  "message": "refactor(bigtable): 1x heartbeat + drop `active :\u003d 1` code smell\n\nTwo follow-ups after the java-bigtable heartbeat cross-check:\n\n1) handleSessionParameters: drop 3x multiplier on nextHeartbeatDeadline\n   (already done in resetHeartbeatDeadline in the prior PR-2 commit).\n   Now 1 * interval, matching Java\u0027s SessionImpl.java:440 which sets\n   nextHeartbeat \u003d now + heartbeatInterval on every reset. Wake-comment\n   updated to reflect the new arithmetic.\n\n2) heartBeatLoop:\n   - Delete the `active :\u003d 1 // multiplex\u003d1; kept as %d so a future \u003e1\n     stays greppable` code smell. Inline `1` was documenting itself;\n     the variable existed only for its comment. Drop it — when\n     multiplex \u003e 1 lands, the caller will read `s.activeVRPCCount()`\n     (or similar), not this stale scaffolding.\n   - `lastFrameAge \u003d interval - remaining` (was `3*interval - remaining`)\n     to reflect the new 1x deadline.\n   - Debugf/recordEvent format strings drop the `in_flight\u003d%d` field\n     that was carrying the constant `1`.\n\nTest adjustments:\n- TestHandleSessionParameters_UpdatesIntervalAndDeadline: expect\n  deadline ~\u003d before+interval (1x) instead of before+3*interval.\n- TestHeartBeatLoop_HeartbeatsKeepInflightVRPCAlive: seed deadline\n  at now+30ms (1x) instead of now+90ms (was 3x).\n",
