Context#

The Period cell spans 1930s, 1947, and 1968 eras over a shared city. Vehicles, fashion, radio, signage, slang, lighting, and prop density must shift by era without duplicating the entire world.

Decision#

V5 uses three period-authenticity bundles for 1930s, 1947, and 1968. Bundles drive Data Layer swaps, NPC presentation, vehicle pools, UI flavor, radio content, and era validation.

Consequences#

  • Period content must declare an era bundle.
  • Runtime swaps are data-driven through V5PeriodAuth.
  • Certification and cultural-review checks can audit each era separately.
