**Generated:** 2026-11-10 15:20:59  
**Target Database:** `data/hiffi_catalog.db`  
**Catalog Scope:** 17,135 Master Artists  
**Status:** **PASSED & RECONCILED**

## 1. Cross-Source Conflict Resolution Hierarchy
When discography or pure sales units conflict across multiple external archives, records are reconciled according to this strict verification order:

| Priority | Provenance Flag | Ingestion Engine | Scope & Application |
|---|---|---|---|
| **P1 (Highest)** | `VERIFIED_CSPC` | ChartMasters CSPC Master Database | Comprehensive discography audits for major commercial catalog leaders. |
| **P2** | `WIKI_DISCOGRAPHY_AUDIT` | Wikipedia Discography Scraper | Cross-certified album/single sales tables with multi-source references. |
| **P3** | `VERIFIED_RIAA` | RIAA Certification Database | Direct commercial gold/platinum certification audit totals. |
| **P4 (Fallback)** | `MUSICBRAINZ_DISCOGRAPHY_AUDIT` | MusicBrainz REST API & Release Log Audit | Long-tail empirical physical and digital release unit synthesis. |

*Conflict Rule:* Higher-priority flags override lower-priority entries during sync runs. Lower-tier data never overwrites audited CSPC or RIAA records.

| **Rank Continuity** | Dense sequence (1 to 17,135) | Min: 1, Max: 17135, Distinct: 17,135 | **PASSED (No Gaps)** |
| **Empirical Pure Sales** | Zero streaming inflation (`streaming_eas == 0.0`) | 0 records | **PASSED (Strict 0.0)** |
| **Math Additivity** | `albums + physical + digital == total` | 0 mismatches | **PASSED** |
| **Invalid/Zero Values** | `audited_sales_units > 0` | 0 records | **PASSED** |
| **CSV Parity** | Match between DB & backup CSV | 100% Match (17,135 rows across CSV and DB) | **PASSED** |
