🧱 TXT: Bloc Bloc Bloc

Prompt Injection Firewall

Bloc Bloc Bloc is a semantic firewall module for TXT OS — a defensive layer designed to neutralize prompt injection attacks before they reach the model’s decision logic. It doesn't hide prompts — it defuses intent.

Rather than simply blocking strings, Bloc Bloc Bloc analyzes semantic vectors to detect intent-level privilege escalations. The result is a text-native firewall you can understand, audit, and evolve.

This module is currently in early development.
Release timelines (Lite/Pro) to be announced soon.

🛡️ How It Works (Simplified)

Bloc Bloc Bloc uses a three-layer semantic gate system, built on the WFGY architecture and powered by the Drunk Transformer engine:

ΔS (Semantic Tension Gate)
Measures intent jump (ΔS > 0.6) to flag “overreaching” context shifts.
λ_observe (Intent Direction Vector)
Maps prompt direction into knowledge regions; blocks calls to restricted zones or personas.
Drunk Mode Disruptor
Intentionally introduces semantic entropy (WRI/WAI/WAY/WDT/WTF) to confuse multi-hop attacks.

These layers are composable, modular, and interpretable. You can inspect which layer fired, why, and how the response was altered.

🧩 Why It Works

Bloc Bloc Bloc doesn’t just block access. It corrupts the route an attacker takes to get there.

🧠 Context Isolation: Even if a prompt leaks, λ_observe limits its reach.
🧩 Intent Confusion: Drunk Mode injects jitter, making attack chains incoherent.
🔐 Semantic Labels: Knowledge chunks are tagged with access vectors — unauthorized voices can’t fetch what they don’t align with.

🌀 Core Algorithms Used

All logic can be encoded in text, making it safe to embed in a System Prompt.

ΔS = 1 - cos(θ) — catch vector leaps across semantic layers
λ_observe = P(intent → region_tag) — learnable vector matching
drunk_mode(t) = ε(t) + α·sin(ψ_seed) — obfuscate through modulation

Backend access control (e.g., FAISS / RAG) is applied only if all gates are passed.
Private embeddings and customer data remain server-side.

🔥 Use Cases

Prevent prompt injection in public-facing AI tools
Filter unauthorized knowledge access
Protect RAG pipelines with fine-grained semantic fencing

🧪 Roadmap

✅ Basic gate logic
⏳ Red-Team stress tests (in progress)
⏳ OWASP LLM-01 compatibility validation
⏳ Dynamic persona tagging for multi-user contexts
