🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Cover the candidate-continuation path.
This fixture contains only Unrelated. It verifies fallback to the original bytecode, but it does not verify that a valid candidate after the malformed candidate is selected. Add a valid candidate after Unrelated and assert that getUnlinkedBytecode returns that candidate's unlinked bytecode. This covers the loop behavior in packages/core/src/validate/query.ts, Lines 133-140.

Summary
Fix
getUnlinkedBytecode()when validation data contains unrelated library-linked contracts.The function now skips candidates whose link references produce invalid bytecode, then continues checking other candidates or returns the original bytecode. This prevents unrelated library references from breaking deployments of contracts without libraries.
Tests
Added a regression test for invalid unrelated link references.
git diff --checkpasses.The local AVA and TypeScript binaries were unavailable after dependency installation was blocked by filesystem inode exhaustion.
