Sleeve cap ease checker: too-little bound · case 03

Exactly 2.5 cm of woven ease is reported as too little.

Member previewVariant 3 · 3 implementations · 8 checks per implementation

Case contract

Ease = cap - (front + back armhole). Allowed ease: woven 2.5-4.5, knit 0-1.5, leather 0-0.5 (inclusive; fabric trimmed, lower-case; other -> "error: fabric"). Verdict "too little", "too much" or "ok". Adjustment per side = (midpoint - ease)/2. Return [ease, verdict, adjust] with floats rounded to 2 decimals.

Why this case matters

Set-in sleeves need a fabric-dependent amount of cap ease to ease into the armhole.

One recorded failure
