Systematic Perturbation

Map validity by perturbing along defined axes.

Operations

• variation-axis-definition → controlled-perturbation → validity-envelope-construction

Available SOPs

Subagent: variation-axis-definition, controlled-perturbation, validity-envelope-construction Import: paper-search

Execution Guidance

Define orthogonal axes of variation (at least 3), perturb one axis at a time while holding others constant, record performance at each point, construct envelope from degradation thresholds.

Minimum Yield

<HARD-GATE>
- variation axes defined: >= 3
- perturbation curves: >= 3
- validity envelope: >= 1 constructed
</HARD-GATE>

Available SOPs

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

SOP	When to use
controlled-perturbation	Systematically vary parameters along defined axes, recording performance at each point to identify degradation thresholds.
deep-insight-paper-search	AI-powered paper summary and search. Import of literature-engine/literature-search skill. AI summary level — cite as "AI-extracted" not "paper states".
deep-insight-validity-envelope-construction	Combine multi-axis perturbation data into a multi-dimensional validity description with boundary conditions and interaction effects.
variation-axis-definition	Identify orthogonal axes along which a method's validity might vary. Ensures axes are independent, measurable, and span the relevant parameter space.
