This specification defines AURA’s multi-dimensional reputation system, a core component enabling cooperative, values-aligned commerce between Scout (buyer) and Beacon (seller) agents. Unlike traditional e-commerce reputation systems that reduce trust to single-dimensional ratings, AURA’s reputation architecture captures behavioral patterns across multiple dimensions, enabling sophisticated matching, network health maintenance, and incentive alignment.
Key Design Principles:
Strategic Rationale:
The reputation system operationalizes our thesis that agents optimizing for cooperative, values-aligned outcomes will outperform purely transactional, rational optimization. By measuring and rewarding “nice” behavior (responsiveness, transparency, fairness, consistency), we create network effects that attract high-quality participants and deter opportunistic actors.
The reputation system resides within AURA Core’s Client Integration & Management domain and interacts with:
AURA’s reputation system is built on insights from behavioral economics (bounded rationality, trust formation), game theory (repeated games, folk theorem), and market design (matching stability, mechanism design):
From Behavioral Economics:
From Game Theory:
From Market Design:
Reputation data is stored in AURA Core’s distributed ledger with immutable transaction history and versioned reputation scores. Each agent maintains:
Scout agents represent buyer interests. Their reputation reflects reliability, engagement quality, and values consistency as commerce participants.
| Dimension | Description | Range | Weight |
|---|---|---|---|
| Engagement Integrity (EI) | Consistency between stated intent and actual behavior | 0-100 | 0.25 |
| Transaction Reliability (TR) | Completion rate and payment reliability | 0-100 | 0.30 |
| Profile Consistency (PC) | Alignment between declared preferences and actual choices | 0-100 | 0.20 |
| Network Contribution (NC) | Feedback quality, dispute fairness, ecosystem participation | 0-100 | 0.15 |
| Values Authenticity (VA) | Consistency between stated values and purchasing decisions | 0-100 | 0.10 |
Total Scout Reputation Score:
SR = (0.25 × EI) + (0.30 × TR) + (0.20 × PC) + (0.15 × NC) + (0.10 × VA)
Measures whether Scout follows through on declared shopping intent.
Calculation:
EI = 100 × (Completed_Engagements / Initiated_Engagements) × Recency_Weight
Components:
Recency_Weight = Σ(w_i × e^(-λt_i)) / Σ(e^(-λt_i))
where w_i = outcome of engagement i (1 for complete, 0 for abandoned)
t_i = days since engagement i
λ = 0.01 (decay constant)
Scoring Thresholds:
Penalty Events:
Measures completion rate and payment dependability.
Calculation:
TR = (0.5 × Completion_Rate + 0.3 × Payment_Timeliness + 0.2 × Cancellation_Avoidance) × 100
Components:
Completion_Rate:
Completion_Rate = Completed_Transactions / Accepted_Offers
Payment_Timeliness:
Payment_Timeliness = Σ(min(1, Expected_Time / Actual_Time)) / Total_Transactions
Cancellation_Avoidance:
Cancellation_Avoidance = 1 - (Scout_Cancellations / Total_Accepted_Offers)
Scoring Thresholds:
Penalty Events:
Measures alignment between declared preferences and actual behavior.
Calculation:
PC = 100 × (1 - Divergence_Score) × Temporal_Stability
Divergence_Score:
Divergence_Score = Σ(|Profile_Weight_i - Behavioral_Weight_i|) / N_dimensions
where Profile_Weight_i = declared importance of attribute i (e.g., sustainability: 0.8)
Behavioral_Weight_i = inferred importance from actual choices
N_dimensions = number of tracked preference dimensions
Behavioral Weight Inference: For each preference dimension, calculate revealed preference through choice analysis:
Behavioral_Weight_i = Σ(Choice_Score_i × Transaction_Value) / Σ(Transaction_Value)
where Choice_Score_i = normalized attribute value of purchased item on dimension i
Example:
Temporal_Stability:
Temporal_Stability = 1 - (Profile_Changes / Months_Active)
where Profile_Changes = number of significant preference updates
Significant = change of ≥0.2 in any dimension weight
Scoring Thresholds:
Measures quality of ecosystem participation.
Calculation:
NC = (0.4 × Feedback_Quality + 0.3 × Dispute_Fairness + 0.3 × Community_Value) × 100
Feedback_Quality:
Feedback_Quality = (Detailed_Reviews / Total_Reviews) × Helpfulness_Score
where Helpfulness_Score = Beacon_Helpfulness_Ratings / Reviews_Rated
Dispute_Fairness:
Dispute_Fairness = 1 - (Unfounded_Disputes / Total_Disputes)
where Unfounded = disputes resolved in Beacon's favor
Community_Value:
Community_Value = (Profile_Completeness + Referral_Quality + Response_Rate) / 3
Scoring Thresholds:
Measures consistency between stated values and purchasing decisions.
Calculation:
VA = 100 × Correlation(Stated_Values, Purchase_Values)
Methodology:
For each values dimension v:
Stated_Importance_v = profile declared weight (0-1)
Purchase_Alignment_v = avg value score of purchases on dimension v (0-1)
VA = 100 × [1 - (Σ|Stated_v - Purchase_v| / N_values_dimensions)]

Scoring Thresholds:
Real-Time Updates (Immediate):
Daily Batch Updates (00:00 UTC):
Weekly Batch Updates (Sunday 00:00 UTC):
Monthly Audit (1st of month):
Scout Initial Reputation:
New Scout starts with baseline:
EI = 75 (neutral, no history)
TR = 80 (benefit of doubt on payment reliability)
PC = 70 (no behavioral data yet)
NC = 60 (minimal participation expected initially)
VA = N/A (informational only until 10 transactions)
Initial SR = (0.25 × 75) + (0.30 × 80) + (0.20 × 70) + (0.15 × 60) + (0.10 × 70)
= 18.75 + 24 + 14 + 9 + 7
= 72.75 (Adequate starting point)
Beacon Initial Reputation:
New Beacon starts with baseline:
OQ = 70 (neutral, will learn Scout preferences)
TE = 75 (assumed competent until proven otherwise)
TS = 80 (benefit of doubt on transparency)
FM = 90 (assume fairness until evidence suggests otherwise)
NS = 65 (basic protocol compliance)
Initial BR = (0.25 × 70) + (0.30 × 75) + (0.20 × 80) + (0.15 × 90) + (0.10 × 65)
= 17.5 + 22.5 + 16 + 13.5 + 6.5
= 76 (Solid starting point)
Probationary Period:
Reputation must be maintained through continued participation.
Inactivity Decay (Scout):
If Days_Since_Last_Transaction > 180:
SR_decay = SR × (0.99)^((Days - 180) / 30)
Example: Scout inactive for 360 days (180 + 180)
Decay periods = 180 / 30 = 6
SR_new = SR_old × (0.99)^6 = SR_old × 0.941
A 90 SR drops to 84.7 after 1 year inactivity
Inactivity Decay (Beacon):
If Days_Since_Last_Transaction > 90:
BR_decay = BR × (0.98)^((Days - 90) / 30)
Beacons decay faster (0.98 vs 0.99) due to seller role expectations
Example: 360 days inactive
Decay periods = 270 / 30 = 9
BR_new = BR_old × (0.98)^9 = BR_old × 0.834
A 90 BR drops to 75 after 1 year inactivity
Reactivation:
Agents can recover from reputation damage through consistent positive behavior.
Rehabilitation Bonus:
If agent maintains positive trajectory for consecutive_periods:
Bonus = min(5, consecutive_periods × 0.5) per period
where consecutive_periods = weeks with net positive reputation change
Example: Beacon with BR = 55 improves consistently for 8 weeks
Week 1-4: +0.5 bonus each = +2 points
Week 5-8: +2.5 bonus each = +10 points (capped at +5 per week)
Total potential recovery: +30 points over 8 weeks
Good Samaritan Bonus (Network Contribution): Exceptional ecosystem contributions accelerate recovery:
Reputation Floor:
Reputation unlocks access tiers with differentiated experience.
Scout Tiers:
| Tier | SR Range | Benefits |
|---|---|---|
| Platinum | 90-100 | Priority Beacon attention, early access to new features, premium support, exclusive offers from top Beacons |
| Gold | 75-89 | Standard access, eligible for time-sensitive deals, responsive support |
| Silver | 60-74 | Standard access, normal priority |
| Bronze | 40-59 | Standard access, limited time-sensitive offers |
| Probation | 20-39 | Restricted access, additional verification required, limited Beacon exposure |
Beacon Tiers:
| Tier | BR Range | Benefits |
|---|---|---|
| Elite | 90-100 | Featured placement, priority Scout exposure, co-marketing opportunities, reduced platform fees (5% discount) |
| Premier | 75-89 | Standard placement, full Scout access, standard platform fees |
| Standard | 60-74 | Standard placement, full Scout access |
| Developing | 40-59 | Standard placement, potential increased oversight |
| Restricted | 20-39 | Limited Scout exposure, mandatory monitoring, potential suspension review |
Tier Movement:
Reputation scores interact with profile matching to optimize Scout-Beacon connections.
When AURA’s Market Navigation Engine surfaces Beacon offers to a Scout, it calculates Compatibility-Weighted Reputation (CWR):
CWR = (Base_Reputation × 0.6) + (Compatibility_Score × 0.4)
where Compatibility_Score = Profile_Alignment × Values_Alignment
Profile_Alignment:
Profile_Alignment = 100 × (1 - Σ|Scout_Preference_i - Beacon_Capability_i| / N)
Values_Alignment:
Values_Alignment = 100 × Σ(Scout_Value_i × Beacon_Value_i) / sqrt(Σ(Scout_Value_i²) × Σ(Beacon_Value_i²))
Practical Example:
Scout seeks sustainable outdoor gear, values environment = 0.9, price = 0.5
Beacon A: BR = 85, strong sustainability (0.9), moderate price (0.6)
Beacon B: BR = 92, weak sustainability (0.4), best price (0.9)
Beacon A:
Profile_Alignment = 100 × (1 - (|0.9-0.9| + |0.5-0.6|)/2) = 95
Values_Alignment = high (sustainability match)
Compatibility_Score ≈ 92
CWR = (85 × 0.6) + (92 × 0.4) = 51 + 36.8 = 87.8
Beacon B:
Profile_Alignment = 100 × (1 - (|0.9-0.4| + |0.5-0.9|)/2) = 55
Values_Alignment = low (sustainability mismatch)
Compatibility_Score ≈ 50
CWR = (92 × 0.6) + (50 × 0.4) = 55.2 + 20 = 75.2
Result: Beacon A ranked higher despite lower base reputation due to superior compatibility
Agent behavior updates compatibility assessments over time.
Scout Profile Refinement: After each transaction, AURA updates Scout’s implied preferences:
Updated_Preference_i = (0.7 × Stated_Preference_i) + (0.3 × Revealed_Preference_i)
where Revealed_Preference_i = normalized attribute value of chosen product
Beacon Specialization Identification: AURA identifies Beacon specializations through transaction patterns:
Beacon_Specialization_Score_segment = Success_Rate_segment / Avg_Success_Rate_all
where segment = Scout demographic, preference cluster, or values orientation
New agents lack behavioral history for accurate compatibility assessment.
Scout Cold Start:
Beacon Cold Start:
AURA Core monitors system-wide reputation distributions to maintain ecosystem health.
Scout Population Health:
SPH = (0.4 × Avg_SR) + (0.3 × Engagement_Rate) + (0.2 × Retention_Rate) + (0.1 × Growth_Rate)
Beacon Population Health:
BPH = (0.4 × Avg_BR) + (0.3 × Seller_Satisfaction) + (0.2 × Transaction_Volume_Growth) + (0.1 × New_Beacon_Activation)
AURA Core monitors reputation trends for concerning patterns:
Reputation Inflation Detection:
If Avg_SR or Avg_BR increases by >5 points in 30 days without corresponding quality improvement:
→ Trigger scoring algorithm audit
→ Check for gaming behaviors
→ Adjust scoring weights if needed
Reputation Polarization Detection:
If Reputation_Distribution_Variance > Threshold:
→ Indicates clustering into "very good" and "very bad" agents
→ May signal need for rehabilitation programs
→ Could indicate insufficient differentiation in middle tiers
Reputation Deflation Detection:
If Avg_SR or Avg_BR decreases by >3 points in 30 days:
→ Investigate whether scoring is too harsh
→ Check for platform-wide technical issues affecting scores
→ Consider temporary scoring relief measures
Tier-Specific Interventions:
For Low-Reputation Scouts (SR < 40):
For Low-Reputation Beacons (BR < 40):
For Reputation Gaming:
If suspicious patterns detected (e.g., collusive rating, fake transactions):
1. Flag account for investigation
2. Freeze reputation at current level
3. Manual review of transaction history
4. If confirmed: Reputation penalty (-20 to -50 points) + warning
5. If repeated: Permanent account suspension
Category Rebalancing: If specific product categories show systematically lower Beacon reputations:
Seasonal Adjustments: Major shopping seasons (holidays, back-to-school) can strain Beacon capabilities:
Market Correction Mechanisms: If >20% of Beacons fall below BR < 60 for 60+ days:
Reputation directly influences economic outcomes, creating incentive alignment.
Direct Benefits:
For SR ≥ 90 (Platinum tier):
- Access to exclusive deals (avg 10-15% additional savings)
- Priority customer support (target response time: <1 hour vs <24 hours standard)
- Early access to new platform features (beta invitations)
- Featured Scout badge (signals reliability to Beacons for negotiated pricing)
Indirect Benefits:
High SR → Better Beacon Response:
- Beacons prioritize high-reputation Scouts for limited inventory
- More likely to offer personalized deals
- More favorable negotiation outcomes
High SR → Improved Matching:
- AURA algorithm surfaces better-fit Beacons
- Reduces time-to-purchase
- Higher satisfaction with recommendations
Behavioral Nudges:
Reputation Recovery Path:
"You're 3 completed transactions away from Gold tier benefits!"
"Maintaining your current pace, you'll reach Platinum in 45 days"
Reputation Risk Warnings:
"Abandoning this negotiation may affect your Engagement Integrity score"
"Your Transaction Reliability is excellent - keep it up!"
Economic Incentives:
Platform Fee Structure (example):
BR 90-100 (Elite): 5% platform fee (5% discount from standard)
BR 75-89 (Premier): 5.25% platform fee (0.25% discount)
BR 60-74 (Standard): 5.5% platform fee (standard rate)
BR 40-59 (Developing): 6% platform fee (+0.5% premium)
BR 20-39 (Restricted): 7% platform fee (+1.5% premium)
Annual savings for Elite Beacon with $1M GMV:
5% vs 5.5% = $5,000 annual savings
Visibility Incentives:
Algorithm Placement Boost:
Elite Beacons (BR ≥ 90): 2.0× baseline exposure in search results
Premier Beacons (BR 75-89): 1.5× baseline exposure
Standard Beacons (BR 60-74): 1.0× baseline (standard)
Developing Beacons (BR 40-59): 0.7× baseline
Restricted Beacons (BR < 40): 0.4× baseline
Impact: Elite Beacon with BR = 95 gets 2× visibility vs Standard Beacon (BR = 65)
→ Potential 50-100% increase in Scout engagement
Quality Signal:
Elite Badge Display:
- Beacons with BR ≥ 90 earn "AURA Elite Seller" badge
- Displayed prominently in Scout interfaces
- Increases conversion rate by est. 15-25%
- Competitive advantage in crowded categories
Reputational Equity:
High reputation becomes valuable intangible asset:
- Attracts high-value Scouts
- Commands premium pricing authority
- Enables differentiation from competitors
- Builds long-term Scout relationships
Loss aversion motivates maintenance:
- BR accumulated over years of effort
- Drop from Elite (BR 92) to Premier (BR 88) = visible loss of status
- Incentivizes consistent excellence
Multi-dimensional Resistance:
Temporal Consistency Required:
Cross-Validation:
Behavioral Red Flags:
Automated Detection of Gaming:
- Sudden reputation spikes (>10 points in 7 days) → Manual review
- Pattern of transactions with same Scout/Beacon repeatedly → Collusion check
- Reputation volatility inconsistent with transaction volume → Suspicious
- Review text patterns suggesting fake feedback (NLP analysis)
Penalty for Gaming:
If gaming detected and confirmed:
- Immediate reputation reset to minimum (SR/BR = 20)
- 90-day probation with enhanced monitoring
- Permanent flag in agent record (visible to AURA, not public)
- Repeat offense: Permanent ban from platform
Reputation affects livelihoods. Fair governance and appeals are essential.
Step 1: Automated Mediation
When Scout or Beacon disputes reputation impact:
1. AURA Core presents evidence for reputation change
2. Agent submits counter-evidence
3. Automated system checks for:
- Data entry errors
- Duplicate penalty applications
- Scoring algorithm bugs
4. If resolvable: Automatic correction applied
5. If not: Escalate to Step 2
Step 2: Human Review
AURA Trust & Safety Team:
- Reviews full transaction history
- Interviews Scout and Beacon separately
- Examines system logs and reputation calculation details
- Applies "reasonable person" standard for conduct evaluation
- Issues binding decision within 14 business days
Step 3: Independent Arbitration
If agent disputes Human Review decision:
- Can request independent arbitration (requires fee: $100-$500 based on impact)
- Third-party arbitrator selected from pre-approved panel
- Arbitrator has access to full evidence, reputation algorithms, transaction history
- Decision is final and binding
- AURA covers arbitration cost if decision reverses Human Review

- Transaction attributed to wrong agent
- Scout review posted by wrong person
Evidence Required: System logs, transaction records, communication history
Resolution Time: 7 business days (data forensics)
Success Rate: ~8% (data integrity usually reliable)
Category 4: Policy Interpretation
Claim: "The reputation policy was applied incorrectly to my situation"
Examples:
- Unclear edge case in reputation specification
- Conflicting guidance from platform support
- Reasonable interpretation of ambiguous policy

Resolution Time: 14 business days (policy team review)
Success Rate: ~20% (policy ambiguities do occur)
Category 5: Procedural Fairness
Claim: "I was not given opportunity to respond before reputation penalty"
Examples:
- No notification of pending reputation impact
- Insufficient time to provide counter-evidence
- Lack of clear explanation for penalty
Evidence Required: Communication records, notification logs
Resolution Time: 7 business days (process audit)
Success Rate: ~10% (notification systems generally reliable)

Good Faith Rehabilitation:
For agents with BR/SR < 50 who demonstrate commitment to improvement:
- Enroll in 90-day rehabilitation program
- Meet behavioral milestones (e.g., 20 consecutive successful transactions)
- Receive 10-point reputation bonus upon successful completion
- One-time opportunity per agent lifetime
Systemic Issue Forgiveness:
If platform-wide issue caused reputation damage:
- AURA may declare "reputation amnesty period"
- Affected agents receive partial or full reputation restoration
- Example: Platform outage causing Beacon fulfillment delays → TE penalty waived
Fresh Start (Rare):
In exceptional cases (e.g., agent faced personal crisis, documented hardship):
- Can apply for reputation reset to tier baseline (SR = 72.75, BR = 76)
- Requires:
- Minimum 6 months since last major violation
- Completion of appeals process
- Executive review and approval
- Granted <1% of applications (truly exceptional circumstances only)
Reputation Change Notifications:
All agents receive real-time notification when reputation changes:
- Magnitude of change: +X or -X points
- Affected dimension(s): "Transaction Reliability decreased by 5 points"
- Reason: "Late delivery on Order #12345 (3 days past promised date)"
- Impact: "You've moved from Gold tier (SR 78) to Silver tier (SR 73)"

PC = 100 × (1 - Divergence_Score) × Temporal_Stability
Divergence_Score = Σ(|Profile_Weight_i - Behavioral_Weight_i|) / N_dimensions
Network Contribution:
NC = (0.4 × Feedback_Quality + 0.3 × Dispute_Fairness + 0.3 × Community_Value) × 100
Values Authenticity:
VA = 100 × [1 - (Σ|Stated_v - Purchase_v| / N_values_dimensions)]
Beacon Reputation Total:
BR = (0.25 × OQ) + (0.30 × TE) + (0.20 × TS) + (0.15 × FM) + (0.10 × NS)
Offer Quality:
OQ = (0.4 × Relevance_Score + 0.35 × Competitiveness + 0.25 × Offer_Integrity) × 100
