// DB-backed integration coverage for the shared ListGrantsWithDelivery query
// (ux-honest-surfaces design decision 1) end to end: real IssueGrant / Extend
// / Revoke flows against a real Postgres, read back through both the
// org-detail composite and the grants index, asserting the two surfaces
// agree on delivery-state wording and that supersession lineage is visible.
//
// Also locks in the derivation's precise "superseded" boundary: a grant
// whose provision simply ended with no recorded successor (a plain revoke)
// renders "Inactive", not "Superseded" -- "Superseded" is reserved for the
// case a replacing grant is actually on record (extends_grant_id), because
// the UI must be able to name what replaced a superseded row.
