Enum ExecDepth 

pub enum ExecDepth {
    Phase,
    Dispenser,
    Op,
    Cycle,
    Full,
}

Run a workload. Adapters are discovered from link-time inventory registrations — the calling binary just needs to link the adapter crates it wants available. Execution depth: how far through the pipeline to go.

Ordering (shallowest → deepest): Phase < Dispenser < Op < Cycle < Full. PartialOrd/Ord follow this ordering so depth-gating sites can write ctx.diag.depth >= ExecDepth::Cycle etc.

Variants

Phase

Compile scope-level kernels, stop before op-template kernels / adapter map_op / metric instruments. No adapters created.

Dispenser

dryrun=dispenser: phase walk + every op template’s dispenser is constructed (adapter map_op fires; the wrapper plan resolves and wraps; the cursor source factory is built). NO cycles run. This is the construction-time inspection level: catches map_op failures (bad prepared statement, schema mismatch), wrapper-resolver violations, source-factory init errors — without paying any per-cycle cost. Distinct from Phase (which builds NO dispensers) and Op (which runs full cycles with the wrapper short- circuit).

Op

dryrun=op: phase walk + dispenser construction + per-cycle wrapper-stack execution. The DRYRUN wrapper short-circuits the inner adapter execute(); every other layer (bind-point eval, wrapper pulls, metric timing) runs faithfully. The auto-bump in the runner lifts Op to Cycle so the cycle loop actually dispatches.

Cycle

Run cycles with dry-run adapter.

Full

Normal execution.
