anchor-audit 5.0.4

The Federated Governance Engine for AI (Universal Multi-Language)

ANCHOR (v5.0.2)

The Cryptographic Enforcement Kernel for Agentic AI

"Probabilistic observation is not governance. Mathematical enforcement is."

Anchor is a federated, two-layer governance engine designed to mathematically seal the behavior of autonomous AI systems. It replaces post-hoc probabilistic classifiers with deterministic structural contracts, ensuring zero "intent drift" in high-frequency, high-stakes financial and operational routing.

This is not a linter. This is the Decision Audit Chain (DAC).

---

I. The Mandate: Zero Intent Drift

As AI models are granted autonomous tool-calling capabilities, the divergence between initial semantic intent ($v_i$) and executed state ($v_e$) creates catastrophic liability. Drift ($D$) is defined as:

$$D = \int_{0}^{t} \mathcal{L}(v_i, v_e) , dt$$

Anchor is architected to guarantee $D < \epsilon$ through cryptographic enforcement. If an autonomous agent cannot mathematically prove its adherence to the sealed operational constitution, execution is blocked at the kernel level.

Why Anchor Exists

Event	Date	Amount
Goldman Sachs CFPB enforcement — AI explainability failure	Oct 2024	$45M
EU AI Act full enforcement begins — credit scoring, AML, fraud	Aug 2026	Mandatory
SEC AI Governance — named #1 examination priority, above crypto	2026	Mandatory
RBI FREE-AI — 26 mandatory recommendations, per-decision audit trails	Aug 2025	Mandatory

II. Main Anchor Architecture

Anchor operates across the complete lifecycle of the intelligence, unified by a single, SHA-256 sealed constitution.anchor.

The Data Flow (Numbered)

1. Local Audit: DecisionAuditor.audit() writes every decision to .anchor/runtime_chain.jsonl with HMAC-SHA256 chain linking
2. Spoke Ingress: If ANCHOR_LEDGER_URL is set, the full payload is HTTP POST'd to the enterprise's local Spoke node
3. Hub Header: Spoke pushes a lightweight AUDIT_HEADER (~200 bytes) over persistent WebSocket — no raw data crosses the perimeter
4. Enterprise Dashboard: Enterprise users see their audit chain, fleet status, and compliance scores via REST API
5. Oversight Dashboard: Regulators see aggregated compliance metadata and can request forensic details
6. Mesh Visualization: The 3D Terminal Mesh globe shows active nodes and relay status
7. Forensic Pull: When a regulator needs the raw payload, they trigger a FORENSIC_PULL through the Hub
8. Encrypted Relay: Hub relays the request to the Spoke, which encrypts the payload with AES-256-GCM and sends it back

III. The Federated Model

Anchor operates on a three-layer constitutional architecture:

Layer	File	Purpose
Constitution	constitution.anchor	Defines WHAT risks exist. Domain + framework + regulator manifest. SHA-256 sealed via remote GOVERNANCE.lock.
Mitigation Catalog	mitigation.anchor	Defines HOW to detect each risk. Regex + AST patterns. Cloud-synced.
State Law	policy.anchor	Your local overrides. Change severity, add company-specific rules.

Coverage — V5.0.2

Tier	Content	Count
Domain Rules	SEC, ETH, PRV, ALN, AGT, LEG, OPS, SUP, SHR	43 rules
Standards Bodies	FINOS AI Governance, OWASP LLM Top 10 · 2025, NIST AI RMF 1.0	3 frameworks
Government Regulators	RBI FREE-AI 2025, EU AI Act 2024/1689, SEBI AI/ML 2025, CFPB Reg B, FCA 2024, SEC 2026	6 regulators
Total Regulatory Mappings		170+ mappings

---

IV. Key Design Principles

Principle	Implementation
Constitutional Floor	constitution.anchor defines immutable severity baselines. policy.anchor can only RAISE, never lower.
Federated Identity	Each rule has a canonical ID (e.g. SEC-007) that maps through alias chains to FINOS, OWASP, and regulator rules
Data Sovereignty	Raw forensic data stays on the enterprise's Spoke node. Only cryptographic metadata flows to the Hub.
Audit-Not-Block	The @enforce decorator records violations without interrupting the application. Block mode is opt-in.
Surgical Containment	AnchorViolationError blocks the specific payload but keeps the application session alive.
Zero-Knowledge Proof	Regulators verify compliance via chain_hash + signature without needing access to raw prompts/responses.
Multi-Dialect Export	One AuditEntry can be exported as RBI (Sutras), SEC (8-K), or EU AI Act (Article 12) format.

---

V. v5.0.2: The Primitive Vocabulary

Version 5 introduces the algorithmic decomposition of regulatory risk. Governance is no longer reliant on vague, hand-authored regex. Every regulatory statute (EU AI Act, FINOS, CFPB, SEC) is algorithmically compiled into five primitive enforcement nodes:

• [ACTION] - The operational vector.
• [OBJECT] - The target entity.
• [CONTEXT] - The environmental state.
• [AUTHORITY] - The cryptographic signature requirement.
• [FLOW] - The data trajectory.

---

VI. The Anchor Healer: Autonomous Remediation

Beyond detection, Anchor v5.0.2 introduces the Healer node. When a violation is detected in the AST or runtime stream, Anchor generates a mathematically verified patch (MVP) that restricts the execution path without breaking functionality. This patch is then validated inside the Diamond Cage before deployment.

---

VII. Cryptographic Integrity (GOVERNANCE.lock)

Anchor enforces a strict "Governance Floor Invariant."

The GOVERNANCE.lock mechanism seals all 18 active policy and domain files (SEC, ETH, PRV, ALN, AGT) via SHA-256. Any local modification to the ruleset by an unauthorized developer produces an immediate hash mismatch and deployment failure.

You cannot silently weaken the law.

IX. CI/CD Integration

Anchor acts as the enforcement gate in GitHub Actions. If a PR violates the constitution, Anchor blocks the merge with a detailed violation report.

# .github/workflows/anchor-audit.yml
- name: Run Governance Check
  run: |
    pip install anchor-audit
    anchor check --dir ./src --severity error --json-report --github-summary

---

X. Suppressing Findings

When a finding is a justified use (e.g., your governance tool legitimately needs subprocess), suppress it with an inline comment:

# Per-rule suppression
result = subprocess.run(cmd, capture_output=True)  # anchor: ignore ANC-018

# Suppress all rules on a line
os.environ.get("SECRET_KEY")  # anchor: ignore-all

Feature	Details
Scope	Line-level only
Audit Trail	Anchor uses git blame to record who authorized each suppression
Visibility	Suppressed findings appear in the report with the author's name
