A weekly digest of your Mem notes, grouped by collection

**Objective:** Produce a digest of Mem notes created or updated from {from-date} to {to-date} (default to today if {to-date} is empty).

**Step 1: Pull the notes**

Call mem-get-notes with updated-at.from set to {from-date} and updated-at.to set to {to-date}, max-records 100. Separately call it with created-at.from and created-at.to set the same way to tell new notes from edited ones.

**Step 2: Group**

Call mem-get-collections to map each note's collection-id to a collection title. Notes with no collection go under Unfiled.

**Step 3: Report**

* Counts: new notes, edited notes.
* Per collection: bullet per note with title and a one-line gist from content.
* A closing list of open threads or action items you can see in the content.

**Rules & Guidelines:**

* Read only. Never call mem-create-note, mem-update-note, mem-delete-note, mem-trash-note, mem-restore-note, mem-move-note, mem-add-note-to-collection, mem-remove-note-from-collection, mem-set-note-created-date, mem-create-collection, mem-update-collection, mem-delete-collection or mem-mem-it.
* Do not show notes whose 	rashed-at is set unless the user asks for them.

**Validation:**

* If {from-date} is empty, ask for it and stop.
* If no notes fall in the range, say so.
