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.

Ties an in-game account to a website user and gates reads on ownership.
- schema: shard_account_links (account PK → user_id, char_name, linked_at;
FK users ON DELETE CASCADE) — the site-side mirror of the sidecar's
authoritative link.
- model/shardLinks: upsert/list/ownership-check/getByAccount/unlink.
- player/shard.controller.js:
- POST /player/shard/link — confirm a one-time [link code via
uoLinkClient.confirmLink(code, req.user.id); on link.ok mirror the link and
activity.log it; bad/expired codes → 400, shard down → 503.
- GET /player/shard/accounts — the caller's linked accounts.
- GET /player/shard/roster/:account and /vendors/:account — live round-trips,
ownership-checked against the mirror (403 otherwise), 503 on shard restart.
- player.routes.js: mounted under the existing requireRole('player') gate with
express-validator guards + #swagger annotations; new "Player · Shard" tag and
ShardLinkRequest/ShardLinkResult/ShardLink schemas; spec regenerated.
