+## Implementation Notes
+
+### Approach taken
+- Added Bluesky to Domain::DomainType enum with BSKY abbreviation
+- Created Domain::User::BlueskyUser model following FA/E621 patterns with aux_table :bluesky
+- Created Domain::Post::BlueskyPost model with proper associations and view methods  
+- Used aux_table approach for storing domain-specific data in separate tables
+- Added domain helpers for Bluesky support in DomainModelHelper
+- Created comprehensive migrations for both aux tables
+- Fixed all Sorbet type issues with proper nil safety
+
+### Features implemented
+- **BlueskyUser model**: state management (ok/account_disabled/error), due timestamps for profile/posts scanning, relationships for created/faved posts, proper view methods for external URLs and display names
+- **BlueskyPost model**: state management (ok/removed/scan_error/file_error), AT Protocol URI support, engagement metrics (likes/reposts/replies), content arrays for hashtags/mentions/links, proper associations with users and files
+- **Database schema**: aux tables with comprehensive fields for Bluesky-specific data, proper foreign keys and indexes
+- **Domain integration**: view prefixes 'bsky', proper domain type integration, consistent param handling
+
+### Technical decisions and trade-offs  
+- Used base Domain::PostFile instead of creating BlueskyPostFile subclass for simplicity
+- Followed existing domain model patterns from FA/E621 for consistency
+- Used jsonb columns for storing arrays and raw API responses  
+- Avoided conflicting column names between main and aux tables
+- Implemented proper Sorbet type safety with flow-sensitive typing fixes
+- Used AT Protocol URI parsing for post identification
+
+### Modified or added files
+- **Models**: app/models/domain/user/bluesky_user.rb, app/models/domain/post/bluesky_post.rb
+- **Helpers**: app/helpers/domain/domain_type.rb, app/helpers/domain/domain_model_helper.rb  
+- **Migrations**: db/migrate/20250805070114_add_aux_tables_for_domain_users_bluesky_users.rb, db/migrate/20250805070115_add_aux_tables_for_domain_posts_bluesky_posts.rb
+- **Generated RBI files**: sorbet/rbi/dsl/domain/user/bluesky_user.rbi, sorbet/rbi/dsl/domain/post/bluesky_post.rbi, plus aux table RBIs
+
+The foundation is now ready for implementing Bluesky scraping functionality with proper data models and database schema.
