- _remote_headers and /check used struct convenience properties that
read the global database; they now use the SessionContext / the handed
store (also fixes Remote-Credential carrying a struct repr instead of
the UUID).
- Replica availability: TTL clock starts at disconnect, not at last
message or failed reconnect; tight WS keepalive for prompt dead-peer
detection.
- Proxy preserves repeated Set-Cookie via raw headers; sync endpoint
does its own accept (wsutil decorator pre-accepts) and bypasses host
dispatch (server-to-server; satellite may use an out-of-domain
address).
- Admin-credential bootstrap warning skips remote domains.
Verified live with two instances (remote :4501, satellite :4402):
replica snapshot + events, 204 forward with Remote-* in <1ms, validate
write-behind landing on the remote, proxied logout with instant local
eviction, 503 after cache_ttl of disconnect, resync after remote
restart.
