On the issue of the verification of this run's unseeded status, if you would like to see the video of the entire session with no editing or trimming, which includes the lobby unseeded screen verification, click here, there will be timestamps in its description: • Speedrun raw session footage
Before submitting this run, I asked to some of the members of the Monolith community who are involved in racing and speedrunning the game, and asked them if a run showing the seed of the previous run (before restarting), and then the current run having a different seed number, would be enough of a valid certification that it is, in fact, an unseeded run. The overall consensus was yes, although this would not be the ideal method of verification. That is why in the description I included footage that shows that happening, albeit with 30 minutes of failed attempts in between.
Lastly, this run's position in the speedrun.com leaderboard, although submitted by me, was ultimately verified and approved by someone else (Lilac), to ensure that there was satisfactory proof of its unseeded status.
