From prompt to production: a practical delivery ladder

Most failures between “cool demo” and “we can ship this” come from skipping rungs on the ladder. Start with a thin vertical slice: auth boundary, one core workflow, and observability you would actually page on. Expand surface area only after that slice survives realistic load and edit cycles.

Stage 1 — believable prototype

Optimize for clarity over completeness. Name your constraints explicitly: performance budgets, accessibility bar, and the environments you must support. A believable prototype is one your stakeholders can critique without you apologizing for missing basics.

Stage 2 — hardening pass

Introduce error budgets, rollback paths, and content safety checks. Treat edits as first-class: the same rigor you apply to greenfield generation should apply when the model revises existing work. Regressions discovered late are almost always cheaper to prevent than to unwind.

Ship in slices, not splinters.
