Fix entire feature systematically

systematically repair entire feature/module in 5 phases

Deep repair of a broken module with strict phase discipline and evidence-based diagnosis.

• · feature-path argument
• · engineering/focused-fix/SKILL.md workflow

• · scope map, dependency trace, diagnostics, fixes, verification

• · code analysis
• · test runner
• · bash

• · feature path is valid
• · SKILL.md workflow exists

• · skipping Phase 3 diagnostics
• · fix cascade (>3 fixes)
• · scope not bounded
• · consumer tests not verified

• · enforces all 5 phases in order
• · no fixes before Phase 3 diagnostics
• · 3-strike escalation for cascading fixes
