Constraint: GitHub resolves workflow dispatches from the target branch ref, not just from main
Rejected: Reuse the stale branch state | the Boss Windows job could not find the builder module and failed before packaging
Confidence: high
Scope-risk: narrow
Directive: Boss-only snapshot branches must include both the workflow file and the builder script before dispatch
Tested: Boss mac build succeeded locally from the same source bundle
Not-tested: Refreshed Boss Windows workflow before rerun
