V-ARCH-02 — Production code used only by tests#

Production code used only by tests. It examines repository-wide reachability, dependencies, resources, and API boundaries.

Availability#

Not available in source-scan. There is no source-scan flag to activate this condition.

Example and action#

Illustrative design scenario, not a runnable Swift example or a reproduced analyzer result. The stated availability and evidence boundaries still apply.

Before: A fixture factory ships in the application even though only the test target calls it.

Review the following change against the contract and build variants described above.

After: Move the factory into the test target and update test imports. First confirm that no shipping target or generated registration uses it.

Intended analysis#

Intended reasoning: Model declarations, uses and entry points as a graph. A dependency or visibility decision needs the relevant consumers and build variants; an absence claim additionally needs a closed, complete graph. Required evidence: reachability, dependency, resource, and API-boundary facts

Assumptions and unknown#

The relevant facts must be admitted for the selected immutable build world. Unknown aliases, external effects, unsupported source forms or incomplete consumers can prevent a conclusion. Availability in this workflow is stated above; the illustration does not expand that availability.

Evidence and interpretation#

The target catalog describes the intended condition. It is not evidence of an active source-scan diagnostic.

Historical evidence at 4558458d: accepted-subset (a limited set of source forms and profiles passed historical checks). That evidence has not been requalified for this product revision.

How we validate checks explains the evidence boundary. Foundations separates method assumptions from implementation claims.
