A: The HME doctrine assumes that the underlying infrastructure—specifically the host OS, network fabric, and hypervisor operating at Ring -1—is actively compromised. Standard encryption is neutralized during cleartext execution in RAM. To solve this, Vapor Audit implements "Hardware Pinning" (Mandate 9.0). The Master Auditor parses Infrastructure-as-Code (IaC) to strictly mandate the machine_type = "gdccs-g2" parameter, ensuring the workload executes exclusively on AMD EPYC processors equipped with Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP). This ensures memory encryption keys are managed by the on-die Platform Security Processor (PSP) and are cryptographically isolated from the host hypervisor.

A: Teleportation attacks exploit mutable software "Region IDs" that can be spoofed by a compromised control plane during live VM migration. Vapor Audit abandons logical region IDs in favor of "Alibi Routing" (Mandate 7.0). The system uses Kernel Bypass Networking (AF_XDP/DPDK) via raw TCP sockets, executing with NET_ADMIN capabilities to eliminate OS network stack jitter. It measures the Round-Trip Time (RTT) to geographically trusted Alibi Nodes. Using the constant speed of light in fiber optic glass ($c \approx 200,000$ km/s), the system calculates a maximum physical distance constraint. A hard-coded threshold of MAX_LATENCY_MS = 15.0 enforces a strict geodesic radius of approximately 1,500 km. Any measurement exceeding 15.0ms mathematically proves the server has been relocated to an unauthorized jurisdiction, immediately triggering the Fail-Dead protocol.

A: A hypervisor cannot observe a guest without consuming shared physical resources (e.g., L3 cache lines, branch predictors), which creates micro-architectural friction. The Micro-Code Sentry operates as a real-time background daemon (CPUSchedulingPolicy=fifo, Priority=99). It executes a deterministic mathematical fold operation (0..1000).fold(0, |acc, x| acc + x) that fits entirely within the L1 cache. By bracketing this workload with the _rdtsc hardware intrinsic, the system measures the exact CPU cycles elapsed with single-cycle precision. The system calculates a Z-Score against a calibrated baseline (e.g., BASELINE_MEAN = 100.0 cycles, BASELINE_STD_DEV = 5.0). A variance exceeding the SIGMA_THRESHOLD of 3.0 confirms a "Thermodynamic Violation" (Time Dilation or cache eviction), detecting the observer.

A: When a Thermodynamic Violation or location breach occurs, the system must obliterate data before the hypervisor can complete a memory snapshot (the "Snapshot Gap"). Standard memory clearing functions (e.g., memset) are routinely removed by compiler "Dead Store Elimination" (DSE) optimizations. Vapor Audit utilizes ptr::write_volatile(0xFF) to force the memory controller to physically scorch the RAM address with high-entropy noise, defeating the compiler optimization. Immediately following this, the system executes process::abort() (SIGABRT). This bypasses the language runtime's stack unwinding mechanism, preventing the execution of "Drop" traits or destructors that a compromised hypervisor could hook to intercept state data during shutdown.

A: Standard litigation holds rely on vulnerable application-layer logic. Vapor Audit deploys a "Sanitization Interceptor" as a Linux Kernel Module that hooks the filesystem layer via the Linux Security Module (LSM) framework. When a Litigation_Hold boolean is active in the Single Source of Truth (SSOT), the interceptor mechanically blocks all unlink() system calls and SQL DELETE commands before they reach physical storage. It returns an immutable PRESERVATION_LOCK_ACTIVE error code and aggregates blocked deletion attempts via the "Black Swan Interlock" (a 300-second alignment window) to create a forensically verifiable, cryptographically bound audit trail proving "Good Faith" preservation.

A: Semantic liability arises when militaristic or adversarial code terms (e.g., "kill chain," "liability shield") are weaponized during legal discovery to imply malicious intent or a "guilty mind". The Semantic Firewall operates as a mandatory static analysis linter pass during the CI/CD pipeline. It enforces a "Zero-Liability Syntax" by scanning identifiers and documentation, rejecting builds that contain the Banned Lexicon. For example, the system mechanically maps the term "Liability Shield" to the functional term "Preservation Lock," and "Kill Chain" to "Sanitization Sequence," ensuring only neutral, legally defensible syntax reaches production.

A: The Master Key is never persisted to non-volatile storage. The system enforces a (2,2)-threshold Shamir's Secret Sharing scheme. Reconstruction mathematically requires the simultaneous convergence of a Biometric Shard (human authorization transmitted via hardware-isolated USB passthrough) and a Latency Shard (generated dynamically only if the physical speed-of-light geofence is satisfied). These shards are combined using Lagrange polynomial interpolation over the finite field GF(256) directly within CPU registers. The reconstructed key is stored in a Volatile Memory Enclave utilizing a custom allocator (store_in_ram) combined with mlock() to bypass OS page caching, ensuring the key evaporates instantly upon transaction completion or power loss.
