Reserve
Credits the venue owner holds, and the credits already allocated.
Owner reserves
Reserve is the credit balance the venue owner holds. Supply is every credit minted for that venue. Reserves are the part still with the owner. The console shows both, next to holders.
Mint
Mint adds credits to owner reserves. The amount to pay follows the rate on the Venue License, in USDC, plus a 10 bps mint fee posted to Opfico. The first mint locks that rate.
Allocated
Allocated is supply minus reserves. That is the credit already out with makers. A book cap, when set, is measured against allocated credits.
