Configuration is one copy-paste of a wss link URL (Satellites panel or
the paskia satellite CLI), registration is the online 3-way handshake,
scope is adjustable post-registration, the upstream is authoritative for
pushed domains, revocation unlinks both sides.
Registration simplified to a single sync URL: minted in the upstream's
admin UI (Satellite access section of the domain dialog), carrying the
token as userinfo — https://<token>@<auth-host>. Tokens live hashed in
the upstream database, scoped to one rp-id, revocable (drops live
connections). PASKIA_SYNC_TOKENS env is gone.
Data minimization: the sync feed now carries only the scope's sessions
and credentials; the user graph never leaves the upstream. Each session
upsert embeds its master-computed ApiSessionContext (identity display
data + effective permissions for the session's host); user-graph
mutations eagerly re-push affected sessions with fresh contexts, so
revocations land within ~1 RTT. /check and /user-info are proxied to
the upstream (they need the user graph).
Satellite side: replicas keyed by rp-id (no more shared-replica config
conflicts — each remote domain has its own token), the replica refuses
to go live on a ready-message scope mismatch, write-backs are confined
to the token's scope server-side.
Admin dialog: one sync-URL paste field (token split from userinfo,
write-only), uplink verification required to save (reachability, rp-id
match, no nesting, auth host present); a verified uplink takes over the
domain's origins (**.<rp-id> + upstream auth host) and auth host. New
domains adopt the upstream's rp-id and name.
Geographically separate servers may have notable latency between them, making forward/validate request roundtrip unnecessarily slow. This adds a proxy support, where the local server can keep a local copy of a remote domain, while the auth host remains authoritative, but requests can be answered in less than 1ms from local copy.
