The slug determines the URL: /posts/<slug>/. Changing it after publication breaks existing links.
The title can be changed freely — it doesn’t affect URLs.
Fields under [extra] that say “inherits from section” get their default from content/posts/_index.md. You only need to set them per-post if you want to override the section default.
