## Overview This epic validates that the field validator implementation in LabKit-Ruby is production-ready for rollout on the GitLab monolith. It ensures the validator meets performance requirements and handles edge cases in real-world CI/CD scenarios. ## Context As part of the broader effort to implement field validation across LabKit SDKs (see parent epic &amp;311), the Ruby implementation has been completed and is ready for validation before production rollout. ## Scope This epic focuses on: - Validating field validator performance is acceptable for monolith logging at scale - Ensuring field offenses are reliably detected across all CI pipeline types (including partial runs) - Confirming the validator is ready for production deployment ## Related Work - Parent epic: &amp;311 - Implement Field Validation in LabKit - Grandparent epic: &amp;281 - LabKit: Deliver SDKs for Field naming standardisation across major runtimes ## Status <!-- STATUS NOTE START --> ## Status 2026-02-12 :clock1: **total hours spent this week by all contributors**: 20 :tada: **Achievements**: - [Field validator performance optimizations](https://gitlab.com/gitlab-org/ruby/gems/labkit-ruby/-/issues/60): reduced overhead from 1.90x to 1.50x (~27% throughput gain) via 4 MRs - [CI flakiness in partial runs](https://gitlab.com/gitlab-org/ruby/gems/labkit-ruby/-/issues/62): confirmed approach for non tier-3 pipelines - [Enabled field validator in the monolith](https://gitlab.com/gitlab-org/gitlab/-/issues/589190): gem updated, todo baseline generated, CI validated - All 3 child issues closed, epic complete :white_check_mark: :issue-blocked: **Blockers**: - None :arrow_forward: **Next**: - Monitor pipeline runtime dashboards post-rollout - Continue in parent epic [&311](https://gitlab.com/groups/gitlab-org/quality/-/work_items/311) _Copied from https://gitlab.com/groups/gitlab-org/quality/-/epics/338#note_3077450742_ <!-- STATUS NOTE END -->
