First-time users can now run a complete Java example from the README using the published 0.2.3 core artifact and Langfuse project keys. It sends fixed synthetic content, verifies three observations and their parent links through Observations API v2, and prints a trace URL. No model API key or local library install is required.

The README includes an actual Langfuse screenshot with its matching read-back JSON and provenance. A bilingual installation-feedback issue form and ready-to-review community introduction drafts provide a public feedback path. No external outreach has been posted and no external adoption is claimed.

Validation:

• Cold-cache Maven Central build and five verifier tests passed locally.
• Java 11/17/21 consumer checks, existing library/starter regressions, and quality/security CI passed: https://github.com/ChoMinGi/langfuse-otel-java/actions/runs/39137469929
• Fresh-cache public-artifact ingestion, exact parent/content checks, and browser capture passed against digest-pinned Langfuse 4.41.0: https://github.com/ChoMinGi/langfuse-otel-java/actions/runs/39137124953
• CI runs the public quick start on every PR; browser capture remains opt-in for documentation regeneration.

Library behavior and release version are unchanged. The example POM intentionally tracks the published release separately from the reactor development version. Local Docker was out of space; live verification used disposable GitHub-hosted infrastructure, and existing Docker data was not removed.
