Capacity
The only way to hold a larger share of what the engine releases is to destroy FORGE that exists today. It does not come back. What you get for it is a share of a stream whose size the market sets, not you.
Burned, not locked. Capacity is permanent until you release it, and the FORGE never comes back. Claiming costs 10% of the capacity that earned it.
Forging
You approve, then call forgeCapacity. The contract burns the FORGE out of your wallet and credits you the same number as capacity. There is no deposit sitting anywhere to be withdrawn later.
Accruing
Every time the engine settles, the epoch's release is split across all capacity in proportion. A rate that the market has cut applies to you exactly as it applies to everyone else.
Leaving
Claiming pays what has accrued and burns 10% of your capacity. Releasing capacity walks away without claiming, and exists so nobody is trapped in the accounting.
