 # The Institution suite — master roadmap
 
 A set of RimWorld mods about **what an institution does to the people inside it** — and the crime,
-policing, and justice that put them there. Each mod stands alone; together they form one system.
+policing, and justice that put them there. Each mod is a separate install on a shared **Core**;
+together they form one system.
+
+> **Status (2026-07-15): shipped as a four-mod split.** The monolith split along its seams — the
+> substrate became **Institution: Core** (propensity, criminal record, secured context), the
+> corrections systems became **Institution: Justice** (classification, deterrence, discipline,
+> parole, regime), the gang layer became **Institution: Gangs**, and **Institution: Contraband** is
+> now the physical smuggling loop. **Foul Play** stands alone and bridges in. See the
+> [README](README.md) for the current mod table and dependencies. The design sections further down
+> predate the split in how they *group* modules, but the mechanics and the north star are unchanged;
+> a policing/cops layer (pre-arrest) is where **Justice** grows next.
