Launch night's worklist is an array with a push endpoint

Product Hunt day, 8:00 PM. Signups are arriving faster than the welcome flow can process them: every new account needs a workspace seeded, an email sent, a webhook fired.

The buffer between intake and worker is one key in SQLite. The signup handler calls POST /api/v1/sqlite/kv/signups/push?db=app.db: an atomic append in a single round-trip, no read-modify-write race. The worker daemon calls /pop and processes whatever it gets. Two hundred concurrent pushes stay two hundred clean entries, because the mutation happens inside the store, not in your code.

By 11:00 PM the array is empty and 1,240 accounts are seeded. Redis was never installed. A queue service was never even evaluated.
