Summary

Refs goceleris/celeris#700 (the docs part; celeris's own README is still to do, so this does not close it).

This gives the README the same first screen as the other goceleris repositories: a live badge row, what the site is, how to run it locally, and the stack. It no longer hard-codes stack versions, so the stale "Astro 5" cannot come back. Every factual claim was checked against the repository at fdf27df; the ones it contradicted are corrected.

Changes

  • Badge row: one centered row under the cover, grouped status → quality → project. The static HTML badges are gone, including "Astro 5" (the site runs Astro 7.3.3 per bun.lock:487) and the static "Bun ≥1.3".
  • Versions are read, not written:
    • The Astro badge is shields.io/github/package-json/dependency-version/goceleris/docs/astro.
    • The Bun badge reads engines.bun from package.json on main through shields.io's dynamic JSON badge.
    • The prose points at package.json and bun.lock instead of naming versions.
  • First screen: a pitch, quick links (Documentation, Benchmark dashboard, Methodology, Run it locally), then What this repository is and Run it locally. The latter now uses bun install --frozen-lockfile, as CONTRIBUTING.md and CI do.
  • Corrected against the repository:
    • The Fonts API is no longer experimental: it is the top-level fonts key (astro.config.mjs:32).
    • "Every page including the dashboard is rendered at build time" was wrong. The dashboard is one client:only="preact" island (src/pages/benchmarks/index.astro:27) that loads its JSON at runtime.
    • env.json holds run provenance: version, arch, date, run, git ref, celeris and loadgen versions, run config and fabric. It does not hold kernel, Go, CPU or compile flags; see any results/*/*/*/env.json.
    • histograms.json.gz is kept for provenance; the site does not read it (scripts/import-run.ts:58).
    • validate fails on summary.json/env.json errors and only warns on timeseries problems. build marks a cell excluded:invalid only when its summary.json is missing, unreadable or invalid (scripts/build-data.ts:125-137).
    • bun run check needs build:data first.
    • SITE_URL is a build-time setting, not a runtime override.
    • The pages list now includes docs/index.
    • sync-benchmarks.yml also has a manual trigger and retries while main catches up.
    • Search indexes the documentation pages only (data-pagefind-body, src/pages/docs/[...slug].astro:106).
    • uPlot is used by the over-time view.
    • test/fixtures/sample-cell is the fixture the tests use.
  • Dropped because they go stale: the list of committed versions (it said v1.5.5 and v1.5.6; the tree now also has v1.5.7 and v1.5.8, and v1.5.5 to v1.5.7 are deactivated) and the doc count.
  • Added a Related projects footer and a Contributing section (CONTRIBUTING.md, SECURITY.md).
  • Kept the ## Content structure heading, because CONTRIBUTING.md:33 links to README.md#content-structure.
  • The README has no benchmark figures, so CodeRabbit's "Benchmark provenance" check has nothing to flag.

Verification

  • Badges and links: a script extracts every markdown link, HTML href and image src from README.md (outside code blocks) and checks each one.
    • Absolute URLs: curl -sSL followed redirects. All answered 200, and every image had an image/* content type.
    • SVG badges: the text they show was read out of the SVG (table above).
    • Relative targets: each exists at the branch head, checked with git ls-tree.
    • In-page anchors: each matches a heading slug.
    • Result: 53 checked, 0 failures.
  • GitHub rendering: gh api markdown -f mode=gfm -f context=goceleris/docs rendered 13 headings and 7 images. There were 0 leaked-markdown findings, and every image has alt text.
  • Repository checks: nothing lints or imports README.md. There is no markdownlint config, no package.json script and no CI step; only CodeRabbit reads it. So bun run validate is unaffected, and CI runs the full install, validate, build, check and test on this PR anyway. bun.lock is untouched.
  • Still to do before merge: check the rendered page in light mode, dark mode and at phone width.

Found while checking (not changed here)

  • results/README.md has the same stale env.json description.
  • It also still says there may be no data yet.
  • It draws run-2/ beside <arch>/, but walk.ts:7 expects <arch>/run-N/.
  • test/fixtures/cell is referenced by nothing.

Test Plan

README-only change: nothing in the build reads README.md, so the build CI job is the check for the steps below.

  • bun install --frozen-lockfile (CI)
  • bun run validate (CI)
  • bun run build (CI)
  • bun run check (CI)
  • bun test (CI)
  • Rendered with GitHub's markdown API; links and badges checked (above)

Review follow-up (CodeRabbit, first review)

The one finding is disputed, with a wording improvement in 9f2c3b8. The thread has a reply and is resolved.

  • The finding: CodeRabbit said mage Publish does not commit under results/, and that the docs repository ingests the cell instead.
  • Why it is refuted:
    • probatorium's mage_publish.go:92-101 writes results/<ver>/<date>/<arch>/{4 files} into the docs checkout, commits and pushes it (or PUTs each file through the contents API), and then fires the pointer dispatch.
    • There is no ingestion step in this repository; sync-benchmarks.yml only verifies and validates.
  • The wording change: the step now names both publish paths, PUBLISH_VIA=git (the default, one commit) and PUBLISH_VIA=contents.

CodeRabbit's re-review reported no actionable comments. After the change, the verification was re-run at 9f2c3b8: 53 links and images checked with 0 failures, and 0 leaked-markdown findings.

…ions read from package.json

Refs goceleris/celeris#700.

- One centered badge row under the cover, grouped status, quality, project:
  CI, goceleris.dev status, Codecov, Astro and Bun versions read live from
  package.json by shields.io, license. Replaces the stale static "Astro 5"
  and "Bun >=1.3" badges.
- Prose no longer hard-codes stack versions; it points at package.json and
  bun.lock.
- Corrected claims the repository contradicts: Astro 7 (not 5), the Fonts
  API is no longer experimental, the dashboard is a client-only island that
  loads its JSON at runtime, env.json holds run provenance (not kernel/Go/
  CPU/compile flags), histograms.json.gz is not read by the site, what the
  validate gate and the lenient build actually reject, SITE_URL is a build
  setting, the docs/index page, sync-benchmarks' manual trigger and retry.
- Dropped the committed-versions list and the doc count, which go stale.
- Related projects footer and Contributing section; keeps the
  "Content structure" heading CONTRIBUTING.md links to.

Linked repositories findings

goceleris/celeris — default branch

  • Its README identifies probatorium as the authoritative benchmark harness and loadgen as the matrix driver, matching the revised related-project descriptions (README.md:408, 458). [::goceleris/celeris::]
  • The documented engine defaults and platform support are explicit: Adaptive on Linux and Std elsewhere (README.md:327–330). Any copied API/default claims in the docs README should remain aligned with these values. [::goceleris/celeris::]

goceleris/probatorium — default main (bf870f5)

  • mage Publish writes the four-cell files (summary.json, histograms.json.gz, timeseries.json.gz, and env.json) and then dispatches a pointer; the docs workflow owns index.json and latest/ (mage_publish.go:89–108). [::goceleris/probatorium::]
  • Publishing supports the default git path and the contents API path via PUBLISH_VIA (mage_publish.go:168–182, 631–634). [::goceleris/probatorium::]
  • Git publishing retries pushes while the docs main branch advances, with six bounded attempts (mage_publish.go:759–777). [::goceleris/probatorium::]

goceleris/loadgen — open PR #84 branch (8de5242)

  • The result contract supports request/error counts, RPS, P50–P99.99 latency, per-second timeseries, and exported HdrHistogram data (README.md:64–65, 390–410). [::goceleris/loadgen::]
  • Rated mode measures from intended dispatch time for coordinated-omission correction (README.md:208–224), matching the benchmark methodology described by the docs.
  • The documented/fallback release version remains v1.4.13 (README.md:417, version.go:15). [::goceleris/loadgen::]

Systems and components

  • observed — README.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

  • observed — Modified behavior in README.md: The introduction now describes the site’s documentation, methodology page and benchmark dashboard, including its client-only Preact island. Local setup uses the Bun version specified by engines.bun in package.json and frozen-lockfile installation; it adds the methodology route and distinguishes committed results/ data used by dev from synthesized .dev-results/ used by demo. The previous Quickstart framing and specific claim about committed versions v1.5.5 and v1.5.6 are removed.
  • observed — Modified behavior in README.md: The scripts table adds descriptions for bun test and bun run validate. Validation now documents failures for invalid summary.json or env.json, status 2 when no cells are examined, and warnings for timeseries.json.gz; it identifies the CI and publish workflows that run the gate. Unlike build, validation also scans versions in DEACTIVATED_VERSIONS; builds warn and exclude cells with missing, unreadable or invalid summary.json while continuing.
  • observed — Modified behavior in README.md: The stack section is renamed and revised to identify package files as version sources, describe the client-only dashboard and its six views, specify the Astro Fonts API configuration key, and point to the content schema file. The canonical URL is documented as deriving from SITE_URL in Astro configuration.
  • observed — Modified behavior in README.md: The document count is removed. The README retains the seven sidebar groups and updates the page listing to include the docs index, article routes and methodology page.

🔀 Multi-repo context goceleris/probatorium, goceleris/loadgen, goceleris/celeris

Linked repositories findings

goceleris/probatorium — default main (bf870f5)

  • The benchmark contract matches the documentation: mage BenchTier uses one pass, and latency_at_slo is derived from merged HdrHistogram P99 values. [::goceleris/probatorium::]
  • Publishing is split across boundaries: mage Publish writes summary.json, timeseries.json.gz, histograms.json.gz, and env.json; the docs repository performs ingestion. The README should avoid implying that probatorium’s publish-results workflow itself writes the dashboard index. [::goceleris/probatorium::]

goceleris/loadgen — open PR #84 branch (8de5242)

  • The documented result contract is confirmed: requests/errors, RPS, P50–P99.99 latency, per-second timeseries, and an exported HdrHistogram. Rated mode measures from intended dispatch time for coordinated-omission correction. [::goceleris/loadgen::]
  • Probatorium’s documented v1.4.13 pin matches loadgen’s fallback release version and the branch’s README examples. [::goceleris/loadgen::]

goceleris/celeris — default checkout

  • Its README independently identifies probatorium as the authoritative cross-framework harness and loadgen as the matrix driver, consistent with the revised project descriptions. [::goceleris/celeris::]

Comment thread README.md Outdated
mage Publish writes the cell into this repository's results/ and pushes it
