Aug 1, 2025August 2025 monthly summary for CitizenLabDotCo/citizenlab. Focused on expanding external integration capabilities, stabilizing core data flows, and enabling historical date support. Key outcomes delivered across public API enhancements, transcription modernization, file handling, and data integrity; underpinned by solid testing and code quality improvements. Key features delivered: - Public API: File management and retrieval (CRUD, filtering, and fetch-by-id endpoints) enabling external integrations and automation workflows. - Transcription system modernization and exposure: stores raw AssemblyAI responses, makes region configurable, introduces a transcription processing feature flag, and enhances FE transcript chapters for better navigation. - File upload and storage improvements: refined upload workflow, improved project association, updated filtering and UI robustness, and extended expiry for signed images to improve reliability. - Date setup and range enhancements: allow phase starts in 1900 and introduce a startMonth prop for historical date ranges. Major bugs fixed: - Data integrity and maintenance: fixed vote_term propagation, preserved report owners, lint/test hygiene improvements, and cleanup of migration-related data relationships to ensure stable deletions. - File preview reliability with remote storage: fix for generating previews when using remote file storage and Gotenberg client compatibility. Overall impact and accomplishments: - Strengthened external API reliability for file operations, enabling smoother partner integrations and automation. - Improved transcription reliability and visibility, with configurable regions and a clear exposure path for raw responses and FE chapters. - Enhanced data integrity and maintainability, reducing technical debt and improving test stability. - Expanded historical analysis capabilities through date-range enhancements, enabling accurate reporting on long-running phases. Technologies/skills demonstrated: - API design and backend feature flags; region configurability; data migrations and integrity fixes; linting and test hygiene; remote storage integration; front-end transcript support; and UI robustness across file handling and upload workflows.
