# Critical Issues - RESOLVED

## Status: ✅ ALL CRITICAL ISSUES RESOLVED

Date Resolved: 2025-11-19

---

## Issue 1: Buffer Size Conflict ✅ RESOLVED

### Original Issue
- **Req-FR-26** stated: "max 300 messages"
- **Configuration Spec** stated: "max_messages: 300000"
- **Impact**: 1000x difference affecting memory and system behavior

### Resolution
**Stakeholder Decision**: Buffer size confirmed as **300 messages**

### Changes Made
1. ✅ Updated `requirements/HSP_Configuration_File_Specification.md` line 31:
   - Changed: `"max_messages": 300000`
   - To: `"max_messages": 300`

2. ✅ Requirement confirmed:
   - **Req-FR-26**: "If gRPC transmission fails, HSP shall buffer collected data in memory (max 300 messages)."

### Impact Assessment
- **Memory Usage**: With 300 messages max @ ~1MB each = ~300MB max buffer
- **System Behavior**: FIFO overflow with 300 message capacity
- **Architecture**: No changes needed, designed for this capacity
- **Status**: Consistent across all documentation

---

## Issue 2: Duplicate Requirement IDs ✅ RESOLVED

### Original Issues

#### 2.1 Req-FR-25 (Duplicate)
- **Line 66**: "HSP shall then send the collected and aggregated data to the CollectorSender Core as decribed below."
- **Line 67**: "If gRPC transmission fails, HSP shall buffer collected data in memory (max 300 messages)."

**Resolution**: Renumbered line 67 and subsequent requirements
- Line 67: Now **Req-FR-26** (buffer 300 messages)
- Line 68: Now **Req-FR-27** (discard oldest) - was Req-FR-26
- Lines 70-75: Renumbered Req-FR-28 through Req-FR-33

#### 2.2 Testing Requirements (Req-NFR-7, Req-NFR-8 duplicates)
- **Lines 117-118**: Duplicate Req-NFR-7 and Req-NFR-8 in Testing Requirements section
- **Lines 119-120**: Req-NFR-9 and Req-NFR-10 also in Testing section

**Resolution**: Created new Testing Requirements category
- **Req-Test-1**: Integration tests shall verify HTTP collection with a mock HTTP server
- **Req-Test-2**: Integration tests shall verify gRPC transmission with a mock gRPC server
- **Req-Test-3**: Tests shall use JUnit 5 and Mockito frameworks
- **Req-Test-4**: All tests shall be executable via 'mvn test' command

#### 2.3 User Stories (Req-US-1 triplicate)
- **Lines 126-128**: All three user stories labeled as Req-US-1

**Resolution**: Renumbered user stories
- **Req-US-1**: System operator story (automatic data collection)
- **Req-US-2**: Data analyst story (reliable gRPC transmission)
- **Req-US-3**: System administrator story (health check monitoring)

## Updated Requirement Count

### Before Fix
- Architecture: 8
- Functional: 32 (with 1 duplicate)
- Non-Functional: 10 (with 2 duplicates in Testing)
- Normative: 6

- **Functional**: 33 (Req-FR-1 to 33) - increased by 1
- **Non-Functional**: 8 (Req-NFR-1 to 8) - reduced by 2
- **Normative**: 6 (Req-Norm-1 to 6)
- **Testing**: 4 (Req-Test-1 to 4) - NEW category
- **User Stories**: 3 (Req-US-1 to 3) - properly numbered
- **Total**: **62 unique requirements** (no duplicates)
