The 'Send Reset Email' button in /admin/users previously just
cleared the error banner on success, with no actual 'yes it
worked' feedback. Added a green success banner that mirrors the
error banner's style and auto-dismisses after 6 seconds.
The 'Reset Password' button already shows confirmation in the
modal (temp password to copy, or 'reset email sent' message), so
it doesn't need the banner.
Also tightened the type narrowing in the resetAdminPassword unit
tests — the discriminated union needed a two-step
narrow (`r.success` then `r.method`) before TypeScript would
allow access to variant-specific fields like `tempPassword`.
Both buttons in /admin/users were broken:
- "Send Reset Email" called a no-op stub in
src/actions/admin/users.ts that always returned an error.
- "Reset Password" called resetAdminPassword with a hard-coded
'Tuxedo2026!' password, and the function itself queried a
non-existent `users` table and called a non-existent
`update_user_password` RPC (leftover Supabase-era code).
Rewritten against Neon Auth:
- sendPasswordResetEmail(email) — platform_admin-only action that
calls auth.requestPasswordReset with the configured
NEXT_PUBLIC_SITE_URL + '/reset-password' redirect. Always returns
a clear success/error.
- resetAdminPassword(email) — platform_admin-only action that:
1. Looks up neon_auth.user by email
2. Generates a strong server-side random temp password
3. Tries auth.admin.setUserPassword first (instant credential,
returned to the UI for the platform admin to share)
4. On FORBIDDEN / UNAUTHORIZED / INTERNAL_SERVER_ERROR (the common
case — provision-admin.ts does not promote callers to
role='admin' in Neon Auth), falls back to
auth.requestPasswordReset, which sends a reset link the user
can click to set their own password.
5. On the privileged path, flips admin_users.must_change_password
so the user is forced to pick a real password on next sign-in.
UI updated to handle the new response shape (success-with-temp-
password vs success-with-reset-email-sent) with a fourth modal
state.
Tests: 19 new unit tests across both paths cover authz, input
handling, the privileged happy path, the FORBIDDEN/UNAUTHORIZED/
network-throw fallback, USER_NOT_FOUND surfacing, and the
'both paths fail' case. Full suite: 110/113 (3 pre-existing
getAdminUser failures unchanged).
