From d342f145fec60dc778e65ee7aa1d257ffd492c94 Mon Sep 17 00:00:00 2001 From: PushNaNaShi <84632330+pushnanashi2@users.noreply.github.com> Date: Mon, 7 Sep 2026 01:55:58 +0900 Subject: [PATCH 1/9] fix: close fourteen analysis and governance regressions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Problem: Boundary checks could miss public API changes, loader origins, URL authorities, overflowed alternatives and supported routes. Ownership, coverage and Python dependency reporting could disagree with runtime behavior. Change: Fix the fourteen reviewed cases (#48–#61), add regression tests with Node and Python oracles, and correct baseline adoption documentation. Behavior: Known references resolve from their actual origin; unsupported loader flow and incomplete resource analysis fail closed. Explicit head refs analyze committed snapshots. Ownership and coverage use consistent exclusions and directory semantics. Tests: Full test suite: 1,182 passed, 2 skipped, 0 failed. Build, lint and typecheck passed. Scoped mutation is running. Known-Gaps: Self-check requires review and re-signing of the accepted engine baseline after correcting public API hashing. The signed baseline and verification policy are preserved. Mutation verification is pending. Change-Type: implementation Changed-Cells: cli,engine,plugin-blast-radius Tests-Added: tests/bug-fixtures.mjs Tests-Modified: tests/module-resolution.test.mjs,tests/official-plugins.test.mjs,tests/resource-access-coverage.test.mjs,tests/review-regressions.test.mjs Test-Impact: Regression tests cover all fourteen reviewed cases with runtime resolution oracles where applicable. Tests-Not-Added-Reason: Regression tests were added for all reviewed cases.

Loader regression coverage needed direct factory, bound alias and exact fail-closed diagnostics. Change: Remove the redundant URL argument fallback and add focused regression cases for URL failures and loader origins, preserving concurrent regression fixes. Behavior: Malformed or overflowing URL alternatives cannot produce a partially approved result. Supported loader origins remain precise and unsupported loader flows report stable diagnostics. Tests: The latest 131 targeted tests, build and signed-baseline self-check pass. Resource-access mutation scored 100% in a forced full scope run. Module-resolution mutation is still running. Known-Gaps: The remaining module-resolution mutation result and latest cross-platform CI are pending. Change-Type: implementation Changed-Cells: engine Tests-Added: none Tests-Modified: tests/module-resolution.test.mjs,tests/resource-access-coverage.test.mjs Test-Impact: Cover malformed URL alternatives, URL Cartesian overflow, direct createRequire calls, bound aliases, and exact unsupported-loader diagnostics.
