The bid of 3C is 100% very limited to a minimum hand
with perhaps a little extra in distribution.

GIB says it is 12-18

With a stronger hand I would either cuebid or redouble.

It does say 12-18 total points allowing for as little as 11 HCP. Its real problem is not understanding the double of 4S as simple penalty- pass is your bid you piece of junk.

You said " The bid of 3C is 100% very limited to a minimum hand with perhaps a little extra in distribution."
I think this is only 100% your thinking instead of Gib, even Gib CC has some issues.
After East double, would you have ever thought of passing?
3♣ says "5+♣...", would you really have five card plus ♣"?
It should know that Gibs have no ability to handle with dishonest biddings.
Now please see Gib playing.

Second :

Would you tell us your hand traveller link?
If you can, I often can find a series of issues instead of only one.

I am not defending my bidding.

However, I am allowed to take a position as south.

North already took their position by making the underbid of 2C.

According to Gibs evaluation method, after West 1♦, if North Gib want to show its limited raise and cuebid 2♦, this needs 11+TPs. However North Gib only has 10 TPs, only bid 2♣, don't underbid in fact.
