Express setup moves into a reusable application module, transaction workflows use dedicated Neon transaction access, scheduled cleanup moves to a Worker handler, and deployment scripts manage Wrangler secrets and the Vercel API proxy. ChangesCloudflare Workers migration
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to This PR moves request handling and database transactions to a new provider/runtime split. It is mergeable with owner awareness of two bounded risks: transaction cleanup errors may make committed operations appear failed, and expired-session cleanup may no longer run during Node startup.

In `@scripts/prepare-wrangler-secrets.mjs`:
- Around line 44-46: Update the secret parsing flow around the quote-removal
logic and the value inline-comment check so it tracks whether the source value
was quoted; only apply the hash-based comment truncation for unquoted values,
preserving hashes within quoted secrets such as “part # two”.
In `@src/db/db.ts`:
- Line 2: Update the db setup around the NeonHttpDatabase import and transaction
callers so transaction workflows use the WebSocket-capable driver, or rewrite
those workflows to avoid transactions. Ensure the transaction calls in auth,
grades, and classes complete without invoking the unsupported neon-http
transaction implementation.
In `@src/index.ts`:
- Line 2: Restore automatic expired-session cleanup for Node execution by
scheduling the existing session-cleanup logic during startup in src/index.ts,
covering both the start and dev entry points. Reuse the existing cleanup
implementation and preserve the current app initialization flow.

Keep automatic expired-session cleanup for Node starts.
package.json supports Node execution through start and dev, but src/index.ts no longer schedules cleanup. The cleanup:sessions script is manual, so Node starts can retain expired sessions. Restore a Node scheduler or remove these entry points.

In `@routes/classes.ts`:
- Line 220: Replace the module-scoped transactionDbInstance flow from
getTransactionDb() with a request-scoped transaction helper that creates a Neon
Pool, executes the transaction, and closes the pool in finally. Apply this
change at routes/classes.ts:220, routes/grades.ts:390, and src/lib/auth.ts:111,
preserving each existing transaction’s behavior.
