CHANGELOG — Corrosion Admin Panel

All notable changes to this project will be documented in this file.

[Unreleased]

Added (Phase 2.2 — Player Retention Analytics)

Backend:

• Migration 004_player_sessions.sql — Player session tracking table with indexes for retention queries
• backend/src/db/player_sessions.rs — Complete player session tracking and retention analysis:
  • track_player_join() / track_player_leave() — Record individual player sessions
  • calculate_retention_after_wipe() — Calculate 24h/48h/72h return rates per wipe
  • get_unique_player_count() / get_avg_session_duration() — Session metrics
  • get_new_vs_returning_ratio() — New vs returning player analysis
  • get_recent_wipe_retention_metrics() — Multi-wipe retention trends
  • cleanup_old_player_sessions() — 90-day retention cleanup
• backend/src/api/plugin.rs — Plugin event endpoints:
  • POST /api/plugin/player-event — Track player join/leave events
  • POST /api/plugin/checkin — Plugin registration on server start
• Extended backend/src/api/analytics.rs with retention endpoints:
  • GET /api/analytics/retention?wipe_count=6 — Multi-wipe retention metrics
  • GET /api/analytics/retention/export — CSV export of retention data

Frontend:

• PlayerRetentionView.vue — Complete retention analytics dashboard:
  • ECharts retention curve (24h/48h/72h lines across multiple wipes)
  • Summary cards: unique players, avg session duration, new vs returning ratio
  • Wipe selector (last 3/6/10/20 wipes)
  • Detailed wipe table with retention percentages
  • CSV export functionality
• Added route /retention to router
• TypeScript interfaces: WipeRetentionMetric, SessionSummary, RetentionResponse

Plugin:

• Updated CorrosionCompanion.cs to track player events via /api/plugin/player-event
• Modified OnPlayerConnected / OnPlayerDisconnected hooks with license_key authentication

Purpose: Answers critical question: "What percentage of players return 24h/48h/72h after a wipe?" Enables data-driven wipe timing optimization and player retention analysis.

Added (Phase 2.2 — Map Analytics System)

Backend:

• Migration 005: Added map_id FK to server_stats and wipe_history for map effectiveness tracking
• Stats consumer now captures current_map_id from server_config when persisting stats
• Map analytics database queries (db/maps.rs):
  • get_map_analytics() — Returns performance metrics per map (avg/peak players, times used, effectiveness score)
  • get_map_population_trends() — Player count trends per map over wipe cycles
  • Effectiveness scoring algorithm: (avg_players / peak_players) * 100
• Analytics API endpoint (api/analytics.rs):
  • GET /api/analytics/maps?range=90d — Map performance summary with rotation effectiveness

Frontend:

• MapAnalyticsView.vue — Complete map effectiveness dashboard with:
  • Summary cards: Best performing map, rotation effectiveness %, total maps tracked
  • ECharts bar chart comparing avg vs peak players per map
  • Sortable performance table with effectiveness color coding (green ≥80%, yellow ≥60%, red <60%)
  • Actionable insights section recommending rotation improvements
  • CSV export functionality
  • Time range selector (30d/90d/all)
• TypeScript types: MapPerformanceMetrics, MapAnalyticsSummary
• Router: Added /maps/analytics route under admin dashboard

Purpose: Answers "Which maps drive the most players? Is my rotation working?" Enables data-driven map selection for wipe day.

Added (Phase 2 — Data Aggregation Pipeline)

Backend:

• Stats ingestion consumer service (stats_consumer.rs) subscribing to corrosion.*.stats NATS subject
• Complete stats database queries (db/stats.rs) with support for:
  • Raw stats insertion and retrieval
  • Hourly aggregation queries
  • Analytics summary calculations (peak/avg players, uptime)
  • Data retention cleanup (7 days raw, 90 days hourly)
• Hourly stats aggregation scheduler job (runs at :05 past every hour)
• Daily cleanup scheduler job (runs at 03:00 UTC)
• Analytics API endpoints (api/analytics.rs):
  • GET /api/analytics/summary — Peak/avg players, uptime percentage
  • GET /api/analytics/timeseries — Time-series data for charting (hourly/raw granularity)
  • GET /api/analytics/export — CSV export of server stats
• Background service initialization in main.rs (stats consumer + scheduler)

Frontend:

• Analytics TypeScript types (AnalyticsSummary, TimeseriesData, HourlyStats)
• Complete AnalyticsView.vue implementation with:
  • Real-time data fetching from analytics API
  • Apache ECharts integration for Player Count and Server Performance charts
  • Time range selector (24h/7d/30d)
  • CSV export functionality
  • Loading states and responsive layout

Infrastructure:

• Made NatsBridge.jetstream public for service consumer access

Added (Sovereign Infrastructure Stack)

Technical Details

Data Flow:

Plugin/Agent publishes stats (60s interval)
  → NATS JetStream (corrosion.*.stats)
  → StatsConsumerService persists to server_stats table
  → Hourly aggregation job rolls up to server_stats_hourly
  → Analytics API queries aggregated data
  → Frontend renders charts via ECharts

Database Schema:

• server_stats table (raw stats, 7-day retention)
• server_stats_hourly table (aggregated hourly data, 90-day retention)

Scheduler Jobs:

• Hourly aggregation: 0 5 * * * * (at :05 past every hour)
• Daily cleanup: 0 0 3 * * * (at 03:00 UTC)

Installation Notes

Frontend:

cd frontend && npm install echarts

Backend: No additional dependencies beyond existing Cargo.toml.

Deferred to Phase 2.2

• Player retention tracking (new vs returning players, session duration)
• Wipe-correlated analytics
• Player activity heatmaps (time-of-day patterns)
• Anomaly alerting system
