Checklists are versioned
Like an inspection template, a checklist here has a draft and a published version. A plan always copies the version in force at the moment it pulls the checklist onto its own task list — publishing a correction here never rewrites a plan that has already copied it. To change what plans copy from now on, take a draft, edit its steps — reordered by dragging — and publish it.A checklist with nothing published cannot be pulled onto a plan at all: there is no version in
force to copy. Open it and publish the draft first.
Who is using this one
Expand a checklist to see which plans have pulled it. Worth checking before editing a widely-used one, and before deleting it — a checklist still in use should usually be retired instead.Retiring versus removing
Retire (is_active off) takes a checklist out of the picker offered when building a plan, and
leaves every plan already built from it untouched — the ordinary end of a checklist’s working life.
Delete is a soft delete on the checklist’s own row. Plans that already copied it keep their
steps; they simply stop being able to tell whether the library’s version has since moved on.
