+### 2026-06-02: Base Processor Compatibility Runtime Slice
+
+- Status: migrated and root-verified.
+- Completed:
+  - `ts/packages/base/src/processor/async-processor.ts` now uses a
+    `ManagedRuntime` for Promise compatibility methods, signal-shutdown
+    execution, and legacy `AsyncProcessor.launch`.
+  - `ts/packages/base/src/processor/flow.ts` now owns a per-flow
+    `ManagedRuntime` for `start`, `stop`, `runInCompatibilityScope`, and
+    Promise resource facades.
+  - `ts/packages/base/src/processor/flow-processor.ts` now uses a
+    `ManagedRuntime` for the public `start(context)` facade instead of a local
+    `Effect.runPromiseWith` runner.
+  - `ts/packages/base/src/spec/parameter-spec.ts` now routes legacy `add`
+    through `flow.runInCompatibilityScope(...)`, matching the other specs.
+  - Subagent checks confirmed `NodeRuntime` is process-entrypoint-only here;
+    `@trustgraph/base` should not add an `@effect/platform-node` dependency
+    for these compatibility facades.
+- Remaining:
+  - Constructor `as unknown as` shims in base processors preserve
+    callable-plus-newable public exports and are compatibility boundaries for
+    this loop.
+  - Typed string lookup casts in `Flow` need a real typed-spec/key redesign;
+    `HashMap`/`MutableHashMap` alone cannot infer `T` from a bare string.
+- Verification:
+  - `bun run --cwd ts/packages/base build`
+  - `bun run --cwd ts/packages/base test`
+  - `cd ts && bun run check`
+  - `git diff --check`
+  - `cd ts && bun run build`
