 - Core filesystem and git error paths now wrap underlying failures with command-specific context across listing, generation, tracking, linking, rc hook execution, and destroy confirmation flows.
 - Gosec compliance updated for intentional command execution paths: `Open()` now documents both `G702` and `G204` suppression rationale, and fixed-`git` helper invocations include explicit `G204` justifications.
 - PR validation badge upload now runs only when `coverage.out` exists, preventing downstream badge artefact failures while still allowing PR decoration to run on failed jobs.
+- PR validation now keys coverage badge upload off the coverage step outcome and performs changelog gate validation in a native workflow step; decorate-pr changelog gating is disabled to bypass the broken internal extractor action.
 - README badge link target updated to `actions/runs/latest?workflow=...` format per workflow standards.
 - CI security scanning now uses GitHub Marketplace actions (`securego/gosec` and `golang/govulncheck-action`) instead of manual tool installation, improving reliability and caching.
 - CI setup compatibility fix: gosec scanner now references the correct public action source (`securego/gosec`), resolving action clone failures in Gitea runners.
