;;; Commentary:
;; Tests for the two picker commands that resolve names to ids:
;; `pearl-edit-assignee' and `pearl-edit-labels'. As save-model-v2
;; buffer-editors they write the LINEAR-ASSIGNEE / LABELS drawer (and the live
;; id sets) but do NOT push -- the change reconciles at the next save (the push
;; path is covered in test-pearl-save). The resolver is stubbed.
