You saw that a PR with a fix being made available to Nixpkgs. It’s approved! It’s merged! But when you run nix flake update, your changes are nowhere to be found. Where did they go?

Using the real-world example of PR #451386 (Ruby patches for GCC 15), I’ll show you how to navigate the "Staging" labyrinth. We’ll decode the CONTRIBUTING.md guidelines, learn why some PRs take the "slow lane," and master the PR Tracker to see exactly when your code hits the notable branches.
