An entry stored subject_id, assurance and evidence_ref but nothing about
what kind of principal bound the approval, and subject_id is a naming
convention rather than a verified claim. /entries is not restricted by
principal type — only /consume is — and the approval-engine-operator
client holds approval:approve, so a service can supply approver evidence
today. Whether it may is gate-house doctrine; that it is legible is ours.
Add entries.principal_type, populate it from the verified token, surface
it on the object and the audit evidence path (not the claim, which stays
least-disclosure), and migrate v3 stores leaving legacy rows null rather
than back-filling a claim nobody made.
Also corrects two statements in the requirements issued to
informed-decision: agent tokens are not barred from approval:approve, and
an empty assurance object is accepted rather than refused.
