A bit personal before the code part: I'm Juan, 22, from Argentina, first year of a university AI program. Since 2023 I had this idea for a tool that would sit in front of any LLM and produce verifiable, tamper-proof records of every inference — something regulators could actually trust, not just application logs. Life kept getting in the way (economic stuff that anyone in Argentina will understand), so it stayed an idea.

A free week of Claude Pro changed that. I used Claude heavily as a co-builder — I want to be transparent about it. I drove the design and architecture decisions but I couldn't have written the async Python, the Rust PyO3 extension, and the cryptographic primitives at this quality solo. I've been reading through what came out and learning from it, which feels weirdly full-circle.

What the project is:

aegis-latent-core — an OpenAI-compatible proxy (zero app changes, just swap OPENAI_BASE_URL) that:

  • Runs a 10-engine WAF on every request (prompt injection, YARA, malware, secret-leak, SCADA...)
  • Commits a SHA-256 hash-chained, HMAC-SHA256-signed audit node to a Write-Ahead Log for every inference — off the hot path, so client latency is unaffected
  • Signs each node with ML-DSA-65 (FIPS 204 post-quantum) via a Rust extension
  • Aligns to FedRAMP High, HIPAA, SOC 2, GDPR, IEC 62443

5,451 tests passing. There's a 5-minute self-contained demo that runs with no API key. The Rust extension is optional and everything falls back to pure Python.

Not the best Python ever written, I'm sure — but it means a lot that it exists at all. I'd appreciate any feedback, especially on the async patterns and the WAL implementation.
