Title now lives in the page's Yjs 'title' fragment, but two paths corrupted it:
- Rename-revert: a REST/MCP title change wrote only the page.title column,
never the Yjs fragment, so the next editor open replayed the stale Yjs title
and reverted the rename. PageService.update now mirrors the new title into the
Yjs 'title' fragment via CollaborationGateway.writePageTitle, which goes
through openDirectConnection directly (Redis-independent: works with
COLLAB_DISABLE_REDIS and in single-process deployments, unlike the
Redis-routed handleYjsEvent path). The write is best-effort: a Yjs failure is
logged and never rolls back the committed column write. Agent provenance
(actor/aiChatId) is threaded into the store context.
- Untitled-on-open: an empty/just-initialized 'title' fragment clobbered a
non-empty page.title to '' on open. onStoreDocument now treats the title as
changed only when the extracted text is non-empty, covering both the
title-only and body+title save branches. Empty-retitling via collab is
intentionally impossible; the REST DTO is the place to enforce non-empty.
writeTitleFragment does a full clear+seed of the 'title' fragment (no
duplication/concatenation) and leaves the body fragment intact. Removed the dead
useTreeMutation.handleRename path. Adds unit tests for writeTitleFragment, the
gateway write, the anti-empty-clobber guard, and agent provenance.

Convert the htmlEmbed node from same-origin raw-HTML execution to a sandboxed
iframe (sandbox="allow-scripts allow-popups allow-forms", no allow-same-origin,
srcdoc) with postMessage auto-resize (validated by event.source) and an optional
manual height attr. The block now runs in an opaque origin and cannot reach the
viewer's cookies/session/API, so it is safe for any member.
Because the block is now harmless, remove the entire admin/role gating apparatus:
drop htmlEmbedAllowed/canAuthorHtmlEmbed/stripDisallowedHtmlEmbedNodes/
collectHtmlEmbedSources and every role-based strip on the write paths (collab
REST/MCP + socket, page create/duplicate, import x2, transclusion unsync), along
with the now-unused WorkspaceRepo/UserRepo injections and the PageService.create
callerRole param. Keep one strip: prepareContentForShare still removes htmlEmbed
on the anonymous public-share read path when the workspace master toggle is OFF.
The workspace settings.htmlEmbed toggle is now a plain feature switch (gates the
slash-menu and share rendering); when ON the block is available to all members.
Add settings.trackerHead: an admin-only raw HTML/JS analytics snippet injected
verbatim into the <head> of public share pages only (ShareSeoController), for
trackers that genuinely need same-origin. Admin-gated via the existing CASL
Manage/Settings ability; never injected into the authenticated app shell.
Closes security-review findings #1, #2, #4, #5, #10 (and #3 as a security issue).

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.

Adds an htmlEmbed block node that renders and executes raw HTML/CSS/JS in the
wiki origin (e.g. an analytics tracker) — the owner-chosen variant C. Because
this is stored-XSS by design, only workspace admins/owners may get such a node
persisted; everyone executes it when reading.
- Node (editor-ext): htmlEmbed atom/isolating block; source stored base64 in
data-source for lossless HTML<->JSON round-trip. renderHTML emits only the
encoded marker (never inlines raw markup), so generateHTML/export/search are
not themselves injection vectors. Registered in BOTH client extensions and
server tiptapExtensions. Markdown round-trip via an <!--html-embed:b64-->
comment (turndown) + a marked rule.
- Client NodeView: injects source and re-creates <script> elements so they
actually run; edit modal; renders in read-only/share too. Slash item is
admin-gated (adminOnly filtered by the user's workspace role).
- SERVER ENFORCEMENT (the real control — UI gating alone is insufficient):
stripHtmlEmbedNodes() removes htmlEmbed from any document persisted by a
non-admin, applied at every write path that introduces content from an
untrusted author: collab onStoreDocument, REST/MCP/AI updatePageContent,
single-file import, zip/multi-file import, page duplication, and transclusion
unsync. Page restore introduces no new content. Public share/readonly viewers
render fetched (already-stripped) content and do NOT open a collab socket, so
the only residual is a transient broadcast window to concurrent authenticated
editors (documented).
Implements docs/arbitrary-html-embed-plan.md (variant C).
