Skill: TraceMem Complete Workflow Patterns

⚠️ CRITICAL RULE: Decision Envelope is MANDATORY

The Decision Envelope is NOT optional.

ALL TraceMem operations MUST happen within a decision envelope:

┌─────────────────────────────────────┐
│   DECISION ENVELOPE (decision_id)   │
│  ┌───────────────────────────────┐  │
│  │  ✓ decision_read              │  │
│  │  ✓ decision_write (CRUD)      │  │
│  │  ✓ decision_evaluate          │  │
│  │  ✓ decision_request_approval  │  │
│  └───────────────────────────────┘  │
└─────────────────────────────────────┘
