When to use

• When adding or changing a flow with push, modal, sheet, tab, or nested navigation.
• When supporting deep links, push notifications, auth gates, or restore/resume behavior.
• When back, up, close, dismiss, or exit behavior could be ambiguous.

Core analysis model

• Classify the flow as top-level, nested, modal, transient sheet, or external handoff.
• Define entry points and required context for each entry.
• Choose push vs modal vs sheet based on task ownership and exit expectations.
• Specify back, up, close, dismiss, cancel, and completion behavior.
• Handle deep link and notification entry without corrupting the stack.
• Account for restore/resume, auth/session expiry, and missing resources.
