# DAL Consolidation Archive

**Completed:** 2025-12-27

## Summary

This archive contains all sprint files for the DAL (Data Access Layer) Consolidation initiative, which migrated StellaOps from fragmented storage patterns (`*.Storage.Postgres`, `*.Storage.InMemory`, `*.Persistence.EfCore`) to a unified `*.Persistence` pattern.

## Final State

| Category | Count | Notes |
|----------|-------|-------|
| Modules with `*.Persistence` | 18 | Standard pattern |
| Modules with Infrastructure pattern | 4 | Orchestrator, EvidenceLocker, ExportCenter, TimelineIndexer |
| Modules with `*.Storage` naming | 1 | Scanner (established pattern) |
| Modules with shared library pattern | 1 | Signer (uses KeyManagement) |

## Decisions Made

1. **SQL migrations remain source of truth** - Database-first approach maintained
2. **EF Core scaffolds from live database** - Supports hybrid Raw SQL + EF Core
3. **InMemory for testing only** - Production uses PostgreSQL
4. **Some modules keep Infrastructure pattern** - Orchestrator, EvidenceLocker, ExportCenter, TimelineIndexer have unique workflow requirements
5. **Scanner keeps Storage naming** - Established pattern with 27 migrations
6. **Signer uses shared library** - KeyManagement library provides DB access
