### Appendix C: Methodology

This audit used hallucination-auditor v0.1.0 with public sources only.

**Verification Process**:
1. Text extracted from documents using PyMuPDF
2. Citations resolved to BAILII URLs using pattern matching
3. Authorities fetched and cached with SHA256 content-addressing
4. Claims verified using keyword matching and fuzzy text comparison
5. Errors classified per hallucination-taxonomy

**Public Sources Used**:
- BAILII (British and Irish Legal Information Institute)
- legislation.gov.uk

All evidence is cached locally for reproducibility.

**Audit Statistics**:
- Processing time: <duration>
- Errors encountered: <count>
- Warnings: <count>

Audit completed on <timestamp>.

Report Generation Rules

•Reproducibility: Include all URLs, timestamps, cache paths
•Evidence trails: Every conclusion links to cached artifact
•Conservative language: Use "appears to", "suggests" for MEDIUM/LOW confidence
•No speculation: If UNVERIFIABLE_PUBLIC, say so explicitly
•Summary first: Executive summary gives high-level view
•Details follow: Claim-by-claim breakdown with full evidence
•Appendices: Raw data for full reproducibility
•
Claim outcome aggregation:
- •VERIFIED_CORRECT: All citations for claim are correct
- •VERIFIED_ERROR: At least one citation has error
- •UNVERIFIABLE_PUBLIC: All citations unverifiable
- •MIXED: Some correct, some unverifiable, none errors

Field Requirements

Required for ALL citations:

•citation_id
•citation_text
•resolution_status
•public_gate_outcome
•evidence.retrieval_urls (even if empty list)
•evidence.retrieval_timestamp

Required for VERIFIED_ERROR:

•hallucination_category (must be one of 6 categories)
•confidence (must be HIGH|MEDIUM|LOW)
•evidence.cached_path (if authority retrieved)
•evidence.notes (explanation of error)

Optional fields:

•matching_paragraphs (only if authority parsed successfully)
•verification_outcome (only if verification attempted)
•candidate_urls (only if resolution attempted)

Validation Rules

Before writing reports, validate:

•All VERIFIED_ERROR have hallucination_category
•All VERIFIED_ERROR have evidence.cached_path OR evidence.notes explaining why not
•All outcomes are one of three: VERIFIED_CORRECT, VERIFIED_ERROR, UNVERIFIABLE_PUBLIC
•Summary counts match actual claim/citation tallies
•All timestamps are valid ISO 8601
•All file paths exist in cache/sources
