SECURITY. В публичном share-чате сырой текст ошибки тула или провайдера утекал
анонимному читателю. Три слоя, все обязательны:
(1) Рендер-гейт: prop showErrors в ToolCallCard (протянут через MessageList/
MessageItem), share-виджет передаёт false — сырой errorText не рисуется. Но
рендер-гейт маскирует только DOM, не байты.
(2) Санитизация на уровне share-тулсета (авторитетно): forShare оборачивает
execute каждого тула catch'ем. Своя ShareToolError (безопасные строки: «page not
available in this share») пробрасывается, ЛЮБАЯ другая ошибка → generic «tool
could not complete», полный текст только в серверный лог. Одно место закрывает
байты (атомарный tool-output-error фрейм v6), рендер и контекст модели; self-
correction сохранена.
(3) Анонимный onError пайпа: ShareToolError → её безопасное сообщение; иначе
describeProviderError (statusCode + тело: внутренний baseUrl/модель) только в лог,
читателю — фиксированная классифицированная строка (rate-limited/unavailable/
provider error).
Тест: интеграционный с РЕАЛЬНЫМ падением тула и провайдера — assert по СЫРЫМ SSE-
БАЙТАМ (не по DOM): секрет/baseUrl/стек отсутствуют, видна безопасная строка,
полный текст провайдера ушёл в серверный лог.
For tools without a friendly label (esp. external MCP tools like
Search_web_search) the card showed a generic "Ran tool <name>" with no
sense of what was searched. Add a compact one-line, dimmed summary of the
call's arguments under the label, pulled from part.input.
New pure toolInputSummary(part): picks the first present "primary" field
(query/q/searchQuery/url/urls/title/name/text/prompt), collapses
whitespace, clamps to ~140 chars; arrays render "first (+N)". It returns
undefined during input-streaming (the input grows while state is fixed and
messageSignature doesn't track input, so a live summary would freeze) —
the state flip to input-available re-renders the row with the final value,
so message-signature.ts is left untouched. The value renders ONLY through
Mantine <Text> (React-escaped) — no markdown/HTML, no XSS.
A showInput prop (default true) is threaded MessageList -> MessageItem
(+memo) -> ToolCallCard; the public share widget passes showInput={false}
so an anonymous reader never sees the agent's raw query text (mirrors
showCitations). No JSON fallback when no primary field is present.

The AI chat error banner always showed a generic "Something went wrong"
with no reason. The server already forwards the provider cause into the
stream (e.g. "Cannot connect to API: read ECONNRESET"), but the client
hid it behind a static heading.
- describeChatError now returns { title, detail }: a short heading naming
the cause category plus a one-line explanation.
- Add classifyProviderError: maps connection reset, timeout, rate limit,
context-window overflow, quota and auth failures to clear categories;
the 403/503 gating responses are preserved; unknown errors fall back to
the verbatim provider text.
- Match HTTP status codes only as the leading token and textual signatures
only against the message head (before "| response body:"), so a number
or phrase in the response-body snippet never mislabels the cause.
- Use the new {title, detail} in all three banners: chat-thread,
share-ai-widget and the persisted-error banner in message-item.
- Cover the classifier with 20 unit tests (categories + regressions).
The anonymous public-share "Ask AI" chat labeled every assistant turn
with the generic "AI agent" even when an Assistant identity (agent role)
was configured. Surface the configured identity name instead, falling
back to "AI agent" when no identity is set.
- server: AiSettingsService.resolvePublicShareAssistantName resolves the
configured role's name (null when unset/missing/disabled), mirroring
PublicShareChatService.resolveShareRole; ShareController returns it as
aiAssistantName on /shares/page-info (only when the assistant is on).
- client: thread aiAssistantName -> ShareAiWidget -> MessageList ->
MessageItem/TypingIndicator via an optional assistantName prop; the
internal chat omits it and keeps showing "AI agent".
- i18n: add "{{name}} is typing…" (en-US, ru-RU) for the typing line.

The widget hardcoded a generic 'Something went wrong' body and ignored
error.message, violating AGENTS.md. Render describeChatError(error.message, t) —
the same helper the internal chat uses — so a reader sees the real 402/429/503
cause instead of a bare 'try again'.

The public-share widget was a separate minimal impl: plain-text answer, static
'Thinking…', no markdown, no tool-cards. Now it renders through the internal
chat's debugged presentational layer (MessageList/MessageItem/TypingIndicator/
ToolCallCard), so a share gets the same incremental streaming, animated typing
indicator, markdown, and tool-call cards. The share keeps its anonymous
transport (useChat + DefaultChatTransport '/api/shares/ai/stream',
credentials:'omit').
The shared components were already prop-driven (UIMessage[] + isStreaming) with
no transport/auth coupling; made the new props additive optionals (emptyState,
showCitations, neutralizeInternalLinks) all defaulting to current behavior, so
the internal chat is unchanged.
Security (review-caught): rendering assistant markdown on the ANONYMOUS share
made internal links (/p/{id}, /settings/...) clickable, which the old plain-text
render didn't. renderChatMarkdown gains neutralizeInternalLinks (true only on
the share): a one-shot DOMPurify afterSanitizeAttributes hook (added/removed by
reference around a single sanitize) strips href from internal/relative/non-http(s)
links (rendered inert) and keeps external http(s) links with
rel=noopener noreferrer nofollow target=_blank. Tests cover both the link
neutralization and the absence of any global-hook leak into internal renders.

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).

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.
