What worked

Cross-platform PRD with separate platform-specific AGENTS.md files for iOS and Android. Step 02 split into 02a/02b.

What broke, and how it was fixed

First iOS submission rejected by App Review for 'minimal functionality'. Step 06 fix article 'app-review-rejected-vague' is the postmortem.

Workflow steps used

Step 04 (Context) was critical — two AGENTS.md files (one per platform) prevented the AI from mixing SwiftUI and Compose patterns.
