- One test at a time instead of full checklist upfront
- Plain text responses instead of AskUserQuestion forms
- Severity inferred from description, never asked
- Persistent UAT.md survives /clear (like debug workflow)
- Single file per phase replaces per-plan ISSUES.md
- Updated plan-fix to read from UAT.md
