algeon-datafusion 0.1.2

//! Stable backend observability contracts for application exporters.
//!
//! Re-exports engine snapshot and metric types for application telemetry
//! exporters. Observation snapshots are queried through [`crate::backend::AlgeonGpuBackend`].
//! Device ledgers record admission grants, while TSV reports and DataFusion
//! execution metrics project from runtime observation snapshots.
