storybored379andClaude Opus 5.5 01753f90f3 File: file.serialize returns the file's bytes (base64) — web Save wrote corrupt documents
file.serialize returned {json: String::from_utf8_lossy(to_bytes(doc))},
but since M6.1 the native format is a zip (deflated document.json + raw
assets), not JSON text. from_utf8_lossy turns every invalid UTF-8
sequence into U+FFFD, so the result is not the file: on the web, File ›
Save downloads exactly those bytes (download_document), and the
downloaded .designcraft can't be opened again ("invalid Zip archive").
Agents calling file.serialize got the same unusable string.

Return {base64, bytes} like the other byte-producing commands
(file.exportIdml, file.exportPdf, snippet.export) and decode it in
download_document.

Test: serialized_document_opens_again.
