sb-ship — graduate, preserving history

Event-triggered when an Explore iteration meets the graduation gate. The one rule that matters: preserve the experiment — cp, never git mv. The Explore story stays as design history; git mv here is the destructive bug propagate-workflow.md exists to prevent. Load references/propagate-workflow.md before any Ship action — it's the only reference this skill needs; Do NOT load the sb-wrappers/sb-audit refs (lifecycle, galleries, composition) for a Ship.

Decide the path (ask yourself)

• Did the Explore define its own component file, or iterate on an existing one? → Path A vs Path B.
• Path B: evolve in place (B1) or keep V1 in _legacy/ (B2)? B2 only when V1 still has live callsites needing a migration window.
• Did the import path change? If yes → ast-grep callsites. If not → skip it.
• Other tagged stories that should flip? (a Compare decision:pending → decision:chosen + winner.)
