+## Implementation Notes
+
+### Approach taken
+- Added Bluesky to Domain::DomainType enum
+- Created Domain::User::BlueskyUser model following FA/E621 patterns
+- Created Domain::Post::BlueskyPost model following existing conventions
+- Used aux_table :bluesky for both models to store domain-specific data
+- Added domain helpers for Bluesky support
+- Temporarily commented out aux table field references until migrations are created
+
+### Features implemented
+- Basic Bluesky user model with state management, timestamps, and relationships
+- Basic Bluesky post model with file and creator associations
+- Proper domain type integration
+- View helper methods for external URLs, names, and status display
+- Typecheck-passing implementation
+
+### Technical decisions and trade-offs
+- Followed existing domain model patterns for consistency
+- Used base Domain::PostFile instead of creating BlueskyPostFile subclass (can add later if needed)
+- Temporarily stubbed aux table fields with TODO comments until database migrations are ready
+- Used proper Sorbet typing and method signatures throughout
+
+### Modified or added files
+- app/helpers/domain/domain_type.rb - Added Bluesky enum
+- app/helpers/domain/domain_model_helper.rb - Added Bluesky support
+- app/models/domain/user/bluesky_user.rb - New user model
+- app/models/domain/post/bluesky_post.rb - New post model
+
+### Next steps
+- Create database migrations for bluesky_users and bluesky_posts aux tables
+- Implement actual scraper logic for Bluesky AT Protocol
+- Add proper field validations once aux tables exist
+- Implement AT URI parsing and post identification logic
