_This issue was generated automatically by Claude Code (Anthropic's AI coding agent) running a scheduled CI-triage routine on behalf of @FrankChen021. Analysis and suggested fixes are AI-produced; please verify before acting on them._ **Status:** Resolved by #20506 **Subject:** `ProtobufEventSerializer` test compile break (embedded-tests, every Maven job of Static Checks CI, CodeQL and Unit & Integration tests CI) **Failures:** 20 · **First seen:** 2026-10-07 · **Last seen:** 2026-10-07 ### Root cause Semantic merge conflict between two PRs that were each green on their own. #20485 (a758f52dfc) renamed `MoreResources.ProbufData` to `MoreResources.ProtobufData`; #20495 (a38a81f1ce), branched before that, rewrote `ProtobufEventSerializer` to reference the old `ProbufData` name. After #20495 merged, `druid-embedded-tests` no longer compiled, so every job that builds test sources failed. ### Suggested fix Use `MoreResources.ProtobufData` in `ProtobufEventSerializer`; done in #20506 (merged 2026-10-07). To catch this class of break, consider requiring PR branches to be up to date with `master` before merge, or a merge queue. ### Occurrences Failed push-triggered master jobs only. The daily triage routine adds one row per new failed job. | Date | Commit | Job | Failure log | Detail | Reported in | |---|---|---|---|---|---| | 2026-10-07 | a38a81f1ce (#20495) | `Analyze (java)` |
