alex 7c29700ab0 game/sim + app: the output -> money chain, the difficulty multiplier's source, T31
The second chain ComputeBudget needs. The output term (lane N) is a system's
OUTPUT; what the budget and the bankruptcy limits sum is its MONEY, which runs
that total through TradePointsToMoney. Read instruction by instruction, every
range disassembled to the next function start.

The income law is not the output law with a different constant: money per head
is typeIncomeMod / 14000 -- no 1.8, no 500000 -- and it truncates TWICE per
(group, species) row, once inside the per-row term and once after the morale and
addiction factors. Summing the species first and truncating once is wrong on any
colony with more than one species.

The multiplier that was "not on the wire" (formula-gaps.md Q3) resolves to a
three-row table the executable BUILDS IN CODE from .rdata float literals, exactly
like lane N's pop-type table: {int id; float ai[3]; float other[3]}, selected per
player by is-AI && !NPC. Every corpus save carries aidf == 1, whose AI income
column is 1.1f -- the x1.1 the BnkEl oracle measured. Its other two columns are a
fleet-maintenance divisor and a research multiplier, both of which already had a
home in BudgetInputs and no source.

Verified against the 25-record BnkEl oracle, which inverts the stored limit to
the true sum and therefore needs no VM: 6/25 before, 25/25 after. Falsified three
ways -- moving the AI flag off the AI players costs 11 records, moving it onto the
humans costs the other 11, and forcing one species' resource pair on all of them
costs every Zuul record.

app: T31 UpdateBankruptcyLimits now runs the whole roll-up and self-checks it
every run against the BnkEl the input save already carries -- 8 of 8 players on
turn1-state with --ai-player 1. It stays blocked on two things that are not the
formula: ServerPlayer+0xf9 (is this player AI?) is a game-setup input the save
does not carry, and BnkPr needs BANKRUPTCY_PROTECTION_LIMIT_FACTOR from the data
files. Committing it closes nothing on the reference pair -- the limits move
because the CIVILIAN POPULATION grows and that growth is not committed -- so
measured with --commit-blocked=T31 --ai-player 1: 0 closed, 0 REGRESSED, i.e.
209 -> 204 and 108 -> 103 unchanged.

P01 is NOT unblocked, and the roadmap's item 1 was wrong about that: ComputeBudget
takes its per-system money from ComputeOutput with the system's OWN rate sliders,
not from ComputeMaxIncome. Only its projected mode uses the max-income form. On
the turn path the repair pass runs and the unspent-industry and
unspent-terraforming cascades into the money channel are live, so the proof that
both are zero does not apply. The catalog text says so now.

Two things the 25/25 does NOT cover, and they are labelled in the code: the
suitability money cost is multiplied by zero on every corpus colony (all sit at
their species' ideal), and the slave, addiction, morale, station and
capacity-surplus branches are unexercised.
