A C++ RAII wrapper around OpenWrt's ubus/blobmsg messaging API. It provides safe resource management for ubus connections, filtered iteration over blob attributes, and clean error handling. This is a reusable pattern for any C++ service that needs to talk to ubus without leaking or manually managing raw C structs.

A self-contained LD_PRELOAD interposition library that intercepts socket, bind, send, and connect calls to force packets onto a specific source IP, device, or firewall mark. It is a clever, non-obvious system-level technique for multi-WAN policy routing and can be extracted for use in other Linux networking projects.

A generic Go package build helper that standardizes configure, build, install, and cache-cleanup steps for cross-compiling Go programs inside the OpenWrt build environment. It encapsulates the tricky GOOS/GOARCH/CC/ldflags setup and is reusable for packaging any Go application for OpenWrt or similar embedded build systems.

A shared shell library for ACME certificate workflows, providing reusable helpers for account/key management, configuration handling, and hook integration. It is one of the cleaner, more modular shell components in the feed and could be lifted into other ACME client projects that need OpenWrt-style shell glue.

A ucode-based mock library that stubs ubus and UCI calls with deterministic fake data, enabling offline unit tests for OpenWrt shell/ucode daemons. It demonstrates a repeatable testing pattern for embedded system services that normally depend on live system state, and can be reused as a template for other OpenWrt package test suites.
