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.

## 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
|
||||
|
||||
### Directory 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
|
||||

||||
| .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 |
|
||||
| Node 18 LTS EOL (Apr 2025) | ⚠️ Next quarter | Plan Node 22 rollover | docs/DECISIONS/ADR-FRONTEND-RUNTIME.md |
