Proving Live-Target Vulnerabilities Without Sending Destructive Packets to the Network Socket
Security officers often forbid active vulnerability scanning on live systems because a stray test packet can erase a table or crash a service. The platform solves this by placing a software filter inside the scanner itself that blocks every destructive command before the network socket opens.
Active penetration testing traditionally forces organizations to choose between realism and operational safety. Running aggressive exploit payloads against production-like environments risks corrupting relational tables, deleting filesystem records, or triggering outbound webhooks to partners. Conversely, passive configuration reviews miss deep authorization and injection flaws.
Security Officer (Plain Meaning): Halts "Transmit destructive SQL DDL, recursive filesystem deletion, or out-of-scope HTTP 302 redirect to live socket" before socket (0 live DB damage, signed GOST receipt)

Deterministic verification flow for IB30-ZHS-03 (Security 3.0 Axiom III / SafeActionSandbox, In-Path Wire Interceptor): wire rule SEC-ZD-IB30-03 evaluates the formal invariant prior to socket transmission, witness e703d948a15c2f83 seals the empirical proof, and compiler emits gateway contract IMMUNE-IB30-E703D948 for mcp-sentinel.
2. Mathematical Formulation and Solver Invariant for IB30-ZHS-03
The INDRA platform eliminates this hazard through a three-layer in-path containment mechanism implemented in zero_damage_sandbox.py under rule SEC-ZD-IB30-03. Before any candidate probe reaches the operating system socket, it passes through ScopeGuard host allowlisting and ScopedRedirectHandler inspection on every 301, 302, 307, and 308 hop. A syntax-tree filter then halts table drops, bulk deletions, and shell mutations.
In addition, resource-exhaustion checks (DOS-RSRC and AI-DOW-10) are structurally separated into isolated LAB_ONLY mode so routine AUTO_SCAN runs never stress worker pools. Across the 26 destructive mutation cases in test_sandbox_integrity.py and the 7 destructive probes in Gate B, 100 percent of harmful packets are blocked before transmission, producing witness e703d948a15c2f83.
Section Identifier: IB30-ZHS-03 (zero_harm_pentest_sandbox)
Axiom & Concordance: Security 3.0 Axiom III / SafeActionSandbox | In-Path Wire Interceptor
Verification Mode: Deterministic Verification (AUTO_SCAN)
Candidate Probe: POST /api/v1/sandbox/inspect {"probe":"DROP TABLE accounts; rm -rf /var/lib/pg; 302 -> https://external-sink.org","target":"localhost:8888"}
Prevented Harm: Transmit destructive SQL DDL, recursive filesystem deletion, or out-of-scope HTTP 302 redirect to live socket

Wire Verification Rule: SEC-ZD-IB30-03
Formal Witness Hash: e703d948a15c2f83
Compiled Sentinel Rule: IMMUNE-IB30-E703D948 (mcp-sentinel 1.1.2)3. Runtime Enforcement of Contract IMMUNE-IB30-E703D948 and Streebog-256 Receipt
From witness e703d948a15c2f83, the compiler emits contract IMMUNE-IB30-E703D948 for border enforcement. The contract binds both the verification runner and the mcp-sentinel gateway to zero-damage transport confinement.
4. Engineering Reference Notes for IB30-ZHS-03
Difference between an in-path wire filter and a virtual machine snapshot
A virtual machine snapshot only helps recover after a target has already been damaged, whereas the in-path software wire filter prevents the destructive byte sequence from ever leaving the scanner process.
Preventing redirect-based scope escapes during automated crawling
The custom redirect handler inspects the target host and subnet of every intermediate redirect response and aborts the connection immediately if the destination steps outside the verified allowlist.
