Home canning altitude table: weighted gauge band · case 02

A weighted gauge at 1500 ft is set to 10 psi.

Member previewVariant 2 · 3 implementations · 8 checks per implementation

Case contract

Above 10000 ft -> "error: altitude out of range". Water bath adds 0 (<=1000 ft), 5 (<=3000), 10 (<=6000), 15 (<=8000), 20 (<=10000) minutes to base, psi None. Dial gauge keeps base minutes, psi 11 (<=2000), 12 (<=4000), 13 (<=6000), 14 (<=8000), above 8000 error. Weighted gauge keeps base minutes, psi 10 at <=1000 ft else 15. Other methods -> "error: method".

Why this case matters

Preserving recipes must lengthen time or raise pressure at altitude to stay safe (toy table).

One recorded failure

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
regression: weighted gauge band	`{"minutes": 85, "psi": 10}`	`{"minutes": 85, "psi": 15}`	Failed
