The eleven forwarding members added last commit are gone; callers now read the
data directly through FactoryQueries.h. Simulation and ArenaSimulation expose
getFactoryState() so the UI, the balancing view and the tests can reach it.
isQueuedForDeconstruction joined the free functions along the way — it only
reaches findBuilding, so it was state-pure too.
No facade was introduced. The chained form was the reason one looked attractive,
but rewriting sim.getBuildings().findBuilding(id) to findBuilding(sim.getFactoryState(), id)
turned out to be mechanical, and the result says which data is read rather than
which system happens to own it.
BuildingSystem.cpp is down to 1735 lines and no longer answers questions about
the factory — it only changes it. What remains on it are the mutators, the tick
phases, and the queries that also need GameConfig.
Verified with a golden-checksum capture before and after — all four sample ticks
identical.

Simulation (and ArenaSimulation in the balancing tool) now owns the factory's
world data; BuildingSystem holds a reference to it. This is what lets the systems
that operate on the data be handed the same state — phase 3's construction and
deconstruction systems, and later the ecs/system/ classes that today take a
BuildingSystem& only to query it.
reset() clears the state alongside m_admin and m_beltSystem, matching how the
subsystems were already rebuilt from scratch.
Falls short of the tick-argument form I sketched: BuildingSystem still reaches
the data through a member reference rather than a parameter. Making it truly
stateless means the const query surface has to find the data some other way, and
that surface is large — findBuilding alone has 64 call sites, with findSite,
getAllBuildings, getAllSites, isTileOccupied and the rest behind it. Doing that
needs a queries facade behind Simulation::getBuildings() so the callers do not
all move, which is its own decision rather than a side effect of this one.
The constructor gains a parameter, so the four owners and the three test fixtures
that build a BuildingSystem directly are updated; the 33 files that only use one
are untouched.
Verified with a golden-checksum capture before and after — all four sample ticks
identical.
