Pull Request

Summary

Optimized player registration storage by introducing a compact data format. Boolean fields are stored using bit flags, registration timestamps are packed more efficiently, and the overall storage footprint per player has been reduced while preserving existing functionality.

Changes Made

• Implemented compact storage format for player registration data
• Replaced individual boolean fields with bit flags
• Packed registration timestamps into a more space-efficient representation
• Updated serialization and deserialization logic
• Added benchmarks to measure storage savings and performance

Testing

• Verified player registration data is stored and retrieved correctly
• Confirmed bit flag encoding and decoding produces expected values
• Validated timestamp packing and unpacking accuracy
• Ran benchmark comparisons to confirm reduced storage footprint
• Ensured existing registration workflows remain unaffected

Acceptance Criteria

• Reduce per-player storage footprint
• Use bit flags for boolean fields
• Pack registration timestamp efficiently
• Benchmark improvement
