This should be strict enough, not sure what more strict than this would look like.
nitpick, we can have a method (called maybe issue(amount)
) on tracker struct itself for increasing the issued
with this check there itself.

It's still possible for a single account (or multiple ones) to claim excessive amounts of rewards, if a bug happens in dApp staking. But it's not indefinite.
nitpick, we can have a method (called maybe issue(amount)) on tracker struct itself for increasing the issued with this check there itself.
We could add that, but we cannot reuse it in on_timestamp
since that has to be infallible 🙂

I know this will be ensured by tests that this'll not happen, but what if it happens then even for the next blocks we might be issuing more than cap, though unlikely as payout needs to be more than emission, right?

You're right this must be ensured by tests.
The config is static enough, and calculation is quite predictable so I don't believe we'll ever be seeing a scenario when this overflows.
In a scenario when this happens, collator and treasury rewards would keep being issued.
But staker & dApp rewards would no longer be claimable. This would be a big deal, an issue would be raised and we'd have to deal with it.
At least, that was my idea when writing this 😄
