The Complete Guide

Trust Score

A single letter grade — A to F — that tells you whether your app's critical foundation is safe for real users with real money.

What Trust Score measures

24 automated safety checks across auth, billing, and admin. A hard gate blocks grade A if any critical (P0) check fails. Architecture checks are measured separately by the AI Chaos Index.

Label guide

criticalP0 — fix before launch. -5 points each.
importantP1 — fix soon. -3 points each.
recommendedP2 — worth addressing. -2 points each.
autofixCopy the fix prompt into your AI tool.
reviewVerify manually after fixing.

Trust Score measures Production Foundation — the ASA layer that protects auth, billing, admin, and environment safety. Based on the ASA Standard.

Grade scale & scoring

Trust Score = 100 - deductions

critical failure (P0) = -5 points each

important failure (P1) = -3 points each

recommended failure (P2) = -2 points each

GradeScoreWhat it means
A90–100Production-ready. Ship with confidence.
B80–89Almost ready. A few improvements needed.
C70–79Significant gaps. Fix before accepting paying users.
D55–69High risk. Do not launch without intervention.
F0–54Critical failures. Immediate expert review needed.

Hard gates

Any P0 (critical) failure blocks grade A — regardless of numeric score. Three or more P0 failures cap the grade at F.

Deterministic scoring — the same codebase always produces the same score. Based on the ASA Standard. Not a certification or full security audit.

Why billing, auth, and admin?

AI tools generate code that works in development but skips critical safety patterns — webhook verification, row-level security, server-side auth checks. These gaps are invisible until a real user exploits them.

Auth, billing, and admin are the three layers where these gaps cause immediate, measurable damage:

🔐Auth failures expose user data

A missing RLS policy means any logged-in user can read another user's data. A client-side auth check means any developer tool can bypass it. These gaps are invisible until someone exploits them.

Data breach, GDPR violation, user trust loss

💰Billing failures cause revenue loss

An unverified webhook means a failed payment still triggers subscription activation. A client-side price check means users can buy at $0. These failures only show up in your bank account.

Revenue fraud, chargebacks, Stripe account suspension

👥Admin failures enable privilege escalation

An unprotected admin route means any user can access admin functions by guessing the URL. A hardcoded admin credential means one leaked env file compromises everything.

Unauthorized admin access, data manipulation, business disruption

AI tools generate code for the happy path. They don't think about what happens when the payment fails, the token is stolen, or the admin URL is guessed.

The Core Launch Risks

These are the founder-facing consequences of auth, billing, and admin failures — what goes wrong when the critical foundation has gaps. Each risk is backed by real incidents and maps directly to Trust Score checks.

LR-05

Your Admin Panel Has No Lock. Just a Sign That Says 'Admin Only.'

Your app has an admin panel. It's hidden from the navigation — regular users don't see a link to it. The admin dashboard shows user management, billing override

LR-08

Your Login Check Is Lying.

Your app has authentication. Users log in. Protected pages redirect to the login screen. The auth flow works perfectly in every test.

LR-07

They Cancelled. They Still Have Access. You're Losing Money.

A customer cancels their subscription. Stripe processes the cancellation. The customer still has full premium access in your app. Tomorrow. Next week. Next mont

LR-06

Stripe Will Retry Until It Breaks You.

When your server takes too long to respond, returns an error, or drops the connection, Stripe retries the event. Retries escalate from seconds to minutes to hou

LR-03

Anyone Can Upgrade to Pro for Free. Here's How.

Your app has a free tier and a paid tier. Users sign up, enter their card, pay through Stripe, and unlock premium features. The flow works perfectly in testing.

LR-01

Your Database Is Public. You Just Don't Know It Yet.

Your app has a login page. Users sign in. The dashboard shows their data. Everything works exactly as expected.

LR-02

One Exposed Key Gives Strangers Full Access to Your Database

Your Supabase project has two keys. The `anon` key is public — it's designed to be in the browser. The `service_role` key is the master key. It bypasses all Row

LR-04

Your Stripe Webhook Trusts Strangers. It Shouldn't.

Your Stripe webhook endpoint is a URL. It accepts POST requests. When Stripe sends a payment event, your app processes it — activates a subscription, grants cre
