Adds automated, longitudinal performance tracking across neuron builds,
replacing manual script/bench.py runs and hand edits to benchmarks.md.
neuron build metadata + GET /version:
- cortex-core: shared BuildInfo type (build_info.rs).
- neuron build.rs captures git SHA (preferring injected HELEXA_BUILD_SHA,
else git, else "unknown"), dirty flag, build timestamp, rustc version,
profile, target, enabled cargo features, and best-effort candle-core
version from Cargo.lock.
- New GET /version endpoint (version.rs) + clap --version long form.
- SHA injected in CI (build-neuron step) and helexa-neuron.spec
(%{?helexa_commit}) so tarball RPMs report the real SHA. /version is
now the canonical "which build is live" probe.
helexa-bench crate:
- Continuous daemon: hits each neuron directly on :13131, exercises each
warm (status==loaded) model, records every run into a SQLite
system-of-record stamped with the neuron's full BuildInfo.
- Version-aware: skips any (target, build SHA, model, scenario) cell
already at samples_per_version, so a steady fleet costs only cheap
/version + /models polls until a new SHA ships.
- Extensible Scenario trait; phase-1 chat-latency family ported verbatim
from bench.py (synthetic 128/4096-tok prompts, /no_think, streamed
TTFT + decode-window tok/s). `report` regenerates the benchmarks table.
- kind="openai" comparison targets scaffolded, not yet wired.
Packaging: data/helexa-bench.service (+ sysusers), prebuilt-binary RPM
spec (outbound-only, no firewalld), and build/package/publish wiring in
build-prerelease.yml with change detection.
Tests: cortex-core BuildInfo round-trip, neuron GET /version integration,
helexa-bench unit (prompt/SSE/config/store) + end-to-end sweep
(record -> skip -> resume on new SHA). Docs updated (benchmarks.md,
CLAUDE.md addendum).

%description
|
|
Neuron is a per-node daemon for cortex inference clusters. It discovers
|
|
local GPU hardware via nvidia-smi, runs in-process inference via
|
|
huggingface/candle, and exposes an HTTP API for model lifecycle
|
|
management (load, unload, list, inference endpoint).
