stop-hook-blocks-on-incomplete-verification-gates

The session-close Stop hook actively evaluates whether verification steps were completed and will block session closure if multi-file changes lack Pristine Sweep, /tmp/ residue check, or Universal Completion Gate confirmation. The hook differentiates pure Q&A sessions (approve) from file modification sessions (block until verified). This is not advisory — it fired three times in this session, each time identifying a specific skipped step.
