The test "stops after hitting max reconnect attempts" in `src/web/auto-reply.web-auto-reply.reconnects-after-connection-close.e2e.test.ts:156-195` expects the monitor to stop after max attempts, but with this change, the monitor will continue indefinitely. Update the test to either abort the monitor or verify it continues with periodic recovery attempts.

Existing test will timeout/fail
The test "stops after hitting max reconnect attempts" in auto-reply.web-auto-reply.reconnects-after-connection-close.e2e.test.ts (line 156) relies on await run resolving after max attempts are reached. Previously, the break statement caused monitorWebChannel to return, resolving the promise.
With this change, the loop continues indefinitely after max attempts. Since the test's mock sleep resolves immediately, the loop will call listenerFactory a 3rd time, creating an onClose promise that nobody resolves — causing the test to hang until its 60-second timeout.
The test needs to be updated to reflect the new behavior, for example by:
- Using an
AbortControllerto stop the loop after verifying the "max attempts reached" log, or - Continuing to resolve
closeResolversand asserting on the continued retry behavior.
The PR description states "Existing tests pass" but this test should fail with the current changes.

Repeated warn/error on every recovery cycle
Once maxAttemptsReached is true, this entire block (warn log + runtime.error) fires on every recovery iteration — i.e. every 60 seconds by default. Since reconnectAttempts keeps incrementing without bound until a healthy connection resets it (line 348), the gateway will emit a warn-level log entry and a runtime.error() call every heartbeat interval indefinitely while disconnected.
Consider logging the "max attempts reached" message only on the first transition (when reconnectAttempts === reconnectPolicy.maxAttempts), and using a quieter log level (e.g. info or debug) for subsequent periodic recovery attempts. This avoids log spam in long outage scenarios while still keeping the initial alert visible.
Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Summary
Instead of permanently stopping after max reconnection attempts (default 12), the WhatsApp gateway monitor now continues with periodic recovery attempts using the heartbeat interval. This allows the WhatsApp connection to automatically recover without requiring manual gateway restart after transient disconnections that occur after long uptime (8-12 hours).
Changes
src/web/auto-reply/monitor.ts: When max reconnection attempts are reached, the code now continues with periodic recovery attempts (every 60 seconds by default) instead of breaking out of the monitoring loop entirely.Testing
Fixes #17475
Greptile Summary
This PR changes the WhatsApp reconnection behavior so the gateway no longer permanently stops after exhausting max reconnection attempts (default 12). Instead, it transitions to periodic recovery attempts at a fixed interval (
heartbeatSeconds, default 60s). This addresses a real operational pain point where transient disconnections after long uptime required manual restarts.monitorWebChannelreplaces thebreakafter max attempts with a fixed-interval retry usingheartbeatSeconds * 1000as the delay, while preserving exponential backoff for initial attempts.reconnectAttemptsreset at line 348 (when uptime exceeds heartbeat interval) ensures the counter resets after a successful recovery, restoring normal backoff behavior.runtime.error()in themaxAttemptsReachedbranch fires on every recovery cycle (not just the first), which will produce repetitive log output during extended outages."stops after hitting max reconnect attempts"expectsmonitorWebChannelto return after max attempts. With this change, the loop continues indefinitely, which will cause that test to hang (as noted in previous review thread).Confidence Score: 3/5
src/web/auto-reply/monitor.ts— verify that the e2e test"stops after hitting max reconnect attempts"is updated to reflect the new never-terminate behavior, and consider reducing log verbosity during periodic recovery.Last reviewed commit: 043e542
