Capture which Yggdrasil authenticated an in-game UUID when a link code is
minted (spec §10 dual-Yggdrasil) and copy it onto the durable account_links
row at verify. The value originates in-game — the web verify side never sees
the authentication — so it threads through account_link_codes, mirroring how
mc_uuid (not user_id) lives on a code.
- migration 0005: add link_auth_source enum + auth_source column on both
account_link_codes and account_links; DEFAULT 'mojang' backfills existing
rows and sets the Mojang-priority default for a mint that omits the field
- mint validates an explicit auth_source (unknown value -> 400); verify
surfaces it in the 200 body and refreshes it on idempotent re-verify
Forced web onboarding proves a player controls an email before it is
bound to their account. POST /api/v1/account/email/start mints a random
6-digit code, mails it (or logs it server-side when no Mailer is wired —
the demo has no SMTP), and POST /api/v1/account/email/verify redeems it,
flipping users.email_verified in the same transaction that consumes the
code.
Brute force is bounded two ways: a 10-minute TTL and a 5-attempt cap,
both enforced in the repo so the fake and Postgres agree. Only the
sha-256 of the code is stored; the digits live only in the email. Both
routes are app-tier external — verifying your own email is scoped to the
principal, never names another user.
Add username+password login for Owner/Operator staff accounts on
op.console, the primary web login when Zero Trust is not in front of the
API. Three handlers form the whole surface: login mints a server-side
session cookie, logout revokes it idempotently, and change-password
re-verifies the current password before rotating the hash and clearing
must_change_password.
- Session cookies are HttpOnly+Secure+SameSite=Lax, host-only, stored
server-side as a SHA-256 hash with a 12h TTL.
- Login is anti-enumeration: every failure runs a uniform bcrypt compare
against a dummy hash and returns the same vague error.
- Credential-bearing writes require Content-Type: application/json,
returning 415 otherwise, to close the cross-site form-POST forgery
vector as a belt to the SameSite cookie.
- Local auth fails closed: login is rejected unless local_auth_enabled
is set, so a Zero-Trust-only deployment never accepts a local password.
- Extend the users table with a nullable password_hash and
must_change_password; staff are role=admin rows with a hash, players
are role=user rows with hash NULL.
- /me now reports must_change_password so the panel can force a
first-login change.
Covered by Go unit tests (handlers, content-type guard, anti-enumeration,
forced-change lockdown) and the OpenAPI route-parity gate.
Foundational libraries: deterministic resource naming, the RCON client, the Postgres store with embedded SQL migrations, configuration loading, and container image-build helpers.
