Approve-with-comments re-review; no blockers. All 7 actionable points (8 is a
forward-looking architecture note — recommendation A, keep as-is):
1. chat-markdown.util spec: restore parity coverage of the removed client spec —
tool error state (+ errorText), unknown-tool fallback (`Ran tool <name>` en /
`Выполнил инструмент <name>` ru), and the circular-output stringify catch.
2. findAllByChat row cap is now testable (injectable limit) + an int-spec proves
truncation on a modest volume.
3. Stability: the per-step durability updates are SERIALIZED via a promise chain
(stepUpdateChain) so they commit in step order — onlyIfStreaming already
closed the finalize race, this closes inter-step ordering.
4. findAllByChat keeps the NEWEST messages on truncation (order DESC + reverse,
like findRecent) and logs a warning with chatId, instead of silently dropping
the newest tail.
5. The LABELS parity comment already references the real path (tool-parts.tsx /
toolLabelKey) — confirmed accurate.
6. Removed the redundant 'off-by-one boundary' test (strict subset of the two
adjacent prepareAgentStep cases).
7. Extracted the terminal-finalize dispatch into a shared `applyFinalize`, used
by BOTH the service's finalizeAssistant and its test — the test now exercises
the real path, not a copy, so a production drift fails it.
Verified: server build + 325 ai-chat unit + 6 integration; prettier clean.

15-point review of the persistent-history PR. Architecture decisions: crash
recovery = recency threshold; tool-label duplication = leave as-is.
Must-fix:
1. Boot-sweep bounded by recency. sweepStreaming now also requires
`updatedAt < now() - SWEEP_STREAMING_STALE_MS` (10 min), so a fresh replica's
startup sweep can't abort a turn another replica is actively streaming
(multi-instance deploy). Int-spec: a FRESH 'streaming' row is NOT swept, a
STALE one IS.
2. Restore export during the FIRST streaming turn of a new chat (#174). The
server chatId is now adopted EARLY (in-place, on the start-chunk metadata) via
a new `onServerChatId` callback wired through use-chat-session → chat-thread,
so `activeChatId` is set at turn start and the Copy button is live mid-first-
turn (canExport = !!activeChatId). Hook tests for early/in-place/no-op adopt.
3. Cover finalizeAssistant's fallback-insert branch: extracted pure
`planFinalizeAssistant(assistantId)` (update when id present, insert when the
upfront insert failed) + a dispatch harness test for both arms.
Tests: onModuleInit lifecycle spec (sweep called; throw → resolves + warns);
int-spec updatedAt assertion → toBeGreaterThan.
Cleanups: cap findAllByChat at 5000 rows; upfront-insert-failure log carries
chatId+workspaceId; removed the now-dead buildPartialAssistantRecord (only the
spec consumed it; shapes still pinned by the flushAssistant suite); controller
passes `lang: dto.lang` (normalizeLang handles undefined); dropped a no-op
`?? undefined` in errorOf; documented the content-column semantics change
(concatenated step text, UI renders from metadata.parts); CHANGELOG [Unreleased]
entry (#183, #174); reworded the stale LABELS parity comment.
Verified: server build + 323 ai-chat unit + 5 integration; client tsc + 160
ai-chat unit; prettier clean.

8-point multi-aspect review of the batch PR; security/regressions were clean.
1. Lease leak: the #180 reorder moved `toolsFor` (which leases external MCP
clients, refCount+1) ahead of buildSystemPrompt + forUser, but the only
release (closeExternalClients) was bound to the streamText callbacks. A throw
in between leaked the lease (refCount stuck, undici sockets held until
restart). Define closeExternalClients right after the lease and wrap
buildSystemPrompt+forUser in try/catch that closes-then-rethrows.
2. Cover the patch_node/delete_node dup-id refusal (#159#6): extract the guard
into a pure `assertUnambiguousMatch` (node-ops) and unit-test 0/1/>1.
3. Regress the body-before-title order (#159#10): mock-HTTP test (collab fails
fast against a server with no WS upgrade) asserts /pages/update (title) is
NEVER posted when the body write fails — for updatePage AND updatePageJson.
4. CHANGELOG [Unreleased]: #180, #168 (Added); #163 (Fixed).
5. Add the missing en-US i18n keys (Back to references / {{label}}).
6. Drop the duplicate content/empty/blank cases in ai-chat.prompt.spec.ts (they
repeat the buildMcpToolingBlock unit tests); keep only sandwich placement +
both-safety-copies.
7. CI Postgres pg16 -> pg18 (match docker-compose).
8. jsonb decode seam: shared `parseJsonbValue(value, guard)` in database/utils.ts
holds the legacy double-encoding self-heal in one place; parseToolAllowlist /
parseModelConfig keep only a type-guard.
Verified: server build + 124 unit + 15 integration; mcp 311; prettier clean.

Admins can now give each EXTERNAL MCP server a free-text instruction ("how/
when to use this server's tools") that the agent receives in its SYSTEM
PROMPT next to the tool descriptions — porting the built-in SERVER_INSTRUCTIONS
idea to admin-configured servers. Trusted, admin-authored text (like a system
prompt); NON-secret, so unlike headersEnc it IS returned in views/forms.
- Migration: nullable `instructions text` on ai_mcp_servers (old rows = null =
no guidance). Table type + repo insert/update (blank/whitespace -> null via
blankToNull). DTO `@MaxLength(4000)`. Service threads it through
McpServerView/toView.
- mcp-clients: `McpServerInstruction { serverName, toolPrefix, instructions }`
threaded through the toolset/cache/lease. Guidance is built ONLY for a server
that actually connected AND contributed >=1 callable tool (the allowlist may
filter all of them out) AND has non-blank text — so a guide never appears for
tools the agent cannot call. Cached with the toolset, so an edit is picked up
next turn via the existing CRUD cache invalidation.
- System prompt: `buildMcpToolingBlock` renders an <mcp_tooling> block INSIDE
the safety sandwich (after context, before the trailing SAFETY_FRAMEWORK) so
it informs tool choice but cannot override the rules; each section is headed
by the server's `prefix_*` namespace. Empty/blank -> block omitted. The
caller (ai-chat.service) now builds the external toolset BEFORE the prompt and
passes external.instructions; client-handle lifecycle (close-once) unchanged.
- Client: instructions field in types + a Textarea (autosize, maxLength 4000)
in the MCP-server form with a namespace-prefix hint; i18n (en/ru).
Tests across every layer (prompt block placement + both SAFETY copies; view
blank->null; buildEntry includes guidance only for connected+>=1-tool+non-blank;
DTO MaxLength; repo + integration round-trip; service wiring). Delegated impl
reviewed (APPROVE); applied the import-type follow-up.

PR #172 fixed the jsonb double-encoding for `tool_allowlist` but the same
class of bug, and the same re-derived workaround, remained elsewhere.
1. model_config (agent roles): jsonbObject still used the buggy `::jsonb`
bind, so `ai_agent_roles.model_config` round-tripped as a jsonb STRING
SCALAR. The read-path `typeof === 'object'` check then failed and the
model override was SILENTLY dropped (role fell back to the default model).
Fixed to `::text::jsonb` and added `parseModelConfig` + `normalizeRow` so
every read self-heals already-corrupted rows (no migration).
2. Centralized the write workaround as `jsonbBind()` in database/utils.ts —
one implementation with one explanation of the quirk — replacing the
per-repo `jsonbArray` (mcp) and `jsonbObject` (roles).
3. Integration coverage (the fix is a DB round-trip a unit test cannot see;
the read-side parser MASKS a write regression): new
ai-mcp-server-repo.int-spec asserts `jsonb_typeof(tool_allowlist)='array'`
after insert + heals a seeded string-scalar row; ai-agent-roles-repo
int-spec gains the same for `model_config` (`'object'` + heal).
4. Updated the stale `ai-mcp-servers.types.ts` comment (the driver returns a
JSON string for legacy rows; the repo normalizes every read).
5. Fail-open logging: a corrupt tool_allowlist degrades to "no restriction"
(agent gets ALL tools) — normalizeRow now warns (server id only, never
contents) so the silent widening leaves a trace.
6. Simplified parseToolAllowlist (normalize the string once, then a single
array-of-strings check) — identical behaviour, all 12 cases still pass.

Review caught a real race: onStepFinish fires `updateStreaming()` fire-and-
forget (not awaited), so the FINAL step's streaming UPDATE and the terminal
`finalizeAssistant` UPDATE run as two concurrent statements on different pool
connections — commit order is not guaranteed. If the late streaming update
lands AFTER finalize, the completed row is clobbered back to status='streaming'
with no usage/finishReason, and the next startup sweep then mis-marks the
finished turn 'aborted'. Green unit/integration tests don't reproduce a
cross-connection race.
Fix: scope the per-step update with `onlyIfStreaming` → SQL `WHERE
status='streaming'`. Once finalize has set a terminal status the late update
matches zero rows and no-ops, regardless of commit order; finalize runs
unguarded so it always wins. A cheap `if (finalized) return` short-circuit
avoids most wasted queries, but the SQL guard is the authoritative fix (the
flag can be set after a query is already in flight).
Integration test: finalize to 'completed', then a late onlyIfStreaming update
is a no-op — status/content/usage preserved.

The chat lived in inconsistent paradigms (in-memory stream + client export vs.
DB-as-context), which made export flaky and lost the assistant answer if the
process died mid-turn. Make the DB the single source of truth.
A. STEP-GRANULAR DURABILITY (server)
- ai_chat_messages gains a nullable `status` column (migration; NULL = legacy =
completed). The assistant row is now INSERTED UPFRONT as `status:'streaming'`
and UPDATEd on every onStepFinish with all finished steps (text + tool calls +
tool RESULTS), then finalized once to completed/error/aborted on the terminal
callback. So a process death mid-turn keeps every finished step; a startup
sweep (OnModuleInit → sweepStreaming) flips any dangling 'streaming' row to
'aborted'. The write path no longer depends on a live socket.
- Pure exported `flushAssistant(steps, inProgressText, status, extra?)` builds
the persist payload (metadata.parts byte-identical to the old builder), so a
future background worker can call the same path. AiChatMessageRepo gains
`update`, `sweepStreaming`, and `findAllByChat`.
- consumeStream drain, external-MCP client close-once, SSE heartbeat preserved.
B. SERVER-SIDE EXPORT
- New pure `chat-markdown.util.ts` renders Markdown from DB rows ONLY (server
port of the client builder). Because A persists the in-progress row, the
export now includes an interrupted turn up to its last finished step (flagged
"still generating"). `POST /ai-chat/export` (owner-gated via assertOwnedChat,
workspace-scoped) returns it; `lang` accepts a full client locale tag
('en-US'/'ru-RU') and is normalized server-side (normalizeLang) — a strict
@IsIn(['en','ru']) DTO rejected the real client's i18n.language with a 400,
caught in real-browser testing.
- Client: handleCopy calls the endpoint; `canExport = !!activeChatId`. The whole
liveThreadRef/liveStateRef/onLiveContentChange/hasLiveContent hybrid (and the
client chat-markdown util + test) is removed — the server is now authoritative.
Tests: flushAssistant unit (status shapes + parts parity), chat-markdown.util
unit (incl. legacy NULL-status + interrupted note + ru + normalizeLang locale
tags), controller export wiring + owner-gate, integration update/sweepStreaming.
Verified: server build + 318 ai-chat unit + 3 integration; client tsc + 157
ai-chat unit; and END-TO-END in a real browser — a chat turn persists mid-stream
and the Copy button exports the DB-sourced markdown (showing the in-progress
row), HTTP 200 after the locale fix.

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.

Opening the edit form for an MCP server that has a saved tool allowlist crashed
the whole settings page (`TypeError: Ke.map is not a function` in Mantine) — and,
worse, the allowlist was silently NOT enforced. Both stem from one root cause:
the `tool_allowlist` jsonb column round-trips as a JSON STRING, not an array.
Root cause: `jsonbArray` bound `JSON.stringify(value)` (already a JSON string)
straight to a `::jsonb` cast. node-postgres infers the param type as jsonb and
JSON-stringifies it a SECOND time, so the column stored a jsonb STRING SCALAR
(`"[\"a\"]"`, jsonb_typeof = string) instead of an array. On read the driver
hands back the JS string `'["a"]'`. Then:
- the edit form's TagsInput called `.map` on a string -> page crash;
- mcp-clients did `Array.isArray(allow)` -> false for a string -> fell through
to "no restriction" and exposed ALL of the server's tools.
Fix (both verified on the stand):
- Write: `jsonbArray` casts `::text::jsonb` so the param is bound as text (sent
verbatim) and parsed into a real jsonb array. New rows now store
jsonb_typeof=array.
- Read: `normalizeRow` runs every fetched row through `parseToolAllowlist`, which
returns `string[] | null` for both shapes (already-array passes through; a JSON
string is parsed; null/invalid -> null). This REPAIRS existing double-encoded
rows on read, so the UI and the allowlist enforcement work without a data
migration. Applied in findById / listByWorkspace / listEnabled.
- Client: defensive `Array.isArray(...) ? ... : []` guard in the form so a bad
shape can never take the settings page down again.
Tests: ai-mcp-server.repo.spec (8 cases for parseToolAllowlist — array, the
JSON-string read, null, empty, non-array json, unparseable, non-string elements,
non-string primitive). mcp-servers-to-view + mcp-namespacing still green.
Verified live: an old double-encoded row now reads as an array; a newly created
server stores jsonb_typeof=array.

Review of #156 (Request changes) flagged the new CLIENT logic as untested. Extract
the decision logic from chat-thread.tsx into pure, unit-testable helpers and cover
both branches the reviewer called out:
- `roleLaunchMessage(role, default)` — the three-way handleRolePick behavior:
autoStart=false -> null (send nothing); autoStart=true + custom -> trimmed
message; autoStart=true + empty/null/whitespace -> default fallback.
- `shouldResetRolePicked(chatId, roleId, flag)` — the #149 render-phase reset; the
regression test asserts the stuck-flag case (New chat after an autoStart=false
pick -> cards return) that the pre-fix code never handled, and that a still-bound
role keeps the cards hidden.
chat-thread.tsx now calls these helpers (behavior unchanged). 9 new pure tests.
Also folded the review's cosmetic suggestion: `x ? x : null` -> `x || null` in
ai-agent-roles.repo.ts (identical for string|null|undefined).
Client tsc clean; role-launch + role-cards green; repo spec green.

Agent role cards always auto-sent a hardcoded "Take a look at the current
document" on pick. Make it configurable per role:
- autoStart (bool, default true): whether picking the role auto-sends a message.
- launchMessage (nullable text): the text sent on auto-start; empty -> the
built-in default. autoStart=false -> bind the role and send nothing (the user
types the first message, which still carries the roleId).
Existing roles default to autoStart=true / launchMessage=null => identical old
behavior.
Full-stack:
- migration 20260624T120000 adds `auto_start boolean NOT NULL DEFAULT true` +
`launch_message text` (additive; down drops both); db.d.ts updated by hand.
- DTO: autoStart (@IsBoolean) + launchMessage (trim @Transform, @MaxLength 2000).
- repo/service: thread + normalize (undefined=unchanged, ""=>null, autoStart??true).
Both fields exposed in the picker-view for ordinary members (they decide
whether/what to auto-send); instructions/modelConfig stay ADMIN-ONLY.
- client: IAiRole types, role form (Switch + Textarea, re-hydrated on edit),
handleRolePick branches on autoStart; i18n en-US + ru-RU.
Review follow-ups folded in: reset the `rolePickedNoSend` flag when the thread
returns to an empty role-less state (the "New chat after autoStart=false pick"
stuck-UI bug — render-phase one-shot reset); made create/update launchMessage
normalization symmetric (raw value, server normalizes ""→null).
Server: 68 role tests pass, tsc clean. Client: tsc clean, role tests pass.

Resolves the open items from the latest PR #143 code review:
- test(page): cover the four agentSourceFields stamp sites (create, update,
movePage, movePageToSpace) with agent + normal-user payload assertions;
add findById({ includeIsAgent: true }) wiring guards to the JWT and collab
auth-seam specs so a future drop of the option is caught.
- fix(privacy): drop `isAgent` from UserRepo.baseFields and gate it behind a
new opt-in `findById({ includeIsAgent })`, requested only by the two auth
seams that derive provenance — stops the flag leaking via the workspace
member list and generic user payloads.
- docs: correct the agentSourceFields JSDoc and the two UPDATE-site comments
to distinguish INSERT (omitted column → DB default 'user') from UPDATE
(omitted column → existing value kept, Kysely writes only present keys).
- style(page): collapse three stray double blank lines left by an earlier edit.

Mark comments (and, via existing page provenance, pages) created under an
is_agent service account as authored by AI, derived from the SIGNED server
identity rather than any client field, and render the existing AI badge in
the comments sidebar.
Backend (B1):
- Add additive users.is_agent boolean (default false) migration; reflect in
the Users Kysely type, the user repo baseFields, and (via Selectable) the
User entity.
- jwt.strategy: derive req.raw.actor from user.isAgent (an is_agent account
stamps every write 'agent'); external MCP has no internal ai_chats row so
aiChatId stays null. Non-spoofable: a plain user cannot obtain
created_source='agent'.
- Loosen the provenance aiChatId type to string|null across token.service and
the JwtPayload/JwtCollabPayload claims (type-level only; the internal AI-chat
path still passes a real aiChatId).
Frontend (B2):
- Extend IComment with createdSource/aiChatId/resolvedSource (backend already
returns them via selectAll).
- Extract the local AiAgentBadge from history-item into a shared
components/ui/ai-agent-badge.tsx (clickable deep-link when aiChatId present,
plain label when null/absent); reuse it in history-item and render it in
comment-list-item next to the author name when createdSource==='agent'.
Tests: comment.service agent/null-aiChatId provenance, jwt.strategy provenance
derivation + anti-spoof, AiAgentBadge clickable/non-clickable branches, and
comment-list-item badge render/no-render.

Each chat row in the AI-chat history now shows a dimmed second line with
how long ago the chat was created and the document it was created in
("N ago / <document>", or "No document" when started outside a page).
Server:
- New migration: nullable ai_chats.page_id (FK pages.id, ON DELETE SET NULL).
- Capture the origin page at chat creation from the client-supplied openPage,
but validate it first: it must be a real page in the same workspace that the
user may read (PageAccessService.validateCanView), else null. This keeps the
"openPage.id is attacker-controllable but harmless" invariant - preventing a
cross-workspace/cross-space page-title leak and a post-hijack FK crash.
- findByCreator left-joins pages (scoped by workspace, defense-in-depth) and
returns pageTitle.
Client:
- IAiChat gains pageId/pageTitle; ConversationList renders a ChatMetaLine
(useTimeAgo + origin document) as a dimmed second line.
- Add i18n key "No document" (en-US, ru-RU).

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.

resolveRoleForRequest and resolveShareRole duplicated the security invariant
'role exists, not soft-deleted, enabled, workspace-scoped, else null'. Move it to

derivation + null handling. (describeProviderError half of #95 was done earlier.)

handleMessage became a no-op and PageWsListener intentionally ignored
PAGE_UPDATED, so a rename/icon change (client operation:updateOne) was no longer
rebroadcast -> other clients saw stale title/icon in the sidebar+breadcrumbs
until a reload (create/duplicate/restore were covered; updateOne regressed).
Add a server-authoritative onPageUpdated handler: PageService.update detects a
real title/icon change (DTO carries the field AND value differs; no-op/content-
only saves excluded) and attaches a treeUpdate snapshot to PAGE_UPDATED; the
listener broadcasts a tree updateOne via the restriction-aware emitTreeEvent
(so a restricted page's title never leaks). Content-only saves attach nothing.

Resolve conflicts from the parallel page-embed refactor that landed in develop
via #49:
- page-embed-view.tsx: keep develop's canonical decideEmbedState for the
cycle/depth/availability guard; keep #45's #39 chrome cleanup (single source
link, IconFileText fallback) and #40 refresh remount key. Drop #45's now-unused
isPageEmbedCycle/isPageEmbedTooDeep wiring.
- page-embed-picker.tsx: use develop's excludeHost util; drop #45's duplicate
filterPageEmbedOptions and its test.
- page-embed-ancestry-context.test.tsx: keep #45's superset suite.
- page-template-access.spec.ts: keep develop's constructor args; update the two
deleteByReferenceAndSources assertions to the new 4-arg workspace-scoped
signature introduced by #45 (#36 defense-in-depth).
Full suite green: server 624, client 219, editor-ext 56, mcp 247.

Add ~330 tests across server (Jest), client (Vitest), editor-ext (Vitest)
and packages/mcp (node:test) for the gitmost features added since
053a9c0d: AI chat, AI agent roles, public-share assistant, MCP per-user
auth, HTML embed, page templates/embed, realtime tree, tree
expand/collapse, and the AI-settings UI.
Test-tooling fixes (prerequisite, were silently hiding coverage):
- Repair 3 page-template specs broken by the 11-arg TransclusionService
constructor; they never compiled, so template access-control / content
-leak / unsync-strip coverage was fictitious.
- Build @docmost/editor-ext before server tests via a `pretest` hook;
the stale dist omitted the new HtmlEmbed/PageEmbed exports (TS2305).
- Let jest resolve the .tsx email templates: add `tsx` to
moduleFileExtensions and widen the ts-jest transform to (t|j)sx?.
Behaviour-preserving "extract pure core" refactors that the tests drive:
- server: resolveShareAssistantRequest + uiMessageTextLength
(public-share controller), decideBasicGate + mapAuthResultToResponse
(mcp), buildErrorAssistantRecord (ai-chat), jsonbObject export (roles).
- client: render-raw-html + shouldExecute/canEdit, decide-embed-state,
page-embed picker utils, tree-socket reducers, open/close branch maps,
isEndpointConfigured/resolveKeyField; buildTreeWithChildren now treats
a permission-trimmed orphan as a root instead of crashing.
Deferred (need a test DB or HTTP harness, documented in the specs):
repo-level Postgres integration tests and the public-share XFF E2E.
Pre-existing DI/lib0-ESM suite failures are untouched and out of scope.

Consistency hardening from #17 review (not currently exploitable):
- toggleTemplate now explicitly rejects a page outside the caller's workspace
(page.workspaceId !== user.workspaceId -> NotFound, avoiding existence leak)
instead of relying solely on the space-membership model.
- PageTemplateReferencesRepo.deleteByReferenceAndSources is now workspace-scoped
(adds a workspaceId filter + param), matching the 'scope by workspaceId
everywhere' invariant; the sole caller threads its workspaceId.
The PAGE_TEMPLATE_THROTTLER limit is intentionally left as-is (the issue's
throttle item was 'consider only'; no change without usage data).

The 'used in N pages' reverse-navigation method had zero callers in the merged
PR #17 — unreachable, untested code. Remove it. The reverse-navigation feature
can be (re)added with the method if/when it's actually built.

Anonymous public-share AI assistant:
- Add a workspace setting `publicShareAssistantRoleId` so an admin can pick which
agent role (identity/persona) the anonymous assistant adopts. The role's
instructions REPLACE the built-in persona while the immutable safety framework
is still always appended; the role's optional model override takes precedence
over the cheap publicShareChatModel. Resolved server-authoritatively
(workspace-scoped, soft-delete aware; disabled/missing roles fall back to the
built-in persona, so the tool scope remains the real security boundary).
- Plumb the field through the update DTO, ai-settings service, the workspace.repo
ALLOWED whitelist, resolve()/getMasked(), stream-time role resolution and the
prompt/model, plus the settings UI: a new "Assistant identity" Select listing
enabled roles (and surfacing a saved-but-disabled role explicitly).
Public-share branding / floating icon:
- Fix the AI assistant FAB overlapping the "Powered by ..." button (both were
Affixed bottom-right): stack the FAB above the bottom-right branding.
- Rename "Powered by Docmost" -> "Powered by Gitmost" and point the link at the
gitmost repo.
Tests: extend public-share-chat.spec (role persona replacement still appends the
safety framework, resolveShareRole edge cases, model-override precedence).

The admin-only raw HTML/JS embed is a deliberate stored-XSS surface, so gate the
whole feature behind a workspace toggle that is OFF by default; it only works
when a workspace admin explicitly enables it.
- settings.htmlEmbed (boolean, default false) + workspace-update field htmlEmbed,
persisted via WorkspaceRepo.updateSetting with an audit diff. Flipping it is
admin-only (same Manage Settings CASL as other workspace toggles).
- New gate htmlEmbedAllowed(featureEnabled, role) = featureEnabled && admin/owner.
All 7 server write paths (create, duplicate, collab onStoreDocument, REST/MCP/AI
updatePageContent, single + zip import, transclusion unsync) now read the
workspace's settings.htmlEmbed and strip unless (toggle ON AND admin). OFF
(default, or a failed/empty workspace lookup) strips htmlEmbed for EVERYONE
including admins -> existing embeds are cleaned up on next save, none persist.
- Client (defense-in-depth): the /html slash item is hidden unless toggle ON +
admin; the NodeView executes nothing and shows a 'disabled in this workspace'
placeholder when OFF; an admin Switch in Workspace Settings -> General with a
description of the behavior.
- docs/html-embed-admin.md documents the toggle + admin-only + fail-closed
coedit (a non-admin save strips an admin's embed) + execution semantics.

Resolve conflicts with the independently-merged ai-agent-roles feature:
- ai-chat.module.ts: keep BOTH AiAgentRolesModule and the public-share
wiring (Share/Search modules, PublicShareChatController, services).
- ai.service.ts: take develop's getChatModel ChatModelOverride superset,
which already covers the public-share model-id-only override.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
Follow-up fixes on the agent-roles feature:
- ai.service: a cross-driver override to the ollama driver (when the
workspace driver is not ollama) now fails with an explicit 503 instead
of silently reusing the workspace base URL, which belongs to a different
provider. Same-driver ollama and openai/gemini overrides are unchanged.
- migration: add a partial unique index on (workspace_id, name) WHERE
deleted_at IS NULL so role names are unique per workspace without
soft-deleted rows blocking re-creation; map Postgres 23505 to a 409
ConflictException on create/update.
- dto: validate the role id as @IsUUID instead of @IsString.
- roles list: do not expose instructions/modelConfig to non-admin members.
The list endpoint now returns a picker view (id/name/emoji/description/
enabled) to members and the full view only to admins (same gate as the
CRUD endpoints). Client IAiRole fields made optional accordingly.
Adds tests for the cross-driver-ollama throw, the 23505->409 mapping, and
the non-admin picker-view security invariant.

Integrate the already-merged step-limit work from develop. Only conflict was
ai-chat.service.spec.ts: both sides appended a describe block and edited the
import line. Resolved as a union — keep compactToolOutput + the assistantParts/
serializeSteps/rowToUiMessage suites (this branch) AND the prepareAgentStep
suite (develop), importing all symbols from ai-chat.service.

Unit tests for the safety-critical paths: crypto secret-box (round-trip,
tamper detection, wrong key), the SSRF guard (blocked ranges + DNS-rebinding),
the ai-chat tools service, the page-embedding repo, and the
assistant-parts/serialization helpers. Those server helpers (assistantParts,
rowToUiMessage, serializeSteps) are exported ONLY for the tests — no runtime
change.
Also: keyboard a11y on the chat history header and conversation rows
(role/tabIndex/Enter+Space), and DRY refactors that move shared logic into one
place (isToolPart -> tool-parts util; buildInitialValues in the MCP form).
The behaviour-changing edits that previously rode along in this commit are
split out into the following two commits, per review.

Release-cycle test audit found the role feature's security-critical paths
untested. Adds real unit tests (against the actual functions):
- resolveRoleForRequest invariants: role comes from chat.roleId not body.roleId
(no per-turn swap), lookup scoped to workspace.id, disabled/soft-deleted role
-> null, new-chat uses body.roleId, stale chatId falls back.
- CASL admin gate: non-admin create/update/delete -> Forbidden and service not
called; admin delegates with workspace.id; list() is member-reachable.
- roleModelOverride: unknown driver dropped (never reaches getChatModel's
throwing default), valid override passes through, blanks ignored.
- getChatModel override success path (cross-driver fetch + decrypt; chatModel-
only reuse), and service update/remove cross-workspace 'not found' guards +
modelConfig tri-state.
Tiny fix: findByCreator badge left-join now also requires enabled=true, so a
disabled role (downgraded to universal by resolveRoleForRequest) no longer shows
a misleading chat-list badge.

Embed another page's LIVE content into a host page (it updates when the source
changes, not a static copy). A page can be flagged a template for discovery in
the picker; any accessible page can be embedded.
Server:
- migrations: pages.is_template (+ partial index) and page_template_references
(whole-page back-refs); db.d.ts/entity types hand-merged (db.d.ts is curated).
- POST /pages/toggle-template (CASL Edit) flips is_template; is_template is
returned by findById + the sidebar tree select so the tree menu label
reflects state. Search suggestions gain an onlyTemplates filter for the picker.
- POST /pages/template/lookup ({sourcePageIds[]}, <=50): returns each accessible
source's {title, icon, slugId, content, sourceUpdatedAt} with comment marks
stripped (same access path as transclusion: filterViewerAccessiblePageIds;
inaccessible -> no_access, missing -> not_found; error path -> not_found, never
raw content).
- reference sync (collectPageEmbedsFromPmJson + syncPageTemplateReferences) on
the Yjs save hook; duplicatePage remaps pageEmbed.sourcePageId + inserts refs.
Known MVP gap: REST content updates don't resync refs (lookup uses in-doc ids).
Client:
- pageEmbed node (editor-ext, registered in BOTH client + server schemas);
read-only NodeView with a batching lookup; '/Embed page' slash + template
picker (self-embed prevented); 'Make/Unset template' in the tree node menu.
- Cycle guard: an ancestry-chain context + depth cap (5) render a 'circular
embed' placeholder instead of recursing.
- Public shares show a placeholder (no public lookup in MVP).
MVP excludes (follow-ups): public-share lookup, unsync->static copy, server-side
expansion for export/RAG, MCP schema mirror, point-in-time snapshots.
Implements docs/page-templates-plan.md (MVP, variant A).

The sidebar page tree only updated on other clients when a change was made
via the UI tree, in an open tab, within a ~50ms client relay window — API/MCP/
AI/import changes never propagated. Move the source of truth to the server.
Server:
- Enrich PageEvent with thin TreeNodeSnapshot(s) so the WS listener never reads
the DB (avoids the in-transaction visibility race). insertPage fills the
create snapshot from its returning() row; removePage ships only the deleted
subtree ROOT (client treeModel.remove drops descendants); restorePage carries
spaceId.
- New PAGE_MOVED event from movePage with old/new parent + position + snapshot
(generic PAGE_UPDATED stays for content/rename).
- WsService.emitTreeEvent mirrors emitCommentEvent (per-space restriction gate:
spaceHasRestrictions -> hasRestrictedAncestor -> broadcastToAuthorizedUsers);
author NOT excluded so non-UI creators see their own page (receiver is
idempotent).
- WsTreeService.broadcastPageCreated/Deleted/Moved + broadcastRefetchRoot;
new PageWsListener (create/delete/move/restore) registered in WsModule.
Client:
- Remove the client relay (emit + setTimeout(50)) from create/move/delete;
keep optimistic local updates. Make the optimistic create insert id-idempotent
(find-then-skip) so the now-fast server addTreeNode broadcast can't race it
into a duplicate row. addTreeNode inserts by fractional position among loaded
siblings (consistent order across clients).
Restore uses refetchRootTreeNodeEvent (robust for subtree re-attach). Rename/icon
updateOne and cross-space move realtime are deferred (commented as follow-ups).
Implements docs/backlog/realtime-tree-server-authoritative.md.

Lets an unauthenticated viewer of a published share ask an AI scoped strictly
to that share's page tree. The authenticated agent is untouched; the security
boundary is the tool scope (no identity), and nothing is persisted.
Server:
- workspace toggle settings.ai.publicShareAssistant (default off) +
optional settings.ai.provider.publicShareChatModel (cheap model id; reuses
the chat driver/baseUrl/key). getChatModel(workspaceId, override) substitutes
only the model id, falling back to chatModel.
- POST /api/shares/ai/stream (@Public, SSE). Guardrail funnel, each failing
before streaming: toggle off -> 404; share missing/wrong-workspace/sharing
off -> 404; pageId not in share tree -> 404; provider unconfigured -> 503;
per-IP (5/min) and per-workspace (300/h, IP-independent) rate limits -> 429.
Uniform 404s never confirm a private page's existence.
- forShare read-only in-process toolset: searchSharePages (existing shareId
FTS branch, no spaceId/userId), getSharePage (getShareForPage gate +
share.id check, content via the public sanitizer), listSharePages. No write/
comment/history/cross-space/external-MCP tools.
- Locked share system prompt + immutable safety block; stepCountIs(5).
- /shares/page-info exposes an aiAssistant flag (gated behind isSharingAllowed).
Client: an ephemeral, text-only Ask-AI widget on the public shared page,
shown only when the flag is set; useChat -> /api/shares/ai/stream,
credentials omit. Admin toggle + model field in Settings -> AI.
Also adds a jest moduleNameMapper for src/-rooted imports (fixes pre-existing
unresolvable specs; additive).
Implements docs/public-share-assistant-plan.md.

Reusable, workspace-shared agent roles for the built-in AI chat. A role is
a named persona (system-prompt instructions) + optional model override; a
chat is bound to a role at creation and applies it every turn.
Backend:
- migration 20260620T120000: ai_agent_roles table + ai_chats.role_id
(FK ON DELETE SET NULL); hand-merged types into db.d.ts/entity.types.ts
(db.d.ts is hand-curated here, full codegen would clobber it).
- core/ai-chat/roles: CRUD module. list = any workspace member; create/
update/delete = admin (Manage Settings ability, like ai-settings/mcp).
All repo queries scoped by workspace_id; soft-delete (deleted_at).
- buildSystemPrompt gains roleInstructions: role REPLACES the persona base
(admin prompt / DEFAULT_PROMPT) but SAFETY_FRAMEWORK + context are always
still appended.
- stream(): role resolved from ai_chats.role_id for existing chats (never
the request body -> no per-turn role swap); body.roleId only on creation.
Disabled (enabled=false) and soft-deleted roles fall back to universal.
- getChatModel(workspaceId, override): role model_config can swap model id /
driver; a driver without configured creds throws 503 with a clear message
naming the driver+role, resolved BEFORE response hijack.
Client:
- new-chat role picker (enabled roles only, default Universal assistant),
roleId sent only on the first message; role badge (emoji+name) in the chat
header and conversation list; admin Agent-roles management section in
Settings -> AI (add/edit/delete, MCP-form pattern).
Tests: ai-chat.prompt.spec (role layering + safety always present, incl.
jailbreak); ai.service.spec (override on unconfigured driver -> 503).
Implements docs/ai-agent-roles-plan.md.

Adds a server-authoritative whole-tree endpoint and sidebar menu commands
so a deep space tree can be expanded in one request instead of a per-level
BFS storm.
Server:
- POST /pages/tree (SidebarPageTreeDto: spaceId | pageId), same CASL space
scoping as /sidebar-pages. Returns the whole space tree / subtree as a flat
list in the sidebar item shape (id, slugId, title, icon, position,
parentPageId, spaceId, hasChildren, canEdit), ordered by position
(collate C byte order), content never fetched.
- page.service.getSidebarPagesTree reproduces getSidebarPages' two-branch
permission model: open space -> spaceCanEdit; restricted space -> seed the
full descendant set then prune via filterAccessibleTreePages +
filterAccessiblePageIdsWithPermissions (keeps restricted-but-granted pages,
prunes inaccessible subtrees). hasChildren is derived from the final
filtered set so it can never reveal inaccessible children.
- page.repo.getSpaceDescendants: recursive CTE seeded by space roots.
Client:
- SpaceTree is forwardRef exposing expandAll/collapseAll/isExpanding;
expandAll fetches the whole tree once, replaces current-space nodes, opens
every branch (current space only), aborts on space switch, surfaces real
errors; collapseAll collapses only current-space ids (shared open-map).
- SpaceMenu gains Expand all / Collapse all items (no admin gate).
Implements docs/backlog/tree-expand-collapse-all.md.

Replace the implicit `hostname endsWith openrouter.ai` detection with an
explicit, admin-chosen provider field `sttApiStyle` ('multipart' = OpenAI-
compatible multipart /audio/transcriptions; 'json' = OpenRouter-style JSON +
base64 input_audio). The transcription path now branches on the stored field,
not on the URL — nothing hidden from the admin.
- ai.types: add SttApiStyle + STT_API_STYLES; field on AiProviderSettings and
MaskedAiSettings (resolved via ResolvedAiConfig).
- update-ai-settings.dto: validate sttApiStyle with @IsIn(STT_API_STYLES).
- ai-settings.service: plumb sttApiStyle through resolve()/getMasked() and the
non-secret update whitelist; workspace.repo: add it to the ALLOWED array so it
persists.
- ai.service: drop isOpenRouter(); transcribe() branches on cfg.sttApiStyle;
rename helper to transcribeJsonBase64 with provider-neutral error text and a
BadRequestException (400) when the base URL is missing for the JSON style.
- client: SttApiStyle type on IAiSettings/IAiSettingsUpdate; "Request format"
Select on the Voice/STT settings card; i18n.
Add push-to-talk voice dictation that transcribes recorded audio on the
server via the workspace's OpenAI-compatible AI provider (Whisper /
gpt-4o-transcribe / self-hosted whisper), then inserts the text.
Backend:
- New `stt_api_key_enc` column + migration; STT creds parity with chat/
embeddings (sttModel/sttBaseUrl/sttApiKey, write-only key, fallbacks to
chat baseUrl/key). Both provider whitelists updated (service + repo).
- AiService.getTranscriptionModel + AiTranscriptionService.
- Gated POST /ai-chat/transcribe (dictation flag → 403, JWT + workspace
scope + throttle, 25MB cap, MIME whitelist, never logs audio/key).
- New `settings.ai.dictation` workspace flag (DTO + service + audit).
Frontend:
- Wire up the Voice/STT settings card (model/base URL/key) and the
Voice-dictation toggle.
- New `features/dictation`: useDictation (MediaRecorder state machine),
MicButton, transcribe service; integrated into the chat composer and a
new editor-toolbar dictation group, both gated by ai.dictation.
Improve agent RAG quality with three changes, plus a roadmap doc for the rest.
- Indexer: prefix each chunk with its heading path ("Page > H1 > H2"), built by
walking the ProseMirror JSON (heading nodes) so a `#` inside a fenced code block
is never mistaken for a heading. Falls back to plain-text chunking on any error.
buildChunkRows: drop indexOf-against-source offsets (breadcrumb prefixes break
verbatim matching) for a cumulative cursor — offsets are provenance-only.
- Hybrid search: new migration adds a generated `fts` tsvector column + GIN index
to page_embeddings (same english+f_unaccent config as pages.tsv). New
PageEmbeddingRepo.hybridSearch fuses cosine + full-text rankings via Reciprocal
Rank Fusion (k=60, equal weights) in one SQL query at chunk granularity.
- Tools: collapse semanticSearch + searchPages into one hybrid `searchPages` tool
with a query-rewrite-oriented description; gracefully falls back to the REST
full-text path when embeddings are unconfigured. Access control (space scope +
page-permission post-filter) preserved. Add a query-rewrite hint to the default
system prompt.
- docs/rag-improvements-plan.md: record what shipped and the deferred backlog
(reranker, attachment indexing, eval harness, tuning).
Note: requires a corpus reindex to populate breadcrumbs on existing pages.
"Indexed N of M pages" stayed at e.g. "27 of 34" forever even after a
successful full reindex. The numerator counted pages that have embeddings
while the denominator counted ALL non-deleted pages, so empty / text-less
pages (which legitimately store zero embeddings) could never be reached.
Add PageRepo.countEmbeddablePages: counts non-deleted pages that have
non-empty textContent OR already have a stored embedding row, and use it as
the totalPages denominator in AiSettingsService.getMasked. The "has
embeddings" clause covers pages indexed from the content JSON (null
textContent) and guarantees indexedPages <= totalPages. No DB migration.
The WORKSPACE_CREATE_EMBEDDINGS / WORKSPACE_DELETE_EMBEDDINGS jobs were
enqueued (on AI Search enable/disable) but had no AI_QUEUE handler, so
existing pages were never indexed ("Indexed 0 of N pages") and disabling
never purged embeddings.
- EmbeddingProcessor: handle WORKSPACE_CREATE_EMBEDDINGS (bulk reindex all
live pages) and WORKSPACE_DELETE_EMBEDDINGS (purge workspace embeddings)
- EmbeddingIndexerService: add reindexWorkspace() (skips when embeddings
unconfigured; per-page error isolation) and removeWorkspace()
- PageRepo.getIdsByWorkspace(), PageEmbeddingRepo.deleteByWorkspace()
- AiSettingsService.reindex() + admin-only POST /workspace/ai-settings/reindex
- Frontend: "Reindex now" button, service call and mutation
- Stable per-workspace jobId with remove-before-add so a stale job can't
block future reindexes; cancel the delayed purge on enable/reindex so it
can't wipe freshly-built embeddings
Per-workspace AI provider config previously shared a single base URL and
a single API key between the chat model and the embedding model. Add
dedicated, optional embedding endpoint/token that fall back to the chat
values when empty, preserving backward compatibility.
- db: new migration adds nullable `embedding_api_key_enc` to
`ai_provider_credentials`; chat key stays in `api_key_enc`
- repo: add `upsertEmbeddingKey` / `clearEmbeddingKey` (on-conflict
touches only its own column, so chat/embedding keys never overwrite)
- ai-settings.service: store non-secret `embeddingBaseUrl`; resolve()
applies fallback (embeddingBaseUrl || baseUrl; embedding key || chat
key); getMasked() exposes raw `embeddingBaseUrl` + `hasEmbeddingApiKey`,
never the key; update() handles the embedding key write-only
- ai.service: getEmbeddingModel() builds openai/gemini/ollama with the
embedding-specific URL/key; chat path unchanged
- client: new "Embedding base URL" and "Embedding API key" fields with
fallback hints and a clear-key action
Requires running the DB migration on deploy.
Display "Indexed N of M pages" on the AI provider settings page so admins
can see how much of the wiki is covered by vector-RAG semantic search.
- page-embedding.repo: add countIndexedPages() — distinct non-deleted pages
that have stored embeddings in the workspace
- page.repo: add countByWorkspace() — total non-deleted pages
- ai-settings.service: compute both counts in getMasked() (Promise.all) and
return them with the masked settings; inject PageEmbeddingRepo + PageRepo
- MaskedAiSettings / IAiSettings: add indexedPages + totalPages
- ai-provider-settings: render a dimmed coverage line under "Embedding model"
- i18n: add the "Indexed {{indexed}} of {{total}} pages" key (en-US, ru-RU)
Page-history snapshots are debounced/coalesced (one per 1–5 min window,
jobId=page.id). A human edit followed by an agent edit in the same window
collapsed into a single snapshot, losing both the pre-agent human state and
a deterministic record of the agent's result.
Two provenance-aware boundaries now bracket an agent intervention:
- Before: on a user->agent transition, onStoreDocument synchronously pins the
current (pre-agent) human content as its own history version tagged 'user',
inside the page-write transaction, before the agent overwrites it.
- After: agent stores enqueue an immediate (delay 0), source-keyed history job
(jobId=`${pageId}:agent`) so the agent's result snapshots deterministically
as 'agent' and a later human edit (jobId=page.id) cannot coalesce/retag it.
Also add an `id desc` tie-break to findPageLastHistory so "last history" stays
deterministic when two snapshots share a created_at, consistent with
findPageHistoryByPageId.
Known trade-offs (Variant 1): the delay-0 worker re-reads the row, leaving a
millisecond mis-tag window; multiple agent edits in one turn may yield multiple
versions. The reverse agent->human boundary is intentionally out of scope.
