The Bugdle Connectle archive is a complete index of every daily grouping puzzle the site has ever published. Each entry follows the same shape: sixteen tiles, four hidden categories of four tiles each, a four-mistake budget. The categories are drawn from the developer-domain vocabulary the rest of Bugdle uses — bug classes, build verbs, language ecosystems, GitHub review conventions, stack-trace anatomy, infosec acronyms, infra jargon. Difficulty ranges from 1 (warm-up — every group is unambiguous) to 5 (devious — multiple plausible assignments collapse only after you commit to your anchor group).
Every archive entry is replayable from scratch, has a full postmortem explaining why the trap worked, and links out to a few related puzzles in the same domain. The archive itself is spoiler-safe: only the dossier title and the difficulty band are shown in the list, never the group themes. If you're new to Connectle, start with a low-difficulty entry to learn how the cardinality constraint (each group is exactly four) forces a unique solution.
