Addresses threshold-satisficing behavior where agent declared success
at 91% and moved on. New protocol requires:
- Bulk Phase (90%): Fast progress on tractable errors
- Polish Phase (100%): Triage remaining into categories
- Phase Boundary Rule: Must complete Polish before proceeding
- Documentation: All deferrals documented with rationale
Transforms "78 errors acceptable" into traceable technical decisions.
