What does it take for input addressed path to be added to the store?

[roberth]

Problem

What's the policy for adding an input addressed store path? What purpose does it serve?

How does it relate to content addressed paths?

Or: how does trust work?

Checklist

• checked latest Nix manual (source)
  • conf-file.md: not a single reference. I need a single section to link to
  • verify.md: only about signatures
• checked open documentation issues and pull requests for possible duplicates

Proposal

This should be documented centrally so that other documentation can refer to it. Related terms/features that should link to the new section about trust:

• substitution
• fetchClosure
• nix.conf
• make-content-addressed (avoids need for trust)
