Evidence

Supporting Evidence

src/cas_runner/steering/models.py (PromptFact, SteeringRuntimeIndex, CapabilityRecord, ArchitecturalDelta) - Typed models defining fact indexing and runtime projection

Scope Assessment

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

Rationale

Intent: Supply agents with factual, verifiable context without flooding prompts with unstructured data or ungrounded knowledge.
Context: Agents analyzing git changes and governance compliance require precise context regarding capability lineages and repository deltas.
Force: LLMs hallucinate context when provided ambiguous or unstructured raw git dumps.
Force: Prompt token budgets require concise, relevant summaries of current system architecture.
