stop-hook-blocks-mid-brainstorm-workflow-correctly

The Stop hook correctly distinguishes ‘pure Q&A/research with no file changes’ (APPROVE) from ‘active brainstorming workflow awaiting section-by-section user validation’ (BLOCK). A session at Step 4 of 9 in the brainstorming skill with user feedback pending will loop on stop attempts indefinitely until the user provides feedback. This is correct behavior but creates a UX loop if user goes idle mid-session without responding to a section review prompt.
