CRI-CORE

CRI-CORE v0.7.0 --- Deterministic Enforcement Kernel

CRI-CORE is a deterministic structural enforcement engine for governed state transitions.

It evaluates a run directory against explicit structural, authority, integrity, binding, seal, and publication constraints.

The kernel does not interpret meaning.

It evaluates structure and invariants only.

---

Installation

Install from PyPI:

pip install cricore

Requires Python 3.10+.

---

Minimal Usage

The supported public entrypoint is:

from cricore.enforcement.execution import run_enforcement_pipeline

Example:

from cricore.enforcement.execution import run_enforcement_pipeline

results, commit_allowed = run_enforcement_pipeline(
    run_path=".",
    expected_contract_version="0.3.0"
)

The function returns:

(results: List[StageResult], commit_allowed: bool)

commit_allowed is the sole commit authorization signal.

---

Runtime Input Contracts

CRI-CORE evaluates deterministic run artifacts and explicit mutationrequests.

The kernel relies on two structured input contracts:

• Run artifact contract (run directory structure)
• Mutation proposal object (canonical proposal envelope)

Proposal objects are validated against the canonical proposal schema before enforcement.

Compiled governance contracts may be used by external systems to construct proposal objects, but CRI-CORE does not interpret governance policy directly.

---

Core Model

Exploration (high velocity, non-deterministic)
    →
Deterministic structural gate (CRI-CORE)
    →
Governed state mutation

The kernel ensures that only structurally valid and cryptographically sealed runs are permitted to mutate governed state.

---

Enforcement Pipeline (v0.7.0)

Canonical stage order:

1. run-structure
2. structure-contract-version-gate
3. independence
4. integrity
5. integrity-finalization
6. publication
7. publication-commit

The pipeline is deterministic and ordered.

---

Contract-Version Behavior

CRI-CORE enforces versioned structural guarantees:

For contract_version < 0.3.0:

• Structural validation - Independence enforcement
• Integrity manifest verification

For contract_version ≥ 0.3.0:

• binding.json required
• SEAL.json required
• Strict cryptographic seal validation
• Immutable artifact boundary enforcement

Enforcement meaning is isolated per declared contract version.
Historical runs are validated under their declared version.

---

Independence Model

The kernel enforces structural role separation:

• Explicit actor identities
• Optional declared role requirements (required_roles)
• Strict prohibition on multi-role identity when roles are required
• Explicit override pathway (recorded, never implicit)

The kernel evaluates identity structure only.
It does not evaluate competence or review quality.

---

Cryptographic Guarantees

Finalized runs must include:

• Deterministic SHA256 manifest
• Payload archive
• Structural binding artifact
• Deterministic SEAL.json

The seal covers:

• All run files (deterministic ordering)
• Binding artifact
• Manifest hash
• Payload hash

Any mutation changes the seal hash.

The seal provides tamper evidence.
It is not a signature.

---

Atomic Commit Semantics

CRI-CORE does not mutate state.

It emits a deterministic authorization decision:

commit_allowed = publication_commit_stage.passed

The caller decides whether to mutate.

The kernel centralizes the commit decision.
It does not enforce it outside its invocation boundary.

---

What CRI-CORE Does Not Do

CRI-CORE does not:

• Interpret lifecycle semantics
• Judge correctness of domain objects
• Evaluate epistemic sufficiency
• Enforce governance policy meaning
• Perform distributed consensus
• Prevent bypass outside invocation

It is a deterministic structural gate only.

---

Design Principles

• Deterministic evaluation
• No network calls
• No model calls
• No semantic inference
• Opaque reference handling
• Versioned enforcement meaning
• Strict immutability after finalization

---

Intended Use

CRI-CORE is designed to sit beneath:

• Workflow engines
• CI pipelines
• Agent execution runtimes
• Domain governance systems

It provides:

• Structural admissibility validation
• Cryptographic immutability guarantees
• Centralized commit authorization

It is domain-agnostic.

---

Status

v0.7.0 introduces explicit proposal and contract interface schemas, completing the runtime input hardening phase.

CRI-CORE now operates as a deterministic governed mutation runtime with explicit structural input contracts.

The enforcement interface is stable within the 0.x series but may evolve prior to 1.0.
