Hlido verdict

Hlido tested both. Humanloop scored 40 (FADING); LangSmith scored 53 (FADING). LangSmith leads by 13 points. Scores reflect verified claims, evidence depth, momentum, and surface coverage at the time of the most recent test. Re-tested periodically — drift over time is itself a signal.
