Module template 

Workflow templates: {{path}} interpolation with dotted / JSON-pointer paths and {{path | default}} over the run data (inputs, run, steps.<id>.output, vars, memory.<key>, item, index, batch, env), plus CEL: expressions over the same names (feature cel; a non-CEL build refuses them at validation). Dependency-free.

Rules: a string that is exactly one {{path}} yields the value itself (typed); any other string interpolates (strings raw, other values as JSON); objects and arrays render recursively; a missing path with no default is an error (the step takes its error edge rather than running with a silently-wrong shape).

Functions

lookup

Look up a dotted or JSON-pointer path in the data.

referenced_roots

Every {{path}} root referenced by a template (steps, vars, …) — for validation / dependency hints.

render

Render template over data.

render_str

Render a string template: CEL: expression, a lone {{path}} (typed), or interpolation.

Type Aliases

Data

The named inputs of a render: the root names a template may reference, mapped to their values. A name absent from this map is a missing path, so what the caller puts here is exactly the vocabulary a template may use.
