Generated file ownership: Only one output of a generator is registered · case 05

Only one output of a generator is registered.

Member previewVariant 5 · 3 implementations · 7 checks per implementation

Case contract

Map output names to producing rules. Skip disabled rules, include all declared outputs, reject duplicate owners, retain owner names, and return sorted pairs. Duplicate declaration by the same owner is harmless.

Why this case matters

An offline model of generated file ownership, suitable for testing build and release tooling without external services.

One recorded failure
