Walkthrough

A GitHub Actions workflow now includes a pre-check step to verify that SUPABASE_DB_URL is set from secrets, failing if empty or logging its length if present. The backup script step explicitly exports this variable before execution, creating conditional control flow.

Changes

Cohort / File(s)	Summary
Workflow validation and export \.github/workflows/backup\.yml	Added "Verify SUPABASE_DB_URL is set" step that validates the presence of the secret and errors if missing. Modified "Run backup script" step to explicitly export SUPABASE_DB_URL before executing backup.sh.

Poem

🐰 A rabbit hops through workflows bright,
Checks secrets gently left and right,
"Is DB_URL here?" we cry with care,
Before backup runs—let's verify there!
