Pattern Proposal: Capability Lineage Anchoring

Summary

Tracks explicit provenance and evolution history across capability definitions using typed lineage records.

Candidate Pattern

• ID: capability-lineage-anchoring
• Classification: architectural
• Maturity: established
• Type: implemented

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/steering/models.py (CapabilityLineage, CapabilityRecord, CapabilitySet) - Defines schemas for capability tracking and lineage.

Scope Assessment

• Evidence Strength: high
• Confidence: high
• Applies to: ideas-to-life-cas

Rationale

• Intent: Ensure that as agents propose or modify capability definitions, the derivation history and parent links remain uncorrupted.
• Context: Governs capability evolution across projects and the global cas-knowledge base.
• Force: Repeated agent modifications erase initial authorship or source policy references.
• Force: Difficult to assess the blast radius of an upstream template change without parent links.
