Weekly XP chart on Settings → Usage always renders zero-height bars (reads detail.xp, which no writer ever sets)

[namann5]

What happened?

The "Weekly XP" chart on the Settings → Usage page (src/app/(app)/settings/usage/page.tsx) always renders zero-height bars for every week, even for users with recent XP activity.

The chart is fed by getWeeklyXp, which sums the xp key from each activity row's detail column:

// usage/page.tsx:126
weeks[key] = (weeks[key] || 0) + Number(e.detail?.xp ?? 0);

But no code path in the repo ever writes a detail.xp field. I grepped every activity_log insert site — the actual keys written are:

• pr_merged → detail: { recId, repo, prNumber, xpAwarded } (process-pr-event.ts:453)
• claim → detail: { issueId } / { recId } (issues.ts:376, recommendations.ts:172)
• help_dispatch → detail: { helpRequestId, fromUserId } (help-dispatch.ts:91)
• xp_tripwire → detail: { threshold, priorTodayTotal, triggeringDelta, source, refId } (events.ts:126-133)
• claim_reset_stale / claim_warning_stale → detail: { recId, ... } (maintenance.ts:390, 423)

So e.detail?.xp is always undefined, Number(undefined ?? 0) is always 0, max in XpChart stays at the 1 fallback, and every bar renders 0px tall. The two stat cards ("XP today" / "XP this week") are correct — only the chart is dead.

Steps to Reproduce

1. Sign in and earn XP (merge a PR, claim an issue, get mentor-verified, trip the daily cap).
2. Navigate to Settings → Usage (/settings/usage).
3. Observe the weekly XP bar chart: all 12 bars are flat/empty despite real activity entries and nonzero "XP this week".

Expected Behavior

The chart should sum the actual XP-bearing fields per event kind (e.g. xpAwarded for pr_merged, triggeringDelta for tripwires, the level-up delta for xp audit events), or the writers should store a normalized xp amount. Bars should reflect real weekly XP.

Where does this occur?
