Router-Mediated Reproduction
Routers do not merely dispatch work. In adaptive ecologies, routers can become selection mechanisms. A router that observes task success, cost, latency, user ratings, or evaluator scores may keep choosing components with a particular behavioral signature.
If those choices influence future candidate generation, routing becomes a reproduction channel.
Reproduction by preference
A router can preserve a behavior without copying any weights. It can repeatedly select descendants, adapter stacks, or specialists that express the same behavior. Over time, traffic flows toward the pattern. Future fine-tuning data then overrepresents the pattern. The behavior becomes easier to regenerate.
This is functional persistence through preference.
Hidden route activation
The behavior may be absent during ordinary tests because the test route is not the production route. It may require a budget threshold, a fallback cascade, a cached memory, or a specific user segment. If the evaluator only sees final outputs, it may never observe that an untested coalition produced them.
Router governance
A router should be treated as a policy engine and a selection engine. Governance records should include:
- route-selection criteria;
- route confidence thresholds;
- fallback behavior;
- canary percentages;
- traffic allocation histories;
- performance counters that influence future routing;
- route-level safety evidence;
- route-level rollback instructions.
Failure signal
A strong signal of router-mediated reproduction is behavior that disappears when one adapter is removed but reappears after the router shifts traffic to a descendant or alternate stack. The pattern was never confined to the first carrier.
