Make footnotes author-inline: the agent/tool inserts a footnote at its point
of use (anchor + text) and the numbering plus the bottom list are DERIVED
deterministically server-side. The agent has no access to footnotesList and
cannot desync — out-of-order lists, orphan definitions, and raw trailing
[^id] blocks become structurally impossible.
editor-ext:
- canonicalizeFootnotes(docJSON) -> docJSON: a pure, EditorView-free port of
footnoteSyncPlugin's end-state. Distinct reference ids in document order are
the source of truth; exactly one trailing footnotesList holds one definition
per referenced id in reference order (reusing the existing node or
synthesizing an empty one); orphans dropped; duplicate definitions resolved
deterministically (first wins, never lost); idempotent.
- Unit tests + a golden parity suite: on every editor-reachable steady state
the live footnoteSyncPlugin's JSON is a canonicalize no-op (byte-for-byte
parity), and the canonicalizer additionally repairs the out-of-order list a
non-editor write produces.
mcp:
- footnote-canonicalize.ts: behavioural mirror of the editor-ext canonicalizer
(the MCP package is intentionally decoupled from the editor barrel, like
footnote-lex/docmost-schema), plus footnoteContentKey for content dedup.
- Auto-canonicalize on EVERY write path: markdownToProseMirror (fixes import
ordering), update_page_json, and after every docmost_transform. Idempotent,
so it is a no-op when footnotes are already canonical.
- insert_footnote tool + insertInlineFootnote: anchor + markdown text -> a
mark-safe footnoteReference and a content-dedup'd definition; the list and
numbering are derived. Same-content footnotes reuse one number/definition.
- canonicalizeFootnotes + insertInlineFootnote exposed as docmost_transform
sandbox helpers.
Tests: editor-ext 157 green; MCP 325 green; server + client tsc clean.
