A todo node's key and text were hand-expanded `{field}` strings. They are now Jinja templates rendered through the new hive-template crate (minijinja, an unknown variable is an error), and the controller's save check reads the variables the template uses. The flows document is version 2; a version 1 document reads as version 2 with each `{field}` converted to `{{ field }}`, and the next save writes it.

# hive-template
|
|
|
|
The one template language the hyperhive workspace renders with: Jinja, through
|
|
[`minijinja`](https://crates.io/crates/minijinja). A value is `{{ name }}`, a
|
|
block is `{% if cond %}...{% endif %}`, and a lone `{` or `}` stays plain text.
|
|
|
|
- **`render(template, &context)`**: the text, or a message when the template
|
|
does not parse or names a variable the context lacks. An unknown variable is
|
|
an error, never an empty string.
|
|
- **`variables(template)`**: the variables the template reads, so a caller can
|
|
refuse an unknown field when the template is saved instead of when it renders.

Used by the notification router's flow templates (`swarm-notify-router`,
|
|
`swarm-wire`).
