Description
The clawdis send command fails to send messages to WhatsApp groups. Group JIDs are incorrectly converted to individual chat format, causing "gateway timeout" or silent failures.

Reproduction Steps

• Start Clawdis gateway with WhatsApp connected
• Run: pnpm run clawdis send --to "123456789-987654321@g.us" --message "Test"
• Observe gateway timeout or incorrect recipient

Expected Behavior
Message should be sent to the group chat with JID 123456789-987654321@g.us

Actual Behavior
The group JID is converted to an individual chat format:

Input: 91xxx-xyz@g.us
Sent to: 91xxxxyz@s.whatsapp.net (incorrect!)
The - is stripped and @g.us is changed to @s.whatsapp.net, causing the message to fail.

Root Cause
The toWhatsappJid() function in src/utils.ts unconditionally normalizes all inputs as phone numbers and appends @s.whatsapp.net, ignoring existing JID formats.

Similarly, sendMessage() and sendComposingTo() in src/web/inbound.ts always construct JIDs with @s.whatsapp.net.

Fix
Check if the input already contains @ before transforming:

src/utils.ts:

typescript

export function toWhatsappJid(number: string): string {
  // Preserve group JIDs (@g.us) or any existing JID format
  if (number.includes("@")) {
    return number;
  }
  const e164 = normalizeE164(number);
  const digits = e164.replace(/\D/g, "");
  return `${digits}@s.whatsapp.net`;
}

src/web/inbound.ts

typescript
const jid = to.includes("@") ? to : ${to.replace(/^\+/, "")}@s.whatsapp.net;

Environment

• OS: Ubuntu 24.04
• Node: v22.21.1
• Clawdis: v2.0.0
