Module interp 

The interpolation namespace (ARCHITECTURE.md §1).

Env values reference a namespace evaluated per instance per substrate. $PORT is deliberately not an interpolation reference — it is injected by the local substrate into run commands only, so the tokenizer here only understands ${...} forms.

Structs

Namespace

The values a substrate supplies for one instance. Built per instance per substrate; resolution itself is substrate-blind.

Enums

Reference

A parsed ${...} reference.

Functions

references

Extract every ${...} reference from a value.

resolve

Substitute every ${...} in value from the namespace.
