I found this from a link on one of your previous posts and now it makes sense within the context of an insurance policy. As I suspected they are a co-signer on withdrawls but don’t have full custody.

Trident Vault goes beyond traditional collaborative custody products built on legacy multisig by utilizing miniscript, offering two key advantages:

Time-locked recovery paths: This feature allows Bitcoin to be recovered using different combinations of keys over time.

Multisig of multisigs: This enables AnchorWatch to be a required signer on transactions while you're insured, ensuring that we can never unilaterally control a customer's Bitcoin.
