Hmm, possibly: std/unittest.e is [as detailed below] almost but not quite compatible with Phix, which has builtins/unit_test.e instead.
No previous version of Phix has to date shipped with any std/unittest.e, so a quick "get it from" note and/or a `--/**/requires("1.0.2")` would be warranted.
I quickly "fixed" a few issues with clashing TEST_QUIET/SHOW_ALL, removed a few incompatible namespaces, and included builtins\pretty.e instead of std/pretty.e,
(let me know if/when you actually/really need that to be uploaded) however std/unittest.e also defines an incompatible assert() routine which:
a) disagrees with Phix's assert(bool condition, string msg="", object args={}, integer nFrames=1)
b) disagrees with it's own documentation in a way that I just simply cannot understand [ticket merited].
I have got the raindrops test working here, but should future exercises start using assert() that'd kill it.
A final decision as to whether Phix can share with Euphoria is probably left until it is (nearly) complete.
I suppose it would also depend on how easy or difficult it is to fork things and suck any updates over.

I just tried to create a ticket and it failed. I had penned the following:

Parameter name is defined as "a string, the name of the test", but the actual implementation has an else(not sequence name) which...

While you're here, that routine clashes with Phix's assert(bool condition, string msg="", object args={}, integer nFrames=1)
whereby msg=sprintf(msg,args) occurs if needed and nFrames allows errors to be reported in user source code rather than
less helpful builtins/ innards, and assert(true) is silent whereas assert(false) crashes.
To my mind it would be better if test_true() had an optional crash argument, and std/unittest.e users had to call that directly instead.

But going back to the relationship between Phix and OE. Is Phix essentially OpenEuphoria 5.0 or is the divergence total and permanent?

Euphoria is a programming language like Python or Ruby. And much like those languages there are a variety of implementations and derivatives of Euphoria.

OpenEuphoria is the reference implementation of Euphoria, like CPython or Ruby MRI. It is developed by the OpenEuphoria Group (this website and its members) and is based on the original code released by Rob Craig in 2006.

Phix is a dialect of Euphoria, like PyPy or JRuby. It is developed by Pete Lomax and is entirely its own code base at this point.

Given my response above, I'd say if you are building this track for "Euphoria" in general then no, you'll only need to maintain one track.

But if you're focusing on the implementation of "OpenEuphoria" specifically then yes, someone would need to maintain a separate "Phix" track in parallel.

How do the other programming languages I mentioned (Python or Ruby) handle their separate dialects on Exercism?
