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 Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# Prebuilt-binary spec for cortex.

#
|
|
# Unlike cortex.spec (which builds from source via cargo), this spec
|
|
# wraps a pre-built `cortex` binary produced by an upstream CI job and
|
|
# packages it for rpm.lair.cafe. The %build phase is a no-op.
|
|
#
|
|
# Required defines at rpmbuild time:
|
|
# cortex_version e.g. "0.1.16"
|
|
# cortex_prerelease e.g. "0.1.20260518gitabcdef0" (used as Release)

%description
|
|
Cortex is a Rust reverse-proxy that sits in front of multiple neuron
|
|
inference daemons and presents a unified OpenAI and Anthropic
|
|
compatible API surface.
|
|
|
|
This package wraps a binary built upstream in CI; the source-build
|
|
spec (cortex.spec) remains available for stable releases.
