revert: aggressive coverage interactions dropped score from 42% to 39%

The page.evaluate() calls corrupting localStorage and firing fake events
caused page error-reloads, losing accumulated coverage. Reverting to
the 42% version which was the actual high water mark.

+# AGENTS.md — MeshCore Analyzer
+
+Guide for AI agents working on this codebase. Read this before writing any code.
+
+## Architecture
+
+Single Node.js server + static frontend. No build step. No framework. No bundler.
+
+```
+server.js          — Express API + MQTT ingestion + WebSocket broadcast
+decoder.js         — MeshCore packet parser (header, path, payload, adverts)
+packet-store.js    — In-memory packet store + query engine (backed by SQLite)
+db.js              — SQLite schema + prepared statements
+public/            — Frontend (vanilla JS, one file per page)
+  app.js           — SPA router, shared globals, theme loading
+  roles.js         — ROLE_COLORS, TYPE_COLORS, health thresholds, shared helpers
+  nodes.js         — Nodes list + side pane + full detail page
+  map.js           — Leaflet map with markers, legend, filters
+  packets.js       — Packets table + detail pane + hex breakdown
+  packet-filter.js — Wireshark-style filter engine (standalone, testable)
+  customize.js     — Theme customizer panel (self-contained IIFE)
+  analytics.js     — Analytics tabs (RF, topology, hash issues, etc.)
+  channels.js      — Channel message viewer
+  live.js          — Live packet feed + VCR mode
+  home.js          — Home/onboarding page
+  hop-resolver.js  — Client-side hop prefix → node name resolution
+  style.css        — Main styles, CSS variables for theming
+  live.css         — Live page styles
+  home.css         — Home page styles
+  index.html       — SPA shell, script/style tags with cache busters
+```
+
+### 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
+
+## 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.
+
+### 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.
+
+### 3. Cache busters — ALWAYS bump them
+Every time you change a `.js` or `.css` file in `public/`, bump the cache buster in `index.html`. This has caused 7 separate production regressions. Use:
+```bash
+NEWV=$(date +%s) && sed -i "s/v=[0-9]*/v=$NEWV/g" public/index.html
+```
+Do this in the SAME commit as the code change, not as a follow-up.
+
+### 4. Verify API response shape before building UI
+Before writing client code that consumes an API endpoint, check what the endpoint ACTUALLY returns. Use `curl` or check the server code. Don't assume fields exist — grouped packets (`groupByHash=true`) have different fields than raw packets. This has caused multiple breakages.
+
+### 5. Plan before implementing
+Present a plan with milestones to the human. Wait for sign-off before starting. The plan must include:
+- What changes in each milestone
+- What tests will be written
+- What browser validation will be done
+- What config/customizer implications exist (see rule 8)
+
+Do NOT start coding until the human says "go" or "start" or equivalent.
+
+### 6. One commit per logical change
+Don't push half-finished work. Don't push "let me try this" experiments. Get it right locally, test it, THEN push ONE commit. The QR overlay took 6 commits because each one was pushed without looking at the result. That's 6x the review burden for one visual change.
+
+### 7. Understand before fixing
+When something doesn't work as expected, INVESTIGATE before "fixing." Read the firmware source. Check the actual data. Understand WHY before changing code. The hash_size saga (21 commits) happened because we guessed at behavior instead of reading the MeshCore source.
+
+### 8. Config values belong in the customizer eventually
+If a feature introduces configurable values (thresholds, timeouts, display limits), note in the plan that these should be exposed in the customizer in a later milestone. It's OK to hardcode initially, but don't forget — track it in the plan.
+
+### 9. Explicit git add only
+Never use `git add -A` or `git add .`. Always list files explicitly: `git add file1.js file2.js`. Review with `git diff --cached --stat` before committing.
+
+### 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.
+
+## 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.
+
+**Before implementing any feature that touches protocol behavior:**
+1. Check the firmware source in `firmware/src/` and `firmware/docs/`
+2. Key files: `Mesh.h` (constants, packet structure), `Packet.cpp` (encoding/decoding), `helpers/AdvertDataHelpers.h` (advert flags/types), `helpers/CommonCLI.cpp` (CLI commands), `docs/packet_format.md`, `docs/payloads.md`
+3. If `firmware/` doesn't exist, clone it: `git clone --depth 1 https://github.com/meshcore-dev/MeshCore.git firmware`
+4. To update: `cd firmware && git pull`
+
+**Do NOT guess at protocol behavior.** The hash_size saga (21 commits) and the advert flags bug (room servers misclassified as repeaters) both happened because we assumed instead of reading the firmware source. The firmware is C++ — read it.
+
+## MeshCore Protocol
+
+**Do not memorize or hardcode protocol details from this file.** Read the firmware source.
+
+- Packet format: `firmware/docs/packet_format.md`
+- Payload types & structures: `firmware/docs/payloads.md`
+- Advert flags & types: `firmware/src/helpers/AdvertDataHelpers.h`
+- Route types & constants: `firmware/src/Mesh.h`
+- CLI commands & behavior: `firmware/docs/cli_commands.md`
+- FAQ (advert intervals, etc.): `firmware/docs/faq.md`
+
+If you need to know how something works — a flag, a field, a timing, a behavior — **open the file and read it.** Don't rely on comments in our code, don't rely on what someone told you, don't guess. The firmware C++ source is the only thing that matters.
+
+## Frontend Conventions
+
+### Theming
+All colors MUST use CSS variables. Never hardcode `#hex` values outside of `:root` definitions. The customizer controls colors via `THEME_CSS_MAP` in customize.js. If you add a new color, add it as a CSS variable and map it in the customizer.
+
+### Shared Helpers (roles.js)
+- `getNodeStatus(role, lastSeenMs)` → 'active' | 'stale'
+- `getHealthThresholds(role)` → `{ staleMs, degradedMs, silentMs }`
+- `ROLE_COLORS`, `ROLE_STYLE`, `TYPE_COLORS` — global color maps
+
+### Shared Helpers (nodes.js)
+- `getStatusInfo(n)` → `{ status, statusLabel, explanation, roleColor, ... }`
+- `renderNodeBadges(n, roleColor)` → HTML string
+- `renderStatusExplanation(n)` → HTML string
+
+### last_heard vs last_seen
+- `last_seen` = DB timestamp, only updates on adverts/direct upserts
+- `last_heard` = from in-memory packet store, updates on ALL traffic
+- Always prefer `n.last_heard || n.last_seen` for display and status calculation
+
+### Packet Filter (packet-filter.js)
+Standalone module. No dependencies on app globals (copies what it needs). Testable in Node.js:
+```bash
+node test-packet-filter.js
+```
+Uses firmware-standard type names (GRP_TXT, TXT_MSG, REQ) with aliases for convenience.
+
+## Testing
+
+### Test Pipeline
+```bash
+npm test                    # all backend tests + coverage summary
+npm run test:unit           # fast: unit tests only (no server needed)
+npm run test:coverage       # all tests + HTML coverage report
+npm run test:full-coverage  # backend + instrumented frontend coverage via Playwright
+```
+
+### Test Files
+```bash
+# Backend (deterministic, run before every push)
+node test-packet-filter.js        # filter engine
+node test-aging.js                # node aging system
+node test-regional-filter.js      # regional observer filtering
+node test-decoder.js              # packet decoder
+node test-decoder-spec.js         # spec-driven + golden fixture tests
+node test-server-helpers.js       # extracted server functions
+node test-server-routes.js        # API route tests via supertest
+node test-packet-store.js         # in-memory packet store
+node test-db.js                   # SQLite operations
+node test-frontend-helpers.js     # frontend logic (via vm.createContext)
+node tools/e2e-test.js            # E2E: temp server + synthetic packets
+node tools/frontend-test.js       # frontend smoke: HTML, JS refs, API shapes
+
+# Frontend E2E (requires running server or Playwright)
+node test-e2e-playwright.js       # 8 Playwright browser tests (default: localhost:3000)
+```
+
+### Rules
+**ALL existing tests must pass before pushing.** No exceptions. No "known failures."
+
+**Every new feature must add tests.** Unit tests for logic, Playwright tests for UI changes. Test count only goes up.
+
+**Coverage targets:** Backend 85%+, Frontend 42%+ (both should only go up). CI reports both and updates badges automatically.
+
+### When writing a new feature
+1. Write the feature code
+2. Write unit tests for the logic
+3. Write/update Playwright tests if it's a UI change
+4. Run `npm test` — all tests must pass
+5. Run `node test-e2e-playwright.js` against a local server — E2E must pass
+6. THEN push to master
+
+### Testing infrastructure
+- **Backend coverage**: c8 tracks server-side code in-process
+- **Frontend coverage**: Istanbul instruments `public/*.js` → Playwright exercises them → `window.__coverage__` extracted → nyc reports. Instrumented files are generated fresh each CI run, never checked in.
+- **CI pipeline**: backend tests + coverage → instrument frontend → start local server → Playwright E2E + coverage collection → badges update → deploy (only if all pass)
+- **Playwright tests default to localhost:3000** — NEVER run against prod. CI sets `BASE_URL=http://localhost:13581`. Running locally: start your server, then `node test-e2e-playwright.js`
+- **ARM machines**: Basic Playwright tests work with system chromium (`CHROMIUM_PATH=/usr/bin/chromium-browser`). Heavy coverage collection scripts may crash — use CI for those.
+
+Tests that need live mesh data can use `https://analyzer.00id.net` — all API endpoints are public, no auth required.
+
+### What Needs Tests
+- Parsers and decoders (packet-filter, decoder)
+- Threshold/status calculations (aging, health)
+- Data transformations (hash size computation, field resolvers)
+- Anything with edge cases (null handling, boundary values)
+- UI interactions that exercise frontend code branches
+
+## Common Pitfalls
+
+| Pitfall | Times it happened | Prevention |
+|---------|-------------------|------------|
+| Forgot cache busters | 7 | Always bump in same commit |
+| Grouped packets missing fields | 3 | curl the actual API first |
+| last_seen vs last_heard mismatch | 4 | Always use `last_heard \|\| last_seen` |
+| CSS selectors don't match SVG | 2 | Manipulate SVG in JS after generation |
+| Feature built on wrong assumption | 5+ | Read source/data before coding |
+| Pushed without testing | 5+ | Run tests + browser check every time |
+| Tests defaulting to prod | 2 | Always default to localhost, never prod |
+| Gave up testing locally | 2 | Basic tests work on ARM — only heavy coverage scripts crash |
+| Copy-pasted functions for "coverage" | 1 | Test the real code, not copies in a helper file |
+| Subagent timed out mid-work | 4 | Give clear scope, don't try to run slow pipelines locally |
+
+## File Naming
+- Tests: `test-{feature}.js` in repo root
+- No build step, no transpilation — write ES2020 for server, ES5/6 for frontend (broad browser support)
+
+## What NOT to Do
+- **Don't check in private information** — no names, API keys, tokens, passwords, IP addresses, personal data, or any identifying information. This is a PUBLIC repo.
+- Don't add npm dependencies without asking
+- Don't create a build step
+- Don't add framework abstractions (React, Vue, etc.)
+- Don't hardcode colors — use CSS variables
+- Don't make per-packet server API calls from the frontend
+- Don't push without running tests
+- Don't start implementing without plan approval

+# CUSTOMIZATION-PLAN.md — White-Label / Multi-Instance Theming
+
+## Status: Phase 1 Complete (v2.6.0+)
+
+### What's Built
+- Floating draggable customizer panel (🎨 in nav)
+- Basic (7 colors) + Advanced (12 colors + fonts) with light/dark mode
+- Node role colors + packet type colors
+- Branding (site name, logo, favicon)
+- Home page content editor with markdown support
+- Auto-save to localStorage + admin JSON export
+- Colors restore on page load before any rendering
+
+### Known Bugs to Fix
+- Nav background sometimes doesn't repaint (gradient caching)
+- Some pages may flash default colors before customization applies
+- Color picker dragging can still feel sluggish on complex pages
+- Reset preview may not fully restore all derived variables
+
+### Next Round: Phase 2
+- **Click-to-identify**: Click any UI element → customizer scrolls to the setting that controls it (like DevTools inspect but for theme colors)
+- **Theme presets**: Built-in themes (Default, Cascadia Navy, Forest Green, Midnight) — one-click switch
+- **Import config**: Paste JSON to load a theme (reverse of export)
+- **Preview home page changes live** without navigating away
+- Fix remaining 8 hardcoded colors from audit (nav stats, trace labels, rec-dot)
+- Hex viewer color customization (Advanced section)
+
+### Architecture Notes
+- `customize.js` MUST load right after `roles.js`, before `app.js` — color restore timing is critical
+- `syncBadgeColors()` in roles.js is the single source for badge CSS
+- `ROLE_STYLE[role].color` must be updated alongside `ROLE_COLORS[role]`
+- Auto-save debounced 500ms, theme-refresh debounced 300ms
+
+## Problem
+
+Regional mesh admins (e.g. CascadiaMesh) fork the analyzer and manually edit CSS/HTML to customize branding, colors, and content. This is fragile — every upstream update requires re-applying customizations.
+
+## Goal
+
+A `config.json`-driven customization system where admins configure branding, colors, labels, and home page content without touching source code. Accessible via a **Tools → Customization** UI that outputs the config.
+
+## Direct Feedback (CascadiaMesh Admin)
+
+Customizations they made manually:
+- **Branding**: Custom logo, favicon, site title ("CascadiaMesh Analyzer")
+- **Colors**: Node type colors (repeaters blue instead of red, companions red)
+- **UI styling**: Custom color scheme (deep navy theme — "Cascadia" theme)
+- **Home page**: Intro section emojis, steps, checklist content
+
+Requested config options:
+- Configurable branding assets (logo, favicon, site name)
+- Configurable UI colors/text labels
+- Configurable node type colors
+- Everything in the intro/home section should be configurable
+

+- Server reads `config.json` theme section
+- New endpoint: `GET /api/config/theme` returns merged theme config
+- Client injects CSS variables from theme config on page load
+- Node type colors configurable via `window.TYPE_COLORS` override
+
+### Phase 2: Branding
+- Config drives nav bar title, logo, favicon
+- `index.html` rendered server-side with branding placeholders OR
+- Client JS replaces branding elements on load from `/api/config/theme`
+
+### Phase 3: Home Page Content
+- Home page sections (hero, steps, checklist, footer) driven by config
+- Default content baked in; config overrides specific sections
+- Emoji + text for each step configurable
+
+### Phase 4: Tools → Customization UI
+- New page `#/customize` (admin only?)
+- Color pickers for theme variables
+- Live preview
+- Branding upload (logo, favicon)
+- Export as JSON config
+- Home page content editor (WYSIWYG-lite)
+
+### Phase 5: CSS Theme Presets
+- Built-in themes: Default (blue), Cascadia (navy), Forest (green), Midnight (dark)
+- One-click theme switching
+- Custom theme = override any variable
+
+## Architecture Notes
+
+- Theme CSS variables are already in `:root {}` — just need to override from config
+- Node type colors used in `roles.js` via `TYPE_COLORS` — make configurable
+- Home page content is in `home.js` — extract to template driven by config
+- Logo/favicon: serve from config-specified path, default to built-in
+- No build step — pure runtime configuration
+- Config changes take effect on page reload (no server restart needed for theme)
+
+## Priority
+
+1. Theme colors (CSS variables from config) — highest impact, lowest effort
+2. Branding (site name, logo) — visible, requested
+3. Node type colors — requested specifically
+4. Home page content — requested
+5. Customization UI — nice to have, lower priority

 > Self-hosted, open-source MeshCore packet analyzer — a community alternative to the closed-source `analyzer.letsmesh.net`.
 
 Collects MeshCore packets via MQTT, decodes them, and presents a full web UI with live packet feed, node map, channel chat, packet tracing, per-node analytics, and more.

-**Persist your database** across container rebuilds by using a named volume (`meshcore-data`) or bind mount (`-v ./data:/app/data`).
+Config lives in the data volume at `/app/data/config.json` — a default is created on first run. To edit it:
+```bash
+docker exec -it meshcore-analyzer vi /app/data/config.json
+```
+
+Or use a bind mount for the data directory:
+```bash
+docker run -d \
+  --name meshcore-analyzer \
+  -p 3000:3000 \
+  -p 1883:1883 \
+  -v ./data:/app/data \
+  meshcore-analyzer
+# Now edit ./data/config.json directly on the host
+```
+
+**Theme customization:** Put `theme.json` next to `config.json` — wherever your config lives, that's where the theme goes. Use the built-in customizer (Tools → Customize) to design your theme, download the file, and drop it in. Changes are picked up on page refresh — no restart needed. The server logs where it's looking on startup.

+# Customizing Your Instance
+
+## Quick Start
+
+1. Open your analyzer in a browser
+2. Go to **Tools → Customize**
+3. Change colors, branding, home page content
+4. Click **💾 Download theme.json**
+5. Put the file next to your `config.json` on the server
+6. Refresh the page — done
+
+No restart needed. The server picks up changes to `theme.json` on every page load.
+
+## Where Does theme.json Go?
+
+**Next to config.json.** However you deployed, put them side by side.
+
+**Docker:**
+```bash
+# Add to your docker run command:
+-v /path/to/theme.json:/app/theme.json:ro
+
+# Or if you bind-mount the data directory:
+# Just put theme.json in that directory
+```
+
+**Bare metal / PM2 / systemd:**
+```bash
+# Same directory as server.js and config.json
+cp theme.json /path/to/meshcore-analyzer/
+```
+
+Check the server logs on startup — it tells you where it's looking:
+```
+[theme] Loaded from /app/theme.json
+```
+or:
+```
+[theme] No theme.json found. Place it next to config.json or in data/ to customize.
+```
+
+## What Can You Customize?
+
+### Branding
+```json
+{
+  "branding": {
+    "siteName": "Bay Area Mesh",
+    "tagline": "Community LoRa mesh network",
+    "logoUrl": "/my-logo.svg",
+    "faviconUrl": "/my-favicon.png"
+  }
+}
+```
+
+Logo replaces the 🍄 emoji in the nav bar (renders at 24px height). Favicon replaces the browser tab icon. Use a URL path for files in the `public/` folder, or a full URL for external images.
+
+### Theme Colors (Light Mode)
+```json
+{
+  "theme": {
+    "accent": "#ff6b6b",
+    "navBg": "#1a1a2e",
+    "navText": "#ffffff",
+    "background": "#f4f5f7",
+    "text": "#1a1a2e",
+    "statusGreen": "#22c55e",
+    "statusYellow": "#eab308",
+    "statusRed": "#ef4444"
+  }
+}
+```
+
+### Theme Colors (Dark Mode)
+```json
+{
+  "themeDark": {
+    "accent": "#57f2a5",
+    "navBg": "#0a0a1a",
+    "background": "#0f0f23",
+    "text": "#e2e8f0"
+  }
+}
+```
+
+Only include colors you want to change — everything else stays default.
+
+### All Available Theme Keys
+
+| Key | What It Controls |
+|-----|-----------------|
+| `accent` | Buttons, links, active tabs, badges, charts |
+| `accentHover` | Hover state for accent elements |
+| `navBg` | Nav bar background (gradient start) |
+| `navBg2` | Nav bar gradient end |
+| `navText` | Nav bar text and links |
+| `navTextMuted` | Inactive nav links, stats |
+| `background` | Main page background |
+| `text` | Primary text color |
+| `textMuted` | Labels, timestamps, secondary text |
+| `statusGreen` | Healthy/online indicators |
+| `statusYellow` | Warning/degraded indicators |
+| `statusRed` | Error/offline indicators |
+| `border` | Dividers, table borders |
+| `surface1` | Card backgrounds |
+| `surface2` | Nested panels |
+| `cardBg` | Detail panels, modals |
+| `contentBg` | Content area behind cards |
+| `detailBg` | Side panels, packet detail |
+| `inputBg` | Text inputs, dropdowns |
+| `rowStripe` | Alternating table rows |
+| `rowHover` | Table row hover |
+| `selectedBg` | Selected/active rows |
+| `font` | Body font stack |
+| `mono` | Monospace font (hex, hashes, code) |
+
+### Node Role Colors
+```json
+{
+  "nodeColors": {
+    "repeater": "#dc2626",
+    "companion": "#2563eb",
+    "room": "#16a34a",
+    "sensor": "#d97706",
+    "observer": "#8b5cf6"
+  }
+}
+```
+
+Affects map markers, packet path badges, node lists, and legends.
+
+### Packet Type Colors
+```json
+{
+  "typeColors": {
+    "ADVERT": "#22c55e",
+    "GRP_TXT": "#3b82f6",
+    "TXT_MSG": "#f59e0b",

+    "PATH": "#14b8a6",
+    "ANON_REQ": "#f43f5e"
+  }
+}
+```
+
+Affects packet badges, feed dots, map markers, and chart colors.
+
+### Home Page Content
+```json
+{
+  "home": {
+    "heroTitle": "Welcome to Bay Area Mesh",
+    "heroSubtitle": "Find your nodes to start monitoring them.",
+    "steps": [
+      { "emoji": "📡", "title": "Connect", "description": "Link your node to the mesh" },

+      { "label": "🗺️ Map", "url": "#/map" }
+    ]
+  }
+}
+```
+
+Step descriptions and checklist answers support Markdown (`**bold**`, `*italic*`, `` `code` ``, `[links](url)`).
+
+## User vs Admin Themes
+
+- **Admin theme** (`theme.json`): Default for all users. Edit the file, refresh.
+- **User theme** (browser): Each user can override the admin theme via Tools → Customize → "Save as my theme". Stored in localStorage, only affects that browser.
+
+User themes take priority over admin themes. Users can reset their personal theme to go back to the admin default.
