SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) and scripts (resource) components.

What problem does it solve?

This Skill traces the upstream and downstream lineage of a single artifact within the evidence graph, providing a completeness score and identifying gaps without needing to rebuild the entire graph.

Core Features & Use Cases

  • Artifact Lineage Tracing: Follows the path of an artifact from its objective root to its benefit node.
  • Completeness Scoring: Calculates a score based on the presence of expected stages in the artifact's chain.
  • Gap Identification: Lists missing stages and provides an audit readiness verdict.
  • Use Case: Quickly assess the regulatory compliance status of a specific feature by tracing its evidence chain and identifying any missing approval or test stages.

Quick Start

Trace the evidence chain for artifact EVD-12345 and report its completeness score.

Frequently Asked Questions about evidence-chain

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check the completeness score of a single artifact in an evidence graph?▼

To check the completeness score of an artifact in an evidence graph, provide its specific artifact ID or file path. The system analyzes it against a graph index and schema to calculate a score based on the presence of expected stages in the chain.

What is evidence chain lineage tracing and how does it identify missing audit stages?▼

Evidence chain lineage tracing follows the path of an artifact from its objective root to its benefit node within an evidence graph. It identifies missing audit stages by comparing the existing artifact chain against expected stages defined in the schema.

How can I quickly assess the regulatory compliance status of a specific feature for audit readiness?▼

You can assess regulatory compliance status by tracing the evidence chain for a specific feature artifact. The system provides an audit readiness verdict by listing any missing approval or test stages in the artifact's lineage path.

Can I trace artifact lineage using file paths instead of artifact IDs?▼

Yes, you can trace artifact lineage using file paths. The system analyzes both artifact IDs like EVD-NNN, WI-NNN, CHAIN-NNN and file paths against the graph index to report upstream and downstream connections.

Does tracing a single artifact's evidence chain require rebuilding the entire graph?▼

No, tracing a single artifact's evidence chain does not require rebuilding the entire graph. The system queries the existing graph index and schema to report on upstream and downstream connections and stage presence independently.
