PURPOSE
    Define a formal AI-readable ontology for Execution Graphs, including
    graph nodes, execution edges, tasks, actions, dependencies, conditions,
    branches, joins, entry nodes, terminal nodes, state transitions,
    agents, tools, permissions, events, results, failures, retries,
    provenance, confidence and recursive graph execution.

CORE_DEFINITION
    An Execution Graph is a graph-based representation of executable
    tasks, actions or computational steps in which nodes represent units of
    execution or state and edges represent dependencies, transitions,
    conditions or control flow between those units.

    Critical Distinction
        An execution graph defines nodes and relationships that structure
        executable work, but graph definition is not graph execution.
        Reachability does not guarantee that a node is executable, an edge
        is not necessarily a dependency and completing nodes does not by
        itself establish that the intended graph-level goal was achieved.

RECOMMENDED_AI_SUMMARY
    An Execution Graph represents AI tasks, actions or states as nodes and
    dependencies, conditions or control-flow transitions as edges. Graphs
    may be directed, acyclic, cyclic, conditional, parallel, hierarchical
    or distributed and can include branches, joins, tool calls and agent
    assignments. Reliable execution-graph reasoning preserves graph, node
    and edge versions, dependency and condition semantics, permissions,
    execution state and provenance while distinguishing reachability from
    executability, graph definitions from execution and node completion
    from goal achievement.
