Real root cause of the silent MCP edit loss: the web editor always opens the
collaboration document by the page UUID (`page.${page.id}`), but the MCP
opened it by the agent-supplied id — usually a slugId — so `page.${pageId}`
became `page.<slugId>`. For one DB page that is TWO independent Yjs documents;
both persist to the same `pages` row (findById/updatePage resolve id or
slugId), so the human tab's debounced store overwrites the agent edit
(last-store-wins) — gone after reload, never shown live. The slugId doc also
made the server's transclusion sync + embedding reindex throw Postgres 22P02.
Fix:
- MCP (primary): resolvePageId(pageId) returns the canonical UUID — a UUID
short-circuits with no network call, a slugId resolves once via getPageRaw
and is cached both ways. Every collab-write path (mutatePageContent /
updatePageContentRealtime / replacePageContent and the mutate/replace/
unlocked seams) now opens by the resolved UUID, so the MCP and the editor
share ONE Yjs doc. replaceImage's whole-operation page lock also keys on the
UUID so it serializes against the other (now-UUID-keyed) writes.
- Server (defense + kills the 22P02 noise): onStoreDocument passes the resolved
page.id — not the raw doc-name id — to syncTransclusion, the embedding queue,
the mention-notification job, addContributors, and the in-tx history read.
Content store and the empty-guard are untouched.
Tests: a new MCP test stands up a real Hocuspocus server and asserts a slugId
input opens `page.<uuid>` (never `page.<slugId>`), with UUID short-circuit and
single-resolve caching; the server spec asserts the side-effects receive the
UUID for a `page.<slugId>` doc. closes#260

Must-fix:
- REAL BUG: insertInlineFootnote could splice a footnoteReference (inline atom)
into a codeBlock or an existing footnoteDefinition, persisting a schema-invalid
doc (insert_footnote skips validateDocStructure). Now the search is bounded to
the BODY (before the first footnotesList) and the insertNodesAfterAnchor core
refuses textblocks that can't hold the atom (codeBlock); when the only match is
in such a place the insert returns inserted:false and the write aborts cleanly.
Reachable via docmost_transform too. Added codeBlock / definition / fall-through
tests.
- Fixed the deepEqualJson doc comment in both copies: arrays are order-SENSITIVE
(correctness depends on it), only object keys are order-insensitive.
- README.ru.md MCP tool count 38 -> 39 (lines 36/47/63), matching README.md/AGENTS.
- CHANGELOG [Unreleased] Added entry for insert_footnote + server-side footnote
canonicalization on non-editor write paths (#228).
Suggestions:
- canonicalize step 5/7 now strips footnotesList at ANY depth (both copies), so a
schema-valid list nested in a callout/blockquote can't leave duplicate defs.
- Exclude the test-only footnote-corpus.ts fixture from the editor-ext build
(tsconfig), so it no longer ships in dist/.
- Removed the duplicate manual canonicalize cases from the MCP unit test (the
shared corpus covers them via full deepEqual); kept idempotence + immutability.
- insertInlineFootnote dedup key now keys off the inline array directly
(footnoteContentKey({ content: inline })) instead of a throwaway node.
Tests / architecture:
- New client-wrapper test (#9): overrides a small mutatePage seam to assert the
not-found path throws and persists NOTHING, and the success path shapes
footnoteId/reused/message/verify and writes the right content. Fixed the
misleading comment in footnote-write.test.mjs.
- B: cross-copy corpus parity guard test (loads both corpora, asserts deep-equal)
so a typo in one copy can't pass both suites green.
- A: declined — the full-vs-fragment decision lives at the call site, so a
prepareDocForPersist wrapper would be a bare alias for canonicalizeFootnotes;
kept the existing per-call-site comments instead.
