Testing

The final set, and what stands behind it

408 items that passed every automatic check and both content gates: one of each kind of material for each grade band and course tested, across 24 courses from Kindergarten to Grade 12. Below them, the protections every item passes through, and the evaluation runs that measured them.

These are the strongest examples from the evaluation runs, chosen by the checks, not by hand. Verified means every automatic check and both content gates passed; Reviewed means a signed-in reviewer approved it as well. Open any item to see its checks, its sources and its downloads. The full gallery holds every example, including the ones held for review.

Check	Severity	Applies to	What it checks
`schema_valid`	blocking	every kind	The stored body and parameters match the kind's schema.
`question_count_matches`	major	Quiz, Homework sheet	A quiz or sheet has exactly the number of questions requested.
`every_question_has_answer`	blocking	Quiz, Homework sheet	Every question has an entry in the answer key.
`item_types_match`	minor	Quiz	Every requested item type (multiple choice, true or false, numeric, short answer) appears with its count.
`slide_count_and_layouts`	major	Presentation	A presentation has the requested slides, each with a known layout.
`slides_plain_text`	major	Presentation	No slide text carries citation residue, a raw alias or a doubled pill. The repair tidies it with no model call.
`game_word_list_present`	blocking	Game	A puzzle carries its word list.
`alt_text_on_images`	major	every kind	Every picture has alternative text.
`no_latex_or_fences`	blocking	every kind	No LaTeX, code fences or HTML leak into the text.
`no_aliases_or_markers`	blocking	every kind	No raw citation aliases or image markers remain in the body.
`no_em_dashes`	minor	every kind	House style: no long dashes.
`no_self_talk`	blocking	every kind	No model self-talk ("As an AI", "Let me", "I will now").
`no_internal_codes_in_family_output`	major	every kind	Family material carries no outcome codes or internal labels.
`language_matches_request`	blocking	every kind	The body is in the language requested.
`senior_wording`	major	every kind	Senior material never addresses "kids" or "boys and girls".
`readability_in_band`	major	every kind	Student-facing prose reads at the band's grade level (Flesch-Kincaid); teacher documents have an adult ceiling; a read-aloud story may sit two grades above the band, since listening runs ahead of reading.
`citations_resolve`	blocking	every kind	Every citation points at a curriculum node that exists.
`citations_in_scope`	major	every kind	Every citation stays inside the courses the request was about.
`citations_match_text`	major	every kind	A sentence that paraphrases one source cites that source, not a neighbouring one; the repair re-points it.
`overview_rows_in_selection`	major	Parent overview	A year-at-a-glance table lists only outcomes from the selected course.
`selected_outcomes_referenced`	major	Lesson, Lesson package, Presentation	A lesson references every outcome the person selected; a whole unit picked at once (more than eight) passes at four in five, and a deck is asked for about one outcome per content slide, with the ones left out named.
`arithmetic_in_keys`	blocking	Quiz, Homework sheet, 30-minute homework, Lesson, Lesson package	Every arithmetic statement in an answer key is recomputed and must be right.
`puzzle_solvable`	blocking	Game	Every puzzle is solved by the validator before it is served.
`diagram_spec_valid`	blocking	every kind	A code-drawn diagram's specification is complete and consistent.
`wordmap_legend_consistent`	major	Word map	A word map's legend matches its groups and colours.
`image_verdicts_accepted`	major	every kind	Every served picture passed the vision check.
`no_people_in_senior_images`	blocking	every kind	Senior-band pictures show no people.
`png_for_every_svg`	major	every kind	Every SVG board has a PNG twin for download and printing.
`audio_duration_proportional`	major	every kind	A read-aloud story's narration length matches its script.
`exports_render`	blocking	every kind	Markdown, DOCX and PDF exports render without error.
`claims_supported`	blocking	every kind	Content gate: every factual sentence is checked against the curriculum passage it cites (or, for a course-level item, the outcome beneath the cited node that it matches best). Any unsupported sentence fails.
`judge_review`	blocking	every kind	Content gate: an independent reviewer on a different model reads the whole item against the request and the passages: factual errors, grade fit, answer key and procedures, safety and bias. Any factual error, a wrong key or procedure, grade fit under 3 or a safety issue fails.
