# C20 · A trail worth keeping

## Boundary

Keeping a feature is legitimate; no annual mastery or local result is claimed.

## Complete source

Fictional folio contains an owner-chosen soil-role card citing F3 and an empty local-observation page. It is ready for a private reader but not a completed field study.

## Id

C20

## Invitation

Give one supported feature to keep and a new question.

## Next try

Choose one small future evidence job with adult review and a different product, such as a water-role bookmark.

## Ordinary possible response

I will keep the source-linked habitat role and leave local organism observations open.
