April 2026 monthly summary: Focused on reinforcing data integrity in the IntersectMBO/cardano-db-sync ingestion path. Delivered a targeted fix to the ParamProposalEncoder to align parameter order with the ParamProposal record and its decoder, ensuring values are encoded and stored correctly. This correction prevents misalignment between min_pool_cost and coins_per_utxo_size and eliminates a class of data integrity issues in param_proposal writes. The change is supported by a single commit (ce232eddc564f0fb36b6a9c2c2717e74e491c102) with notes on resync/migration for existing rows. Overall impact includes reduced downstream risk, more reliable analytics, and simplified future maintenance.
