claude code agent 227 c4e0c3037c feat(git-sync): CommonJS build + §13.1 editor-ext idempotency gate (Phase A.2)
Make @docmost/git-sync natively consumable by the CommonJS server (and jest):
build to CommonJS (tsconfig module CommonJS, drop type:module, strip .js from
relative imports), and lazy-load the only ESM-only dep (marked) via the dynamic
Function('import()') trick (mirrors docmost-client.loader.ts) with a require()
fallback so vitest's evaluator works too. git-sync tests stay green (314 pass,
3 expected fail).

Add the §13.1 idempotency gate (apps/server .../git-sync-converter-gate.spec.ts):
13 editor-ext docs (paragraphs/headings, marks, links, bullet/ordered/task lists,
blockquote, callouts, code block, hr, table, nested mix) round-trip
content(editor-ext) -> convertProseMirrorToMarkdown -> markdownToProseMirror ->
TiptapTransformer.toYdoc/fromYdoc(tiptapExtensions) -> canonicalize and assert
docsCanonicallyEqual. All green => the vendored converter's docmost-schema is
schema-compatible with editor-ext (no node/mark/attr loss), which the plan §13.1
requires before Phase B. The one intrinsic markdown-image lossiness (width/height
/align can't ride plain ![](src)) is isolated in a KNOWN DIVERGENCE block, not
hidden. Server tsc clean.

/**
* Pure, network-free helpers for manipulating a ProseMirror/TipTap document
* tree by node id.
*
* A ProseMirror node here is a plain JSON object of the shape produced by
* Docmost: `{ type, attrs?, content?, text?, marks? }`. Children live in the
* `content` array; a node carries a stable id in `attrs.id`. Callouts and
* table cells hold their children in `content` just like any other block, so a
* single recursive walk reaches them all.
*
* Every exported function operates on a DEEP CLONE of the input document and
* returns the new document. The input doc and any `newNode`/`node` argument are
* never mutated. All functions are defensively null-safe: missing/!Array
* `content`, non-object nodes, and absent `attrs` are tolerated.
