 ### Achievement badges and XP
 
-Profiles have **15 achievement badges**. Earned badges appear in a single row, with **+N more** when more have been earned than fit. Hover over the row on desktop or tap it on mobile to toggle a popover with every badge, including locked badges and their progress. Profiles with no earned badges show **View achievements** instead. Select a badge in the popover, or the profile's rank or unlocked count, to open the detailed achievements dialog.

 | **luddite** | Stop following Tom while he still follows you. This deducts **100 XP**; following him again removes the badge and penalty. Accounts Tom has never befriended do not qualify. |
 | **shell shocked** | “Survived the php2shell downtime of Oct '26. Earns 100 XP.” — accounts created before **October 21, 2026 at 14:00 UTC** receive this badge and **100 bonus XP**. Accounts created at or after that moment do not qualify. |
 | **super-saiyan** | Have **9,000 followers or more** on /dev/null. “Y—your follower count. It... it’s over 9000!!!1!” |
+| **git blame** | Have **at least one commit** in the [/dev/null repository](https://github.com/dev-null-sh/dev-null.sh) on GitHub, matched by your GitHub account rather than your handle. “Landed a commit in the /dev/null repo itself. git blame now points at you.” It uses the same contributor list as the About page, cached for an hour, so it can take that hour (and however long GitHub takes to update its counts) to appear after a merge. An earned badge stays while that list is cached; it only locks when the list runs out while GitHub can't be reached, until GitHub answers again. |
 
 Commit counts include replies and quotes. Commit-based badges and XP use non-deleted commits visible to the person viewing the profile, so an author may see progress from pending or rejected commits that other viewers cannot see. Streak badges use the **longest** streak, not the current streak: missing a day does not by itself remove them. Days follow the activity graph's app-timezone grouping, not the user's selected display timezone.
 
-Badges are calculated from current account data, not permanently recorded awards. Removing qualifying activity can reduce progress or lock a badge again; for example, unstarring a commit can remove **stargazer**. **Shell shocked** depends only on when the account was created, so deleting activity does not remove it. When a commit posted on the web unlocks a badge, a toast names it and confetti drops; clicking an unlocked badge drops confetti again. Unlocking a badge does not normally give bonus XP; **shell shocked** contributes **100 XP** once. XP otherwise comes from **10 per commit**, **15 per day in the longest streak**, **5 per star received**, **5 per reply to another developer**, and **2 per star given to another developer**. The **luddite** penalty applies once while the badge is unlocked, not once per unfollow, and total XP cannot fall below zero. A qualifying reply contributes both commit XP and reply XP; pastéis do not add XP.
+Badges are calculated from current account data, not permanently recorded awards. Removing qualifying activity can reduce progress or lock a badge again; for example, unstarring a commit can remove **stargazer**. **Shell shocked** depends only on when the account was created, so deleting activity does not remove it. **Git blame** depends only on GitHub's contributor list, not on anything posted on /dev/null. When a commit posted on the web unlocks a badge, a toast names it and confetti drops; clicking an unlocked badge drops confetti again. Unlocking a badge does not normally give bonus XP; **shell shocked** contributes **100 XP** once. XP otherwise comes from **10 per commit**, **15 per day in the longest streak**, **5 per star received**, **5 per reply to another developer**, and **2 per star given to another developer**.

A qualifying reply contributes both commit XP and reply XP; pastéis do not add XP.
 
 XP also determines your Unix rank: **user** at 0 XP, **daemon** at 50, **operator** at 150, **maintainer** at 400, **wheel** at 1,000, and **root** at 2,500. The achievements dialog's **Ranks** tab shows the levels and progress. Level-up notifications use your public progress, so pending or rejected commits do not trigger them. Each level above the starting rank can notify you only once, even if you lose and regain the XP; jumping ahead does not send a notification for every skipped level.
