  "description": "Enable service developers and operators to evolve and apply the workplace persistence schema consistently across fresh workspaces and deployed instances.",
  "user_problem": "Service teams need database changes to be ordered, repeatable, and compatible across local and deployed environments.",
  "expected_value": "Reduces schema drift and makes migration failure visible before the service accepts traffic.",
  "scope": "Includes the Prisma schema, ordered migrations, client generation, development migration workflow, and production migration gate.",
  "exclusions": [
    "End-user product behavior and solution or release authorization are outside these engineering Features."
  ],
  "acceptance_outcomes": [
    "The database contract is versioned in one Prisma schema.",
    "Ordered migrations create and evolve user, settings, scene, and seat data.",
    "Local service workflows generate the Prisma client and apply development migrations.",
