feat(wbs): AEG-X-001 cross-version test matrix implementation

AEG-X-001: Version Support Policy & Cross-Version Test Coverage Matrix

Implementation:
1. docs/CURRENT/AEG-X-001_VERSION_SUPPORT_POLICY.md
   - Approved version ranges: .NET 8/10, PostgreSQL 14/15/16, Node.js 22
   - Cross-version test scope: Build/Unit/Integration/DbUp/Outbox
   - CI/CD automation strategy and evidence preservation

2. .gitea/workflows/cross-version-matrix.yml
   - 6x3 matrix: .NET 8/10 × PostgreSQL 14/15/16
   - Per-version: Build + Unit/Integration/DbUp/Outbox tests
   - Frontend build (Node 22 + pnpm 10)
   - Migration rehearsal (PG 14/15/16 fresh/re-run/idempotent)
   - Evidence collection: evidence/AEG-X-001/{net*-pg*/,logs/}

Principles Applied:
- 현장감 (실제 CI/CD 실행)
- 재현성 (모든 버전 조합 테스트)
- 이력성 (모든 증거 저장)
- 안정성 (부분 실패 허용, 전체 증거 수집)
- 정규화 (버전별 일관된 테스트)

Next Step: Manual CI run to collect cross-version evidence for AEG-X-001 completion.

# AEG-X-001: Version Support Policy & Cross-Version Test Matrix
**Status:** ✅ DECISION APPROVED (2026-08-17)
**Owner:** Architecture Lead / DevOps
**Requirement:** REQ-PLAT-001 (Version Coverage Matrix)
**Gateway:** G0 (Platform Foundation)

## 1. Approved Version Support Range
### .NET Framework Support Matrix
| Version | Release | LTS | EOL | Status | Support |
|---------|---------|-----|-----|--------|---------|
| **.NET 8** | Nov 2023 | ✅ 3yr LTS | Nov 2026 | ✅ CURRENT | Legacy (maintenance only) |
| **.NET 10** | Nov 2024 | ✅ 8yr LTS | Nov 2032 | ✅ CURRENT | **Primary Support** |
| **.NET 12** | Nov 2025 | ✅ 8yr LTS | Nov 2033 | 📅 PLANNED | Future support (v12.0+ GA approval pending) |
**Decision: Primary = .NET 10 (LTS), Secondary = .NET 8 (legacy), Future = .NET 12**
### PostgreSQL Version Support
| Version | Release | LTS | EOL | Status | Support |
|---------|---------|-----|-----|--------|---------|
| **PostgreSQL 13** | Oct 2020 | ✅ 5yr LTS | Oct 2025 | ⚠️ EOL | Maintenance only |

| **PostgreSQL 15** | Oct 2022 | ✅ 5yr LTS | Oct 2027 | ✅ CURRENT | **Primary Support** |
| **PostgreSQL 16** | Oct 2023 | ✅ 5yr LTS | Oct 2028 | ✅ CURRENT | **Primary Support** |
**Decision: Primary = PostgreSQL 15/16, Legacy = PostgreSQL 14**
### Node.js / pnpm Support
| Component | Version | LTS | Status | Support |
|-----------|---------|-----|--------|---------|

## 2. Cross-Version Test Coverage Matrix
### Test Scope Per Framework Version
| Test Level | .NET 8 | .NET 10 | .NET 12 | Requirement |
|-----------|--------|---------|---------|------------|
| Build | ✅ YES | ✅ YES | 📅 PLANNED | Restore + compile (no runtime) |
| Unit Tests | ✅ YES | ✅ YES | 📅 PLANNED | dotnet test (xUnit, isolated) |
| Integration Tests | ✅ YES | ✅ YES | 📅 PLANNED | Real DB, migration, async |
| DbUp Migration | ✅ YES | ✅ YES | 📅 PLANNED | Fresh/upgrade/re-run/failure recovery |
| Outbox/Inbox | ✅ YES | ✅ YES | 📅 PLANNED | Async replay, idempotency |
| E2E (Host + Frontend) | ✅ SMOKE | ✅ FULL | 📅 PLANNED | ShadowRun API, Host startup |
### Database Version Compatibility (Independent Test)
| Operation | PG 14 | PG 15 | PG 16 | Requirement |
|-----------|-------|-------|-------|------------|
| Fresh Migration | ✅ YES | ✅ YES | ✅ YES | 0000-0041 schema + DDL |
| Upgrade (14→16) | ⚠️ N/A | ✅ YES | ✅ YES | Data preservation + no downtime |
| Re-run (idempotent) | ✅ YES | ✅ YES | ✅ YES | DbUp checksums match |
| Failure Recovery | ✅ YES | ✅ YES | ✅ YES | Rollback + retry scenarios |

## 3. CI/CD Cross-Version Automation
### Job: `cross-version-matrix` (Gitea Actions)
**Trigger:** Every push to `main` (blocking gate)
#### Stage 1: Backend Cross-Version Test
```bash
# Matrix: [[dotnet: 8, 10], [postgres: 14, 15, 16]]
for dotnet_version in 8 10; do
for postgres_version in 14 15 16; do
dotnet restore KArtSell.sln --framework net${dotnet_version}0
dotnet build KArtSell.sln -c Release --no-restore
dotnet test KArtSell.sln -c Release --no-build --logger trx --results-directory evidence/AEG-X-001/net${dotnet_version}0-pg${postgres_version}/
done
done
# Evidence stored: evidence/AEG-X-001/net{8,10}0-pg{14,15,16}/*.trx
```
#### Stage 2: Frontend Build (Single Version)
```bash
# Node.js 22 LTS + pnpm 10 only (no cross-version needed)
cd frontend
pnpm install --frozen-lockfile
pnpm typecheck
pnpm build
# Evidence: frontend/dist (gzip sizes logged)
```
#### Stage 3: Database Migration Rehearsal (Per PG Version)
```bash
# Matrix: [postgres: 14, 15, 16]
for postgres_version in 14 15 16; do
# Fresh migration
dotnet run --project src/KArtSell.DbMigrator -c Release
# Re-run (idempotent)
dotnet run --project src/KArtSell.DbMigrator -c Release
# Evidence: evidence/AEG-X-001/migration-pg${postgres_version}.log
done
```

## 4. Evidence Preservation & Artifact Structure

```
### Artifact Tracking (SHA256)
Each run generates:
- **Build artifacts**: `net{8,10}0-{date}.zip` (gzip measured)
- **Test results**: `.trx` files with pass/fail counts
- **Migration logs**: Text logs with checksum validation
- **Summary**: Per-version pass/fail matrix

| Issue | Impact | Mitigation | Evidence |
|-------|--------|-----------|----------|
| .NET 12 not GA | 📅 Future builds unavailable | PLANNED status, skip in CI for now | .gitea/workflows conditional logic |
| PG 13 EOL (Oct 2025) | ⚠️ Maintenance window | Drop from primary, keep docs | VERSION_COVERAGE_MATRIX.md |
