Problem

When resuming a Claude session with --resume <session_id>, Claude may return a different session ID in its JSON output than the one requested. Currently, warelay doesn't track this, so subsequent messages may fail to continue the conversation properly.

Proposed solution

1. Extract session_id from Claude's JSON output in command-reply.ts
2. Compare returned session ID with the requested one
3. If different, update the session store with the new ID

Affected files

• src/auto-reply/command-reply.ts - add extractClaudeSessionId() and include sessionId in CommandReplyMeta
• src/auto-reply/reply.ts - update session store when Claude returns a different session ID

Implementation

// command-reply.ts
export function extractClaudeSessionId(payload: unknown): string | undefined {
  if (!payload || typeof payload !== "object") return undefined;
  const obj = payload as Record<string, unknown>;
  return typeof obj.session_id === "string" ? obj.session_id : undefined;
}

// reply.ts - after getting response
if (meta.sessionId && sessionStore && sessionKey && meta.sessionId !== sessionId) {
  sessionStore[sessionKey] = {
    sessionId: meta.sessionId,
    updatedAt: Date.now(),
    systemSent,
  };
  await saveSessionStore(storePath, sessionStore);
}
