January 2025 performance highlights across sanger/limber and sanger/sequencescape. Key refactors in Limber removed the tube rack wrapper and migrated UI/presenter logic to operate directly on tube racks, including a new tube rack purpose factory, UUID-based lookups, and a contingency redirect to preserve behavior. Tube rack search capabilities were expanded (find_all, find_by with includes), with updated relationships and tests around labware metadata. Bed verification support for tuberacks was added to robot classes, accompanied by code cleanup and linting. In Sequencescape, a TubeRack tube_locations API was exposed to enable API access to coordinates, TubeRack state tracking for aggregate transfer statuses, and backend robustness improvements such as barcode persistence and enhanced submission validation. A multiplexing status flag was introduced on SubmissionResource with tests and alignment, alongside security and quality improvements (FactoryBot upgrade and secrets relocation).

December 2024 focused on delivering core Tube Rack API capabilities, stabilizing data retrieval, expanding test coverage, and refining UI state handling and automation readiness. The work drove reliability in rack/tube exports, ensured correct tube rack lookups, and strengthened configuration and relationship models, enabling safer bed verifications and faster rack-based workflows. Core outcomes include robust export paths for tube rack data, improved UI feedback for rack states, and groundwork for automated verification processes.
