[Bug]: Gateway startup notification not sent.

[tatchanon51]

Bug Description

Summary

The Gateway design to sends a "♻️ Gateway online" notification only on planned restarts (e.g. hermes gateway restart, /restart command), but it’s actually not happened. This leaves the user unaware that the gateway has come back online.

Environment

• Hermes version: latest (gateway running on macOS)
• Affected platforms: all platforms that use _send_home_channel_startup_notifications (Telegram, LINE, Discord, etc.)

Steps to Reproduce

1. Start gateway: hermes gateway start (all channels connect normally)
2. Use ‘hermes gateway restart’ or ‘hermes gateway stop’ or force quit Hermes (Cmd+Q) or kill the gateway process — shutdown notification is sent as expected
3. Start gateway again if the gateway has been stopped if not, just wait gateway finish restarting: hermes gateway start
4. ❌ No "♻️ Gateway online" notification is sent to the home channel

Expected Behavior

Every time the gateway starts successfully, "♻️ Gateway online — Hermes is back and ready." should be sent to configured home channels — except when a chat-originated /restart is in flight (its reply target already covers that lifecycle).

Actual Behavior

The startup notification is designed to sent only when planned_restart_notification_pending == True, which is set only on terminal / SIGUSR1 / service paths.

Affected Component

Gateway (Telegram/Discord/Slack/WhatsApp)

Messaging Platform (if gateway-related)

Telegram

Additional Logs / Traceback (optional)

Root Cause Analysis (optional)

File: hermes-agent/gateway/run.py
Lines: 7307–7313

`if planned_restart_notification_pending:    # ← only this branch sends notification
    try:
        await self._send_home_channel_startup_notifications(
            skip_targets=None,
        )
    finally:
        _clear_planned_restart_notification()
# No else branch for manual/crash recovery`

The _send_home_channel_startup_notifications() function itself correctly respects gateway_restart_notification: True (the default), but it is never called on non-planned startup paths.

Proposed Fix (optional)

Add an elif branch right after line 7313 in hermes-agent/gateway/run.py:

`elif not _restart_notification_pending():
    # Also notify on manual start / crash recovery / service restart
    try:
        await self._send_home_channel_startup_notifications(
            skip_targets=None,
        )
    except Exception as exc:
        logger.warning("Startup notification (non-planned) failed: %s", exc)`
