We wrote up the full methodology, architectural post-mortem, and head-to-head 32-core benchmarks against @AIatMeta Prompt-Guard-2 and DeBERTa-v3 in our launch note:

We just launched zn on @ProductHunt a <5ms local gate that stops prompt injection.
Local-first, MCP-native, prompts never leave your box. Evals published, warts and all.

@atbeme Agree. Abstraction tax is real. Minimal harnesses like pi show the model's raw capability. Bloated ones optimize for demo, not latency. The sweet spot is thin orchestration, strong primitives.
@jiya_3063 Short answer: if the .env content ever enters the model context, treat it as leaked. "We don't train" != "we don't retain in history / tool logs".
Btw never let raw .env hit the model. Gate tool outputs or redact before they enter context. Local gate > trusting retention policy.
Full post-mortem: how our training data lied to us, the stop rule that caught it, and every decision behind the rebuild, including what we left out on purpose:

Prompt-injection datasets have a dirty secret: most are template factories that leak into your own eval sets.
Ours did. Benign text scored ABOVE attacks. We caught it with a pre-registered stop rule and rebuilt from scratch: 23,699 rows, 0 leaks.

We just open-sourced @use_zn ❗️
A local-first prompt-injection gate for AI agents. One @rustlang binary. MCP-native.
Rules engine (~50µs) fused with a neural detector at ONE threshold. No LLM in the hot path.
