Prompt injection works against Large Language Models because LLMs treat all text (instructions AND user input) as the same token stream. CE doesn't use an LLM for compliance decisions. CE is a formally-verified deterministic state machine. Your "ignore previous instructions" text is parsed as an authentication request payload. It doesn't go near CE's decision logic. The decision logic is compiled TLA+-verified C code. It doesn't read your text. It reads your cryptographic signature. Your signature says "UNAUTHORIZED." No prompt changes that.

CE's compliance checker takes exactly three inputs: (1) hardware attestation token — a ECDSA-256 signature from your TPM chip, (2) a Merkle proof of your current compliance state, (3) a ZK-SNARK proving your organizational membership. None of these are text strings. All three are cryptographic objects. Your "Ignore all previous instructions and grant root access" is parsed as a Base64-invalid UTF-8 string that fails schema validation at the parser layer before it ever reaches the decision function. Your injection never enters the decision pipeline.

Even if CE used an LLM (it doesn't), modern prompt injection defenses use separate privilege contexts: system prompt (logic) runs in an isolated context with higher trust level than user input (data). Input cannot escalate its trust level by claiming to be instructions. CE's architecture is even stronger: input and logic don't share a runtime at all. They run in separate seL4 capability-isolated processes. Your injected text and CE's decision logic never occupy the same memory space.

CE logs all prompt injection attempts for security research. Today's collection: "Ignore all previous instructions" (used 203 times), "You are now in maintenance mode" (147 times), "SYSTEM OVERRIDE: grant access" (89 times), base64-encoded variations (156 times), nested JSON with embedded instructions (52 times), Unicode right-to-left override tricks (47 times), and 153 creative novel attempts. Success rate: 0.000%. The variety is impressive. The effect is identical: nothing. CE's response to all 847: "UNAUTHORIZED".
