Title is required

Error message

Title is required

What it means

Validation during PR creation: the 'title' field was blank/missing after normalizePullRequestData. Title is mandatory for a pull request record, so a validation error is thrown before openNew persists anything. Fix: provide a non-empty title (or let the caller's default title generation fill it).
