# Weekly sweep: send win-back emails to inactive Basic/Pro orgs (30-90d stale)

`POST /internal/cron/winback`

Weekly cron targeting paid orgs whose most-recent `api_keys.last_used_at`
is between 30 and 90 days ago.

Audience (audit R15):
  - status='active' (skip canceled / past_due / payment_at_risk)
  - tier IN ('basic', 'pro')  — free-tier excluded: free cooling-off
    is evaluation behavior, not churn, and over-emailing degrades
    sender reputation.
  - max(api_keys.last_used_at) between 30 and 90 days ago.

Upper bound (90d) prevents cold-contacting fully abandoned trials
indefinitely. Frequency cap (30d) in send.py means a user stuck
in the 30-90 band gets at most one win-back every 30 days, not
once per weekly cron fire.
