Qualification Phase Evaluation

What does the statement above the Leaderboard mean, “The leaderboard scores are considered official. The top 30 teams will advance to the next stage, subject to a manual review of their submissions to ensure compliance with challenge rules.”?

Does it mean there will be no further evaluation and the LB score by the end of the qualification phase is the sole determinant for qualifying (apart from manual review of the code to ensure compliance) ?

@Yadunund , Could you please clarify this.
