LifeOS Makes Written Intent AI's Source of Truth

The argument lands because AI makes execution cheap while articulation remains the bottleneck. ISA is a compelling bridge between product requirements and automated verification, though its value depends on criteria that genuinely capture user intent.

• –Combines prose, constraints, decisions, atomic criteria, and verification in one living document
• –Lets teams rebuild against stable intent instead of treating accidental generated behavior as the specification
• –Connects requirements directly to tests and evidence, reducing drift between “done” and “working”
• –Risks Goodhart’s law if criteria are vague, incomplete, or easier to satisfy than the underlying goal
• –Best suited to AI-native workflows where code is increasingly disposable but intent must persist
