Five otherwise-unrelated articles all rest on the same load-bearing precondition: **strategy fails when the data foundation is fragmented or too coarse.**

- **A107** is the purest statement: [[concept-broken-data-foundation]] → "[[quote-broken-intelligence|build intelligence on a broken data foundation and you get broken intelligence, every single time]]". The fix is [[concept-single-instance-data|a single source of truth]] built *before* AI ([[action-fix-data-infrastructure]]).
- **A115** proves the *granularity* corollary: [[claim-broad-data-obscures|zip-code data hides the pattern]]; you need [[concept-block-group-resolution|block-group resolution]].
- **A111** turns 166 variables of workforce data into signal via [[concept-lasso-regression-workforce|LASSO]], separating structure from [[concept-operational-noise]].
- **A117** states it as a slogan — winners "build people-centric businesses by becoming data-centric" ([[prereq-data-infrastructure]]).
- **A109** treats data itself as the priced asset ([[concept-data-mixture-weights]], [[concept-scaling-laws-valuation]]), and warns of [[concept-model-collapse]] if the fresh-data supply dries up.

**The evolution:** A107 says *fix* the data, A115 says *sharpen* it, A111 says *mine* it, A117 says *live* by it, A109 says *pay* for it. Together they make data the invisible spine of the whole tail. Cross-link: [[cross-proprietary-asset-moat]], [[cross-signal-noise-contextual-interpretation]].
