# Derived Preview

`POST /api/v1/analysis/derived-preview`

## Request

- Base URL: `https://api.cohearence.app` (the document declares no server; this is the origin it was published from)
- URL: `https://api.cohearence.app/api/v1/analysis/derived-preview`
- Auth: HTTP bearer

Evaluate a derived spec WITHOUT persisting it — the builder's live preview.

Runs the exact evaluator the analysis endpoints use, so what the user sees
at creation is literally what analysis will show. Returns the evaluated
points, each input's own series (for the faint underlay), coverage counts,
the plain-English read-back sentence, and the inferred type/unit.

## Request body

- object

## Response `200`
