A standalone crate providing a thread-safe r2d2 connection pool for ALPM, the low-level Arch package management library. It solves a recurring systems-programming problem—managing concurrent access to a stateful native database—and can be reused by any ALPM-based tool without tight coupling to Aura's command logic.

Implements parallel, recursive dependency resolution for AUR packages using petgraph for topological sorting, cycle detection, and conflict handling. The algorithm is domain-specific to Arch package metadata but the graph-based resolution pattern is directly transferable to other package managers, build systems, or dependency analyzers.

Provides JSON-based package state snapshots with pinning and rollback support. It encodes current package state into a portable, diffable format and could be extracted as a reusable snapshot subsystem for any system that needs reproducible state capture and restoration, not just package management.

A security scanner that parses PKGBUILD shell scripts into a bash AST and detects dangerous commands and patterns. This is a non-obvious static-analysis technique that is isolated enough to be reused or ported to other build-script validation contexts, and it demonstrates more skill than simple regex-based blacklists.
