Triage Result

Priority: P2 (Medium — minor bug, workaround exists by avoiding double-optimize)
Component: build / optimizer
Assigned: @xieofxie (reporter, familiar with the root cause from PR #1058)

Summary: Double optimization during Qwen build causes a crash. Root cause was identified and reverted in PR #1058. Needs a proper fix.

Next steps: Investigate the optimization state management to prevent re-entry or guard against double-invoke.
