+feat(create-expert): Add Integration Manager for coordinated testing
+
+- Add integration-manager that coordinates functional and usability testing in parallel
+- Consolidate happy-path-manager, unhappy-path-manager, adversarial-manager into functional-manager
+- Simplified workflow: create-expert → property-extractor → ecosystem-builder → integration-manager → report-generator
+- Integration manager provides:
+  - Parallel execution of functional and usability tests
+  - Trade-off analysis (security vs usability)
+  - Integration verification (ecosystem experts work together)
+  - Holistic quality assessment with combined scoring
+
+Closes #339

 ## Important
 - Pass context between delegates (properties, test results, ecosystem info)
-- Each manager handles its own PDCA loop
-- You just orchestrate the flow
+- Integration manager coordinates both functional and usability testing
+- You just orchestrate the high-level flow
 - The ecosystem should be immediately usable by fresh users

+Delegate to both managers simultaneously:

+Identify any conflicts between functional and usability requirements:
+- Security vs ease-of-use (e.g., strict validation vs auto-correction)
+- Performance vs features
+- Complexity vs usability
+
+### 4. Integration Verification
+Verify ecosystem experts work together:
+- Setup expert properly configures for main expert
+- Doctor expert correctly diagnoses main expert issues
+- Demo expert accurately represents main expert capabilities
+
+### 5. Holistic Assessment
+Calculate overall quality score:
+- Functional score (happy/unhappy/adversarial combined)
+- Usability score (demo/setup/doctor/error-guidance combined)
+- Integration score (ecosystem coherence)
