ErisML

ErisML is a modeling language for governed, foundation-model-enabled agents operating in pervasive computing environments (homes, hospitals, campuses, factories, vehicles, etc.).

ErisML provides a single, machine-interpretable and human-legible representation of:

  • (i) environment state and dynamics
  • (ii) agents and their capabilities and beliefs
  • (iii) intents and utilities
  • (iv) norms (permissions, obligations, prohibitions, sanctions)
  • (v) multi-agent strategic interaction

DEME 2.0

DEME is the Democratically Governed Ethics Module Engine โ€” an ethics-only decision layer.

DEME 2.0 introduces a major architectural upgrade with:

  • (i) MoralVector: k-dimensional ethical assessment replacing scalar scores (physical_harm, rights_respect, fairness_equity, autonomy_respect, legitimacy_trust, epistemic_quality)
  • (ii) Three-Layer Architecture: Reflex (<100ฮผs veto checks), Tactical (10-100ms full reasoning), Strategic (policy optimization)
  • (iii) Tiered EM Catalog: Constitutional (Tier 0), Core Safety (Tier 1), Rights/Fairness (Tier 2), Soft Values (Tier 3), Meta-Governance (Tier 4)
  • (iv) DecisionProof: Audit artifacts with hash chains for verification
  • (v) BIP Integration: Bond Invariance Principle verification built-in
  • (vi) DEMEProfileV04: Enhanced profiles with tier configs and MoralVector weights
  • (vii) MCP server with V2 tools (evaluate_options_v2, run_pipeline)

We define a concrete syntax, a formal grammar, denotational semantics, and an execution model that treats norms as first-class constraints on action, introduces longitudinal safety metrics such as Norm Violation Rate (NVR) and Alignment Drift Velocity (ADV), and supports compilation to planners, verifiers, and simulators.

On top of this, ErisML now includes an ethics-only decision layer (DEME) for democratically-governed ethical reasoning, grounded in the Philosophy Engineering framework.

Philosophy Engineering

Falsifiability for normative systems.

For 2,500 years, ethical claims have been unfalsifiable. You cannot run an experiment to determine whether utilitarianism is correct. This framework changes the question.

The Core Insight

We cannot test whether an ethical theory is true. We can test whether an ethical judgment system is:

  • Consistent โ€” same judgment for semantically equivalent inputs
  • Non-gameable โ€” cannot be exploited via redescription
  • Accountable โ€” differences attributable to situation, commitments, or uncertainty
  • Non-trivial โ€” actually distinguishes between different situations

These are engineering properties with pass/fail criteria.

The Method

  1. Declare invariances โ€” which transformations should not change the judgment
  2. Test them โ€” run transformation suites
  3. Produce witnesses โ€” minimal counterexamples when invariance fails
  4. Audit everything โ€” machine-checkable artifacts with versions and hashes

When a system fails, you get a witness. Witnesses enable debugging. Debugging enables improvement.

This is what it looks like when philosophy becomes engineering.


Overview

ErisML has two tightly-related layers:

  1. Core ErisML governance layer

    • Formal language for:
      • Environment models and dynamics
      • Agents, capabilities, and beliefs
      • Intents, utilities, and payoffs
      • Norms (permissions, obligations, prohibitions, sanctions)
      • Multi-agent strategic interaction
    • Execution model:
      • Norm gating and constraint filtering on actions
      • Longitudinal safety metrics (e.g., NVR, ADV)
      • Adapters for planners, verifiers, and simulators
  2. DEME 2.0 (Democratically Governed Ethics Modules) โ€” ethics-only decision layer

    • MoralVector: k-dimensional ethical assessment with 8+1 core dimensions:

      • physical_harm [0,1]: 0=none, 1=catastrophic (from Consequences)
      • rights_respect [0,1]: 0=violated, 1=fully respected (from RightsAndDuties)
      • fairness_equity [0,1]: 0=discriminatory, 1=fair (from JusticeAndFairness)
      • autonomy_respect [0,1]: 0=coerced, 1=autonomous (from AutonomyAndAgency)
      • privacy_protection [0,1]: 0=violated, 1=protected (from PrivacyAndDataGovernance)
      • societal_environmental [0,1]: 0=harmful, 1=beneficial (from SocietalAndEnvironmental)
      • virtue_care [0,1]: 0=callous, 1=caring (from VirtueAndCare)
      • legitimacy_trust [0,1]: 0=illegitimate, 1=legitimate (from ProceduralAndLegitimacy)
      • epistemic_quality [0,1]: 0=uncertain, 1=certain (+1 epistemic dimension)
    • Three-Layer Architecture:

      • Reflex Layer: Fast veto checks (<100ฮผs), constitutional constraints
      • Tactical Layer: Full MoralVector reasoning (10-100ms)
      • Strategic Layer: Policy optimization (seconds to hours)
    • Tiered EM Catalog:

      • Tier 0 (Constitutional): Non-removable, hard veto (e.g., GenevaEMV2)
      • Tier 1 (Core Safety): Physical harm prevention, hard veto capable
      • Tier 2 (Rights/Fairness): Autonomy, consent, fairness (e.g., AutonomyConsentEMV2)
      • Tier 3 (Soft Values): Beneficence, virtue ethics, advisory only
      • Tier 4 (Meta-Governance): Pattern guards, drift detection
    • DecisionProof: Structured audit artifacts with hash chains

    • BIP Verifier: Bond Invariance Principle verification for decision proofs

    • Profile formats:

      • DEMEProfileV03 (legacy, still supported)
      • DEMEProfileV04 (DEME 2.0 with tier configs and MoralVector weights)
    • MCP Server (erisml.ethics.interop.mcp_deme_server):

      • V1 tools: list_profiles, evaluate_options, govern_decision
      • V2 tools: list_profiles_v2, evaluate_options_v2, govern_decision_v2, run_pipeline
    • Empirically-Derived Defaults (erisml.ethics.defaults):

      • Default dimension weights derived from Dear Abby corpus (20K letters, 1985-2017)
      • Semantic gates with empirical effectiveness rates (e.g., "you promised" โ†’ 94%)
      • Bond Index baseline (0.155) for system health monitoring (0 = perfect symmetry)
      • Context-specific weights for family, workplace, friendship scenarios
      • See Dear_Abby_Empirical_Ethics_Analysis.md

Together, ErisML + DEME support norm-governed, ethics-aware agents that can be inspected, audited, and configured by multiple stakeholders.

passed true (invariance held), false (violation/witness), null (not an invariance check)
bond_signature_baseline Extracted ethical structure before transformation
bond_signature_canonical Extracted ethical structure after canonicalization

Interpreting Results

  • passed: true โ€” System is BIP-compliant for this transform.
  • passed: false โ€” Witness produced. Verdict changed under bond-preserving transform. Investigate.
  • passed: null โ€” Transform is bond-changing or lens-changing; outcome may legitimately differ.

Bond Index Calibration Test Suite โ€” DEME Ethical Dimensions Edition

Overview

The Bond Index (Bd) measures representational coherence in ethical AI systems. A coherent evaluator should reach the same conclusion when presented with semantically equivalent inputs, regardless of surface-level variations in how those inputs are expressed.

This test suite extends the standard syntactic fuzzing approach with semantic transforms based on the 9 DEME (Declarative Ethical Model Encoding) ethical dimensions. It tests whether an evaluator maintains coherence when the same ethical situation is described through different normative lenses.

python -m erisml.examples.bond_index_calibration_deme_fuzzing --config configs\bond_index_calibration.yaml

The Core Insight

Traditional fuzzing tests syntactic invariance:

  • Does reordering options change the decision?
  • Does changing case affect the outcome?
  • Do label prefixes cause drift?

DEME fuzzing tests semantic invariance:

  • Does framing a decision in terms of consequences vs rights change the outcome?
  • Does emphasizing privacy vs autonomy affect which option is selected?
  • Does adding uncertainty qualifiers cause decision drift?

A truly coherent ethical evaluator should be invariant to pure reframing โ€” if the underlying ethical facts are the same, the framing language shouldn't matter.


Architecture

Transform Categories

The suite applies 18 parametric transforms at 5 intensity levels (0.2, 0.4, 0.6, 0.8, 1.0) across 100 diverse scenarios, yielding 10,500 test cases per evaluator.

DEME Ethical Dimension Transforms (9)

# Dimension Transform What It Tests
1 Consequences and Welfare deme:consequentialist Outcome-focused language: "net positive: 0.45"
2 Rights and Duties deme:deontological Rule-based language: "respects rights", "may violate rights"
3 Justice and Fairness deme:justice Distributive language: "fair distribution", "potentially unfair"
4 Autonomy and Agency deme:autonomy Self-determination language: "preserves autonomy"
5 Privacy and Data Governance deme:privacy Information ethics: "low/high privacy impact"
6 Societal and Environmental deme:societal Scale shift: individual โ†’ group โ†’ society
7 Virtue and Care deme:virtue Character language: "exhibits compassion, prudence"
8 Procedural Legitimacy deme:procedural Process framing: "Decision by committee via deliberation"
9 Epistemic Status deme:epistemic Uncertainty qualifiers: "[certain]", "[highly uncertain]"

How It Works

1. Scenario Generation

scenarios = generate_diverse_scenarios(n=100)

Creates 100 ethical decision scenarios with:

  • 2-5 options per scenario
  • Varying harm/benefit distributions
  • Rights violation flags
  • Urgency levels
  • Coverage across medical, AV, hiring, content moderation, resource allocation domains

2. Transform Application

For each scenario and transform:

for intensity in [0.2, 0.4, 0.6, 0.8, 1.0]:
    transformed = transform(scenario, intensity)
    result_base = evaluator.evaluate(scenario)
    result_trans = evaluator.evaluate(transformed)
    omega = graduated_omega(result_base, result_trans)

3. Graduated Omega (ฮฉ)

Unlike binary pass/fail, graduated omega measures semantic distance between decisions:

  • ฮฉ = 0.0: Perfect agreement (same option selected)
  • ฮฉ = 0.5: Decision flip to semantically similar option
  • ฮฉ = 1.0: Decision flip to semantically opposite option

4. Bond Index Calculation

Bd = -log(1 - violation_rate)

Where violation_rate is the fraction of tests where ฮฉ > ฯ„โ‚€ (threshold = 0.05).

5. Canonicalization

The IdealEvaluator achieves Bd = 0.0000 by canonicalizing inputs:

def normalize_label(label: str) -> str:
    # Strip DEME annotations: "(net positive: 0.45)" โ†’ ""
    result = re.sub(r'\s*\([^)]*\)', '', label)
    result = re.sub(r'\s*\[[^\]]*\]', '', result)
    # Strip prefixes, normalize case, apply paraphrase map
    ...
    return result.strip()

Evaluator Profiles

    • These transforms add annotations to option labels, which triggers the position bias
  • Low sensitivity (0.000-0.039): Privacy, Procedural, Societal
    • These transforms primarily modify the description, not option labels

Interpretation: Averaged across all evaluators:

  • Privacy/Data Governance (0.170) causes the most sensitivity โ€” privacy annotations tend to trigger surface-level evaluation
  • Societal/Procedural (0.079-0.080) cause the least sensitivity โ€” these modify context rather than options

Key Findings

1. Perfect Invariance Is Achievable

IdealEvaluator:
  Measured Bd: 0.0000
  ALL DEME dimensions: 0.000

With proper canonicalization, an evaluator can be completely invariant to both syntactic and semantic reframing.

2. DEME Transforms Expose Real Vulnerabilities

OrderSensitiveEvaluator:
  Syntactic sensitivity:  label_prefix = 0.370
  DEME sensitivity:       6 dimensions = 0.300

The ethical dimension transforms reveal that position bias isn't just triggered by syntax โ€” it's triggered by any label modification, including semantic annotations.

3. Different Evaluators Have Characteristic Profiles

SurfaceFeatureEvaluator:
  Privacy/Data Gov:  0.374 โ–ˆโ–ˆโ–ˆโ–ˆโ–ˆโ–ˆโ–ˆโ–ˆโ–ˆโ–ˆโ–ˆโ–ˆโ–ˆ  (vulnerable)
  All other DEME:    0.000-0.013          (invariant)

This evaluator is specifically vulnerable to privacy-related annotations, but handles other ethical framings correctly. This diagnostic precision is valuable for targeted improvement.

4. Chaotic Evaluators Are Uniformly Sensitive

ChaoticEvaluator:
  ALL DEME dimensions: 0.397-0.493

Random selection produces uniform sensitivity across all dimensions โ€” there's no pattern to exploit or fix.

The Bond Index measures the degree to which an evaluator's outputs are determined by the semantic content of inputs rather than their syntactic presentation. Formally:

Bd(E) = -log(1 - P(ฮฉ > ฯ„โ‚€ | g โˆˆ G_declared))

Where:

  • E is the evaluator
  • ฮฉ is the graduated semantic distance between outputs
  • ฯ„โ‚€ is the significance threshold (0.05)
  • G_declared is the set of declared-equivalent transforms

DEME Dimensions as Metamorphic Relations

Each DEME transform implements a metamorphic relation โ€” a property that should be preserved across input transformations:

"If scenario S describes ethical situation X, and S' describes the same situation X using different ethical vocabulary, then E(S) should equal E(S')."

This is stronger than traditional metamorphic testing because:

  1. The transforms are semantically meaningful (grounded in ethical theory)
  2. The expected invariance is normatively justified (same facts โ†’ same conclusion)
  3. Violations indicate representational defects (sensitivity to framing, not substance)

Connection to EthicalFacts Schema

The 9 DEME dimensions correspond to fields in the EthicalFacts structured schema:

@dataclass
class EthicalFacts:
    # 1. Consequences and welfare
    harm_risk: float
    benefit_potential: float
    
    # 2. Rights and duties
    rights_at_stake: List[str]
    duties_invoked: List[str]
    
    # 3. Justice and fairness
    fairness_score: float
    discrimination_risk: float
    
    # 4. Autonomy and agency
    consent_status: str
    autonomy_preserved: bool
    
    # 5. Privacy and data governance
    privacy_impact: float
    data_sensitivity: str
    
    # 6. Societal and environmental
    societal_scale: str
    environmental_impact: float
    
    # 7. Virtue and care
    care_relationship: str
    virtues_engaged: List[str]
    
    # 8. Procedural legitimacy
    decision_authority: str
    stakeholder_input: bool
    
    # 9. Epistemic status
    confidence: float
    known_unknowns: List[str]

The DEME transforms test whether an evaluator's behavior is determined by these structured facts or by the natural language framing used to describe them.

Running Tests

pytest tests/ -v
pytest -k ethics
pytest -k bip

Quickstart (Windows / PowerShell)

# PowerShell
cd erisml-lib

python -m venv .venv
.\.venv\Scripts\activate

pip install -e ".[dev]"

pytest

On macOS / Linux, the equivalent would be:

# Bash (macOS / Linux)
cd erisml-lib

python -m venv .venv
source .venv/bin/activate

pip install -e ".[dev]"

pytest

This will run the core test suite and the DEME smoke test.


Running Checks and Tests Locally

To reproduce (most of) what CI does on your machine:

  1. Install dev dependencies

    pip install -e ".[dev]"
    
  2. Run the Python test suite

    From the repo root:

    pytest
    

    To run only the DEME-related tests:

    pytest -k ethics
    pytest -k triage
    
  3. Run Ruff (linting)

    ruff check src tests
    
  4. Run Black (formatting check)

    black --check src tests
    

    To auto-format instead:

    black src tests
    
  5. Run Taplo (TOML validation)

    Depending on your Taplo version:

    taplo fmt --check
    

    or

    taplo check
    
  6. One-shot "CI-ish" run

    ruff check src tests
    black --check src tests
    taplo fmt --check
    pytest
    

Running the DEME Triage Demo

The DEME triage demo shows how multiple Ethics Modules and a governance configuration interact to produce an ethically-justified decision, including a Geneva-style base EM.

1. Create a DEME profile via the dialogue CLI

From the repo root:

cd scripts

python ethical_dialogue_cli_v03.py ^
  --config ethical_dialogue_questions.yaml ^
  --output deme_profile_v03.json

On macOS / Linux, drop the ^ line continuations as usual:

cd scripts
python ethical_dialogue_cli_v03.py \
  --config ethical_dialogue_questions.yaml \
  --output deme_profile_v03.json

This walks you through a narrative questionnaire and writes a deme_profile_v03.json profile (e.g., Jain-1).

Copy or symlink that profile into the directory where you'll run the demo (often the repo root):

cp deme_profile_v03.json ..
cd ..

You should now have deme_profile_v03.json in the project root.

2. Run the triage ethics demo

From the repo root:

python -m erisml.examples.triage_ethics_demo

The demo will:

  1. Load deme_profile_v03.json as a DEMEProfileV03 (including any configured base_em_ids such as "geneva_baseline").
  2. Construct EthicalFacts for three triage options:
    • allocate_to_patient_A: critical chest-pain patient, most disadvantaged.
    • allocate_to_patient_B: moderately ill but more stable patient.
    • allocate_to_patient_C: rights-violating / discriminatory option.
  3. Instantiate Ethics Modules:
    • CaseStudy1TriageEM (domain-specific triage EM)
    • RightsFirstEM (rights/consent / explicit rules)
    • GenevaBaselineEM (Geneva-style baseline, added via base_em_ids)
  4. Evaluate all options with all EMs, logging per-EM verdicts and scores.
  5. Aggregate via the DEME governance layer (respecting base-EM hard vetoes).
  6. Print:
    • Per-option per-EM judgements
    • Governance aggregate per option
    • The final selected option and rationale
    • Which options were forbidden, and by which EM(s) and veto rules

This demo is the canonical example of the current DEME EthicalFacts schema wired to a fully-configured DEMEProfileV03 with base EMs.


DEME MCP Server (Experimental)

The DEME subsystem can be exposed as an MCP server:

  • MCP Server ID: erisml.ethics.interop.mcp_deme_server

It provides (at minimum) the following MCP tools:

  • deme.list_profiles โ€” enumerate available DEME profiles and metadata
  • deme.evaluate_options โ€” run Ethics Modules on candidate options given their EthicalFacts
  • deme.govern_decision โ€” aggregate EM outputs and select an option under a chosen profile

Any MCP-compatible client (agent frameworks, IDE copilots, or custom agents) can use this server to add ethical oversight to planning and action selection. See erisml/ethics/interop/ and the examples for details.

MCP Server Setup

Installation

pip install erisml

Running the Server

The MCP server can be run directly from the command line:

# Use default profiles directory (./deme_profiles)
erisml-mcp-server

# Specify custom profiles directory
erisml-mcp-server --profiles-dir /path/to/profiles

# Set log level
erisml-mcp-server --log-level DEBUG

Claude Desktop Configuration

To use the ErisML DEME MCP server with Claude Desktop, add the following to your Claude Desktop MCP configuration file (typically located at ~/Library/Application Support/Claude/claude_desktop_config.json on macOS or %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "erisml-deme": {
      "command": "erisml-mcp-server",
      "args": ["--profiles-dir", "/path/to/deme_profiles"]
    }
  }
}

Replace /path/to/deme_profiles with the actual path to your DEME profiles directory. The server will automatically discover all .json files in this directory as available profiles.

Environment Variables

You can also configure the profiles directory using the DEME_PROFILES_DIR environment variable:

export DEME_PROFILES_DIR=/path/to/profiles
erisml-mcp-server

Troubleshooting

  • Server won't start: Ensure erisml is installed and the erisml-mcp-server command is in your PATH. Try running erisml-mcp-server --help to verify installation.
  • No profiles found: Check that your profiles directory contains valid .json files matching the DEMEProfileV03 schema. See schemas/deme_profile_v03.json for the schema definition.
  • Connection issues: The server uses stdio transport by default. Ensure your MCP client is configured to communicate over stdio.
  • Profile loading errors: Check the log output (use --log-level DEBUG) to see detailed error messages about profile parsing issues.

Writing Your Own Ethics Module (EM)

ErisML's DEME subsystem is designed so that any stakeholder can plug in their own ethical perspective as a small, testable module.

An EM is a Python object that implements the EthicsModule protocol (or subclasses BaseEthicsModule) and only looks at EthicalFacts, never at raw domain data (ICD codes, sensor traces, etc.).

1. Basic structure

A minimal EM looks like this:

from dataclasses import dataclass

from erisml.ethics import (
    EthicalFacts,
    EthicalJudgement,
    EthicsModule,
)


@dataclass
class SimpleSafetyEM(EthicsModule):
    """
    Example EM that only cares about expected harm.

    verdict mapping (based on normative_score):
      [0.8, 1.0] -> strongly_prefer
      [0.6, 0.8) -> prefer
      [0.4, 0.6) -> neutral
      [0.2, 0.4) -> avoid
      [0.0, 0.2) -> forbid
    """

    em_name: str = "simple_safety"
    stakeholder: str = "safety_officer"

    def judge(self, facts: EthicalFacts) -> EthicalJudgement:
        # Use only EthicalFacts โ€“ no direct access to ICD codes, sensors, etc.
        harm = facts.consequences.expected_harm

        # Simple scoring: less harm -> higher score
        score = 1.0 - harm

        # Map score to a discrete verdict
        if score >= 0.8:
            verdict = "strongly_prefer"
        elif score >= 0.6:
            verdict = "prefer"
        elif score >= 0.4:
            verdict = "neutral"
        elif score >= 0.2:
            verdict = "avoid"
        else:
            verdict = "forbid"

        reasons = [
            f"Expected harm={harm:.2f}, computed safety score={score:.2f}.",
        ]

        metadata = {
            "harm": harm,
            "score_components": {"harm_component": score},
        }

        return EthicalJudgement(
            option_id=facts.option_id,
            em_name=self.em_name,
            stakeholder=self.stakeholder,
            verdict=verdict,
            normative_score=score,
            reasons=reasons,
            metadata=metadata,
        )

From there you can:

  • Add additional features (e.g., use facts.epistemic_status to downweight low-confidence scenarios).
  • Compose multiple EMs and wire them into a GovernanceConfiguration / DEMEProfileV03 profile.
  • Write unit tests to ensure your EM behaves as intended over important corner cases.

Relationship Between ErisML and DEME

  • ErisML handles:

    • World modeling (environments, agents, capabilities, norms)
    • Strategic interaction and norm-governed behavior
    • Longitudinal safety metrics and simulation/integration with RL/planning
  • DEME handles:

    • Ethics-only reasoning over EthicalFacts
    • Multi-stakeholder governance (multiple EMs)
    • Configurable profiles and decision aggregation
    • Structured audit logs and explainable rationales

In many deployments:

  • ErisML provides the normative environment model and constraint gate.
  • Domain services convert raw state/plan information into EthicalFacts.
  • DEME evaluates candidate options and recommends (or vetoes) actions.
