WalkthroughAdds a new Express server for audio analysis, updates a Zod-based user schema and inferred type, and makes a minor README spacing change. The server handles file uploads, calls analyzeTrack, returns JSON, and cleans up files. Schema introduces new fields and alters a profile.joined type. Changes

Restore valid Zod builders for new fields.
The new schema uses z.datesdsd, z.urlsdsd, z.strinsdsg, and UserSchemassss, none of which exist on the Zod API. This will throw at runtime and break type inference. Revert to the correct builders and reference the actual schema symbol.

In fools/files.ts around lines 25 to 32, the schema uses non-existent Zod
builders (z.datesdsd, z.urlsdsd, z.strinsdsg) and an incorrect schema identifier
(UserSchemassss); replace them with the correct Zod API and symbol: use z.date()
for dates, z.string().url({ message: "Invalid address URL" }).optional() for the
address, z.string() for plain strings, and reference the actual schema name
(e.g., UserSchema) in the z.infer type so runtime errors and type inference are
restored.

🛠️ Refactor suggestion | 🟠 Major
Rename constants to camelCase to meet style guideline.
Project guidance requires camelCase variable names. Please rename PORT and CLIENT_ORIGIN accordingly and update their usages.
-const PORT = process.env.PORT || 3001;
-const CLIENT_ORIGIN = process.env.CLIENT_ORIGIN || 'http://localhost:5173';
+const port = process.env.PORT || 3001;
+const clientOrigin = process.env.CLIENT_ORIGIN || 'http://localhost:5173';
-app.use(cors({ origin: CLIENT_ORIGIN }));
+app.use(cors({ origin: clientOrigin }));
-app.listen(PORT, () => {
- console.log(`Server listening on http://localhost:${PORT}`);
+app.listen(port, () => {
+ console.log(`Server listening on http://localhost:${port}`);
});🤖 Prompt for AI Agents
In fools/trials.ts around lines 18 to 19, the exported environment constants are
named in ALL_CAPS which violates the project's camelCase style; rename PORT to
port and CLIENT_ORIGIN to clientOrigin, update any local references and
exports/imports accordingly, and run a project-wide search to update all usages
(including other files and tests) to the new camelCase names, then run the
linter to confirm style compliance.

* - Role enumeration (admin, user, manager)
* - URL validation for website field
* - Status literal values
* - Template literal pattern for user codes
* - Strict profile object with optional bio and joined date
