From 85685dbdd03deb377d510c351547b3d24d5eafa1 Mon Sep 17 00:00:00 2001 From: Imran Siddique Date: Wed, 18 Mar 2026 14:00:21 -0700 Subject: [PATCH 1/6] feat(security): harden against agent sandbox escape vectors Address 3 critical gaps identified in Ona/Veto agent security research: 1. Tool content hashing (defeats tool aliasing/wrapping attacks): - ToolRegistry now computes SHA-256 hash of handler source at registration - execute_tool() verifies integrity before execution, blocks on mismatch - New ContentHashInterceptor in base.py for intercept-level hash verification - Integrity violation audit log with get_integrity_violations() 2. PolicyEngine freeze (prevents runtime self-modification): - New freeze() method makes engine immutable after initialization - add_constraint, set/update_agent_context, add_conditional_permission all raise RuntimeError when frozen - Full mutation audit log records all operations (allowed and blocked) - is_frozen property for inspection 3. Approval quorum and fatigue detection (defeats approval fatigue): - New QuorumConfig dataclass for M-of-N approval requirements - EscalationHandler supports quorum-based vote counting - Fatigue detection: auto-DENY when agent exceeds escalation rate threshold - Per-agent rate tracking with configurable window and threshold - EscalationRequest.votes field tracks individual approver votes All changes are backward-compatible: new parameters are optional with defaults that preserve existing behavior. 33 new tests, 53 total pass.

Restore the working pattern for test deps while keeping hash verification for the lint requirements file.
