We should explain in more detail what we mean here – sum of pre_upgrade and post_upgrade?

See above, "upgrade message" is not a term we use elsewhere.

| ### Canister limit {#system-api-canister-limit} | |||
|
|
|||
| The canister can query one of the "canister limits", which denotes a resource limit of the canister imposed by the current configuration of the IC and/or canister. This allows runtime logic, such garbage collector or persistence mechanism, to adapt to the system limits without recompilation and redeployment. | |||

Do we return the limit (meaning: the constant) or the remaining budget in the current execution?

Should we add a limit for the remaining memory (heap or stable) pages that could still be allocated by the canister?

| - 0 : The [soft Wasm heap memory limit](https://internetcomputer.org/docs/current/developer-docs/smart-contracts/maintain/settings#wasm-memory-limit), or the IC-defined [hard Wasm memory limit](https://internetcomputer.org/docs/current/developer-docs/smart-contracts/maintain/resource-limits#resource-constraints-and-limits), whatever is smaller. The limit is specific to the canister, depending on the canister configuration (for the soft limit) and on whether it uses 32-bit or 64-bit Wasm memory. |

Should this also consider the subnet available memory?
