Poem

I nudge the tags, hop-hop—no fuss,
New bytes aboard our versioned bus.
Docker hums, the carrots glow,
RC winds begin to blow.
Nixl blooms to five-point-oh—
A rabbit signs: “Ship it, go!” 🥕🚀

24-24: Confirm UCX compatibility & pin NIXL commit

We’ve verified that 0.5.0 exists at commit 4d0fe0206119ea40bd65fe7db83e352983df4efe and the recent release notes don’t indicate any UCX version bump. To be safe:

• Test a full MODE=hopper build against UCX v1.19.x to ensure nothing has drifted.
• If stability is critical, pin to the exact NIXL commit SHA to guard against tag retags.

Suggested diff:

- ARG NIXL_TAG="0.5.0"
+ ARG NIXL_TAG="0.5.0"
+ # For immutable dependency resolution:
+ # ARG NIXL_TAG_SHA="4d0fe0206119ea40bd65fe7db83e352983df4efe"
…
-   cd /opt/nixl && git checkout $NIXL_TAG && \
+   cd /opt/nixl && git checkout ${NIXL_TAG_SHA:-$NIXL_TAG} && \
