# Commit Message for SharedArrayBuffer Platform Exclusion

Browse Source 
fix: eliminate SharedArrayBuffer checks on non-web platforms

* Add platform guard in AbsurdSqlDatabaseService to only initialize on web
* Change singleton pattern from eager to lazy instantiation
* Update worker import to use lazy singleton pattern
* Prevents absurd-sql initialization on Electron/Capacitor platforms
* Reduces console noise and memory footprint on desktop/mobile
* Maintains full web platform functionality and performance

Resolves SharedArrayBuffer-related console output on Electron platform
while preserving all web features and maintaining clean architecture.
