# Use a known-answer dataset to inspect an AI analysis method

Use a small control case to reveal grouping, missing-value and arithmetic errors.

Use the supplied source as authority. Check the account supports the actual file or image operation before attempting it.

## Task instruction

Analyse this small control file before applying the method to my larger file.
Group by the supplied category. Preserve unique record IDs.
Report the known subtotal, numeric count and unavailable count separately.
A blank amount is unknown; an explicit zero is a known number.
Show which source rows contribute to each answer. Stop if a record ID
is duplicated or missing, a group is outside the supplied set, or an
amount contains invalid text. Return the calculation method and actual file.

## Source boundaries

- A: 10, 0, unknown
- B: 5
- Stable unique record IDs

## Review and correction

A duplicate zero row leaves the sum unchanged. Row counts and key checks reveal the error that a total-only test misses.

The method treated the blank amount as a known zero. Preserve its unknown
state and report it separately from the known subtotal. Show the affected
formula or calculation, rerun the original control and the blank-to-zero
change, and return the updated file. Do not hide the failure by changing
the expected answer or replacing invalid inputs with zero.

Use references/practice-source.json for the labelled example. The practice HTML is a local teaching tool; it does not call an AI service. Apply this method to the user's supplied facts rather than copying fictional example values. Do not infer approval or permission to publish.
