📄 fix: Serve Stored Text for "Upload as Text" File Downloads (#14723)
* 📄 fix: Serve Stored Text for Text-Source File Downloads

"Upload as Text" attachments store extracted content in the DB with
source 'text'; OCR uploads persist the OCR strategy name (e.g.
'mistral_ocr') as a filepath placeholder since no backing file exists.
The download route resolved these records to the local strategy and
passed the placeholder to fs.createReadStream, which failed with
ENOENT — and the response was never ended after the stream error, so
the request hung until the client timed out.

Serve the stored text directly as a .txt download for text-source
files (re-fetched by _id, as getFiles excludes 'text' by default),
and end the response on stream errors: 500 without the download
headers before headers are sent, otherwise abort the truncated
response so clients detect the failure.

* fix: Preserve text-source preview semantics

🔗 feat: Shared Conversation Badge and Stable Share Links (#14712)
* feat: improve shared conversation links

* test: Cover Shared Link Lifecycle

* test: Cover Shared File Snapshots

* fix: address review findings on shared links

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.

* 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.

🔄 feat: Continue Shared Conversations as Personal Copies (#13714)
Adds a "Continue this chat" button to the shared conversation view that forks
the shared conversation into a new conversation owned by the viewer and opens it
to continue (issue #13001).

- POST /api/share/:shareId/fork, gated by requireJwtAuth, the fork rate
  limiters, and the canAccessSharedLink ACL (view access = fork access).
- forkSharedConversation clones from the anonymized getSharedMessages payload,
  so only share-visible data is copied.
- Strips file ids from cloned files/attachments so a fork grants no more file
  access than viewing the read-only share, and honors the global shared-file
  kill switch via the snapshotFiles option.
- Reduces the clone to the viewer's active branch, located by its index in the
  shared payload (shared ids are re-anonymized per request and createdAt can
  collide, while the payload order is stable).
- Resolves config/retention, persists, and reads back under the requesting
  user's tenant, not the share owner's; canAccessSharedLink also falls back to
  a system-wide share lookup so cross-tenant public shares resolve (ACL still
  enforced under the share's own tenant).
- Resolves a usable endpoint/model from the viewer's models config instead of
  hard-coding OpenAI, so deployments without OpenAI can send the first message.
- Routes the fork's 401s (logged-out or cold-loaded viewers) through login,
  including when the refresh itself is rejected for a stale session.
- Hides the Temporary Chat toggle once a conversation has a real id, and
  portals the share-settings theme/language dropdowns above the dialog.

Rebased onto dev; collapses the share-fork feature and its review fixes into a
single commit.

* 🔗 feat: Snapshot Files for Shared-Link Attachments

Shared-link viewers could read a shared conversation snapshot but not its
attachments: file preview/download still went through the owner-scoped file
ACL (the /api/files router sits behind requireJwtAuth + owner/agent checks),
so anonymous viewers got 401s and authenticated non-owners got 403s — the
repeated `[fileAccess] denied` warnings seen for the preview poller.

Capture an immutable per-share file snapshot (embedded on the SharedLink
document, referencing the original stored object — no byte copy) at share
create/update, and serve those files through new share-scoped routes
authorized by the existing shared-link view permission (public/ACL) plus
snapshot membership, never the owner's live file ACL.

- data-schemas: fileSnapshots on the share doc; capture in create/update;
  read-time rewrite of filepath/preview to /api/share/:id/files/:fileId;
  getSharedLinkFile + lazy backfillSharedLinkFiles for legacy links
- api: GET /api/share/:shareId/files/:file_id[/download|/preview]; route
  context added to fileAccess denial logs
- packages/api: isFileSnapshotEnabled resolver (env + yaml)
- data-provider: interface.sharedLinks.snapshotFiles (default on) + client
  endpoints/services
- client: ShareContext.shareId wired to Image, preview hook, and downloads
- config: SHARED_LINKS_SNAPSHOT_FILES env override (default on)

* 🔒 fix: Address Codex review on shared-link file snapshots

Triage of the Codex review on PR #13740 (2 P1, 7 P2 — all valid):

- P1 (cross-user access): scope the snapshot lookup to the sharing user's own
  files so a message referencing another user's file_id can't widen access.
- P1 (stored XSS): the inline share-file route now serves only safe preview
  types inline (raster images/pdf); everything else is forced to attachment with
  X-Content-Type-Options: nosniff.
- Stream shared downloads by default; redirect to a signed URL only on
  ?direct=true (blob/XHR callers work without bucket CORS).
- Read preview status live from the file record (always current for deferred
  previews) and stop embedding extracted text in the share doc (16MB-limit risk).
- Only lazily backfill when the fileSnapshots field is absent (legacy), not on
  every snapshot miss.
- Backfill legacy shares before rewriting message URLs, and gate URL rewriting
  to public shares so non-public (ACL) shares keep prior behavior (img/anchor
  can't carry the bearer token).
- Frontend: only route a download through the share path when the file was
  actually snapshotted (rewritten href / filepath), else fall back.

* 🔑 feat: Authorize shared-link files for non-public shares via cookie

Extends shared-link file access to non-public (ACL) shares (Codex finding 5).
`<img>`/anchor requests can't carry the bearer access token, so non-public
shares previously 401'd on file loads. Add an optional cookie-auth fallback on
the share file routes that resolves the viewer from the `refreshToken` cookie
(or signed `openid_user_id` cookie) — the same mechanism secure image links use
(validateImageRequest) — then let canAccessSharedLink run the viewer's ACL check.

- new middleware optionalShareFileAuth (+ unit spec); applied to the three
  share file routes after optionalJwtAuth
- URL rewriting in getSharedMessages is no longer gated to public shares (the
  route now authorizes header-less requests), so files work uniformly across
  public and non-public shares; revert the now-unused req.sharePublic plumbing

* 🔒 fix: Second Codex pass on shared-link file snapshots

Addresses the follow-up Codex findings on PR #13740:

- Don't snapshot transient text-source files: FileSources.text filepaths are
  Multer temp paths the upload route deletes, so they can't be streamed —
  removed from the streamable allowlist.
- Unset stale snapshots on a disabled-feature update: updateSharedLink now
  $unsets fileSnapshots when snapshotFiles is false, so an opted-out update
  can't keep serving file ids the update dropped.
- Load tenant config after share resolution: configMiddleware now runs after
  canAccessSharedLink (which enters the share's tenant ALS context), so
  per-tenant interface.sharedLinks.snapshotFiles overrides apply to anonymous
  public views.
- Return a clean 404 when the snapshotted object is gone: resolveShareFile now
  requires the live file record and 404s if it's been deleted/expired, instead
  of letting the stream error after headers are sent (ENOENT / 500).

(The re-flagged P1 about private-viewer rewriting was already fixed in the prior
commit's cookie-auth change.)

* 🔒 fix: Third Codex pass on shared-link file snapshots

Addresses the third Codex review pass on PR #13740:

- P1: keep shared previews/files pinned to the snapshotted version. Snapshot the
  small previewRevision; resolveShareFile 404s when the live file's revision no
  longer matches (file_id reused/overwritten by a later turn), so old links can't
  surface post-share content — covers both preview text and streamed bytes.
- Honor the toggle as a kill switch: resolveShareFile 404s when snapshotFiles is
  disabled, instead of only skipping backfill, so disabling stops serving
  already-snapshotted file URLs.
- Lazy-sweep orphaned 'pending' previews to 'failed' in the share preview route
  (mirrors the owner route) so the client poller reaches a terminal state.
- Resolve the cookie-fallback user in runAsSystem so strict tenant isolation
  doesn't throw before canAccessSharedLink establishes the share tenant context.

*  feat: Per-link "share files" checkbox for shared links

Add a checkbox to the share-link dialog (checked by default) letting the user
choose whether to include the conversation's files in the shared link, with
copy explaining images/files won't be visible to viewers otherwise. Opting out
skips snapshot creation/serving for that link.

- client: ShareButton renders the checkbox gated on the new
  startupConfig.sharedLinksSnapshotFilesEnabled flag; state threads through
  SharedLinkButton into the create/update mutations as `snapshotFiles`.
- data-provider: createSharedLink/updateSharedLink send `snapshotFiles` in the
  body; TStartupConfig gains `sharedLinksSnapshotFilesEnabled`.
- api: POST/PATCH /api/share compute snapshotFiles as
  isFileSnapshotEnabled(req.config) && body.snapshotFiles !== false (admin gate
  AND per-link opt-out); config.js exposes the effective enabled flag to clients.
- en locale: com_ui_share_files (+ _description).

* 🐛 fix: Make the "share files" opt-out actually hide files

Unchecking "share files" at creation didn't hide anything: the shared message
JSON still carried each file's original (e.g. static-served) path, and because
opting out only meant "no fileSnapshots field" — indistinguishable from a legacy
link — getSharedMessages would backfill snapshots on first view whenever the
admin feature was on, re-enabling files entirely.

Fix by persisting and honoring the per-link choice:
- Store `snapshotFiles` (boolean) on the SharedLink so opt-out is distinct from a
  legacy link; set it on create and update.
- getSharedMessages computes includeFiles = adminEnabled && link not opted out;
  when excluded it strips files/attachments from the payload (no original-path
  leak) and never backfills the opted-out link.
- Surface the stored choice via getSharedLink so the dialog checkbox reflects an
  existing link's actual setting instead of always defaulting to checked.

Note: changing the checkbox on an already-created link still applies only when
the link is refreshed (which regenerates the URL) — a UX follow-up.

* 🔒 fix: Close remaining shared-link file opt-out leaks (Codex)

Follow-up to the per-link opt-out, addressing the third Codex pass:

- Honor the opt-out on the file route too: getSharedLinkFile now returns the
  link's `optedOut` choice; resolveShareFile 404s (and never backfills) an
  opted-out link, so a direct /files/:id request can't re-create snapshots.
- Make read/serve viewer-independent: the gate no longer uses the viewer's
  resolved config (isFileSnapshotEnabled(req.config)) — it uses the link's stored
  choice plus a global env-only kill switch (isFileSnapshotKillSwitchActive). A
  viewer's own interface.sharedLinks.snapshotFiles can no longer hide a link's
  files. Create/update still use the creator's config to set the per-link choice.
- Neutralize render URLs for non-snapshotted files: applyShareFileRoute now
  strips filepath/preview for any file/attachment not in the snapshot, so the
  owner's original (e.g. static) path can't be loaded through the share.

* 🔒 fix: Harden shared-file version pinning and local path handling (Codex)

- Refuse reused/overwritten file snapshots more broadly: resolveShareFile now
  refuses to serve when either previewRevision OR `bytes` changed vs the
  snapshot. `bytes` catches non-office reused outputs (e.g. code-exec
  same-filename images that lack previewRevision) and is stable across S3 URL
  refresh and the pending->ready transition. Same-size content swaps remain a
  best-effort gap inherent to the no-byte-copy design.
- Strip cache-busting query strings before local streaming: code-output images
  add `?v=...` to filepath; the share route now splits it off so getLocalFileStream
  resolves the real filename instead of a literal `*.png?v=...` path.

* 💬 fix: Clarify that file-sharing changes apply on link refresh

For an already-created shared link, changing the "share files" checkbox only
takes effect when the link is refreshed (which regenerates the snapshot). Add a
note under the checkbox, shown only when a link already exists, so the behavior
isn't surprising: "Refresh the link to apply this change — files are snapshotted
when the link is refreshed."

🔗 feat: Add Granular Access Control to Shared Links via ACL System (#13051)
* feat: Add granular access control to shared links via ACL system

* fix(shared-links): preserve isPublic on failed migration grants

Transient ACL failures during auto-migration permanently stranded
links — $unset ran unconditionally, removing the legacy flag that
triggers retry. Now only $unset isPublic after all grants succeed.

* fix(config): skip isPublic unset for failed ACL grants

Bulk migration unconditionally removed isPublic from all links,
even those whose ACL writes failed. Failed links then lost the
legacy marker needed for auto-migration retry. Now tracks failed
link IDs per-batch and excludes them from the $unset step.

Also adds sharedLink to AccessRole resourceType schema enum —
was missing, only worked because seedDefaultRoles uses
findOneAndUpdate which bypasses validation.

* ci(config): add jest config and PR workflow for migration tests

config/__tests__/ specs depend on api/jest.config.js module
mappings but had no dedicated runner. Adds config/jest.config.js
extending api config with absolutized paths, npm test:config
script, and a GitHub Actions workflow triggered by changes to
config/, api/models/, api/db/, or packages/ ACL code.

* fix(permissions): honor boolean sharedLinks config

SHARED_LINKS has no USE permission, so boolean config produced
an empty update payload — gate conditions only matched object
form, making `sharedLinks: false` a no-op on existing perms.

* fix(share): resolve role before creating shared link

Role lookup between create and grant left an orphaned link
without ACL entries if getRoleByName threw — retry then hit "Share already exists" with no recovery path.

* fix: Restore Public ACL Access Checks

* fix: Type Public ACL Lookup

* fix: Preserve Private Legacy Shared Links

* chore: Promote Shared Link Permission Migration

* fix: Address Shared Link Review Findings

* fix: Repair Shared Link CI Follow-Up

* feat: support data retention for normal chats

Add retentionMode config variable supporting "all" and "temporary" values.
When "all" is set, data retention applies to all chats, not just temporary ones.
Adds isTemporary field to conversations for proper filtering.

Adapted to new TS method files in packages/data-schemas since upstream
moved models out of api/models/.

Based on danny-avila/LibreChat#10532

(cherry picked from commit 30109e90b0)

* feat: extend data retention to files, tool calls, and shared links

Add expiredAt field and TTL indexes to file, toolCall, and share schemas.
Set expiredAt on tool calls, shared links, and file uploads when
retentionMode is "all" or chat is temporary.

* fix: lint/test

(cherry picked from commit 310c514e6a)

* fix: address code review feedback for data retention PR

Critical:
- Fix BookmarkMenu crash: restore optional chaining on conversation
- Fix migration hazard: backward-compatible sidebar filter that also
  checks expiredAt for documents without isTemporary field

Major:
- Add logging to getRetentionExpiry error path, align with tools.js
- Add tests for retentionMode: ALL in saveConvo and saveMessage
- Fix share route: apply expiredAt for temporary chats too by
  querying the conversation's isTemporary flag server-side
- Add assertions for getRetentionExpiry mocks in process tests

Minor:
- Fix ChatRoute isTemporaryChat to be strictly boolean via Boolean()
- Fix stale test description (expired -> temporary)
- Comment out retentionMode default in example yaml
- Simplify verbose if/else to isTemporary === true
- Add compound index on { user: 1, isTemporary: 1 }
- Remove narrating comment from process.spec.js

* fix: use mockSanitizeArtifactPath in retention test

The 'getRetentionExpiry is called with the request object' test
referenced an undefined `mockSanitizeFilename` identifier, breaking
both lint (no-undef) and the test suite. Use the existing
`mockSanitizeArtifactPath` mock that the surrounding tests already
use, since `processCodeOutput` calls `sanitizeArtifactPath` (not
`sanitizeFilename`) before invoking `getRetentionExpiry`.

* fix: forward isTemporary from client for retention on file uploads and tool calls

Server-side `getRetentionExpiry` (file uploads) and the tool-call
controller both read `req.body.isTemporary`, but the file upload
multipart form and the tool-call payload did not include that field.
In `retentionMode: temporary` (default), files uploaded and tool
calls created from temporary chats were therefore retained
indefinitely.

Forward the Recoil `isTemporary` flag in both client paths so the
existing server checks can fire correctly. `ToolParams` gains an
optional `isTemporary` field.

Addresses Codex P1 review feedback on PR #29.

* test: stub store.isTemporary in useFileHandling test mocks

Previous commit added `useRecoilValue(store.isTemporary)` to the
hook. The test file mocks `~/store` with only `ephemeralAgentByConvoId`
and does not stub `useRecoilValue`, so all 7 cases threw
"Invalid argument to useRecoilValue: expected an atom or selector but
got undefined". Add a stub default export with `isTemporary` and a
`useRecoilValue` mock returning `false`.
