May 2026 monthly highlights for OpenFn Lightning and docs centered on strengthening sandbox governance, improving data visibility, and boosting UI resilience, while delivering storage and sorting enhancements that improve user productivity and business value. Key outcomes include hardened sandbox lifecycle, scalable storage presentation, safer and clearer multi-repo navigation, and stronger observability through logging and CI stability. Highlights by pillar: - Sandbox lifecycle and access controls: implemented soft-delete with a grace period to avoid data loss, surface for cancellation of deletion, and robust visibility rules to ensure operators only see sandboxes they have project membership for. Added mechanisms to surface and manage scheduled deletions within the parent sandbox listing and improved revert/restore flows. - Nesting and usage governance: introduced usage_caps_input for project settings and a nesting cap for sandboxes to prevent runaway project trees. Provisioning now derives sandbox users from the parent, enforcing per-sandbox governance and reducing permission drift. - Storage display and collection sorting: autoscaled storage values (B, KB, MB, GB, TB) with sortable storage columns across collections, improving readability and decision-making for capacity planning. - Workflow and versioning UI fixes: corrected sorting at UTC month boundaries, ensured chronological ordering, and aligned the version dropdown behavior with semantic versioning, reducing confusion for product teams and improving user confidence. - UI crash handling and observability: added resilience for unrecognized worker kill error types (StateTooLargeError), added a guarded catch-all, and improved logging and Sentry reporting for visibility into failures. - Project settings and navigation: precomputed and stabilized breadcrumb labeling for the project picker, trimming UI flicker and improving render purity and performance. - Documentation: refreshed Sandbox docs to fix inaccuracies, added sections on roles, limits, restoration, and CLI guidance, improving user understanding and governance oversight. - CI and dependencies: removed outdated CI jobs and updated the Tesla library to resolve mid-stream transport crashes, improving overall build stability. Technologies/skills demonstrated: - Elixir/Phoenix LiveView, Ecto, recursive CTEs for efficient visibility and tree-walking. - Robust UI/UX redesigns for modals and dashboards, with attention to accessibility and performance. - Observability: Sentry integration, structured logging, and metrics to monitor sandbox lifecycle events. - Performance and reliability: reduced DB round-trips via refactors, added regression tests, and stabilized CI pipelines. Business value and impact: - Safer sandbox lifecycle reduces risk of accidental data loss and improves compliance with grace-period requirements. - Clear visibility rules and per-sandbox governance reduce misconfigurations and admin overhead. - Storage and sorting improvements enhance capacity planning and decision-making for larger organizations. - Improved reliability and observability translate to faster issue diagnosis and lower mean time to recovery.
