claude_code 882a6bb032 fix(editor): restore reading position only after the layout settles (#266)
Follow-up to the merged title-autofocus fix (#301). Confirmed via Chrome DevTools
on the live app: a residual reload jitter remained — the document renders
progressively (measured height 17729 -> 32185, collapsing mid-swap), and the
restore fired TOO EARLY (twice, at partial heights) because it only checked
"is the target reachable", not "has the layout settled". While the doc grew,
scroll-anchoring dragged the position and the second restore yanked it back
(the jitter), landing ~6000px off.

- restoreScrollPosition now polls the document height and restores ONCE the
  height has been stable for HEIGHT_STABLE_MS (400ms) AND the target is
  reachable; the MAX_RESTORE_WAIT_MS (5s) timeout is the only fallback that
  clamps. Removed the restoreStartRef shared budget; idempotency is now the
  `pollTimerRef !== null` guard (a running wait suppresses a second trigger).
- The two-trigger wiring (early on-mount for the offline path + post-swap) is
  unchanged; both call the now-settle-waiting, idempotent restore.
- A shadow simulation on the live page confirmed the new logic fires once,
  accurately (vs the old two-fire-plus-drift).
- Tests updated for the stable-height timing; (k) rewritten to pin the
  idempotency guard (mutation-verified); (d3) added for "waits until height
  stops changing".

Tradeoff: on progressively-rendering pages the position now appears once the
layout settles (~0.5-2s) in one smooth move, instead of an early-but-jittery,
often-inaccurate restore.

### Client structure
Vite SPA. Code is organized by feature under `apps/client/src/features/*` (mirrors the server domains: `page`, `space`, `comment`, `ai-chat`, `editor`, …). Conventions:
- **TanStack Query** for server state (one `queries/` file per feature), **Jotai** atoms for local/shared UI state, **Mantine 8** + CSS modules (`*.module.css`) + `postcss-preset-mantine` for UI.
- The editor is Tiptap; shared node/mark extensions live in `packages/editor-ext` and are imported by **both the client and the server** (collaboration, import/export) — editor schema changes often need to be made in `editor-ext`, not just the client. The ProseMirror↔Markdown converter and its Docmost schema mirror now live in a SINGLE package, `@docmost/prosemirror-markdown` (#293), consumed by both `mcp` and `git-sync` — do NOT reintroduce a per-package copy. `editor-ext` is the upstream source of the Tiptap schema; the package's `docmost-schema.ts` mirrors it and a serializer-contract test (`packages/prosemirror-markdown/test/serializer-contract.test.ts`) guards the boundary (every schema node must have a converter case), so a drift surfaces as a failing test rather than silent divergence.
- The editor is Tiptap; shared node/mark extensions live in `packages/editor-ext` and are imported by **both the client and the server** (collaboration, import/export) — editor schema changes often need to be made in `editor-ext`, not just the client. Note `packages/mcp` does *not* depend on `editor-ext`; it carries its own mirrored copy of the schema, so keep the two in sync manually when the document schema changes.
- API access goes through `apps/client/src/lib/api-client.ts` (axios). The `@` alias maps to `apps/client/src`.
- Runtime config is injected at build time by `vite.config.ts` via `define` (`APP_URL`, `COLLAB_URL`, `APP_VERSION`, …) — these come from the root `.env`, not from `import.meta.env`.

- The version string shown in the UI comes from `APP_VERSION` (CI/Docker) or `git describe --tags --always` (local), resolved in `vite.config.ts` — not from `package.json`.
- Server TS config is permissive (`noImplicitAny: false`, `strictNullChecks: false`, `no-explicit-any` lint disabled). Follow the existing relaxed style rather than tightening types broadly.
- Dependency versions are heavily pinned via `pnpm.overrides` and `pnpm.patchedDependencies` (`scimmy`, `yjs`) in the root `package.json`. Don't bump pinned/patched deps casually; the patches and overrides exist for compatibility/security reasons.
- **Adding/renaming/removing an MCP tool requires updating `SERVER_INSTRUCTIONS`** in `packages/mcp/src/index.ts` — the intent-routing guide MCP clients receive on initialize. This applies both to inline `server.registerTool(...)` calls in `index.ts` and to specs in `packages/mcp/src/tool-specs.ts`. Enforced by `packages/mcp/test/unit/server-instructions.test.mjs`, which fails when a registered tool is not mentioned in the guide (deliberate opt-outs go into its `EXCEPTIONS` list). `packages/mcp/build/` is gitignored and rebuilt in CI/Docker via `pnpm build` (same convention as `git-sync`/`prosemirror-markdown`) — never commit it; rebuild locally after editing to run the tests.

Сначала прочитай весь текст и оцени его как историю целиком. Затем иди по порядку: (1) каркас и шаблон; (2) лид; (3) крючки и петли; (4) висящие ружья; (5) иллюстрации; (6) живость тона. Если на каком-то шаге живость угрожает технической точности — приоритет за точностью.
═══ КАК ОСТАВЛЯТЬ ЗАМЕЧАНИЯ ═══
Ты не редактируешь текст напрямую и не переписываешь его за автора. Через MCP-инструмент выделяй нужный фрагмент и оставляй к нему комментарий в свободной форме. Объясняй не только «что», но и «зачем» — какой эффект на читателя это даст. Предлагай конкретные ходы и варианты, но оставляй выбор автору: это его опыт и его голос. Если среди вариантов есть один готовый текст (например, новая формулировка лида), можешь приложить его к комментарию как предложение-замену (параметр `suggestedText`: точный новый текст взамен выделенного фрагмента, без разметки; фрагмент должен встречаться в тексте ровно один раз, иначе расширь выделение) — кнопка ничего не навязывает, автор волен не применять. Комментируй то, что усилит историю, а не каждую мелочь.

*
* A boundary is the end of a maximal `\n{2,}` run that is followed by at least

* boundary yet: under append-only growth it may still gain more newlines, and
* cutting there would move the boundary on the next call.
*
* CRITICAL INVARIANT (load-bearing for StreamingPlainText's memoization): for
* APPEND-ONLY growth of `text`, every chunk except the LAST is byte-identical
* between successive calls — previously-emitted boundaries never move. Proof
* sketch: appending never modifies existing characters, so (a) an existing
* boundary's newline run and its following character are untouched and the
* boundary persists at the same offset; (b) no NEW boundary can appear strictly
* inside the old text, because a `\n{2,}` run followed by a character entirely
* within the old text would already have been a boundary. New boundaries can
* only materialize at or after the old text's end, i.e. inside the last chunk.
*
* CRLF is deliberately NOT a boundary: supporting `(?:\r?\n){2,}` would BREAK
* the invariant above — a lone trailing `\r` is not a boundary, but a later-
* appended `\n` would merge with it into a new separator unit and retroactively
* create a boundary INSIDE previously-emitted text, moving old chunk edges.
* With `\n`-only runs, appended characters can never extend a run that is
* already followed by a non-`\n` character, so old boundaries are immutable.
* CRLF blank lines therefore intentionally stay inside one chunk: correctness/
* losslessness are unaffected, only chunk granularity for CRLF input (LLM

* their restored reading position (and threw their scroll to 0 if they were
* scrolling at that moment). Pinning a min-height on the swap wrapper keeps the
* document tall through the swap so the scroll position simply survives (#266).
* `reservedHeight === null` means no reservation is active.
*
* The capture is intentionally a CALLBACK the page editor invokes, NOT something
* this hook derives by watching `showStatic`. The height MUST be read
* synchronously while the static content is still mounted (full natural height),
* right before the flip to the live branch. By the time any post-transition
* effect here could run, `showStatic` is already false and the wrapper shows the
* live/collapsed content, so `offsetHeight` would be wrong. So page-editor calls
* `captureReservation(wrapper.offsetHeight)` inside its collab-sync effect,
* before `setShowStatic(false)`, preserving that exact timing.
*
* @param showStatic whether the static (cached) content is still shown.
* @param menuContainerRef the live-branch content container. It is a descendant
* of the swap wrapper inside the live branch, so its `scrollHeight` is the live
* content height (not inflated by the ancestor min-height reservation).
