The value of a digital asset identity depends entirely on the integrity of its validation process. The Vecoris Trust Engine, implemented within the @vecoris/intelligence-engine and @vecoris/capability-engine packages, executes programmatic scoring and data conflict resolution to compile the final asset Trust Index.

1. Trust Index Calculation Metrics

The Trust Index is not a static flag. It is a dynamically calculated percentage (ranging from 0% to 100%) computed by weighting verification outputs across three core vectors:

1. Title Record Security (40% Weight): Evaluates the presence of active disputes, mortgage encumbrances, or civil court litigation. If RERA connectors find clean, unencumbered titles, this vector scores 100%.
2. Boundary and GIS Compliance (35% Weight): Compares coordinates registered in municipal records with spatial survey records. Encroachments or mismatched boundary shapes trigger penalties.
3. Document and Verification Integrity (25% Weight): Checks the hash validity of submitted title files, field photos, and land tax receipts. Unsigned or missing documents reduce this vector score.

2. Multi-Source Conflict Resolution

When multiple registries return contradictory values for the same asset property (for example, municipal land records show owner A, but a civil court database lists active litigation from claimant B), the trust engine executes deterministic conflict resolution rules:

• Litigation Dominance: Court records always override tax registry ownership assumptions, immediately flagging the asset's title index as "Disputed" and reducing the score.
• Timestamp Priority: If two RERA filings conflict, the latest timestamped record is prioritized, but the variance is flagged as a title discrepancy for review.

3. Auditable History Trails

Every scoring change, rule execution, or resolved dispute is logged in the database, signing the transition history with user and API client stamps. This ensures that the timeline of an asset is explainable and audit-compliant for enterprise due diligence checks.
