What collateral means before anyone borrows
Lending week starts with the asset posted first, then the ratio a Solana program already published.
In a branch loan, a person talks to a clerk, offers security, and waits for a decision. In a Solana lending program the decision is a ratio that was written before the reader arrived. Collateral goes in first. The amount that can be borrowed is a share of that collateral's reported value, not a courtesy extended at the table.
The Foundations Circle uses one numeric sketch. Suppose the program lends up to 70 for every 100 of collateral value it recognizes. A reader who posts collateral valued at 100 may borrow 70 of the asset the pool offers. If the recognized value of the collateral falls so the borrowed amount is too large for the ratio, the program can liquidate according to its published rule. Nobody at Cortex Compass phones the borrower. The rule was already on the page.
Two questions belong in the margin. Which price does the program read, and where is that source named? What happens to any remainder after liquidation? Public documents answer those questions in different places, and week 4 is spent finding the sentences rather than guessing the outcome.
Readers sometimes want the hour to end with a yes or no on a particular pool. The hour ends with the ratio copied into the notebook and the date of the document written beside it. Personal choices stay with the reader and any advisor they choose to consult.
The full sequence, including this Tuesday, is the Foundations Circle. The lending binder is also on the shelf for a reading room pass.
