Scope license adjudications to the implementation proven by frozen sources

Scope Habitat license adjudications to the implementation proven by frozen PR bodies, line-level patches, and merge metadata. A merged addition or restoration of accept_license and HAB_LICENSE=accept establishes effective enforcement by Terraform's Habitat provisioner on the merge date. A merged revert removing those paths is a technical control_event with no power edge unless frozen evidence independently changes Chef Software's underlying EULA rights or terms. Preserve the direction and chronology of additions, removals, and restorations, verify quotations against their source envelopes, and never generalize the demonstrated provisioner behavior to every Habitat installation method or infer the effective date or reach of a broader external license policy.
