Why these stay. The verdict is coverage aware. A clean result would read "Insufficient coverage", not "Safe", precisely because these rules did not run. Hiding them would let a shallow scan look as thorough as a deep one.

How this server was scanned

The method behind this result was not recorded: the scan predates it. How deep it reached is unknown, and is not implied by anything on this page.

Observed behaviorexecuted in sandbox

Declared tool hints vs. what each tool was actually observed to do when executed in our egress-denied sandbox - plus any witnessed tool→tool flow within this one server. This is not cross-server toxic flow, which composes several servers in one config.

Observed behavior not captured for this scan

No observed-behavior record is on file for this server's latest scan.

This is a coverage gap - we did not execute this server’s tools in the sandbox for this scan. It is not a clean result and is not scored as one. To see how observed behavior is rendered when a run does happen, view the illustrative cross-server toxic flow.

Intrinsic here, config-scoped elsewheredual unit

Everything on this page — the verdict, every finding — is agenticfabricationnetwork.ai assessed on its own. That is its intrinsic posture. Whether it becomes one leg of a cross-server toxic flow is a different, config-scoped question: it depends on which other servers share its client config, and no verdict on this page changes for it.
