Struct PlannedStep 

pub struct PlannedStep {
    pub root_kind: Option<RootKind>,
    pub focus: Option<ExecutionFocus>,
    pub observations: Vec<KernelObservation>,
    pub disposition: StepDisposition,
}

One planned transition, as the canonical driver produces it.

The record freezes only this value’s digest (§22.12), so its shape is what a rebuild has to reproduce bit-for-bit. Three fields, each load-bearing:

• root_kind — the operation’s immutable root class after this step. Present from the root start onward and never different from the value the start committed;
• focus — the execution focus after this step. Because it is inside the digest, a focus that moved differently on a replay is a RecordCorrupted rebuild failure rather than a silent divergence;
• observations — facts produced by this exact transition, published only after commit;
• disposition — effects or a terminal, never both (§7.12).

Fields

root_kind: Option<RootKind>

focus: Option<ExecutionFocus>

observations: Vec<KernelObservation>

disposition: StepDisposition
