assay — Mutation Review & Adversarial Quality Engine

Domain Rubric

Inspect mutation artifacts against 4 structural dimensions:

Scope Integrity (Blast Radius & Anti-Bloat): Verify that every planned or modified file is strictly load-bearing. Flag accidental formatting, cosmetic churn, unrelated refactoring, speculative files, or lingering dead code left unpruned after replacement.
Contract & Spec Fidelity (Anti-Drift): Reconcile changes against governing specifications, SSOT documents, and established interfaces. Flag undocumented behavioral changes or broken contracts.
Structural Cohesion & Slicing: Verify modular encapsulation without leaky abstractions. For tasks, verify true vertical slicing (end-to-end capability) over horizontal layer fragmentation.
Operational Hygiene & Safety: Expose unhandled edge cases, resource leaks, lingering debug probes ([DEBUG-<hex>]), unredacted secrets, or unpurged transient scratch/task files.

PASS: Zero structural or contract defects; blast radius is minimal and strictly load-bearing; ready for execution or commit.
CONDITIONAL: Minor defects observed (accidental churn, missing edge test, localized bloat); actionable remediation provided to unblock.
FAIL: Critical defects detected (contract violation, unauthorized blast radius, fake vertical slice, regression risk); reject and halt.
