constexpr int	flux_hal::kFluxCpuNoAffinity = -1
	No CPU affinity (tskNO_AFFINITY / scheduler chooses).

constexpr int	flux_hal::kFluxCpuRealtime = 1
	Logical core for high-rate real-time loops (pressure, manifold, safety).

Detailed Description

Logical CPU indices for FreeRTOS task affinity on the Flux board.

Application and middleware pass these integers to BaseThread / os_thread_create_pinned (via hf-core OsAbstraction). They are HAL board integration policy for the current target, not portable silicon constants: the mapping from logical index to vendor core names is documented in the Flux V1 board / integration handbook (e.g. on dual-core ESP32-S3, kFluxCpuHostIo is core 0 and kFluxCpuRealtime is core 1, consistent with Espressif IDF “PRO_CPU” / “APP_CPU” terminology).

On single-core builds, the RTOS wrapper ignores affinity; passing any value here remains safe.
