Coverage check

A pre-flight checklist for your design. Coverage maps your screens into a flow tree and flags pieces a reviewer would notice are missing — like a Login screen with no recovery flow, or a screen nothing links to.

What it does

Maps the flow. Reads your screens and prototype interactions, builds a top-down tree. Click any node to jump to that screen.
Flags gaps. Catches broken navigation, dead-end screens, orphans, and clearly-implied missing screens. Conservative by design — it stays quiet when in doubt.
Doesn't change your design. In Phase 1 it only reports. Auto-fix arrives in Phase 2.

When it runs

Once when you open the Coverage tab in the right panel.
On demand via the Re-check button.
When you click Export with unresolved gaps — you'll see a non-blocking warning. You can always export anyway.

What it won't do

It won't second-guess creative decisions or flag stylistic choices.
It won't surface more than the top six issues at a time.
It won't run on every keystroke. Results are cached so re-opens don't re-bill.

Severity levels

Critical — broken navigation, missing required flows (auth recovery, payment confirmation).
Warning — orphan screens, dead-ends, screens nav explicitly references but you haven't built.
Info — minor mismatches, optional nudges.

Coverage costs 2 coins per analysis and is cached per design state, so re-opening a project doesn't re-bill.
