# CHANGELOG — Corrosion Admin Panel

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

## [Unreleased]

### 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)

**Services Deployed:**
- **Gitea** (git.corrosionmgmt.com) — Self-hosted Git with Actions support
  - Container: `corrosion-gitea` on port 8090 (HTTP) and 8095 (SSH)
  - SQLite database (self-contained, persistent)
  - Replaces GitHub dependency for source control
  - Gitea Actions enabled for CI/CD
- **SeaweedFS** (cdn.corrosionmgmt.com) — S3-compatible object storage and CDN
  - Container: `corrosion-cdn` with integrated Master/Volume/Filer/S3
  - Filer UI at port 8091 (cdn.corrosionmgmt.com)
  - Master UI at port 8093 (admin.cdn.corrosionmgmt.com)
  - S3 API at port 8092 (internal access)
  - Purpose: Map hosting, plugin packages, companion binaries, backups
- **Gitea Act Runner** (asgard build server) — CI/CD execution environment
  - Runs on Ryzen 9 7945HX (16C/32T, 64GB DDR5)
  - Docker-based job execution
  - Go 1.21+ and Rust toolchains available
  - Connects to public Gitea instance remotely

**CI/CD Workflows:**
- `test-runner.yml` — Runner capability validation (hostname, resources, toolchains)
- `build-companion.yml` — Production companion agent build pipeline:
  - Triggers on version tags (v*.*.*)
  - Cross-compiles for Linux AMD64 and Windows AMD64
  - Generates SHA256 checksums
  - Creates Gitea release with auto-generated installation instructions
  - Uploads binaries and checksums as release assets

**Documentation:**
- `infra/docker-compose.yml` — Infrastructure stack definition
- `infra/README.md` — Deployment guide and architecture overview
- `infra/NPM-CONFIG.md` — Nginx Proxy Manager configuration
- `infra/ASGARD-RUNNER.md` — Act runner setup guide

**Repository Migration:**
- Migrated from GitHub to self-hosted Gitea
- Remote updated to `git@git.corrosionmgmt.com:vantzs/corrosion-admin-panel.git`
- All future development on sovereign infrastructure

### 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:**
```bash
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
