Expansion model

Each column should target one learner group and one repeatable puzzle format.

This keeps the AI generation problem narrow: source checks, difficulty calibration, distractor validation, and editorial review can be tuned per language track.

01Start narrowOne audience, one language pair, one puzzle shape.
02Verify before releaseCheck answer uniqueness, sources, distractors, and level fit.
03Reuse the column systemAdd new language tracks without rebuilding the whole product.

Publishing standards

AI can draft candidates, but publishing must stay verified.

Daily puzzles should only go live after answer validation, source notes, safety checks, and human sign-off. That is the difference between a useful learning column and generic generated trivia.

Puzzle Quality Review

Every published puzzle needs answer validation, distractor checks, source notes, and human editorial sign-off.

Required
Learner Fit

Difficulty, clue wording, and explanations should match a concrete learner segment instead of a generic audience.
