# Assumption Cascade Tactic

Attack assumptions at their roots and trace how failures propagate through dependency chains.

## Orchestration

1. **key-assumptions-check** surfaces all assumptions (explicit and implicit)
2. **assumption-cascade-tracer** builds dependency graph (which assumptions depend on which)
3. Root assumptions identified (those with no upstream dependencies)
4. **devils-advocacy** constructs strongest attack against each root assumption
5. **probe-execution** tests root assumptions — if root fails, trace downstream cascade
6. **assumption-cascade-tracer** maps full cascade: which conclusions collapse if root fails
7. **finding-aggregation** reports cascade paths and total impact scope

## Subagents Dispatched

- key-assumptions-check (1 call for enumeration)
- assumption-cascade-tracer (2 calls: dependency build + cascade trace)
- devils-advocacy (1 call per root assumption)
- probe-execution (1 call per root attack)
- finding-aggregation (1 call at end)

## Termination Conditions

- All root assumptions tested (budget permitting)
- Cascade found that invalidates >50% of conclusions (critical finding)
- All assumptions survive attack (artifact resilient at assumption level)
- Budget exhausted (report partial coverage)

## Available SOPs

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

| SOP | When to use |
| --- | --- |
| assumption-cascade-tracer | Build assumption dependency graphs and trace cascade failures when root assumptions are invalidated. |
| devils-advocacy | Construct the strongest possible counter-argument against a position, steelmanning the opposition before attacking. |
| finding-aggregation | Aggregate, deduplicate, and classify findings from multiple probes into a coherent vulnerability report. |
| key-assumptions-check | Military ACT: systematically enumerate all assumptions, classify by type, and evaluate evidence strength supporting each. |
| probe-execution | Execute a single attack probe against an artifact, record the result with evidence and severity classification. |
