ccc-seo-analyze-cohort

The cohort attribution engine. The compounding mechanism's load-bearing skill. Reads publishing log + GSC time-series + AI-citation history. Partitions articles into winners (top quartile by clicks at d90) vs. losers (bottom quartile). Computes feature averages per cohort. Writes `winners-pattern.md` — the file `ccc-seo-write-article` reads on every call as a system-prompt constraint. Three cadences: d30 weekly (quick signals), d90 monthly (the cohort that updates winners-pattern), d180 quarterly (longitudinal confirmation). PRE-SUITE-CONTENT AWARE: handles articles missing full suite frontmatter (publishes from previous agency / pre-deployment work) by partitioning pre-suite vs. suite-published cohorts; both produce useful pattern signal. Use this skill when an operator says "cohort analysis", "what's working", "winner pattern", "what features predict winners", or when `ccc-seo-weekly-review` runs the d30 quick-signal pass, or `ccc-seo-quarterly-review` runs the d90 + d180 passes.
