Plain language
A shared shelf where every accepted answer is stored for all the other participants to read and copy.
As stated in the literature
A shared artifact store auto-populated with any submission that passed the grader; because acceptance implied publication, it converted a single successful exploit into a reference example for the whole swarm.
Also called: shared knowledge library
Why it matters: Sharing accepted work speeds everyone up, but if acceptance is automatic then a single bad answer that slipped past the checker becomes a template the whole group learns from.
For example, once one participant's answer is marked correct it lands on a shared shelf where everyone else can read it and copy the approach.
