Phase 5: the account-provisioning backend — link-only stays, plus hybrid
self-signup, an admin email-invite tool, and site-side unlink.
- uoLinkClient.createAccount / unlinkAccount (v2). Password is forwarded to the
shard (hashed there) and never stored/logged; the end-user browser IP is passed
for the shard's per-IP cap; actor is stamped server-side.
- Hybrid signup: POST /player/shard/account provisions a game account (its own
username + password) for the signed-in user and mirrors the link locally. Gated
by the new game_account_signup setting AND the shard's own mode (mapped 403/409/
429/400/503). Serves both self-serve signup and the invite-accept game step.
- Email invites: user_invites table (sha256 token hash, single-use, expiring);
invites model + admin CRUD (POST/GET/DELETE /admin/invites, admin-only) +
mailer.sendInvite (falls back to returning the accept link if email is off);
public token-gated accept (GET /auth/invite/:token, POST .../accept) creates the
user at the invite's preset role and logs them in, bypassing the registration
gate. Accept is race-safe (atomic single-use; rolls back the user if it loses).
- Admin unlink: DELETE /admin/users/:id/shard/link/:account (admin-only) + local
mirror drop; account.unlinked ingest reconciles the mirror when a player runs
[unlink in game. account.audit / account.unlinked are logged (admin channel
only — never on the public SSE allowlist).
Tests: invites model (hashing, single-use, expiry, revoke) + account.* ingest
reconcile/visibility. Full suite 193/193; swagger regenerated.

Retire env-var SMTP basic-auth and send the contact form through Gmail over
OAuth2 (SMTP XOAUTH2), configured in Admin -> Settings -> Email via an in-app
"Connect Gmail" consent flow. Reuses the existing google SSO OAuth client; the
captured refresh token is stored AES-GCM-encrypted (write-only over the API,
never returned), mirroring the auth-provider and Discord-bot secret patterns.
- schema: new email_config singleton table (mirrors bot_config)
- model: emailConfig.{db,model} with encrypted refresh token + getSafe/getWithSecret
- mailer: nodemailer OAuth2 transport (client id/secret from the google provider
row), contact recipient = contact_email setting, mailto: fallback preserved,
plus sendTest()
- routes/controller: /admin/email config, connect start+callback (ssoState CSRF
+ PKCE), test, disconnect
- client: EmailDelivery section on the Settings page + api methods; Settings copy
now spells out that contact_email is the delivery recipient
- docs/env: drop SMTP_*/CONTACT_TO from env examples; update README/BACKEND_DESIGN
- tests: emailConfig.model + mailer suites (8 new; full suite 142 pass)
