## Question

Where does the workspace mount in Oshun Studio?

## Recommendation

Adopt /studio/study (proposal §3.3 preferred placement): the workspace is a
cross-domain composition entered from the global "Study" nav item; nesting it
under /studio/yemaya would brand a multi-domain product as one domain's feature
and lengthen every deep link.

## Options considered

- /studio/yemaya/study — rejected: buries Nisaba/Sophia rails under Yemaya
  branding; complicates the migration story for the standalone Yemaya apps.

## Consequences

- YSD-1002 scaffolds apps/oshun/web/src/app/studio/study/.
- Deep links, analytics route names, and the Study nav entry use /studio/study;
  no redirects needed since the route is new.
- If later renamed, YSD-0122 must be superseded with a redirect plan.

## Machine-enforced outcome (once approved)

Route scaffold lands only at the approved path; traceability check and
Playwright journeys pin the URL.
