You: "Create a sheet set for these 12 floor plans"
AI:  "Here are the steps you should follow manually in Revit:
      1. Go to View > Sheet Composition > New Sheet
      2. Select your title block...
      3. Repeat 12 times..."

User Goal: "Create construction documents"
    ↓
Autonomy Engine decomposes into plan:
    1. Create sheet set (SheetMethods)
    2. Place views on sheets (ViewMethods)
    3. Add annotations (AnnotationMethods)
    4. Generate schedules (ScheduleMethods)
    5. QC check (Intelligence)
    ↓
Each step gets BIM-domain alignment injection
    ↓
Corrections from past sessions prevent known mistakes
    ↓
Progress cascades to parent goal: 100%
