+# 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 |
