Overview

Serdes type for a replace_with value: a template String with {column} placeholders, rendered as text, or a non-String JSON scalar used verbatim so a column that is not text keeps its type (in MongoDB, its BSON type).

PERMITTED = 
[String, Integer, Float].freeze
PLACEHOLDER =

What counts as a {column} placeholder: an empty brace pair names no column, which is what lets {} be an empty-JSON mask. One definition, shared by the adapters that parse a template and the generator that must avoid emitting one — keep it capture-free, since the splitter's scan reads whole matches.
