Who is fed, and at what level
Tiers 1 and 2 are absolute claims: the state serves them first and in full while anything is left. Tiers 3 and 4 share the remainder with ordinary retail, pro rata. Ladder, widget 1.3.
Regions
Provisional demand shares. Product moves only between adjacent regions, at most 70% of a region's supply leaves it, and only Moscow may draw from anywhere. Volume is conserved: what the shield keeps, other regions lose.
Repair chain, spares and maintenance
A hit is not repaired from a warehouse. Each unit class has a national pool of spare sets; once it is empty, the next repair waits for manufacture and grey import. Deferred turnarounds raise the chance of unplanned stops until the winter wave runs them.
What moves the number

Who pays
Refinery registry
Anchored constants
Movable only inside a published range. Override them through the scenario JSON with a source; the override is listed in the passport.
The receipt
Computed from the ledger this scenario produces, cumulative to each date, in billions of roubles. Every line is reproducible from the ledger CSV.
Second-order consequences
Order-of-magnitude bands intended to show relative size, not estimates. Where a number could be computed it is in the receipt above; everything here is deliberately left in bands.
Scenario passport
Everything a reader needs to reproduce or dispute this scenario. It travels with every export.
