Status: Draft 1.0 — Forward-looking specification and gap analysis.
This document is not a reverse-engineering report and is not a claim that the reference implementation already satisfies every requirement. It defines the target architecture for a production-grade, provider-neutral Semantic Execution System (SES), identifies the capabilities that remain to be specified or developed, and gives concrete acceptance criteria for future implementations.
The reference implementation may be used as an informative experiment, but the standard is the authority. Where the implementation and this specification differ, the implementation is considered incomplete until it is brought into conformance or the standard is deliberately amended.
Normative terms MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, and MAY have their usual standards meaning.
The Semantic Operation Graph (SOG) is the canonical representation of the complete operation before physical execution. It MUST be sufficient to reason about semantics, authorization, resource cost, and traversal topology without consulting provider-specific code.
The SOG MUST represent, as applicable:
The graph needs a formal treatment of correlation, grouping, windowing, recursive traversal, subqueries, existential predicates, temporal joins, and result shaping. Without these, “whole operation” is too narrow for serious analytical and agentic workloads.
The graph also needs explicit node identity and edge identity semantics so graph hashing cannot accidentally treat distinct security-relevant structures as equivalent.
Define canonical serialization, graph equivalence, graph hashing, graph diffing, graph normalization, recursive constructs, correlation scopes, and complexity accounting.
A graph fingerprint MUST change for every security- or meaning-relevant mutation and remain stable across non-semantic serialization differences.
