The tool's improvements were adopted upstream in OpenTelemetry PR #8684, cut Micrometer runtime by 43% (14.904 to 8.482 µs/op) and allocation by 57% (18,616 to 8,000 B/op), and fixed a Maven Deploy race reproduced 5/5 times in baseline versus 15/15 correct in candidate.

No proof, no PR.\n\n## One small improvement. Repository-native proof.\n\nJAIPilot improves only changed production paths, publishes against the feature branch, and never auto-merges. Failed identity, tests, build, or evidence means no PR.\n\n[Full audited results: all 60 live drafts, 33 no-changes, costs, and limitations](https://github.com/JAIPilot/jaipilot/blob/main/CLOUD_RESULTS.md).\n\n### OpenTelemetry: adopted upstream\n\nRemoved redundant timeout scheduling from synchronous export: **1 schedule/cancel pair → 0**. The contributor [adopted it into upstream PR #8684](https://github.com/open-telemetry/opentelemetry-java/pull/8684/commits/acca5b7d5553b59a228e3322183e131cae4f53af). **32 focused tests; 161 build tasks passed.** [Draft](https://github.com/skrcode/opentelemetry-java/pull/2).\n\n### Micrometer: 43% faster, 57% less allocation\n\nRemoved per-call HashSet work: **14.904 → 8.482 µs/op** and **18,616 → 8,000 B/op**. **75 focused tests and both affected module builds passed.** Same-host JMH over 200 rows. [Draft](https://github.com/skrcode/micrometer/pull/2).\n\n### Maven Deploy: atomic cache initialization\n\nAtomic initialization removed duplicate full-reactor scans. A 16-thread regression reproduced the baseline race **5/5**; the candidate produced exactly one scan **15/15**. **29 tests, Checkstyle, RAT, and the clean offline build passed.** [Draft](https://github.com/skrcode/maven-deploy-plugin/pull/2).\n\n### JavaParser: terminate cyclic traversal\n\nShared-node expansions fell **2 → 1**; a cycle fixture went **timeout → ~20 ms**. The full reactor passed **2,094 tests**. [Draft](https://github.com/skrcode/javaparser/pull/3).\n\n### Honest outcomes\n\nAudited public 95-run campaign: **60 live drafts, 33 safe no-changes, 1 rejected, 1 withdrawn after independent audit, and 0 auto-merges.**\n\n### Free for public open source\n\n10 eligible evaluations per GitHub account or organization.
