Release Date: 2026-02-08 Codename: Clean Architecture Status: RELEASED

This release represents a major milestone for the AllSource Event Store platform, achieving 100% completion of all planned Q1 2026 roadmap items with significant architectural improvements across all components.

Clean Architecture & Domain-Driven Design

The Rust Core has been completely refactored following Clean Architecture principles:

• 15+ Value Objects: Type-safe domain primitives with validation
• 6+ Entities: Full DDD entity implementations
• 7+ Repository Implementations: In-memory and RocksDB backends
• 6+ Use Cases: Business logic encapsulation
• Native Search: Vector search + BM25 + Hybrid search
• DI Container: ServiceContainer with builder pattern
• Storage Integrity: SHA-256 checksums, WAL verification
• Partition Monitoring: Hot partition detection, metrics
• 7-Day Stress Tests: Production hardening suite

v0.8.0 Quality Improvements:

• SIMD Filter Refactoring: Removed buggy SIMD timestamp implementations, replaced with reliable scalar iterators following Rust best practices
• Arena Pool Test Fix: Fixed flaky arena allocation tests
• Dependency Updates: Resolved cargo audit vulnerabilities
• 1,221 tests passing with 0 failures

Performance:

• 726K events/sec ingestion (up from 469K in v0.6.0)
• 11.9μs entity query latency
• Clean architecture overhead: <3%

Phase 2: Core Integration Complete

Real-time integration with Core via WebSocket and Broadway:

• CoreWebSocketClient: Real-time event streaming
• ProjectionSync: Automatic state synchronization
• Broadway Pipeline: Production-ready stream processing
• 281 tests passing

v0.2.0 Quality Improvements:

• Race Condition Fix: Fixed ProjectionSync test flakiness by using synchronous call after async cast for proper GenServer message ordering
• Testcontainers Integration: PostgreSQL containers for reliable integration testing

AI-Native Enhancements

Tools designed specifically for AI agent interaction:

• Enhanced Tool Descriptions: Agent guidance embedded
• Query Advice Tool: Intelligent recommendations
• Conversation Context: Multi-turn interaction support
• Quick Exploration: Fast sampling and statistics
• Native Search Tools: Semantic and hybrid search

v0.2.0 Quality Improvements:

• ConversationContext Fix: Made test setup robust by checking for existing GenServer process
• 227 tests passing with 0 failures

Performance Optimizations

• Connection Pooling: Reduced latency for Core communication
• Response Caching: TTL-based caching with Prometheus metrics
• Async Audit Logging: Non-blocking audit writes via channels

• Elixir Test Reporting: New make elixir-test with detailed trace output and failure summaries
• Failed Test Re-runs: make elixir-test-failed to quickly iterate on failures
• Test Watch Mode: make elixir-test-watch for TDD workflow
• Markdown Reports: make elixir-test-report generates test summary reports
• Quality Gates: Enhanced CI failure reporting with log capture

• Native ARM64 runners (no QEMU emulation)
• Registry cache for multi-arch builds
• Optimized container CI pipeline
• Security workflow improvements

• Multi-stage builds for all services
• Published to GitHub Container Registry
• Version badges in README linking to GHCR packages
• Optimized image sizes
• Documentation for all images

• Core test coverage audit
• Query service test quality audit
• Performance benchmark verification
• PostgreSQL integration testing

• Fly.io deployment configuration
• OAuth authentication (Google, GitHub)
• LemonSqueezy billing integration
• Usage metering system
• Subscription enforcement
• API rate limiting
• Customer onboarding flow
