Support civic-stack rationale artifact and evidence graph queries

[mdheller]

Purpose

HellGraph should provide the graph storage/query/reasoning surface for the Seven-Model Civic Operating Architecture, including RationalGRL intentional models and OQL/OAC artifact provenance.

Upstream semantic anchors:

• Add seven-model civic organizational alignment for ORG/FOAF/vCard ontogenesis#80 — seven-model civic organizational alignment
• Add RationalGRL and open artifact compiler semantics to civic-stack ontology ontogenesis#81 — RationalGRL and OQL/OAC semantics

Related anchors:

• Consume civic-stack ontology as SocioSphere governance object model sociosphere#323 — governance object model
• Define PRM+ public-value scorecards for civic-stack services delivery-excellence#28 — scoring/evidence rollups
• Bind CGRM and OAC artifact admission policies to civic-stack governance policy-fabric#72 — policy decisions
• Emit civic-stack OQL/OAC runtime evidence from AgentPlane agentplane#154 — runtime evidence
• Attach civic-stack risk controls and evidence packs to ProCybernetica ProCybernetica#40 — assurance evidence packs

Scope

HellGraph should be able to store and query:

• Agent / organization / role / post / membership graphs
• Goal / softgoal / task / resource / contribution / decomposition / dependency graphs
• Policy / right / obligation / legal-basis graphs
• Service / dataset / runtime / attestation graphs
• OQL plan / OAC manifest / artifact / compiler / adapter / deployment graphs
• Provenance / evidence / SBOM / signature / OpenLineage / in-toto references
• Environment / site / exposure / externality graphs from Gaia/EnRM

Acceptance criteria

• Add a civic-stack graph query spec.
• Define named graph partitions for ontology, policy, runtime evidence, delivery metrics, Gaia environment facts, and ProCybernetica evidence packs.
• Define competency queries for accountability: who owned service X, under which policy, using which dataset/runtime, with which attestation and score?
• Define competency queries for rationale: which tasks contribute positively or negatively to a softgoal, and which policy/risk defeaters block execution?
• Define competency queries for OQL/OAC: which artifact derives from which OQL plan, compiler, adapter, manifest, deployment, and evidence pack?
• Define validation/query expectations for SHACL failure visibility.
• Add follow-up implementation tasks once Ontogenesis publishes contexts and shapes.

Non-goals

• HellGraph does not own ontology definitions.
• HellGraph does not own runtime execution.
• HellGraph provides queryable graph substrate and reasoning surface.
