### `size_538_loan`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Sizes a USDA Section 538 loan the way the site's loan sizer does: the 90% (for-profit) or 97% (nonprofit or public) cap on the lower of cost or value against the DSCR cap (1.15x default), with NOI, debt service, loan-to-cost and the 2026 guarantee fees. Arithmetic on your inputs, not a quote.
