Availability below refers to source-scan at product 524fa07e.\n\n## V-ARCH-07 — Disallowed component cycle\n\nDisallowed component cycle. It examines repository-wide reachability, dependencies, resources, and API boundaries.\n\n### Availability\n\nNot available in source-scan. There is no source-scan flag to activate this condition.\n\n### Example and action\n\nIllustrative design scenario, not a runnable Swift example or a reproduced analyzer result. The stated availability and evidence boundaries still apply.\n\n**Before:** FeatureA depends on FeatureB, which depends back on FeatureA despite an acyclic layer policy.\n\nReview the following change against the contract and build variants described above.\n\n**After:** Move the shared interface into an allowed lower-level module and make both features depend on it. Recheck the complete component graph; moving an import alone may leave another cycle.\n\n### Intended analysis\n\nIntended 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\n\n### Assumptions and unknown\n\nThe 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.\n\n### Evidence and interpretation\n\nThe target catalog describes the intended condition. It is not evidence of an active source-scan diagnostic.\n\nHistorical 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.\n\n[How we validate checks](https://docs.swift-analyzer.com/concepts/validation/) explains the evidence boundary. [Foundations](https://docs.swift-analyzer.com/concepts/foundations/) separates method assumptions from implementation claims.\n","anchors":["disallowed-component-cycle","V-ARCH-07","availability","example-and-action","intended-analysis","assumptions-and-unknown","evidence-and-interpretation"]}
