Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to The change adds configurable server-side package externalization and cache partitioning, but configured packages can still cause app-router loading or error components to fail, and a cache-isolation test is deterministically broken. Merge should be blocked until these correctness and test-integrity issues are fixed. Sequence Diagram(s)sequenceDiagram

In `@src/rendering/layouts/utils/component-loader.test.ts`:
- Around line 716-722: Update the common arguments used by the loadTSXComponent
test so they do not include the trailing undefined serverExternalPackages value;
ensure the package arrays passed in the two loadTSXComponent calls occupy that
supported argument position and the cache-key assertion compares distinct
package sets.
In `@src/server/services/rsc/orchestrators/handler.test.ts`:
- Around line 49-50: Replace the expect-based assertions for
moduleOptions.isLocalProject and moduleOptions.serverExternalPackages with
assertEquals imported from `#veryfront/testing/assert.ts`, preserving the existing
expected values.
In `@src/transforms/mdx/esm-module-loader/module-writer.ts`:
- Around line 282-288: Update the root dependency rewriting flow around
cacheHttpImports to include effectiveContext.serverExternalPackages in
MdxRootDependencyRewriteOptions, ensuring configured server externals such as
knex and `@prisma/client` are preserved before HTTP caching. Add coverage
verifying both packages remain external during root rewriting.
In `@src/transforms/shared/server-only-packages.test.ts`:
- Around line 14-20: Replace the Deno.test registration in server-only package
tests with describe() and it() imported from `#veryfront/testing/bdd.ts`,
preserving the existing assertions and coverage for configured package names
across runtimes.
Apply the same fix in `@src/modules/server/module-server.test.ts` around lines
2098 - 2127: The same cross-runtime test portability issue occurs in the
filesystem setup and cleanup calls.
