[kachelle]

A new achievement for everyone with a commit in this repository: git blame, "Landed a commit in the /dev/null repo itself. git blame now points at you." It replaces the contributor label from #1198.

Summary by CodeRabbit

• New Features
  • Added the git blame achievement badge, bringing the total number of badges to 16. It unlocks when your GitHub account appears in the repository’s contributor list with at least one commit.
  • The badge’s progress is based on the GitHub account associated with your profile, rather than your GitHub handle. Its status may reflect cached contributor information until that information refreshes.

Walkthrough

The pull request adds a Git blame achievement. It uses a user’s GitHub account ID to find their commit count in the /dev/null contributor list, calculates badge progress, and renders the new badge icon in the achievements dialog and shelf.

Changes: Git blame achievement

Layer / File(s)	Summary
Contributor commit-count lookup app/Queries/ContributorsQuery.php, tests/Unit/Queries/ContributorsQueryTest.php, tests/Pest.php, tests/Feature/Controllers/AboutControllerTest.php	ContributorsQuery returns the commit count for a matching GitHub account ID, or zero when contributor data or a match is unavailable. Tests cover account matching, an HTTP error, and contributor cache setup.
Badge definition and progress app/Enums/Achievement.php, app/Queries/UserAchievementsQuery.php, tests/Unit/Queries/UserAchievementsQueryTest.php, KNOWLEDGE_BASE.md	The new GitBlame achievement has a target of one. UserAchievementsQuery uses contributor commit counts for its progress. Tests and documentation describe the badge and its contributor-list basis.
Badge icon rendering resources/js/components/achievements-dialog.tsx, resources/js/components/achievements-shelf.tsx	Both achievements views map git-commit-horizontal to GitCommitHorizontal.

Merge Risk: Low · up to 3a1dd

Contributor badges can temporarily lock during a GitHub outage, and some profile views or commit submissions may be slow when the cache expires. These bounded risks are suitable for owner awareness before merging.

Security architecture risk: Low · up to 3a1dd

The badge uses GitHub account IDs and does not grant privileges or XP. However, an expired contributor cache makes profile loads and commit submissions wait for GitHub, extending an external dependency into core requests. Existing caching, timeouts, and error handling limit the impact.

Retained concerns

• Medium · reliability · observed: Cold-cache achievement computation now performs synchronous GitHub pagination during profile rendering and web commit submission. The fetch permits up to ten sequential requests, each with a five-second timeout, without single-flight protection. Concurrent misses can duplicate work before caching completes. The mechanism predates this PR on the About page, but the new callers extend its latency and failure-containment effects into core requests.

Security review details

Security Blast Radius

• inferred — The incremental exposure is request latency and duplicated outbound work affecting profile and commit requests that use this cache. Profiles are guest-accessible, but anonymous callers could already trigger the same cache-miss fetch through About at the base revision. No new attacker-selected destination or increased credential authority is established.

Trust Boundaries and Controls

• observed — GitHub contributor data becomes cosmetic badge progress, not an authorization decision or XP award. Web commit submission remains behind authentication, posting restrictions, commit rules, and commit throttling. Contributor parsing retains its existing account-type and field-type checks.

Resilience and Maintainability Implications

• inferred — The cache read, remote fetch, and write are not coordinated across concurrent misses. In-flight readers can duplicate pagination, and a late failure can overwrite a successful result with the failure sentinel. This race predates the PR; new achievement callers increase opportunities to encounter it. Its badge-state effect is non-authoritative, while its request-capacity effect depends on unavailable production concurrency details.

Hardening Proposals

• proposed — Decouple cosmetic achievement reads from synchronous contributor refreshes. An independently refreshed cache with coordinated refresh ownership would contain upstream latency and duplicate work without making badge availability part of commit submission.

Review comments at @app/Queries/ContributorsQuery.php:
- Around line 83-84: Update ContributorsQuery’s refresh/cache flow to retain the
last successful account list independently of the 3,600-second refresh deadline.
Failed refreshes must leave that list available for commits() so contributor
counts and earned git_blame badges persist until a later successful refresh
replaces it.

Review comments at @KNOWLEDGE_BASE.md:
- Line 147: Update the outage description in the git blame row to state that the
badge remains locked only when no contributor list is cached; clarify that a
cached successful list keeps an earned badge unlocked during a GitHub outage.
