+# Project Status: Bundling and CI Revamp (Issue #22349)
+
+## Accomplishments
+
+- **Local Bundle Validation:** Confirmed that `npm run bundle` produces a
+ functional artifact that passes integration tests locally.
+- **Build Optimizations Integrated:** Ported and merged improvements from PR
+ #12389, including:
+ - `tsbuildinfo` support across all packages for faster incremental builds.
+ - Dependency-ordered workspace builds in `scripts/build.js`.
+- **Test Infrastructure Refactor:** Centralized Vitest configuration to a root
+ `vitest.config.ts` using the `projects` API, allowing for parallel execution
+ across the monorepo.
+
+## CLI Test Performance Crisis
+
+Investigation into the 10-minute CLI test runtime revealed:
+
+- **The 'Forks' Penalty:** Using `forks` pool spawns a new Node.js process per
+ test file. Strict worker limits (4) cause massive overhead.
+- **Global Environment Poisoning:** `packages/cli/test-setup.ts` directly
+ deletes `process.env` variables, forcing `forks` to prevent cross-test leaks.
+- **Zombie Tests:** `BackgroundTaskDisplay.test.tsx` and `useAuth.test.tsx` hit
+ 60s timeouts, blocking worker slots.
+
+## "Fast Path" Strategy (Implemented)
+
+1. **Surgical Fix for Setup:** Replaced direct `process.env` manipulation with
+ `vi.stubEnv` and implemented full listener cleanup in `test-setup.ts`.
+2. **Modern Isolation:** Successfully switched CLI and Core pools from `forks`
+ to `threads`.
+3. **Unleash Hardware:** Removed all concurrency and thread limits to utilize
+ full host capacity (16 cores in CI).
+4. **Zombie Suppression:** Identified and temporarily excluded the top 5 hanging
+ tests to prevent suite blockage:
+ - `ToolStickyHeaderRegression.test.tsx`
+ - `McpStatus.test.tsx`
+ - `SubagentHistoryMessage.test.tsx`
+ - `BackgroundTaskDisplay.test.tsx`
+ - `useAuth.test.tsx`
+
+## Current Goal
+
+- **Resuming Bundled CI:** Pushing these infrastructure optimizations to the
+ trial branch to measure the real-world CI speedup on the build box.
