Looks good to me.
I'm still not quite sure how we can ensure profiles and gas match everywhere... But I gave it another round of questioning myself about cases we might have forgotten but couldn't find anything. And I would reason that we should have everything as follows:
- We use the gas profiles instead of the old counter only for function calls, which narrows down the potential problems.
- Inside function calls, we either pay for host function calls in VM logic or we account for the WASM op counter. The first case always goes through one of
pay_action_accumulated,pay_perorpay_base, which we have now covered. The second case (WASM cost) is already computed through profiles, so there shouldn't be any changes. - There is (always) one exception:
contract_loading_feeis not a host function but is still charged from the dynamic gas. Fortunately, we charge it usingpay_perandpay_basewhich covers this concern as well. - Other places have no business changing the function call gas cost.
All in all, I think we can merge this again and should be fine this time.

feature: Limit compute usage of a chunk The commit addresses near#8265 by introducing aggregation of compute usage across all operations performed during chunk application and limiting this compute usage to 1s. This should not change the behavior of nodes in the short run because compute costs match gas costs which is validated by the `assert`, so any discrepancy should be caught on canary nodes. There are two follow-ups to this work: - near#8859 - near#8860
