Convert constructor arguments in Web IDL order before processing blob parts, including inherited dictionary members and File.lastModified's long long conversion. Read buffer slots and copy bytes without invoking user getters, slice methods, or species constructors. Treat detached parts as empty and track Blob brands without invoking user getters or accepting proxies. Keep rejecting bare SharedArrayBuffers and shared-memory views for browser compatibility pending resolution of the union conversion rules.

Convert Blob and File constructor arguments before processing blob parts, preserving Web IDL argument and dictionary conversion order. Apply
long longconversion toFile.lastModifiedand reject an explicitly undefinedfileBitsargument.Copy bytes using internal buffer slots without invoking user getters, slice methods, or species constructors. Treat detached parts as empty and check Blob brands without invoking user getters or accepting proxy wrappers.
Keep rejecting bare SharedArrayBuffers and shared-memory views for browser compatibility. String conversion for bare SharedArrayBuffers remains an unresolved specification discrepancy: whatwg/webidl#1491.
I'd treat Web API fixes as patches but since the impact of this is unclear to me -> semver-majorPRs that contain breaking changes and should be released in the next major version.
