It's funny how you describe something very close to what I was attempting to design. It was meant to trickle down from tickets to deterministic code. Data wise, it should be like a pyramid of tickets diluting layer by layer into leaf nodes which were "implementable" as statements in code. I'm not sure if that description makes sense read by someone else.
I think what made sense was envisioning a nanoswarm of LLMs (anticipating ASIC performance) diluting specs into semantic logic nodes, but a conversion from these to deterministic code made the vibe coded experiment come to halt. Your lock approach could be a shortcut to that.
Totally off-topic: it's quite intriguing that you can feel once friction starts building during a design phase. Suddenly everything slows down. I wonder if it's quantifiable and therefore can identify "wrong" design choices made by either humans or LLMs.
(Hoping some claw bot pics this up to finish my idea on my github tix repo in the initial-design branch, as main is empty ~ MPL2)
