the manifest
Everything in the face, and every rule that governs getting it out. None of it can be changed — there is no function for it.

the draw
A cut is a random pick from exactly the blocks still in the face — a shrinking Fisher–Yates draw, done in the contract. Nothing is ever re-rolled or put back, so the counters on the front page are the odds: with 5 gold left in 812 blocks, the next cut is 5 in 812.
commit, then open
You pay when you cut. Your block is decided by the hash of a chain block that did not exist yet when you cut, and comes out when anybody opens it — usually the next person to cut, or you. Cuts open strictly in the order they were made, so nobody can choose which cut gets which block. A cut nobody opens within about 250 chain blocks (roughly 50 minutes) crumbles to dust: no block, no refund.
the price
The first cut burns 2,000 $QUARRY. Every cut made adds 5 to the next. The last cut costs 22,475. Early cuts are cheap; late cuts have the best odds anyone will ever get.
the gold seam
90% of every cut is burned. 10% runs into the seam and is split seven ways — one seventh per gold, whether it is still in the face or not. Cut a gold and you are paid everything its seventh has gathered, in the same transaction. Hold a gold and you keep earning from every cut after. Sell one and you are paid what it gathered first.
the yard
Every block that comes out is an ERC-721 drawn entirely on chain: its stone, strata, veins and chips are a hash of its number, and its tag says which cut it was. Sell it inside the contract — 95% to the seller, 5% burned — or on any marketplace.
what the contract cannot do
Hold ETH (nothing is payable). Mint a block outside the draw. Put a block back. Change the manifest or the prices. Take a royalty. Pause. Upgrade. The owner key names the token once and is inert forever after.
the plain risk
This is a draw. Most cuts are rubble and slate, and the burn is gone either way. The randomness comes from the chain's own block hashes, which the network's sequencer produces. Unaudited. Cut what you can lose.
