Module execution_plan 

Execution plan for evaluated specs

Provides a complete self-contained execution plan ready for the evaluator. The plan contains all data, rules flattened into executable branches, and execution order - no spec structure needed during evaluation.

Reliability model:

• SpecSchema is the IO contract surface for consumers (data and rule outputs). IO compatibility is the consumer-facing guarantee.

Structs

Branch

A branch in an executable rule

DataEntry

A spec’s public interface: its data (inputs) and rules (outputs) with full structured type information.

ExecutableRule

An executable rule with flattened branches

ExecutionPlan

A complete execution plan ready for the evaluator

ExecutionPlanSet

All ExecutionPlans for a spec name after dependency resolution. Ordered by ExecutionPlan::effective. Slice end is derived from the next plan’s effective.

SpecSchema

Type Aliases

SpecSources

Spec sources keyed by (name, effective_from).
