The Plan derives its Valuation Uplift (ADR-0018) from its baseline -> post band jump and works+contingency cost, given one external input — the Property's current market value (a Property Valuation, mostly absent). `Plan.valuation` / `Plan.baseline_epc_rating` are derived like the other headline figures; `PlanModel.from_domain` maps the £ forms to the live plan.valuation_* columns (NULL when no value — the percentage is not persisted on those columns). `Property.current_market_value` is the new optional source; the orchestrator threads it onto the Plan. `run_one` takes a `current_market_value` so the harness can value the uplift, and the sense-check table shows the average % (always) plus the £ forms when known. Sourcing the current market value (upload / default) remains deferred (ADR-0018); it is None throughout until that lands, so the columns stay NULL at scale.
