- Add initContainer hook to RSC runtime plugin for early server action registration - Change publicPath from hardcoded URLs to 'auto' for dynamic chunk loading - Use only 'rsc' shareScope in server bundles to enforce react-server resolution - Add webpack aliases to force patched react-server-dom-webpack wrappers - Strip NODE_OPTIONS in SSR worker to avoid react-server condition conflicts - Add SharedCounterButton component for shared server actions demo - Import @rsc-demo/shared-rsc in server-entry to register shared actions - Add port cleanup in e2e tests for reliable test runs - Add --conditions=react-server to e2e test server spawns - Add comprehensive test coverage for federation sharing, client refs, cross-app actions, directive transforms, manifests, and shared modules 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
- Use globalThis for server action registry to ensure true singleton across webpack module instances with different IDs - Make getCount async (React requires server actions to be async) - Fix clearAppCaches to preserve registry (actions only register at bundle load) - Update cross-app tests to check relative state changes instead of absolute values - Skip HTTP forwarding tests (require full server runtime) - Fix port handling in HTTP forwarding tests to avoid EADDRINUSE 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Re-enable HTTP forwarding tests - they may fail but should be fixed rather than skipped. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
- use response.text() instead of streaming with getReader() for more reliable response handling in forwardActionToRemote - add warmup request in tests to ensure RSC bundle is fully initialized (handles asyncStartup) - improve port retry logic with new server instance per attempt - preserve original fetch for HTTP forwarding tests All 19 cross-app action tests now pass. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Pushed follow-up commit 4a3e6aa to address the remaining open CodeQL item on packages/enhanced/test/ConfigTestCases.rstest.ts.\n\nThe change removes dynamic wrapper-string construction and executes test bundles through direct VM context wiring to avoid unsanitized code-construction patterns while preserving test harness behavior. |
