Goal: the authoritative simulation loop and the single-writer model.
Scope / deliverables:
engine:sim: fixed 20 TPS tick + Box2D subticks (e.g. 3×1/60) inside each tick; render interpolation via partialTick.TickScheduler: scheduled tile ticks (delay+priority) + random ticks (randomTickSpeed).- Command bus — the only way to mutate world/ECS (single writer).
- Context parameters:
WorldContext (read), CommandContext (write), ClockContext{gameTick, partialTick, seeded random}, EcsContext.
SessionScope on coroutines; heavy pure work off-thread returning commands.- Migrate the old
*ControllerTask periodics here as tick phases / scheduled / random ticks.
Definition of Done: deterministic tick; mutations only via commands; golden tests of tick/scheduler behavior; determinism test (same seed+commands → same snapshot).
Depends on: E1
