| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Mass Production (mass_production) | commercial_or_scaling_dependency | 58% | expert_inference | Standardized container production supports scaling but should not be modeled as the defining prerequisite for the 1956 shipping-system anchor. |
|
| Steel Production (steel_production) | required | 78% | expert_inference | The 1956 Ideal X system used metal containers; steel production is a material dependency for the scoped container-shipping system. |
|
| Railroads (railroads) | commercial_or_scaling_dependency | 58% | expert_inference | Rail integration is important for later intermodal networks but not required for the first modern commercial container-ship voyage. |
|
| Internal Combustion Engine (internal_combustion_engine) | commercial_or_scaling_dependency | 64% | expert_inference | Truck-to-ship intermodal movement made containerization commercially useful, but engines are scaling and operating infrastructure rather than the container concept itself. |
|
| Steel Ships (steel_ships) | required | 80% | expert_inference | The first modern commercial container-shipping voyage used a converted tanker, so steel ships are a hard dependency for the shipping-system scope. |
|
| Crane & Lifting Devices (crane_lifting_devices) | commercial_or_scaling_dependency | 66% | expert_inference | Container handling requires lifting infrastructure at commercial scale, but cranes are not the date-defining invention of the 1956 voyage. |
|
| Logistics & Supply Lines (logistics_supply_lines) | common_dependency | 56% | expert_inference | Containerization reorganized freight logistics; earlier logistics practice is contextual background rather than a hard technical prerequisite. |
