July 2025 monthly summary for eclipse-apoapsis/ort-server. This period focused on strengthening reliability and developer efficiency by capturing detailed failure context and simplifying the user interface. Key changes include: (1) Job Failure Error Message Capture – added an error_message column to job-related tables and corresponding data models (Advisor, Analyzer, Evaluator, Notifier, Reporter, Scanner) to store detailed failure information for failed jobs, enabling faster debugging and root-cause analysis. (2) UI Cleanup – removed outdated .netrc guidance from Infrastructure Services UI to reduce user confusion and streamline credentials troubleshooting. These changes were implemented in commits 499a0bf39527bfc0905c06c3298100c981cc6343 and 0917d3e64057b60dd6cfe390b255c42f0b7749ee respectively. Overall impact includes improved triage speed, better actionable analytics for failures, and a cleaner user experience.
