 That's the old framing. Here's the better one:
 
-**SpeckDL is the narrow waist that both humans and AI can work in.**
+**SpeckDL is the shared space that both humans and AI can work in.**
 
 - **Human-judgeable** — SpeckDL is declarative enough that a person can inspect a spec and say "yes, this captures my intent." The compiled Wasm is opaque; the spec is not. That's the audit trail. Intent is encoded in the spec *because* it is verifiable by a person.
 - **AI-writable** — SpeckDL's constrained grammar and declarative semantics make it tractable for LLMs to produce and reason about. Agents can draft, iterate, and refactor specs at machine speed — in the same language the human reviews.
