Package hallibtest lets a test binary link the HAL implementation with a single blank import.

Package halnettest provides HAL signal/net/link primitives for tests.

Package rtapialloc is a thin cgo wrapper around the RT-safe allocator (rtapi_calloc / rtapi_free in uspace_rtapi_lib.c) for use in tests.

Package testrt runs the halscope RT state-machine unit suite (test_halscope_rt.c) under `go test`.

Package halstream implements the shared wire framing for the HAL streaming WebSocket transport: halsampler consumes it (decode), halstreamer produces it (encode).

Package lineedit implements the interactive line editing that halcmd's prompt needs: cursor movement, emacs-style editing keys, command history and TAB completion.

Package programfilter runs the [FILTER] converter that turns a source file (an image, a DXF, a script) into the G-code the interpreter executes.

Package tptest exposes trajectory-planner math to Go tests.
