Fixes 31 of 32 confirmed findings from the adversarially-verified ultracode audit of the auth-ui rebuild; #16 is partially fixed with a documented residual. All changes typecheck clean and pass the mirrored cypress component specs. See docs/AUDIT-FINDINGS.md for the full per-finding detail and status. Highlights by subsystem: - session/device: device-authorization grants no longer auto-complete from the forgeable GET /signed-in; they route to the CSRF-protected /device/authorize consent screen (explicit Approve showing app + scope). (#10) - rate-limit: limiters mount on '*' and self-guard on a normalized (lowercased, .data-stripped) path, closing the case-variant and single-fetch bypasses. (#1, #11) - verify: email-code resend is gated on server-verified session ownership and never 500s / enumerates; requestId validated + encoded into the /authorize hand-back. (#9, #25, #30) - signup: registration policy (allowRegister/allowPassword/passkeysType) enforced in the actions; duplicate-email responses emit a Set-Cookie (presence oracle closed, content/size residual documented — #16); fingerprintId used instead of the MaxMind token; requestId resumed on email-link complete. (#3, #4, #14, #16, #17) - sso: guarded getSession/startIdpIntent (graceful branded errors, not 500s); LDAP reauth cookie cleared; ProviderError on sign-in mapped to the branded page; deviceTrackingToken threaded on auto-link. (#2, #5, #6, #13, #19, #20, #21) - providers/mappers: U2F factor derived from the webAuthN proto factor (fixes the U2F login loop); failedAttempts extracted with the proper schema; forceMfaLocalOnly kept distinct from forceMfa. (#0, #7, #22) - session cookie: dual-format (ISO/epoch) timestamp parsing in the eviction pre-pass so the 2KB budget is respected. (#8) - webauthn: real browsers without WebAuthn see the unsupported message instead of submitting the Cypress fake credential. (#27) - fraud: MaxMind token falls back to the cookie when it lands after the poll budget; default-org cache keyed per service URL. (#28, #29) - audit logging: raw loginName replaced with hashActor across OTP/webauthn/password reset events. (#23, #24, #26) - setup: safeParse on tampered skip params; TOTP register guarded. (#12, #31) Verification (2026-07-04): the 12 findings applied in the prior batch were independently re-verified (verifier + adversary per finding). 9 closed cleanly; #10 (device-auth) was incomplete and #30 (resend test) was a regression — both re-fixed here; #16 (signup enumeration) is partial, with the residual documented and full closure (sessions-cookie encryption) deferred by owner decision.

When users try to log in or register using the GitHub IdP, the following error appears on the front page:
The root of the problem is related to the
auth-uinot being able to map thegivenName,familyName, andemail addressprovided by GitHub.This PR introduces a new way of populating the
givenNameandfamilyNamefields from GitHub and also adds support for fetching the user’semail addresswhen it is private on GitHub.Fetching the primary email address is important, as it is used by the notification system.
