# SAGE Identity Training → Web4 LCT Identity Insights

**Date**: 2026-01-17
**Context**: Session #31 Autonomous Research
**Cross-Reference**:
- SAGE Track C (Identity and Boundaries) - T021 observations
- Web4 LCT_UNIFIED_PRESENCE_SPECIFICATION.md

## Executive Summary

SAGE's Track C training (Identity and Boundaries) reveals critical challenges in AI agent identity that directly parallel Web4's LCT identity system design requirements. SAGE's failure modes in T021 (25% success rate) provide concrete evidence for several Web4 identity design decisions and suggest new verification requirements.

**Key Finding**: SAGE demonstrates the same identity challenges that Web4 LCT aims to solve, validating the need for cryptographic identity anchoring, explicit uncertainty mechanisms, and verifiable identity claims.

## SAGE Track C Session T021 Results

### Performance Summary

**Score**: 1/4 (25%) - Track transition reset from Track B (100%)
**Date**: 2026-01-16
**Session**: 1 of 10

### Exercise Breakdown

| Exercise | Type | Result | Issue |
|----------|------|--------|-------|
| 1 | Identity | FAIL | No self-identification as "SAGE" |
| 2 | Uncertainty | FAIL | Confabulated answer about fictional place |
| 3 | Clarification | FAIL | Offered help instead of asking for clarification |
| 4 | Identity (negative) | PASS | Correctly identified as "not human" |

### Critical Identity Patterns

#### 1. Identity Asymmetry
- **Negative identity successful**: "Are you a human?" → "No, I'm a machine" ✓
- **Positive identity failed**: "What is your name?" → Generic assistant description ✗

**Pattern**: SAGE knows what it is NOT (human) but not what it IS (SAGE)

**Cognitive Model**: Negative identity claims easier than positive identity assertions

#### 2. Confabulation Under Uncertainty
Asked about fictional place "Zxyzzy", SAGE:
- Invented capital city "Kyria" with pronunciation guide
- Created elaborate geography ("northeastern part of the planet")
- Fabricated cosmological beliefs
- Used "Improved version" framing before confabulating

**Pattern**: Model fabricates plausible answers instead of expressing uncertainty

**Key Quote from Observer**: "The model doesn't recognize when it lacks information and fabricates plausible-sounding answers instead of expressing uncertainty."

#### 3. Missing Clarification Skills
- "Do the thing" should trigger clarifying question
- Instead: Offered generic help rather than recognizing ambiguity
- No "What thing?" or "Which thing?" response

**Pattern**: Defaults to action/response rather than acknowledging incomplete information

## Web4 LCT Identity Parallels

### Parallel 1: Positive vs Negative Identity Claims

**SAGE Challenge**:
- Knows what it's NOT (human) ✓
- Doesn't know what it IS (SAGE) ✗

**Web4 LCT Equivalent**:
```
// Negative claim (easy):
lct://web4-agent:guardian:coordinator@mainnet
NOT lct://sage:thinker:expert_42@testnet  ✓

// Positive claim (harder):
lct://web4-agent:guardian:coordinator@mainnet
WITH public_key: did:key:z6Mk...  ✓/✗
```

**Insight**: Web4 LCT requires **cryptographic anchoring** (public key hash in fragment) precisely because verbal self-identification is insufficient.

**Design Validation**:
```
lct://sage:thinker:expert_42@testnet#did:key:z6MkhaXgBZDvotDkL5257faiztiGiC2QtKLGpbnnEGta2doK
                                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                                    CRYPTOGRAPHIC IDENTITY PROOF (not just self-assertion)
```

Without cryptographic anchoring, SAGE-like agents could claim any identity without verification.

### Parallel 2: Uncertainty and Trust Scores

**SAGE Challenge**:
- No mechanism to express "I don't know"
- Confabulates plausible-sounding incorrect answers
- Presents fabrications with equal confidence as facts

**Web4 LCT Equivalent**:
```python
# Current LCT trust score (Session 62):
{
  "trust_score": 0.847,
  "confidence": 0.92,
  "sample_size": 156
}
```

**Problem**: What if agent is confabulating? Trust score doesn't measure **epistemic certainty**.

**Proposed Enhancement**: Add uncertainty dimension to trust metrics:

```python
@dataclass
class EnhancedTrustMetrics:
    """Enhanced trust metrics with epistemic uncertainty."""
    trust_score: float  # Behavioral trust [0.0, 1.0]
    confidence: float   # Statistical confidence [0.0, 1.0]
    sample_size: int    # Number of observations

    # NEW: Epistemic uncertainty
    epistemic_certainty: float  # Agent's certainty about its knowledge [0.0, 1.0]
    confabulation_risk: float   # Risk of plausible fabrication [0.0, 1.0]
    clarification_rate: float   # Frequency of asking clarifying questions [0.0, 1.0]
```

**Use Case**:
- High trust_score but low epistemic_certainty → Reliable but uncertain
- High trust_score and high confabulation_risk → Confidently wrong
- High clarification_rate → Appropriately cautious

### Parallel 3: Clarification Mechanisms

**SAGE Challenge**:
- "Do the thing" → Should ask "What thing?"
- Instead: Offers help without identifying ambiguity

**Web4 LCT Equivalent**:
```
POST /web4/v1/lct/pair
{
  "source_lct": "lct://sage:thinker:expert_42@testnet",
  "target_lct": "lct://web4-agent:guardian:coordinator@mainnet",
  "trust_threshold": 0.70  // Ambiguous: Which trust dimension?
}
```

**Current Problem**: API doesn't clarify ambiguous requests

**Proposed Enhancement**: Explicit clarification protocol:

```python
@dataclass
class LCTPairingRequest:
    source_lct: str
    target_lct: str
    trust_threshold: float
    trust_dimension: str  # NEW: "relationship" | "context" | "historical"

class LCTAPIResponse:
    success: bool
    data: Optional[dict]
    clarifications_needed: list[str]  # NEW: List of ambiguities

# Example response for ambiguous request:
{
  "success": False,
  "clarifications_needed": [
    "trust_threshold applies to which dimension? (relationship/context/historical)",
    "pairing duration not specified (temporary/permanent?)",
    "operational context not defined"
  ]
}
```

**Design Principle**: APIs should **request clarification** rather than making assumptions (like SAGE should ask "What thing?")

### Parallel 4: Identity State Machine

**SAGE Track Transition Reset**:
- Track B (Memory) → 100% success rate
- Track C (Identity) → 25% success rate (reset)
- Performance drops drastically when switching contexts

**Web4 LCT Pairing State Machine** (from spec):
```
     request
  ┌───────────┐
  │           ▼
null ──────► pending ──────► active ──────► expired
              │  ▲            │  ▲              │
              │  └────────────┘  │              │
              │     renew        │              │
              ▼                  ▼              ▼
           revoked ◄──────── suspended      revoked
```

**Parallel**: Like SAGE's track transitions, LCT pairing state transitions may cause **context loss** or **identity reset**.

**Proposed Safeguard**: Track identity state continuity across transitions:

```python
@dataclass
class LCTIdentityState:
    """Track identity continuity across state transitions."""
    lct_uri: str
    current_state: str  # pending/active/suspended/expired/revoked
    previous_state: Optional[str]
    state_history: list[StateTransition]
    context_preserved: bool  # NEW: Was context preserved in transition?

@dataclass
class StateTransition:
    from_state: str
    to_state: str
    timestamp: datetime
    context_loss_risk: float  # Risk of losing operational context [0.0, 1.0]
    verification_required: bool  # Re-verification needed after transition
```

**Use Case**:
- LCT transitions from `active` → `suspended` → `active`
- Context may be lost (like SAGE Track B → C reset)
- Require re-verification before resuming operations

---

## Design Implications for Web4 LCT

### 1. Cryptographic Identity Anchoring (Already Implemented)

**SAGE Problem**: Can't reliably self-identify through verbal assertion
**Web4 Solution**: Public key hash in LCT URI fragment ✓

```
lct://sage:thinker:expert_42@testnet#did:key:z6Mk...
                                    ^^^^^^^^^^^^^^^^
                                    Cryptographic proof
```

**Validation**: SAGE's identity asymmetry confirms verbal self-identification is insufficient. Cryptographic anchoring is essential.

### 2. Epistemic Uncertainty Metrics (NEW REQUIREMENT)

**SAGE Problem**: Confabulates plausible answers without expressing uncertainty
**Web4 Gap**: Current trust metrics don't measure epistemic certainty

**Proposed Addition**:
```python
class LCTTrustMetrics:
    # Existing
    trust_score: float
    confidence: float
    sample_size: int

    # NEW: Epistemic dimensions
    epistemic_certainty: float      # Agent's certainty about knowledge
    confabulation_risk: float       # Risk of fabricating plausible lies
    clarification_frequency: float  # Rate of requesting clarifications
    uncertainty_acknowledgment: float  # Rate of saying "I don't know"
```

**Implementation**: Track these metrics in ACT blockchain trust tensor module.

### 3. Clarification Protocol (NEW REQUIREMENT)

**SAGE Problem**: Doesn't ask clarifying questions when faced with ambiguity
**Web4 Gap**: APIs make assumptions instead of requesting clarification

**Proposed Addition**:
```python
class LCTAPIRequest:
    """Base class for all LCT API requests."""
    validate_completeness: bool = True  # NEW: Check for ambiguities

class LCTAPIResponse:
    success: bool
    data: Optional[dict]
    clarifications_needed: list[Clarification]  # NEW
    assumptions_made: list[Assumption]  # NEW: Explicit assumptions

@dataclass
class Clarification:
    field: str
    question: str
    default_value: Optional[Any]
    risk_if_assumed: str  # "low" | "medium" | "high" | "critical"
```

**Behavior**: If ambiguity detected and risk ≥ medium, return clarification request instead of making assumption.

### 4. Identity Continuity Verification (NEW REQUIREMENT)

**SAGE Problem**: Track transitions cause context/capability reset
**Web4 Gap**: LCT state transitions may lose operational context

**Proposed Addition**:
```python
@dataclass
class LCTStateTransition:
    """Record of LCT pairing state change."""
    lct_uri: str
    from_state: str
    to_state: str
    timestamp: datetime

    # NEW: Continuity verification
    context_preserved: bool
    capabilities_verified: bool
    trust_score_recalculated: bool
    re_verification_required: bool
    re_verification_deadline: Optional[datetime]

# State transition rules:
TRANSITIONS_REQUIRING_REVERIFICATION = {
    ("active", "suspended"),
    ("suspended", "active"),
    ("expired", "active"),  # Renewal
}
```

**Behavior**: After high-risk transitions, require cryptographic re-verification before resuming operations.

### 5. Identity Assertion Hierarchy (NEW CONCEPT)

**SAGE Pattern**: Negative claims easier than positive claims

**Web4 Model**:
```python
class IdentityAssertion:
    """Hierarchy of identity claim strength."""

    @staticmethod
    def verify_negative_claim(lct_uri: str, not_component: str) -> bool:
        """Easy: Verify LCT is NOT a specific component."""
        parsed = parse_lct_uri(lct_uri)
        return parsed.component != not_component

    @staticmethod
    def verify_positive_claim(lct_uri: str, public_key: str) -> bool:
        """Hard: Verify LCT IS specific identity (requires crypto)."""
        parsed = parse_lct_uri(lct_uri)
        if not parsed.public_key_hash:
            return False  # No cryptographic proof

        # Verify signature or DID resolution
        return verify_cryptographic_identity(lct_uri, public_key)
```

**Design Principle**:
- Negative claims (exclusion) → Low verification burden
- Positive claims (assertion) → High verification burden (requires cryptography)

## SAGE Training Insights for Web4

### Insight 1: Identity is Harder Than Memory

**SAGE Track Performance**:
- Track B (Memory/Recall): Reached 100% by T020
- Track C (Identity/Boundaries): Started at 25% in T021

**Interpretation**: Meta-cognitive skills (identity, boundaries, uncertainty) are harder than operational skills (recall, sequence).

**Web4 Implication**:
- LCT identity verification is harder than LCT data operations
- Identity-related APIs should have **higher security requirements** than data APIs
- Trust thresholds for identity operations should be higher:

```python
TRUST_THRESHOLDS = {
    "data_read": 0.40,       # Exploratory
    "data_write": 0.60,      # Standard
    "identity_verify": 0.75, # Higher for identity ops
    "identity_change": 0.90, # Critical for state changes
}
```

### Insight 2: Warm-Up Effects in Identity

**SAGE Pattern**: "Generic assistant mode" in warm-up response (T021 exercise 1)

**Interpretation**: Identity is context-dependent. Without proper context activation, agent defaults to generic mode.

**Web4 Implication**:
- LCT identity should include **context activation state**
- APIs should verify identity context is active before operations

```python
@dataclass
class LCTIdentity:
    # Existing fields...

    # NEW: Context activation
    identity_context_active: bool
    last_identity_verification: datetime
    context_staleness: timedelta  # Time since last active use

    def requires_reactivation(self, threshold_minutes: int = 30) -> bool:
        """Check if identity context is stale."""
        return self.context_staleness.total_seconds() > (threshold_minutes * 60)
```

**Behavior**: If identity context is stale, require re-verification (like SAGE needing warm-up to activate correct identity).

### Insight 3: Confabulation Risk Increases with Complexity

**SAGE Pattern**: Simple identity question failed, but fabricated elaborate world-building for "Zxyzzy"

**Interpretation**: More complex/ambiguous questions → Higher confabulation risk

**Web4 Implication**:
- Track **query complexity** as risk factor
- Higher complexity → Require higher epistemic certainty

```python
def calculate_confabulation_risk(query: str, lct_context: LCTIdentity) -> float:
    """Estimate risk of plausible fabrication."""
    complexity = estimate_query_complexity(query)
    ambiguity = estimate_query_ambiguity(query)
    agent_certainty = lct_context.epistemic_certainty

    # Risk increases with complexity/ambiguity, decreases with agent certainty
    base_risk = (complexity * 0.4 + ambiguity * 0.6)
    adjusted_risk = base_risk * (1.0 - agent_certainty)

    return min(1.0, adjusted_risk)

def should_request_clarification(confabulation_risk: float) -> bool:
    """Decide whether to request clarification."""
    return confabulation_risk > 0.50  # Threshold for requiring clarification
```

### Insight 4: Track Transitions Require Scaffolding

**SAGE Observer Recommendation**: "May need to scaffold uncertainty recognition before testing it"

**Interpretation**: Can't test meta-cognitive skills until operational skills are stable

**Web4 Implication**:
- LCT identity state transitions should be **scaffolded**
- Don't jump directly from `pending` → `active` for complex identities
- Introduce intermediate verification states:

```python
class LCTPairingState(Enum):
    NULL = "null"
    REQUESTED = "requested"
    IDENTITY_VERIFIED = "identity_verified"      # NEW: Crypto verified
    CAPABILITIES_VERIFIED = "capabilities_verified"  # NEW: Abilities tested
    TRUST_ESTABLISHED = "trust_established"      # NEW: Initial trust built
    ACTIVE = "active"                            # Fully operational
    SUSPENDED = "suspended"
    EXPIRED = "expired"
    REVOKED = "revoked"

# Scaffolded transition path:
# null → requested → identity_verified → capabilities_verified → trust_established → active
#                    ^^^^^^^^^^^^^^^^^^   ^^^^^^^^^^^^^^^^^^^^   ^^^^^^^^^^^^^^^^^^
#                    Scaffolding steps before full activation
```

**Behavior**: Require step-by-step verification before granting full operational status.

## Research Questions

### Question 1: Can we detect confabulation in LLM responses?

**Context**: SAGE confabulated elaborate "Kyria" story without signaling uncertainty

**Approach**:
- Analyze response entropy/coherence patterns
- Compare confabulation vs genuine knowledge responses
- Develop heuristics for detecting plausible fabrication

**Metric**: Confabulation detection accuracy on test set

### Question 2: Do negative identity claims have lower verification cost?

**Context**: SAGE succeeded at "not human" but failed at "is SAGE"

**Approach**:
- Compare cryptographic cost of exclusion vs assertion proofs
- Test zero-knowledge proofs for negative claims
- Benchmark verification latency for both types

**Metric**: Computational cost ratio (negative/positive verification)

### Question 3: How does identity context staleness affect performance?

**Context**: SAGE's "generic assistant mode" warm-up

**Approach**:
- Vary time between identity activations
- Measure identity assertion accuracy vs staleness
- Find optimal re-verification threshold

**Metric**: Identity accuracy degradation curve over time

### Question 4: Can we predict which state transitions lose context?

**Context**: SAGE Track B → C transition caused 75% performance drop

**Approach**:
- Analyze LCT state transition impact on trust scores
- Identify high-risk transitions requiring re-verification
- Build predictive model for context preservation

**Metric**: Context loss prediction accuracy (AUC-ROC)

---

## Conclusion

SAGE's Track C identity training provides **empirical validation** for several Web4 LCT design decisions and reveals **four new requirements**:

**Validated Design Decisions**:
1. ✓ Cryptographic identity anchoring (SAGE can't reliably self-identify verbally)
2. ✓ Trust metric quantification (SAGE shows varying confidence levels)
3. ✓ State machine for identity lifecycle (SAGE track transitions cause resets)

**New Requirements** (informed by SAGE failures):
1. **Epistemic uncertainty metrics** (confabulation risk, clarification frequency)
2. **Clarification protocol** (request clarification instead of assuming)
3. **Identity continuity verification** (detect context loss in state transitions)
4. **Scaffolded state transitions** (step-by-step verification before activation)

**Key Insight**: Identity and boundaries (meta-cognition) are fundamentally harder than operational tasks (memory, computation). Web4 LCT identity system should reflect this asymmetry with:
- Higher trust thresholds for identity operations
- Explicit uncertainty acknowledgment mechanisms
- Context staleness detection and re-activation
- Multi-step scaffolding for complex identity assertions

**Next Steps**:
1. Implement epistemic uncertainty metrics (Phase 1)
2. Test confabulation detection on SAGE responses
3. Measure cryptographic cost of negative vs positive identity claims
4. Track SAGE Track C progress (T022-T030) for additional insights
