in comments or docs, they're stale — ignore them
 
 ## Rules — Read These First
 
 ### 1. No commit without tests
-Every change that touches logic MUST have unit tests. Run `node test-packet-filter.js && node test-aging.js` before pushing. If you add new logic, add tests to the appropriate test file or create a new one. No exceptions.
+Every change that touches logic MUST have tests. For Go backend: `cd cmd/server && go test ./...` and `cd cmd/ingestor && go test ./...`. For frontend: `node test-packet-filter.js && node test-aging.js && node test-frontend-helpers.js`. If you add new logic, add tests. No exceptions.
 
 ### 2. No commit without browser validation
 After pushing, verify the change works in an actual browser. Use `browser profile=openclaw` against the running instance. Take a screenshot if the change is visual. If you can't validate it, say so — don't claim it works.
@@ -77,6 +91,9 @@ Never use `git add -A` or `git add .`. Always list files explicitly: `git add fi
 ### 10. Don't regress performance
 The packets page loads 30K+ packets. Don't add per-packet API calls. Don't add O(n²) loops. Client-side filtering is preferred over server-side. If you need data from the server, fetch it once and cache it.
 
+### 11. PR descriptions must be clean markdown
+When opening a pull request, the description must be **valid, readable markdown**. Use real newlines (not `\n` literals), proper code fences, and correct heading syntax. Write it using `--body-file -` (piped from a heredoc or file), never inline `--body` with escaped characters. If the description renders as garbage, fix it before requesting review. This is the first thing reviewers see.

 ## MeshCore Firmware — Source of Truth
 
 The MeshCore firmware source is cloned at `firmware/` (gitignored — not part of this repo). This is THE authoritative reference for anything related to the protocol, packet format, device behavior, advert structure, flags, hash sizes, route types, or how repeaters/companions/rooms/sensors behave.

+# v3.1.0 — Now It's CoreScope
+
+MeshCore Analyzer has a new name: **CoreScope**. Same mesh analysis you rely on, sharper identity, and a boatload of fixes and performance wins since v3.0.0.
+
+48 commits, 30+ issues closed. Here's what changed.
+
+---
+
+## 🏷️ Renamed to CoreScope
+
+The project is now **CoreScope** — frontend, backend, Docker images, manage.sh, docs, CI — everything has been updated. The URL, the API, the database, and your config all stay the same. Just a better name for the tool the community built.
+
+---
+
+## ⚡ Performance
+
+| What | Before | After |
+|------|--------|-------|
+| Subpath analytics | 900 ms | **5 ms** (precomputed at ingest) |
+| Distance analytics | 1.2 s | **15 ms** (precomputed at ingest) |
+| Packet ingest (prepend) | O(n) slice copy | **O(1) append** |
+| Go runtime stats | GC stop-the-world on every call | **cached ReadMemStats** |
+| All analytics endpoints | computed per-request | **TTL-cached** |
+
+The in-memory store now precomputes subpaths and distance data as packets arrive, eliminating expensive full-table scans on the analytics endpoints. The O(n) slice prepend on every ingest — the single hottest line in the server — is gone. `ReadMemStats` calls are cached to prevent GC pause spikes under load.
+
+---
+
+## 🆕 New Features
+
+### Telemetry Decode
+Sensor nodes now report **battery voltage** and **temperature** parsed from advert payloads. Telemetry is gated on the sensor flag — only real sensors emit data, and 0°C is no longer falsely reported. Safe migration with `PRAGMA` column checks.
+
+### Channel Decryption for Custom Channels
+The `hashChannels` config now works in the Go ingestor. Key derivation has been ported from Node.js with full AES-128-ECB support and garbage text detection — wrong keys silently fail instead of producing garbled output.
+
+### Node Pruning
+Stale nodes are automatically moved to an `inactive_nodes` table after the configurable retention window. Pruning runs hourly. Your active node list stays clean. (#202)
+
+### Duplicate Node Name Badges
+Nodes with the same display name but different public keys are flagged with a badge so you can spot collisions instantly.
+
+### Sortable Channels Table
+Channel columns are now sortable with click-to-sort headers. Sort preferences persist in `localStorage` across sessions. (#167)
+
+### Go Runtime Metrics
+The performance page exposes goroutine count, heap allocation, GC pause percentiles, and memory breakdown when connected to a Go backend.
+
+---
+
+## 🐛 Bug Fixes
+
+- **Channel decryption regression** (#176) — full AES-128-ECB in Go, garbage text detection, hashChannels key derivation ported correctly (#218)
+- **Packets page not live-updating** (#172) — WebSocket broadcast now includes the nested packet object and timestamp fields the frontend expects; multiple fixes across broadcast and render paths
+- **Node detail page crashes** (#190) — `Number()` casts and `Array.isArray` guards prevent rendering errors on unexpected data shapes
+- **Observation count staleness** (#174) — trace page and packet detail now show correct observation counts
+- **Phantom node cleanup** (#133) — `autoLearnHopNodes` no longer creates fake nodes from 1-byte repeater IDs
+- **Advert count inflation** (#200) — counts unique transmissions, not total observations (8 observers × 1 advert = 1, not 8)
+- **SQLite BUSY contention** (#214) — `MaxOpenConns(1)` + `MaxIdleConns(1)` serializes writes; load-tested under concurrent ingest
+- **Decoder bounds check** (#183) — corrupt/malformed packets no longer crash the decoder with buffer overruns
+- **noise_floor / battery_mv type mismatches** — consistent `float64` scanning handles SQLite REAL values correctly
+- **packetsLastHour always zero** (#182) — early `break` in observer loop prevented counting
+- **Channels stale messages** (#171) — latest message sorted by observation timestamp, not first-seen
+- **pprof port conflict** — non-fatal bind with separate ports prevents Go server crash on startup
+
+---
+
+## ♿ Accessibility & 📱 Mobile
+
+### WCAG AA Compliance (10 fixes)
+- Search results keyboard-accessible with `tabindex`, `role`, and arrow-key navigation (#208)
+- 40+ table headers given `scope` attributes (#211)
+- 9 Chart.js canvases given accessible names (#210)
+- Form inputs in customizer/filters paired with labels (#212)
+
+### Mobile Responsive
+- **Live page**: bottom-sheet panel instead of full-screen overlay (#203)
+- **Perf page**: responsive layout with stacked cards (#204)
+- **Nodes table**: column hiding at narrow viewports (#205)
+- **Analytics/Compare**: horizontal scroll wrappers (#206)
+- **VCR bar**: 44px minimum touch targets (#207)
+
+---
+
+## 🏗️ Infrastructure
+
+### manage.sh Refactored (#230)
+`manage.sh` is now a thin wrapper around `docker compose` — no custom container management, no divergent logic. It reads `.env` for data paths, matching how `docker-compose.yml` works. One source of truth.
+
+### .env Support
+Data directory, ports, and image tags are configured via `.env`. Both `docker compose` and `manage.sh` read the same file.
+
+### Branch Protection & CI on PRs
+- Branch protection enabled on `master` — CI must pass, PRs required
+- CI now triggers on `pull_request`, not just `push` — catch failures before merge (#199)
+
+### Protobuf API Contract
+10 `.proto` files, 33 golden fixtures, CI validation on every push. API shape drift is caught automatically.
+
+### pprof Profiling
+Controlled by `ENABLE_PPROF` env var. When enabled, exposes Go profiling endpoints on separate ports — zero overhead when off.
+
+### Test Coverage
+- Go backend: **92%+** coverage
+- **49 Playwright E2E tests**
+- Both tracks gate deploy in CI
+
+---
+
+## 📦 Upgrading
+
+```bash
+git pull
+./manage.sh stop
+./manage.sh setup
+```
+
+That's it. Your existing `config.json` and database work as-is. The rename is cosmetic — no schema changes, no API changes, no config changes.
+
+### Verify
+
+```bash
+curl -s http://localhost/api/health | grep engine
+# "engine": "go"
+```
+
+---
+
+## ⚠️ Breaking Changes
+
+**None.** All API endpoints, WebSocket messages, and config options are backwards-compatible. The rename affects branding only — Docker image names, page titles, and documentation.

+# CoreScope Migration Guide
+
+MeshCore Analyzer has been renamed to **CoreScope**. This document covers what you need to update.
+
+## What Changed
+
+- **Repository name**: `meshcore-analyzer` → `corescope`
+- **Docker image name**: `meshcore-analyzer:latest` → `corescope:latest`
+- **Docker container prefixes**: `meshcore-*` → `corescope-*`
+- **Default site name**: "MeshCore Analyzer" → "CoreScope"
+
+## What Did NOT Change
+
+- **Data directories** — `~/meshcore-data/` stays as-is
+- **Database filename** — `meshcore.db` is unchanged
+- **MQTT topics** — `meshcore/#` topics are protocol-level and unchanged
+- **Browser state** — Favorites, localStorage keys, and settings are preserved
+- **Config file format** — `config.json` structure is the same
+
+---
+
+## 1. Git Remote Update
+
+Update your local clone to point to the new repository URL:
+
+```bash
+git remote set-url origin https://github.com/Kpa-clawbot/corescope.git
+git pull
+```
+
+## 2. Docker (manage.sh) Users
+
+Rebuild with the new image name:
+
+```bash
+./manage.sh stop
+git pull
+./manage.sh setup
+```
+
+The new image is `corescope:latest`. You can clean up the old image:
+
+```bash
+docker rmi meshcore-analyzer:latest
+```
+
+## 3. Docker Compose Users
+
+Rebuild containers with the new names:
+
+```bash
+docker compose down
+git pull
+docker compose build
+docker compose up -d
+```
+
+Container names change from `meshcore-*` to `corescope-*`. Old containers are removed by `docker compose down`.
+
+## 4. Data Directories
+
+**No action required.** The data directory `~/meshcore-data/` and database file `meshcore.db` are unchanged. Your existing data carries over automatically.
+
+## 5. Config
+
+If you customized `branding.siteName` in your `config.json`, update it to your preferred name. Otherwise the new default "CoreScope" applies automatically.
+
+No other config keys changed.
+
+## 6. MQTT
+
+**No action required.** MQTT topics (`meshcore/#`) are protocol-level and are not affected by the rename.
+
+## 7. Browser
+
+**No action required.** Bookmarks/favorites will continue to work at the same host and port. localStorage keys are unchanged, so your settings and preferences are preserved.
+
+## 8. CI/CD
+
+If you have custom CI/CD pipelines that reference:
+
+- The old repository URL (`meshcore-analyzer`)
+- The old Docker image name (`meshcore-analyzer:latest`)
+- Old container names (`meshcore-*`)
+
+Update those references to use the new names.
+
+---
+
+## Summary Checklist
+
+| Item | Action Required? | What to Do |
+|------|-----------------|------------|
+| Git remote | ✅ Yes | `git remote set-url origin …corescope.git` |
+| Docker image | ✅ Yes | Rebuild; optionally `docker rmi` old image |
+| Docker Compose | ✅ Yes | `docker compose down && build && up` |
+| Data directories | ❌ No | Unchanged |
+| Config | ⚠️ Maybe | Only if you customized `branding.siteName` |
+| MQTT | ❌ No | Topics unchanged |
+| Browser | ❌ No | Settings preserved |
+| CI/CD | ⚠️ Maybe | Update if referencing old repo/image names |
