Adds a star history chart to the README, rendered by the org's reusable workflow
(sportsdataverse/.github#56 — merge that first).

  • .github/workflows/star-history.yml calls the shared workflow daily, on each new star, and on manual dispatch.
  • The chart (light/dark SVG + PNG) is pushed to an orphan star-history branch, never main, so branch protection and README.Rmd re-knits are unaffected.
  • The README embeds it from raw.githubusercontent.com, which also renders on CRAN / PyPI / npm.

Why: since 2026-06-30 GitHub restricts the stargazers API to a repo's own admins/collaborators, which blanked hosted star-history.com embeds; the repo's own GITHUB_TOKEN still qualifies.

After merging: run the "Star history" workflow once (Actions → Star history → Run workflow) so the image exists before the next release.

Summary by Sourcery

Add automated star history tracking and display it in the project README.

New Features:

  • Add a self-updating GitHub star history chart to the README with light and dark theme support.

Enhancements:

  • Embed the chart from the repository’s generated star-history branch for reliable rendering across package and documentation sites.

CI:

  • Run the star history generation workflow daily, when the repository receives a new star, or on manual dispatch.

Documentation:

  • Update the README source and rendered documentation to display the repository’s star history.

Summary by CodeRabbit

  • New Features
    • Added a star history chart beneath the GitHub stars badge in the README, linking to the repository’s stargazers page. The chart is refreshed daily and can also be refreshed on demand or when a watch is started. It adapts to dark-mode preferences, displaying a dark-themed chart when dark mode is enabled and a standard chart otherwise.

Reviewer's Guide

Adds a self-updating star-history chart by calling the organization’s reusable workflow on scheduled, star, and manual triggers, publishing generated light/dark assets to an isolated branch, and embedding them in the README through raw GitHub URLs.

File-Level Changes

Change Details Files
Add an automated workflow that generates and publishes star-history assets to a dedicated branch.
  • Invoke the organization’s reusable workflow on a daily schedule, new-star events, and manual dispatch.
  • Grant content write permission and serialize runs while canceling superseded executions.
  • Keep generated assets isolated on the orphan star-history branch rather than main.
.github/workflows/star-history.yml
Embed the self-updating star-history chart in the README with repository-hosted assets.
  • Use a linked responsive <picture> element with light/dark SVG support and a PNG fallback.
  • Load images from the star-history branch via raw.githubusercontent.com so external package/documentation renderers can display them.
  • Add the corresponding chart content to the README source and rendered README.

The chart cannot be published until the upstream reusable workflow is available, and the README images currently return 404. Merge the dependency first, then run the workflow to publish the chart assets.

**Mutable workflow can write repository**

When the upstream workflow on `main` is changed to perform unauthorized actions, a contributor or attacker who can change `sportsdataverse/.github`'s `main` branch can change the reusable workflow that runs here; each trigger then executes that code with this repository's `contents: write` permission, allowing it to modify repository contents beyond the chart.

Pin the reusable workflow to a reviewed commit SHA and update that pin through review.

Also at `.github/workflows/star-history.yml:11`.
</issue_to_address>

Sourcery assessment

Needs a human reviewer. 1 finding to address first, and the scheduled workflow grants a reusable workflow from the mutable sportsdataverse/.github main branch permission to write repository contents. If that workflow or branch is compromised, it can alter this repository without a code change here; reverting this PR stops future runs but does not undo changes already made.
