* DOCX: keep a .docm's macros on save; write .docm/.dotx/.dotm content types Saving a .docm deleted its VBA project and wrote the plain-docx main content type under the .docm name, which Word rejects; .dotx was written as a document, and .dotm could be opened but not saved. io_ext sent every Word extension to wordcraft_docx::write, which always emitted a .docx package, and the reader never kept the VBA parts. - wordcraft_docx::Flavor (docx/docm/dotx/dotm) picks the main part's content type; write_as(doc, flavor) writes it, write() stays .docx. - The reader keeps word/vbaProject.bin (and the vbaData.xml it relates to) as opaque bytes in Document::passthrough, the mechanism custom.xml already uses. Macro content is never parsed or run. The writer emits them, with their relationships and content types, only for .docm/.dotm; a .docx/.dotx leaves them out cleanly (as Word does) and the open document still holds them for a later Save As .docm. - Empty projects, missing or malformed VBA data, duplicate or odd relationships never panic and never stop the document from opening; part sizes stay under the existing package limits. - .dotm joins the open/save lists, and saving to .docm/.dotx/.dotm binds the session to that file like .docx.

That parser rejects UTF-16 (a valid XML encoding), so a UTF-16 vbaData.xml was silently dropped and the saved .docm kept vbaProject.bin without its VBA data; and it is lenient (no end-name check, auto-closes at EOF), so malformed data passed the gate anyway. WordCraft is a passthrough for macro parts: it should emit exactly what the user's file had. Now vbaProject.bin and vbaData.xml are both carried byte for byte (bounded by the reader's existing size limits); only the relationship part is read, to find the VBA data. A relationship to a missing VBA data part keeps the project and writes no dangling link. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * DOCX: read UTF-16 XML parts instead of dropping them xml::parse rejected any part with a UTF-16 BOM, and Package::rels swallowed that error as "no relationships". A UTF-16 word/_rels/vbaProject.bin.rels (valid per OPC) therefore hid vbaData.xml, and saving the .docm dropped it and its relationship. parse now transcodes UTF-16 LE/BE with a BOM to UTF-8 (lossy, bounded at 1.5x, never panics on odd lengths or unpaired surrogates), so every part benefits. Unreadable relationship parts are now logged rather than silently treated as empty; the macro project is still kept.

Save and the Save As suggestion now default to the opened file's extension when it is a Word package (.docx/.docm/.dotx/.dotm, via engine io::is_word_package), else .docx. Macros are only dropped on an explicit conversion to a macro-free name. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * DOCX: carry every part a VBA project relates to, so signatures survive A signed .docm/.dotm lost its VBA signature on save: the reader kept only vbaProject.bin and vbaData.xml, and the writer rebuilt vbaProject.bin.rels with the wordVbaData relationship alone. Under a "signed macros only" policy the macros then stop running, although the project bytes (which the signature covers) were unchanged. Generalised instead of special-casing signature types: the reader now keeps every internal part vbaProject.bin.rels points to (VBA data, the legacy/Agile/V3 signatures, anything else) as opaque bytes, with its relationship type and its content type from [Content_Types].xml, in a small manifest in Document::passthrough. .docm/.dotm re-emit them all; .docx/.dotx still drop the whole VBA set. Bounded at 64 parts; targets outside word/, relationship parts, the project itself, missing parts and parts the writer produces itself are skipped, never shadowed. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * DOCX: match VBA part names case-insensitively; keep colon names relative Two edge cases in carrying a VBA project's related parts: - The reader's word/ prefix check was case-sensitive, so a relationship to /WORD/vbaData.xml (the same part under OPC's case-insensitive part names, and found by Package::get) was skipped and lost on save. The directory is now matched case-insensitively and normalised to word/, the name the writer uses. - Stripping word/ from /word/sig:legacy.bin gave Target="sig:legacy.bin", which parses as a URI scheme rather than a package part. A target whose first segment has a colon is now written as "./sig:legacy.bin"; ordinary names keep the plain form Word already accepts.
