Evidence: AI-generated mutation bypasses tenant boundary
Action: preflight fix app/api/profiles/route.ts
Save-time alerts in VS Code/Cursor. Native Windows popup fallback when no extension client is connected.
No account wall. No key required to start watching. Try the local daemon, then unlock unlimited remediation when the Founder's Key is in hand.

Once you have your Founder's Key, authenticate instantly via the CLI to lift all restrictions.
AI coding tools move fast, but they don't know your deep structural architecture boundaries.
A single hallucinated clause can accidentally bypass a critical Supabase RLS policy or security guardrail.
Don't wait for a failed CI/CD pipeline or a broken production database. Catch it in the editor as you type.

⚠️ Beta Architecture & Safety Notice: PreFlight Pro is currently in active Beta. While our local AST daemon is designed to catch severe structural anomalies, hallucinated syntax, and potential Supabase RLS drifts in real-time, it does not guarantee 100% error elimination. AI-assisted code should always be explicitly reviewed by a senior engineer before being pushed to a production environment. Use PreFlight as an advanced automated guardrail, not a replacement for manual code review.
