The active insulin (IOB) is not correctly reported #2319
Description
Activity
I believe this is as designed. The reported Active Insulin assumes no further action from Loop (in case communication is lost). Once a pump is commanded with a temporary basal rate, unless the temporary basal is interrupted, that amount will be delivered (or withheld). (Edited to change the phrase "insulin delivered" to "Active Insulin".)
I defer to @ps2 on this one. If he agrees, then I will close the two PR associated with this issue.
I appreciate the explanation, but I have to respectfully disagree. IOB stands for “Insulin On Board”, not “Insulin Planned for Delivery.” If it stays like this, it’s just misleading.
As a possible solution, could we consider splitting IOB into two values? One for insulin actually delivered, and another for planned insulin, e.g.: 1.1U → 2.2U (which is what I did for myself). That would keep things safe and transparent, while improving clarity.
Also, on the design choice — can we open this up to broader discussion? Loop is an open-source, community-driven project, and it would be great to have a more inclusive dialogue on decisions like this.

Describe the bug
The active insulin (IOB) reported by the UI is not the actual amount, but includes the planned one over the next 30 minutes (of basal insulin). This can be misleading, because:

Expected behavior
Loop should report as active insulin the insulin which is actually active "right now".
