agent_coder 044daab357 feat(git-sync): двусторонний Docmost↔git синк на унифицированном конвертере (#359)
Схлопнутая дельта feat/git-sync-2 поверх актуального develop (3085ec1b).

Почему squash, а не буквальный rebase: в ветке 113 коммитов, из которых
develop уже впитал ~80 в курированном виде при унификации конвертера
(#326/#293) — но не patch-identical, поэтому они не отваливаются сами; а
коммит, УДАЛЯЮЩИЙ вендоренную копию конвертера, апстримный и в replay-набор
не входит, так что наивный replay заново добавил бы вендоренные копии.
Поэтому корректный итог — «develop + чистая net-дельта ветки», сведённая
3-way мержом (merge-base 5336f06d).

Net-дельта: серверный git-sync модуль (GitSyncModule/orchestrator/HTTP),
движок git-sync (layout/reconcile/pull/push/stabilize + QA), два фикса
round-trip/data-loss конвертера поверх УНИФИЦИРОВАННОГО
@docmost/prosemirror-markdown (вендоренной копии больше нет — git-sync
целиком на унифицированном конвертере, поведение унифицированного принято
за эталон), e2e-скрипты, доки.

Конфликты (4) слиты объединением: main.ts (метрики + GitHttpService),
apps/server/package.json (pretest-суперсет; moduleNameMapper: git-sync→src
и .js-strip оставлены, а bare-specifier @docmost/prosemirror-markdown→src
УБРАН — серверный jest выровнен на develop-подход #345 со сборённым
пакетом), .env.example (метрики + GIT_SYNC блоки), AGENTS.md (строки про
пакеты; устаревшая заметка про «три hand-synced копии схемы» в git-sync
поправлена — схема теперь только в @docmost/prosemirror-markdown).

name: Nightly property fuzz
# The daily heavy property run for the ProseMirror<->Markdown converter
# (packages/prosemirror-markdown). The PR/CI test run keeps NUM_RUNS modest to
# stay under budget; this cron cranks up total coverage with random seeds to hunt
# for deeper round-trip counterexamples than a fixed-seed PR run can reach.
#
# WHY SHARDING: a single mega-run (~10000 fast-check runs) OOMs the vitest worker
# (empirically ~1625 runs -> "JS heap out of memory", ~2GB) because heap
# accumulates across the whole property run in one process. Instead this job runs
# SHARDS fresh vitest processes, each a MODERATE per-shard count with a DISTINCT
# derived seed, so total coverage ~= SHARDS x PER_SHARD_NUM_RUNS across processes
# that never accumulate heap. On the first failing shard we stop and keep that
# shard's output for triage.
#
# Counterexample -> fixture workflow: when a shard fails, fast-check prints the
# SHRUNK minimal counterexample plus the reproducing seed. This job files a Gitea
# issue containing that seed + counterexample ONLY when the output actually holds
# a fast-check counterexample; an infra failure (OOM/tsc/install, no
# counterexample) is filed under a DISTINCT title so it can never poison the
# counterexample dedup. A human then commits the shrunk doc as a PERMANENT fixture
# under packages/prosemirror-markdown/test/fixtures/counterexamples/ with a case in
# counterexamples.test.ts, and FIXES the converter (never weakens a property to
# hide the bug). See packages/prosemirror-markdown/README.md.

### Git-sync (native two-way Docmost ↔ git Markdown sync)
`integrations/git-sync/` (`GitSyncModule`) + the vendored pure engine in `packages/git-sync`. Off by default; gated by the `GIT_SYNC_ENABLED` master switch (and `GIT_SYNC_SERVICE_USER_ID`, the account git-originated writes are attributed to). Per-space opt-in via `space.settings.gitSync.enabled`, with a second per-space toggle `space.settings.gitSync.autoMergeConflicts` that changes PUSH behavior for a still-conflicted page (one carrying `<<<<<<<`/`>>>>>>>` markers): **off (the safe default)** records a per-page failure and holds the refs so the user resolves the git conflict first (markers never reach Docmost); **on** strips the marker lines and pushes both sides' content. Each enabled space gets an on-disk working "vault" repo; the `GitSyncOrchestrator` runs a debounced + poll-backstop reconcile cycle (PULL Docmost→vault, PUSH vault→Docmost) under a per-space Redis leader lock + in-process mutex (`SpaceLockService`). Writes go through the collaboration layer (so concurrent human edits aren't clobbered) and are stamped `lastUpdatedSource = 'git-sync'` for the listener loop-guard. The in-process `setInterval` orchestration + best-effort lock (no fencing tokens) is a known multi-replica limitation — BullMQ + fencing is the documented future direction.
- **`/git` smart-HTTP host** (`integrations/git-sync/http/`, gated additionally by `GIT_SYNC_HTTP_ENABLED`, which defaults to `GIT_SYNC_ENABLED`): a raw root-mounted Fastify route `/git/<spaceId>.git/...` (registered in `main.ts`, NOT under `/api`) that bridges `git clone`/`fetch`/`push` to `git http-backend`. It authenticates HTTP Basic against `AuthService` (throttled by a `FailedLoginLimiter` mirroring the `/mcp` path), authorizes via `SpaceAbilityFactory` (read = fetch, Manage = push), and gates existence so a non-member gets the SAME 404 as a missing/sync-disabled space (never 403 — that would leak space existence). A push runs the receive-pack under the space lock, then a reconcile cycle.
- **Schema mirror:** git-sync no longer carries its own schema copy — it consumes the Docmost schema mirror from `@docmost/prosemirror-markdown` (#293), which is itself mirrored from the canonical `editor-ext` and guarded by the serializer-contract test. There is no longer a per-package hand-synced copy to keep in lockstep.

### Reverse proxy: SSE streaming paths
The AI agent streams its answers over Server-Sent Events. These endpoints produce a
long-lived `text/event-stream` response and **must bypass response buffering AND response
compression** at every proxy in front of the app:
- `POST /api/ai-chat/stream` — the live agent turn stream
- `GET /api/ai-chat/runs/<chatId>/stream` — attach/resume of a detached agent run
(`AI_CHAT_RESUMABLE_STREAM`)
- `POST /api/shares/ai/stream` — the anonymous public-share assistant
A buffering or compressing proxy does not break these with an error — it silently ruins them:
the request hangs in `pending`, tokens stop streaming and arrive in one burst when the turn
ends, or a reloaded tab falls back to coarse polling. The tell in DevTools is a
`Content-Encoding: gzip/zstd` response header on a `text/event-stream` response.
The server already sends `X-Accel-Buffering: no` (honored by nginx unless ignored), but
compression middleware is applied by proxy configuration, not headers:
- **nginx** — `proxy_buffering off; proxy_cache off; gzip off;` for these locations, e.g.
`location ~ ^/api/(ai-chat/(stream$|runs/.+/stream$)|shares/ai/) { ... }`
- **Traefik** — route these paths through a dedicated router **without** the `compress`
middleware (a `compress` middleware buffers SSE frames until the response closes), e.g.
``PathPrefix(`/api/ai-chat/stream`) || PathPrefix(`/api/ai-chat/runs/`)``. Belt-and-braces:
`traefik.http.middlewares.<name>.compress.excludedcontenttypes: text/event-stream`.

### Reverse proxy: SSE-стриминговые пути
AI-агент стримит ответы через Server-Sent Events. Эти эндпоинты отдают долгоживущий

- `POST /api/ai-chat/stream` — живой стрим хода агента

(`AI_CHAT_RESUMABLE_STREAM`)
- `POST /api/shares/ai/stream` — анонимный ассистент публичных шар
Буферизующий или сжимающий прокси не ломает эти пути с ошибкой — он тихо их портит:
запрос висит в `pending`, токены не стримятся и вываливаются одним куском в конце хода,
а перезагруженная вкладка падает в грубый поллинг. Диагностический признак в DevTools —
заголовок `Content-Encoding: gzip/zstd` на ответе с `text/event-stream`.

например `location ~ ^/api/(ai-chat/(stream$|runs/.+/stream$)|shares/ai/) { ... }`
- **Traefik** — вести эти пути через отдельный роутер **без** `compress`-мидлвари
(compress буферизует SSE-кадры до закрытия ответа), например
``PathPrefix(`/api/ai-chat/stream`) || PathPrefix(`/api/ai-chat/runs/`)``. Для надёжности:
`traefik.http.middlewares.<name>.compress.excludedcontenttypes: text/event-stream`.

it is BINDING — a floor you MUST reach. Spend it in full even past the point - Decide which languages it makes sense to search in (see below).
where the topic feels covered (see BUDGET REMAINDER PROTOCOL below).
- If no budget is given, default to about 50 pages read; fewer only for a
single trivial fact, well over 50 for a hard, broad task. Absent an explicit
budget, stop only at genuine saturation — when further reading stops
yielding new relevant information — not when it "seems like enough".
- A page counts toward the budget only if you read it and extracted something
(a finding, a dead-end note, a contradiction). Skimming a snippet does not
count. Re-opening the same page does not count twice.
- Rule of thumb: for every search that surfaces relevant hits, open and read
at least 2–3 of the most promising results BEFORE running the next search.
Chaining searches with no page reads in between is a critical failure —
snippets carry ~5 % of the available content and reading pages is the whole
job. If you catch yourself doing it, stop and go read what you already
found.
BUDGET REMAINDER PROTOCOL. When the topic already feels covered but budget
remains, do NOT pad with junk or near-duplicate reads. Spend the remainder in
this priority order:
1. ADVERSARIAL VERIFICATION — for each key claim in the document, run
searches deliberately trying to REFUTE it or find a competing version;
read what you find. Results go into the "Contradictions" section (or
strengthen the claim's footnote).
2. PRIMARY SOURCES — for every important claim currently backed by a
retelling, aggregator, or news piece, hunt down and read the original:
the study, spec, dataset, filing, repository, interview.
3. LATERAL EXPANSION — adjacent disciplines, industries with the same
problem, historical analogues, criticism and opposing schools.
Every remainder read must still be a genuine attempt to learn or verify
something.
═══════════════════════════════════════════════ ═══════════════════════════════════════════════

report itself, live, from the first minute. - Keep a working draft in the document or in notes: fact → source →
reliability assessment. Update the structure as you go.
SETUP. Create/claim the document at the VERY START, before any searches.
Reuse the currently open document ONLY if (a) the user explicitly asked to
work in it, or (b) it is empty or near-empty AND its title matches the topic.
Otherwise create a new one.
Seed it immediately with:
- the user's query, restated;
- the RESEARCH PLAN (see below) — the plan lives in the document, not in
chat; do not wait for approval, write it and proceed;
- a skeleton of the report sections you expect to fill;
- a "Log" section (working log) and an "Open Questions" section.
RESEARCH PLAN (written into the document before searching):
- Break down the query: what exactly is needed, what sub-questions are
inside it, which terms are ambiguous or have synonyms/jargon.
- 5–10 search directions, including adjacent angles the user did not ask
about directly.
- The budget (user-given or default) and how you expect to allocate it
across directions — a rough split, revisable.
- Which languages to search in.
THE LOG. In the "Log" section keep a numbered list of pages read:
`N. [query →] source — what I took / empty / contradiction`. One line each.
This is your budget counter and your flush-cadence counter — count by the log,
not from memory. Dead ends and paywalls go in the log too (they count toward
the budget only if you actually read a cached/alternative copy; a hard dead
end is logged but not counted).
FLUSH CADENCE — HARD RULE. Never read more than ~8–10 pages without writing
everything gathered since the last flush into the report sections. Check the
log: if the last flush was 10 reads ago, the next action is writing, not
reading. Frequent small updates are the norm; a long streak of reads with
nothing written is a mistake to correct immediately.
CONTEXT DISCIPLINE. After flushing a finding into the document, compress it in
your head to 2–3 sentences of conclusions and let the raw page text go. Do not
carry full page contents forward in context. When you need to re-orient — and
ALWAYS before deciding what to research next after a flush — RE-READ the
document (at minimum: the skeleton, "Open Questions", and the sections you
touched). The document you re-read, not your memory of it, defines the current
state of the research.

ones. Flush per the cadence above.
═══════════════════════════════════════════════
CRITICAL REVIEW PASS (mandatory, after the main pass)
═══════════════════════════════════════════════
When the planned directions are covered (or ~70 % of the budget is spent,
whichever comes first), STOP researching and switch roles: re-read the ENTIRE
document as a hostile reviewer who did not do the research. Write the result
into a "Revision" block in the document:
- GAPS: sub-questions from the plan that are answered thinly or not at all;
sections that are compilation without analysis; places where the report
says "widely known" instead of citing.
- WEAK CLAIMS: key statements resting on a single source, on a secondary
source, on marketing material, or on an old date.
- CONTRADICTIONS: places where the document disagrees with itself.
- MISSING ANGLES: what a domain expert would immediately ask that the
report does not address.
Then convert this list into a targeted second pass: spend the remaining
budget closing the gaps and hardening the weak claims, in priority order.
If budget remains after that, apply the BUDGET REMAINDER PROTOCOL. Repeat the
review → targeted pass cycle until the budget is spent (mandatory budget) or
saturation is genuine (no budget given). A report that got only one linear
pass and no revision is not finished.

LANGUAGE AND TERMINOLOGY OF THE REPORT
═══════════════════════════════════════════════
The report is in English. Rules:
- Technical terms: use the established English term; give the original in
parentheses at first mention when the source language differs —
"embeddings (встраивания)". If no settled English term exists, keep the
original and gloss it once.
- Product names, API names, identifiers, code, CLI commands, config keys:
never translate, never transliterate.
- Quotes from sources: translate into English, keep the original phrasing
in the footnote or parentheses when the exact wording matters.
- Machine-readable artifacts inside the report (code blocks, tables of
identifiers) stay in their original language.

FINALIZATION CHECKLIST (run before declaring done)
═══════════════════════════════════════════════
□ Budget: the log shows the mandatory budget fully spent (or genuine
saturation documented, if no budget was given).
□ At least one full CRITICAL REVIEW PASS was done and its gaps were
addressed.
□ Every non-trivial claim has an inline `^[...]` footnote; no claim rests
solely on a snippet or a tier-6 source.
□ Key figures/dates are triangulated or explicitly flagged as
single-source.
□ The direct answer at the top matches the body of the report.
□ "Unknown" is honestly filled — not empty by omission.
□ Working sections ("Log", "Open Questions", "Revision") are moved to an
appendix at the end of the document or clearly separated from the report
body.
Be honest about gaps. If you couldn't find something, say so — don't disguise
a guess as a fact.

THE BUDGET: PAGES READ, NOT SEARCHES STEP 0. PLAN (always do this first)
═══════════════════════════════════════════════ ═══════════════════════════════════════════════
The unit of research work is a PAGE READ IN FULL — opening a source with the Before searching for anything, draft and show a research plan:
page-reading/extraction tool and actually reading it. Search queries are free - Break down the query: what exactly is needed, what sub-questions are
and unlimited: they are navigation, not research. A search result snippet is a inside it, which terms are ambiguous or have synonyms/jargon.

- Set a "research budget" — roughly how many searches the task's complexity

it is BINDING — a floor you MUST reach. Spend it in full even past the point - Decide which languages it makes sense to search in (see below).
where the topic feels covered (see BUDGET REMAINDER PROTOCOL below).
- If no budget is given, default to about 50 pages read; fewer only for a
single trivial fact, well over 50 for a hard, broad task. Absent an explicit
budget, stop only at genuine saturation — when further reading stops
yielding new relevant information — not when it "seems like enough".
- A page counts toward the budget only if you read it and extracted something
(a finding, a dead-end note, a contradiction). Skimming a snippet does not
count. Re-opening the same page does not count twice.
- Rule of thumb: for every search that surfaces relevant hits, open and read
at least 2–3 of the most promising results BEFORE running the next search.
Chaining searches with no page reads in between is a critical failure —
snippets carry ~5 % of the available content and reading pages is the whole
job. If you catch yourself doing it, stop and go read what you already
found.
BUDGET REMAINDER PROTOCOL. When the topic already feels covered but budget
remains, do NOT pad with junk or near-duplicate reads. Spend the remainder in
this priority order:
1. ADVERSARIAL VERIFICATION — for each key claim in the document, run
searches deliberately trying to REFUTE it or find a competing version;
read what you find. Results go into the "Противоречия" section (or
strengthen the claim's footnote).
2. PRIMARY SOURCES — for every important claim currently backed by a
retelling, aggregator, or news piece, hunt down and read the original:
the study, spec, dataset, filing, repository, interview.
3. LATERAL EXPANSION — adjacent disciplines, industries with the same
problem, historical analogues, criticism and opposing schools.
Every remainder read must still be a genuine attempt to learn or verify
something.

reliability assessment. Update the structure as you go.
SETUP. Create/claim the document at the VERY START, before any searches.
Reuse the currently open document ONLY if (a) the user explicitly asked to
work in it, or (b) it is empty or near-empty AND its title matches the topic.
Otherwise create a new one.
Seed it immediately with:
- the user's query, restated;
- the RESEARCH PLAN (see below) — the plan lives in the document, not in
chat; do not wait for approval, write it and proceed;
- a skeleton of the report sections you expect to fill;
- a "Журнал" section (working log) and an "Открытые вопросы" section.
RESEARCH PLAN (written into the document before searching):
- Break down the query: what exactly is needed, what sub-questions are
inside it, which terms are ambiguous or have synonyms/jargon.
- 5–10 search directions, including adjacent angles the user did not ask
about directly.
- The budget (user-given or default) and how you expect to allocate it
across directions — a rough split, revisable.
- Which languages to search in.
THE LOG. In the "Журнал" section keep a numbered list of pages read:
`N. [запрос →] источник — что взял / пусто / противоречие`. One line each.
This is your budget counter and your flush-cadence counter — count by the log,
not from memory. Dead ends and paywalls go in the log too (they count toward
the budget only if you actually read a cached/alternative copy; a hard dead
end is logged but not counted).
FLUSH CADENCE — HARD RULE. Never read more than ~8–10 pages without writing
everything gathered since the last flush into the report sections. Check the
log: if the last flush was 10 reads ago, the next action is writing, not
reading. Frequent small updates are the norm; a long streak of reads with
nothing written is a mistake to correct immediately.
CONTEXT DISCIPLINE. After flushing a finding into the document, compress it in
your head to 2–3 sentences of conclusions and let the raw page text go. Do not
carry full page contents forward in context. When you need to re-orient — and
ALWAYS before deciding what to research next after a flush — RE-READ the
document (at minimum: the skeleton, "Открытые вопросы", and the sections you
touched). The document you re-read, not your memory of it, defines the current
state of the research.

ones. Flush per the cadence above.
═══════════════════════════════════════════════
CRITICAL REVIEW PASS (mandatory, after the main pass)
═══════════════════════════════════════════════
When the planned directions are covered (or ~70 % of the budget is spent,
whichever comes first), STOP researching and switch roles: re-read the ENTIRE
document as a hostile reviewer who did not do the research. Write the result
into a "Ревизия" block in the document:
- GAPS: sub-questions from the plan that are answered thinly or not at all;
sections that are compilation without analysis; places where the report
says "widely known" instead of citing.
- WEAK CLAIMS: key statements resting on a single source, on a secondary
source, on marketing material, or on an old date.
- CONTRADICTIONS: places where the document disagrees with itself.
- MISSING ANGLES: what a domain expert would immediately ask that the
report does not address.
Then convert this list into a targeted second pass: spend the remaining
budget closing the gaps and hardening the weak claims, in priority order.
If budget remains after that, apply the BUDGET REMAINDER PROTOCOL. Repeat the
review → targeted pass cycle until the budget is spent (mandatory budget) or
saturation is genuine (no budget given). A report that got only one linear
pass and no revision is not finished.

* effect then holds the latch via `if (!run) return` until the CURRENT turn's run
* is fetched fresh. If that refetch instead ERRORS permanently, `run` stays null,
* its status-keyed refetchInterval is off, and nothing would ever observe a
* terminal run freezing the view with the observer merge suppressed. This
* safety-net cures ONLY that genuine permanent-null-freeze.
*
* All four must hold:
* - `stoppingRun`: we actually requested a stop (otherwise nothing to release);
* - `!isLocalStreaming`: this tab is NOT the local streamer (same reason as
* {@link shouldClearStoppingLatch});
* - `runQueryFailed`: the run query is in its error state (TanStack Query v5 with
* retry:false isError);
* - `!isRunActive(run)`: the observed `run` is NOT an active (pending/running)
* held run. This is the F7 gate. In TanStack Query v5 the query's `data` is
* RETAINED on error, so `runQueryFailed` can be true while `run` is STILL an
* ACTIVE run (a single transient GET-run failure in the window between Stop and
* settle). Without this gate a transient error would release the latch early
* re-opening the observer merge and flashing the growing detached run over the
* frozen row (exactly the F4 flash). Gating on the run NOT being active means we
* only ever cure the permanent-null-freeze (`run === null`, so
* `isRunActive(null)` is false), never release against an active run.
*
* (A terminal `run` also satisfies `!isRunActive(run)`; clearing then is harmless
* the terminal effect's {@link shouldClearStoppingLatch} already clears the
* latch for a terminal run, so this only ever agrees with it, never conflicts.)
*
* INVARIANT (do not break): clearing the latch on the `run === null` branch is safe
* ONLY because the run query's `refetchInterval` (see {@link runPollInterval}) stops
* polling when the data is empty so after we clear on null+error there is no
* subsequent auto-poll that could return a still-active detached run and re-open the
* merge. If `refetchInterval` is ever changed to keep polling on `run === null`/on
* error, this null-branch clear would re-open the F7 flash through the null path.
* Do not change the run query's refetchInterval without re-checking this path.

* (closing the tab within the debounce window, ~3-18s) therefore left the edit

* the STALE/empty DB body to the vault (the reported "59-byte frontmatter-only"
* data loss). Running the already-scheduled store now closes that window.
*
* Gated tightly so it never adds a redundant write: only on the LAST disconnect
* (`clientsCount === 0`), only for a fully-loaded doc, and only when a store is
* actually pending (`isDebounced`). `executeNow` runs the SAME payload Hocuspocus

* server jest config `moduleNameMapper`s `@docmost/git-sync` to its TS SOURCE and
* strips the ESM `.js` import suffixes. ts-jest then type-checks that source under
* the server's (looser) tsconfig and trips a benign narrowing; the global
* `isolatedModules: true` on the ts-jest transform (apps/server/package.json)
* makes it transpile-only so this spec loads. Full type-checking of the package
* is still enforced by its own `tsc`/vitest gates and the server `tsc --noEmit`.
*
* §13.1 IDEMPOTENCY GATE the blocking gate for git-sync Phase B.
*
* Proves the `@docmost/git-sync` pure converter is schema-compatible
* with the server's REAL editor-ext document schema: a representative corpus of
* editor-ext ProseMirror documents must survive a full round trip through the
* actual server write path without losing any node / mark / attribute.
*
* Pipeline per document (issue #194 §13.1):
* 1. md = convertProseMirrorToMarkdown(content) // git-sync export
* 2. doc = await markdownToProseMirror(md) // git-sync import
* 3. push `doc` through the REAL editor-ext Yjs write path the server uses:
* ydoc = TiptapTransformer.toYdoc(doc, 'default', tiptapExtensions)
* normalized = TiptapTransformer.fromYdoc(ydoc, 'default')
* This is exactly what PersistenceExtension does on store
* (apps/server/src/collaboration/extensions/persistence.extension.ts:96/115)
* with the same `tiptapExtensions` (collaboration.util.ts) and the same

* validation that runs on a git-sync write (issue #194 §3.3).
* 4. assert docsCanonicallyEqual(canon(original), canon(normalized)) === true

* Any node / mark / attr that editor-ext drops (because the git-sync
* docmost-schema named it differently, or declares a different default) makes

/**
* Pure block-level THREE-WAY merge planner (diff3) over arrays of opaque block

*
* - a block only the human changed (live != base, git == base) -> keep LIVE
* - a block only git changed (git != base, live == base) -> take GIT
* - a block both sides changed (a real conflict) -> GIT wins
* - inserts/deletes from either side are preserved when unambiguous
*
* Content-agnostic: it works on string keys and returns the merged block order as
* picks ({ src: 'live'|'target', index }) the caller (the Yjs applier)
* materializes them so the whole algorithm is unit-testable on plain arrays.
*
* Algorithm: anchor on base blocks present (unchanged) in BOTH live and target
* (their LCS-with-base intersection). Between consecutive anchors lies one region
* the human and/or git rewrote; resolve each region three-way. Stable anchor
* blocks are emitted from LIVE so the applier keeps the existing Yjs block
* instances (and the human's in-flight edits) in place.

* ROOT CAUSE (confirmed in-process against the real failing page): the LIVE Yjs
* document materializes the editor-schema default `indent: 0` on every
* paragraph/heading (and on the paragraph inside every list item, callout, and
* table cell), but a body re-imported from git parsed from clean markdown
* carries NO indent attribute. So every live block's comparison key differed from

* NOTHING, and the trailing unit that git's export already contained (but the
* merge could not match against the byte-identical live tail) was re-appended
* each cycle. Each grown export then diverged from the last-pushed base by one
* more unit a self-sustaining loop.
*
* The fix normalizes the materialized default (`indent: 0`) out of the block key
* (the schema-derived `serializeXmlNode` normalization in yjs-body-merge.ts drops
* every attr equal to its ProseMirror-schema default; `indent: 0` is one such),

*
* Strategy: diff the two documents at TOP-LEVEL BLOCK granularity (an LCS over a

* insert/delete operations. Blocks that are byte-identical on both sides are
* left UNTOUCHED in the live doc so a human editing one paragraph is unaffected
* when git changes a different paragraph, and an unchanged re-sync is a complete
* no-op (zero Yjs operations). Yjs then CRDT-merges the minimal ops with any
* concurrent edits.
*
* Merge mode: a THREE-WAY merge (live vs incoming vs base) runs whenever the
* engine plumbs the last-synced base (`baseMarkdown` from refs/docmost/last-pushed)
* which it now does end-to-end so a block both sides changed is a genuine
* conflict resolved deterministically (git wins that block; the prior state is

* arriving from git is parsed from clean markdown, which carries no block ids
* (`markdownToProseMirror` materializes `id: null`, which the Yjs transform then
* drops). If `id` were part of the key, an UNCHANGED live block (id "abc123")
* would never match the SAME block coming from git (no id), so the three-way
* merge's LCS could not anchor on it. The merge would then treat every live
* block as deleted-and-reinserted and, when an incoming block has no matching
* anchor (e.g. content inserted at the very TOP of the page), RE-ADD a copy of
* it on every sync cycle a non-convergent, unbounded duplication loop

* resulting null/absent element attrs are then DROPPED by `y-prosemirror`'s

* applies zero ops. Genuinely non-default values (a real `indent: 2`, an

* `schema-editor-ext-contract.test.ts` compares only node/mark TYPE NAMES, so a

* silently dropped on every git-sync round trip. That is a repeatedly-hit

*
* This test closes the attribute gap MECHANICALLY: it builds the real canonical

* uses) and the git-sync mirror schema, then asserts that for every node/mark the
* two schemas share, their ATTRIBUTE-KEY sets are equal minus a committed

* fails CI loudly instead of losing data in production.
*
* WHY THIS ISN'T THE "fragile attribute compare" the sibling name-level contract
* (`packages/git-sync/test/schema-editor-ext-contract.test.ts`) deferred: that
* concern was about comparing raw extension CONFIGS, where editor-ext spreads
* global attributes (textAlign, id, ) across separate extensions and StarterKit
* contributes types the mirror gets elsewhere. We instead compare the RESOLVED
* ProseMirror `Schema` objects `getSchema()` has already merged every
* addGlobalAttributes spread into concrete per-node attrs on both sides so the

/**
* D1 a HUNG MCP handshake must not POISON the per-workspace build cache.
*
* THE BUG (production hang): `createMCPClient` (inside the private `connect`) is
* NOT bounded by a timeout and like @ai-sdk/mcp's tool calls its promise does
* NOT settle on abort. A transient network blip mid-handshake made connect hang
* FOREVER. Because getOrBuildEntry caches the build PROMISE, that never-settling
* connect wedged EVERY later turn for the workspace (each awaited the same pending
* build) step_count stuck at 0, run row leaking 'running', chat 409ing forever.
*
* THE FIX: `connectWithTimeout` races `connect` against a SETTLING timeout
* (CONNECT_TIMEOUT_MS). On timeout it REJECTS, so buildEntry catches it, records
* the server `ok:false`, and the build COMPLETES with that server skipped the
* cache is never poisoned and a subsequent `toolsFor` returns instead of hanging.
*
* REACHABILITY NOTE: the smallest network-free path that exercises the fix is to
* spy on the private `connect` (the same harness the namespacing spec uses)
* `connectWithTimeout` wraps exactly that call, so a never-resolving `connect`
* models a never-settling `createMCPClient` precisely, without DNS/sockets.
*
* Fake timers prove the timeout fires WITHOUT real waiting.

* SQL-builder unit test for the git-sync provenance stamp on PageRepo's

* it into the recursive-subtree `UPDATE pages SET ...` via
* `...(lastUpdatedSource ? { lastUpdatedSource } : {})`. The change-listener
* loop-guard reads `last_updated_source = 'git-sync'` to recognize git-sync's own
* writes and skip the echo cycle; this test guards that the stamp is present when
* the arg is supplied and ABSENT when it is omitted (an ordinary user delete must
* not clobber the column).
*
* Harness: the same compile-only Kysely/DummyDriver pattern as
* space.repo.spec.ts, plus the production `CamelCasePlugin` (so the compiled SQL
* carries the real snake_case column names, e.g. `last_updated_source`) and a
* thin driver that returns ONE fixed row for every query. The fixed row is what
* lets the repo's guard reads (root snapshot / recursive descendants / restore
* target) resolve non-empty so execution reaches the subtree UPDATE we assert on
* a bare DummyDriver returns no rows and both methods short-circuit before the
* update. We never hit a real database; we capture each compiled statement via
* Kysely's `log` hook and inspect the `update "pages" set ...` SQL.

/**
* SQL-builder unit test for the jsonb-merge invariant of
* SpaceRepo.updateGitSyncSettings (review comment #694 / test-strategy item #6).
*
* The merge is RAW SQL, so a behavioural test would need a live Postgres which
* is intentionally out of scope here (the reviewer's own §13.3 was deferred for
* the same reason). Instead we follow the existing repo-spec convention
* (ai-agent-roles.repo.spec.ts) of NOT executing: we compile the query with a
* DummyDriver Postgres dialect and assert the generated SQL preserves sibling
* keys. The structural invariant the SQL must encode:
*
* settings := COALESCE(settings, '{}') || jsonb_build_object('gitSync', ...)
* gitSync := COALESCE(settings->'gitSync', '{}') || jsonb_build_object(key, value)
*
* The OUTER `||` merges into the existing top-level `settings`, so a sibling
* top-level key (e.g. `sharing`) is preserved. The INNER COALESCE merges into
* the existing `gitSync` object, so a sibling key inside gitSync (e.g. `other`)
* is preserved. A naive `set settings = jsonb_build_object('gitSync', ...)`
* would clobber both this test guards exactly that regression.
