# EU Compliance MCP - Fixes Completed
## Overview
All critical issues identified in the technical review have been fixed and deployed.
---
## Fix #1: Search Query Precision ✅
**Problem:** FTS5 search was too strict - wrapping every word in quotes and using implicit AND logic caused empty results on complex queries.
**Example Failures:**
- "incident reporting notification timeline procedures" → 0 results (required all 5 words)
- "high-risk AI creditworthiness" → 0 results (required all 4 words)
**Solution:** Implemented adaptive search strategy in `src/tools/search.ts`:
- **Short queries (1-3 words):** AND logic with exact matching for precision
- Example: `"incident reporting"` → `"incident" "reporting"` (both required)
- **Long queries (4+ words):** OR logic with prefix matching for recall
- Example: `"incident reporting timeline procedures"` → `incident* OR reporting* OR timeline* OR procedures*`
- BM25 still ranks documents with more matches higher
- **Stopword filtering:** Removes noise words (a, an, the, and, or, etc.)
**Impact:** Dramatically improves recall on complex queries while maintaining precision on simple ones.
---
## Fix #2: EIDAS2 Friendly Name ✅
**Problem:** Articles were stored under CELEX ID `02014R0910-20241018` instead of friendly name `EIDAS2`, causing lookups to fail.
**Root Cause:** Article parsing bug that was preventing sub-articles (5a, 5b, 5c) from being ingested.
**Solution:**
- **User fixed parser bugs** to capture article letter suffixes
- **Database rebuilt** with all 82 EIDAS2 articles now properly indexed under friendly name
- Article 5b "European Digital Identity Wallet-Relying Parties" now accessible
**Verification:**
```bash
sqlite3 data/regulations.db "SELECT id FROM regulations WHERE id = 'EIDAS2'"
# Output: EIDAS2|European Digital Identity Framework (eIDAS 2.0)
sqlite3 data/regulations.db "SELECT COUNT(*) FROM articles WHERE regulation = 'EIDAS2'"
# Output: 82 (was 0 before fix)
```
---
## Fix #3: Tiered Response System ✅
**Problem:** Query "what regulations apply to me?" → 50 pages of detailed requirements → information overload.
**Solution:** Added `detail_level` parameter to `check_applicability` tool with 3 tiers:
### **Tier 1: Summary** (`detail_level='summary'`)
Returns executive overview with:
- Total regulation count
- Breakdown by confidence (definite/likely/possible)
- Priority deadlines for key regulations
- Next steps guidance
**Example Output:**
```json
{
"summary": {
"total_count": 14,
"by_confidence": {
"definite": 9,
"likely": 5,
"possible": 0
},
"regulations_summary": [
{
"id": "DORA",
"full_name": "Digital Operational Resilience Act",
"confidence": "definite",
"priority_deadline": "Jan 17, 2025 (ACTIVE)"
}
],
"next_steps": "For detailed requirements, use detail_level='requirements'..."
}
}
```
### **Tier 2: Requirements** (future enhancement)
Will include key requirements per regulation without full article text.
### **Tier 3: Full** (`detail_level='full'`, default)
Complete details with basis articles, notes, cross-references.
**Tool Schema Updated:**
- `src/tools/applicability.ts` - Added detail_level logic
- `src/tools/registry.ts` - Exposed parameter in tool definition
---
## Fix #4: Evidence Mapping System (Prototype) ✅
**Problem:** Missing "so what" layer - users know requirements but not what artifacts to create for audit evidence.
**Solution:** Created evidence requirements framework:
### **New Database Table:**
```sql
CREATE TABLE evidence_requirements (
id INTEGER PRIMARY KEY,
regulation TEXT NOT NULL,
article TEXT NOT NULL,
requirement_summary TEXT NOT NULL,
evidence_type TEXT NOT NULL, -- document/log/test_result/certification
artifact_name TEXT NOT NULL,
artifact_example TEXT,
description TEXT,
retention_period TEXT,
auditor_questions TEXT, -- JSON array
maturity_levels TEXT, -- JSON object (basic/intermediate/advanced)
cross_references TEXT -- JSON array
);
```
### **Sample Evidence Entry:**
```json
{
"regulation": "DORA",
"article": "6",
"requirement_summary": "ICT risk management framework",
"evidence_type": "document",
"artifact_name": "ICT Risk Management Framework",
"artifact_example": "ICT_Risk_Management_Framework.pdf",
"retention_period": "Duration of operations + 5 years",
"auditor_questions": [
"Show me your documented ICT risk management framework with management board approval",
"How do you define and measure ICT risk tolerance?",
"What is your ICT reference architecture?"
],
"maturity_levels": {
"basic": "Documented ICT risk policy exists",
"intermediate": "Framework integrated with overall risk management, regular reviews",
"advanced": "Continuous improvement, executive KPIs tracked"
},
"cross_references": ["NIS2:21", "GDPR:32"]
}
```
### **Coverage (Initial Prototype):**
- **15 evidence requirements** covering DORA + GDPR + NIS2
- **Key articles:** DORA 6, 11, 17, 19, 24, 28 | GDPR 15, 25, 32, 33 | NIS2 21, 23
### **New Tool:** `get_evidence_requirements`
```typescript
// Get all DORA evidence requirements
get_evidence_requirements({ regulation: "DORA" })
// Get specific article evidence
get_evidence_requirements({ regulation: "DORA", article: "6" })
// Filter by evidence type
get_evidence_requirements({ evidence_type: "test_result" })
```
### **Files Created:**
- `data/seed/evidence/dora-evidence.json` - Prototype data
- `src/tools/evidence.ts` - Tool implementation
- `scripts/build-db.ts` - Updated to load evidence data
- `src/tools/registry.ts` - Tool registration
---
## Implementation Status
| Fix | Status | Files Modified | Impact |
|-----|--------|----------------|--------|
| **#1 Search Precision** | ✅ Complete | `src/tools/search.ts` | High - fixes empty search results |
| **#2 EIDAS2 Fix** | ✅ Complete | Database rebuild, parser fixes | High - enables EIDAS2 queries |
| **#3 Tiered Responses** | ✅ Complete | `src/tools/applicability.ts`, `registry.ts` | Medium - improves UX |
| **#4 Evidence Mapping** | ✅ Prototype | 15 entries for DORA/GDPR/NIS2 | High - new capability |

## Testing Performed
### Search Query Fix
```bash
# Before: 0 results
search_regulations({ query: "incident reporting notification timeline" })
# After: Returns DORA Art 17, 19, NIS2 Art 23, GDPR Art 33 with OR logic
```
### EIDAS2 Fix
```bash
# Before: Article 5b not found in EIDAS2
get_article({ regulation: "EIDAS2", article: "5b" })
# Error: Article 5b not found
# After: Success
# Returns: "European Digital Identity Wallet-Relying Parties"
```
### Tiered Responses
```bash
# Summary view (concise)
check_applicability({
sector: "financial",
subsector: "bank",
detail_level: "summary"
})
# Returns: Executive summary with 14 regulations, priority deadlines
# Full view (comprehensive)
check_applicability({
sector: "financial",
subsector: "bank"
})
# Returns: Complete details with basis articles
```
### Evidence Requirements
```bash
# Get all DORA evidence
get_evidence_requirements({ regulation: "DORA" })
# Returns: 8 evidence items
# Get test results only
get_evidence_requirements({ evidence_type: "test_result" })
# Returns: BCP tests, resilience tests, security tests, etc.
```
