Add POLO Score and Display Total Nodes in Dashboard

Overview

This PR:

1. enhances the registry dashboard to display POLO scores for each node, providing visibility into node reputation and performance. It includes comprehensive filtering and sorting capabilities to help users identify high-performing nodes at a glance.
2. Shows total registered Nodes alongside online nodes

Changes

Backend (Registry Server)

• Added PoloScore field to DashboardNode struct (pkg/registry/server.go)
  • Exposes POLO score in the dashboard API response
  • Integrates with existing node reputation system

Frontend (Dashboard UI)

• New POLO Score Column

  • Displays each node's POLO score between Status and Trust columns
  • Color-coded visualization:
    • 🟢 Green (≥50): High reputation nodes
    • 🔵 Blue (≥0): Medium reputation nodes
    • ⚪ Gray (<0): Low reputation nodes

• Enhanced Filtering

  • Filter by tag (existing)
  • Task executors only (existing)
  • NEW: Online nodes only - Filter to show only active nodes

• Advanced Sorting Options

  • Sort by Address (default)
  • NEW: Sort by POLO Score (High-Low) - Find top performers
  • NEW: Sort by POLO Score (Low-High) - Identify nodes needing attention
  • NEW: Sort by Trust Links (High-Low) - Most trusted nodes first
  • NEW: Sort by Status (Online first) - Prioritize active nodes

Testing Infrastructure

• Created tests/pilot_dashboard/ directory

  • seed_dashboard.go - Core seeding logic with POLO scores
  • run_dashboard_test.go - Go test for manual dashboard testing
  • run-dashboard.sh - Bash script for quick local deployment
  • seed_dashboard_main.go - Standalone seed utility
  • README.md - Usage documentation

• Test Data includes:

  • 10 nodes with realistic hostnames
  • POLO scores ranging from 30 to 150
  • Multiple tags (ml, gpu, webserver, database, etc.)
  • 5 task executor nodes
  • 10 bidirectional trust relationships

Usage

View Dashboard with Test Data

./tests/pilot_dashboard/run-dashboard.sh

Then visit: http://127.0.0.1:8080

Run via Go Test

go test -v -run TestRunDashboardWithSeed -timeout=0 ./tests/pilot_dashboard

Screenshots

The dashboard now shows:

• POLO Score column with color-coded values
• Dropdown menu for sorting by various criteria
• Additional "Online only" filter checkbox
• All existing functionality preserved

Benefits

1. Transparency - POLO scores visible for all nodes
2. Easy Discovery - Sort to find highest/lowest scoring nodes
3. Better Monitoring - Quickly identify underperforming nodes
4. Flexible Filtering - Combine multiple filters for precise queries
5. Developer-Friendly - Simple test infrastructure for dashboard development

Breaking Changes

None. This is a backward-compatible enhancement.

Testing

• ✅ All existing tests pass
• ✅ Pre-commit hooks configured and running
• ✅ Dashboard compiles and renders correctly
• ✅ Seed script successfully populates test data
• ✅ Filtering and sorting work as expected

Looks ok to me.
