Duplicate samples mask an unqualified mold cavity · case 04

Duplicate samples mask an unqualified mold cavity.

Member previewVariant 4 · 3 implementations · 7 checks per implementation

Case contract

Active cavity IDs are unique. Chronological samples are (cavity, passed) pairs. Gate opens iff each active cavity latest sample passes; inactive cavities are irrelevant.

Why this case matters

A deterministic manufacturing record model isolates this workflow defect before equipment or enterprise integration.

One recorded failure

Sample boundary fixture

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

Boundary fixture	Actual	Expected	Outcome
duplicates hide missing cavity	`true`	`false`	Failed
