Path 3 — Assemble from stored sections

Beta ← Back to Guided Synthesis overview Use this when you don’t have a template that matches your need, but you do have the sections. List the sections you want, in the order they should appear, and supply template-level instructions. The response includes the new auto-generated template aggregate — keep its templateId to reuse the same composition on subsequent calls. The aggregate is retained for 30 days only (see Auto-generated template aggregates — 30-day retention); convert it into a permanent project-owned template if you want long-lived reuse.

Behavior notes

sectionRefs is order-significant — sections appear in the rendered document in declaration order.
Each sectionRef resolves to the section’s published version unless you pin sectionVersionId.
overrides on a sectionRef follow the same partial/wholesale rules as Path 2.

When to use this path

Scenario	Why Path 3
EHR-field-driven note where the section set varies per encounter	Compose the right sections per call without authoring a template per combination.
One document built from a few Corti Standard sections	Skip the template authoring step entirely. The auto-generated aggregate is your “receipt.”
Customer-specific composition that you may eventually promote to a permanent template	Run Path 3 first; if the same composition recurs, convert the aggregate into a project-owned template via the retention workaround.
