Critical spare-parts resilience network

// Compare alternative sourcing and repair loops without claiming the diagram is a logistics optimiser.
// Synthetic worked example: all entities, schedules and measurements are illustrative.
// Every string below is EXAMPLE text from a fictional model: replace it.
// Replace assumptions and inputs before applying this model to actual work.
