Tamper Response Layer

**Description**
Implement a modular tamper detection & response system. Detect physical or software-level tampering and trigger the configured response (e.g. wipe, alert, lockout).

**Initial Ideas**

* **Self-checksumming** of kernel module or memory region
* **Physical tamper switches** (e.g. GPIO pin triggers, chassis intrusion sensors)
* Detect **unexpected code changes**, binary hash mismatches, or unexpected syscall behavior
* **Anti-debugging / integrity checks** (optional, stealth layer)

**Goals**

* Modular detection hooks (plug into existing trigger system)
* Low overhead; avoid noisy or unreliable signals
* Configurable response action per tamper event

**Future Extensions**

* TPM integration for secure measurement
* UEFI secure boot attestation
* Integration with hardware watchdogs
* Logging mechanism for post-mortem analysis (if safe)

The issue describes a modular tamper detection system for a Linux kernel module. Start by examining the existing trigger system in the repository to understand how detection hooks can be integrated. Look for kernel module source files and existing event handling. Determine what constitutes a tamper event and how responses like wipe, alert, or lockout are configured. Testing will require building and loading the kernel module.
