Do not mark Phase 4 complete until the evidence meets the release criteria.
The generated coverage index reports 8.67% statements, 6.81% branches, 13.63% functions, and 8.51% lines. The configured global threshold is 90%. The PR objectives also state that only 41 of 52 integration tests pass. These documents currently report successful 90% coverage, zero blockers, production readiness, and Phase 5 readiness.
