These surfaces are not all mutually exclusive. Historical DYEC and Dayhoff/TapDB values use active billing tags; Terrarium and Aquarium use recent resource-level data and live inventory because historical app tags are not active.
RDS/Aurora service total is $5,246.71. The apparent instance-class compute subset is $4,902.90.

Limits And Reproducibility
Cost Explorer active tag keys for this window were limited to ParallelCluster/project tags. `Name`, CloudFormation stack-name, ECS service, and RDS identifier were not active historical cost allocation tags. Therefore DYEC and Dayhoff/TapDB are separated with historical tag evidence where tags exist, while Terrarium and Aquarium are separated only in live inventory and recent resource-level Cost Explorer data. Unclassified or blank-tag spend remains unallocated rather than inferred.
