Availability is not a routing strategy
Round-robin and shared inboxes break the moment volume or risk increases. A legal summary routed to a designer is not faster — it is dangerous. 4loop routes by domain expertise, risk tier, and the kind of decision required.
Deterministic rules mean the same output type always lands with reviewers who are qualified to evaluate it, which builds trust in the pipeline over time.
Rules you can explain to compliance
Routing logic should be inspectable: which skill tags, categories, or risk labels triggered which queue. That transparency helps security, legal, and ops teams sign off on agent scope without treating review as a black box.
Works for solo and team modes
Solo users still benefit from routing to the right external expert network. Teams map outputs to internal roles — engineering, design, DevOps, compliance — without maintaining manual assignment spreadsheets.
