A rules-based engine reads the stacktrace and scores likely culprits using evidence, not guesswork. Only after that diagnosis exists does an LLM turn it into a plain-language explanation — it explains the verdict, it doesn't make one.

Every file gets a SHA-512 identity, so the same mod downloaded from Modrinth or CurseForge is recognized as the same file and never re-fetched. A cache keyed on mtime + size skips redundant I/O entirely.

Works offline first: changes apply optimistically, queue in IndexedDB if you're disconnected, and resolve with last-write-wins once you're back online. Postgres Row-Level Security keeps each user's data isolated at the database level, not just in app logic.

Inspects a mod's bytecode and AST without running it, looking for patterns you'd expect from malware: process spawning, reflection used to dodge checks, raw sockets, native libraries loaded without declaring it.

Before touching a world save, it backs it up, writes to a temp file, validates the result, and only then swaps it in atomically. If anything goes wrong mid-write, the original is still there.
