Modules

biometric

Biometric authentication for guardrail bypass on macOS.

cache

config

engine

hook

journal

Write journal — tracks recently written files for chaining detection.

model

testing

Structs

ChainedNormalizer

Generic normalizer combinator: applies A then B.

FixedFingerprinter

Fixed fingerprint for testing.

IdentityNormalizer

No-op normalizer — returns input unchanged.

MemCache

Thread-safe in-memory cache.

NullPrefilter

No-op prefilter — nothing is safe, all inputs reach the DFA.

PathNormalizer

Strips absolute path prefixes from inputs:

Traits

CacheStore

Trait for cache storage — abstracts filesystem for testability.

Fingerprinter

Trait for fingerprinting — abstracts input to a hash.

Normalizer

Abstracts input normalization (e.g. stripping path prefixes).

Prefilter

Abstracts the fast-reject prefilter that skips DFA matching for inputs that are definitely safe.
