Date-range filter (v0.2.1)

Stack any of created_after, created_before, updated_after, updated_before (all epoch milliseconds, inclusive bounds) onto a GET /api/memories call. Works alongside q, namespace, and metadata_filter.

# "memories from the last 7 days"
WEEK_AGO=$(node -e "console.log(Date.now() - 7*24*60*60*1000)")
curl -H "Authorization: Bearer mnu_..." \
  "https://mnueron.com/api/memories?created_after=$WEEK_AGO"

# SDK equivalent (Python)
from mnueron import Mnueron
import time

mem = Mnueron(api_key="mnu_...")
week_ago = int(time.time() * 1000) - 7 * 24 * 3600 * 1000
results = mem.list(created_after=week_ago, limit=50)

Common use cases: "what did we work on this week?" queries, scheduled digest generation, time-windowed audits.
