+### 2026-06-02: Client Newable Factory Compatibility Decision
+
+- Status: documented no-op for the current loop.
+- Evidence:
+  - `ts/packages/workbench/src/atoms/workbench.ts` constructs
+    `new BaseApi(...)`.
+  - `ts/packages/client/src/__tests__/flows-api.test.ts` constructs
+    `new FlowsApi(...)`, and sibling API facades expose the same constructor
+    shape.
+  - `EffectRpcClient` and `BaseApi` also preserve callable factory exports for
+    compatibility with the vendored TrustGraph client shape.
+- Decision:
+  - The remaining `newableFactory(... ) as unknown as NewableFactory<...>`
+    assertions in client socket files are TypeScript compatibility boundaries,
+    not Effect error/requirement channel assertions and not replacements for an
+    Effect primitive.
+  - Removing them safely requires a deliberate public API redesign or explicit
+    class implementations for every API facade, not a local Effect-native
+    rewrite.
+- Verification:
+  - Current client/root verification from the tagged error slice covers this
+    no-op decision.

-  - `effect/unstable/rpc/RpcSerialization.layerNdjson` or `layerNdJsonRpc`.
-  - `ManagedRuntime` for compatibility facades when a Promise API must remain.
-- Rewrite shape:
-  - `EffectRpcClient` is now an internal managed runtime with Promise
-    compatibility facades.
-  - Expose Promise-returning methods through a thin adapter.
-  - Replace remaining client newable factory assertions with a typed factory
-    shape that preserves current constructor/function compatibility.
