Explain the App You Vibe Coded

Audit this repository and report:
1. What the product does, in one paragraph
2. Primary user
3. Frontend framework and main frontend directories
4. Backend framework and main backend directories
5. Third-party services and integrations
6. Where configuration and secrets are read from
7. Anything that looks unused or duplicated

Cite the file paths that support each answer.

Trace exactly what happens when a user completes this action:
[e.g. signs up / saves a record / purchases a subscription].

Walk through: the UI component → the client call → the route or
function → any validation → the database write → what comes back →
what the UI renders. Name every file involved.

Inspect the database configuration, migrations, and schema.

List every table with its columns, relationships, and indexes.
Explain what each table is for in plain English.
Flag: missing constraints, tables with no access rules, and any
column that stores sensitive data.

Audit how authentication and authorization work here.

Explain: how users create accounts, how sessions are maintained,
where permissions are enforced (client, server, or database), which
routes are protected, and what an unauthenticated user can reach.

List anything enforced only in the UI — that's not enforcement.

Report on how this app uses AI:
1. Model provider
2. Model names and configuration
3. Where model calls occur (files and functions)
4. What data is sent to the model
5. Whether any user or customer data leaves the system
6. Retry, timeout, and failure handling
7. Roughly what a call costs and what drives that cost

Identify: hosting platform, build command, start command,
environment variables required, where they're configured, how
deploys are triggered, and what would break a deploy today.

Using only the verified audit above, explain this product to:
(a) a non-technical customer, (b) an investor, (c) an engineer.

For each, include: the problem, the user, how it works, what makes it
defensible, and its current limitations. No jargon for (a).
