Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change adds structural checks for the package barrel, but some export-removal, source-path, and built-artifact regressions could still go undetected because parts of the test suite can pass without validating the intended condition. The PR is mergeable with explicit owner awareness and follow-up to tighten these bounded checks. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 339-358: Update the overlap test around starReexportSpecifiers and
explicitExports so it fails when any explicit specifier also appears in the star
specifier set. Assert that the overlap is empty, or compare it against a
manifest of intentionally overlapping specifiers, instead of asserting spec is
defined inside the loop.
- Around line 372-396: Update the built-bundle tests around explicitExports and
MESHERY_EXTENSION_CONTRACT_VERSION to iterate over every existing published
artifact, including both DIST_ESM and DIST_CJS, rather than selecting only one.
For each artifact, validate that its actual export declarations contain every
required runtime symbol and the contract version; do not rely on unrestricted
substring matches that can pass for internally referenced names.
- Around line 62-106: Update PINNED_EXPLICIT_EXPORTS and its comparison logic in
indexBarrel.test.ts to track each export’s source specifier, local name, and
exported name, rather than names alone. Populate the entries using the
leaf-module re-exports declared in src/index.tsx, including FeedbackButton from
./custom/Feedback, and compare all three fields so nested barrels cannot satisfy
the test.

Pin the explicit export source with each symbol.
PINNED_EXPLICIT_EXPORTS stores only exported names. If src/index.tsx changes FeedbackButton from ./custom/Feedback to ./custom, this suite can pass when the symbol remains reachable through that nested barrel. That loses the leaf-module declaration workaround that this test is intended to preserve.
Store and compare { specifier, localName, exportedName } entries instead of names alone. The relevant leaf re-exports are established in src/index.tsx lines 20-25.

Make the overlap test assert an expected result.
spec always comes from explicitSpecs, so expect(spec).toBeDefined() always passes. A new direct re-export from a star-re-exported path therefore remains undetected.
Assert that the overlap is empty, or pin the intentional overlapping specifiers in a manifest.

Validate actual exports in every built artifact.
When both artifacts exist, line 374 always reads dist/index.mjs, so dist/index.js is not checked. Also, toContain(name) passes when a name occurs internally without being exported.
Iterate over each existing published artifact and assert its export declarations contain every required runtime symbol and MESHERY_EXTENSION_CONTRACT_VERSION.

Requesting changes because the existing CodeRabbit findings are valid and affect the effectiveness of the regression suite, particularly the no-op overlap assertion and incomplete bundle/export validation.
I also found that the source-symbol check only verifies that an identifier occurs somewhere in the file, rather than confirming it is actually exported. Additionally, the regex-based export parsing has syntax blind spots. These checks should be strengthened before relying on the suite as a structural integrity guard.

Notes for Reviewers
This PR adds a static structural integrity test suite (
src/__testing__/indexBarrel.test.ts) for the root package entry pointsrc/index.tsx.What this test guards against:
export * from './...') and explicit re-exports (export { ... } from './...'). If an export is removed, the test fails and names the exact symbol/specifier missing.from '...'specifiers resolve to actual source files.MESHERY_EXTENSION_CONTRACT_VERSIONappear in the emitteddist/bundle.Signed commits
