Question#
Who owns the Study & Deconstruction Workspace experience, study substrate, evidence substrate, and analysis lenses?
Recommendation#
Adopt proposal §3.1 verbatim: Yemaya owns the creator-facing experience and project transfer; Nisaba owns durable study/notebook semantics; Sophia owns evidence anchors, provenance, and confidence-bearing claims; each analysis lens stays with its accountable domain (Hathor, Aja, Euterpe, Aglaea, Bellona+runtimes, Metis, Isis, Oshun, Iris, Neith/Maya per §3.2).
Options considered#
- Hathor as sole owner — rejected by the proposal: overfits narrative/game design, leaves camera/motion/sound/costume/learning under-composed.
- New standalone domain — rejected: duplicates Studio shell, Library, and notebook infrastructure Oshun/Nisaba already own.
Consequences#
- YSD-0121 encodes the boundaries in Nx tags, dependency constraints, CODEOWNERS, and architecture tests.
- The §3.2 responsibility matrix becomes the adapter map for Sections 0.3 and 6.
Machine-enforced outcome (once approved)#
Nx tag/dependency constraints + architecture tests (YSD-0121, YSD-0164) reject cross-boundary imports.
