The corpus mounts a coordinated attack on **surface metrics that measure a first touch instead of a durable relationship.**

- **A007:** stop optimizing signups; optimize the [[concept-re-completion-rate]] — the *second* transaction within a task's natural window ([[action-optimize-second-transaction]]). OpenAI's Instant Checkout allegedly failed by winning the first transaction ([[claim-instant-checkout-failure]]).
- **A071:** abandon [[concept-vanity-metrics]] (impressions, basic CTR) for [[concept-performance-accountability|incremental sales]] linked exposure-to-transaction ([[action-link-ads-to-transactions]]); suppliers charged on vanity metrics call RMNs a '[[quote-black-box-with-a-bill|black box with a bill]]'.
- **A065:** replace reach counts with [[concept-connectedness|mutuality]] — reciprocal engagement, not likes/followers; 'statues end up in museums' ([[quote-statues-in-museums]]).
- **A070:** the true cost the captive model ignores is the *disengaged viewer* who churns ([[claim-captive-model-churn]]) — a lifetime-value metric, not an impression count.

The convergent claim: **the metric that mattered in the attention economy (the first impression/click/signup) is exactly the metric that lies in the relationship economy.** Each article proposes a durability metric — re-completion, incrementality, mutuality, retention — that indexes whether the customer *comes back*. This is the measurement layer of [[cross-trust-the-new-moat]].
