Summary

Closes #8318.

Today nothing in the UI tells you a conversation has a live public share link. You have to open the share dialog per conversation to find out. This PR surfaces that state in the chat list and the header, and while working through the share flow it fixes a set of correctness and disclosure bugs in the shared-link backend.

Making an active share visible (#8318)

isShared is derived per request from the shared-links collection in one batched lookup (attachSharedFlags), covering both the cursor and legacy pagination paths. It is deliberately not persisted on the conversation, and a failure there logs and drops the badge rather than failing the conversation list. Sidebar rows render a Link2 icon with a distinct aria-label ("... conversation, shared link active"), so the state is not conveyed by icon alone, and the header Export/Share button gets a matching dot indicator. The share mutations flip the flag in cache so the badge does not lag a conversation-list refetch.

A share link that keeps its URL

Updating a link previously minted a new shareId, silently breaking every URL already handed out. PATCH now preserves the shareId, so the action republishes the latest messages and the current file-sharing choice to the same URL. It is renamed from "Refresh link" to "Update link", gains a confirmation step, and the copy now describes the snapshot semantics instead of implying the URL rotates. The dialog action row becomes icon-only (manage access, update, QR, delete) with native share on small screens, and the URL field is extracted into SharedLinkCopyButton.

Backend correctness and disclosure fixes

  • getMessagesUpToTarget fails closed when the target message is missing. It previously returned the entire conversation, widening a branch-scoped share to everything.
  • Create and update reject an unknown targetMessageId (400) rather than silently re-scoping the share.
  • Anonymization maps are per response instead of process-global. The global maps let a viewer correlate the same conversation or assistant across distinct links, and grew without bound.
  • PATCH /:shareId is gated on the same CREATE permission as POST, since it republishes content. DELETE stays ungated so an owner can always retract a link they may no longer create.
  • GET /share validates its query params: page size clamped to 1-100, cursor checked as a date, search length capped, and the 500 response no longer echoes error.message.
  • Two concurrent creates could both clear the existence check. Racers now evaluate the same total order (createdAt, then _id), the loser retracts its own document and returns 409.
  • Shared-file streaming awaits completion and removes its listeners, and destroys the response when headers were already sent instead of leaving a half-written body.
  • A 403 on shared-link access no longer returns a message body.

Supporting changes

Shared Links and Archived Chats move onto the newer DataTable (with getRowId); the previous export is preserved as LegacyDataTable so existing consumers are unaffected. Bulk delete gets its own success and partial-failure messaging, InfoHoverCard gains an icon variant and a real button trigger for keyboard access, and a surface-qr theme token is added (an always-white backdrop so QR codes stay scannable in dark mode). The header indicator reuses the existing status-info token rather than introducing a colour.

Change Type

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Translation update

Testing

Unit and integration suites were run per workspace against this branch, and ESLint was run across every changed file.

cd api && npx jest server/routes/__tests__/share.spec.js
cd packages/data-schemas && npx jest src/methods/share.test.ts src/methods/conversation.spec.ts
cd client && npx jest src/components/Conversations/__tests__/sharedBadge.test.ts \

cd packages/client && npx jest src/components/DataTable
cd packages/data-provider && npx jest specs/api-endpoints.spec.ts
cd packages/api && npx jest src/shared-links/access.test.ts
Workspace Suite Result
api share.spec.js 47 passed
packages/data-schemas share.test.ts, conversation.spec.ts 139 passed
client shared badge, ExportAndShareMenu, ShareButton, SharedLinkButton, share mutations 22 passed
packages/client DataTable suites 115 passed
packages/data-provider api-endpoints.spec.ts 12 passed
packages/api shared-links/access.test.ts 17 passed

New coverage added by this PR includes the shared-link lifecycle (create, update preserving shareId, delete, the concurrent-create race, and the fail-closed target-message behaviour), the shared file snapshot paths, the sidebar badge, and the share mutation cache updates.

The Playwright spec e2e/specs/mock/shared-links.spec.ts is updated in this PR but requires a running app, so it is not part of the run above.

Test Configuration:

Node.js v24.16.0, MongoDB via mongodb-memory-server for the backend suites, Jest per workspace.

Stop double-decoding the conversation search term. Express already decodes
req.query, so the route's extra decodeURIComponent threw URIError on any term
containing a bare percent sign and mangled percent-escape-looking text. The
sidebar already sent the term raw, so this failed there too.

Advance a share's stored target to its branch tail when an update omits one.
Updating from the conversation list could not resolve the tail and reused the
stored target verbatim, silently republishing the same snapshot instead of the
turns added since.

Require revalidation on shared files. Updates now keep the shareId, so the file
URL no longer changes and a cached response could outlive a revoked share-files
choice; an ETag over the pinned snapshot fields keeps unchanged files on 304.

isShared is derived per list request and absent from single-conversation
payloads, so rename, pin, and the SSE conversation updates dropped it when they
swapped a server response into the sidebar cache, hiding the badge until an
unrelated list refetch. Carry the cached value forward in updateConvoInAllQueries
so every replacing caller is covered, while an explicit value still wins.
initializeMCPs now calls syncStaticTools when no MCP servers are configured, but the server boot specs stub ~/server/services/Config without it. Post-listen initialization threw, hit process.exit(1), and took the jest worker down until it exceeded the retry limit.

Keep the published DataTable export bound to the legacy component and ship the design-system table as VirtualizedDataTable, so external consumers of @librechat/client keep the props they compile against.

Fold the snapshot's stored location into the shared-file ETag, so a re-published output that keeps its size and revision but moves its object no longer revalidates to a stale 304.

Auto-fill the table when a first page is too short to overflow its container, since pagination is otherwise only reachable through the scroll handler.

Move the shared-link ACL expiration write ahead of the content update. The shareId survives an update, so a failed ACL write after the write-through left the new messages and file snapshot readable at the same URL while the owner saw a 500.

Retry a rejected auto-fill fetch up to three times: an unscrollable table has no scroll event to fall back on, and the sentinel alone would strand it on the first page.

advanceTargetToBranchTail only walked descendants, so a target replaced by a regeneration (a sibling, not a child) left the update parked on the obsolete branch and published none of the turns that followed. A childless target now hops once to the newest sibling the conversation continued under.

A shareId survives an update, so an owner republishing between a viewer's load and their Continue click would resolve targetMessageIndex against different messages. The fork request now carries the payload's updatedAt and is rejected with 409 when it no longer matches; the viewer gets the current version pulled in and can retry.

Restore the union formatting a local lint-staged prettier collapsed in data-provider types, which broke the CI lint run.

Header clicks now toggle direction instead of cycling through an unsorted state, which the controlled tables translated straight back into the default and made one direction unreachable.

Re-arm the auto-fill guard on a sort change: a re-sorted first page arrives with the same row count, and the guard would otherwise suppress paging on a container that still cannot scroll.

Lazy fileSnapshots backfills no longer touch updatedAt. That timestamp is the revision a viewer's fork is validated against, so a legacy share's first read would have made the Continue click that followed it fail with a 409.

Cursor validation, page-size clamping and the shared-file cache validator were plain backend logic sitting in the legacy JS route. They now live in packages/api with their own tests, and the route keeps only the Express-side wiring: reading query params, mapping domain error codes to status codes, and writing the response.

Also carries the requested file choice into the cache entry the create and update mutations synthesize, since the response never echoes it and the dialog reads a resolved entry with no choice as the enabled default.

A search or sort swap keeps the previous rows and hasNextPage on screen while the new first page loads, so the re-armed auto-fill asked for page two against a query that was still fetching its first. An infinite query runs one fetch at a time, so that request could cancel or interfere with the one already out. Both tables now pass their fetching state and the guard waits for it.

The sidebar badge rendered from the derived flag alone, so a deployment that turned shared links off still told owners a link was live while the public routes were unregistered.

The share dialog called the link a snapshot, but the payload populates the referenced message documents on every request: an edit to an already-shared message is visible immediately, and Update only adds newly referenced ones. The copy now says that.

Scroll pagination inspects a resolved error the way auto-fill already does, since React Query reports a failed page that way instead of rejecting.

The cursor cap was tight enough that a Name-sorted page ending on a long title produced a nextCursor the next request rejected, stranding the rest of the list. It now sits well clear of anything the server can issue.

The conversation list skipped straight into the shared-link lookup even where ALLOW_SHARED_LINKS is off, paying a round trip on the sidebar's first page for a badge that is never rendered.

A regeneration is newer than what it replaced, so only a newer sibling counts: an older one that still has follow-ups is the branch the target was regenerated away from, and resuming there published turns the target had excluded.

Resetting the viewport to the top after a search or sort change fires a scroll event, and the retained previous rows still report another page, so the handler asked for page two of a query that was still loading page one.

A legacy row keeps its marker until every grant it needs exists, so an owner grant on its own is not proof the migration finished. Reading the marker first means a half-migrated public link still gets its public grant, while a fully migrated one keeps the read-only settled path the badge lookup depends on.

URL no longer changes and a cached response could outlive a revoked share-files
choice; an ETag over the pinned snapshot fields keeps unchanged files on 304.

* fix: keep the shared badge across conversation cache replacements

isShared is derived per list request and absent from single-conversation
payloads, so rename, pin, and the SSE conversation updates dropped it when they
swapped a server response into the sidebar cache, hiding the badge until an
unrelated list refetch. Carry the cached value forward in updateConvoInAllQueries
so every replacing caller is covered, while an explicit value still wins.

* test: mock syncStaticTools in server boot specs

initializeMCPs now calls syncStaticTools when no MCP servers are configured, but the server boot specs stub ~/server/services/Config without it. Post-listen initialization threw, hit process.exit(1), and took the jest worker down until it exceeded the retry limit.

* fix: address codex findings on the shared DataTable and file ETag

Keep the published DataTable export bound to the legacy component and ship the design-system table as VirtualizedDataTable, so external consumers of @librechat/client keep the props they compile against.

Fold the snapshot's stored location into the shared-file ETag, so a re-published output that keeps its size and revision but moves its object no longer revalidates to a stale 304.

Auto-fill the table when a first page is too short to overflow its container, since pagination is otherwise only reachable through the scroll handler.

* fix: re-scope share grants before publishing and retry stalled auto-fill

Move the shared-link ACL expiration write ahead of the content update. The shareId survives an update, so a failed ACL write after the write-through left the new messages and file snapshot readable at the same URL while the owner saw a 500.

Retry a rejected auto-fill fetch up to three times: an unscrollable table has no scroll event to fall back on, and the sentinel alone would strand it on the first page.

* fix: follow regenerated branches and pin forks to the payload they saw

advanceTargetToBranchTail only walked descendants, so a target replaced by a regeneration (a sibling, not a child) left the update parked on the obsolete branch and published none of the turns that followed. A childless target now hops once to the newest sibling the conversation continued under.

A shareId survives an update, so an owner republishing between a viewer's load and their Continue click would resolve targetMessageIndex against different messages. The fork request now carries the payload's updatedAt and is rejected with 409 when it no longer matches; the viewer gets the current version pulled in and can retry.

* fix: keep table sorting and legacy backfills from breaking share flows

Restore the union formatting a local lint-staged prettier collapsed in data-provider types, which broke the CI lint run.

Header clicks now toggle direction instead of cycling through an unsorted state, which the controlled tables translated straight back into the default and made one direction unreachable.

Re-arm the auto-fill guard on a sort change: a re-sorted first page arrives with the same row count, and the guard would otherwise suppress paging on a container that still cannot scroll.

Lazy fileSnapshots backfills no longer touch updatedAt. That timestamp is the revision a viewer's fork is validated against, so a legacy share's first read would have made the Continue click that followed it fail with a 409.

* fix: break pagination ties by id and reset share state per conversation

Both list cursors marked a page boundary with values that repeat: conversations by (sort field, updatedAt) and shared links by the sort field alone. Imported chats share a title and a timestamp, so every row tied with the boundary was skipped. Both now carry the boundary row's _id and sort by it last, and the shared-links cursor is an opaque composite the route still validates before querying.

The share dialog outlives a switch between conversations, so a link with files disabled left the next conversation's dialog showing the switch off and quietly published without files. The stored choice now falls back to the enabled default, and a stale link no longer sits in the copy field.

* fix: keep titleless shared links in the paginated list

A share has no title default, and BSON orders a missing title before every string, so encoding the boundary as an empty string skipped the remaining untitled links when sorting Name ascending and re-admitted all of them descending.

The cursor now carries the boundary's null rather than flattening it, and because $lt and $gt are type-bracketed against a string, descending adds an explicit clause for the untitled tail that a string comparison can never reach.

* style: sort share method imports

* fix: fail closed on orphaned share targets and guard snapshot backfills

getMessagesUpToTarget walked levels from the roots and returned everything it had accumulated when the target was never reached. An imported or partially deleted branch whose parent is missing therefore published the whole conversation instead of the selected branch; the walk now returns nothing unless it actually reaches the target.

A lazy backfill wrote fileSnapshots unconditionally, so a viewer's first read of a legacy link could land after a republish and restore the snapshot it replaced, re-authorizing the stable URL of a file the owner had just removed. The write is now conditional on the link still having no snapshot, and the stored one wins any race.

Regenerating a message above the shared tail leaves the whole stored branch childless, so the target walk now climbs to the closest ancestor the conversation continued under instead of stopping at the stored tail's own siblings.

Changing the search or sort also returns the table's viewport to the top, since the query holds the previous rows while it refetches.

* fix: page through titleless rows on both sides of the cursor

The route validator still required a string primary, so the composite cursor the data layer issues for a titleless boundary came back as a 400 and the shared-links table stopped at that page.

Conversations had the same type-bracketing gap the shared links just closed: a name-sorted page could not reach conversations with no title, since a comparison against a string never matches a missing field. The cursor now carries the null and the filter spells out the titleless clauses for both directions.

* fix: keep the share badge read-only and refresh rows on cell changes

ensureLinkPermissions re-granted the owner ACL entry on every call, so rendering the header's shared badge turned ordinary navigation into a permission write. It now checks for the grant first and only migrates a link that still lacks one.

A fork carrying a positional target but no revision falls back to the whole share, since nothing proves which payload the index was counted against.

The memoized table row compared row data and selection only, so a cell rendering external state (the archived list's pending Restore, for one) kept its stale rendering until the row object itself moved; rows now also compare a marker that moves with the column definitions.

* fix: keep the shared badge honest when a delete fails or a link remains

A failed delete left the conversation looking unshared: the optimistic snapshot covered only the shared-link queries, not the conversation caches the badge reads. The cleared conversations are now restored with the rest.

A conversation can hold one link per target message, so clearing the badge on delete is a guess. The conversation list is invalidated once the mutation settles, letting the server decide from the links that are actually left.

* fix: refetch every cached conversation page after deleting a link

The invalidation was pinned to page zero, so a conversation cached further down the sidebar kept the badge the optimistic update had already cleared even when another targeted link survived.

* fix: treat a failed page fetch as a failed auto-fill

React Query resolves fetchNextPage with an error result instead of rejecting, so the rejection handler never ran: the guard stayed armed on the unchanged row count and an unscrollable table could never reach the next page.

* refactor: move the share request helpers into the typed backend

Cursor validation, page-size clamping and the shared-file cache validator were plain backend logic sitting in the legacy JS route. They now live in packages/api with their own tests, and the route keeps only the Express-side wiring: reading query params, mapping domain error codes to status codes, and writing the response.

Also carries the requested file choice into the cache entry the create and update mutations synthesize, since the response never echoes it and the dialog reads a resolved entry with no choice as the enabled default.

* fix: hold auto-fill while the replacement page is in flight

A search or sort swap keeps the previous rows and hasNextPage on screen while the new first page loads, so the re-armed auto-fill asked for page two against a query that was still fetching its first. An infinite query runs one fetch at a time, so that request could cancel or interfere with the one already out. Both tables now pass their fetching state and the guard waits for it.

* fix: stop advertising links a deployment no longer serves

The sidebar badge rendered from the derived flag alone, so a deployment that turned shared links off still told owners a link was live while the public routes were unregistered.

The share dialog called the link a snapshot, but the payload populates the referenced message documents on every request: an edit to an already-shared message is visible immediately, and Update only adds newly referenced ones. The copy now says that.

Scroll pagination inspects a resolved error the way auto-fill already does, since React Query reports a failed page that way instead of rejecting.

* a11y: gate the shared conversation label on the feature flag

The icon stopped rendering when a deployment turns shared links off, but the row still announced the conversation as shared to screen readers. Both now read the same condition.

* fix: accept long title cursors and stop badge work the feature disables

The cursor cap was tight enough that a Name-sorted page ending on a long title produced a nextCursor the next request rejected, stranding the rest of the list. It now sits well clear of anything the server can issue.

The conversation list skipped straight into the shared-link lookup even where ALLOW_SHARED_LINKS is off, paying a round trip on the sidebar's first page for a badge that is never rendered.

A regeneration is newer than what it replaced, so only a newer sibling counts: an older one that still has follow-ups is the branch the target was regenerated away from, and resuming there published turns the target had excluded.

* fix: hold scroll pagination while a replacement page loads

Resetting the viewport to the top after a search or sort change fires a scroll event, and the retained previous rows still report another page, so the handler asked for page two of a query that was still loading page one.

* fix: keep the legacy share migration ahead of the owner-grant shortcut

A legacy row keeps its marker until every grant it needs exists, so an owner grant on its own is not proof the migration finished. Reading the marker first means a half-migrated public link still gets its public grant, while a fully migrated one keeps the read-only settled path the badge lookup depends on.
