ECMA-426 DecodeSourceMapSources reads a content slot only while its index is within sourcesContent, so a shorter array leaves trailing sources without content and a longer array adds no sources. Local application analysis and browser collection rejected any length mismatch and dropped every original from the map. The content helper now checks only entry types. Browser collection drops its separate check because the leaf schema already validates every supplied entry, and the raw records are still budgeted before parsing. Fixes #2821
