Sample 48-Hour Codebase Audit Report: "PulseFlow AI" (Sanitized)
Stack: Lovable + Claude Code + Next.js App Router + Supabase + Stripe Billing • Auditor: Dositej Grbović (Founder & Principal Engineer)
This interactive Sample 48-Hour Codebase Audit Report demonstrates the exact complimentary diagnostic deliverable Aquarel provides for Lovable, Claude Code, Cursor, Next.js, Supabase, and Stripe applications. Audited personally by Principal Engineer Dositej Grbović, it includes a chaptered plain-English Loom walkthrough, a Red/Yellow/Green vulnerability scorecard, and a fixed-price $1,400 6-day Rescue Sprint roadmap.
Walkthrough of PulseFlow AI’s Next.js App Router layouts, onboarding screens, and normalized PostgreSQL schema. Roughly 80% of the application is clean, well-structured, and ready for production—proving why a $30k–$80k agency rewrite is unnecessary.
src/app/(marketing)/* & supabase/migrations/001_initial_schema.sql Executive Triage Summary (In Plain English)
The Good News: Roughly 80% of your application—your core Next.js UI flows, onboarding screens, and Supabase PostgreSQL table structure—is solid and should not be rewritten. Any agency quoting $30k+ to rebuild this from scratch is wasting your time and budget.
The Bad News (Must Fix Before Launch): There are 3 P0 critical vulnerabilities introduced during rapid AI prompting that currently expose customer data and drop roughly 15% of Stripe subscription upgrades, plus 2 P1 maintainability bottlenecks.
Detailed Red / Yellow / Green Risk Scorecard
| Severity | Subsystem & File Location | Plain-English Business Impact | Surgical Remediation |
|---|---|---|---|
| 🔴 RED / P0 | Supabase RLS (public.subscriptions, public.documents) | RLS was disabled by an AI migration script to "fix a permission error." Any logged-in user can read or delete another customer's documents and billing records. | Enable strict RLS with auth.uid() = user_id policies + automated multi-tenant isolation test. |
| 🔴 RED / P0 | Stripe Webhook (app/api/stripe/webhook/route.ts) | Raw body signature verification is bypassed and retries are not idempotent, causing failed account upgrades and duplicate provisioning on webhook retries. | Enforce stripe.webhooks.constructEvent + database idempotency lock table on event.id. |
| 🔴 RED / P0 | Exposed Key (src/lib/supabaseClient.ts) | NEXT_PUBLIC_SUPABASE_SERVICE_ROLE_KEY is bundled into the browser client, granting full admin database access to anyone opening Chrome DevTools. | Rotate service role key immediately; restrict admin client strictly to server-only actions. |
| 🟡 YELLOW / P1 | Monolithic Dashboard (src/app/dashboard/page.tsx — 2,840 lines) | Every Claude Code or Cursor prompt editing dashboard UI risks breaking billing state hooks and Supabase queries coupled inside the same file. | Split into 4 focused feature modules + lock core boundaries behind CLAUDE.md and AGENTS.md rules. |
| 🟡 YELLOW / P1 | SSR Auth Cookie Refresh (src/middleware.ts) | Users on magic-link and Google OAuth sessions get logged out randomly after 60 minutes when server components fail to refresh expired JWT cookies. | Implement canonical @supabase/ssr middleware session refresh and unified auth callback route. |
| 🟢 GREEN | PostgreSQL Schema, Onboarding Flows & Tailwind UI (6 Core Modules) | Normalized tables, responsive Tailwind components, and core product workflows are clean and production-ready. | Leave alone. Zero rewrite budget needed here. |
6-Day Surgical Stabilization Sprint + Vibe-Safe Handover — $1,400 Fixed Price
Includes all 3 P0 fixes, SSR auth hardening, dashboard decoupling, CLAUDE.md & AGENTS.md guardrails, staging verification, and final Loom walkthrough.
Sample Audit & Rescue Sprint FAQ
Is my actual 48-hour Codebase Audit really $0? +
Yes. After a quick 20-minute Triage Call (or async intake brief) and a mutual NDA to confirm we are a qualified fit, I perform this 48–72 hour diagnostic at $0 cost and zero obligation. You keep the Red/Yellow/Green scorecard, the 10–15 minute Loom video, and the fixed-price sprint roadmap whether you hire Aquarel or not.
Do you modify any production code during the 48-Hour Codebase Audit? +
Never. The 48-Hour Codebase Audit requires strictly read-only repository and schema inspection after we sign a mutual NDA. All code changes happen only if you approve the Fixed-Scope Rescue Sprint, and every fix ships via isolated Pull Requests in staging.
Why does the sample Rescue Sprint cost $1,400 instead of $30,000? +
Because 80% of PulseFlow AI is already healthy and should be kept as-is. Instead of billing you for weeks of unnecessary UI and schema rewrites, I spend 6 focused days surgically fixing the 3 P0 security/billing blockers, splitting the 2,840-line god-file, and installing CLAUDE.md and AGENTS.md guardrails.
