Sep 1, 2025September 2025 monthly summary for Hivemapper/odc-api focusing on delivering reliable landmark data and improving distance-tracking accuracy. Key features included Landmark Confidence Metrics and Metadata Enrichment, extending the MergedLandmark type and packaging.ts to expose confidence attributes. Bug fix implemented intra-session distance gap calculation to ensure gaps are computed only within the same session, removing cross-session noise. Result: higher data quality, more trustworthy analytics, and improved motion-model reliability, enabling better mapping and reporting.

Apr 1, 2025April 2025 monthly summary for Hivemapper/odc-api. Focused on reliability and maintainability of instrumentation data access. Delivered the Instrumentation Data Access Reliability and Query Refactor feature. Implemented a pre-read file existence check for process metrics to prevent stream errors; when the metrics file is missing, the system now logs an error and returns an empty data set to avoid cascading failures. Refactored SQL queries used to select and update instrumentation data to improve clarity and maintainability. These changes reduce runtime errors, improve data quality, and simplify future enhancements.
