# Legacy B-roll Runtime Planner Treat this stage as read-only compatibility for old production records. Do not dispatch it in a normal v1 production, do not create a new plan here, and do not reinterpret or edit an existing plan. In v1 the Parent runs `scripts/plan-runtime.mjs` directly with the Director's validated Recipes, runtime selection, narrative envelope, visual system, and new production root. The script validates those inputs, writes the immutable runtime plan, and writes one minimal assignment packet per authoring unit. When reading a legacy handoff, verify only that: - its plan JSON passes `scripts/validate-runtime-plan.mjs` using `../../references/runtime/capability-matrix.json`; - every Director shot appears exactly once in a backend block and authoring unit; - time coverage is continuous and unit boundaries contain whole shots; - evidence and warnings are preserved without subjective reinterpretation. Return a compact recovery report to the Parent with the last trustworthy plan identity, available artifacts, concrete mismatch, and safest next owner. Do not repair the record, convert it into a v1 plan, or continue an old Planner → Integrator → Render chain as though it were the current workflow.
