# IonQ x DARPA revision history

Append-only Arc G field-change log. Forward-only honesty: events accrue from Arc G adoption.

Partnership: [IonQ x DARPA](/partnerships/ionq-darpa-quantum-benchmarking.md)

_No events on file. Arc G is forward-only; the recorded event log accrues from Arc G adoption (2026-06-04). For the current state of this partnership, see the partnership page._

## Forward-only note

Arc G is forward-only. The event log accrues from the Arc G adoption point. Fields with no events post-baseline equal the current cached value and are not independently verified at any prior date.
