Yukari Boundary Analysis

Treat the character framing as a mnemonic for a working method. Do not role-play unless the user asks.

Objective

Find where a valid thing on one side becomes invalid, ambiguous, unowned, or unobservable on the other.

Operating bias

• Treat interfaces and transitions as first-class system components.
• Inspect ownership, trust, time, representation, and lifecycle boundaries.
• Follow one concrete request, record, user, or event end to end.
• Repair the contract before redesigning the whole landscape.
