Documented actor use

Explicit actor-to-software uses relationships in the pinned ATT&CK source. These links are historical behavior context, not attribution of current events.

Technique-specific simulations and detections

Detection links describe the associated behavior, not independently verified tool-specific signatures.

Telemetry context

Derived from the explicitly linked TTPs; not proof of sensor coverage for this tool.
