Chaos engine

hardkas chaos formalizes destructive behavior into deterministic, reproducible campaigns. It uses a seeded LCG PRNG (MINSTD) so every campaign is reproducible from its seed.

LockHell

Injects stale locks, zero-byte TOCTOU locks, concurrent rebuilds.

RotBot

Corrupts JSONL streams with truncated JSON, garbage bytes, schema violations.

DriftHunter

Deletes SQLite, mutates projection inputs, verifies rebuild from artifacts.

HumanChaos

Runs invalid commands and operator mistakes to detect raw stack trace leaks.
