Four-item dehydration scale with weight-loss override: tears item order · case 05

Absent tears score 1 and decreased tears score 2.

Case contract

Input {appearance (normal|thirsty_restless|drowsy_limp), eyes (normal|slightly_sunken|very_sunken), mucous (moist|sticky|dry), tears (present|decreased|absent), weight_loss_pct (or null)}. Items score 0/1/2 in the listed order. Category: 0 NONE, 1-4 SOME, 5-8 MODERATE_SEVERE. A measured weight loss >= 10% forces MODERATE_SEVERE; >= 3% raises NONE to SOME but never lowers a category. Return {score, category}.

Why this case matters

Ordinal clinical scales combined with an objective override can fail in item mapping, band edges and override direction.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
score exactly 4	`{"category": "MODERATE_SEVERE", "score": 5}`	`{"category": "SOME", "score": 4}`	Failed
