Multi-Platform Spend Anomaly Detection

Extend spend anomaly detection across all platforms. Detect cross-platform anomalies: sudden CPM spikes on Meta correlating with increased competition from Google advertisers in the same vertical.

Features:

• Per-platform anomaly baselines
• Cross-platform correlation detection (Meta CPM spike + Google CPC spike = market shift)
• Platform-specific alerts with recommended actions
• Historical anomaly timeline across all platforms

Impact: Market-level intelligence from cross-platform data that no single-platform tool can provide.
