| mark | max(oracle, pool TWAP), clamped at a band over the oracle. Every debt, health factor and liquidation in StockLend uses it. |
| band | How far over the oracle the mark may follow the pool. Frozen into each loan at the open, so a regime change cannot reach an existing one. |
| regime | Open or closed, from the on-chain trading calendar — or from a feed older than six hours, which is the fail-closed backstop, not the primary test. |
| buyIn | After maturity, anyone spends the borrower's collateral in the pool to buy the shares back, capped at the settlement price plus a slippage allowance that grows hourly. |
| writeOff | The collateral buys back neither the debt nor a single share. The shortfall is shared across lenders by share, and the leftover USDG goes to them. |
| weekend premium | The pool price over the frozen oracle during a closed session. What a borrower pays to sell into. |
| payout | Stock sent to $HEDGE holders by balance each round: the holders' share of the tax plus what the treasury's stock earned. |
| treasury inventory | Stock the treasury holds and works. Never sold, never shorted; lent on weekends, written against on weekdays. |
| covered call | Selling, for a premium, the right to buy the treasury's stock at a strike before expiry, with the stock locked as collateral. |
| any stock | The treasury can hold any stock token that has a lending or options market here; NVDA is only the first. |
| USDG | The stablecoin every stock pool on Robinhood Chain is quoted against, and what collateral and fees are denominated in. |
| uiMultiplier | The per-token factor that carries corporate actions. Chainlink's RHxxx / USD answer already includes it — see the three prices. |
