unclear purpose of `IPolicy.ClaimState.Declined`

[rapidddenis]

In https://github.com/etherisc/gif-contracts/blob/b58fd27a34452e062d10b175f3bdd7ee16b9d1a7/contracts/modules/PolicyController.sol

ClaimState.Declined have no usage outside of PolicyController where it influences nothing.

[matthiaszimmermann]

the semantics of declining a claim is a (non-parametric) product where the policy holder would be allowed to create a claim. in such a situation the insurer needs a way to flag invalid claims.

this is done via the ClaimState.Declined state and can be set via base contract Product._declineClaim in the gif-interface repository.

APPLIED-> CONFIRMED->CLOSED / APPLIED->DECLINED. No close is needed for declined claim? Two "end" states? If claim is closed after declining then anyone who is trying to see the whole picture will have to dig into the logs?

[matthiaszimmermann]

yes there are two end states for claims. for applications there are even 3 end states.

to see the whole picture for a specific policy the InstanceSerive functions claims and getClaim may be used. corresponding functions are provided for payouts.

[rapidddenis]

Current implementation requires declined claim to be closed, otherwise policy will not close. So declined is not the end state.
