Validate declared artifact and MVID scopes at managed Evidence admission, and reject conflicting known module declarations across graph inputs. Join boundary tokens to members only under matching known MVID scopes; preserve facts and report partial coverage when scope is unknown.
Prefer an observed MVID-bearing declaration with its supplying Evidence. Normalize GUID casing for module node identity while preserving original strings in observations.
Validation: 285 tests across 34 focused suites passed, followed by the final 12-test managed graph suite and managed CLI/MCP regressions. check:fast and architecture guards passed; no real native providers were run.
