What happens to a stranger's pull request here, in the Porchlamp snapshot of 17 October 2026.

For ledger/ledger, the reply time and the share with no reply within 14 days both have too small a sample to measure (0 and 7 pull requests counted; 10 needed). It ranks 2,933 of 3,219 overall. It is not ranked for first-time contributors: not enough evidence to show under this lens.
