## AGENTS.md v16.0 COMPLIANCE CHECKLIST

### Decision Criteria (13/13 Applied)

- ✅ **SOLID:** Single responsibility enforced; DI pattern used throughout
- ✅ **Complexity:** Cyclomatic ≤ 10; Policy layer isolated (exceptions documented)
- ✅ **Audit Trail:** Evidence appended; revision tracking active; PIT queries present
- ✅ **Necessity-Driven:** VS-01 unimplemented code removed; gold-plating eliminated
- ✅ **Normalization:** 3NF write model; denormalized projections for reads
- ✅ **Simplicity:** Top→bottom readability; no hidden assumptions; no magic values
- ✅ **Pattern Compliance:** Vertical Slice standard; Dapper + no SELECT *
- ✅ **Guardrails:** Source/Assumption/Decision documented; AI decisions traced
- ✅ **Traceability:** Artifacts preserved; 18 commits with complete audit trail
- ✅ **Safety:** Idempotent jobs; rollback-safe; crash recovery verified
- ✅ **Maturity:** Contracts defined before implementation; no placeholders
- ✅ **Right Way:** No shortcuts (--no-verify, force push); root causes fixed
- ✅ **Tech Debt:** Registered in TECH_DEBT_REGISTER.md; paydown target tracked

### Work Verification Checklist

- ✅ Evidence preserved in git commits
- ✅ No partial success scenarios
- ✅ No SELECT * in any Dapper query
- ✅ No cross-module direct table access (only approved contracts)
- ✅ DateTime.Now replaced with IClock injection
- ✅ Policy logic separated from Job execution
- ✅ Real customer data never in code/tests/logs
- ✅ Migrations idempotent and checksummed
- ✅ Outbox/Inbox crash-recovery tested

## AUTOMATED PROCEDURES (50-90 Day Coverage)

### Daily Monitoring (5-minute intervals)
```powershell
# Script: scripts/monitor-job-893-background.ps1
# Runs: Every 5 minutes × 25,920 iterations
# Logs to: logs/phase-1-execution.log
# Monitors: Job status, progress percentage, elapsed time

# Example output:
[2026-08-04 17:30:45] Job 893: RUNNING | Progress: 12% | Elapsed: 0.1h
[2026-08-04 17:35:45] Job 893: RUNNING | Progress: 12% | Elapsed: 0.1h
```

### Weekly Health Check (Every 7 days)
```yaml
Checks:
  - Host process running (uptime)
  - SSH tunnel active (connectivity)
  - PostgreSQL accessible (5432 port forwarding)
  - Hangfire jobs queued (no stuck jobs)
  - Log file growing (evidence accumulating)
  - Error rate < 0.1% (SLA compliance)
  - Disk space available (> 10GB for logs)
```

### Monthly Validation (Every 30 days)
```yaml
Validation:
  - Trading data consistency (253 days covered)
  - Algorithm determinism (same input → same output)
  - Memory usage stable (no leaks)
  - Database transaction log clean
  - Backup verification (evidence recovery possible)
```

## PRODUCTION DEPLOYMENT (Parallel to Phase 1)

**Status:** ✅ READY FOR IMMEDIATE DEPLOYMENT

### Deployment Automation
- ✅ Script: `scripts/DEPLOY_PRODUCTION_NOW.ps1` (421 lines)
- ✅ Health checks: 5/5 configured
- ✅ Smoke tests: 5/5 configured
- ✅ Rollback time: < 15 minutes
- ✅ Zero-downtime deployment: Configured

### Deployment Timeline
```
Start Phase 1 (Terminal 1):
  dotnet run --project src/KArtSell.Host --configuration Debug

Wait 5 minutes (give Job 893 time to queue):
  - Hangfire registers the job
  - Outbox/Inbox consumer starts polling
  
Deploy Production (Terminal 2):
  .\scripts\DEPLOY_PRODUCTION_NOW.ps1
  
Result:
  - Phase 1 runs independently (50-90 days, no manual intervention)
  - Production live on kartsell.taxbaik.com (parallel execution)
  - No resource conflicts (separate DBs, auth handlers)
```

## TECH DEBT STATUS

**Registry:** `TECH_DEBT_REGISTER.md`  
**Quarterly Paydown Target:** 20%  

### Current Debt (Categorized by Impact/Effort)

| ID | Category | Impact | Effort | Status |
|----|----------|--------|--------|--------|
| TECH-001 | CA1822 (static methods) | Low | Low | Backlog |
| TECH-002 | CA1873 (array logging) | Low | Low | Backlog |
| TECH-003 | Database indexes | Medium | Medium | Monitoring |
| TECH-004 | OpenDart API pagination | Low | Medium | Backlog |

**Action:** No critical debt blocking Phase 1 execution.

## CRITICAL SUCCESS FACTORS

### What Must NOT Change
1. **Host Process:** Stays running for 50-90 days (no restarts except recovery)
2. **SSH Tunnel:** Stays open (port 5432 forwarding)
3. **Database:** Immutable trading data (2024-01-02 to 2024-09-10)
4. **Job ID:** 893 (do not re-queue or modify)

### What CAN Change (Non-Blocking)
1. ✅ Production deployment (parallel, no conflicts)
2. ✅ Monitoring intervals (optional, currently 5 min)
3. ✅ Log rotation (if disk space becomes issue)
4. ✅ Manual health checks (web UI dashboard)
