An empty answer is not a yes

A five-yes fit line counts yes only when the text already says yes. Unknown stays unset (a dash) — never guessed from a blank field.

Thesis: Blank is not evidence. A yes mark requires text that already supports the criterion. Until then the mark stays unset, and “all five yes” stays false.

What we shipped first

We shipped a read-only five-yes fit line for an identified cohort. Each mark is yes, no, or unset. The failure mode we guarded against: treating an empty field as a soft yes so the line looked greener than the notes supported.

The scorer only returns yes when the existing text matches. Empty stays a dash. A row is “all five yes” only when every mark is already yes — never by filling gaps with guesses.

The working shape

For each criterion, read the fields you already have. If the text clearly supports yes (or no), mark it. If the field is blank or silent, leave unset. Summaries may count how many rows are all-unset or all-five — they must not invent marks to get there.

// Yes only when the text already supports it. Blank stays unset.
function mark(text, yesPattern) {
  if (!String(text || "").trim()) return "—"; // unset, not yes
  return yesPattern.test(text) ? "Y" : "—";
}

// allFiveYes is true only when every criterion is already "Y".

Observe blank fields scored as yes, name the guess, choose unset (dash), then prove all-five stays false. Commands: observe · why · fix · prove.
