platform_admins D1 table (migration 0018), email PK. Seeded with jixjansen@gmail.com + devonthediamond@gmail.com.

If you’re on the list, the ADMIN entry appears in the hamburger drawer.

Three sections:

1. Mint a school admin invite — optional name / email / country hints. Returns a 6-character single-use code. Click-to-copy.
2. Pending invites — every unredeemed code. Re-send to recipients, audit floating codes.
3. Registered schools — every school that’s redeemed an invite. Shows school code + created date + disable/re-enable.

• Sets disabled_at on the row.
• Members keep their accounts but lose school dashboard access.
• Reversible — tap re-enable.

No UI yet — manual SQL via wrangler:

cd worker
pnpm exec wrangler d1 execute dartboardmaths-db --remote \
  --command="INSERT INTO platform_admins (email) VALUES \
  ('new@example.com');"

Emails must be lowercase (Better Auth normalises).

Every admin action logs structured JSON via lib/log.ts:

• admin.invite_minted
• admin.school_disabled
• admin.school_enabled
• school.created (when an invite is redeemed)

Search the CF dashboard with event:admin.* to audit.

• Don’t drop columns. Schemas are additive — destructive migrations break running deploys.
• Don’t hand-craft codes with 0/O/1/I/L glyphs. The generator excludes them.
• Don’t SQL-delete a school. Orphans every class / assignment / message. Use disable.
