Summary

• Validate every declared precondition callback before replacing a scope binding; an invalid update leaves the prior binding live.
• Add a regression that failed on the old behavior and now checks the PRECONDITION error and preserved handler.
• Prepare the matching 1.0.2 package set because 1.0.1 is already published. Published 1.0.1 installation links remain accurate until the patch release.

Local verification

• Red before fix: focused test failed with Missing expected exception.
• Exact pnpm 10.17.1 frozen install and build passed.
• Synthetic Node suite: 27/27 passed on Windows.
• Six tarballs packed; package and production-bundle audit: 8/8 passed.
• Disposable installed-package smoke: CLI reports 1.0.2 and runtime rejects the missing callback while preserving the original binding.

CI runs the isolated Chromium fixture lanes and package consumer on Windows and Ubuntu. No user data or live provider was used locally.
