fix(qqbot): restore AcpBridge session loading — return input sessionId, patch catch path (#7722)

AcpBridge.loadSession() has been returning response.sessionId since introduction, but ACP’s LoadSessionResponse schema does not include a sessionId field — so response.sessionId is always undefined.

The QQChannel originally worked around this with fixRestoredSessions() that reads the raw persist file and patches the router maps. However, after SessionRouter added validation in PR #5978, restoreSessions() throws on undefined sessionId, and the .catch() handler never called fixRestoredSessions().

Before PR #6457 this was masked by WebSocket RESUME — the QQ-level session recovery meant restoreSessions() was never reached on reconnect. PR #6457 added tryResume=false on non-1000 close, triggering full cold-start restore on every reconnect.

Fix:

AcpBridge.loadSession() returns sessionId directly (ACP protocol design: LoadSessionResponse omits sessionId because client knows it)
QQChannel READY catch handler now calls fixRestoredSessions() so the workaround runs regardless of restoreSessions() outcome

Fixes #7721

The open-source AI coding agent that lives in your terminal.

Why Qwen Code?

Agentic out of the box — Auto-Memory, Auto-Skills, SubAgents, Agent Teams, and MCP. Dynamic workflows, zero setup.
Open-source, inside and out — The framework and the Qwen models are open-source. They evolve together. No vendor lock-in.
Multi-protocol — Supports OpenAI, Anthropic, Gemini, and Qwen APIs. Any third-party provider or local model (Ollama / vLLM). Switch at runtime.
Beyond the terminal — IDE plugins, Desktop app, daemon mode, SDKs, and IM bots (Telegram / DingTalk / WeChat / Feishu).

[!TIP] Qwen Code is actively iterating on itself — using its own agent and models to file issues, submit PRs, review code, and run tests. Powered by the community, driven by AI.

Acknowledgments

This project was originally based on Google Gemini CLI v0.8.2. We gratefully acknowledge the Gemini CLI team’s excellent work. Starting from Qwen Code v0.1, we stopped syncing with upstream and began independent development as a multi-protocol, multi-platform agent framework with deep integrations for Qwen models and beyond.
