What is Pass-1 Build?
The uninterruptible first generation surface: styles, layout, page, components, then validation. Letting pass one finish prevents half-built states that later edits have to repair.

Guided Preflight
The multi-step setup wizard BYOB runs before generating code: refining the prompt, identifying features, proposing UX direction, and choosing data options. Planning first is what separates coherent apps from random screens.
Lucky Build (Autopilot)
The one-shot fast path that skips guided setup and generates directly from the prompt. Best for experiments and landing pages; guided preflight wins for anything with data or auth.
Smoke Check (npm run check / build)
The cheapest reliable gate: typecheck plus production build. Run it after every structural change — it catches breakage code review would take ten times longer to find.
Act Mode
The gear where BYOB edits files, connects services, runs checks, and moves the project forward. Chat Mode reasons and plans without touching files; Act Mode executes once decided.
Intent Classifier
The router that sorts requests into bugfix, UI-only, full-stack, or backend-only work before acting. Correct classification keeps small asks cheap and stops UI tweaks from triggering migrations.
Agent Blueprint
The create-time record of a project’s seed, axes, and build plan. Blueprints make generation reproducible: the same brief plus the same plan rebuilds the same shape.
