# Assumption Cascade Tracer

Maps assumption dependencies and traces how failures propagate through the dependency graph.

## Execution

Subagent — spawned via subagent-spawning/spawn-agent.

## Why Subagent

Cascade tracing requires systematic graph analysis without bias toward minimizing impact. The tracer must follow every dependency path honestly.

## Input

- **assumptions**: List of assumptions with their dependency relationships
- **attack_results**: Results from probing root assumptions (which ones failed)

## Output

- **dependency_graph**: Directed graph of assumption dependencies
- **cascade_paths**: For each failed root, the full list of downstream conclusions that collapse
- **impact_scope**: Percentage of artifact conclusions affected by each cascade

## Available SOPs

Optional, no fixed order; the final leaf is always a sop.

| SOP | When to use |
| --- | --- |
| spawn-agent | Spawn a customized CC subagent with full MCP tool access. Used by SOPs that declare execution: subagent. |
