fix(cli): daemon restart no longer blacks out the mesh (1.37.1)
Daemon side of the 2026-09-08 incident (spec Addenda 3, 5, 6): - ws-lifecycle: createWsLifecycle() returns the handle synchronously with ready exposed separately. A first hello-ack timeout used to REJECT the connect promise while the helper kept reconnecting on its own, so DaemonBrokerClient.lifecycle stayed null forever and every RPC gated on it (listPeers, send, ...) short-circuited: peer list answered [] on all 9 meshes for as long as the daemon lived. Ack timeout 5 s → 15 s (a timeout is now just a reconnect). 1000 session_replaced is terminal for a lifecycle (two daemons no longer fight over the same sessions). - drain: 24 h outbox TTL (expired), session_gone after 10 min, attempt cap on the not-ready path, drain_session_ws_not_ready logged on attempt 1 and every 60th (was every tick: 4 rows × ~130 k attempts = a 1 GB log). - Rotating log sink (20 MB × 5, total budget) behind an explicit --log-sink flag that the launchd/systemd unit and the detached spawn pass; units point StandardOut/Err at daemon.launchd.log and pin ThrottleInterval 10. - Exit forensics: daemon_exit / daemon_uncaught on every exit path; SIGHUP is a clean shutdown. - Singleton hardening: the CLI stale-probe no longer unlinks a live daemon's pid/socket on a slow probe (only ECONNREFUSED/ENOENT or a dead pid is stale); the daemon probes the socket for another live daemon before taking the lock and re-asserts its pid file every 30 s. - MCP SSE: resubscribe on every termination event with a 45 s idle watchdog; the daemon ends open SSE streams before exiting. - Operator signal: GET /v1/diagnostics; daemon status shows per-mesh and per-session WS state; new daemon restart; doctor adds version match, member/session WS open, ghost detector (every registered session must appear in the broker peer list), log size + stale unit; peer list warns when the daemon is not connected to the broker for a mesh. Tests: ws-lifecycle (timeout → same handle, close mid-connect, session_replaced terminal), daemon-broker-lost-handle (Addendum 3 regression), drain-expiry, log-sink, sse-resubscribe (socket destroyed without end), daemon-probe-classify. Local drills against the fixed broker: SIGKILL + respawn → sessions visible at t+1 s, second daemon refused, pid file self-healed. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

## 1.37.1 (2026-09-08) — daemon restart no longer blacks out the mesh
|
||||
|
||||
Incident: after the local daemon restarted (launchd respawn), `peer list`
|
||||
returned 0 peers on every mesh for >40 min while all sessions were alive,
|
||||
sends reported `no connected peer`, and the MCP push channel went silent.
|
||||
Spec + evidence: `.artifacts/specs/2026-09-08-daemon-restart-mesh-blackout.md`.
|
||||
|
||||
### Root causes (daemon side; the broker side ships separately)
|
||||
|
||||
- `DaemonBrokerClient.connect()` awaited `connectWsWithBackoff()`, which
|
||||
REJECTED when the first hello ack timed out (5 s; the broker took 4–5 s
|
||||
under the reconnect storm) while its internal loop kept reconnecting the
|
||||
same socket. `lifecycle` stayed `null` forever, `_status` flipped to
|
||||
`open`, and every RPC gated on `this.lifecycle` (`listPeers`, `send`,
|
||||
…) short-circuited — `/v1/peers` answered `[]` in 30 ms on all 9 meshes.
|
||||
- The outbox drain retried rows bound to long-gone session pubkeys ~130 k
|
||||
times each and logged `drain_session_ws_not_ready` on every tick;
|
||||
`daemon.log` reached 1.0 GB with no rotation (launchd `StandardOutPath`).
|
||||
- The daemon that died left no log line (no crash/exit forensics).
|
||||
- The MCP plugin's `/v1/events` SSE subscription only resubscribed on
|
||||
`res 'end'`; a killed daemon produces `close`/`aborted` instead, so
|
||||
mid-turn `<channel>` injection stayed dead until Claude Code restarted.
|
||||
|
||||
### Fixes
|
||||
|
||||
- `ws-lifecycle.ts`: `createWsLifecycle()` returns the handle synchronously
|
||||
with `ready` exposed separately; a hello-ack timeout is just a backoff
|
||||
reconnect (never rejects, never orphans); `close()` works mid-connect.
|
||||
Ack timeout 5 s → 15 s. Both broker clients store the handle before
|
||||
awaiting `ready` and expose `diagnostics()`.
|
||||
- `drain.ts`: 24 h outbox TTL (`expired`), `session_gone` after 10 min for
|
||||
rows whose session is no longer registered, attempt cap on the
|
||||
not-ready path, `drain_session_ws_not_ready` logged on attempt 1 and
|
||||
every 60th.
|
||||
- Rotating log sink (20 MB × 5, total budget enforced) takes over
|
||||
stdout/stderr when the daemon runs under launchd/systemd; the service
|
||||
unit now points StandardOut/Err at `daemon.launchd.log` and pins
|
||||
`ThrottleInterval 10`. Exit forensics: `daemon_exit` /
|
||||
`daemon_uncaught` lines on every exit path; SIGHUP is a clean shutdown.
|
||||
- MCP SSE: resubscribe on every termination event, 45 s idle watchdog
|
||||
(daemon keepalive is 15 s), reconnects logged to `mcp-<pid>.log`; the
|
||||
daemon ends open SSE streams before exiting.
|
||||
- Operator signal: `GET /v1/diagnostics`; `claudemesh daemon status`
|
||||
shows per-mesh and per-session WS state; new `claudemesh daemon
|
||||
restart`; `claudemesh doctor` adds version match, member/session WS
|
||||
open, a ghost detector (every registered session must appear in the
|
||||
broker peer list), log size + stale service unit. `peer list` warns
|
||||
when the daemon is not connected to the broker for a mesh instead of
|
||||
printing a silent empty list.
|
||||
|
||||
After upgrading run `claudemesh daemon install-service` (new unit) and
|
||||
`claudemesh daemon restart`.

||||

||||

* Rotating log sink for the daemon (1.37.1).
|
||||
*
|
||||
* Why this exists: the daemon writes JSON lines to `process.stdout` /
|
||||
* `process.stderr` from ~20 call sites, and under launchd / systemd those
|
||||
* streams were redirected straight into `~/.claudemesh/daemon/daemon.log`
|
||||
* by the service unit (`StandardOutPath`). launchd does not rotate — the
|
||||
* 2026-09-08 incident found a 1.0 GB `daemon.log` (disk at 95 %), most
|
||||
* plausibly the reason the daemon died silently.
|
||||
*
|
||||
* The sink takes ownership of both streams in-process: every write is
|
||||
* appended synchronously to `path` through our own fd, and the file is
|
||||
* rotated when it reaches `maxBytes` (`path.1` … `path.<keep>`, oldest
|
||||
* deleted). A total-size budget (`keep × maxBytes`) is enforced across
|
||||
* the rotated archives so a pre-existing oversized file cannot pin the
|
||||
* disk after upgrade.
|
||||
*
|
||||
* Failure policy: a throw anywhere inside the sink must NEVER take the
|
||||
* daemon down. On any error the sink falls back to the original
|
||||
* `write` for that call (which goes wherever launchd pointed stdio —
|
||||
* `daemon.launchd.log` on 1.37.1+ units, the old path on stale units).
