How it works
Each path gets a weighted score across real net value, speed of value, merchant trust, complexity, and confidence. Promotions with 36 months of bill credits can still win, but only when the math does.
01
Devices, merchants, offers, buy sources, and raw ingest rows are modeled separately so the data layer stays sane as ingestion expands.
02
Bill credits, line requirements, premium-plan lock-in, and acquisition risk all reduce headline value before ranking.
03
The top path exposes the biggest caveat, confidence score, timestamps, and direct source CTAs so the recommendation remains auditable.
Weighted comparison across the current top ranked upgrade paths.

Best paths
The engine exposes the tradeoff instead of hiding it.
Real net value
AT&T still wins after subtracting delay, plan lock-in, and expected friction.
Confidence
The path combines merchant trust and verification into a 59 confidence score.
Caveat
36-month bill credits delay value realization.
Acquisition and redemption links use an affiliate-ready abstraction that supports direct links, referral links, and future tracking parameters. No merchant appears higher just because it monetizes better.
Buy-first scenarios keep direct and affiliate acquisition links separate so monetization can expand without changing ranking logic.
Trade-in or upgrade CTAs can route to carrier, retailer, or OEM checkout pages with future tracking parameters added at the edge.
When no affiliate program exists, the app still exposes a clean direct CTA and marks the merchant normally in the ranking engine.
