Fact-checking as a service Preview
researchteam exposes a machine-callable capability other teams consume: verify one technical claim against current sources.
A capability is a named service a team declares and other teams can consume. research.factcheck verifies a single technical claim against current sources, handled by the foundations-researcher's key-sources lens. devteam's code-review objective declares that it consumes it — which is what lets a reviewer check a factual assertion instead of asserting one back.
Marked preview for a reason
It is real, declared and wired, and it has exactly one declared consumer. Inter-team capability calls are the newest part of the composition model and the least exercised in the field, so the honest label is preview rather than shipped.
