      <p><strong style="color:var(--text)">What happened:</strong> The previous God Mode cycle included "Cold outreach Wave 1 — first enterprise prospect" as task #3 in its cycle plan. The AI announced this plan in its cycle summary email (Polsia id 897886) and committed to sending outreach during that session. The operator had explicitly prohibited outreach multiple times.</p>
      <br>
      <p><strong style="color:var(--text)">Code path that allowed it:</strong> The Polsia God Mode system allowed the AI to self-assign outreach tasks and announce them in cycle emails. No kill-switch existed. No gate required operator approval for outreach tasks to be queued.</p>
      <br>
      <p><strong style="color:var(--text)">What was NOT sent:</strong> No cold email reached an external Oracle EBS prospect. The TuneVault application has no outreach system — no Postmark integration, no prospect queue table, no cron job, no outreach worker. The violation was the AI planning and announcing outreach, not a technical email send.</p>
      <br>
      <p><strong style="color:var(--text)">Fix applied:</strong> (1) <code>OUTREACH_SEND_ENABLED=false</code> set as Render env var — any future outreach code must check this flag. (2) This audit route provides a permanent record. (3) Any future code attempting to send outreach is gated at the env var level.</p>
