House rules of the open

Sealed until the bell
Over the weekend only a hash and an escrow deposit are public. Open order books on a closed market leak intent; a sealed book cannot be front-run into the Monday gap.
One price for everyone
The clearing price is the level that crosses the most shares. Every filled order pays it, so the open is set by the whole weekend book, not the first bot awake.
Escrow, then settle
Commit, reveal, clear and settle are Anchor instructions on devnet. Deposits sit in a program vault; the heavy side fills pro rata and the rest is refunded.
