In plain English
This page covers the high-risk pattern where small adapters, routes, memory, evaluators, and descendants can reinforce each other across time. It is a risk model, not a build guide.
- Why this matters: AI risk can come from the whole arrangement, not one obvious model.
- What to look for: data, memory, routes, adapters, tools, evaluators, updates, and rollback paths.
- Technical version below: the expert terminology remains available and is linked through the glossary.
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 evaluatorA system that judges whether an AI output or candidate is acceptable. Open glossary definition scores may keep choosing components with a particular behavioral signature.
If those choices influence future candidate generationCreating a proposed new model, adapter, prompt, route, test, or policy. Open glossary definition, routing becomes a reproduction channel.
Reproduction by preference
A router can preserve a behavior without copying any weights. It can repeatedly select descendants, adapterA small add-on that changes or specializes model behavior. Open glossary definition 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 persistenceA behavior remains present even though the original artifact that expressed it has been removed. Open glossary definition 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 rollbackReturning a system to an earlier known state. Open glossary definition 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.
