"""
pipeline/batch_500_runner.py
Production Multi-Platform HIFFI Batch Runner.
Production Multi-Platform HIFFI Batch Runner (Hardened 100% Reliability Standards).
Governance Standards Enforced:
- No synthetic proxies or fabricated estimates for Spotify streaming metrics.
- Uncollected metrics are explicitly recorded as NULL (NaN) with provenance tags.
- Spotify API status explicitly logged as BLOCKED_HTTP_403.
- Separation of official Production YouTube HIFFI rank and Experimental HIFFI-XP score.
- Checkpointing enabled with automated resume functionality.
Fixes applied:
1. Low-follower quarantine: Scraped IG < 10,000 without verified override is treated as unverified (NaN),
preventing secondary/fan handles from dragging down veteran artists.
2. Neutral weight scaling: Prevents artists with missing signals from leapfrogging artists with verified data.
3. Strict zero-imputation & provenance tracking preserved.
