I should admit that Gib's 3♦ is a best contract.
Here don't care about the result.
Gib bid new minor - 3♦ which is alerted as " 5+♠,4+♦ ", is it not forcing?

I'm not a GIB expert but this is my impression:
GIB doesn't really have a concept of a "forcing" bid - it sometimes explains things as forcing but that is just an annotation, and it doesn't have the rule that all unlimited bids are forcing.
This particular auction is not defined in its rule base so it just defaults to natural bidding which here apparently means that 3♦ shows 5+spades and 4+diamonds, any strength. And then East makes some simulations and pass turns out to be the average winner.
Of course it is unplayable that 3♦ is completely undefined w.r.t. strength.

The world would be such a happy place, if only everyone played Acol :) --- TramTicket

It would be interesting to know what would be meant by a redouble by West, then perhaps a 3D followup
Psych (pron. saik): A gross and deliberate misstatement of honour strength and/or suit length. Expressly permitted under Law 73E but forbidden contrary to that law by Acol club tourneys.
Psyche (pron. sahy-kee): The human soul, spirit or mind (derived, personification thereof, beloved of Eros, Greek myth).
Masterminding (pron. m
s
t
r-m
nd
ing) tr. v. - Any bid made by bridge player with which partner disagrees.
"Gentlemen, when the barrage lifts." 9th battalion, King's own Yorkshire light infantry,
2000 years earlier: "morituri te salutant"
"I will be with you, whatever". Blair to Bush, precursor to invasion of Iraq

Currently for GIB in such auction:
Pass by partner shows exactly 2 cards in the transferred major.
XX by responder turns into GF and shows 10+ ( so XX and 3♦ later shows same length, just 10+TP and GF )
All other unbid suits are 9 or less TP and natural.
While partner has exactly 2 cards in primary major, it's almost certain he has 3+ in side unbid suit.
With something like 5-7HCP and 5-5 or 5M6m hand you will unlikely prefer 5-2 while you have 5-3 or 5-4.
Opener could XX to show nofit+max or pass with nofit+min.
So based on partner with min values new suit just comes for pass/correct.
It will be reviewed for something more flexible, but meantime it's as GIB plays it.

In the meantime can the descriptions be corrected, so 3♦ (for example) shows the applicable point range?
