Struct DataSystemRegistration 

pub struct DataSystemRegistration {
    pub name: &'static str,
    pub phase: TickPhase,
    pub run: fn(&mut World, &Runtime, &mut OutputDeck),
    pub order_hint: i32,
    pub runs_after: &'static [&'static str],
}

Registration entry for a [DataSystem].

One entry per system, submitted via inventory::submit! at link time. The dispatcher in khora-control discovers all entries, groups them by TickPhase, topologically sorts within a phase using runs_after (with order_hint as tie-breaker), and invokes them sequentially.

Fields

name: &'static str

Stable identifier — used for runs_after references and telemetry.

phase: TickPhase

Phase this system belongs to.

run: fn(&mut World, &Runtime, &mut OutputDeck)

The function to invoke on (&mut World, &Runtime, &mut OutputDeck).

• The Runtime bundle lets a system fetch typed services / backends / resources it needs (EcsMaintenance, GraphicsDevice, …).
• The OutputDeck is the per-tick typed deck the lanes wrote into during the CLAD descent. Maintenance-phase systems use deck.take::<MyWriteback>() to drain typed writeback slots and apply them to ECS components. Pre-scheduler phases receive an empty (transient) deck — systems that don’t need it just ignore the third arg.

order_hint: i32

Tie-breaker used to order systems within a phase when no explicit runs_after ordering applies. Lower runs first. Default 0.

runs_after: &'static [&'static str]

Names of systems within the same phase that must run before this one. Used to topologically sort the phase. Empty by default.
