How does a crafted Ioun Wyrd work?

[Yuriyuyeimi]

Hello everyone, kinda new here. So the Ioun Wyrd creature, which can be selected as a Familiar, also has construction requirements to be crafted with the Craft Construct feat.

If you follow the crafting rules for the Ioun Wyrd and don't pick it up as a familiar does it retain it's share iouns ability and is it useful to the crafter?

And what happens if you craft it first, then pick up the familiar ability and lastly you choose it as your familiar? would you be able to modify the construct later as per the Building and modifying constructs rules?
(In the familiar section there's a rule that says "Only a normal, unmodified animal may become a familiar", can you modify the construct, after making him your familiar?)

Thank you in advance.

Fun questions...

The Ioun Wyrd's Share Iouns ability is listed as a Special Ability of the Ioun Wyrd, itself... yet, the ability in question is worded in a way that it appears to be conditional, only applying when the Ioun Wyrd is taken as a Familiar. I would say the Special Ability is indeed present upon construction, regardless of whether or not its creator has the Familiar class feature, or any intentions of using the Ioun Wyrd as their Familiar, even if they happen to have that class feature.

But the Ioun Wyrd's Share Iouns ability will always exist exactly as it is written. So, no, this Special Ability does not benefit the creator in any way unless the Ioun Wyrd is taken as their Familiar. The Share Iouns ability is worded in a way that it only works between a Familiar and its Master. Share Iouns will exist, yet not help, a random person with Craft Construct that creates a Ioun Wyrd.

If you later pick up the ability to get a Familiar, or change your existing Familiar to an/the Ioun Wyrd... its Share Iouns ability would then be active and benefit you. The ability is always there, though. No modofications are necessary.
