- Ensure empty identities are correctly handled in policy management checks
- Implement strict table name validation (prevention of path traversal and character enforcement)
- Add nil checks for entry.Entry in all listing loops to prevent panics
- Propagate backend errors instead of swallowing them or assuming 404
- Correctly map filer_pb.ErrNotFound to appropriate S3 error codes
- Standardize existence checks across bucket, namespace, and table handlers
- Prohibit path traversal (".", "..") and "/" in namespaces

- Clean up unused imports in s3api_tables.go
- Update generateTableARN to match AWS S3 Tables specification
- Move defer r.Body.Close() to follow standard Go patterns
- Remove unused generateNamespaceARN helper
- Fix InclusiveStartFrom logic to ensure exclusive start on continued pages
- Prevent duplicates in bucket, namespace, and table listings
- Fail fast on listing errors during bucket and namespace deletion
- Stop swallowing errors in handleListTables and return proper HTTP error responses
- Add multi-segment namespace support to ARN parsing

- Return 403 Forbidden for unauthorized operations
- Only bucket owner can perform operations (extensible for future policies)
- Add AuthError type for authorization failures
- Specifically check for 'not found' errors instead of catching all errors
- Return empty list only when directory doesn't exist
- Propagate other errors (network, permission) with context
- Prevents masking real errors
- Reduce handler.go from 370 to 195 lines (47% reduction)
- Remove duplicate ARN parsing and path helper functions
- Remove filer operation methods moved to filer_ops.go
- Remove metadata structure definitions moved to utils.go
- Keep handler focused on request routing and response formatting
- Maintains all functionality with improved code organization
- Create bucket_create.go for CreateTableBucket operation
