Resolve the code-review findings from comment #1571 on PR #119.
Engine (packages/git-sync):
- Idempotent CREATE on retry: before createPage, look the page up in the
live Docmost tree by (parentPageId, title) and ADOPT it instead of
duplicating when a prior cycle created it but failed to persist the
pageId back to disk. Only trust a COMPLETE tree for the lookup; fall
back to createPage otherwise. Covered by new tests incl. a complete=false
regression-lock.
- Route applyPullActions diagnostics through an injected logger instead of
bare console (thread log from the cycle).
- Add a timeout to the git execFile chokepoint (runRaw) so a hung git
subprocess cannot wedge a sync cycle.
- Translate remaining Russian code comments to English.
- Remove dead standalone-CLI code (parseArgs/PushParsedArgs,
parseSettings/envSchema, loadSettingsOrExit + config-errors.ts) and the
matching index exports/specs; keep the Settings type.
- Fix the dangling docs link in package.json.
- Add a schema-surface snapshot guard so any drift in the vendored
document schema is a loud, must-review CI failure (+ provenance header).
Server (apps/server):
- Add a configurable watchdog timeout to the spawned git http-backend so a
stalled push cannot hold the per-space lock forever
(GIT_SYNC_BACKEND_TIMEOUT_MS).
- Close the in-process TOCTOU window in SpaceLockService.withSpaceLock by
reserving the slot synchronously before acquire.
- Add tests: removePage git-sync provenance (both branches), ensureServable
force-push-protection git configs, and the phase-B+ datasource methods.
Docs / build:
- AGENTS.md: list git-sync as the fifth workspace package and note the
three schema mirrors; fix the dangling git-sync-plan.md backlog link.
- pnpm-lock.yaml: add the missing @docmost/git-sync workspace link so
pnpm install --frozen-lockfile (CI default) succeeds.

Closes the architecture item from the #119 review: drop the "vendored from
docmost-sync" framing and the CJS↔ESM `Function('import()')` bridge so the engine
is a normal first-class gitmost package.
Part 1 — vendoring markers removed (prose only, zero behavior change): reworded
"VENDORED into gitmost" / "vendored from docmost-sync" / "Engine LOGIC is
byte-identical" / "it's a port" comments across the engine. Behavior-bearing
strings are untouched: BOT_AUTHOR_NAME/EMAIL and the `Docmost-Sync-Source:`
provenance trailers (changing them would break git authorship + the loop-guard).
Part 2 — the package is now ESM (matching the sibling @docmost/mcp): `type: module`,
tsconfig Node16, `.js` extensions on relative imports, and a static
`import { marked }` replacing the `new Function('return import(...)')` /
`loadMarked` hack — the bridge is GONE from the package. The CommonJS NestJS
server loads the now-ESM engine via a new `git-sync.loader.ts` that mirrors the
existing `docmost-client.loader.ts` mcp loader exactly (Function-indirected
dynamic import + cached promise + retry-on-reject). The 4 server consumers
(orchestrator/datasource/vault-registry/git-http-backend) call `await loadGitSync()`
for value exports; types stay `import type` (erased). The converter-gate spec —
which needs the real converter — loads the package's TS source via a jest
moduleNameMapper + isolatedModules (documented in that spec); the other git-sync
specs mock the loader.
Verified: engine builds pure ESM (no Function/require leftover), vitest 614,
editor-ext build, server + client tsc, full server jest 1397/0. Live stand
smoke-test: server starts clean on the ESM engine (no ERR_REQUIRE_ESM), a real
sync cycle runs through the loader, and the basic e2e suite is 12/12 (clone via
git-http-backend, push, pull, delete, 3-way merge — all through the new loader).

Addresses the stability + test-coverage warnings from the #119 review:
- git-http-backend.service.ts: add `'error'` handlers to child.stdout/stderr. An
EventEmitter 'error' with no listener (e.g. EPIPE when the client aborts
mid-response) is rethrown by Node as an uncaught exception and crashes the
process; now swallowed + logged (never echoed to the client).
- TEST INFRA: a jest setupFile shims `navigator`/`MessageChannel` for the `node`
testEnvironment. react-dom@18 reads `navigator` at module-init (pulled in via
@docmost/editor-ext -> @tiptap/react), so every spec transitively importing the
conversion engine — including git-http.service.spec.ts — previously FAILED TO
LOAD ("navigator is not defined") and ran ZERO tests. With the shim those specs
now run (git-sync integration: 11 suites / 133 tests green).
- git-http.service.spec.ts: cover the 503 lock-held push path — `ingestExternalPush`
rejecting `GitSyncLockHeldError` -> 503 + Retry-After + "git-sync busy, retry",
no double header write (+ the already-headers-sent no-rewrite path).
- git-http-backend.service.spec.ts: unit-test run() — child 'error'/'close' before
headers -> 500; normal CGI parse+stream; stdout/stderr 'error' (EPIPE) swallowed;
synchronous spawn throw -> 500.
- page-change.listener.ts: implement OnModuleDestroy to clearTimeout all pending
debounce timers on shutdown (+ test).
- .env.example: vaults are non-bare working repos, not "bare repos".

The reconcile choreography (ensureRepo -> merge-check -> ensureBranch ->
checkout('docmost') -> pull -> push) was hand-rolled in the app orchestrator's
driveCycle, duplicating an order the vendored engine owns and could drift from on
upgrade — the failure mode is data clobber. Lift it into @docmost/git-sync as a
single entry point, `runCycle(deps)`. The orchestrator now calls runCycle and
keeps only the lock (its caller) and the gitmost-specific delete-cap POLICY,
injected as the `resolveApplyClient` hook (the engine does the dry-run, hands the
hook the planned delete count — Infinity if planning failed — and uses whatever
client it returns for the apply). driveCycle drops from ~150 lines to ~30.
Tests:
- engine test/cycle.test.ts: composition (merge-in-progress short-circuit;
ensureRepo->ensureBranch->checkout staging order before the pull; the cap hook
is consulted with the planned count; no dry-run when no hook).
- engine test/cycle-roundtrip.test.ts: runCycle against a REAL VaultGit in a temp
repo with a faked Docmost client — a git-originated CREATE flows pull->push and
the assigned pageId is written back; an unresolved merge short-circuits before
any client call.
- orchestrator spec rewired to mock runCycle and assert the wiring + the
resolveApplyClient cap policy (the engine-internal cycle-order/merge tests moved
to the engine).
Validated end to end on a live stand (real Postgres/Redis + server): a git clone
-> edit -> push over the /git remote round-trips the change into the Docmost page
through the refactored cycle.

The /git smart-HTTP host 404'd EVERY fetch and push: PATH_INFO was built as
`/<spaceId>.git/<subpath>`, so `git http-backend` resolved the repo at
`<GIT_PROJECT_ROOT>/<spaceId>.git` — which does not exist. The vault is a NON-bare
working repo (the engine needs a working tree) at `<dataDir>/<spaceId>`, so the
CGI repo path must be `<spaceId>` (git http-backend serves the `.git` inside).
The URL's conventional `.git` suffix is already stripped to `spaceId` by
parseGitPath; re-appending it for PATH_INFO was the bug.
Found by standing up a full e2e stand (real Postgres/Redis + server + a real git
clone/push over the /git remote): clone and push both 404'd until this fix, after
which a clone → edit → push round-trips the change all the way into the Docmost
page.
Also extracts the CGI-env construction into a pure, exported `buildGitBackendCgiEnv`
and adds unit tests (the env build was previously untested — the gap this bug hid
in): a regression guard pinning PATH_INFO to `/<spaceId>/<subpath>` (no `.git`),
plus method/query/content-type/remote-user forwarding and the conditional
GIT_PROTOCOL.

Closes the test-coverage warning that the smart-HTTP push ingest path was
unexercised. Adds 5 cases: receive-pack streams BEFORE the Docmost cycle; a
held lock throws GitSyncLockHeldError and runs neither the receive-pack nor the
cycle; a post-push cycle error is swallowed (the push is durable, poll retries)
while the lock is still released; a missing service user runs the receive-pack
but skips the immediate cycle; and a globally-disabled git-sync refuses without
touching the lock.
(The 503/Retry-After mapping in git-http.service is the sibling warning; its spec
is in the repo's pre-existing set of jest suites that can't load locally via the
react-dom/tiptap transform chain, so that case is left for CI.)

The per-space single-writer lock — Redis CAS leader lock (SET NX PX, DEL-CAS and
PEXPIRE-CAS Lua), the in-process mutex, the per-process instanceId and the
heartbeat — lived inline in GitSyncOrchestrator. Extract it into a dedicated
@Injectable() SpaceLockService exposing one narrow surface, withSpaceLock(spaceId,
fn), so the lock is the orchestrator's only Redis-lock touch-point and is testable
in isolation. The orchestrator now injects SpaceLockService and both consumers
(runOnce, ingestExternalPush) go through spaceLock.withSpaceLock — behavior
unchanged (same sentinel returns, same 503-on-lock-held contract). Orchestrator
drops 591→472 lines.
Adds space-lock.service.spec.ts asserting the lock SEMANTICS against a fake Redis
(the test-coverage warning from the review): the SET NX/PX args, the DEL-CAS and
PEXPIRE-CAS Lua + ARGV[1]=instanceId, plus the lock-held / in-progress / throw-
still-releases paths. The orchestrator spec is unchanged in count and stays green
(it now builds the real SpaceLockService over its mock Redis).

The implementation spec docs/git-sync-plan.md was removed as completed, but ~44
code comments still cited it as "plan §N". Strip those citations (comments only),
keeping each comment grammatical. The vendored engine's own "SPEC §N" references
point at a different, still-present spec and are left untouched.

The debounce map value carried `workspaceId`, but the scheduled cycle closes over
the `workspaceId` argument directly — the field was written and never read.
Replace the entry struct with `Map<string, NodeJS.Timeout>` (the timer handle is
all the map tracks). No behavior change. (page-change.listener.spec is in the
repo's pre-existing set of jest suites that can't load locally via the
react-dom/tiptap transform chain — unaffected by this change; tsc clean.)

The two-way block diff (yjs-body-merge.diffBlocks) and the three-way merge
planner (three-way-merge.lcsPairs) built the identical backward-filled LCS DP
table inline. Extract it to lcs.ts (buildLcsTable); each caller keeps its own
traceback. No behavior change — merge specs unchanged and green.

Two stability warnings from the #119 review:
1. delete-cap no longer drops deletions forever. When planned deletes exceed
GIT_SYNC_MAX_DELETES_PER_CYCLE the apply client's deletePage now THROWS
instead of resolving to a no-op. A throw is recorded by the engine as a
per-page failure, so `refs/docmost/last-pushed` is NOT advanced past the
commit that dropped the files — the next cycle re-diffs from the un-advanced
ref and re-plans the same deletes (a transient over-cap is retried, not
silently dropped and then recreated by the next pull). Previously a resolving
no-op let the engine count `deleted++` with no failure, advance the ref, and
never replay the deletions.
2. git-sync soft-delete and restore now stamp provenance. deletePage routes
GIT_SYNC_PROVENANCE through pageService.removePage, and restorePage stamps
lastUpdatedSource='git-sync' on the restore update — so the page-change
listener's loop-guard (skip when lastUpdatedSource==='git-sync') recognizes
both as its own writes instead of scheduling a wasted echo cycle. Done via a
backward-compatible optional `lastUpdatedSource` param on
pageRepo.removePage/restorePage (omitted for ordinary user deletes/restores).

Addresses the documentation/convention warnings from the #119 review:
- .env.example: add the GIT-SYNC block (9 GIT_SYNC_* vars with defaults), noting
GIT_SYNC_SERVICE_USER_ID is required when sync is enabled.
- yjs-body-merge.ts: translate the Russian review note in the docstring to
English (comments-only-in-English rule).
- persistence.extension.ts: correct the stale "git-sync writes are full-body
replaces" rationale — a git-sync write is now a block-level merge into the live
doc, which is why it is debounced like a human edit rather than snapshotted.
- history-item.tsx: the GitSyncBadge version is created on the PUSH path (writing
the git body back into the doc), not by the pull — fix the comment.
- edit-space-form.tsx: log the raw error in the git-sync toggle catch instead of
swallowing it (AGENTS.md).

Upgrades the 2-way body merge to a real diff3 three-way merge (review #5), so a
block ONLY the human changed is KEPT when git changed a DIFFERENT block — the
2-way merge would revert it to git's stale version.
Engine: the push update loop reads the last-synced pre-image
(`git.showFileAtRef(refs/docmost/last-pushed, path)`) and passes it as the
optional `baseMarkdown` to `client.importPageMarkdown` (the common ancestor).
Server: gitmost-datasource converts base+incoming, and writeBody runs a block-
level diff3 (new three-way-merge.ts `diff3Plan`): live-only change -> keep live,
git-only change -> take git, both-changed -> git wins (conflict policy), inserts/
deletes from either side preserved. Without a base (createPage) it falls back to
the 2-way merge. Crash-safety unchanged (docs built before the connection opens).
Tests: three-way-merge.spec.ts (14 — every diff3 case incl. the cross-block
preservation and conflict policy), yjs-body-merge 3-way (real Y.Docs: human's
block instance preserved while git's block is applied), plus an engine test that
the base is forwarded from showFileAtRef. Existing push assertions updated for the
new base arg. git-sync 589 pass; server merge/datasource/gate 62 pass; typecheck
clean.

Supersedes the active-session "defer" guard with a real merge (review #5 —
"запись делать через мерж", not skip-while-editing).
writeBody no longer does delete-all + re-insert (which discarded a concurrent
editor's in-flight changes on every sync). It now diffs the live body against the
incoming git body at TOP-LEVEL BLOCK granularity (LCS over a canonical structural
serialization) and applies only the minimal inserts/deletes:
- a block a human is editing is left UNTOUCHED when git changed a DIFFERENT block;
- an unchanged resync is a complete 0-op write;
- Yjs CRDT-merges the minimal ops with concurrent edits.
New yjs-body-merge.ts (mergeXmlFragments + cloneXmlNode + diffBlocks) is pure-Yjs
and unit-tested with real Y.Docs (8 tests): identical->0 ops, edit-one-block keeps
the other block instances, append/delete keep neighbours, marks survive the
cross-doc clone. Crash-safety kept: the incoming doc is built before the
connection opens, so a transform failure can't empty the body.
Removed: the ActiveEditSessionError defer path and the now-unused
CollaborationGateway.getActiveEditorCount.
Honest limitation: this is a 2-way merge — for a block BOTH sides changed since the
last sync, git wins (no common ancestor to decide). A full 3-way merge would need
the last-synced base plumbed from the engine; the dominant cases (unchanged
resync, edits to different blocks) are now lossless.

Review finding #5: the git -> page body write (writeBody) did a full-body replace
(delete-all + re-insert) on the shared Yjs doc. Applied while a human is editing
the page, it discarded their in-flight changes; and TiptapTransformer.toYdoc ran
AFTER the fragment was cleared, so a conversion failure could leave the page with
an empty body.
Fixes:
- Active-session guard: CollaborationGateway.getActiveEditorCount(documentName)
reports live human (websocket) editor sessions for a doc, excluding server-side
direct connections. writeBody now throws ActiveEditSessionError when an editor
is connected. The engine's push loop already isolates each importPageMarkdown in
try/catch and does not advance the loop-guard on failure, so the write is simply
retried on the next poll once the editor disconnects — never a clobber.
- Crash-safe conversion: build the replacement Yjs update BEFORE opening the
connection / clearing the fragment, so a transform failure can never leave the
body empty.
Also updates the server-side converter gate spec to the corrected round-trip
shape: the block-image hoist no longer leaves a leading empty paragraph (the
git-sync converter fix in 7d39c16b, now reaching the built package).
A true merge of git content into a live Yjs session is out of scope (it needs a
real 3-way text merge with no shared update lineage); deferring the write while a
page is being edited is the safe, owner-approved minimum.

Expose each git-sync-enabled space as a clonable/pushable git repo over HTTP,
so `git clone https://<user>:<pass>@<host>/git/<spaceId>.git` works and external
pushes flow back into Docmost pages — gitmost itself acts as the git host (no
external GitHub/Gitea, no SSH).
Transport: shell out to `git http-backend` (CGI; git is already in the runtime
image) which implements the full smart-HTTP protocol (info/refs, upload-pack,
receive-pack, protocol v2). A raw Fastify route `/git/*` (mounted at the root,
outside the `/api` prefix) bridges the request/response to the CGI; passthrough
content-type parsers for the git media types stream the raw body to stdin.
Reuse the existing engine: clients push the vault's `main` branch, whose commits
beyond `refs/docmost/last-pushed` the engine already reconciles into Docmost.
- http/git-http.service.ts — auth (HTTP Basic -> AuthService.verifyUserCredentials),
self-resolved workspace (DomainMiddleware does not run for this raw route),
per-space gating (global + per-space gitSync flags, 404 hides existence),
CASL authz (Read=fetch, Manage=push), dispatch.
- http/git-http-backend.service.ts — spawn `git http-backend`, binary-safe CGI
response parsing (Status/headers/body), stream to the socket.
- http/git-http.helpers.ts — pure path parse, service->kind mapping, gate decision
(unit-tested); rejects literal and percent-encoded path traversal.
- orchestrator: extract reusable withSpaceLock (CAS-guarded lock heartbeat so a
long push cannot let the lock expire mid-cycle) and add ingestExternalPush
(receive-pack + Docmost cycle under one lock; 503 on contention).
- vault-registry: ensureServable() — ensureRepo + idempotent receive.denyCurrentBranch
=updateInstead / denyNonFastForwards / http.receivepack / http.uploadpack.
- env: GIT_SYNC_HTTP_ENABLED (defaults to GIT_SYNC_ENABLED) + validation.
- main.ts: register the /git/* route and the git content-type parsers.
Tests: pure helpers, CGI parsing, and the GitHttpService handler (auth/gate/authz
+ workspace resolution). Server tsc + git-sync/env suites green.

Comprehensive-review follow-ups (APPROVE WITH SUGGESTIONS; no critical issues):
- poll interval is now actually configurable: replaced the hardcoded
@Interval('git-sync-poll', 15000) with a dynamic SchedulerRegistry interval
registered in onModuleInit from getGitSyncPollIntervalMs() (cleared in
onModuleDestroy); /status and the real cadence now share one config source.
Boots logging 'poll interval registered (Nms)'.
- loop-guard now ALWAYS applies: the lastUpdatedSource==='git-sync' skip was
nested inside the !spaceId/!workspaceId branch, so structural self-writes
(CREATE/MOVE/RESTORE/SOFT_DELETE, which carry spaceId+workspaceId) bypassed it
and re-triggered cycles. Fetch the page row once, guard unconditionally, then
resolve space/workspace.
- remove the dead PAGE_CONTENT_UPDATED subscription (it's a BullMQ job, never an
EventEmitter event; body edits arrive via PAGE_UPDATED).
- fix the stale datasource comment (PageService DOES stamp 'git-sync' now).
- env getters: parseInt radix 10 + NaN/<=0 fallback for poll/debounce (+ max
deletes), with 6 new environment.service.spec tests.
tsc clean; jest 723 pass; live cycle re-verified post-refactor (ran, push
applied, unflagged 92-page space untouched).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Fixes found by the live pull/push e2e:
- CRITICAL: driveCycle never checked out the 'docmost' branch before
applyPullActions, so Docmost content was written straight onto 'main',
clobbering local file edits before push could diff them. Now checkout
'docmost' before pull (applyPullActions commits there then checks out main +
merges) — mirrors the engine's pull main(). Round-trip now works both ways.
- add an unresolved-merge guard (SPEC §9): skip the cycle if the vault is
mid-merge instead of failing on checkout.
- SAFETY: enabledSpaces() is now STRICT opt-in — only spaces with
settings.gitSync.enabled===true; removed the all-spaces fallback that synced
every space (incl. a 92-page one) the moment GIT_SYNC_ENABLED flipped.
- SAFETY: per-cycle delete cap (GIT_SYNC_MAX_DELETES_PER_CYCLE, default 5):
dry-run the push, and if planned deletes exceed the cap, run the apply with
deletePage neutralized — phantom absence-deletions from a non-convergent vault
can't soft-delete real pages. Fails safe if the dry-run throws.
- fix manual trigger: TriggerGitSyncDto.spaceId needs @IsUUID or the global
whitelist ValidationPipe strips it (arrived undefined -> vault 'undefined').
Live-verified on an isolated flagged space: push (vault file edit -> Docmost
content, stamped lastUpdatedSource='git-sync') and pull (Docmost rename -> vault
file + meta) both work; an unrelated 92-page space stayed untouched throughout.

Native data plane for git-sync (plan §3, §8.1):
- provenance: widen actor to 'user'|'agent'|'git-sync' (jwt-payload,
auth-provenance decorator); PersistenceExtension resolves lastUpdatedSource
with precedence agent > git-sync > user, debounced history (like a human edit,
not the agent's immediate snapshot).
- GitmostDataSourceService implements @docmost/git-sync's GitSyncClient natively:
reads via PageRepo/SpaceRepo (listSpaceTree complete:true, getPageJson), writes
via PageService (create/removePage soft-delete/movePage with computed fractional
position/update-rename/restore) + the writeBody linchpin through collab
openDirectConnection('page.'+id, {actor:'git-sync'}) mirroring
collaboration.handler withYdocConnection 'replace'. bind({workspaceId,userId})
returns the context-bound client for the orchestrator.
- 10 unit/contract tests (mapping + soft-delete + move-position), tsc clean.
Known gap (closed in A.4b): PageService.create/update/movePage only branch on
actor==='agent'; git-sync provenance is already passed through so the row source
marker propagates once PageService honors 'git-sync'. Module/orchestrator/config
come next.

Code-review follow-ups (Approve-with-comments) for batch #197
(context badge #189 / e2e in CI #187 / inline MCP test #170):
- server: extract the duplicated chatContextWindow ::text->positive-int
coercion (resolve() + getMasked()) into an exported parsePositiveInt
helper and unit-test its branches (200000/1.9/0/-5/""/abc/undefined),
closing the untested read-path gap.
- client: merge the two backward scans over messageRows into one pure,
exported selectContextBadge helper (numerator and denominator still
taken from the most recent row carrying EACH value) and unit-test the
different-rows and fresh-zero-doesn't-shadow cases.
- client: extract the MCP "Test" button tristate presentation into a pure
mcpTestButtonView helper (collapses the two parallel if/else chains) and
unit-test idle/ok-with-tools/ok-no-tools/failed label+tooltip branches.
- ci: redirect the backgrounded prod server's stdout/stderr to a log file
in e2e-mcp and cat it on failure, so a start-up crash is diagnosable
instead of surfacing only as the generic health timeout.

The floating chat window's header badge flipped meaning — a live per-turn token
counter while streaming, the persisted context size at rest — so it "reset to 1"
on each prompt and conflated two different numbers. Replace it with a stable
"current / max" context badge (e.g. `572 / 200k`). The live "Thinking · N tokens"
inside the chat body stays; only the duplicate live counter is removed from the
header.
Max comes from a new admin setting "Context window (tokens)". The server resolves
it and attaches `maxContextTokens` to the completed assistant turn's metadata
(next to contextTokens), so the badge needs no client-side model resolution and
this survives public shares / per-role models.
Server:
- ai.types: chatContextWindow on AiProviderSettings + PROVIDER_SETTINGS_KEYS +
ResolvedAiConfig + MaskedAiSettings.
- workspace.repo: chatContextWindow in AI_PROVIDER_SETTINGS_ALLOWED (parity).
- update-ai-settings.dto: @IsInt @Min(0) chatContextWindow.
- ai-settings.service: coerce the ::text-stored value to a positive int in
resolve()/getMasked().
- ai-chat.service: flushAssistant writes metadata.maxContextTokens (>0); the
completed turn passes resolved.chatContextWindow.
Client:
- ai-chat.types: maxContextTokens on the message-row metadata.
- ai-chat-window: read maxContextTokens; render "current [/ max]"; drop the
liveTurnTokens state/branch and the onLiveTurnTokens prop; new tooltip.
- chat-thread: remove the live-turn-token throttle effect and plumbing.
- count-stream-tokens: drop the now-dead liveTurnTokens()/types; keep
estimateTokens.
- settings: chatContextWindow on IAiSettings(+Update) + a NumberInput in the AI
provider settings form.
i18n: add the badge/settings keys (en, ru); remove the two now-unused keys.
Tests: flushAssistant maxContextTokens, DTO validation, trim token tests.

External MCP tools (web search, crawl) had no per-call timeout: a hung
tool call was only broken by the 15-min transport silence timeout shared
with the chat provider, and a server that kept the socket warm but never
returned could spin until the user cancelled.
Add two independent, composing bounds for external MCP traffic (the chat
provider path is unchanged):
- Silence 5 min: buildPinnedDispatcher now overrides headersTimeout/
bodyTimeout with mcpStreamTimeoutMs() (AI_MCP_STREAM_TIMEOUT_MS,
default 300000) on the external-MCP dispatcher only, so a byte-silent
upstream is severed in ~5 min instead of 15.
- Total per-call 15 min: wrapToolWithCallTimeout wraps each external
tool's execute with a fresh AbortController + timer composed with the
turn signal via AbortSignal.any (AI_MCP_CALL_TIMEOUT_MS, default
900000). It RACES the call against the abort signal because
@ai-sdk/mcp does not settle its in-flight promise on abort, so a
warm-but-stuck call would otherwise hang forever.
On timeout the call surfaces as a tool-error and the agent loop recovers.
Add tests (incl. a never-settling real-client-style stub) and document
both env vars in .env.example.
- Invert the transport layers so the pre-response retry is OUTERMOST and the
provider-HTTP instrumentation is INNER. Before, the retry lived inside
createStreamingFetch (under the instrumentation), so a reset the retry
recovered from logged only a clean "OK status=200" — the
"PRE-RESPONSE FAILED ... ECONNRESET ... idleSincePrevCall" signal went blind
exactly when the fix works, and AI_STREAM_KEEPALIVE_MS couldn't be tuned from
prod data. Now createStreamingFetch is the dispatcher-bound BASE (no retry) and
a new withPreResponseRetry() wraps it; ai.service composes
withPreResponseRetry(createInstrumentedFetch('AiService:provider-http',
createStreamingFetch())), so every attempt — including recovered resets — flows
through the instrumentation. (Also expresses the keepAlive-config vs retry-
behavior boundary structurally, per review #3.)
- Add the retry-exhaustion test: a server that resets EVERY connection, asserting
the call rejects with a retryable connection error AND exactly
PRE_RESPONSE_CONNECT_RETRIES + 1 (= 3) requests reached the server — pinning the
bound and that the final error propagates (guards an off-by-one / infinite loop
/ swallowed error). Existing happy-retry + abort tests moved onto

The real cause of the long-task "Lost connection to the AI provider" — the
earlier 300s-timeout fix (#176) was the wrong layer. The provider-HTTP telemetry
on the user's deploy shows the failures are PRE-RESPONSE `read ECONNRESET` ~500ms
in (not a 300s/15min timeout), correlated with idleSincePrevCall ~42s and large
bodies; and crucially a retry of the SAME request often succeeds. A direct probe
to the real z.ai endpoint does NOT reset (113KB bodies and a 45s-idle keep-alive
reuse both succeed), and another agent (opencode) runs fine from the same infra —
so the provider is healthy and the egress network is usable. The difference is
the transport: undici's keep-alive pool REUSES a socket that the deployment's
egress (NAT / firewall / conntrack) silently dropped during a long idle gap, so
the next request resets pre-response.
Fix (brings gitmost in line with clients that don't reuse stale sockets):
- Keep-alive recycling: the streaming dispatcher (chat fetch AND the external-MCP
dispatcher, via the shared streamingDispatcherOptions) now sets
keepAliveTimeout + keepAliveMaxTimeout to a 10s recycle window
(AI_STREAM_KEEPALIVE_MS), so a connection idle longer than that is closed
instead of reused — a long-gap step opens a fresh connection. keepAliveMaxTimeout
also caps a server-advertised keep-alive so the provider can't widen the window.
- Pre-response connection retry: createStreamingFetch retries a connection-level
reset (ECONNRESET / UND_ERR_SOCKET / ECONNREFUSED / EPIPE / *_TIMEOUT) on a
fresh connection up to 2 times. This is SAFE because fetch() only rejects before
the Response resolves — a started stream is never replayed; an abort (client
disconnect) is never retried.
Tests: ai-streaming-fetch.spec — keep-alive options, streamKeepAliveMs env,
isRetryableConnectError, and a server that resets the first connection so the
retry must land on a fresh one (+ aborted requests are not retried). Verified on
the stand that a normal turn still streams (reasoning + text + finish) through the
new transport. server tsc + ai/mcp specs green.
Note: root cause is the deployment's egress dropping idle connections (Traefik is
inbound-only); this makes the app resilient to it. AI_STREAM_KEEPALIVE_MS can be
lowered if the egress drops faster than ~10s.

Addresses the second #177 review:
- Architecture (the silent allowlist drift): the writable provider-setting keys
were maintained by hand in two TS-uncheckable places — the key-loop in
ai-settings.service and the SQL ALLOWED list in the generic workspace repo (a
miss there silently dropped a field on persist, exactly what bit chatApiStyle).
Introduce one typed source of truth PROVIDER_SETTINGS_KEYS in ai.types
(`satisfies readonly (keyof AiProviderSettings)[]`), have the service consume
it, and keep the repo's own copy (it can't import AI types) guarded by a parity
test so any future drift fails in CI.
- Tests:
- ai.service.include-usage.spec: mocks @ai-sdk/openai-compatible and asserts the
factory is called with { includeUsage: true, baseURL, apiKey, fetch, name } —
`.provider` alone could not catch a dropped includeUsage (the token-usage
zeroing regression); also asserts the 'openai' style does NOT use it.
- ai-provider-settings-keys.spec: the allowlist parity check + DTO validation
for chatApiStyle (@IsIn accepts both values, rejects garbage, optional).
- CHANGELOG: [Unreleased] entries for the new "Protocol" / chatApiStyle setting
and the default provider change (openai -> openai-compatible). (#175, #177)
server + client tsc clean; 42 ai/settings specs green.

Rebuilt on develop (after #176) and reworked per review: instead of inferring the
provider from baseUrl (`if (baseUrl)`), the admin picks the chat provider
EXPLICITLY via a new `chatApiStyle` ('openai-compatible' | 'openai'), mirroring
the existing sttApiStyle. A custom baseURL can front real OpenAI too, so the
heuristic was fragile.
Why reasoning was missing: glm-5.2 (and DeepSeek etc.) stream their thinking as
`reasoning_content`, but the official @ai-sdk/openai provider does not map that
field. 'openai-compatible' uses @ai-sdk/openai-compatible, which does — so
reasoning parts now stream (verified live: reasoning-start/delta/end appear, and
disappear when set to 'openai').
- Default (unset) = 'openai-compatible', so existing openai+baseUrl workspaces
surface reasoning with no admin action. No DB migration (field lives in the
settings.ai.provider JSON blob).
- includeUsage: true on the openai-compatible model — without it the provider
omits streamed usage, zeroing the live token counter / reasoning-token
metadata. The official provider always sent it; this keeps parity. (Confirmed
live: usage.totalTokens present.)
- openai-compatible has no default endpoint, so with no baseURL (real OpenAI, or
a role's cross-driver override that cleared it) it falls back to the official
provider.
Plumbing: ai.types (ChatApiStyle / CHAT_API_STYLES + AiProviderSettings /
MaskedAiSettings), update DTO (@IsIn), ai-settings.service (resolve / getMasked /
update allowlist), workspace.repo updateAiProviderSettings ALLOWED (the second,
SQL-level allowlist the review missed — without it the field never persisted),
ai.service selector. Client: ai-settings-service types + a Protocol <Select> in
the chat section + i18n (en/ru). Scope is chat-only (embeddings don't stream
reasoning; STT already has sttApiStyle).
Tests: ai.service.spec — 4 cases (openai-compatible+baseURL, openai+baseURL,
default-unset, openai-compatible-without-baseURL fallback). Verified on the stand:
default streams reasoning + usage; 'openai' drops reasoning; the setting
round-trips. server + client tsc clean; 36 ai/settings specs green.

- Wording: every comment now says the stream timeouts are RAISED to a
generous-but-finite ~15-min silence timeout, not "disabled (0)" (the stale
comments contradicted the code, which uses AI_STREAM_TIMEOUT_MS, default
900000ms).
- Architecture (the load-bearing-temporary trap): the streaming fetch reached
the chat provider only by riding the "temporary DIAGNOSTIC" telemetry, so
deleting the telemetry by its own label would silently revert the timeout fix.
Legitimize it: rename ai-http-diagnostics.ts -> ai-provider-http.ts,
createDiagnosticFetch -> createInstrumentedFetch, field aiDiagnosticFetch ->
aiProviderFetch, drop the "temporary" labels, and document the chat transport
(streaming fetch + instrumentation) as one intentional construct.
- Docs: AI_STREAM_TIMEOUT_MS added to .env.example next to AI_EMBEDDING_TIMEOUT_MS.
- Tests:
- ai-provider-http.spec: createInstrumentedFetch delegates to the injected
baseFetch with the same input/init, returns the Response untouched, rethrows
the error, and defaults to global fetch — covering the baseFetch seam.
- ai-streaming-fetch.spec: the delayed-server test is now LOAD-BEARING — with
AI_STREAM_TIMEOUT_MS set below the 1.5s server delay the call actually rejects
(a lost dispatcher -> global 300s default would NOT), proving the configured
dispatcher is wired; plus the default-timeout happy path.
server tsc clean; ai-streaming-fetch / ai-provider-http / ai.service / mcp-servers
/ ai-error specs green (41).

Long research turns failed mid-task with "Lost connection to the AI provider".
Node's global fetch (undici) defaults BOTH headersTimeout and bodyTimeout to
300_000ms, and the chat provider + the external-MCP dispatcher both ran on it
with no override, so:
- the z.ai chat stream dropped when a late step's huge accumulated context
pushed the model's time-to-first-token past 5 min (the model reasons
server-side with NO streamed reasoning, so the connection is silent until the
first answer token — reproduced: even a trivial glm-5.2 query has a ~4-8s
first-chunk gap; a long run reaches 400k+-token steps), or a reasoning model
paused >5 min between chunks (bodyTimeout);
- the crawl4ai SSE transport, held open across the whole turn, dropped when it
idled >5 min between tool calls.
Fix: a dedicated undici dispatcher whose stream timeouts are raised to a
generous-but-FINITE silence timeout (default 15 min, AI_STREAM_TIMEOUT_MS) on
each path. NOT disabled (0): that would let a genuinely hung provider — with the
client still connected — hang forever, since the turn's abortSignal only fires on
client disconnect. The timeout bounds SILENCE (time-to-first-byte and the gap
BETWEEN chunks), NOT total turn duration, so an arbitrarily long turn that keeps
streaming is never cut; only a stream quiet for >15 min is treated as a hang.
- ai-streaming-fetch.ts: createStreamingFetch() + streamTimeoutMs() /
streamingDispatcherOptions() (the shared, configurable timeout).
- ai.service: the chat provider fetch is createStreamingFetch(), wrapped by the
existing passive ECONNRESET telemetry (createDiagnosticFetch gained an
optional baseFetch) so the telemetry observes the SAME transport.
- mcp-clients: the SSRF-pinned Agent uses streamingDispatcherOptions().
Investigation: reproduced the transport mechanism against the real z.ai endpoint
(a 1ms headersTimeout throws UND_ERR_HEADERS_TIMEOUT — the exact drop) and ran
the actual research agent to a ~428k-token context. Verified the fixed path
streams cleanly live (glm-5.2 turns finish; telemetry confirms the streaming
fetch is in use).
Tests: ai-streaming-fetch.spec (default 15m + env override + invalid fallback +
both-timeouts + streams a delayed response); ai-http-diagnostics + ai/mcp specs
green. server tsc clean.

Investigate the intermittent (~20-30%) long-turn failure
"Lost connection to the AI provider" = AI_RetryError / read ECONNRESET
on the gitmost->z.ai link (browser-agnostic, mid-turn). Pure
instrumentation, no behavior change:
- ai-http-diagnostics.ts: a passive fetch wrapper injected into the
OpenAI-compatible (z.ai) client. Per provider HTTP call it logs
time-to-headers/status on success, and on a pre-response rejection the
latency, error code/cause, request-body size and idle-gap since the
previous call. The Response is returned untouched (streaming intact),
errors rethrown unchanged; no retry/timeout/dispatcher.
- ai.service.ts: wire the instrumented fetch into the openai case only.
Lets us classify the reset as connection-phase vs mid-stream before
choosing a fix, without repeating the reverted RetryAgent (#140).
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The custom undici RetryAgent + aiFetch transport added for issue #140
did not actually heal mid-stream provider drops: undici's retry path is
a Range-based download-resume that SSE/chat-completions endpoints cannot
satisfy, so a reset after the first byte only swapped ECONNRESET for a
"server does not support the range header" error. Its only real effect
was reconnecting a poisoned keep-alive socket before the first byte, and
PR #141 on top of it turned the 60s headers timeout into deterministic
~61s failures (plus CONTENT_LENGTH_MISMATCH from retrying a POST body
after a timeout abort). The root cause is the z.ai coding endpoint, not
our transport.
Remove the whole layer and return all AI provider calls to Node's
default global fetch.
- delete integrations/ai/ai-http.ts and its spec
- ai.service.ts: drop the aiFetch import, the AI_BYPASS_RESILIENT_FETCH
diagnostic toggle, and fetch:aiFetch from every chat/embedding/STT
factory; raw STT call back to global fetch
- ai-chat.controller.ts: drop the stream-timing START log + startedAt
- ai-chat.service.ts: drop the first-chunk/FINISHED/ERROR timing logs
- .env.example: drop AI_BYPASS_RESILIENT_FETCH

Extend ai-http.spec with two loopback-server tests: a provider that stalls
without sending headers triggers the (lowered) headersTimeout and is retried on a
fresh connection, recovering; a healthy fast response passes through in one
attempt. No external network calls.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
The z.ai GLM coding endpoint intermittently accepts the chat request but never
sends response headers; undici's default 300s headersTimeout then hung the user
for five minutes before failing, and UND_ERR_HEADERS_TIMEOUT was not in the
RetryAgent's retried error set, so there was no recovery.
headersTimeout only bounds time-to-FIRST-headers (before any body) — it is NOT
the streaming budget, so lowering it does not truncate live SSE streams. Cap it
(env AI_HTTP_HEADERS_TIMEOUT_MS, default 60s) so a header stall fails fast, and
add UND_ERR_HEADERS_TIMEOUT to the retried error codes so the stalled request is
retried on a fresh connection (which usually responds in seconds). bodyTimeout
kept generous (env AI_HTTP_BODY_TIMEOUT_MS, default 300s) so slow streams with
sparse chunks survive. UND_ERR_BODY_TIMEOUT is deliberately NOT retried (mid-body,
partial SSE already delivered).

Node's fetch returns a generic "fetch failed" error, hiding the actual
reason (e.g., ECONNRESET, timeout) in the error's cause chain. This
change extracts up to three levels of the cause, formats each with its
code and message, and includes the chain in the warning log, making
failures more actionable.
The streaming chat turn hangs in all browsers while the non-streaming test
endpoint works — both use the same model/transport (createOpenAI + aiFetch),
so the suspect is the streaming path / custom undici RetryAgent transport.
- ai-http.ts: wrap aiFetch with per-request timing logs (start, ms-to-headers
on success, elapsed ms + cause on failure). Chat at info, embeddings at
debug. Only host+path logged.
- ai-chat.controller.ts / ai-chat.service.ts: log turn START, first-chunk
latency, FINISHED duration, and elapsed ms on disconnect/error/abort.
- ai.service.ts: AI_BYPASS_RESILIENT_FETCH=true makes the CHAT model omit
fetch:aiFetch and use the default global fetch — isolates transport vs
request-shape. Chat-only; embeddings/STT untouched; reversible via env.
- .env.example: document the flag.
No timeout/retry change. tsc clean; ai-chat + ai suites pass (292).
Batch of fixes from the automated QA pass on develop. Each was reproduced and
then verified fixed live (browser/curl); logic-bearing fixes have unit tests.
Functional bugs:
- #122 collab-token was capped by the anonymous public-share-AI throttler (5/min);
skip all non-AUTH named throttlers on this auth-guarded, client-cached route.
- #123 editor onAuthenticationFailed threw `jwtDecode(undefined)` and never
reconnected; read the token via a ref, guard the decode (incl. missing exp),
and refetch+reconnect on any auth failure.
- #124 a slash command containing a space ("/Heading 1") inserted literal text;
enable allowSpaces and close the menu when the query matches no items.
- #125 space slug auto-gen produced uppercase initials for multi-word names;
computeSpaceSlug now yields a lowercase alphanumeric slug.
- #126 AI chat window position/size now persisted (atomWithStorage) across reload;
also fixes a latent ResizeObserver-attach bug on first open.
- #127 workspace name update accepted URLs; add @NoUrls (parity with setup).
- #132 icon-columns 4/5 passed calc() into SVG width/height attrs (console spam);
size via style. share-for-page query returns null instead of undefined.
- #134 "Reindex now" counter looked stuck: reindex runs async; the client now
polls coverage (bounded) so the counter climbs live; misleading server comment
reworded.
UX / consistency:
- #128 add success toasts to favorite/label/avatar/member-(de)activate.
- #129 "1 result found" pluralization; hide the single-option Type filter.
- #130 replace raw Zod strings with friendly messages (name/password/group).
- #131 unify "Untitled" casing in tree/breadcrumb/tab; stop force-uppercasing
space-name chips; fix confirm-dialog labels (Cancel / Remove), invite
placeholder typo, Export/Move-to-space labels.
- #133 disable profile Save when clean; toast on unsupported avatar image;
style the invalid-invitation page with a CTA; hide Share for read-only users;
align the dictation "not configured" message; "Go to login page" typo.
Tests: computeSpaceSlug, workspace-name NoUrls DTO, share-query null
normalization, slash getSuggestionItems empty-close.

Outbound LLM calls used Node's default global undici agent (default
keep-alive pooling, no transport-level reconnect), so a TCP RST on a
reused/poisoned keep-alive socket surfaced as
"Cannot connect to API: read ECONNRESET" and failed the chat stream and
title generation after the AI SDK's own retries were exhausted.
Add a dedicated resilient outbound HTTP layer (ai-http.ts): a shared
undici RetryAgent over a tuned Agent, exposed as `aiFetch` and injected
into every AI provider factory (createOpenAI chat/embeddings/STT,
createGoogleGenerativeAI, createOllama) plus the raw JSON STT fetch. The
RetryAgent reconnects on connection-level errors (ECONNRESET, ...) on a
FRESH socket, opts POST into the retry methods (undici's default list
excludes POST), and leaves HTTP-status retries (429/5xx + Retry-After) to
the AI SDK to avoid double-retry.
- ai-http.ts: shared RetryAgent(Agent) + aiFetch (maxRetries 2,
conservative keep-alive, connect timeout, streaming-safe timeouts)
- ai.service.ts: inject fetch: aiFetch into every provider factory
- ai-http.spec.ts: regression test that aiFetch injects the RetryAgent
dispatcher into the underlying fetch

reindexWorkspace isolated every per-page failure, so an invalid/missing
API key (401 "User not found") made all pages fail identically while the
batch kept issuing hundreds of doomed requests against the provider.
Add isFatalProviderError() (401/403 auth, 402 billing) and abort the
whole batch on such errors; 429 rate-limit and embedding timeouts stay
per-page isolated. Adds unit tests for the predicate and a regression
test for the abort/iterate control flow.

Add a per-workspace `sttLanguage` setting (ISO-639-1 hint; empty =
auto-detect) and a searchable language picker in the Voice / STT settings
card. The hint is forwarded to the transcription endpoint:
- multipart path via the AI SDK `providerOptions.openai.language`
- JSON (OpenRouter) path via a top-level `language` body field
only when non-empty, so auto-detect behaves exactly as before.
Threaded through the whole stack: ai.types, update DTO, AiSettingsService
(resolve/getMasked/update), the workspace.repo SQL allowlist, the client
ai-settings service types, and the provider-settings form. Adds en-US
source keys and ru-RU translations.

Provider auth failures were logged with the provider's opaque message only
(e.g. OpenRouter returns "401: User not found." for a bad/missing API key),
which reads like a missing wiki user rather than a credentials problem.
describeProviderError now prepends a clear, human-readable English label for
a small set of well-known HTTP statuses while keeping the original detail
(status + provider message + truncated response-body snippet):
- 401/403 -> authentication failed (invalid or missing API key)
- 402 -> insufficient credits or quota
- 429 -> rate limit exceeded
Other statuses and status-less errors are formatted exactly as before. The
label is a static string and never contains the API key. Benefits every
caller (embedding processor, indexer, AI "Test endpoint" UI) at once.
Tests: switch the plain status+message case to a non-classified status (500);
add 401/403/402/429 cases; keep 502/503 as regression guards for the
unchanged path.
Relocate resolveTrustProxy from main.ts (untestable — bootstraps on import) to
integrations/environment/trust-proxy.util.ts and import it back. Unit-test every
branch (empty/undefined -> safe loopback/private default; true/false; hop count;
trim; CIDR/negative passthrough) so a regression can't silently re-open the XFF
spoofing hole (#61).

Deduplicate the "save a workspace setting" plumbing shared by HtmlEmbedSettings
and TrackerSettings (workspace atom read, isLoading state, updateWorkspace + atom
merge forcing settings[key], success/error notifications) into a new
feature-scoped hook useWorkspaceSetting(key).
- Each component keeps its own interaction model: html-embed is an optimistic
toggle with revert-on-failure; tracker is edit-then-save on an explicit button.
- Unify error handling on the better pattern: surface err.response?.data?.message
and use console.error (html-embed previously used console.log + a generic message).
No user-facing behavior change; client typecheck clean.
Test-coverage follow-ups (untested trackerHead injection in ShareSeoController and
the no-op audit branch) tracked in #100.
isBlocked was checked synchronously but recordFailure ran only AFTER the bcrypt
awaits, so N concurrent /mcp Basic requests for one email all slipped past the
threshold. Add FailedLoginLimiter.tryReserve (atomic synchronous check+increment)
+ release (undo), and reserve all 3 keys BEFORE any await so the (threshold+1)-th
concurrent attempt is rejected before its bcrypt runs. The reservation IS the
failure record (post-await recordFailure removed -> counted exactly once). Non-
credential early throws (missing workspace, SSO/MFA gate) and business errors
release the reservation so they don't burn a victim's budget; success clears.
Tests prove login() runs exactly threshold times under concurrency and that
gate/config rejects don't consume budget.

McpService.enforceBasicLoginGate re-implements AuthController.login's pre-token
SSO/MFA gate; silent drift would re-open the bypass. Add an AST contract test
(comments stripped) asserting BOTH method bodies contain validateSsoEnforcement,

side fails CI. Test-only (no core/auth refactor).

The 4-step html-embed gate (feature-enabled AND role-allowed -> stripHtmlEmbedNodes)
was replicated across call-sites, pinned only by brittle source-regex tests. Add
stripHtmlEmbedIfNotAllowed(json, {featureEnabled, role, onStrip}) and migrate the
5 plain strip-all sites (collab handler, page create+duplicate, both import paths,
transclusion) to it, each keeping its own feature/role resolve + log via onStrip.
Left the 2 sites with different semantics: persistence.extension (#29 preserve-
admin) and share.service (feature-only kill-switch, no role gate). Real unit tests
replace the regex pins; behavior identical.
