The Forge

• Epoch length, seven days, set at deployment and never written again.
• The base block of 1,000,000 PONM and the halving every 26 epochs.
• The digest a proof has to clear, and the fact it binds the chain, the contract, the epoch, the seam and the miner.
• The split: each seam's slice of the block, divided by the work proved on that seam.
• A seam's slice, fixed the moment it opens. Every slice that can take work in an epoch counts toward a 100% cap, so no epoch can mint more than its block.
• The reward token, once set. It can be set once and never redirected.

• Open a new seam with a slice that fits under the cap, up to 16 seams.
• Change a seam's difficulty.
• Close a seam, which stops new proofs on it and nothing else.
• Point the mine at $PONM once, when the token exists.
• Hand ownership to another address.
• Top the mine up. Anyone can: it is a plain token transfer to the mine.

The owner cannot change a seam's slice, take a claim, change a past epoch, mint outside the schedule, or stop somebody claiming what an epoch already settled.
