Must-fix (REAL DATA LOSS):
- markdownToProseMirror is reused for COMMENT bodies (createComment/updateComment).
It unconditionally canonicalized, so a comment carrying a standalone footnote
definition ([^1]: text with no matching reference) had its whole footnotesList
stripped (referenceIds.length===0 -> stripFootnotesListsDeep) — the text
vanished. Fix: markdownToProseMirror no longer canonicalizes (content-preserving
primitive); a new markdownToProseMirrorCanonical wraps it for the PAGE write
paths (markdown import via importPageMarkdown, update_page markdown via
updatePageContentRealtime). Comment callers keep the non-canonicalizing
primitive. Updated the now-false header comment and added create/update-comment
inline notes. Added collaboration tests: comment path PRESERVES a reference-less
definition; page path still drops it AND still reorders real footnotes. Updated
the page-import canonicalization test to use the canonical variant.
Suggestions / architecture:
- #2: collapsed transforms.footnoteDefinition onto the shared
makeFootnoteDefinition factory (adds only the inner paragraph block id); kept
the dependency direction transforms -> footnote-authoring (no circular import,
mirror stays pure).
- #3: confirmed docmost_transform auto-canonicalization is documented (inline
comment, tool description, CHANGELOG) — no code change.
- #4: copyPageContent is a FULL-document write (replacePageContent of a
type:"doc"); added a defensive canonicalizeFootnotes pass (no-op on
already-canonical source).
- CHANGELOG entry refined to list the FULL-document write paths (incl.
copy_page_content) and to state canonicalization is NOT applied to comment
bodies.
