Struct TickContext 

pub struct TickContext<'a, M> {
    pub gm: &'a mut M,
    pub client: &'a mut CommandClient,
    pub cycle: u64,
}

Per-tick context passed to the control program by the framework.

TickContext bundles all per-cycle data into a single struct so that the ControlProgram::process_tick signature stays stable as new fields are added in the future (e.g., delta time, diagnostics).

The framework constructs a fresh TickContext each cycle, calls CommandClient::poll before handing it to the program, and writes the memory back to shared memory after process_tick returns.

Fields

gm: &'a mut M

Mutable reference to the local shared memory copy.

client: &'a mut CommandClient

IPC command client for communicating with external modules.

cycle: u64

Current cycle number (starts at 1, increments each tick).
