A portfolio claim is weak until someone else can click it. Store listings, live sites, and working demos are the proof.
The rule
If a project cannot be opened, it does not go on the public reference list. Internal operations systems stay in conversation, not in a locked slide.
What that looks like
Fikeyword and FiPhotoPro have store pages. Client sites and demos stay public even when the original organization later closed.
That constraint keeps the site honest.
