Loads a small public Qwen3 GGUF on a target neuron host, fires a
deterministic reasoning probe ("What is the capital of France?"),
and asserts the response contains 'Paris'. Used to validate the
candle harness on a real GPU host before the Stage 7 TP work begins,
and as a regression check after future neuron builds.
Defaults to beast.hanzalova.internal + Qwen/Qwen3-1.7B-GGUF + Q4_K_M;
all three are positional args so the same script tests any node /
model combination. Polls /models after triggering the load since
/models/load returns once the materialisation is *queued*, not
finished.

Replaces the string compare of 'git describe --tags' vs the binary's
self-reported --version (which lies about prereleases — every
0.1.16-* RPM reports just "0.1.16") with the dnf-native question of
"is the installed package current against what the repo offers".
Mechanism:
- installed_nvr(): rpm -q --qf '%{version}-%{release}' for the
resident package, falling back to "(not installed)". Capturing rpm's
output through a variable keeps its "package X is not installed"
stdout message out of the result on failure.
- needs_update(): probes rpm -q first (treats absent as "needs work"),
then asks dnf check-update --refresh -q. Other dnf failures collapse
into "needs update" so the subsequent install surfaces a real error
rather than this check swallowing one silently.
- ensure_lair_repo(): probes for /etc/yum.repos.d/lair-cafe-unstable.repo
and adds it with `dnf config-manager addrepo` when missing. The
upstream .repo file ships enabled=0 (unstable channel doesn't
auto-engage on fetch), so we then run `dnf config-manager setopt
lair-cafe-unstable.enabled=1` every run — cheap, idempotent.
- Cortex and neuron install branches now guard `systemctl stop` with
`[ ! -f /usr/lib/systemd/system/...service ] || sudo systemctl stop`
so fresh installs (no unit file yet) don't short-circuit the install
step under set -e.
- dnf output is captured into a variable and only printed (with a
[host] prefix per line) on failure, so success stays quiet and
failures show the actual diagnostic instead of being eaten by
&> /dev/null.

Adds a manually-triggered workflow that builds CUDA-flavoured neuron
binaries and a CPU cortex binary, packages them as Fedora RPMs, signs
them, and rsyncs to the unstable channel at
https://rpm.lair.cafe/fedora/43/x86_64/unstable/. Mirrors the build
pipeline used by grenade/mistralrs-package.
Pipeline:
- prepare: derive {version,short_sha,commit_date} from the checkout;
the prerelease Release stamp "0.1.YYYYMMDDgitSHORTSHA" sorts below
the eventual "1" stable release.
- build-cortex: cargo build --release -p cortex-cli on a rust runner.
- build-neuron: matrix over ada (sm_89) and blackwell (sm_120) on
cuda-13.0 runners; cargo build with features "cuda cudnn flash-attn"
and CUDA_COMPUTE_CAP set per flavour.
- package-{cortex,neuron}: rpmbuild on the rpm runner against the new
prebuilt-binary specs in rpm/.
- publish: import signing key, sign RPMs, rsync to oolon, createrepo_c
--update, then regenerate packages.json for the UI.
New specs are prebuilt-binary variants — they consume the artifact
from the build job rather than running cargo at rpmbuild time. Each
helexa-neuron-{flavour} package Conflicts with the other flavours and
with helexa-neuron (the future source-build stable package) so one
flavour is installed at a time on a given host.
neuron crate gains cudnn and flash-attn feature flags forwarding to
the corresponding candle features, so the CI build command compiles
those kernels into the binary.
sccache is intentionally NOT used in the prerelease jobs — CUDA
compute cap isn't in its cache key, so flavours would mis-hit each
other. Each prerelease build is a clean cargo build.
Required Gitea secrets (already in place for cortex.spec / COPR
workflow):
- RPM_SIGNING_KEY, RPM_SIGNING_KEY_ID
- RSYNC_SSH_KEY
