Part A — helexa-bench read API:
- [api] config (enabled, listen :13132); WAL on the store so API reads
never block the sweep writer.
- store read methods: summary, series (chronological per-build medians),
runs (filtered), dimensions, run_count.
- api.rs: axum /api/health|dimensions|summary|series|runs, permissive
CORS (UI is a separate origin). The `run` daemon binds the API
alongside the sweep; new `serve` subcommand serves API-only.
- listener plumbing (bench gains a port): data/helexa-bench-firewalld.xml,
spec install, deploy-bench /api/health probe + firewalld step, sudoers
firewall-cmd grants, [api] in example + bob.toml.
- 5 API tests + serve smoke.
Part B — bench/ Vite + React-SWC-TS app (router, react-bootstrap,
recharts): Overview (summary table), Trends (decode tok/s & TTFT across
build SHAs), Runs (filterable explorer). Typed API client with
VITE_API_BASE + dev proxy to bob. npm build/typecheck clean. Hosted
separately from the API (per design); .gitignore excludes node_modules/dist.
