### Changed

- **Positioning shift**: From "Privacy-first belief attestation" to "Trust Layer for Base"

### Fixed

- **TypeScript compilation errors** - Excluded SDK from root tsconfig.json to prevent conflicts
- **Webpack build failure** - Fixed unescaped apostrophe in BuildWithVaultfire.tsx:30
- **CI test failures** - Root tsconfig.json was trying to compile SDK files with different dependencies
