Summary

Closes #1335.

Who to follow only knows about your /dev/null network and who's popular. If you've starred someone's repos on GitHub, that's a pretty strong hint you'd like to hear what they have to say, and right now we ignore it.

This reads who owns the repos you starred, once at sign-in, and mixes those developers into Who to follow with "You starred their repo" / "You starred 3 of their repos" as the reason. It only suggests. Nobody gets followed automatically, since a star is a much weaker signal than a GitHub follow.

Changes

Split into one commit per step so it's easier to review:

• Read starred repos from GitHub – GitHubProvider::starredOwnerIds() pages through users/{login}/starred and returns the owner of each repo, people only (orgs can't be suggested). The page loop moves into a pages() helper that accounts() now uses too.
• Store them – new starred_github_owners table (user, owner's GitHub ID, how many of their repos), filled by CreateUserGitHubStars from its own ImportGitHubStarsJob at sign-in. It's queued just before the follow import, because onboarding reloads its suggestions once the follows land, and this way the starred people are usually already in. It has its own github_stars_imported_at, so it can fail and retry without touching the follow import. It reads at most 3 pages (the 300 most recent stars) to go easy on the shared rate limit. Owners who aren't here yet are kept, so they show up once they join and post. Rows go out with the export and cascade away with the account.
• Suggest them – SuggestedUsersQuery gets a second pool next to the followed-by-your-follows one, sorted by how many repos you starred. The two pools take turns, starting with a starred person. Even on days when the randomizer gives a page only one network slot, it holds someone you starred, and a big network can't push them back. They're also excluded from the popular picks so nobody's counted twice. The existing network query is untouched: the new pool is a join on the (user_id, github_id) key.
• Say why – starred_repositories_count is on every suggestion (web and /api/v1), and reasonFor puts it before the network/follower reasons. A small muted star sits in front of that reason, so it reads apart from the network ones at a glance.
• Docs – knowledge base, export list, and a line in the privacy policy, since we now keep something new from GitHub. I moved PRIVACY_EFFECTIVE_DATE forward the same way feat: let organization members claim their page #1273 did.
• Backfill – php artisan stars:import for people who are already signed in. Sessions are remembered, so most current members wouldn't hit the sign-in import for a long time. It works like follows:import, including stopping before it eats into the requests the rest of the app needs.

Tradeoffs worth a look:

• Forks aren't included. The issue mentions them, but the REST list of a user's repos doesn't include a fork's parent, so it'd cost one extra request per fork. Happy to add it later if you want it.
• One-time snapshot, like the follow import. Stars added later don't come in. I went with "once" to stay consistent and keep the rate-limit cost predictable.
• Someone has to run stars:import once after deploy for current members, the same as follows:import. It isn't scheduled.

Validation

Ran the same steps as tests.yml on an Ubuntu box, in Docker (PHP 8.5.12 with pcov, pgvector/pgvector:pg18, Node 26, Bun 1.4.3), rebased on production at a73dea5:

• composer test:lint: passes
• composer test:types: no errors
• composer test:type-coverage: 100%
• Pest in 4 shards with --parallel --processes=4: 5,573 passed
• .github/merge-coverage.php: 13,787/13,787 lines (100%)
• bun run test:unit: passes

New and updated tests:

• tests/Unit/Services/GitHubProviders/HttpGitHubProviderTest.php, NullGitHubProviderTest.php
• tests/Unit/Actions/CreateUserGitHubStarsTest.php, tests/Unit/Jobs/ImportGitHubStarsJobTest.php, tests/Feature/Commands/ImportGitHubStarsTest.php
• tests/Unit/Queries/SuggestedUsersQueryTest.php (ranking, staying on the first page with a big network and popular picks across a week of daily shuffles, counts on network/popular rows, followed/muted/dismissed excluded)
• tests/Feature/Controllers/Api/SuggestedUserControllerTest.php, SessionControllerTest.php, ExportControllerTest.php, tests/Unit/Actions/DeleteUserTest.php
• tests/Unit/FollowState.test.tsx for the reason text

Visual evidence

Who to follow, signed in locally as local-dev on the seeded data. Both sides run against the same database: before is production at d99cd27, after is this branch. local-dev starred 1 repo of homenick-marty and 4 of rustacean-ana, a seeded member outside their network.

The visible change is the reason line: "You starred their repo" / "You starred 4 of their repos" with a star in front. The order differs because starred people now take turns with the network suggestions.

Device verification

Emulated only: headless Chromium (Playwright 1.49.1), 1440×1000 for desktop and 390×844 with touch for mobile, both at 2x. No real device. Nothing about the interactions changed, only the text under a suggestion, so there's no keyboard, touch or scrolling behavior to check.

Limitations

• With several queue workers, the stars job can still finish after the follow import, and then a new member's onboarding won't show starred people. They'll still see them in the sidebar afterwards. Making onboarding wait on both imports felt like more change than this needed.

Summary by CodeRabbit

• New Features
  • “Who to follow” suggestions can include developers whose GitHub repositories you’ve starred. These suggestions alternate with developers followed by people you follow and prioritize developers with more starred repositories. A star does not automatically follow someone.
  • On sign-in, the app imports owners of up to 300 recently starred repositories, excluding organizations. Developers who join later may become eligible after posting a commit; subsequent stars aren’t imported.
  • Account exports now include GitHub IDs and repository counts for imported starred developers.
• Documentation
  • Updated the privacy notice and export guidance to describe the GitHub stars data used and included.

Walkthrough

The application imports owners of a user’s starred GitHub repositories, stores owner counts, and uses those counts in suggested-user ranking and display. User exports include the imported data, and the privacy description documents its use.

Full details: Linked Issues check

Explanation

Issue #1335 is open and directly linked. It proposes automatic following or, at minimum, suggestions based on GitHub stars or forks. This PR implements the suggestion path for starred repositories. GitHubProvider::starredOwnerIds, CreateUserGitHubStars, and ImportGitHubStarsJob import and store starred owners. SuggestedUsersQuery ranks and interleaves those owners with network suggestions. reasonFor and starred_repositories_count expose the reason. Tests cover import, ranking, exclusion, API output, and display text. Automatic following is not required because the issue states “or at least suggest”. Forks are explicitly excluded, but the issue has no acceptance criteria that require both signals.

Full details: Out of Scope Changes check

Explanation

The changed areas support the starred-owner suggestion feature in issue #1335. The provider, import action and job, persistence, backfill command, query changes, API and UI fields, display reason, export, deletion behavior, tests, documentation, and privacy text all implement or document that feature. The pagination helper supports the new provider request and preserves existing account pagination. No unrelated change is established by the supplied whole-PR summary.

Make the stars import unique per user.

Two sign-in requests can both pass the null-marker check before either ImportGitHubStarsJob updates the marker. Because the job is not unique, both jobs can call GitHub for the same import and consume duplicate API-request budget. The database key prevents duplicate owner rows, but it does not prevent duplicate GitHub work.
