Worked on the helium/proto repository to enhance data observability and contract quality by extending the valid_data_transfer_session message in packet_verifier.proto. Introduced a burn_timestamp field, using Protocol Buffers, to accurately record burn transaction timestamps for data transfer sessions. This addition enables more precise logging, validation, and troubleshooting of burn events throughout the data pipeline. The work emphasized clear documentation and thorough commenting to support future evolution and onboarding. Focus remained on feature delivery, with no major bugs reported or fixed during the period. The technical approach centered on protobuf schema design and documentation best practices to improve analytics and maintainability.
