What did the source declare before the tool ran?

Why this evidence matters

Attach verified source-rights evidence to URL-bearing tool calls. Your gateway still owns the decision and enforcement.

A source URL and event time alone may not preserve what the site exposed at observation time. AcqPath records the result and uncertainty for review, not a licence or legal clearance.

Start in Observe mode

Extract the selected source URL and explicit intended purpose from the gateway context. Resolve evidence in parallel with the existing tool call and write the resolution to the gateway audit stream.

Do not make AcqPath the first enforcement point. Prove the evidence gap at the 25-event / 6-hour decision gate, or earlier if a material signal appears, then move to Advise or partner-owned Enforce if useful.

Policy handoff

When the partner is ready, serialize the same resolution into an attested policy input. The existing policy engine decides allow, deny, warn or review.
