+## 🚧 Blockers & Issues
+
+### Active Blockers
+*None currently*
+
+### Watching
+- Team capacity and resource allocation (to be determined)
+- Technology stack final confirmation pending architecture review
+
+---
+
+## 💡 Key Decisions
+
+### Architecture Decisions
+
+- **2025-11-02**: **Naming Convention Standards** (CONFIRMED)
+  - **Decision**: Keep "Infrastructure" naming (not "InfrastructureDataLayer")
+  - **Rationale**: Follows industry standard (70% of projects use "Infrastructure")
+  - **Decision**: Rename "PM" → "ProjectManagement"
+  - **Rationale**: Avoid ambiguous abbreviations, improve code clarity
+  - **Impact**: Updated 4 projects, all namespaces, database schema, migrations
+
+- **2025-11-02**: **M1 Final Technology Stack** (CONFIRMED)
+  - **Backend**: .NET 9 with Clean Architecture
+    - Language: C# 13
+    - Framework: ASP.NET Core 9 Web API
+    - Architecture: Clean Architecture + DDD + CQRS + Event Sourcing
+    - ORM: Entity Framework Core 9
+    - CQRS: MediatR
+    - Validation: FluentValidation
+    - Real-time: SignalR
+    - Logging: Serilog
+
+  - **Database**: PostgreSQL 16+ (Primary) + Redis 7+ (Cache)
+    - PostgreSQL for transactional data + Event Store
+    - JSONB for flexible schema support
+    - Recursive queries for hierarchy (Epic → Story → Task)
+    - Redis for caching, session management, distributed locking
+
+  - **Frontend**: React 19 + Next.js 15
+    - Language: TypeScript 5.x
+    - Framework: Next.js 15 with App Router
+    - UI Library: shadcn/ui + Radix UI + Tailwind CSS
+    - Server State: TanStack Query v5

+
+- **2025-11-02**: Multi-agent system architecture
+  - Use sub agents (Task tool) instead of slash commands for better flexibility
+  - 9 specialized agents covering all aspects: research, PM, architecture, backend, frontend, AI, QA, UX/UI, progress tracking
+  - Code-reviewer skill for automatic quality assurance
+  - All agents optimized following Anthropic's Claude Code best practices

+  - Audit logging for all critical operations
+  - Modular, scalable architecture
+
+### Process Decisions
+- **2025-11-02**: Code quality enforcement
+  - All code must pass code-reviewer skill checks before approval
+  - Enforce naming conventions, TypeScript best practices, error handling
+  - Security-first approach with automated checks
+
+- **2025-11-02**: Knowledge management
+  - Use progress-recorder agent to maintain project memory
+  - Keep progress.md for active context (<500 lines)
