# Research: PWA SW Updates & Offline Write Safety

## Hypothesis
With cache versioning and cautious update prompts, we can avoid data loss during app updates and schema bumps while offline.

## Questions
- Best timing for SW activation without disrupting writes
- Handling schema migrations when a stale SW is cached
- Safe rollback strategy

## Method
- Simulate offline state; bump schema; observe SW activation and data integrity

## Acceptance
- No data loss or corruption across update/migration
- Clear UX for update available and post-update state

## Deliverables
- SW update policy, cache naming, migration/rollback checklist
