Reuse the outstanding auth_ticket instead of minting a fresh one on every
/client load, so reloading the page or opening a second tab no longer
invalidates a game session that is still connecting. New tickets are minted
with a guard against the previously-read value so concurrent launches
converge on the same ticket.
Revoke the auth_ticket when signing out (toolbar, header and sign-out
everywhere) so a leaked ticket can no longer be replayed against the
emulator, and prevent SSO leakage via referral by setting no-referrer on the
client iframe. Strip all whitespace from the ticket prefix and build the
launch URL through a tested helper that handles query strings, existing sso
params and URL fragments correctly.
Pure, unit-tested primitives the AtomCMS->Next.js login must reproduce exactly
(verified now with round-trip + known vectors; full end-to-end check deferred
until a real DB + APP_KEY + live emulator are available):
- password.ts: argon2id (m=65536,t=4,p=1 via hash-wasm) + bcrypt ($2y$ accepted)
verify, and the md5->argon2id on-login upgrade gated by convert_passwords
(mirrors RedirectIfTwoFactorAuthenticatable).
- sso-ticket.ts: '{hotel_name without spaces}-{uuidv4}' written to auth_ticket +
ip_current (mirrors User::ssoTicket()).
- laravel-encrypter.ts: AES-256-CBC + HMAC-SHA256 payload compatible with
Laravel encrypt()/encryptString (for existing 2FA secrets) incl. PHP string
(de)serialization.
- totp.ts: otplib Google2FA-compatible TOTP verify (SHA1/6/30).
Libs: hash-wasm + bcryptjs + otplib (pure JS/WASM, no native build). 28 tests.
