Description

When the Gateway restarts (via SIGUSR1 / config.patch), the webchat channel loses its session context entirely. A new conversation is started instead of resuming the previous one.

Expected Behavior

After a hot restart (SIGUSR1), the webchat session should either:

• Resume the existing conversation context, or
• At minimum, re-inject the session history so the agent can continue without losing context

Actual Behavior

After restart, webchat opens a brand new session with no memory of previous conversation. The user has to re-explain context from scratch.

Notes

• Other channels (QQBot, Telegram, etc.) can recover via platform-side message history
• webchat has no such mechanism, making it uniquely affected
• SIGUSR1 hot restart should ideally preserve in-process session state

Environment

• OpenClaw version: 2026.3.24
• Channel: webchat
• OS: Linux (Ubuntu)
