@@ -13,6 +13,19 @@ End-state goal: **full core Datalog** (facts, rules, stratified negation, aggreg
 recursion) with a clean SX query API, and a demonstration of Datalog as a query engine
 for rose-ash data (e.g. federation graph, content relationships).
 
+## Status (rolling)
+
+`bash lib/datalog/conformance.sh` → **208/208 across 11 suites**
+(tokenize, parse, unify, eval, builtins, semi_naive, negation, aggregates,
+api, magic, demo). Source is ~3000 LOC, tests ~2700 LOC, public API
+documented in `lib/datalog/datalog.sx`.
+
+Phases 1–9 are functionally complete; Phase 10 covers the rose-ash
+domain demos (in `lib/datalog/demo.sx`). The PostgreSQL loader and
+`/internal/datalog` HTTP endpoint listed in Phase 10 require service-
+tree edits outside `lib/datalog/**` and are flagged as out-of-scope
+for this loop.
+
 ## Ground rules
 
 - **Scope:** only touch `lib/datalog/**` and `plans/datalog-on-sx.md`. Do **not** edit
