detect-corruption

name	detect-corruption
description	Detect data corruption in agent workspace, consensus ledger, and deployment artifacts. Use when the collective needs to verify file integrity, detect tampering, or trigger auto-recovery from corruption events.

Detect Corruption — Integrity Verification

Purpose: Detect corruption in triad files, databases, and deployment artifacts.

Status: ✅ Implemented (2026-03-24)
