## 🎯 Architecture Highlights

### Hexagonal Architecture
- **Pattern**: Ports & Adapters (Alistair Cockburn)
- **Status**: ✅ Validated as HIGHLY SUITABLE
- **Ports**: 7 interfaces (3 primary, 4 secondary)
- **Adapters**: 5 adapters (2 inbound, 3 outbound)
- **Core Domain**: Fully isolated from infrastructure

### Key Design Decisions

1. **Virtual Threads for Scalability** (Req-Arch-6, Req-NFR-1)
   - 1000 concurrent HTTP endpoints
   - Minimal resource usage
   - Java 21+ feature (JEP 444)

2. **Producer-Consumer Pattern** (Req-Arch-7)
   - HTTP polling (producer)
   - gRPC transmission (consumer)
   - Circular buffer (300 or 300000 messages)

3. **Thread-Safe Collections** (Req-Arch-8)
   - ArrayBlockingQueue for buffer
   - ConcurrentHashMap for statistics
   - AtomicLong for counters

4. **gRPC Bidirectional Streaming** (Req-FR-28)
   - Single persistent connection
   - 4MB batch size (Req-FR-30)
   - Max 1s latency (Req-FR-31)

5. **Retry with Linear Backoff** (Req-FR-18)
   - HTTP: 5s → 300s (5s increments)
   - gRPC: 5s interval indefinitely

### Technology Stack
- **Language**: Java 25 (OpenJDK 25)
- **Build**: Maven 3.9+ (fat JAR)
- **RPC**: gRPC Java 1.60+, Protobuf 3.25+
- **Logging**: Java Logging API (100MB × 5 files)
- **Concurrency**: Virtual threads + platform threads
- **Testing**: JUnit 5, Mockito, WireMock, gRPC Testing

- ✅ Producer-Consumer pattern implemented
- ✅ Thread-safe collections used

### Reliability & Error Handling

## ✅ Critical Issues - ALL RESOLVED (2025-11-19)

### 1. Buffer Size Conflict ✅ RESOLVED
- **Original Issue**: Req-FR-26 said "300 messages" but config showed "300000"
- **Stakeholder Decision**: Confirmed as **300 messages**
- **Files Updated**:
  - requirements/HSP_Configuration_File_Specification.md (line 31: 300000 → 300)
  - requirements/DataCollector SRS.md (Req-FR-26 confirmed)
- **Impact**: ~3MB memory usage, well within 4096MB budget
- **Status**: ✅ RESOLVED - Consistent across all documentation

### 2. Duplicate Requirement IDs ✅ RESOLVED
- **Fixed Req-FR-25 duplicate**: Renumbered Req-FR-26 through Req-FR-33
- **Fixed Req-NFR-7, NFR-8 duplicates**: Created new Testing category (Req-Test-1, Req-Test-2)
- **Fixed Req-NFR-9, NFR-10**: Moved to Req-Test-3, Req-Test-4
- **Fixed Req-US-1 (3 instances)**: Renumbered Req-US-1, Req-US-2, Req-US-3
- **Result**: 62 unique requirement IDs (no duplicates)
- **Status**: ✅ RESOLVED - All IDs properly numbered
