# Validate upload_template.py + send_batch.py against the LOCAL docker stack.
# Catches script bugs before we point them at prod.
#
# Prerequisites:
#   1. Local stack running: docker compose ps shows app + postgres Up
#   2. Admin user created (you said you did this earlier)
#   3. API token generated in the local UI:
#        Settings -> API -> copy the token
#   4. Export it:
#        export DOCUSEAL_API_KEY=<paste-token>
#   5. (Optional) export TEST_RECIPIENT=<your-real-email> to receive the test invite.
#      Without SMTP configured locally, the email won't send -- but the API call
#      still creates the submission, which exercises send_batch.py end-to-end.
#
# Usage: deploy/deliverability/local_validate.sh
