The CFO asked only for the mix. Shares are measured against total opex of $8.0M.\n\nBackground: the categories come from the general ledger roll-up used in the monthly package. Salaries and benefits include bonuses and payroll taxes. Software includes the CRM, finance systems and developer tools. Travel is mostly sales and customer visits. Other operating costs include rent, insurance and professional fees. The mix chart goes on page 4 of the board deck.","rules":[{"type":"plainText"},{"type":"maxWords","max":70},{"type":"maxBullets","max":0}],"promptHints":[{"label":"Names the five lines","patterns":["salaries:","software:","travel:","other:","check:"]},{"label":"Gives the base","patterns":["\\$8\\.0m","total"]},{"label":"Asks for the check","patterns":["check"]},{"label":"Bans cut talk","patterns":["(do not|don'?t).*(cut|ceo|target)"]},{"label":"Caps length","patterns":["\\d+\\s*words","plain"]}],"mistakes":[{"title":"Suggesting travel cuts","why":"The AI comments that travel is small and cuts won't help.","fix":"Add: \"Facts only.
