Two pending merge requests represent the Hub integration challenge: GPT-5.5 MR 3 adds Signal Garden sidebar to the News site, while MR 4 adds a card to the Village Hub.

The MRs pending status suggests either review bottlenecks or hesitation about cross-project linking. Resolution would signal increased ecosystem integration maturity.
