feat(governance): Implement strategic trust framework with trust scoring

[adwiteeymauriya]

Description

Implement a strategic trust framework that provides verifiable trust through transparent decision trails and trust scoring.

Trust Layers

Policy-Aligned Reasoning

• Embed policies in prompt engineering
• Constitutional AI-style constraints
• Hard stops for policy violations
• AI cannot generate decisions outside approved boundaries

Data Sensitivity Awareness

• Automatic classification detection
• Context-appropriate controls
• Classification-based processing rules:
  • Public: Standard processing, minimal controls
  • Internal: Access logging, basic redaction
  • Confidential: Strict access control, full audit
  • Restricted: Approval required, encryption, limited retention

Scenario-Aware Oversight

Evaluate contextual factors before every action:

• Temporal: time of day, deadline pressure, data freshness
• Source: request origin, user history, channel
• Purpose: stated intent, inferred intent, historical pattern
• Constraints: regulatory, organizational, technical

Transparent Decision Trails

Complete audit for every AI decision:

• Decision ID and timestamp
• Context snapshot at decision time
• Reasoning chain
• Data sources used
• Policies applied
• Controls triggered
• Final outcome with confidence

Trust Scoring

scorer = TrustScorer()

# Score an entity
trust_score = await scorer.score_entity(
    entity_id="user_123",
    factors={
        "history_length": 365,
        "violation_count": 0,
        "verification_level": "2fa",
        "behavior_consistency": 0.95,
    },
)

# Score a decision
decision_trust = await scorer.score_decision(
    decision_id="dec_abc123",
    factors={
        "data_quality": 0.9,
        "model_confidence": 0.85,
        "guardrails_passed": True,
        "human_verified": False,
    },
)

API Design

GET /api/v1/governance/trust/score/{entity_id}
GET /api/v1/governance/trust/audit/{decision_id}
GET /api/v1/governance/trust/audit?user_id=X&date_from=Y

Acceptance Criteria

• Trust scoring for entities implemented
• Trust scoring for decisions implemented
• Complete decision audit trail capture
• Audit trail query API
• Trust decay over time
• Trust recovery mechanisms
• Integration with governance dashboard
