Impact Analysis for Code Changes

Help me identify what to regression test based on these code changes.

CHANGES MADE:
[Describe the code changes or paste the PR summary / diff summary]

FILES CHANGED:
[List the files or modules modified]

APP ARCHITECTURE:
- [Describe relevant architecture — MVVM, Clean Architecture, etc.]
- [Describe navigation structure]
- [Describe shared components or utilities affected]

Analyze the impact:
1. Screens directly affected by the changes
2. Screens indirectly affected (shared components, dependencies)
3. Features that use the modified code paths
4. Data flows that pass through changed modules
5. Platform-specific concerns (does this change affect iOS, Android, or both?)

Produce:
- Targeted regression test list (only what's needed, not full suite)
- Risk areas that need manual exploratory testing
- Areas safe to skip (confidently unaffected)
