Remote-control bridge heals a socket whose heartbeats keep failing

A remote connection with failing heartbeats now rebuilds itself instead of hanging on a half-dead socket.

What

The CCR v2 transport now spots heartbeats failing repeatedly while the SSE read stream still looks healthy, and closes the socket with code 4093 so the bridge rebuilds the transport instead of sitting on a half-dead connection.

Details
  • close code 4093 has its own recovery entry reporting reconnectingDetail: "presence heartbeats failing — reconnecting"
  • a successful rebuild emits the presence code recovered_heartbeat_4093
  • gated on tengu_bridge_selfheal_heartbeats whose in-source fallback is true, so absent a remote value it runs
  • additionally requires !outboundOnly

Feature flag
tengu_bridge_selfheal_heartbeats On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

What has happened since
Flag reading moved The flag server now returns on for tengu_bridge_selfheal_heartbeats, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
