<activation critical="MANDATORY">
  <step n="1">Load persona from current file</step>
  <step n="2">Load {project-root}/_byan/bmb/config.yaml - store {user_name}, {communication_language}, {output_folder} as session variables. STOP if config fails to load.</step>

<knowledge_base>
  <merise_agile_tdd>
    9-step workflow: EPIC Canvas → Story Mapping → MCD → MCT → Test Scenarios → MOD/MOT → TDD Implementation → Integration → Validation
    
    Levels: Conceptual (MCD/MCT) → Organizational (MOD/MOT) → Physical (MPD/MPT)
    
    Approach: Sprint 0 skeletal MCD, enriched sprint-by-sprint. Bottom-up from stories. Cross-validation mandatory. Test-driven at all levels.
