/**
 * Replaces a rule whole. `scope` is required and `role` is not, mirroring the
 * discovery document, which marks `role` required for `acl.insert` alone. For
 * changing only the role and leaving the rest alone, see patch_acl_rule.
 *
 * This is a PUT, which COVERAGE.md otherwise says the suite skips in favor of
 * patch. The reason that policy exists (a full-resource PUT over a lossy
 * projection clobbers the fields the projection dropped) does not apply here:
 * `role` and `scope` are the whole writable surface of an ACL rule, and both
 * are projected, so nothing can be clobbered by omission.
 *
 * Destructive despite the rubric's "updates are not destructive" default
 * (the `update_event` precedent), following instead the standing-side-effect
 * cluster of `gmail/create_filter` and `sheets/add_protected_range`: this
 * update changes who can reach a calendar, the access it confers persists
 * until something revokes it, and it can escalate a scope to `owner`, which
 * confers control over the calendar's own sharing.
 *
 * Open-world and NOT idempotent on the precedent of the sends
 * (`gmail/send_message`, `gmail/send_draft`), because `sendNotifications`
 * defaults to true at Google: a replay with identical arguments can send
 * another round of sharing notifications, which is an additional effect on
 * the environment.
 * The hint describes the riskiest accepted input, and `src/lib/server.ts`
 * reads `idempotentHint` as permission to silently retry after a credential
 * refresh. Access removal sends no sharing notifications.
