+**What:** The `docs/studio` migration imported only retained artifacts, rewrote them into framework-native templates, turned retained `learn` documents into legacy lessons, kept `specs` outside `discussion/`, and promoted imported open agendas into their own new discussions.
 **Why:** Reconstructing deleted decisions or plans would fabricate workflow history. The retained source set already contained the truth that mattered: one open agenda, zero retained decisions, zero retained plans, and a didactic learn corpus.
 **Trade-offs:** This approach requires explicit editorial normalization and separate migration bookkeeping, but it yields a canonical framework surface without inventing missing history.

+**What:** The `docs/packer` migration imported only retained artifacts, promoted retained open agendas into new discussions, preserved the empty retained sets for decisions and plans, rewrote retained `learn` into legacy lessons, and kept `specs` outside `discussion/`.
 **Why:** The packer domain already had two live agendas and a didactic learn corpus, but no retained decisions or plans. The migration needed to preserve that real operational state instead of fabricating symmetry.
 **Trade-offs:** The pattern keeps workflow truth honest, but it requires explicit editorial rewriting and separate migration bookkeeping before the resulting discussions can continue normally.
