Side A rips out a genuinely broken, overengineered keystroke-transition parser (1800+ lines of fragile graph/backtracking logic plus a Playwright race test) and replaces it with a small, correct, testable subreddit-URL parser and simple paste-and-go UI, net-simplifying the codebase while fixing real reliability issues. Side B adds a reasonable but purely auxiliary dev CLI (sorterc) that duplicates server logic for offline linting/compiling—useful tooling but lower-stakes and more speculative than fixing a broken core UX flow shipped to users.
