## 1. Use-Case Identifier and Name

**ID:** UC-RF-004
**Name:** Integrate Citations into Documentation with Claims Backing

## 2. Scope and Level

**Scope:** AIWG Research Framework - Integration Stage
**Level:** User Goal
**System Boundary:** Citation Agent, Claims Index, Bibliography Generator, .aiwg/requirements/, .aiwg/architecture/

## 3. Primary Actor(s)

**Primary Actors:**
- Developer-Researcher: Needs to back architecture decisions with research citations
- Documentation Specialist: Adding citations to SDLC documents (requirements, ADRs)
- Academic Researcher: Building bibliography for systematic review paper

**Actor Goals:**
- Back claims with citations automatically
- Format citations in any of 9,000+ styles (Chicago, APA, IEEE, etc.)
- Generate bibliography for documentation or publications
- Build citation network showing paper relationships
- Track which claims have backing and which need research

## 4. Stakeholders and Interests

| Stakeholder | Interest |
|------------|----------|
| Developer-Researcher | Fast citation insertion, architecture docs credible |
| Documentation Specialist | 100% claim coverage, citation accuracy >95% |
| Academic Researcher | BibTeX/RIS export, citation network visualization |
| Framework Maintainer | Integration with SDLC docs, citation style flexibility |

## 5. Preconditions

1. UC-RF-003 completed: Papers documented with summaries and extractions
2. `.aiwg/research/knowledge/` contains literature notes and summaries
3. SDLC documents exist (requirements, architecture) with claims needing backing
4. Claims index initialized in `.aiwg/research/knowledge/claims-index.md`
5. User has selected citation style (default: Chicago 17th)

## 6. Postconditions

**Success:**
- Claims backed with formatted citations in SDLC documents
- Claims index updated showing 100% coverage (all claims backed)
- Bibliography generated in `.aiwg/research/bibliography.md`
- BibTeX/RIS export available for external tools (Zotero, LaTeX)
- Citation network graph created showing paper relationships
- User satisfied with citation accuracy (>95%)

**Failure:**
- Citation integration aborted with error message
- No partial edits (transactional: documents unchanged on error)
- Failed citations logged for manual resolution
- User can retry or add citations manually

## 7. Trigger

User runs citation command: `aiwg research cite "Token rotation reduces CSRF risk" --source REF-025`

Alternative triggers:
- Bulk citation: `aiwg research cite --auto-back-claims`
- Natural language: "Add citations to architecture document"
- Slash command: `/research-cite --document .aiwg/architecture/software-architecture-doc.md`

## 8. Main Success Scenario

1. User runs citation command with claim and source (REF-XXX)
2. Citation Agent validates inputs:
   - Checks REF-XXX exists in `.aiwg/research/sources/metadata/`
   - Verifies claim is string (not empty)
   - Checks citation style configured (default: Chicago 17th)
3. Agent retrieves source metadata:
   - Loads `.aiwg/research/sources/metadata/{REF-XXX}-metadata.json`
   - Extracts: Title, authors, year, venue, DOI, URL
   - Validates metadata completeness (warns if missing fields)
4. Agent formats citation in selected style:
   - Uses CSL (Citation Style Language) templates
   - Generates inline citation: `(Smith and Doe 2023)`
   - Generates full citation: `Smith, John, and Jane Doe. 2023. "OAuth 2.0 Security Best Practices." In Proceedings of ACM CCS, 123–145. https://doi.org/10.1145/example.`
5. Agent locates claim in SDLC documents:
   - Scans `.aiwg/requirements/`, `.aiwg/architecture/` for claim text
   - Matches exact string or semantic similarity (>90% match)
   - Prompts user if multiple matches: "Found in 3 files. Apply to all? (y/n/select)"
6. Agent inserts citation in document:
   - Appends inline citation after claim: `Token rotation reduces CSRF risk by 80% (Smith and Doe 2023).`
   - Adds reference to bibliography section if not present
   - Preserves document formatting (Markdown structure intact)
7. Agent updates claims index:
   - Marks claim as "backed" in `.aiwg/research/knowledge/claims-index.md`
   - Logs citation: Claim → REF-XXX → Document location
   - Updates coverage percentage: `Claims backed: 150/200 (75%)`
8. Agent builds citation network edge:
   - Creates relationship: Document → REF-025 (cites)
   - Updates citation network graph in `.aiwg/research/networks/citation-network.json`
   - Tracks citation context: Supported (claim agrees with source) vs. Contradicted
9. Agent generates/updates bibliography:
   - Adds full citation to `.aiwg/research/bibliography.md`
   - Sorts bibliography alphabetically by author
   - Deduplicates entries (same source cited multiple times)
10. Agent validates citation accuracy:
    - Checks all citation fields populated (no "Unknown Author")
    - Verifies DOI link resolves (HTTP 200 response)
    - Warns if citation incomplete: "Missing venue for REF-025"
11. Agent saves citation record:
    - Logs citation insertion in provenance log (UC-RF-005)
    - Records timestamp, user, document, claim, source
    - Enables undo: `aiwg research cite --undo last`
12. Agent displays success message:
    - "Citation added: 'Token rotation reduces CSRF risk' → REF-025 (Smith and Doe 2023)"
    - "Claims backed: 151/200 (75.5%)"
    - "Bibliography updated: .aiwg/research/bibliography.md"
13. User reviews citation in document:
    - Opens document: `.aiwg/architecture/software-architecture-doc.md`
    - Verifies citation formatted correctly
    - Checks bibliography entry complete
14. User continues adding citations or proceeds to next workflow

## 9. Alternate Flows

### Alt-1: Auto-Back Claims (Bulk Citation)

**Branch Point:** Step 1
**Condition:** User wants to automatically back all unbacked claims

**Flow:**
1. User runs: `aiwg research cite --auto-back-claims`
2. Agent scans claims index for unbacked claims (50 claims)
3. Agent matches claims to literature notes via semantic search:
   - Claim: "LLM caching reduces latency by 40%"
   - Match: REF-042 summary contains "40% latency reduction via semantic caching"
   - Confidence: 95% (high match)
4. Agent prompts for each match: "Back claim with REF-042? (y/n/skip)"
5. User approves high-confidence matches (>90%), skips low-confidence
6. Agent inserts citations for approved matches (30 claims backed)
7. Agent displays summary: "Backed 30/50 claims automatically. 20 require manual review."
8. **Resume Main:** Step 8 (Agent updates claims index)

## 11. Special Requirements

### Performance Requirements

| Requirement | Target | Rationale |
|------------|--------|-----------|
| NFR-RF-C-01: Citation formatting time | <5 seconds per citation | User experience |
| NFR-RF-C-02: Bulk citation throughput | 10 claims/minute | Efficiency |
| NFR-RF-C-03: Bibliography generation time | <10 seconds for 100 entries | Usability |

### Quality Requirements

| Requirement | Target | Rationale |
|------------|--------|-----------|
| NFR-RF-C-04: Citation accuracy | >95% (validated against CSL spec) | Reliability |
| NFR-RF-C-05: Claim matching precision | >90% (semantic similarity) | Reduces false positives |
| NFR-RF-C-06: DOI link validity | >95% resolve successfully | Trust |

### Usability Requirements

| Requirement | Target | Rationale |
|------------|--------|-----------|
| NFR-RF-C-07: Citation style coverage | 9,000+ styles (via CSL repository) | Flexibility |
| NFR-RF-C-08: Claims index visibility | Real-time coverage percentage | User awareness |

## 12. Related Business Rules

**BR-RF-C-001: Citation Style Hierarchy**
- Default: Chicago 17th (author-date)
- Common alternatives: APA 7th, IEEE, MLA 9th, Harvard
- Custom: User-provided CSL file (validated against CSL schema)

**BR-RF-C-002: Claims Index Schema**
- Claim text (string)
- Status: Backed (has citation) | Unbacked (needs research)
- Source: REF-XXX if backed
- Document location: File path + line number
- Last updated: Timestamp

**BR-RF-C-003: Citation Network Context**
- **Supported:** Claim agrees with source (default assumption)
- **Contradicted:** Claim disagrees with source (user-marked)
- **Uncertain:** Relationship unclear (requires expert judgment)

**BR-RF-C-004: Bibliography Sorting**
- Primary sort: Author last name (alphabetical)
- Secondary sort: Year (descending for same author)
- Deduplication: Same DOI = same source (merge duplicates)

- Citation formatting (multiple styles) → UC-RF-004 Step 4
- Claims index automation → UC-RF-004 Step 7
- BibTeX/RIS export → UC-RF-004 Alt-2
- Citation backing for SDLC docs → UC-RF-004 Step 6

### Risk Mapping

**T-05: Citation Accuracy (Medium Priority):**
- Mitigated by: CSL validation (Step 4), DOI link checking (Step 10), metadata completeness warnings (Exc-1)
- Monitored via: Citation accuracy rate (NFR-RF-C-04), user-reported errors
