People who only ever reach private services through the reverse proxy were
invisible to activity accounting. Active users are counted from user.LastLogin
or from the LastSeen of a peer they own, and neither column was written on the
proxy paths — so a person signing in via SSO to a proxied service, or a peer
serving one over the mesh, never showed up in the 24 hour numbers.
Both writes now happen where the proxy already authenticates:
- GenerateSessionToken stamps LastLogin after the session token is signed,
the same column and the same way the dashboard and device login paths do.
- ValidateTunnelPeer stamps the calling peer's LastSeen, the column its owner
activates through.
The policy lives in a new reverseproxy/activity manager rather than in the gRPC
service, matching the module layout the other reverse proxy domains use. It
skips what can never count — service users, embedded proxy peers and WASM
clients — and throttles peer writes to once an hour, well inside the window
accounting asks about and far above the proxy's five minute tunnel cache.
The peer write is a single indexed UPDATE that touches only
peer_status_last_seen. Connected and SessionStartedAt are left alone so the
session-ownership fencing MarkPeerConnectedIfNewerSession relies on is never
disturbed, and the timestamp comes from the database clock rather than the
caller, for the same reason the other status writers take it from there. The
caller's cutoff travels into the statement's WHERE, so concurrent requests for
one peer collapse into a single write instead of each acting on its own stale
read, and a peer that was never seen — NULL last seen, since Status is an
embedded pointer — still records its first activity.
Nothing outside the reverse proxy changes behaviour: the only addition
elsewhere is the RefreshPeerLastSeen store method the manager calls.
