+  cherry-picked without conflict as
+  `fd891ff3bb87a29381a0a7006fb4618ec4fe144f`. The merged change set contains
+  exactly six Pi product files and five named Pi tests, with no other Host,
+  Renderer, registry, preview, or P1 path; the source task record remains in
+  its worktree. The source execution's brief shared-worktree incident and
+  interruption were retained accurately; the merger's review and verification
+  were performed serially after takeover.
+- ML-03 owned focused verification:
+  `corepack pnpm exec vitest run tests/unit/pi-resource-loader.test.ts
+  tests/unit/pi-extension-host.test.ts tests/unit/pi-extension-bundle.test.ts
+  tests/unit/pi-worker-process-real.test.ts tests/unit/pi-rpc-foundation.test.ts
+  --maxWorkers=1` — 5 files / 43 passed / 2 skipped (Vitest 7.65s; the skips
+  are staged-runtime gated).
+- All Pi regressions:
+  `pi-*.test.ts` — 30 files / 169 passed / 2 skipped (Vitest 19.34s, one
+  worker).
+- `corepack pnpm run typecheck` — passed. `corepack pnpm run lint:check` —
+  passed with 0 errors and the same 5 pre-existing warnings in
+  `src/pages/Home/index.tsx` and `src/pages/Makelore/index.tsx`.
+- `corepack pnpm run build:vite` — passed for Renderer, Main, Preload, and
+  utility bundles; only existing dynamic-import/chunk-size warnings were
+  emitted. The ML-03 changed files contain no static Data Service worker list;
+  dynamic declarations, bridge allowlisting, CLI agreement, child-empty
+  exposure, disabled/re-enabled assignment, and old-worker behavior are
+  covered by the owned focused suite. `git diff --check` passed.
 
 ## Follow-ups
 
-- ML-03 may consume the policy/capability registry, bounded capability envelope,
-  Data Service adapter, and Pi product-tool delegation from exact product
-  frontier `a0361a3cda08ab4d7454d35caa56a5a4304a9dca`.
+- ML-04 may consume the effective plugin worker-resource snapshot, dynamic Pi
+  declarations/bridge/CLI materialization, and child-empty behavior from exact
+  product frontier `fd891ff3bb87a29381a0a7006fb4618ec4fe144f`; ML-04 owns its
+  Host/Renderer composition changes.
 - The legacy `resources/coding-skills/data-service` path is intentionally removed
   by ML-01; any unowned downstream reference must be migrated by its owning
   ticket. This merger made no such downstream edit.
