Hi! I'm grabbing this P0 testing ticket right now. Assuming Issue #1 is ready to test against, I will write the comprehensive Soroban unit tests for reveal_prediction. I'll cover the happy path (valid reveal matching the commitment hash), and strictly test the edge cases: invalid salt rejections, double-reveal state blocks, and time-based rejections using ledger time manipulation. Can I get assigned?
