docs: Major documentation reorganization + ENV variable reference
**Documentation Structure:** - Created docs/ subdirectory organization (analysis/, architecture/, bugs/, cluster/, deployments/, roadmaps/, setup/, archived/) - Moved 68 root markdown files to appropriate categories - Root directory now clean (only README.md remains) - Total: 83 markdown files now organized by purpose **New Content:** - Added comprehensive Environment Variable Reference to copilot-instructions.md - 100+ ENV variables documented with types, defaults, purpose, notes - Organized by category: Required (Drift/RPC/Pyth), Trading Config (quality/ leverage/sizing), ATR System, Runner System, Risk Limits, Notifications, etc. - Includes usage examples (correct vs wrong patterns) **File Distribution:** - docs/analysis/ - Performance analyses, blocked signals, profit projections - docs/architecture/ - Adaptive leverage, ATR trailing, indicator tracking - docs/bugs/ - CRITICAL_*.md, FIXES_*.md bug reports (7 files) - docs/cluster/ - EPYC setup, distributed computing docs (3 files) - docs/deployments/ - *_COMPLETE.md, DEPLOYMENT_*.md status (12 files) - docs/roadmaps/ - All *ROADMAP*.md strategic planning files (7 files) - docs/setup/ - TradingView guides, signal quality, n8n setup (8 files) - docs/archived/2025_pre_nov/ - Obsolete verification checklist (1 file) **Key Improvements:** - ENV variable reference: Single source of truth for all configuration - Common Pitfalls #68-71: Already complete, verified during audit - Better findability: Category-based navigation vs 68 files in root - Preserves history: All files git mv (rename), not copy/delete - Zero broken functionality: Only documentation moved, no code changes **Verification:** - 83 markdown files now in docs/ subdirectories - Root directory cleaned: 68 files → 0 files (except README.md) - Git history preserved for all moved files - Container running: trading-bot-v4 (no restart needed) **Next Steps:** - Create README.md files in each docs subdirectory - Add navigation index - Update main README.md with new structure - Consolidate duplicate deployment docs - Archive truly obsolete files (old SQL backups) See: docs/analysis/CLEANUP_PLAN.md for complete reorganization strategy

||||
|
||||
## Current State (Nov 25, 2025)
|
||||
|
||||
✅ **FULLY AUTOMATED HA INFRASTRUCTURE:**
|
||||
- Primary server: srvdocker02 (95.216.52.28) - trading-bot-v4:3001
|
||||

||||
- Zero downtime: Secondary took over seamlessly
|
||||
- Automatic failback: Immediate when primary recovered
|
||||
- Complete cycle: ~7 minutes from failure to restoration

|
||||
|
||||
**Completed:** November 20-25, 2025
|
||||
**Result:** DNS failover monitor v2 with JSON validation, logs all state changes, Telegram notifications integrated
|
||||
|
||||
---
|
||||
|
||||
## Phase 4: DNS-Based Automatic Failover ✅ COMPLETE
|
||||
|
||||
**Goal:** Automatic traffic routing to active server
|
||||
|
||||
**Implementation:** DNS-based Failover with INWX API
|
||||
|
||||
**Tasks:**
|
||||
- [x] Evaluate infrastructure options (chose DNS-based)
|
||||
- [x] Implement automatic DNS updates via INWX API

||||
- [x] Test failover scenarios (primary crash, network partition)
|
||||
- [x] Verify TradingView webhooks route correctly
|
||||
|
||||
**Completed:** November 25, 2025
|
||||
**Live Test Results:**
|
||||
- Detection: 90 seconds (3 × 30s checks)
|
||||
- Failover: <1 second DNS update
|
||||
- Zero downtime: Secondary served traffic immediately
|
||||
- Failback: Automatic when primary recovered
|
||||
|
||||
**Acceptance Criteria:** ✅ ALL MET
|
||||
- TradingView webhooks automatically route to active server ✅
|
||||
- Failover completes within 2 minutes with zero manual intervention ✅
|
||||
- No duplicate trades during failover window ✅
|
||||
- n8n workflows continue without reconfiguration ✅
|
||||
|
||||
---
|
||||
|
||||
## Phase 5: Automated Failover Controller ✅ COMPLETE

|
||||
- [x] Configure automatic DNS switching on failure detection
|
||||
- [x] Implement split-brain prevention (only secondary monitors)
|
||||
- [x] Test recovery scenarios (primary comes back online)
|
||||
- [x] Setup automatic failback on recovery
|
||||
|
||||
**Completed:** November 25, 2025
|
||||
**Result:** Fully autonomous system with automatic failover and failback
|
||||
|
||||
**Acceptance Criteria:** ✅ ALL MET
|
||||

|
||||
- Primary automatically resumes when recovered ✅
|
||||
- No manual intervention required for 99% of failures ✅
|
||||
- Telegram notifications for all state changes ✅
|
||||

## Phase 6: Geographic Redundancy ⏭️ SKIPPED
|
||||
|
||||
**Status:** Not needed at current scale
|
||||
|
||||
**Rationale:**
|
||||
- Single-region HA sufficient for trading bot use case
|
||||
- Primary and secondary in different data centers
|
||||
- DNS-based failover provides adequate redundancy
|
||||
- Cost vs benefit doesn't justify multi-region deployment
|
||||
|
||||
**Revisit when:**
|
||||
- Trading capital exceeds $100,000
|
||||
- Global user base requires lower latency
|
||||
- Regulatory requirements mandate geographic distribution
|
||||
|
||||

|
||||
|
||||
## ✅ PROJECT COMPLETE
|
||||
|
||||
