LEXI

Add a new word, phrase, grammar point, lesson, or TCF exercise topic.

First Class call. Returns LEXI character, methodology, teacher params, and learner state. Marks the Class conversation as started.

Format registry for Class tests: choice, fill, translate, order, match. Schema and example per format. No listen.

Card only: once the learner finishes the block in LEXI, returns the message the card posts in this chat.

Read results of a Class block after the learner finishes in the app.

Save the Class block analysis and free the next block. comment and message are shown to the learner in LEXI. Do not write to the learner in chat; put anything you want to tell them into message, it is shown in LEXI.

Next Class words from the 3000-word plan: new, review, recent errors, plus block requirements from teacher settings.

Send test content to Class and open it in the app. items: one per word with word, question, answer, correct, exactly 3 wrong answers, and pronunciation (how to read the word). LEXI builds the tests in the teacher's formats, saves the content for later blocks, and adds stored content for due words. Without items it builds from stored content. An unfinished block is returned as is. Do not write to the learner in chat; put anything you want to tell them into message, it is shown in LEXI.

Send a list of chat words to the app as a lesson, or test content for Class: give each item pronunciation, answer (the correct answer), and notes ["question: …", "wrong: …" ×3]; LEXI then builds a Class block and shows its card. The server opens the session. Pass sessionId only after start_session. Items show under Сегодня. Rejected when repeat is on and an item has status review: practice those items with get_due_items and record_answer before adding new ones. Rejected when the plan review block is due: practice that block with get_due_items and record_answer before a new block. Status new counts only toward newItems. Rejected when items still in status new would exceed the plan newItems limit; a lesson counts each of its items.
