Step 2 of Felis-nano: a [[auth_source]] array-of-tables (tag + full hasJoined
url, config order = priority) supplies the multiplexer's third-party Yggdrasil
roots; cmd/felis prepends Mojang as the sole code-owned identity anchor and
wires them into API.AuthSources. With no sources configured the endpoint stays
inert (204s), unchanged from step 1.
The config deliberately has no identity/trusted field: Mojang is the only source
whose self-asserted UUIDs are trusted verbatim, so no misconfiguration can
reopen the impersonation hole the per-source UUID rewrite closes. An identity=
key is an unknown key and Load rejects it. Validate adds two fail-fast guards:
unique tags (namespace collision) and a scheme-qualified url (else the source is
silently dead, never validating any login).
setup provisions the always-on login/lobby system services only when these image refs are set; empty means skip-and-say-so (the same fail-loud stance manifests takes), since no official LOOHP/Limbo image exists and a deployment must build its own.
Foundational libraries: deterministic resource naming, the RCON client, the Postgres store with embedded SQL migrations, configuration loading, and container image-build helpers.
