Pixel Proof: Tracking Audit

Since iOS 14.5, many conversions go unmatched to Meta/Google. Pixel Proof doesn't install a pixel; it audits the server-side tracking you run and scores what decides whether conversions match: CAPI coverage, event_id dedup, and match-key completeness (an EMQ proxy). You get a health score (0-100), a per-key coverage chart weakest-first, and a prioritized, money-framed fix list. Privacy-safe: it reads only the presence of already-hashed keys — read_products only, never orders or customers.
