+### TypeScript Exemptions (Approved)
+
+The hyperpolymath "no new TypeScript" policy has the following approved exemptions in this repo. These are *not* policy violations — they are documented carve-outs.
+
+| Path | Files | Rationale | Unblock condition |
+|---|---|---|---|
+| `praxis/SymbolicEngine/**/*.ts` | 38 | praxis/SymbolicEngine — GraphQL service + dashboard frontend; depends on Node ecosystem (Apollo, GraphQL.js, Vue/React); migration scoped to a separate AffineScript Node-target + GraphQL-bindings milestone. | AffineScript Node-target codegen (affinescript#35) + GraphQL/Apollo bindings. |
+
+Adding to this list requires explicit user approval and an unblock condition. New TypeScript files outside this list are blocked by the RSR antipattern check.
