CRG Systems v1.5.0

CRG Systems v1.5.0 is the verified public-runtime distribution for the v1.5.0 source checkpoint.

CRG Systems operationalizes Computation-Realization Geometry for realization modeling, decision certification, evidence and qualification workflows, change control, portable verification, and controlled physical feedback.

What’s new

• Caps the cumulative CRG 1.x commitment stack with an agent-native boundary for AI-native chip design. Exact realization identity, governed retention, challengeable change, qualified evidence, continued validity, and authority separation now compose into durable Realization Memory for the alternatives, evidence, decisions, and reopening conditions behind consequential reductions.
• Adds deterministic design-space reduction for the crg-agent-design-space/compiler-operator-dag@1 profile. From a closed operator DAG, CRG derives finite generator closure, the legal realization family, exact R / Gamma / K geometry, decision queries, and retention policies, then returns exact retained and pruned realization records with portable certificates, constructive regret witnesses, or typed refusals.
• Makes completeness and resource boundaries machine-checkable. Callers cannot submit the derived family, geometry, or commitment result as facts or assert that generation is complete; exact numeric input and explicit limits govern the request; truncation remains PARTIAL_FAMILY; and overflow or no-legal-realization cases refuse before an unsupported commitment is constructed.
• Carries the same operation across the CLI, durable and idempotent REST jobs, generated Python and JavaScript clients, and the Embedded Developer Kit. Semantic result hashes remain distinct from storage content addresses, while the code-separated verifier reconstructs the graph, generation, exact geometry, safe commitment, and reduced spaces instead of trusting a producer success flag.
• Adds a causal Agent Event ABI and assess→commit→ack receipts, together with grants, proposals, conflicts, and revocation for bounded multi-agent coordination. These capabilities expose an auditable coordination boundary while preserving the rule that assessment is not execution authority.
• Adds canonical package resolution and restricted execution contracts while keeping assessment separate from execution authority. CRG remains a bounded commitment and verification layer alongside compilers, optimizers, EDA tools, simulators, and organizational policy; it does not replace those systems or inherit their authority.
• Integrates the capstone through 17 component packages, 36 top-level CLI commands, 103 API paths with 106 operations, 17 Studio workspaces, 100 public schemas, seven first-party packs, and generated Python and JavaScript clients, backed by versioned schemas, content-addressed records, durable jobs, idempotent interfaces, and migrations.
• Ships with seven reference packs that regenerate bit-identically; the v1.5 reference passes 47 of 47 mandatory compatibility cases across 13 profiles, and the separately implemented Node verifier passes its 10 applicable cases. These are executable reference and conformance results, not field qualification.

Compatibility

This is an additive 1.x release. AgentDesignSpaceRequest and AgentDesignSpaceResult introduce versioned v1.5 records for the registered compiler-operator-DAG profile; older readers may refuse new record types, and unknown, unsupported, incomplete, or resource-truncated semantics fail closed rather than being promoted. Every prior supported 1.x artifact retains its declared version and verification path. Assessment results, pruning certificates, transport receipts, and multi-agent coordination records do not confer execution, publication, tape-out, or repository-mutation authority; deployment-owned policy remains the authority boundary.
