Strata security record

When depositing or withdrawaing from either the junior or senior vaults, the `shortfallPauser()` function is called. This function pauses deposits into both tranches in case that the share price in the JRT vault falls below a specified value. This can occur when debt obligations of the junior tranche as paid into the senior tranche in scenarios where the senior tranches promised yield could not be met. As part of a deposit, first, the accounting and debt is settled via `updateAccounting()`, followed by the actual deposit flow and then the mentioned shortfall-pause-mechanic. Notably, a triggered shortfall does not revert the transaction, but simply disables future deposits and emits an event. This ordering however means that a potential final large deposit, solidifying a shortfall, into the JRT could possibly mint shares far below the configured `jrtShortfallPausePrice`, which is intended to be the minimum price of the tranche. Such a depositor could possibly mint junior tranche tokens at a significant discount and see the value increase back to normal as future yield is generated by the protocol.

A reverting registered vault does impose significant DoS to the system. The `MetaVault._redeemRequiredBaseAssets()` function does contain try-catch logic for withdrawal-attempt, but such logic is not integrated into other functions interacting with the registered vaults. Attempts to transition the vault into the yield phase would fail, as such a vault would also cause a revert in the `_redeemAndClearMetaVaults()` function. However, the vault could also not be removed, as calls to `removeVault()` would also revert, due to the external call to the registered vault's `redeem()` function in `_removeVaultAndRedeemInner()` is also not within a try-catch block.
