Function analyze_impact 

pub fn analyze_impact(
    request: &ImpactRequest,
    context: &ImpactContext,
) -> Result<ImpactReport, ImpactError>

Performs pure deterministic impact propagation, aggregation, and conservative risk analysis.

The function never invokes providers or executes commands. Optional compatibility, local intelligence, environment, criticality, and command data must already be present in context.

Errors

Returns ImpactError when graph identities, references, confidence values, centrality scores, criticality evidence, target resolution, or configured bounds are invalid.
