How do resident trust funds work at a CCRC?

The same way they do elsewhere, but the balances are larger. Facilities routinely hold personal funds on behalf of residents, and for facilities participating in Medicare and Medicaid the management, accounting and assurance of those funds is governed by federal requirements.

The coverage trap is that a standard crime policy insures loss of the organization own money and property. Resident personal funds are held in a fiduciary capacity, and some forms do not reach them without a specific extension. Confirm the extension is actually endorsed rather than described in a proposal, and confirm the limit is sized against the aggregate balance the account actually carries rather than a figure chosen years ago.

Then reconcile the account regularly, independently of whoever has custody. That reconciliation is what a surveyor asks for and what makes an insurance claim provable, since a facility that cannot show what the balance should have been struggles to establish the amount of its loss.
