Mirrors the REST-login change in f17c46c on the registration insert path.
A successful POST /api/auth/register does not by itself imply a live
WebSocket — the client may never connect (transient network, mobile
background, error path between the 201 and /ws), leaving a permanently
stuck-online row that no disconnect timer can clean up. The schema
default 'offline' is correct; ws/handler.ts flips it to 'online' on real
WS auth.
The federated-stub upgrade path in the same handler is unaffected: it
only updates passwordHash/username/homeUserId/displayName/avatarColor,
leaving the stub's pre-existing 'offline' status (set when the stub was
created via replication) untouched.
Updates docs/systems/auth.md step 7 to reflect the new behavior.
users.status was only flipped back to offline by the WebSocket disconnect
path (5s grace timer in ConnectionManager). Process exits (deploy/crash/OOM)
lose those in-memory timers, freezing any non-offline row at its last value
and making the user appear permanently online to friends and space co-members.
Confirmed in production on the Pi instance: a user appeared online for ~3
days with no live socket.
Add resetStalePresenceOnBoot() in utils/presenceBoot.ts and call it from
index.ts after getDb()/seedDatabase() and before WebSocket route registration.
The reset is federation-safe: it only updates rows where home_instance IS
NULL (replicated stubs are projections of remote presence and must not be
stomped) and is_deleted = 0 (tombstoned users are excluded from broadcasts).
Also remove the redundant status='online' write from POST /api/auth/login.
A successful REST login does not imply a live socket; the WS auth handshake
is the single source of truth. Login alone could otherwise produce the same
stuck-online row when a client logs in and never establishes a WS.
Tests cover: locally-homed online/idle/dnd reset, replicated rows untouched,
tombstoned rows untouched, idempotence, mixed populations.
Updates docs/systems/activity-presence.md (Connect/Disconnect Flow, new Boot
Reset section) and docs/systems/auth.md (login no longer mutates status).
