Pattern Proposal: Steering capability and delta modeling

Summary

Steering-related data is modeled as structured records for Git deltas, capability records, capability sets, lineage, and architectural deltas.

Candidate Pattern

• ID: steering-capability-delta-modeling
• Classification: architectural
• Maturity: emerging
• Type: emerging

Observed Signals

No specific signals listed.

Evidence

Supporting Evidence

• src/cas_runner/steering/models.py (GitChangeType, RawGitDelta, PromptFact, SteeringRuntimeIndex, CapabilityCategory, CapabilityRecordType, CapabilityRecord, CapabilitySet, CapabilityLineage, ArchitecturalDelta) - Symbols include prompt-adjacent data fields, but the structural pattern is the data shape and normalization, not prompt orchestration.

Scope Assessment

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

Rationale

• Intent: Represent architectural change and capability context in a normalized, queryable form.
• Context: The steering subsystem needs to reason about repository changes and runtime capability indexes.
• Force: Git changes must be normalized before analysis
• Force: Capability records need lineage and grouping
• Force: Architectural deltas need a stable payload shape
