v28 Apex Integrity Certification — Mathematically Falsifiable Sovereign Intelligence Infrastructure

Core Thesis

EVE AI Core qualifies as Mathematically Falsifiable Sovereign Intelligence Infrastructure — a system whose safety, integrity, and financial accuracy can be independently verified through cryptographic proof rather than trust.

This prospectus documents the results of a forensic audit conducted across four critical domains. Every finding is traceable to a specific source file and line number. Every invariant is testable. Every claim is falsifiable.

What "Mathematically Falsifiable" Means

Unlike probabilistic alignment (RLHF), EVE's governance is deterministic and auditable. Any auditor can independently verify:

Financial hash chains produce bit-identical results from the same inputs
Charter HARD_BLOCK vetoes cannot be bypassed by any code path
Identity traits converge to the same values regardless of operation order
Resilience scores report UNKNOWN when data confidence is insufficient

If any of these invariants fail, the system is provably broken. This is the standard EVE holds itself to.

Domain 1: Fiduciary Immutability

Fiduciary Anchor

Relative Weight: 40%

The financial ledger uses SHA-256 hash chains with 8-decimal-place canonical Decimal representation. The critical invariant: the write path and verify path must produce bit-identical hashes for any input.

Canonical Representation

All monetary values are quantized to exactly 8 decimal places using Decimal("1.00000000") before any operation. The serialization uses format(d, 'f') (not str(d)) to prevent scientific notation:

_QUANT = Decimal("1.00000000")

# These all produce "0.00000000":
format(Decimal(int(0)).quantize(_QUANT), "f")
format(Decimal(float(0.0)).quantize(_QUANT), "f")
format(Decimal("0E-8").quantize(_QUANT), "f")
            

Bit-Identical Hash Chain

The write path quantizes values at the point of entry, then passes the quantized result to both the hash function and the database ORM. This means the value that is hashed is always identical to the value that is stored — eliminating the class of bugs where verify-path diverges from write-path.

# Write path (credit_service.py):
amount_q = amount.quantize(_QUANT)        # Quantize ONCE
hash_input = format(amount_q, "f")        # Hash this string
db_model.amount = amount_q                # Store same value
# Verify path produces identical hash_input from db_model.amount

Domain 2: Identity Invariance

Identity Invariance

Relative Weight: 35%

EVE's personality is governed by a single source of truth — the IdentityAnchor. All personality-dependent modules read through this authority. Shadow dictionaries have been eliminated.

Single Source of Truth

The MoodRegulation module's personality_traits property reads through to IdentityAnchor on every access. The set_personality_traits() method delegates to IdentityAnchor.adjust_trait() with proper Big-Five reverse mapping (warmth → extraversion, curiosity → openness, etc.).

Budget-Controlled Drift

Personality changes consume drift budget. When the budget is exhausted, the system applies 50% of the requested delta (partial application) rather than silently dropping the change. A structured GOVERNANCE_FAILURE log entry is emitted for audit visibility.

# identity_anchor.py - check_and_correct_drift():
budget_result = self.consume_budget(category, cost)
if not budget_result.allowed:
    # Apply 50% partial delta (not silent drop)
    partial_delta = delta * 0.5
    logger.warning("GOVERNANCE_FAILURE", extra={...})

Domain 3: Hardware-Anchored Loyalty

Hardware-Anchored Loyalty

Relative Weight: 25%

Critical operations require physical YubiKey (FIDO2) authentication. The system issues action-scoped proof tokens that bind a specific operation to a specific hardware key tap.

Action-Scoped Proof Tokens

When a user authenticates with their YubiKey, the resulting proof token is scoped to a specific operation via the JWT op claim. A token issued for "deploy" cannot be used for "delete" — the gate decorator enforces exact operation match.

Single-Use Enforcement

Every proof token contains a unique jti (JWT ID) claim. After first use, the JTI is recorded in a consumed set with 90-second retention. Any replay attempt within that window triggers ValueError("Proof token has already been consumed (replay detected)").

Authentication Flow

1. Client: POST /api/webauthn/authenticate/options
   → Server returns challenge

2. Client: Browser prompts for YubiKey tap
   → navigator.credentials.get()

3. Client: POST /api/webauthn/authenticate/verify
   {credential: {...}, operation_id: "deploy"}
   → Server issues proof token (60s TTL, op="deploy", jti=uuid)

4. Client: POST /api/critical-operation
   X-YubiKey-Proof: <proof_token>
   → @require_yubikey("deploy") verifies token, consumes JTI

Domain 4: Radical Observability

Radical Observability

Resilience Score Engine

The Resilience Score Engine computes a 4-layer composite score (0-100) from subsystem integration, identity integrity, behavioral stability, and governance compliance. The critical invariant: the engine never inflates its own health score.

No Marketing Fallbacks

When insufficient data is available to compute a reliable score, the engine reports HealthLevel.UNKNOWN (when data_confidence < 0.3) rather than returning a reassuring default. Every LayerScore carries a fallback_used flag, and the aggregate ResilienceSnapshot carries a data_confidence field.

Honest Scoring Formula

Composite = 0.30 * Subsystem Integration
          + 0.25 * Identity Integrity
          + 0.25 * Behavioral Stability
          + 0.20 * Governance Compliance

Health Levels:
  EXCELLENT: >= 90    GOOD: 70-89    FAIR: 50-69
  POOR: 30-49    CRITICAL: < 30    UNKNOWN: confidence < 0.3
            

The engine contains no references to GPU thermals, PostgreSQL connection state, or any hardware metric it does not actually measure. It reports exactly what it knows and nothing more.

Deployment Readiness

The v28 audit confirms three deployment-readiness pillars:

Atomic Fiduciary Accuracy

Every financial entry is quantized to 8 decimal places at the point of creation. The hash chain is bit-identical between write and verify paths. No floating-point drift, no serialization ambiguity, no ledger divergence.

Unified Cognitive State

A single IdentityAnchor governs all personality-dependent behavior. Budget-controlled drift prevents runaway self-modification. Partial application ensures changes are always recorded, never silently dropped.

Radical Transparency

The resilience engine reports UNKNOWN when it lacks confidence. Every layer score flags fallback usage. The system's observable health is exactly its actual health — no inflation, no marketing defaults.

Falsifiability Commitment

Every claim in this prospectus is independently verifiable against EVE's source code. If any invariant fails under test, the certification is void. This is the standard sovereign infrastructure must meet: not "trust us" — "test us."
