+
+**Goal:** The 18 beach-named framework packages live under `modules/<name>/` with the same names and a single root `go.mod`; importers in summercms.go, examples, and fonoteka.go use `git.golem15.com/golem15/summercms/modules/<name>`; each module has a short README; the root README is honest run/onboarding docs.

 ### Phase 11: Jobs, realtime and search infrastructure
 
 **Goal**: River jobs run on the correct dual-driver split, Centrifugo publishing and channel authorization match the existing server, and Typesense sync stays a re-gated pre-filter — all brought up before the API phases that depend on them (album search needs Typesense sync, CSV import needs River jobs, notifications need the realtime publisher). River's dual-driver split and the Centrifugo/Typesense contracts are the least-implemented-and-verified parts of this research pass.
