How TrashTalk evolved from a student experiment into a structured developer comparison tool with deterministic scoring, verified evidence, and unit/integration test suites.
Every original script, parser, and template remains in the legacy/ directory as a tribute to continuous learning.
Single-threaded WSGI server with synchronous route handlers blocking on external HTTP requests.

}A mathematical scoring engine locks the verdict. The commentary engine provides concise persona roasts without altering the winner.
