@robustfengbin you need to post to the Forum for community feedback. Post the link here once that's done. Also, startup + milestones must equal the total budget amount. Either remove the startup funding or reduce milestones by $3,000.

@ruzcash Thanks for the feedback! I've updated Milestone 3 in the issue to reflect the $6,000 fixed / $3,000 conditional split for OSS-Fuzz acceptance, consistent with the forum discussion. The total budget remains unchanged at $30,000.
