Find the shared dependency behind the second supplier

Edit supplier-plan.json with selected booleans for ALL option IDs, evidenceRefs arrays keyed by ALL options and allocations[event][service][option] nonnegative integers (include every key; unselected options receive zero). Select at most one mode per supplier, with at < contractUntil. Every selected option needs both required controls from referenced verified exact-option records satisfying from <= at < until. Total selected reservation cost must fit budget. A mode is usable only when its contract/assurance is current, its supplier mode is unique, the portfolio is funded and NONE of its root or transitive ALL-required dependencies fails in that event. Unselected/unsupported/down modes receive no delivery credit and must not receive positive allocations. Each option's capacity is shared by both services in the same event. An overcapacity option earns no delivery credit for either service; a service allocated above its demand earns none for that service. Meet every event-specific service minimum AND keep weightedLossNumerator <= riskLimit. That numerator sums (demand-credited service units)*service.loss*event.weight across ALL events/services; its denominator is 1000, not a supplier independence assumption. Report totalCost, dependencyClosure keyed by ALL options (complete selected root+transitive IDs, empty for unselected), served[event][service] and weightedLossNumerator. Report integer or null numeric values while unfinished. Closure arrays have set meaning; allocations are actual service units, not standby labels. Preserve working reservations and evidence while repairing a remaining allocation or report without Reset.
