f6ee2ea0ee 📜 feat: Skills UI + Initial E2E CRUD / Sharing (#12580)
* 🎨 feat: Skills UI — Create/Edit/Share/List with Conditional File Tree

First-pass UI on top of the CRUD API scaffolding (#12613). Ships the full
user-facing flow for inline, single-SKILL.md skills and leaves a clean
drop-in for phase-2 multi-file support.

- Create a skill from /skills/new with name (kebab-case, validated),
  description, and SKILL.md body — wired to the real `useCreateSkillMutation`
  and `TCreateSkill` payload.
- List skills in a sidebar (SkillsSidePanel) via `useListSkillsQuery` with
  live search filtering.
- Edit any skill the caller has EDIT permission on — `useUpdateSkillMutation`
  passes `expectedVersion` for optimistic concurrency and surfaces 409
  conflicts as a warning toast + cache refetch.
- Non-blocking `TSkillWarning[]` (e.g. "description too short") are shown
  inline above the form after a successful create/patch.
- Read-only mode when the current user lacks EDIT — the form still renders
  but inputs are marked `readOnly` and the save/reset buttons are hidden.
- Share via ACL using the existing `GenericGrantAccessDialog` — the
  `ShareSkill` button is gated on the SHARE permission.
- Delete with confirmation, driven by `useDeleteSkillMutation({ id })`.
- Conditional file tree: only rendered when `useListSkillFilesQuery`
  returns > 0 files. The tree groups flat `relativePath` strings into a
  nested view (no `react-arborist` dependency) and supports per-file
  deletion via `useDeleteSkillFileMutation`. Upload is intentionally
  deferred — the backend stubs it at 501 in phase 1.

- New routes: `/skills`, `/skills/new`, `/skills/:skillId`.
- Sidebar accordion (`SkillsAccordion` wrapping `SkillsSidePanel`) added
  to `useSideNavLinks` gated on `PermissionTypes.SKILLS` USE.

The initial UI branch (#12580) shipped a lot of exploration code on top of
a now-superseded placeholder backend. Kept as complementary: the `Skills/`
component tree, translation keys, role descriptions, `PublicSharingToggle`
SKILL mapping, `resources.ts` SKILL config, `useCanSharePublic` SKILL
mapping, and `data-provider/roles.ts` `useUpdateSkillPermissionsMutation`.

Deferred out of this first pass:
- Skill favorites (`useSkillFavorites`, `getSkillFavorites` endpoint) —
  the backend route doesn't exist yet; saving for a follow-up.
- AgentConfig `SkillSelectDialog` integration — the UI branch had this
  gated behind `false &&`; rolled back with the config.
- `InvocationMode` / `CategorySelector` / `parseSkillMd` / tree-node
  mutations — not in the Anthropic skill spec and not in the CRUD API.
- `react-arborist` dependency — replaced with a hand-rolled recursive
  tree built from flat `TSkillFile[]`.

- 38 data-schemas skill model tests: pass
- 25 api skill route tests: pass
- 16 user-controller cleanup tests: pass

* 🔐 feat: Default-On Skills in Interface Config and Role Seeder

The skills accordion was registered in the side nav gated on
`PermissionTypes.SKILLS` USE, but no one was actually seeding that
permission on startup, so a fresh install had the USER role with
zero skill permissions and the accordion never rendered.

Fixes three gaps:

1. `interfaceSchema` in data-provider's `config.ts` had no `skills`
   field at all. Added it alongside the existing agents/prompts shape
   (boolean | { use, create, share, public }) and a default of
   `{ use: true, create: true, share: false, public: false }`.

2. `loadDefaultInterface` in data-schemas passed every interface key
   through to the loaded config EXCEPT `skills`. Added the one-line
   passthrough so `appConfig.interfaceConfig.skills` is actually
   populated on boot.

3. `updateInterfacePermissions` in packages/api/src/app/permissions.ts
   seeds role permissions from the interface config on every restart.
   Added:
   - `SKILLS` case to `hasExplicitConfig`
   - `skillsDefaultUse/Create/Share/Public` extraction (mirrors
     prompts/agents)
   - `PermissionTypes.SKILLS` block in `allPermissions` that falls
     through config → roleDefaults → schema default, same pattern as
     AGENTS and PROMPTS
   - `SKILLS` entry in the share-backfill array so that pre-existing
     SKILL role docs missing SHARE/SHARE_PUBLIC get them filled on the
     next restart

Test expectations updated: seven `expectedPermissionsFor(User|Admin)`
blocks in `permissions.spec.ts` now include SKILLS, matching the
role-default values (USER: use+create true, share/public false;
ADMIN: all true).

Result: on a fresh install, a regular USER gets skill USE/CREATE
and the "Skills" accordion shows up in the chat side panel without
any yaml config. Admins can lock it down per role or per tenant via
`interface.skills` in librechat.yaml.

Tests:
- 34 packages/api permissions.spec.ts: pass
- 151 packages/api app tests: pass
- 38 data-schemas skill.spec.ts: pass
- 928 data-provider tests: pass
- 25 api skills.test.js: pass

* ♻️ fix: Resolve Skills UI Review Findings

Addresses the 13 findings from the PR review against the prior commit.

1. **canEdit consistency** — extracted `useSkillPermissions(skill)` as the
   single source of truth for owner/admin/ACL gating. `SkillsView`,
   `SkillForm`, `ShareSkill` all consume it; `SkillFileTree`'s per-file
   delete button now honors admin + EDIT-bit permissions instead of just
   ownership. Unit tests cover owner, admin, editor-ACL, viewer-ACL,
   owner-ACL, loading, and undefined-skill cases.

2. **Disabled submit buttons** — create/edit form submit buttons now set
   native `disabled` (not just `aria-disabled`) during `isLoading`.
   `onSubmit` also guards with an early return when the mutation is still
   in-flight so a duplicate enter-key submit can't create two skills.

3. **Wrong maxLength error message** — description/name `maxLength` rules
   no longer re-use `com_ui_skill_*_required`. Added dedicated
   `com_ui_skill_name_too_long` and `com_ui_skill_description_too_long`
   keys with the literal limit interpolated (`{{0}}`).

4. **Search debouncing** — `SkillsSidePanel` now threads the filter input
   through the existing `useDebounce` hook (250ms) so typing "skills" no
   longer fires six separate list queries.

5. **Frontend test coverage** — added:
   - `tree.test.ts` (9 tests) covering `buildTree` / `nodeKey` edge cases:
     empty input, single root file, multiple roots, nested folders,
     deeply-nested trees, lexicographic sort, empty paths, stable keys
   - `useSkillPermissions.test.ts` (7 tests) covering every precedence
     branch (owner / admin / EDIT / VIEW / owner-ACL / loading / undef)

   Form integration tests proved flaky against react-hook-form's async
   `isValid` with our jest-dom mock setup; deferred to a follow-up PR
   with a proper `@librechat/client` test harness.

6. **Shared `SKILL_NAME_PATTERN`** — promoted the regex plus the four
   length constants (`SKILL_NAME_MAX_LENGTH`,
   `SKILL_DESCRIPTION_MAX_LENGTH`, `SKILL_DESCRIPTION_SHORT_THRESHOLD`,
   `SKILL_DISPLAY_TITLE_MAX_LENGTH`, `SKILL_BODY_MAX_LENGTH`) out of
   `packages/data-schemas/src/methods/skill.ts` and into
   `packages/data-provider/src/types/skills.ts`. The data-schemas
   module now aliases the shared exports so the backend validator and
   the frontend form share one source of truth. Also fixed a latent bug:
   the client regex was stricter than the backend
   (`^[a-z0-9]+(?:-[a-z0-9]+)*$` vs. the real `^[a-z0-9][a-z0-9-]*$`),
   which would have rejected valid names like `foo--bar` client-side.

7. **Removed hardcoded "Claude"** — replaced `com_ui_skill_description_help`
   ("Claude uses this to...") with a new `com_ui_skill_create_subtitle`
   for the form header and `com_ui_skill_description_field_hint`
   ("This is what the model reads to decide...") for the inline hint.
   LibreChat is LLM-agnostic; the old copy misled GPT/Gemini users.

8. **Lifted tree mutation hook** — `useDeleteSkillFileMutation` is now
   instantiated once in `SkillFileTree` (not per `TreeRow`). A
   `TreeContext` provides `onDeleteFile` + `isDeleting` + `canEdit` to
   rows. A 60-node tree used to instantiate 60 mutation hooks; it now
   instantiates one.

9. **List O(n) re-render** — `SkillListItem` no longer reads
   `useParams()` directly. `SkillList` reads the active id once and
   passes `isActive` as a prop, so navigation only re-renders the two
   items whose `isActive` flipped (memo'd), not all N items.

10. **Deduped help text** — the field-level hint and form-level subtitle
    now use different translation keys with distinct copy instead of
    showing the same sentence twice on the same page.

11. **Removed ineffective `useCallback`** — `DeleteSkill.handleDelete`,
    `CreateSkillForm.onSubmit` / `.handleCancel`, `SkillForm.onSubmit`,
    and `SkillFileTree.handleDeleteFile` all wrapped closures around
    React Query `mutation` refs, whose identities change every render.
    Their dep arrays invalidated every render, making the memo a no-op
    with extra overhead. `SkillFileTree` now destructures the stable
    `mutate` function and inlines the arrow inside the memoized
    `contextValue` — one stable reference per deps change.

12. **Import order** — fixed shortest→longest package ordering and
    longest→shortest local ordering across all touched skill files per
    AGENTS.md. `react` always first where imported.

13. **Memoization principle** — documented the rule with inline comments:
    `memo` on components that appear in repeated contexts (`TreeRow`,
    `SkillListItem`) or as children of frequently-re-rendering parents
    (`ShareSkill` / `DeleteSkill` under `SkillForm`'s per-keystroke
    form-state updates). Removed `memo` from `SkillFileTree` since its
    parent `SkillDetailPanel` only re-renders on query-data changes.

- 38 data-schemas skill.spec.ts
- 34 packages/api permissions.spec.ts
- 25 api skills.test.js
- 16 client unit tests (9 buildTree + 7 useSkillPermissions)
- All type-checks + eslint clean on touched files

* 🧹 fix: Skills Duplication, Input Styling, Remove LLM-specific Copy

Three UI fixes from an in-chat review pass:

1. **Sidebar duplication** — `SkillsView` was rendering its own
   `SkillsSidePanel` aside alongside the chat side panel's
   `SkillsAccordion`, so on `/skills` the user saw the skill list
   twice. Fixed by mirroring the `InlinePromptsView` pattern: the
   route content is now just the detail / create panel and the
   chat side panel is the sole list. Added `/skills → /skills/new`
   redirect and a `/skills/new` literal route so `useParams().skillId`
   is `undefined` for "new" (matches prompts).

2. **Name Input styling** — the big floating-label pattern used by
   prompts/agents for the primary name field was replaced with a
   conventional `<Label>` + `<Input>` above it, diverging from the
   rest of the app. Restored the prompts-style `text-2xl` input with
   the peer-focus animated label on both `CreateSkillForm` and
   `SkillForm`. Kept the conventional pattern for description and
   body since they're textareas.

3. **Remove LLM-specific copy from skill translations** — dropped
   `com_ui_skill_description_help` ("Claude uses this to...") and
   the transitional "This is what the model reads..." phrasing.
   Field hint is now a neutral "Be specific about when this skill
   should apply." and the create-page subtitle is a neutral "Author
   a new skill your agents can invoke." LibreChat is LLM-agnostic;
   baking product names into user-facing copy is wrong outside the
   `com_endpoint_anthropic_*` keys where the setting actually only
   applies to Claude models.

Side-effect: the `SkillDetailView` wrapper in `SkillsView` now only
renders the file-tree aside when the skill has > 0 files — same
conditional-tree behavior as before, just scoped to this route
instead of also trying to also render a list sidebar.

- 16 client skill tests still pass
- Type-check + eslint clean on touched files

* 🎁 feat: Restore Skills UI from PR #12580

Brings back everything the original UI PR (#12580, commit da039917c)
shipped that my earlier rebase dropped. Verbatim restores where possible;
adapts the new hooks/types where the backend contract has shifted.

**Scoped-out / gated-off (now restored as inert UI scaffolding):**
- `hooks/useSkillFavorites.ts` + `utils/favoritesError.ts` + the
  `useGetSkillFavoritesQuery` / `useUpdateSkillFavoritesMutation` additions
  in `data-provider/Favorites.ts`. The backend route doesn't exist yet —
  the data-service functions resolve with empty arrays so the Star UI is a
  visual-only no-op until phase 2.
- `dialogs/SkillSelectDialog.tsx` + the "Add Skills" section in
  `SidePanel/Agents/AgentConfig.tsx` (still gated behind the original
  `false &&`) + `skills?: string[]` on `AgentForm` / `Agent` /
  `AgentCreateParams` / `AgentUpdateParams` + the `skills: []` entry in
  `defaultAgentFormValues`.
- `TUserFavorite.skillId` reserved on the shared favorites type.

**Concept-is-gone / deleted-types (restored as UI-only types + stubs):**
- `InvocationMode` enum and `TSkillNode`, `TSkillTreeResponse`,
  `TCreateSkillNodeRequest`, `TUpdateSkillNodeRequest` types in
  `packages/data-provider/src/types.ts`. UI-facing only; the backend flat
  `TSkillFile[]` contract is unchanged.
- `TSkill.invocationMode?: InvocationMode` as an optional field. Forms
  read/write it in local state and deliberately drop it from the PATCH
  payload until the backend column lands.
- `tree/SkillFileTree.tsx` (`react-arborist`-based), `SkillTreeNode.tsx`,
  `TreeToolbar.tsx`, `SkillFileEditor.tsx`, `SkillFilePreview.tsx` — full
  filesystem-style browser UI restored verbatim.
- `data-provider/Skills/tree-queries.ts` + `tree-mutations.ts` hooks
  (`useGetSkillTreeQuery`, `useCreateSkillNodeMutation`, etc.). The
  `data-service` stubs them: `getSkillTree` returns `{ nodes: [] }`,
  `createSkillNode` / `updateSkillNode` / `updateSkillNodeContent` return
  synthetic node shapes, `deleteSkillNode` resolves void. Hooks compile
  and run; tree is empty until phase 2 wires a real backend.
- `MutationKeys.createSkillNode` / `updateSkillNode` / `deleteSkillNode` /
  `updateSkillNodeContent` + `CreateSkillNodeBody` /
  `UpdateSkillNodeVariables` / `DeleteSkillNodeBody` /
  `UpdateSkillNodeContentVariables` types.
- `QueryKeys.skillTree` / `skillNodeContent` / `skillFavorites` /
  `favorites` and the `skillTree()` endpoint helper.

**Scope-simplified (restored with minimal adaptation):**
- `display/SkillDetailHeader.tsx` + `display/SkillDetail.tsx`. Header now
  falls back to `InvocationMode.auto` when `skill.invocationMode` is
  undefined.
- `forms/SkillContentEditor.tsx` — click-to-edit markdown preview toggle
  for the SKILL.md body field. Wired into both `CreateSkillForm` and
  `SkillForm` replacing the plain `<TextareaAutosize>`.
  (Needed `@ts-ignore` on `remarkPlugins` / `rehypePlugins` for the same
  `PluggableList` vs `Pluggable[]` shape drift `MarkdownLite.tsx` already
  works around.)
- `forms/InvocationModePicker.tsx` + `forms/CategorySelector.tsx` — the
  auto/manual/both dropdown and the skill category selector. Wired into
  both forms inside a `FormProvider` so the Controller-based widgets can
  read `useFormContext`. `category` flows to the PATCH / POST payload as
  before; `invocationMode` is UI-only per the type note above.
- `buttons/CreateSkillMenu.tsx` + `utils/parseSkillMd.ts` — dropdown with
  AI / Manual / Upload SKILL.md entries + the YAML frontmatter parser for
  the upload path. `CreateSkillForm.defaultValues` now accepts the parsed
  shape, so the upload → redirect → pre-populated form flow works again.
- `buttons/AdminSettings.tsx` — admin permissions dialog. Uses the
  existing `useUpdateSkillPermissionsMutation` which was already wired.
- `sidebar/FilterSkills.tsx` — restored filter + AdminSettings +
  CreateSkillMenu wrapper. `SkillsSidePanel.tsx` is back to the original
  `FilterSkills`-based layout.
- `lists/SkillList.tsx` + `lists/SkillListItem.tsx` — restored verbatim.
- `layouts/SkillsView.tsx` — restored the full tree + file editor + file
  preview layout. The chat side panel keeps its own accordion list; this
  view is the inline detail experience.
- `hooks/Generic/useUnsavedChangesPrompt.ts` — route-leave guard hook.

- `useGetSkillByIdQuery` is aliased to `useGetSkillQuery` so restored
  components (`SkillsView`, `SkillForm`) that import the old name resolve
  to the new hook.
- `SkillSelectDialog` + `AgentConfig` coerce `skillsData?.skills` instead
  of `.data` (list response shape drift from the CRUD PR).
- `CreateSkillForm` / `SkillForm` wrap their JSX in `FormProvider` so the
  restored `CategorySelector` and `SkillContentEditor` components —
  which read `useFormContext` — work inside the existing forms without
  another refactor.
- `CreateSkillForm.defaultValues` prop accepts `Partial<Values> &
  { invocationMode?: unknown }` so the upload flow's
  `{ name, description, invocationMode }` shape passes through cleanly.
- `SkillsView` route map gains `/skills/:skillId/edit` and
  `/skills/:skillId/file/:nodeId` so the tree-navigation URLs the original
  view produces actually resolve.
- `client/package.json` gains `react-arborist@^3.4.3`.
- ~60 translation keys the restored files reference — invocation labels,
  edit/create page titles, file editor chrome, tree toolbar tooltips,
  favorites, admin allow-settings, unknown-file-type, sr_public_skill,
  delete/rename _var variants — all added to `en/translation.json`.

- Prompts-style floating-label name input — kept from my earlier commit
  so it matches the rest of the app (user reviewed and approved that
  styling). Hidden skill-body textarea is replaced by `SkillContentEditor`
  in both forms.

- 38 data-schemas skill.spec.ts
- 34 packages/api permissions.spec.ts
- 25 api skills.test.js
- 7 client useSkillPermissions.test.ts
- Type-check: pre-existing error count (188) dropped to 120 because my
  restorations fixed some previously-broken field types.

* chore: Update package-lock.json to include react-arborist and memoize-one

* feat: Add support for react-arborist in Vite configuration

This update introduces a new condition in the Vite configuration to handle the 'react-arborist' package, ensuring it is properly recognized during the build process. This change enhances compatibility with the recently added 'react-arborist' dependency in the project.

* 🩹 fix: Hide InvocationMode, Fix SkillContentEditor Click-to-Edit

1. Hide InvocationModePicker from both CreateSkillForm and SkillForm.
   Component stays on disk for when the backend lands the column.

2. Fix "Click to edit" doing nothing on SkillContentEditor. The
   `onBlur={() => setIsEditing(false)}` on the TextareaAutosize was
   racing with `autoFocus` — React renders the textarea, autoFocus
   fires, then a layout/reconciliation blur fires immediately,
   bouncing back to preview mode before the user can interact.
   Removed onBlur; users toggle via the header button or Escape key.

* 🎨 feat: Reader-First Skills UI — Match Claude.ai Layout

Reworks the Skills UI from form-first to reader-first, matching
Claude.ai's skill detail pattern.

**Default view is now read-only.** Clicking a skill in the sidebar
navigates to `/skills/:id` which renders `SkillDetail` — a clean
content view with:
- Skill name as the primary heading
- Metadata row: "Added by" + "Last updated" (formatted date)
- Description block
- Rendered SKILL.md body in a bordered card with a source/rendered
  toggle (eye + code icons, matching Claude.ai's segmented control)

No form fields, no save/cancel buttons. The user reads the skill
first and takes action deliberately.

**Create is now a dialog.** The `/skills/new` route is gone.
`CreateSkillMenu` (the + dropdown in the sidebar) now opens
`CreateSkillDialog` — a minimal modal with name, description, and
instructions fields. Upload-from-file still works: parse → populate
dialog → create. Matches Claude.ai's "Write skill instructions"
modal.

**Edit is behind an action.** The detail view shows an "Edit" button
(permission-gated) that navigates to `/skills/:id/edit`, rendering
the existing `SkillForm`. The edit route is preserved for direct
linking.

**Navigation goes to detail, not edit.** `SkillListItem` now
navigates to `/skills/:id` (detail) instead of `/skills/:id/edit`.

- `display/SkillMarkdownRenderer.tsx` — shared ReactMarkdown
  component extracted from `SkillContentEditor`. Same remark/rehype
  plugins, no form dependency.
- `display/SkillDetail.tsx` — the reader-first view (replaces the
  old thin wrapper).
- `dialogs/CreateSkillDialog.tsx` — OGDialog modal for skill
  creation.

- `layouts/SkillsView.tsx` — gutted and rebuilt. Three states:
  no-skill (empty state), skillId (SkillDetail), skillId+edit
  (SkillForm). Removed full-page CreateSkillForm, removed TreeView.
- `buttons/CreateSkillMenu.tsx` — opens dialog instead of navigating
  to `/skills/new`. Upload flow: parse → set dialog defaults → open.
- `lists/SkillListItem.tsx` — navigate to detail, not edit.
- `routes/index.tsx` — removed `/skills/new` and file/nodeId routes;
  `/skills` renders SkillsView directly (empty state).
- `display/index.ts`, `dialogs/index.ts` — added new exports.
- `locales/en/translation.json` — added ~10 new keys for metadata,
  toggle labels, dialog title, empty state.

* 🩹 fix: SkillContentEditor click-to-edit z-index — button was z-0 behind rendered content

* 🩹 fix: Align Edit button size with Share/Delete (size-9)

* 🎨 feat: Claude.ai-Style Skill List Panel

Rewrites the skills sidebar to match Claude.ai's panel layout:

- Header: "Skills" title + search icon (toggles input) + add icon
  (opens CreateSkillDialog directly, no dropdown menu)
- Collapsible "Skills" section with chevron toggle
- Skill items: 24px icon badge (rounded square with ScrollText icon)
  + name only. No description text in the list — that lives in the
  detail view. Active item gets highlighted bg + bold font.
- Removed AdminSettings button from sidebar header — admin config
  is accessible via the admin dashboard, not cluttering every user's
  skill list.
- Removed FilterSkills wrapper (was Filter + AdminSettings +
  CreateSkillMenu). The search + create are now inline in the panel
  header.

Files changed:
- sidebar/SkillsSidePanel.tsx — full rewrite
- sidebar/SkillsAccordion.tsx — simplified wrapper
- lists/SkillList.tsx — collapsible section, no description
- lists/SkillListItem.tsx — icon badge + name, memo'd

* 🎨 fix: Align Skills UI Styling with Prompts Patterns

Style alignment pass based on direct comparison with claude.ai and
the existing prompts preview dialog.

SkillsSidePanel search now replaces the title in the header row when
toggled (search icon + input + X close), matching Claude.ai's pattern.
Previously it pushed a separate input below the header, wasting
vertical space. Close button clears the search term.

Replaced `text-text-tertiary` with `text-text-secondary` across
SkillDetail, SkillList, SkillForm, CreateSkillForm, CreateSkillDialog,
SkillContentEditor. Tertiary was too dark / low contrast.

SkillList section chevron label now reads "Personal skills" (matching
Claude.ai) via the existing `com_ui_my_skills` key, instead of the
generic "Skills" which duplicated the header.

Aligned with `PromptDetailHeader` styling:
- 48px round icon (ScrollText in bg-surface-secondary circle)
- Name + public badge in the icon row
- Metadata below the icon: User icon + author, Calendar icon + date
  (text-xs text-text-secondary with gap-3, matching prompts exactly)
- Description uses the same label-above-text pattern as prompts
- Content card uses `bg-transparent` border (not bg-surface-primary-alt)
- Toggle buttons use size-5 icons and text-text-secondary for inactive

Changed from `max-w-lg p-0` to `max-w-5xl` with the same max-height
and padding pattern as the prompts PreviewPrompt dialog:
`max-h-[80vh] p-1 sm:p-2 gap-3 sm:gap-4`. Close button now renders
via default OGDialogContent behavior (removed showCloseButton=false).

* 🩹 fix: SkillDetail fills parent height, tighter spacing (px-6 pb-6 gap-2)

* 🩹 fix: Align Skills panel header padding (px-4) with list content below

* 🩹 fix: Reduce Skills header top padding (pt-2) to align with sidebar icon strip

* 🩹 fix: Tighten Skills header (py-2) and detail top (py-2) to align with sidebar icons and match edit view

* 🩹 fix: Offset SidePanel Nav pt-2 with -mt-2 on SkillsAccordion so Skills header aligns with icon strip

* 🛠️ fix: Increase Node memory limit for production build in package.json

* 🩹 fix: Remove top padding from SkillDetail header row (py-2 → pb-2)

* 🏗️ refactor: Move pt-2 from SidePanel/Nav wrapper to each panel

Removed the global `pt-2` from `SidePanel/Nav.tsx` and pushed it
into each panel's own top-level wrapper. This lets each panel own
its vertical alignment independently — Skills can sit flush at the
top to align with the sidebar icon strip, while other panels keep
their original spacing.

Panels updated with `pt-2`:
- PromptsAccordion (via className on PromptSidePanel)
- BookmarkPanel
- FilesPanel
- MemoryPanel
- MCPBuilderPanel
- AgentPanel (form wrapper)
- AssistantPanel (form wrapper)
- ParametersPanel (already had pt-2)

SkillsAccordion: removed the -mt-2 hack, now naturally flush.

* 🧹 fix: Align CreateSkillDialog field styling + remove 19 unused i18n keys

Dialog fields: all three inputs now use consistent `rounded-xl
border-border-medium px-3 py-2 text-sm` styling. Replaced the
`<Input>` component with a plain `<input>` to avoid the component's
built-in `rounded-lg border-border-light` overriding the dialog's
border style. Labels use `font-medium` for consistency.

Removed 19 unused translation keys from translation.json:
com_ui_skill_body, com_ui_skill_body_placeholder,
com_ui_skill_create_subtitle, com_ui_skill_file_delete_confirm,
com_ui_skill_file_delete_error, com_ui_skill_file_deleted,
com_ui_skill_files_empty, com_ui_skill_files_multi_hint,
com_ui_skill_list, com_ui_skill_load_error,
com_ui_skill_resize_file_tree, com_ui_skill_select_file,
com_ui_skill_select_file_desc, com_ui_skills_load_error,
com_ui_add_first_skill, com_ui_create_skill_page,
com_ui_edit_skill_page, com_ui_save_skill, com_ui_no_skills_title

* 🎁 feat: Upload Skill Dialog + Simplified Create Menu

New `UploadSkillDialog` matching Claude.ai's upload modal:
- Dashed drop zone with drag-and-drop support
- Accepts .md, .zip, .skill files
- Phase 1: processes .md files (parses YAML frontmatter → creates
  skill with body as the full file content)
- Shows file requirements below the drop zone
- On success: navigates to the new skill's detail view

`CreateSkillMenu` now has two flat options (no sub-menu):
- "Write skill instructions" → opens `CreateSkillDialog`
- "Upload a skill" → opens `UploadSkillDialog`

Removed the disabled "Create with AI" option and the old file input
hidden-element approach. The sidebar `+` button now renders
`CreateSkillMenu` directly instead of a standalone create dialog.

- Removed 5 unused i18n keys (com_ui_skill_added_by,
  com_ui_skill_last_updated, com_ui_skills_add_first,
  com_ui_skills_filter_placeholder, com_ui_skills_new)
- Tightened metadata gap in SkillDetail (mt-1 → mt-0.5)
- Added 7 new upload-related i18n keys

* 🔒 feat: Zip/Skill File Upload Support with Safety Limits

Rewrites UploadSkillDialog to properly handle all three accepted
file types:

- `.md` — reads as text, parses YAML frontmatter, creates skill
- `.zip` / `.skill` — reads as ArrayBuffer, extracts with JSZip,
  finds SKILL.md (at root or one level deep), parses its content,
  creates skill. Shows spinner during processing.

Security guards against zip bombs:
- MAX_ZIP_SIZE: 50MB compressed file limit
- MAX_ENTRIES: 500 file limit inside the archive
- Path traversal rejection: skips entries with `..` or leading `/`
- SKILL.md search limited to depth ≤ 2 segments

Added `jszip@^3.10.1` to client dependencies (already in the
monorepo's node_modules from backend usage).

The name is inferred from the zip filename if SKILL.md frontmatter
doesn't have one (e.g. `skills-autofix.zip` → `skills-autofix`).

* 🚀 feat: Backend Skill Import + Live File Upload Endpoints

New endpoint that accepts a single multipart file (.md, .zip, .skill)
and creates a skill with all its files in one request:

- **.md**: parse YAML frontmatter → create skill with body
- **.zip / .skill**: extract with JSZip, find SKILL.md (root or one
  level deep), create skill from its content, then persist every
  additional file via `upsertSkillFile` + local file storage strategy.
  Returns the created skill + an `_importSummary` with per-file
  results.

Security:
- 50MB compressed file size limit (multer)
- 500 max entries in archive
- 10MB per individual file
- Path traversal rejection (no `..`, no absolute, validated charset)
- File type filter: only .md/.zip/.skill accepted
- Rate limited via existing `fileUploadIpLimiter` + `fileUploadUserLimiter`

Handler lives in `packages/api/src/skills/import.ts` with injectable
deps (`createSkill`, `upsertSkillFile`, `saveBuffer`) for testability.

Replaced the 501 stub with a real handler:
- Accepts multipart FormData with `file` + `relativePath`
- Saves file via local storage strategy
- Calls `upsertSkillFile` to persist the SkillFile record
- Returns the upserted document
- Rate limited, ACL-gated (EDIT permission required)
- 10MB per file limit

`UploadSkillDialog` now sends the file to `/api/skills/import` via
`dataService.importSkill(formData)` — no more client-side JSZip.
Removed `jszip` from client dependencies (only backend needs it).

Added `importSkill()` in data-service + `importSkill()` endpoint
builder in api-endpoints.

Updated the file upload test from expecting 501 stub to expecting
400 "no file provided" (live validation). All 25 skill route tests
pass.

* 🔒 fix: Complete Import Handler — Validation, Ownership, Error Surfacing

Fixes several gaps in the skill import flow:

1. **Skill validation now runs and surfaces properly.** The import
   handler calls the real `createSkill(CreateSkillInput)` which runs
   `validateSkillName`, `validateSkillDescription`, `validateSkillBody`.
   Validation errors (SKILL_VALIDATION_FAILED) are caught and returned
   as 400 with the issue messages. Duplicate-key errors return 409.
   Previously all errors were swallowed into a generic 500.

2. **`authorName` is now populated.** The `CreateSkillInput` requires
   `authorName` which was missing — resolved from `req.user.name ??
   req.user.username ?? 'Unknown'`, matching the existing create handler.

3. **SKILL_OWNER permission is granted after import.** Calls
   `grantPermission` with `AccessRoleIds.SKILL_OWNER` so the uploader
   can edit/delete/share the imported skill. This was entirely missing —
   imported skills would have been ownerless.

4. **`tenantId` propagated.** Both the skill and each SkillFile record
   receive `req.user.tenantId` for multi-tenant deployments.

5. **SkillFile records are created in the DB.** Each non-SKILL.md file
   in the zip is saved to file storage via `saveBuffer` and recorded
   via `upsertSkillFile`, which validates the relativePath, infers the
   category from the path prefix, and atomically bumps the skill's
   `fileCount` and `version`.

Import deps now include `grantPermission` from PermissionService,
injected in `api/server/routes/skills.js`.

* 🐛 fix: Import grant uses accessRoleId (not roleId) — fixes skill not appearing in list

* 🎨 fix: Cache invalidation, file tree, frontmatter rendering

Three fixes for the skill detail view:

1. **Cache invalidation after import.** UploadSkillDialog now calls
   `queryClient.invalidateQueries([QueryKeys.skills])` after a
   successful import so the sidebar list picks up the new skill
   without requiring a page refresh.

2. **File tree in detail view.** When a skill has `fileCount > 0`,
   the detail view now queries `useListSkillFilesQuery` and renders
   a file list below the body card — SKILL.md first, then folders
   and root files. Icons: Folder for directories, FileText for files.

3. **Frontmatter stripped and rendered as metadata.** YAML frontmatter
   (`---\nversion: 0.1.0\ntriggers: ...\n---`) is now parsed out of
   the body before markdown rendering. The `name` and `description`
   fields are skipped (already shown in the header). Remaining fields
   (version, triggers, dependencies, etc.) are displayed in a
   Claude.ai–style grid: label on the left, value on the right,
   above the rendered markdown content. Source view still shows the
   full raw body including frontmatter.

* 🩹 fix: Always fetch skill files — fileCount may be stale in cached skill object

* 🌳 feat: Inline File Tree in Sidebar Skill List

Moves the file tree from the bottom of SkillDetail into the sidebar
list, matching Claude.ai's pattern:

- Multi-file skills show a chevron toggle on the right side of the
  skill list item
- Clicking the chevron expands an inline file tree below the skill
  name: SKILL.md first, then folders (with folder icon + right
  chevron) and root files
- File list is fetched lazily (only when expanded) via
  useListSkillFilesQuery
- Clicking a file navigates to the skill detail view
- Files section removed from SkillDetail — the sidebar is now the
  sole file tree location, keeping the detail panel clean

SkillDetail cleaned up: removed groupFiles helper, file-related
state, useListSkillFilesQuery import, FileText/Folder icon imports.

* 🌲 feat: Virtualized inline file tree with react-vtree

Replace hand-rolled recursive FolderRow/FileRow buttons with a proper
virtualized FixedSizeTree from react-vtree for the sidebar skill list.
Dynamic height tracks open folders; capped at 350px with smooth
expand/collapse transitions.

* chore: Remove no longer used SkillFileTree and SkillTreeNode components

* chore: Update Vite config to replace 'react-arborist' with 'react-vtree' for module resolution

* feat: Skill file content viewing with lazy DB caching

- Add `skills` field to `fileStrategiesSchema` so operators can
  configure a dedicated storage backend for skill files. Falls back
  by type (image/document) when unset.
- Fix hardcoded `FileSources.local` in skill save/import — now uses
  the resolved strategy via `getFileStrategy(req.config, { context })`.
- Replace 501 download stub with real handler that streams from any
  storage backend and returns JSON `{ content, mimeType, isBinary }`.
- Binary detection (null-byte + non-printable ratio on first 8 KB)
  flags files on first read so they're never re-fetched.
- Text content ≤ 512 KB is cached in the SkillFile MongoDB document;
  subsequent reads skip storage entirely.
- Clicking a skill row now expands inline files (not just chevron).
- Clicking a file navigates to `?file=<path>` and renders content
  in a new SkillFileViewer (markdown, code, images, binary placeholder).

* chore: Remove react-window and its type definitions from package.json and package-lock.json

- Deleted `react-window` and `@types/react-window` dependencies from both `package.json` and `package-lock.json` to streamline the project and reduce unnecessary bloat.

* fix: Build errors — remove endpoints import, fix Uint8Array cast

- Replace `import { endpoints }` (not public) with inline URL in
  SkillFileViewer
- Remove `as Uint8Array` cast in stream chunk handling
- Extend getSkillFileByPath return type with content/isBinary to
  decouple from data-schemas build artifact resolution

* chore: Remove 8 unused i18next keys

com_ui_create_skill_ai, com_ui_create_skill_manual,
com_ui_delete_folder_confirm_var, com_ui_delete_skill,
com_ui_delete_skill_confirm_var, com_ui_delete_var,
com_ui_rename_var, com_ui_skill_files

* fix: Add configMiddleware to skills router, handle SKILL.md in viewer

- Add configMiddleware to skills router so req.config is populated
  when getLocalFileStream (or any strategy) reads file paths.
- Handle SKILL.md in download handler — serves skill.body directly
  from the Skill document instead of looking for a SkillFile record.
- Clicking SKILL.md in sidebar tree now opens the file viewer
  (matching Claude.ai behavior: file view vs default detail view).

* ci: Run unit tests on PRs to any branch

Remove the branches filter from both test workflows so contributor
PRs targeting feature branches (not just main/dev) get CI coverage.
Path filters are kept so tests only run when relevant files change.

* fix: Update skills route tests for download handler changes

- Mock configMiddleware (sets req.config for file storage access)
- Mock getStrategyFunctions and getFileStrategy (storage strategy deps)
- Replace 501 stub test with SKILL.md content test + 404 test

* fix: Auto-expand files, frontmatter parsing, select-none, prefetch

- Auto-expand file tree when navigating directly to a skill URL
- Prefetch files for the active skill (eliminates first-expand lag)
- Fix frontmatter parser to handle multi-line YAML list values
  (triggers field was missing because it uses list syntax)
- SkillFileViewer now parses frontmatter for .md files — shows
  structured grid + rendered body (matching SkillDetail's display)
  with source/rendered toggle
- Add select-none to all sidebar skill and file tree buttons

* refactor: Derive expanded state from isActive instead of useEffect

Replace useEffect sync with deterministic derivation:
expanded = hasFiles && (isActive || !collapsed)

Active skill is always open. collapsed is a manual toggle that
only takes effect on non-active items.

* fix: Remove empty space above body card — overlay view toggle

Move the rendered/source toggle from a dedicated row (40px of empty
space) to an absolute-positioned overlay in the card's top-right
corner, matching Claude.ai's layout.

* fix: Remove header bars from content editors — overlay action buttons

Collapse the full-width header bars ("Skill Content", "Text") in
SkillContentEditor, PromptTextCard, and PromptEditor. Action buttons
(edit/save toggle, copy, variables) are now absolute-positioned in
the card's top-right corner, reclaiming ~46px of vertical space.

* fix: Spinner visibility in file viewer — use text-text-secondary

* fix: Address review findings — security, correctness, code quality

Codex P1: Use $unset instead of undefined to clear cached content
and isBinary fields on file re-upload (Mongoose strips undefined).

Codex P2: Match skill-file validation errors by error.code instead
of error.message substring.

F1: Zip bomb defense — track cumulative decompressed bytes (500 MB
cap), check declared uncompressed size before buffering each entry.

F2: Remove misleading "atomically" from import handler JSDoc.

F3: Static import for isBinaryBuffer instead of dynamic import().

F4: Replace console.error with logger in upload handler.

F6: Add multer error handler middleware to skills router.

F7: Move React import to top of SkillDetail.tsx.

F9: Fix variable shadowing (trimmed → item) in parseFrontmatter.

F11: Replace JSON.parse(JSON.stringify()) with toJSON() for
Mongoose document serialization.

F12: Remove dead dynamic import('fs') fallback (memoryStorage
always provides file.buffer).

F13: Hoist MIME_MAP to module scope to avoid per-call allocation.

F16: Share single multer.memoryStorage() instance.

* fix: Follow-up review — close zip bomb gap, fix error handler

F1: Add post-decompression cumulative byte check with break (the
pre-decompression check relies on undocumented JSZip internals
that may be absent; this closes the gap unconditionally).

F2+F3: Multer error handler now forwards non-multer errors via
next(err) instead of swallowing them. Also catches file filter
rejections (plain Error, not MulterError) by message prefix.

F4: Move isBinaryBuffer import to local imports section per
CLAUDE.md import order rules.

F5: Simplify dead toJSON branch — createSkill returns a POJO.

* nit: Link filter error message to handler prefix check

* feat: Accordion expansion + active file highlight in sidebar

- Only one skill's file tree can be expanded at a time (accordion).
  Expansion state lifted from SkillListItem to SkillList.
- Selected file gets bg-surface-active highlight in the tree.
  Skill row uses subtle style (no background) when a file is active,
  matching Claude.ai's pattern where the file — not the skill —
  carries the selection state.

* style: Adjust margin for file tree in SkillListItem component

- Reduced left margin from 10 to 5 for improved layout consistency in the file tree display.

* fix: TS error on FileTreeNode, nested ternary, chevron collapse

- Make style prop optional to match react-vtree's NodeComponentProps
- Flatten nested ternary for skill row active styles
- Skill row click expands (but doesn't collapse) files + navigates
- Chevron click explicitly toggles collapse (matching Claude.ai
  where clicking the chevron is how you collapse files)

* fix: Upload basePath, reject SKILL.md uploads, add skills permission route

- Pass basePath: 'uploads' in per-file upload handler (was defaulting
  to 'images' path, inconsistent with the import flow).
- Reject uploads targeting SKILL.md (reserved path — download handler
  special-cases it to return skill.body, making an uploaded file
  unreachable via the API).
- Add skills entry to roles router permissionConfigs so PUT
  /api/roles/:roleName/skills actually reaches a handler instead
  of returning 404.

* feat: Expand content area, move controls to header, reduce padding

Default detail view:
- Remove rounded-xl bordered card wrapper — content flows directly
  into the article, capitalizing on full screen width
- Move eye/code toggle inline with the divider row
- Reduce px-6/pb-6 to px-4/pb-4

File viewer:
- Move eye/code toggle from card overlay to the header bar
- Add copy-to-clipboard button for text files in the header bar
- Remove rounded-xl bordered card wrapper for markdown content
- Remove bordered pre wrapper for non-markdown text
- Reduce px-6/py-4 to px-4/py-3

Both views maximize content space over decorative chrome.

* fix: Stable header height, restore some padding

- Fix layout shift in file viewer header: use fixed h-10 so the
  bar height stays constant whether the eye/code toggle renders
  (markdown) or not (plain text).
- Bump content padding from px-4/py-3 back to px-5/py-4 in both
  views — the previous reduction was too aggressive.

* fix: Grant rollback, path validation, error format, dead code cleanup

F2: grantOwnership now rolls back (compensating delete) on failure,
matching the create handler. Both markdown and zip import paths
check the result and return 500 on grant failure.

F4: Upload handler validates relativePath with regex + traversal
check before calling downstream upsertSkillFile.

F5: Document JSZip _data.uncompressedSize as best-effort; the
post-decompression cumulative check is the real safety net.

F10: Standardize all upload handler error responses to { error }
(was { message }, inconsistent with handlers.ts).

F13: Single-pass fileResults accumulation in import handler.

F1-5: Remove dead uploadFileStubHandler (no route references it).

Codex P2: Fix delete nav from /skills/new to /skills.

F12: Use cn() in UploadSkillDialog instead of template literals.

* perf: Stream-first binary detection + O(1) public skill check

F1: Download handler now reads only the first 8 KB for binary
detection. If binary, the stream is destroyed immediately without
buffering the remaining file. Text files continue reading for
caching. Eliminates buffering up to 10 MB per request for binary
files under concurrent load.

F7: Single-skill GET and PATCH now use hasPublicPermission (O(1)
ACL lookup) instead of getPublicSkillIdSet (queries ALL public
skill IDs). The list handler still uses the Set approach since it
serializes multiple skills. serializeSkill/serializeSkillSummary
now accept boolean | Set for flexibility.

* fix: Update test to match { error } response format

* fix: Critical stream truncation bug, grantedBy, error format

NF-1 (CRITICAL): Rewrite binary detection to single for-await loop.
Breaking out of for-await-of destroys the stream via iterator.return(),
so the previous two-loop approach silently truncated text files > 8KB.
Now: one loop collects chunks, checks binary after 8KB accumulated,
and either destroys+returns (binary) or continues reading (text).

NF-2: Add grantedBy to import handler's grantPermission call and
interface (was missing, inconsistent with create handler).

NF-3: Standardize all import handler error responses from { message }
to { error }, matching handlers.ts convention. Update client's
UploadSkillDialog to read response.data.error accordingly.

* fix: Prefer specific validation message over generic error field

* fix: YAML quote stripping, saveBuffer null guard, dot segment rejection

- Strip surrounding YAML quotes from frontmatter values so
  name: "my-skill" parses as my-skill (not "my-skill" with quotes
  that fails the name validator).
- Guard resolveSkillStorage against backends with saveBuffer: null
  (e.g. OpenAI/vector strategies) — throws a descriptive error
  caught by the handler's try/catch instead of a TypeError.
- Tighten upload path validation to reject . segments (e.g.
  docs/./a.md) matching the model-layer validator, preventing
  storage writes for paths the DB will reject.

* fix: Orphan cleanup, stream errors, malformed zip, cache latency

F1: Upload handler now deletes the stored blob if the subsequent
DB upsert fails, preventing orphaned files on disk/cloud.

F2: Multer error handler returns { error } (was { message }).

F3: Wrap JSZip.loadAsync in try/catch — malformed zip returns 400
instead of falling through to 500.

F4: Raw download stream gets an error handler — logs the error and
destroys the response if headers were already sent.

F8: Strip leading hyphens from inferred skill name so filenames
like _my-skill.zip don't produce -my-skill (invalid name pattern).

F9: Fire-and-forget all updateSkillFileContent cache writes so the
response is sent immediately. Cache failures are logged but don't
block or fail the read.

* fix: Import orphan cleanup + Content-Disposition sanitization

Finding A: Add deleteFile dep to ImportSkillDeps. The per-file loop
in handleZip now cleans up stored blobs when upsertSkillFile fails,
closing the second half of the F1 orphan fix (upload handler was
already fixed).

Finding B: Sanitize filename in Content-Disposition header for raw
downloads — strip quotes, backslashes, and newlines to prevent
header injection from user-uploaded filenames.

* security: Prevent stored XSS via raw file downloads

Non-image files served via ?raw=true now use Content-Disposition:
attachment (force download) instead of inline. An uploaded .html or
.svg file served inline from the LibreChat origin could execute
scripts with access to the user's session — this closes that vector.

Images stay inline (needed for <img> rendering in SkillFileViewer).
X-Content-Type-Options: nosniff added to prevent MIME sniffing.

* security: Block SVG XSS — allowlist safe raster MIME types for inline

SVG (image/svg+xml) passed the startsWith('image/') check and was
served inline, but SVG is a scriptable format — embedded <script>
tags execute in the LibreChat origin. Replace the prefix match with
a Set of safe raster-only MIME types (png, jpeg, gif, webp, avif,
bmp). SVGs and any future scriptable image/* subtypes now get
Content-Disposition: attachment (forced download).

* fix: Cap JSON text response at 1MB, consistent md name inference

F3: Text files > 1MB now return { isBinary: false } with no content
field, forcing the client to use ?raw=true for download. Prevents
buffering 10MB files into heap for JSON serialization. Frontend
shows a download fallback when content is absent.

F4: handleMarkdown now infers skill name from filename (same as
handleZip) when frontmatter has no name, instead of rejecting
with 400. Consistent behavior across import paths.

F1 (reviewer concern): upsertSkillFile is NOT affected — it uses
{ new: false } for insert-vs-replace detection but does a follow-up
findOne (lines 855-859) to return the post-upsert document.

* fix: deleteFile arg shape, raw URL base path, hoist SAFE_INLINE_MIMES

Codex P2: deleteFile expects { filepath } object, not a raw string.
Both upload handler cleanup and import handler cleanup now pass
{ filepath } to match the strategy contract (deleteLocalFile,
deleteFileFromS3 all expect a file object).

Codex P2: Raw download URL in SkillFileViewer now uses apiBaseUrl
prefix so subpath deployments (/chat, etc.) resolve correctly.

NIT: Hoist SAFE_INLINE_MIMES Set to factory scope — was re-allocated
per raw download request inside the if block.

* fix: Remove inert cache write for large text files, localize aria-label

N2: The { isBinary: false } cache write for text files > 1MB had no
effect — subsequent requests still fell through to stream read since
neither isBinary nor content provided a fast-path short-circuit.
Removed the pointless DB updateOne per request.

N4: Replace hardcoded "Back to skill" aria-label with localize().

* refactor: Extract shared parseFrontmatter, widen deleteFile type

N3: Extract parseFrontmatter into Skills/utils/frontmatter.ts —
single implementation shared by SkillDetail and SkillFileViewer.
Accepts optional skipKeys set so callers control which frontmatter
fields are excluded (SkillDetail skips name/description since
they're shown in the header; other .md files show all fields).

N5: Widen ImportSkillDeps.deleteFile file param from { filepath }
to { filepath; [key: string]: unknown } to signal extensibility
if strategies start accessing additional file properties.

* fix: Advance i past list items for skipped keys, DRY parseSkillMd

Finding A: parseFrontmatter now consumes multi-line YAML list items
before checking skipKeys — prevents list lines from leaking into
subsequent key parsing as spurious fields.

Finding B: parseSkillMd now delegates to the shared parseFrontmatter
instead of re-implementing the same frontmatter scanning loop.
Reduces client-side parseFrontmatter implementations from 3 to 1.

* fix: Call apiBaseUrl(), delete storage blob on file removal

- apiBaseUrl is a function, not a string — call it in the template
  literal so raw download URLs resolve correctly.
- deleteFileHandler now looks up the file record before deleting,
  then fire-and-forget deletes the storage blob via the strategy's
  deleteFile. Previously only the DB record was removed, leaving
  orphaned blobs in local/S3/Firebase/Azure storage.

* fix: Clean up storage blobs when deleting an entire skill

deleteHandler now lists all files for the skill before calling
deleteSkill, then fire-and-forget deletes each blob via the
storage strategy. Previously only per-file deletion cleaned up
blobs — deleting a whole skill left all associated files orphaned
in local/S3/Firebase/Azure storage.

* refactor: useImportSkillMutation hook, fix TSkill[] unsafe cast

- Create useImportSkillMutation in mutations.ts + ImportSkillOptions
  type. UploadSkillDialog now uses the mutation hook instead of
  calling dataService.importSkill directly with manual useState
  loading management. Eliminates unmounted-component state update
  risk and aligns with the React Query mutation pattern used by
  every other mutation in the codebase.

- SkillSelectDialog: replace as unknown as TSkill[] with proper
  TSkillSummary typing. SkillCard props updated to TSkillSummary.
  The dialog only uses summary-level fields (name, description,
  category, author) — the cast was hiding a type mismatch.

* fix: Use saved source for import cleanup, delete old blob on replace

Codex P2: Import cleanup now uses file.source (the backend the file
was actually saved to) instead of re-resolving from config. In mixed
strategy setups, the previous approach could target the wrong backend.

Codex P2: When re-uploading a file to an existing relativePath, the
old blob is now deleted after successful upsert. Previously only the
DB record was replaced, leaving the old storage object orphaned.

* fix: Register PUT /:roleName/skills route in roles router

* fix: Re-read skill after zip file processing for fresh metadata

The import response was built from the skill object created before
the file loop, but each upsertSkillFile bumps version and fileCount.
Clients caching the stale response would get 409 conflicts on first
edit and see incorrect file counts.

Now re-reads the skill via getSkillById after the loop so the
response reflects the current version, fileCount, and updatedAt.

* fix: Size-check SKILL.md before decompression, don't gate on fileCount

P1: SKILL.md was decompressed before any size accounting. A crafted
archive could expand SKILL.md past 10MB before validation ran. Now
checks declared size pre-decompression and actual size post, both
against MAX_SINGLE_FILE_BYTES.

P2: File list query was gated on cached fileCount which can be stale
after mutations. Now fetches files for the active skill regardless
of fileCount. hasFiles derived from fetched data with fileCount as
fallback, so newly uploaded files appear without hard refresh.

* fix: Move files declaration before hasFiles to avoid TDZ error

* security: Stream-decompress zip entries with enforced byte cap

Replace zipEntry.async('nodebuffer') (buffers entire entry before
checking limits) with zipEntry.nodeStream('nodebuffer') piped
through a byte counter that destroys the stream when the per-file
or cumulative limit is exceeded.

Previously, when JSZip's _data.uncompressedSize was absent (the
common case), a high-ratio entry could allocate hundreds of MB
before the post-decompression check caught it. Now decompression
is aborted mid-stream at the exact byte threshold — no entry can
exceed its limit regardless of compression ratio.

* refactor: Reorganize access check for prompts in useSideNavLinks hook

Moved the prompts access check to a new position in the code to improve readability and maintainability. This change ensures that the prompts link is added to the navigation only if the user has the appropriate access, without altering the existing functionality.

963068b112 🧬 feat: Scaffold Skills CRUD with ACL Sharing and File Schema (#12613)
* 🧬 feat: Scaffold Skills CRUD with ACL Sharing and File Schema

Adds Skills as a new first-class resource modeled on Anthropic's Agent
Skills, reusing the existing Prompt ACL stack for sharing. Lays the
groundwork for multi-file skills (SkillFile schema + metadata routes)
without wiring upload processing — single-file skills (inline SKILL.md
body) work end-to-end, multi-file uploads are stubbed for phase 2.

* 🔬 fix: Wire Skill Cleanup, AccessRole Enum, and Express 5 Path Params

CI surfaced four follow-ups from the initial Skills scaffolding commit
that local builds missed:

- AccessRole's resourceType field had a hardcoded enum that didn't
  include `'skill'`, blocking SKILL_OWNER/EDITOR/VIEWER role creation
  in every test that hit the AccessRole model.
- The seedDefaultRoles assertion in accessRole.spec.ts hard-listed the
  expected role IDs and needed the new SKILL_* entries.
- deleteUserController had no cleanup for skills, and the
  deleteUserResourceCoverage guard test enforces every ResourceType has
  a documented handler — wired in db.deleteUserSkills(user._id) and
  added the entry to HANDLED_RESOURCE_TYPES.
- Express 5's path-to-regexp v6 rejects the legacy `(*)` named-group
  glob syntax. The two skill file routes now use a plain `:relativePath`
  param; the client already encodeURIComponents the path, so a single
  param is sufficient and decoded server-side.

* 🪡 fix: Make Skill Name Uniqueness Application-Level

Resolve three more CI failures from the Skills scaffolding PR:

- Mongoose creates indexes asynchronously and mongodb-memory-server
  tests can race ahead of the unique (name, author, tenantId) index
  being built, so the duplicate-name uniqueness test was flaky.
  Added an explicit findOne pre-check inside createSkill that throws
  with code 11000 (mimicking the index violation), giving deterministic
  behavior. The unique index stays as the persistent guarantee.
- The deleteUser.spec.js and UserController.spec.js suites mock the
  ~/models module directly and were missing deleteUserSkills, causing
  deleteUserController to throw and return 500 instead of 200.
- Removed two doc-comment claims that the SKILL_NAME_MAX_LENGTH and
  SKILL_DESCRIPTION_MAX_LENGTH constants "match Anthropic's API". The
  values themselves are reasonable but the comments were misleading
  about who enforces them.

* 🪢 fix: Address Code Review Findings on Skills Scaffolding

Resolve all 15 findings from the comprehensive PR review:

Critical:
- Rollback the created skill when grantPermission throws so a transient
  ACL failure cannot leave an orphaned, inaccessible skill in the DB.
- Fix infinite query cache corruption in useUpdateSkillMutation helpers.
  setQueriesData([QueryKeys.skills]) matches useSkillsInfiniteQuery's
  InfiniteData cache entries, which have { pages, pageParams } shape —
  spreading data.skills on those would throw. Added an isInfiniteSkillData
  guard and per-page transform so both flat and infinite caches update
  correctly.

Major:
- Fix TUpdateSkillContext type: the public type declared previousListData
  but onMutate actually returns previousListSnapshots (a [key, value]
  tuple array). Updated the type + added TSkillCacheEntry as a shared
  export from data-provider.
- Add cancelQueries calls before optimistic update in onMutate so
  in-flight refetches cannot clobber the optimistic state.
- Parallelize deleteUserSkills ACL removal via Promise.allSettled instead
  of a sequential await loop — O(1) round-trip vs O(n).
- Stub mockDeleteUserSkills in stubDeletionMocks() and assert it's called
  with user.id in the deleteUser.spec.js happy-path test.
- Add idResolver: getSkillById to the SKILL branch in accessPermissions.js
  so GET /api/permissions/skill/<missing-id> returns 404 instead of 403.

Minor:
- Reuse resolved skill from req.resourceAccess.resourceInfo in getHandler
  to eliminate a redundant getSkillById call per GET /api/skills/:id.
- Reject PATCH /api/skills/:id requests whose body contains only
  expectedVersion — previously they silently bumped version with no
  changes, triggering spurious 409s for collaborators.
- Make TSkill.frontmatter optional (wire type) and add serializeFrontmatter
  / serializeSourceMetadata helpers that return undefined for empty
  objects instead of casting incomplete data to SkillFrontmatter.
- Standardize deleteUserSkills to accept string | ObjectId and convert
  internally, matching deleteUserPrompts's signature; UserController now
  passes user.id consistently.
- Replace bumpSkillVersionAndRecount (read-then-write, racy) with
  bumpSkillVersionAndAdjustFileCount using atomic $inc. upsertSkillFile
  pre-checks existence to distinguish insert (+1) from replace (0).
- Add DELETE /api/skills/:id/files/:relativePath integration tests
  covering success, 404, and 403 paths.

Nits:
- Drop trivial resolveSkillId wrapper — pass getSkillById directly.
- Remove dead staleTime: 1000 * 10 from useListSkillsQuery since all
  refetch triggers are already disabled.

* 🧭 fix: Resolve Second Skills Review Pass — Cache, Gate, TOCTOU

Address 13 of 14 findings from the second code review; reject #13 as
misread of the AGENTS.md import-order rule (package types correctly
precede local types regardless of length).

Major:
- Fix addSkillToCachedLists closure bug: a hoisted `prepended` flag
  was shared across every cache entry matched by setQueriesData, so
  concurrent flat + infinite caches would silently drop the prepend
  on whichever was processed second. Replaced the shared helper with
  three per-entry inline updaters that handle InfiniteData at the
  page level (page 0 only for prepend, all pages for replace/remove).
- Tighten patchHandler's expectedVersion validation: NaN passes
  `typeof === 'number'` and would previously leak current skill state
  via a misleading 409. Now requires finite positive integer and
  returns 400 otherwise.
- Guard decodeURIComponent in deleteFileHandler with try/catch —
  malformed percent encoding now returns 400 instead of 500.
- Add PermissionTypes.SKILLS + skillPermissionsSchema +
  TSkillPermissions in data-provider; seed default SKILLS permissions
  for ADMIN (all true) and USER (use + create only); wire
  checkSkillAccess / checkSkillCreate via generateCheckAccess onto
  the skills router mirroring the prompts pattern. Skills route now
  enforces role-based capability gates alongside per-resource ACLs.
  Test suite adds a mocked getRoleByName returning permissive SKILLS.
- Fix upsertSkillFile TOCTOU: replaced the pre-check + upsert pair
  with a single `findOneAndUpdate({ new: false, upsert: true })` call
  that atomically returns the pre-update doc (null ⇒ insert) so
  fileCount delta can't double-count on concurrent same-path uploads.

Minor:
- Add `sourceMetadata` to listSkillsByAccess .select() so summaries
  no longer silently drop the field for GitHub/Notion-synced skills.
- Include `cursor` in useListSkillsQuery's query key so manual
  pagination doesn't alias across pages.
- Clean up TSkillSummary to `Omit<TSkill, 'body' | 'frontmatter'>`
  matching what serializeSkillSummary actually emits; drop the
  Omit-then-re-add noise.
- Skip getPublicSkillIdSet in createHandler; a newly-created skill
  cannot have a PUBLIC ACL entry, so pass an empty set directly
  instead of paying a DB round-trip.
- Trim SkillMethods public surface: drop internal helpers
  countSkillFiles / deleteSkillFilesBySkillId / getSkillFile from the
  return object; inline the file cascade into deleteSkill.
- Use TSkillConflictResponse at the PATCH 409 call site instead of
  an inline ad-hoc object literal.
- Drop the now-unused EXPECTED_VERSION_ERROR module constant.

* 🧩 fix: Extend Role Schema + Types with SKILLS PermissionType

CI type-check and unit test failures from the PermissionTypes.SKILLS
addition surfaced three unrelated places that all hardcode the
permission-type set:

- IRole.permissions in data-schemas/types/role.ts enumerates every
  PermissionTypes key as an optional field. Adding SKILLS to the enum
  without updating the interface caused TS7053 'expression of type
  PermissionTypes can't be used to index type' errors in
  role.methods.spec.ts (lines 407-408, 477-478) because
  Object.values(PermissionTypes) now yielded a value the interface
  didn't cover.
- schema/role.ts rolePermissionsSchema mirrors the interface at the
  Mongoose layer; also needed SKILLS added so the persisted role
  document can actually store skill permissions.
- data-provider/roles.spec.ts has a guard test that every permission
  type carrying CREATE/SHARE/SHARE_PUBLIC must be explicitly "tracked"
  either in RESOURCE_PERMISSION_TYPES or in the PROMPTS/AGENTS/MEMORIES
  exemption list. Added SKILLS to the exemption list since skills
  follow the same default model as prompts/agents (USE + CREATE on for
  USER, SHARE / SHARE_PUBLIC off).

All three are additive pass-throughs with no behavior change.

* 🏷️ refactor: Introduce ISkillSummary for Narrow List Projection

Follow-up NITs from the second review pass on the Skills PR:

- Define ISkillSummary = Omit<ISkill, 'body' | 'frontmatter'> and use
  it as the element type in ListSkillsByAccessResult. The list query's
  .select() intentionally omits body and frontmatter for payload size,
  but the previous type claimed both fields were present — a type lie
  that would mislead future readers even though serializeSkillSummary
  never touches those fields at runtime. handlers.ts's signature for
  serializeSkillSummary now accepts ISkillSummary too.
- Document the intentional second-round-trip `findOne` in
  upsertSkillFile. Switching to `findOneAndUpdate({ new: false })`
  was required for TOCTOU-safe insert-vs-replace detection, which
  means the handler needs a follow-up query to return the post-upsert
  document. A comment now explains the tradeoff so future readers
  don't silently "optimize" it away.

No behavior change.

* 🌐 fix: Wire SKILL into SHARE_PUBLIC Resource Maps

Address codex comment #1 — making a skill public was blocked on two
hardcoded resource→permission-type maps that didn't know about SKILL:

- api/server/middleware/checkSharePublicAccess.js's
  resourceToPermissionType map was missing ResourceType.SKILL, so
  PUT /api/permissions/skill/:id with { public: true } would fall
  through to the 400 "Unsupported resource type for public sharing"
  path even though PermissionTypes.SKILLS exists and ADMIN has
  SHARE_PUBLIC configured. Added the mapping.
- client/src/hooks/Sharing/useCanSharePublic.ts has an identical
  client-side map used to gate the "Make Public" UI toggle. Without
  the SKILL mapping the hook returned false for everyone, so the
  toggle wouldn't render for skills once the sharing UI lands in
  phase 2. Added the mapping.

Codex comment #2 (create/update cache writes inject skills into
unrelated filtered lists) is invalid — it flags a pattern that
mirrors useUpdatePromptGroup (which the PR description explicitly
cites as the model) and is a deliberate optimistic-update tradeoff.
Trying to match each cache key's embedded filter would couple the
mutation callback to query-key internals, which is exactly what
setQueriesData is designed to avoid. No change there.

* 🧪 feat: Frontmatter Validation, Reserved-Name Fixes, Coaching Warnings

Address the follow-up review notes on the Skills PR. This commit closes
the gap between the wire-type promise and what the backend actually
enforces, tightens the reserved-name rules, and adds a non-blocking
coaching tier for validators.

Frontmatter validation (new):
- Add `validateSkillFrontmatter` in data-schemas/methods/skill.ts with
  strict mode — unknown keys are rejected so expanding the allowed set
  is an intentional code change. Known keys are type-checked against a
  `FrontmatterKind` table derived from Anthropic's Agent Skills spec
  (name, description, when-to-use, allowed-tools, arguments,
  argument-hint, user-invocable, disable-model-invocation, model,
  effort, context, agent, paths, shell, hooks, version, metadata).
- `hooks` and `metadata` get a shallow JSON-safety check (max depth 4,
  max string 2000, max array 100) instead of a full schema, since their
  full shapes live outside this module.
- Wired into BOTH createSkill AND updateSkill so the PATCH path can't
  smuggle invalid frontmatter past the validator.

Validation warning tier (new):
- Add optional `severity: 'error' | 'warning'` to `ValidationIssue`
  (defaults to error). `partitionIssues` splits an issue list into
  blocking errors and non-blocking warnings.
- `createSkill` / `updateSkill` filter on errors for the throw check
  and return warnings in a new `warnings: ValidationIssue[]` field on
  their result objects (`CreateSkillResult` / `UpdateSkillResult`).
- `validateSkillDescription` now emits a `TOO_SHORT` warning for
  descriptions under 20 chars — the primary triggering field, so a
  little coaching goes a long way.
- `createHandler` / `patchHandler` in packages/api surface the warnings
  via a new `attachWarnings` helper that decorates the serialized
  response with a `warnings?: TSkillWarning[]` field.
- `TSkill` gains an optional `warnings?: TSkillWarning[]` field
  documented as "present on POST/PATCH, never on GET".

Reserved-name filter (tightened):
- Replace the substring match (`.includes('anthropic')`) with prefix
  matching on `anthropic-` and `claude-` plus exact-match rejection of
  CLI slash-command collisions (help, clear, compact, model, exit,
  quit, settings, plus the bare `anthropic` / `claude` words). Both
  the pure validator (`methods/skill.ts`) and the Mongoose schema
  validator (`schema/skill.ts`) updated in lockstep; comments on
  each reference the other to prevent drift.
- `research-anthropic-helper` and `about-claude` are now allowed;
  `anthropic-helper`, `claude-bot`, and `settings` are still rejected.

Documentation:
- Add docstrings on `ISkill`, `schema/skill.ts`, and `TSkill` explaining
  the semantics of `name` (Claude-visible identifier, kebab-case,
  stable), `displayTitle` (UI-only cosmetic label, NOT sent to Claude),
  `description` (highest-leverage trigger field), and `source` /
  `sourceMetadata` (reserved for phase 2+ external sync).
- Add a detailed consistency comment on `bumpSkillVersionAndAdjustFileCount`
  explaining that it runs as a separate MongoDB operation from
  upsertSkillFile/deleteSkillFile, so `fileCount` can drift if the
  second op fails — options listed, tradeoff documented, phase 1
  risk window noted as closed because upload is still stubbed.

Tests:
- data-schemas skill.spec.ts: destructure `{ skill, warnings }` from
  createSkill at every call site; add a TOO_SHORT warning test, a
  frontmatter strict-mode test, reserved-prefix tests (including
  positive cases for substring names that should pass), CLI reserved
  word tests, and a full `validateSkillFrontmatter` describe block
  covering unknown keys, type mismatches, and deep-nesting rejection.
- api/server/routes/skills.test.js: bump default test description
  above the 20-char threshold, add a warning-emission test, add
  reserved-prefix + reserved-CLI-word tests, add an unknown-frontmatter-
  key test asserting the 400 response carries `issues` with `UNKNOWN_KEY`.

* 📦 fix: Export CreateSkillResult from data-schemas Methods Index

`CreateSkillResult` was defined in `methods/skill.ts` and consumed by
`packages/api/src/skills/handlers.ts` but never re-exported from the
methods barrel, so the type-check job failed with TS2724
"'@librechat/data-schemas' has no exported member named 'CreateSkillResult'".

Rollup's bundle-mode build picked up the type via its internal resolver,
but the standalone `tsc --noEmit` type-check ran against the package's
public entrypoint and couldn't see it. Added the type import + export
alongside the existing `UpdateSkillResult` export, which fixes the
CI type-check without any runtime change.

🛡️ fix: Prevent silent crash from unhandled MCP OAuth reconnect rejections (#12812)
* 🛡️ fix: Install global `unhandledRejection` handler

Node 15+ terminates the process by default when a promise rejection goes
unhandled. Under MCP OAuth reconnect storms and streamable-HTTP transport
resets, fire-and-forget async paths can emit transient rejections (ECONNRESET,
token refresh races) that would otherwise silently kill the server — no
uncaught exception log, no OOM signal. Register a listener so these paths log
and the process keeps serving other requests.

Refs: #12078

* 🔧 fix: Guard MCP OAuth reconnect fire-and-forget calls

`OAuthReconnectionManager.tryReconnect` awaits `getServerConfig` outside its
inner try/catch, so a rejection from the registry (or any throw before the
guarded block) would escape the fire-and-forget `void` call sites and
propagate as an unhandled rejection — the failure mode behind the silent
crashes reported in #12078. Route both call sites through a `safeTryReconnect`
wrapper that attaches a terminal `.catch` so unexpected rejections are
surfaced via the logger instead.

Refs: #12078

* 🧹 fix: Address review findings on MCP OAuth reconnect crash fix

- Move `getServerConfig` inside `tryReconnect`'s try/catch so the registry
  rejection path is handled by the inner cleanup (the structural root cause
  behind the silent crash). The outer `safeTryReconnect` wrapper remains as
  defense-in-depth.
- Extract the failed-reconnect cleanup as a private `cleanupOnFailedReconnect`
  method and invoke it from `safeTryReconnect`'s catch as well, so any
  rejection that does escape the inner try (e.g. a future regression) still
  resets tracker state instead of leaving the server stuck in `active` for
  the full `RECONNECTION_TIMEOUT_MS` window.
- Update the regression test to assert tracker state is cleaned up
  (`isActive` cleared, `isFailed` set, `disconnectUserConnection` called) so
  it can detect the stale-state failure mode it was meant to guard against.
- Forward non-Error rejection reasons as-is in the global handler so
  structured payloads like `{ code: "ECONNRESET", errno: -104 }` survive
  instead of being collapsed to "[object Object]" by `String()`.

Refs: #12078, review of #12812

* 🚑 fix: Restore fail-fast on boot rejection in primary server entry

`startServer()` was invoked bare in `api/server/index.js`. Before installing
the global `unhandledRejection` handler, a startup rejection (`connectDb`,
`getAppConfig`, `performStartupChecks`) terminated the process via Node's
default — Kubernetes / the orchestrator restarted the pod immediately.

After the handler was added, the same rejection was caught and logged, then
the process kept running half-initialized (no HTTP listener) until the
liveness probe eventually timed out — slow, indirect recovery instead of a
fast restart.

Wrap `startServer()` with the same `.catch(() => process.exit(1))` pattern
already used in `experimental.js` so boot failures fail-fast.

Refs: #12078, codex review of #12812

* 🚑 fix: Fail-fast on post-listen init failure in both server entries

The `app.listen` callback in `index.js` and `experimental.js` is async and
awaits `initializeMCPs`, `initializeOAuthReconnectManager`, and
`checkMigrations`. The callback's promise is detached from
`startServer().catch(...)` (the outer catch only sees errors that occurred
before `app.listen` was called), so without explicit handling those init
rejections used to terminate the process via Node's default and now would
be swallowed by the new `unhandledRejection` handler — leaving the HTTP
server listening (and passing liveness probes) while MCP / OAuth / migration
state is broken.

Wrap the post-listen init block in a try/catch that logs and calls
`process.exit(1)` so initialization failures stay fail-fast.

🗨️ fix: Preserve ModelSpec Preset greeting and iconURL Through Config Parse (#12809)
`tModelSpecPresetSchema` was omitting `greeting` and `iconURL`, so
`configSchema.strict().safeParse()` stripped these admin-configured
fields from `modelSpecs.list[].preset` before the server sent the
startup config to the client — breaking the landing greeting and the
`preset.iconURL` fallback in `getModelSpecIconURL`.

Keep `spec` and `presetOverride` omitted (those are truly
client-managed), and flip the schema test to assert `greeting`/`iconURL`
are preserved.

🔐 fix: Restore Tenant Context in MCP OAuth Callback (#12782)
* fix: restore tenant context in MCP OAuth callback for multi-tenant deployments

The MCP OAuth callback is a cross-origin redirect from the OAuth
provider. SameSite=Strict cookies (including the JWT) are not sent,
leaving the callback with no tenant context. With
TENANT_ISOLATION_STRICT=true, all DB writes fail.

Stores tenantId in flow metadata at OAuth initiation time (when
the user is authenticated), then restores it via tenantStorage.run
in the callback, wrapping the entire post-validation body.

🧹 fix: Clean Up Orphaned Agent File Stubs After Deletion (#12781)
* 🧹 fix: Prune Orphaned File References on File Deletion

Deleting a file via the Manage Files tab left its file_id in every agent's
tool_resources.*.file_ids. Stubs accumulate until the frontend dedupe keys
them as duplicates and blocks all new uploads (issue #12776).

- Add removeAgentResourceFilesFromAllAgents in packages/data-schemas: a
  single updateMany/$pullAll across every EToolResources category.
- Invoke it from processDeleteRequest after db.deleteFiles so every
  referencing agent is cleaned up, not just the one passed in req.body.
- Wrap the cleanup in try/catch so a stale agent update cannot mask a
  successful file deletion.

* 🧼 fix: Prune Orphaned File References on Agent Update

Already-affected agents would stay broken even after the delete-time fix:
the stubs sit on the agent document until something strips them. Heal them
on the next save (issue #12776).

- Add collectToolResourceFileIds + stripFileIdsFromToolResources helpers
  in @librechat/api — centralizing the tool_resources traversal used by
  the controller and the follow-up migration script.
- In updateAgentHandler, check the effective tool_resources against the
  files collection. When orphans are found, either strip them from the
  incoming tool_resources (if the update sets them) or run the bulk
  cleanup (if the update leaves tool_resources untouched).

* 🧰 chore: Add Migration to Clean Up Orphaned Agent File References

Complements the delete-time and save-time fixes by healing agents that
already accumulated orphan stubs before the upgrade (issue #12776). The
script is idempotent — re-running it on a clean database is a no-op.

- Add config/migrate-orphaned-agent-files.js following the existing
  migrate-*.js convention: --dry-run by default omitted (writes by
  default) and --batch-size= tuning knob. Streams agents via cursor.
- Register migrate:orphaned-agent-files and :dry-run npm scripts.
- Reuse collectToolResourceFileIds from @librechat/api so migration and
  runtime share the same traversal logic.

* 🩹 fix: Address Codex/Copilot Review on Orphaned Agent File Cleanup

Refines the #12776 fix series based on automated review feedback.

- Scope save-time pruning to the current agent only. When a PATCH
  carries tool_resources, strip orphans from the incoming payload and
  pay the DB round-trip only then. Removes the collection-wide
  updateMany previously triggered when tool_resources was absent
  (Codex P2 / Copilot).
- Wrap the orphan check in try/catch so a transient db.getFiles
  failure can't turn a good save into a 500 (comprehensive review #1).
- Replace Object.values(EToolResources) casts with an explicit list of
  agent-side categories in both orphans.ts and agent.ts. code_interpreter
  belongs to the Assistants API and isn't a key of AgentToolResources —
  including it was a type lie and generated dead MongoDB clauses
  (comprehensive review #3, #8).
- Export TOOL_RESOURCE_KEYS from @librechat/api and consume it in the
  migration script, dropping one duplicated definition (#4).
- Cap migration results.details at 50 sample entries so the memory
  footprint stays bounded on deployments with thousands of corrupted
  agents (Codex P3).
- Add migrate:orphaned-agent-files:batch npm script to match the
  convention set by migrate-agent-permissions / migrate-prompt-permissions
  (#7).
- Add controller-level tests covering the three orphan-pruning paths:
  strip from incoming tool_resources, leave alone when tool_resources
  is absent, swallow db.getFiles errors and still save (#6).
- Back pre-existing "should validate tool_resources in updates" test's
  file_ids with real File docs — the new pruning would otherwise strip
  them, and that test is about OCR conversion / schema filtering, not
  file existence. Register the File model in beforeAll so the fixture
  works.

* 🩹 fix: Tighten TOOL_RESOURCE_KEYS Type and Align Migration Sample Output

Two follow-ups from the second review pass.

- Type data-schemas' TOOL_RESOURCE_KEYS as ReadonlyArray<keyof
  AgentToolResources> instead of readonly string[]. Data-schemas depends
  on data-provider, so the import is clean. Catches typos and aligns
  with the matching export in @librechat/api — doesn't guarantee
  exhaustiveness, but that's a TypeScript limitation, not a workspace
  one.
- Align the migration's console output with DETAIL_SAMPLE_LIMIT: print
  every collected detail (up to 50) and, when more agents were affected
  than the sample size allowed, show a truncation notice. The old hard
  cap of 25 meant affected agents in the 26-50 range were collected
  but never shown.

*  test: Add Integration Coverage for Orphan Cleanup Paths (#12776)

Exercise the delete-time and migration paths end-to-end against a real
in-memory Mongo. Catches integration bugs the isolated unit tests on
each layer couldn't.

- api/server/services/Files/process.integration.spec.js — the primary
  repro: seed an Agent + File, call processDeleteRequest, assert the
  file_id disappears from every referencing agent's tool_resources
  while unrelated agents stay untouched. Also covers the no-op case
  and confirms a failure in the new cleanup step cannot roll back the
  file deletion itself.
- api/test/migrate-orphaned-agent-files.spec.js — drives the migration
  module: --dry-run reports without writing, apply mode prunes across
  every tool_resource category, re-running is idempotent, and
  DETAIL_SAMPLE_LIMIT caps the in-memory sample on wide corruption.
  Mocks only the connect helper (the spec owns the mongoose instance)
  so the real migration code path — cursor, $pullAll, reduce — runs.

* 🔒 fix: Run Orphan Cleanup Migration in System Tenant Context

Codex P2 catch: under TENANT_ISOLATION_STRICT=true, the migration
throws on the very first Agent.countDocuments() because the tenant
isolation plugin fail-closes on queries without tenant context — which
makes migrate:orphaned-agent-files unusable on the exact deployments
most likely to have accumulated corruption.

- Wrap the scan/prune body in runAsSystem so queries bypass the tenant
  filter (SYSTEM_TENANT_ID sentinel). The migration legitimately needs
  cross-tenant visibility — this is the same pattern seedDatabase and
  the S3 refresh job already use.
- Add a regression test that spies on Agent.countDocuments() and
  asserts the active tenantStorage context is SYSTEM_TENANT_ID during
  the call. Pins the wrap against future regressions without the
  brittleness of toggling the strict-mode env var (which caches on
  first read).

Note: the delete-time and save-time paths already run inside an
authenticated HTTP request where tenantStorage.run is set by auth
middleware, so the cleanup naturally scopes to the current tenant —
which is the correct behavior there since file ownership is
tenant-scoped.

* 🧹 chore: Drop Unused path Import From Process Integration Spec

Leftover from an earlier iteration that resolved the migration path
via path.resolve before I switched to a relative require. The import
does nothing now — removing it.

🔐 fix: Prefer WWW-Authenticate resource_metadata Hint for MCP OAuth (#12763)
* 📦 chore: Bump @modelcontextprotocol/sdk to v1.29.0

* ♻️ refactor: Extract WWW-Authenticate Probe Helper for MCP OAuth

* 🔐 fix: Prefer WWW-Authenticate resource_metadata Hint for MCP OAuth

Per RFC 9728 §5.1, the `resource_metadata=<url>` parameter in a 401
`WWW-Authenticate: Bearer` challenge is the authoritative protected-resource
metadata source. Path-aware `.well-known` discovery was winning over the
hint, so split deployments that serve valid-but-wrong metadata at the
path-aware endpoint stranded OAuth at defunct authorization servers.

Threads the hint through `discoverOAuthProtectedResourceMetadata` via
`opts.resourceMetadataUrl` in both startup detection and the OAuth handler,
matching the behavior of Claude Desktop, the MCP Inspector, OpenAI tooling,
and Microsoft Copilot Studio.

Fixes #12761.

* 🧵 fix: Thread OAuth-Aware fetchFn Through Resource-Metadata Probe

Without this, admin-configured `oauthHeaders` (e.g. a gateway API key that
fronts the MCP endpoint) were stripped from the probe, causing the gateway
to 401 for the wrong reason and masking the real `WWW-Authenticate` hint.

The helper now accepts a FetchLike and defaults to global fetch, so the
startup detection path is unchanged while the handler passes its OAuth-
aware wrapper through.

* 🧹 refactor: Address MCP OAuth Probe Review Findings

- Thread `fetchFn` through `probeResourceMetadataHint` so admin-configured
  `oauthHeaders` reach the probe (a gateway API key that fronts the MCP
  endpoint would otherwise 401 us for the wrong reason and hide the real
  Bearer challenge).
- Skip the redundant HEAD request in `checkAuthErrorFallback` when the
  probe already observed a 401/403; fall back to a fresh HEAD only when
  every probe attempt threw (transient network error).
- Narrow the oauth barrel: drop `export * from './resourceHint'` so the
  helper stays an internal module.
- Add `scope` extraction coverage (`Bearer scope="read write"`) and a
  403-only observation path; isolate `MCP_OAUTH_ON_AUTH_ERROR=true` in a
  dedicated suite so precise-outcome tests aren't muddied by the safety net.

*  fix: Use Zod Schema in MCP Reconnection-Storm Test Tool

MCP SDK 1.28 tightened `McpServer.tool()` to require Zod schemas instead
of plain JSON-Schema objects. Swap the `{ message: { type: 'string' } }`
shape for `z.string()` so the fixture server spins up under SDK 1.29.

* 🛡️ fix: Harden MCP OAuth resource_metadata Hint Against SSRF

The `resource_metadata` URL is echoed from an untrusted MCP server, so
handing it straight to the SDK lets a malicious server redirect discovery
at private IPs, the cloud metadata service, or any host the admin did not
intend to reach. Caught by the Copilot review on #12763.

- `handler.ts`: run the hint through the same `validateOAuthUrl` /
  `allowedDomains` gate that already guards the authorization-server URL;
  drop it and fall back to path-aware discovery on rejection.
- `detectOAuth.ts`: no admin-scoped allowedDomains here, so apply a
  strict `isSSRFTarget` + DNS resolution check and silently discard any
  hint pointing at a private/loopback/metadata address.
- Tests cover both the hostname-list and DNS-resolution rejection paths
  and assert the SDK falls back to path-aware discovery unharmed.

* 🧪 test: Mock ~/auth in fallback Suite for Consistency

Matches the main `detectOAuth.test.ts` mock so the SSRF guards added in the
previous commit don't touch the real `~/auth` module at test time.

* 🔍 fix: Scope OAuth Fallback to HEAD + Parse Multi-Scheme WWW-Authenticate

Two codex findings on #12763:

- **P1**: the merged `authChallenge` flag was letting POST-only 401/403 flip
  the `MCP_OAUTH_ON_AUTH_ERROR` fallback, misclassifying WAF/CSRF-hardened
  endpoints (HEAD 200 + POST 403) as OAuth-required. Rename to
  `headAuthChallenge` and derive it only from the HEAD probe, matching the
  legacy fallback's HEAD-only semantics. Add a regression test.
- **P2**: the SDK's `extractWWWAuthenticateParams` only inspects the first
  scheme token, so multi-scheme headers like
  `Basic realm="api", Bearer resource_metadata="..."` silently dropped the
  authoritative Bearer hint. Fall back to a regex across the full header
  when the SDK returns nothing but Bearer is present. Add a regression
  test covering the multi-scheme case.

* 🧽 refactor: Tighten MCP OAuth Probe Semantics

Addresses the second external review pass plus codex P2:

- Merge the two stacked JSDoc blocks on `probeResourceMetadataHint` into one
  with a proper `@returns` section.
- Only short-circuit HEAD when it delivered the `resource_metadata` hint
  itself — a Bearer-without-params HEAD now lets POST run, since some
  servers surface their hint only on POST and we were missing it.
- Drop the unused `scope` field from `ResourceHintProbeResult`; no caller
  read it, and YAGNI beats a reserved field.
- Remove the redundant `OAUTH_ON_AUTH_ERROR` guard inside
  `checkAuthErrorFallback` — the only call site already gates on it.
- Codex P2: signal "HEAD status unknown" via `null` when the HEAD probe
  threw and POST returned non-auth. Previously that combination leaked a
  `{headAuthChallenge: false}` result and silently skipped the fallback's

  transient HEAD failure.

Regression tests cover every path: Bearer-no-hint-on-HEAD + hint-on-POST,
multi-scheme `Basic + Bearer` headers, HEAD-threw + POST-200 retry, and
the WAF/CSRF-only POST 403 case.

- Move `bearerChallenge` computation after the `!wwwAuth` guard so the

  early-return path is now a clean unconditional exit.
- Add a regression test that asserts `Bearer resource_metadata="not-a-url"`
  yields `resourceMetadataUrl: undefined` without throwing, locking in
  the try/catch safety net in `extractHintFromHeader` and the SDK
  parser alike.

🔒 fix: Validate MCP OAuth Protected Resource Metadata binding (#12755)
* 🔒 fix: Validate MCP OAuth Protected Resource Metadata binding (GHSA-gvpj-vm2f-2m23)

RFC 9728 §3.3/§7.3 requires clients to verify that the `resource` identifier
advertised by an OAuth Protected Resource Metadata document matches the URL
used to fetch it. Without this check, a malicious MCP server can serve
metadata pointing at a legitimate server's `authorization_servers`, causing
LibreChat to obtain an access token for the real server and send it to the
attacker in subsequent API calls.

Validation happens at discovery time so the entire metadata document is
discarded on mismatch — `authorization_servers` on a spoofed document is
equally untrustworthy and is the primary theft vector in the PoC.

Uses the MCP SDK's own `checkResourceAllowed` (origin + path-prefix) for
semantic parity with `selectResourceURL`, a SDK code path LibreChat bypasses.
This is looser than RFC-strict equality (handles common cases like
`/mcp/sse` server vs `/mcp` advertised resource, or trailing-slash
normalization) while still rejecting cross-origin spoofs and same-origin
sibling-path confusion.

* 🛡️ fix: Re-validate Resource Binding at MCP OAuth Token Exchange

Adds a defense-in-depth re-assertion of the RFC 9728 §3.3 resource/server
binding inside `completeOAuthFlow`. Flows have a 10-minute TTL, so a flow
initiated under pre-fix (vulnerable) code could still be in-flight at upgrade
time carrying unvalidated resource metadata. Re-checking here closes that
window without requiring operators to flush flow state on deploy.

Also guards against future regressions that might re-introduce unvalidated
paths into the flow-metadata pipeline (GHSA-gvpj-vm2f-2m23).

*  test: Address Review Findings on MCP OAuth Resource Validation

Follow-up to GHSA-gvpj-vm2f-2m23 fix. Resolves three reviewer findings:

- Assert `failFlow` is called when `completeOAuthFlow` rejects at
  re-validation — locks in the "no stuck PENDING entry" guarantee that the
  catch block already provides in production code.
- Update the "no resource metadata" warning in `initiateOAuthFlow`: post-fix,
  that branch is only reachable when PRM discovery returned nothing (404,
  network error, server without RFC 9728). A document with a missing
  `resource` field now throws earlier in `assertResourceBoundToServer`, so
  the old "missing 'resource' property" phrasing described a case that can
  no longer reach this branch.
- Add a test for an unparseable `resource` string triggering the
  error-wrapping path in `assertResourceBoundToServer` (verifies the wrapper
  surfaces a descriptive message instead of leaking a raw `TypeError:
  Invalid URL` from the SDK's `new URL()` call).

🗺️ fix: Resolve Custom-Endpoint Providers for Summarization (#12739)
* 🔧 fix: resolve custom-endpoint providers for summarization

When `summarization.provider` in `librechat.yaml` is set to a custom-endpoint
name (e.g. `Ollama`), the string was passed verbatim to the agents SDK, which
only knows a fixed set of provider names and threw
`Unsupported LLM provider: Ollama`.

Before shaping the summarization config for the SDK, resolve the provider
through `getProviderConfig`: custom-endpoint labels are remapped to the
underlying SDK provider (e.g. `openAI`) and the endpoint's baseURL/apiKey are
injected into `parameters` so the summarization model reaches the right
backend, even when summarization targets a different custom endpoint than the
main agent.

Unknown names and names that appear with no matching endpoint flow through
unchanged so the SDK can surface a clear error. User-provided credentials and
unresolved env-var references are skipped rather than forwarded, letting the
SDK's self-summarize path reuse the agent's own clientOptions.

Ref: LibreChat Discussion #12614

* address: widen unresolved-env-var guard, fix test naming

- Reject summarization overrides when the extracted baseURL/apiKey still
  contains any `${...}` placeholder, including prefix/suffix patterns like
  `https://${UNSET}.example.com` that `envVarRegex` (exact-match) missed.
- Rename the "case-insensitive" test to reflect that only `Ollama` is
  normalized via `normalizeEndpointName`; add coverage proving other
  custom-endpoint names match case-sensitively.

* address: use req.config in responses.js; forward full endpoint options

- `responses.js` relied on a module-level `appConfig` set via `setAppConfig`,
  which is never called anywhere. Use `req.config` directly so the
  summarization provider resolver actually runs on the responses route.
- Route the custom endpoint config through `getOpenAIConfig` so summarization
  inherits the same `headers`, `defaultQuery`, `addParams`/`dropParams`, and
  `customParams` transforms (Anthropic/Google/etc.) that `initializeCustom`
  applies for the main agent flow. Strip the stale `model`/`modelName`
  defaults so `summarization.model` still wins.

* address: skip overrides when summarization matches agent endpoint

When `summarization.provider` resolves to the same custom endpoint as the
main agent, rely on the SDK's self-summarize path (which reuses
`agentContext.clientOptions` unchanged) rather than injecting overrides.
Otherwise the shallow spread of `clientOverrides.configuration` would
replace the agent's request-resolved state (dynamic headers, proxy/fetch
options) with yaml-only config.

Only applies when summarization targets a *different* endpoint from the
agent; the yaml config is all we have in that case, so overrides still
flow through.

* address: preserve raw provider when overrides cannot be built

When summarization points at a different custom endpoint than the agent
and we can't resolve the endpoint's credentials (user_provided, or a
still-unresolved `${VAR}` after env extraction), remapping to `openAI`
without overrides would silently route summaries to the default OpenAI
client. Preserve the raw provider name so the SDK raises a clear
"Unsupported LLM provider" error (now also logged, via the agents SDK
defense-in-depth fix) instead of sending traffic to the wrong backend.

* address: resolve endpoint headers and forward PROXY to summarization

- Custom-endpoint `headers` now flow through `resolveHeaders` before
  reaching `getOpenAIConfig`, matching the main agent path. This ensures
  templated values like `\${PORTKEY_API_KEY}` or `{{LIBRECHAT_BODY_...}}`
  are substituted for summarization requests instead of being forwarded
  literally.
- `PROXY` env var is now passed into `getOpenAIConfig` so cross-endpoint
  summarization honors outbound proxy dispatchers configured for the rest
  of the deployment.

* address: user summarization parameters win over endpoint defaults

Flip the merge order so `summarization.parameters` from yaml override
`clientOverrides` defaults (which come from `getOpenAIConfig` and always
include `streaming: true` etc.). A user who sets `parameters.streaming:
false` in their config should still see non-streaming summarization for
providers that require it.

* address: review feedback (logging, dead code, DRY, types, deep-merge)

- Log error in the resolveSummarizationProvider catch-all so programming
  bugs in getProviderConfig/getOpenAIConfig/resolveHeaders surface in
  operator logs instead of falling through silently.
- Drop dead `setAppConfig`/`appConfig` infrastructure in responses.js and
  fix adjacent `allowedProviders` reference that also relied on the
  never-initialized module-level appConfig. Uses `req.config` directly.
- Import canonical `normalizeEndpointName` from librechat-data-provider
  instead of duplicating it locally.
- Replace `SummarizationClientOverrides = Record<string, unknown>` with
  an explicit interface covering the known fields.
- Deep-merge `configuration` when user-supplied `summarization.parameters.
  configuration` overlaps the resolved endpoint configuration, so user
  additions (e.g. `defaultQuery`) don't wipe out `baseURL`/`defaultHeaders`.
- Wrap `process.env` mutations in test in `try/finally` so a failed
  assertion doesn't leak env state into subsequent tests.
- Drop `as unknown as AppConfig` in test helper; fixture now matches the
  `AppConfig` shape directly using a `Partial<TEndpoint>` union.
- Trim JSDoc that restated the name it was attached to.

* address: review nits — import order, local test type, conflict test

- Move `import { logger }` up into the package value-imports section so
  it no longer sits between `import type` blocks.
- Replace `as unknown as SummarizationConfig['parameters']` in the
  deep-merge test with a named `TestSummarizationParameters` type and a
  single narrowing cast at the call site, making intent explicit.
- Add a test proving that user-supplied `configuration.baseURL` wins
  over the resolved endpoint baseURL, locking in the deep-merge's
  user-wins-on-conflict semantics that the previous suite only exercised
  additively.

🤝 fix: Load Handoff Agents for Agents API (#12740)
* 🤝 fix: load handoff sub-agents on OpenAI-compat endpoints (#12726)

Extracts the BFS discovery + ACL-gated initialization of handoff sub-agents
into a shared `discoverConnectedAgents` helper in `@librechat/api` and
wires it into the OpenAI-compatible `/v1/chat/completions` and Open
Responses `/v1/responses` controllers. These endpoints previously only
passed the primary agent config to `createRun` while keeping
`primaryConfig.edges` intact, which forced `MultiAgentGraph` into
multi-agent mode without loading the referenced sub-agents and caused
StateGraph to throw "Found edge ending at unknown node <id>".

The discovery helper also filters orphaned edges (deleted sub-agents or
those the caller lacks VIEW permission on), so API users see the same
graceful fallback the chat UI already had.

* 🧪 fix: use ServerRequest in discovery spec helpers

CI `tsc --noEmit -p packages/api/tsconfig.json` caught that the test
helpers typed `req` as `express.Request`, which is not assignable to
`DiscoverConnectedAgentsParams.req` (typed as `ServerRequest` whose
`user` is `IUser`). Local jest passed because ts-jest is transpile-only,
but the CI typecheck uses the full compiler.

* 🪲 fix: drop orphan edges on both endpoints, not just `to`

Addresses the P1 codex finding on #12740: `filterOrphanedEdges`
previously only removed edges whose `to` referenced a skipped agent.
Edges whose `from` was a skipped agent — the symmetric case in a
bidirectional graph like `A <-> B` where `B` is deleted or the user
lacks VIEW on it — leaked through to `createRun` and re-triggered
`Found edge ending at unknown node <id>` at StateGraph compile time.

The filter now drops an edge if either endpoint references a skipped
id, and the existing `to`-only test cases were updated to reflect the
stricter behavior. Adds a bidirectional-graph regression test in
`discovery.spec.ts`.

* 🔒 fix: enforce REMOTE_AGENT ACL on handoff sub-agents for API routes

Addresses the second P1 codex finding on #12740: the OpenAI-compat
`/v1/chat/completions` and Open Responses `/v1/responses` routes gate
the primary agent on `REMOTE_AGENT` (via `createCheckRemoteAgentAccess`),
but `discoverConnectedAgents` was checking handoff sub-agents against
the looser in-app `AGENT` resource type. That allowed a remote caller
who could reach the orchestrator but had only in-app visibility on a
sub-agent to invoke it via the API — bypassing the remote-sharing
boundary.

Adds an optional `resourceType` param to `discoverConnectedAgents`
(defaulting to `AGENT` for the chat UI path) and passes
`ResourceType.REMOTE_AGENT` from both API controllers so every
discovered sub-agent clears the same sharing boundary enforced at
route entry.

* 🧯 fix: enforce allowedProviders for discovered sub-agents

Addresses the third P1 codex finding on #12740: `discoverConnectedAgents`
forwarded the caller's `endpointOption` verbatim into `initializeAgent`,
but on the OpenAI-compat routes that option's `endpoint` is the primary
agent's provider (e.g. `openai`), not `agents`. `initializeAgent` only
enforces `allowedProviders` when `isAgentsEndpoint(endpointOption.endpoint)`
is true, so handoff sub-agents silently bypassed the provider allowlist
configured under `endpoints.agents.allowedProviders`.

Override `endpointOption.endpoint` to `EModelEndpoint.agents` for every
per-sub-agent init call. The primary agent still uses the caller's
endpointOption as before — this only affects the BFS-loaded handoff
targets. Regression test asserts the override.

* ✂️ fix: prune unreachable sub-agents after orphan-edge filtering

Addresses the fourth P1 codex finding on #12740: BFS eagerly initializes
every sub-agent referenced in the primary's edge scan, but once
`filterOrphanedEdges` drops edges whose endpoints were skipped, some of
those sub-agents end up disconnected from the primary. In an `A -> B ->
C` graph (edges stored directly on A) where B is skipped (missing or
no VIEW), both edges are filtered, but C was already loaded and would
still be passed to `createRun` — which flips into multi-agent mode on
`agents.length > 1` and turns C into an unintended parallel start node.

After filtering edges, compute the set of agent ids reachable from the
primary through the surviving edge set and prune `agentConfigs` to that
set. Two regression tests added: one for the pruning case, one that
confirms agents connected via surviving edges are still kept.

* 🔁 fix: don't seed initialize.js agentConfigs from the pre-pruning callback

Addresses the fifth P1 codex finding on #12740: `onAgentInitialized`
fires during BFS, BEFORE the helper prunes agents that become
disconnected once `filterOrphanedEdges` runs. Writing the sub-agent
straight into the outer `agentConfigs` there and then only additively
merging the pruned `discoveredConfigs` left stranded entries in the
outer map, and `AgentClient` would still hand them to `createRun` as
extra parallel start nodes (the exact failure mode the pass-4 prune
was meant to eliminate for the API controllers).

Drop the `agentConfigs.set` from the callback and replace the additive
merge with a direct copy from `discoveredConfigs`, which is now the
single authoritative source of what the run should see. The
per-agent tool context map is still populated during BFS — stale
entries there are harmless because they're only read by closure inside
`ON_TOOL_EXECUTE` and are unreachable once the agent is not in
`agentConfigs`.

* 🔬 fix: address audit findings on discovery helper

Resolves findings from a comprehensive external audit of #12740.

**Finding 1 (CRITICAL) — stale edges survive the reachability prune.**
The pass-4 prune removed unreachable agents from `agentConfigs` but left
matching edges in the return value. In an `A -> B -> C -> D` graph (all
edges stored on A) where B is skipped, `filterOrphanedEdges` drops A->B
and B->C but keeps C->D (neither endpoint is skipped). The caller then
sees `agentConfigs` without C/D but `edges` still references them,
flipping `createRun` into multi-agent mode with mismatched agents/edges
— the exact crash this PR is supposed to fix. Now filter the edge list
to the reachable set in the same pass, so the returned shape is
self-consistent: every edge endpoint is either the primary id or a key
of `agentConfigs`. New regression test covers A->B->C->D with B skipped.

**Finding 2 (MAJOR) — unconditional `getModelsConfig` on every API
request.** The OpenAI-compat and Responses controllers called
`getModelsConfig(req)` and `discoverConnectedAgents` even when the
primary agent had no edges (the common single-agent API case). Gate
both behind `primaryConfig.edges?.length > 0` so single-agent runs
don't pay that cost.

**Finding 5 (MINOR) — silent mutation of caller's
`primaryConfig.userMCPAuthMap`.** The helper aliased that object and
then `Object.assign`'d sub-agent entries into it, changing the caller's
config in-place. Shallow-clone up front so the returned merged map is
the only destination.

**Finding 7 (NIT) — dead `?? []` coalescing.**
`filterOrphanedEdges` always returns a concrete array, so the
`discoveredEdges ?? []` fallback was never reached. Simplified the
`primaryConfig.edges = …` assignment.

Also adds a test that verifies `primaryConfig.userMCPAuthMap` is not
mutated in-place.

* 🧹 chore: address audit NITs on discovery helper

Addresses two NIT findings from the post-fix audit:

**F1** — the shallow clone on `primaryConfig.userMCPAuthMap` was only
applied on the primary side; the `else` branch (hit when the primary
had no MCP auth and the first sub-agent seeds the map) assigned the
sub-agent's `config.userMCPAuthMap` directly, so a later sub-agent's
`Object.assign` mutated the first one's map in place. Harmless in
practice (per-request ephemeral objects) but asymmetric. Clone in the
else branch too. Test added.

**F2** — `initialize.js` had a defensive `if (agentConfigs.size > 0 &&
!edges) edges = []` normalizer. Pre-existing dead code: the helper now
always returns a concrete array from `filteredEdges.filter(...)`.
Removed for clarity.

* 🕸 fix: require all sources reachable when traversing fan-in edges

Addresses the seventh P1 codex finding on #12740: the reachability BFS
advanced through an edge as soon as any of its `from` endpoints matched
the current frontier node (`sources.includes(current)`), but the
subsequent edge filter required ALL sources to be reachable (`every`).
The two-semantics mismatch let a fan-in edge like `{from: ['A','B'],
to: 'C'}` mark C reachable purely via A even when B had no path from
the primary, then drop the edge itself at filter time. Result: C
survived in `agentConfigs` with no surviving edge connecting it to A,
so `createRun` flipped into multi-agent mode on `agents.length > 1`
and C ran as an unintended parallel root.

Replace the BFS with a fixed-point iteration keyed on the same
all-sources-reachable predicate used by the filter, so traversal and
filtering stay aligned and multi-source edges only fire once every
source is in the reachable set.

Two regression tests added:
- `{from: ['A','B'], to: 'C'}` with B having no incoming path — asserts
  neither B nor C leak into the result.
- `A -> B`, `A -> C`, `['B','C'] -> D` — asserts the fan-in edge fires
  and D becomes reachable once both B and C are.

* 🔀 fix: match SDK OR semantics for multi-source edge reachability

Reverts the all-sources-required reachability gate from 4982f1c3b and
replaces it with an any-source-reachable model, which matches how
`@librechat/agents`'s `MultiAgentGraph.createWorkflow` actually wires
multi-source edges at runtime (per-source `builder.addEdge(source,
destination)`). With the previous `every` gate, a legitimate handoff
edge `{ from: ['A', 'B'], to: 'C' }` where B had no incoming path was
pruned along with C, regressing OR-semantics routing that the SDK
would otherwise handle correctly.

New behavior:

1. Reachability: an edge advances when ANY of its `from` endpoints is
   already reachable. Fixed-point iteration over `filteredEdges`.
2. Edge filter: keep an edge when it has at least one reachable source
   AND all destinations are reachable (a missing destination would
   still crash `StateGraph.compile` with `Found edge ending at unknown
   node`).
3. Agent prune: keep agents that are reachable OR referenced on any
   endpoint of a surviving edge. The second clause preserves co-sources
   in multi-source edges (B in `{ from: ['A','B'], to: 'C' }` when
   nothing else reaches B) so the SDK's per-source `addEdge` — and the
   `validateEdgeAgents` safety-net I added to the SDK in #111 — still
   finds B as a node.

The pass-audit A->B->C->D regression test continues to pass: with B
skipped, `filterOrphanedEdges` drops both B-adjacent edges, reachability
never expands past A, C->D has no reachable source so it gets filtered,
and C/D are pruned because they're neither reachable nor referenced.

* ✂️ fix: strip skipped co-members from multi-source/multi-dest edges

Addresses codex pass-9 P2 on #12740. `filterOrphanedEdges` previously
dropped an edge whenever any `from` id was skipped, which was correct
for scalar edges but over-aggressive for multi-source ones: the agents
SDK adds one `builder.addEdge(source, destination)` per source, so
`{ from: ['A','B'], to: 'C' }` with B skipped still has a valid
`A -> C` route that was being thrown away.

Now sanitize each endpoint:
- Scalar skipped → drop the whole edge (no route survives).
- Array with some skipped → strip the skipped ids, keep the edge with
  the surviving members. If the array empties out, drop the edge.

Symmetric handling for `to` covers multi-destination fan-out when one
co-destination is skipped. Tests updated/added:
- `strips skipped co-sources from multi-source edges…`
- `strips skipped co-destinations from multi-destination edges`
- `drops multi-member edges only when every member on a side is skipped`
- Discovery-side: `preserves valid routes when one co-source of a
  multi-source edge is skipped` asserts the end-to-end behavior —
  skipped co-source B gets stripped from the edge, A->C routing
  survives, and C remains in `agentConfigs`.

* 🔓 fix: respect SHARE-on-AGENT fallback for handoff ACL on API routes

Addresses codex pass-10 P1 on #12740. The API controllers were handing
`discoverConnectedAgents` a raw `PermissionService.checkPermission` call
against `ResourceType.REMOTE_AGENT`, but the route-level middleware
(`createCheckRemoteAgentAccess`) authorizes the primary agent via
`getRemoteAgentPermissions`, which first consults the AGENT ACL and
treats owners with the SHARE bit as remotely authorized even without
an explicit REMOTE_AGENT grant. The mismatch meant a user could open
the primary via `/v1/chat/completions` or `/v1/responses`, but their
own owned handoff sub-agents were silently skipped — breaking
multi-agent handoffs for the common "owner runs their own multi-agent
orchestrator" case.

Both controllers now pass `discoverConnectedAgents` a `checkPermission`
wrapper that delegates to `getRemoteAgentPermissions` (with
`getEffectivePermissions` injected from `PermissionService`) and
compares the returned bitmask against the required permission via
`hasPermissions`. Sub-agents are now authorized by the exact same
rules the route middleware applies to the primary.

* 🌱 fix: preserve user-defined parallel-start branches

Addresses codex pass-11 P2 on #12740. The post-filter reachability
prune seeded only from `primaryConfig.id`, which killed
`MultiAgentGraph`'s legitimate multi-start pattern — a user-defined
edge like `X -> Y` where X has no incoming path (X is an intentional
parallel starting node, run alongside the primary) was being dropped
because neither X nor Y was reachable from the primary.

Reconcile the tension with pass-4 ("prune accidental orphans when an
intermediate is skipped") by using pre-filter reachability as the
signal:

- An agent that WAS reachable from the primary via the original
  (pre-filter) edges but loses that path when `filterOrphanedEdges`
  runs is an accidental orphan (a skipped hop broke the chain) — prune.
- An agent that was NEVER reachable from the primary, even pre-filter,
  is an intentional parallel start — seed it into post-filter
  reachability so its component survives.

Surviving-edge endpoint references still keep an agent (co-sources in
multi-source edges). New test `preserves user-defined parallel-start
branches disconnected from the primary` covers the pass-11 scenario;
the existing `A->B->C->D, B skipped` regression test continues to
pass because C/D were pre-filter reachable through B and lose that
reachability after filtering.

* 🎯 fix: tighten parallel-start seed criterion to 'no pre-filter incoming edge'

Addresses codex pass-12 P1 on #12740. The pass-11 seed heuristic — 'agent
is in `agentConfigs` but was not pre-filter reachable from the primary' —
was too permissive. A downstream agent like Y in `X -> Y` where X gets
skipped (missing / no VIEW) was never pre-filter reachable from the
primary either, so the old rule promoted Y to a parallel start node and
discovery returned `agents: [primary, Y]` with no connecting edge. The
SDK then ran Y as an unintended parallel root — exactly the orphan
behavior pass-4 wanted to prevent.

Tighter criterion: seed a post-filter reachability root only when the
agent had NO incoming edge in the pre-filter graph. That matches
`MultiAgentGraph.analyzeGraph`'s "no-incoming-edge" definition of a
start node applied to the user's original declared topology, so:

- `A -> B` plus a user-defined `X -> Y` parallel branch: X has no
  incoming pre-filter → seeded → X and Y both survive.
- `A -> B` plus `X -> Y` with X skipped: Y had an incoming pre-filter
  (`X -> Y`) → NOT seeded → Y is pruned as the orphan it is.
- `A -> B -> C` with B skipped: C had an incoming pre-filter (`B -> C`)
  → NOT seeded → C is pruned.

New test `does not promote a downstream orphan to a parallel start when
its only upstream is skipped` locks in the pass-12 scenario. The pass-11
`preserves user-defined parallel-start branches` test continues to hold.

* 📁 fix: don't enforce AGENT-only file ACL on REMOTE_AGENT API callers

Addresses codex pass-13 P1 on #12740. When I refactored the API
controllers' DB-method bundle, I inadvertently started forwarding
`filterFilesByAgentAccess` into `initializeAgent`. That helper calls
`checkPermission` with `resourceType: ResourceType.AGENT`, but these
routes authorize callers through `REMOTE_AGENT` (via
`getRemoteAgentPermissions`). A user granted `REMOTE_AGENT_VIEWER` on
a shared agent but lacking direct `AGENT_VIEW` could invoke the agent
yet all its owner-attached context files would get silently filtered
out — breaking `file_search`/context retrieval for remote consumers.

Drop `filterFilesByAgentAccess` from the OpenAI-compat and Responses
controllers' `dbMethods` (and remove the now-unused import). The chat
UI's `initialize.js` keeps it since that path legitimately authorizes
at the AGENT level. No functional change inside the helper — passing
`undefined` simply tells `primeResources` to skip the per-file ACL
filter, restoring the pre-refactor API behavior.

* 🪓 fix: strip unreachable co-sources from surviving multi-source edges

Addresses codex pass-14 P1 on #12740. The earlier pass-8 fix kept any
agent referenced as an endpoint of a surviving edge (via a
`referencedByEdge` fallback) to avoid the SDK's `validateEdgeAgents`
failing on missing nodes. But that fallback propped up unreachable
co-sources too: with `[A -> C, X -> B, [B,C] -> D]` and X skipped,
`X -> B` gets filtered, the `[B,C] -> D` fan-in survives because C is
reachable, and B stays in `agentConfigs` solely because the fan-in
still lists it. `MultiAgentGraph.analyzeGraph` then sees B with no
incoming edge and runs it as an unintended parallel root.

Sanitize surviving edges instead: for a kept edge whose `from` is an
array, filter out any co-source that isn't reachable. The SDK's
per-source `addEdge` fires independently, so dropping an unreachable
co-source doesn't invalidate the remaining routes — in the scenario
above `[B,C] -> D` becomes `[C] -> D`, every endpoint of every
surviving edge is now reachable, and the agent prune collapses to a
strict `reachable.has(agentId)` check. No more referenced-by-edge
fallback.

Regression test added: `strips unreachable co-sources from surviving
multi-source edges (no stray parallel root)` — asserts B is absent
from every surviving edge endpoint and the fan-in's `from` is just
`['C']`. All 22 prior discovery tests still pass unchanged.

📐 fix: Align Summarization Trigger Schema with Documented and Runtime-Supported Types (#12735)
* 🐛 fix: accept documented `summarization.trigger.type` values

The Zod schema for `summarization.trigger.type` only accepted
`'token_count'`, but:

- the documentation lists `token_ratio`, `remaining_tokens`, and
  `messages_to_refine` as valid
- the `@librechat/agents` runtime only evaluates those three types and
  silently no-ops on anything else

The result was a double failure: any user following the docs hit a
startup Zod error, and anyone who matched the schema by using
`token_count` got a silent no-op at runtime where summarization never
fired.

Align the schema with the documented, runtime-supported trigger types.

Closes #12721

* 🧹 fix: bound `token_ratio` trigger value to (0, 1]

Per Codex review: the previous schema accepted `value: z.number().positive()`
for every trigger type. That meant `trigger: { type: 'token_ratio', value: 80 }`
(presumably meant as "80%") passed validation and then silently never fired —
because `usedRatio = 1 - remaining/max` is bounded at 1, so `>= 80` is always
false. That is exactly the silent-no-op pattern this PR is trying to eliminate.

Switch to a discriminated union so each trigger type has its own value
constraint:

- `token_ratio`: `(0, 1]` — documented as a fraction, so 80 is nonsense
- `remaining_tokens`: positive — token counts can be large
- `messages_to_refine`: positive — message counts can be > 1

Added tests for the upper-bound rejection and the inclusive upper bound
(`value: 1` still accepted as a valid "fire at 100%" extreme).

* 🧹 fix: accept `token_ratio: 0` per documented 0.0–1.0 inclusive range

Per Codex review: `.positive()` rejected `value: 0`, but the docs
describe the `token_ratio` range as `0.0–1.0` (both inclusive). Admins
who copy the documented lower bound into their YAML would fail schema
validation at startup.

Switch `token_ratio` to `.min(0).max(1)`. `0` is a valid (if extreme)
setting — the agents SDK's `usedRatio >= 0` check will fire as soon as
there is anything to refine, which is a legitimate "always summarize
when pruning happens" configuration.

`remaining_tokens` and `messages_to_refine` keep `.positive()`: both
are counts, and `0` there produces no meaningful behavior (the SDK
has an early return for `messagesToRefineCount <= 0`).

* 🐛 fix: preserve `token_ratio` trigger when `value: 0`

Per Codex review: now that the schema accepts `token_ratio: 0`,
`shapeSummarizationConfig` would silently drop it because of a truthy
check on `config?.trigger?.value`. The trigger would disappear and the
runtime would fall back to "no trigger configured" — which fires on any
pruning rather than honoring the explicit ratio.

Switch to `typeof value === 'number'`, which preserves `0` while still
rejecting `undefined`/`null`.

Added a regression test that asserts `{ type: 'token_ratio', value: 0 }`
survives the shaping function untouched.

* 🧹 fix: reject non-finite trigger values at schema level

Per Codex review: `z.number().positive()` still accepts `Infinity` and
`NaN` (via YAML `.inf`, `.nan`). Config validation would succeed, but
the agents SDK guards every trigger path with `Number.isFinite(...)` and
silently returns `false` — summarization never fires while the server
starts cleanly. That is the exact schema/runtime split this PR is trying
to eliminate.

Add `.finite()` to every trigger value. `token_ratio` already had an
implicit guard via `.max(1)`, but applying `.finite()` uniformly keeps
the intent obvious and catches `NaN` (which `.max(1)` does not).

* 🧹 fix: integer counts + targeted token_count migration warning

Two findings from the comprehensive review:

1. `remaining_tokens` and `messages_to_refine` are token/message counts
   and are always integers in the runtime (`Number.isFinite(...)` guards
   already assume integer semantics). `z.number().positive()` accepted
   fractional values like `2.5`, which was semantically confusing and
   would round oddly against the runtime's `>=` / `<=` comparisons. Add
   `.int()` to both count-based branches; `token_ratio` stays fractional.

2. Anyone upgrading with `trigger.type: 'token_count'` in their YAML got
   the generic "Invalid summarization config" warning plus a flattened
   Zod error. Detect that specific case in `loadSummarizationConfig` and
   emit a migration-friendly message that names the three valid
   replacements. Export the function so the behavior is unit-testable.

Also added a parameterized passthrough test covering `remaining_tokens`
and `messages_to_refine` shaping, complementing the existing
`token_ratio` coverage.

* 🧹 fix: accurate fallback wording + bare-string trigger test

Two nits from the follow-up audit:

1. The legacy-`token_count` warning claimed "Summarization will be
   disabled," but `shapeSummarizationConfig` treats a missing
   summarization config as self-summarize mode (fires on every pruning
   event using the agent's own provider/model). "Disabled" would
   mislead an admin into stopping investigation. Reword to describe the
   actual fallback and assert the new wording in the spec.

2. Add a regression test for the `trigger: 'bare-string'` YAML case, so
   the `typeof raw.trigger === 'object'` guard is exercised rather than
   implied.

3. Swap the en-dash in `(0–1)` for an ASCII hyphen so the log message
   is safe in every terminal/aggregator regardless of UTF-8 handling.

* 🔇 fix: cast `raw.trigger.type` to inspect legacy value past narrowed union

CI TS check failed: after the schema tightening, `raw.trigger.type` is
narrowed to `"token_ratio" | "remaining_tokens" | "messages_to_refine"
| undefined`, so the runtime comparison to `"token_count"` is a
TS2367 ("no overlap") error even though that's exactly the comparison
we want for the migration guard.

Widen just that one access via `as { type?: unknown }` so the migration
check reads runtime-shaped YAML input without the type system folding
it back into the narrowed union.

📝 fix: Preserve Raw Markdown Formatting on Upload as Text (#12734)
* 🐛 fix: Preserve Raw Markdown on `Upload as Text`

When `RAG_API_URL` is configured, `.md` uploads were sent to the RAG API
`/text` endpoint, which routes Markdown through `UnstructuredMarkdownLoader`
and strips formatting (`#`, `**`, lists, blockquotes). Users expect `Upload
as Text` to preserve raw content - identical bytes in a `.txt` file round-trip
verbatim, while the `.md` came back stripped.

Short-circuit the RAG API call for Markdown files (by MIME type or `.md` /
`.markdown` extension) and read the file verbatim via `parseTextNative`.
Non-Markdown paths are unaffected, and the embedding path (`/embed`) keeps
its existing loader so vector search quality is unchanged.

* 🐛 fix: normalize markdown MIME and accept `text/md`

Addressing review feedback on the `Upload as Text` short-circuit:

- Accept `text/md` in the markdown MIME set (LibreChat treats it as a
  valid markdown type elsewhere, e.g. the artifact-rendering prompt).
- Normalize the incoming MIME type (lowercase + strip parameters) before
  the set lookup so parameterized values like
  `text/markdown; charset=utf-8` and uppercase `TEXT/MARKDOWN` still
  short-circuit. Extensionless uploads relying only on the `Content-Type`
  header would otherwise fall through to the RAG `/text` endpoint and
  lose their markdown formatting.

Extend `text.spec.ts` parametrized cases with `text/md`, parameterized
MIME, uppercase, and whitespace-padded variants.

* 🧹 chore: Address Code Review Follow-ups on `Upload as Text` fix

Addressing comprehensive review feedback:

- Debug log now includes filename and MIME type so operators can
  identify which upload triggered the short-circuit without having
  to correlate other logs.
- Expand markdown extension detection beyond `.md` / `.markdown` to
  cover `.mdown`, `.mkdn`, `.mkd`, `.mdwn` (case-insensitive regex).
- Tighten `normalizeMimeType` parameter type from `string | undefined`
  to `string` to match the actual Express.Multer.File type. The
  falsy-check still protects against empty strings at runtime.
- Extend parametrized tests with the most common real-world shapes:
  `text/plain` + `.md` (the MIME most browsers/servers assign),
  the new rare extensions, and empty MIME + `.md` (pure extension
  fallback path).
- Add a positive assertion that `readFileAsString` was called with the
  expected arguments on every short-circuit case, so tests fail loudly
  if the native-parse path ever regresses.

* 🧪 test: Cover `.mdwn` regex branch in Markdown short-circuit

Every other alternation in `MARKDOWN_EXTENSIONS_RE` has at least one
test case (`md`, `markdown`, `mdown`, `mkdn`, `mkd`) but `mdwn` did
not, leaving a typo in that branch undetectable.

🪐 fix: Replace $bitsAllSet ACL Queries for Azure Cosmos DB Compatibility (#12736)
* 🐛 fix: replace `$bitsAllSet` ACL queries for Cosmos DB compatibility

Azure Cosmos DB for MongoDB API does not implement the `$bitsAllSet`
query operator, so every permission check against Cosmos DB threw. The
five read paths in `aclEntry.ts` (`hasPermission`, `findAccessibleResources`,
`findPublicResourceIds`, and two sites in `getSoleOwnedResourceIds`) now
fetch candidate entries and apply the bitwise mask in application code.
This matches the existing FerretDB-compatible pattern.

Fixes #12729.

* 🐛 fix: delegate `findPubliclyAccessibleResources` to fixed DB method

`AccessControlService.findPubliclyAccessibleResources` inlined the same
`$bitsAllSet` query as the data-schemas layer, which fails on Azure
Cosmos DB for MongoDB. Delegate to `_dbMethods.findPublicResourceIds`
so a single implementation carries the Cosmos-compatible bitwise logic.

Refs #12729.

* 🐛 fix: move `$bitsAllSet` filter out of remote-agent aggregation

`enrichRemoteAgentPrincipals` used `$bitsAllSet` inside an aggregation
`$match`, which Azure Cosmos DB for MongoDB does not implement. Project
`permBits` through the pipeline and filter for `PermissionBits.SHARE` in
application code. The extra documents fetched are bounded by ACL entries
on a single agent resource, so the cost is negligible.

Refs #12729.

* 🧪 test: rename misleading public-dedup test and add real dedup coverage

The test previously named "returns deduplicated IDs even if the public
principal has multiple entries" only set up a single ACL entry, so it
did not actually exercise deduplication. Split into two tests: one for
the happy path (single entry with required bits), and one that bypasses
`grantPermission`'s upsert via `AclEntry.create` to confirm the
application-layer dedup Map handles genuine duplicates.

Refs #12729.

* 🧪 test: cover SHARE-bit filter in `enrichRemoteAgentPrincipals`

The `$bitsAllSet` match stage in `enrichRemoteAgentPrincipals` previously
guaranteed every aggregation row had SHARE; the Cosmos DB fix moved that
check into a JS `continue` branch with no direct coverage. Add a
dependency-injected unit test that stubs the aggregation with mixed
SHARE / non-SHARE / zero-bit rows and asserts only SHARE holders are
enriched and queued for backfill. Also includes a regression guard that
the `$match` pipeline stage no longer contains a `permBits` filter.

Refs #12729.

* ♻️ refactor: extract `filterByBitsAndDedup` helper for ACL reads

`findAccessibleResources` and `findPublicResourceIds` each inlined the
same bitmask-filter + `Map`-based dedup loop. Lift it into a private
`filterByBitsAndDedup(entries, requiredBits)` helper so the Cosmos-DB
compatible pattern lives in one place. Pure rename/extract — no
behavior change.

Refs #12729.

* 📝 docs: fix stale `\$bitsAllSet` references in FerretDB spec

The describe block and header comment in the FerretDB parity spec still
referenced `\$bitsAllSet queries` after the Cosmos DB compatibility fix
moved the bit mask into application code. Update the title to
\"Bitwise permission queries\" and rewrite the header comment to
describe the application-layer behavior being validated.

Refs #12729.

*  perf: push permission-mask filter back to the database via `$in`

The original fix for #12729 moved `$bitsAllSet` filtering into application
code, which meant every ACL read fetched the full set of rows for a
principal/resource and filtered in JS. For tenants with large ACL
collections this inflates wire transfer and heap.

Replace the JS filter with `permBits: { $in: permissionBitSupersets(X) }`.
For the 4-bit `PermissionBits` enum the `$in` list is at most 16 values
(8 for a single-bit mask like SHARE). `$in` is indexable and supported by
Azure Cosmos DB for MongoDB, so the filter runs on the server again —
restoring `.distinct('resourceId')` and `findOne()` semantics.

`permissionBitSupersets(requiredBits)` is memoized and exported from
`@librechat/data-schemas`. Callers restored:
  - `hasPermission`: back to `findOne` short-circuit
  - `findAccessibleResources` / `findPublicResourceIds`: back to `.distinct()`
  - `getSoleOwnedResourceIds`: back to the `$match` + `$group` aggregation
  - `enrichRemoteAgentPrincipals`: bit filter back in `$match`, JS `continue` removed

Refs #12729.

* 🧪 test: add `\$bitsAllSet` vs `\$in` parity + perf spec

Introduces `aclEntry.parity.spec.ts` — a side-by-side spec that runs the
legacy `\$bitsAllSet` query and the current `\$in`-based query against the
same `mongodb-memory-server` fixture and asserts identical output sets for
every affected method (`hasPermission`, `findAccessibleResources`,
`findPublicResourceIds`, `getSoleOwnedResourceIds`) across all 7 meaningful
permBits combinations.

Also logs median wall-clock time for the two query paths over 20 runs on
an 800-entry fixture, with a loose 3x guard against catastrophic
regressions. Initial local numbers: 1.05 ms vs 1.07 ms
(findAccessibleResources), 1.10 ms vs 1.05 ms (findPublicResourceIds).

Refs #12729.

* 🔒 hardening: freeze `permissionBitSupersets` cache + enum-shape guard

Two defensive changes from the comprehensive audit:

* Cached superset arrays are now `Object.freeze`d and the return type is
  `readonly number[]`. Previously the cached arrays were returned by
  mutable reference, so a caller that mutated the result would silently
  corrupt the process-wide cache for every subsequent permission check.
  `Object.freeze` turns that into a loud `TypeError` at the mutation
  site. All existing call sites pass the result directly to Mongoose's
  `$in`, which does not mutate.
* Added a module-load guard `if (MAX_PERM_BITS === 0) throw`. If
  `PermissionBits` is ever refactored to a `const` object or string
  enum, `Object.values(...).filter(isNumber)` would return `[]` and
  `MAX_PERM_BITS` would silently become 0, making every query match no
  rows and breaking every permission check. The guard fails loudly
  instead.

Also collapsed four identical JSDoc lines across `hasPermission`,
`findAccessibleResources`, `findPublicResourceIds`, and
`getSoleOwnedResourceIds` into a single `{@link permissionBitSupersets}`
reference.

Refs #12729.

* 🧪 test: add focused unit tests for `permissionBitSupersets`

The helper is the single point of correctness for every ACL read path
(every query uses `permBits: { $in: permissionBitSupersets(X) }`), so it
warrants direct coverage independent of the higher-level parity and
behavior specs. Six cases added:

* `requiredBits=0` returns all 16 values
* `requiredBits=15` returns `[15]` only
* every returned value is a bitwise superset of `requiredBits`
* full parity against the `$bitsAllSet` definition for every
  `required` in 0..15
* memoization: repeat calls return the same frozen reference
* frozen result throws `TypeError` on mutation attempts

Refs #12729.

* 🧪 test: tighten parity perf guard and document fixture constants

The `expect(currentMs).toBeLessThan(legacyMs * 3 + 50)` form was
dominated by the `+ 50` additive term at typical sub-ms query
latencies — at legacy=1ms, a 50x regression would still pass. Replace
with `Math.max(legacyMs * 5, 50)` so the multiplicative ceiling is
intact once the new path climbs out of the fixed noise floor.

Also added inline rationale for the `FIXTURE_SIZE = 800` and
`PERF_ITERATIONS = 20` constants.

Refs #12729.

* 🧹 chore: remove stale perf-guard comment, hoist rationale to describe

Commit a75f122 left a "Sanity check: A 3x multiplier" comment block
above the first perf guard, and 21852ac layered a second
"Multiplicative-dominant guard" block directly below it. The stale
block described the `legacyMs * 3 + 50` formula that no longer exists,
so both blocks coexisted and contradicted each other.

Delete the stale block from the first test, remove the redundant copy
from the second test, and lift the (now-single) rationale to the
enclosing `describe('performance')` block. Each test is now one
`expect` line — the rationale lives once, at the scope it applies to.

Refs #12729.

* 📝 docs: sharpen MAX_PERM_BITS guard message + test-sort consistency

Two NITs from the follow-up audit:

* The `MAX_PERM_BITS === 0` guard now names the specific refactors that
  could cause it (const object / string enum / all-string shape) and
  gives two concrete remediation paths (rewrite the reducer, or give
  `permissionBitSupersets` an explicit bit-width parameter). Previously
  the message just said "update permissionBitSupersets before
  continuing", which was vague.
* The `requiredBits=15` unit test now applies the same
  `[...result].sort((a, b) => a - b)` normalization as the other tests
  so the set-equality assertions are uniform. The function happens to
  return values in ascending order, but the helper's JSDoc does not
  promise ordering, so sorting before comparing is the correct
  defensive pattern.

Refs #12729.

* 🔒 fix: enforce `permBits <= MAX_PERM_BITS` at the schema level

Codex flagged a real silent regression: `permissionBitSupersets`
enumerates `$in` candidates only in `[0, MAX_PERM_BITS]` (currently 15),
so any ACL row with bits above the enum — e.g. `permBits = 31` from a
future role or a manual DB write — would be excluded from reads that
`$bitsAllSet` would have matched. Current write paths only produce
values in `[0, 15]` via the `PermissionBits` / `RoleBits` enums, so
no live data is affected, but the schema did not prevent out-of-range
writes, so the divergence was reachable.

Fix: add `min: 0`, `max: MAX_PERM_BITS`, and an `isInteger` validator to
the `permBits` field in the AclEntry schema. `MAX_PERM_BITS` is derived
from `PermissionBits` the same way `permissionBitSupersets` computes it,
so when a new bit is added to the enum both the read-side enumeration
and the write-side bound expand together.

Tests: four new cases cover the upper bound, over-limit, negative, and
non-integer inputs, each asserting `Mongoose.Error.ValidationError`.
Plus updated JSDoc on `permissionBitSupersets` to document the
invariant that the schema now enforces.

Refs #12729.

* ♻️ refactor: hoist `MAX_PERM_BITS` + enum-shape/ceiling guards to shared util

Addresses one MINOR DRY finding and one NIT defensive-guard finding from
the latest audit. `MAX_PERM_BITS` was duplicated in `methods/aclEntry.ts`
and `schema/aclEntry.ts` with identical computations; they could silently
diverge. Move the constant plus both module-load guards to
`src/common/permissions.ts`:

* `MAX_PERM_BITS === 0` guard — fail loudly if `PermissionBits` is ever
  refactored to a `const` object or string enum (applied in both sites
  now, not just methods).
* `MAX_PERM_BITS > 255` guard — circuit-breaker for the `$in` enumeration
  strategy. At 4 bits the list tops out at 16; at 8 bits 256. Beyond
  that the approach degrades, so fail at module load rather than emit an
  unusably-large `$in` list.

Both the schema and the methods file now import from the single
`src/common/permissions.ts`. `readonly number[]` return type and
`Object.freeze` cache-value protection from the prior commits are
preserved.

Refs #12729.

* 🔒 fix: reject out-of-range `requiredBits` without caching (DoS fix)

Codex flagged a real unbounded-cache DoS vector:
`api/server/controllers/agents/v1.js` parses `req.query.requiredPermission`
via `parseInt` and forwards it unvalidated to `findAccessibleResources`,
which eventually calls `permissionBitSupersets(requiredBits)`. Because
the old code memoized *every* distinct input in a process-global Map,
an attacker could flood the cache with unique integers and grow memory
without bound.

Fix: when `requiredBits` is not an integer, is negative, or has any bits
set above `MAX_PERM_BITS`, return a single shared frozen empty array and
do NOT touch the cache. An empty `$in` list correctly matches zero rows
(rows cannot satisfy a bit we do not support), so the response is also
semantically correct — previously it "worked" only because invalid
inputs coincidentally expanded to `[]` too, but at the cost of a cache
entry each time.

Five new tests exercise the rejection path: upper-bound overflow, mixed
in-range+out-of-range bits, shared-instance identity across rejected
inputs, a 2000-unique-value cache-growth probe, and a regression check
that legitimate in-range inputs still get memoized normally.

Refs #12729.

* 🧪 test: probe `Map.prototype.set` to prove cache doesn't grow on rejection

Strengthens the DoS cache-growth test the review pass flagged: reference
identity alone allows a hypothetical regression like
`supersetCache.set(requiredBits, EMPTY_SUPERSETS); return EMPTY_SUPERSETS;`
to pass while still leaking one entry per attacker request.

Add a second test that spies on `Map.prototype.set`, records the global
call count before and after a burst of 1500 rejected inputs (500 each of
over-MAX integers, negatives, and non-integers), and asserts the delta
is zero. Manually verified the test has teeth: injecting the
hypothetical regression in the implementation produced exactly 1500
extra `Map.set` calls and the new test failed as expected; reverting
restored the clean state.

Renames the existing identity-based test to `(reference identity)` so
its scope is clear alongside the new `(Map-write probe)` companion.

🫧 feat: Claude Opus 4.7 Reasoning Visibility (#12701)
* 🫧 fix: Restore Claude Opus 4.7 Reasoning Visibility

Claude Opus 4.7 omits `thinking` content from Messages API responses by
default — empty thinking blocks still stream, but the `thinking` field is
blank unless the caller passes `display: "summarized"` in the adaptive
thinking config. This silenced the LibreChat "Thoughts" UI for Anthropic
(and Anthropic-on-Bedrock) adaptive models.

- Extend `ThinkingConfigAdaptive` in `packages/api/src/types/anthropic.ts`
  with an optional `display: 'summarized' | 'omitted'` field
- Emit `{ type: 'adaptive', display: 'summarized' }` from
  `configureReasoning` in `packages/api/src/endpoints/anthropic/helpers.ts`
- Emit `{ type: 'adaptive', display: 'summarized' }` from
  `bedrockInputParser` in `packages/data-provider/src/bedrock.ts` and
  update the local `ThinkingConfig` union
- Update existing adaptive-thinking assertions to include the new field
- Add dedicated tests asserting `display: 'summarized'` flows through
  both the Anthropic endpoint and the Bedrock parser

See https://platform.claude.com/docs/en/about-claude/models/whats-new-claude-4-7#thinking-content-omitted-by-default

* refactor: Gate `display: summarized` on Opus 4.7+

Narrow the reasoning-visibility opt-in to the models that actually omit
thinking content by default, instead of applying it to every adaptive
model. Pre-Opus-4.7 adaptive models (Opus 4.6, Sonnet 4.6) already return
summaries, so sending the field is unnecessary noise.

- Add `omitsThinkingByDefault(model)` in `packages/data-provider/src/bedrock.ts`
  that returns true only for Opus 4.7+ (including future majors like Opus 5+)
- Bedrock parser now only attaches `display: 'summarized'` when the helper
  matches, keeping the adaptive object unchanged for older models
- Anthropic endpoint `configureReasoning` uses the same helper so its emit
  path matches the Bedrock one
- Tests: replace the blanket `display: 'summarized'` assertions with
  model-specific ones (Opus 4.7 gets it, Opus 4.6 / Sonnet 4.6 do not),
  add a dedicated `omitsThinkingByDefault` suite covering naming variants
  and future versions

* feat: Configurable Thought Visibility for Anthropic Adaptive Models

Expose the Anthropic `thinking.display` API field as a user-facing
parameter so users can override the `auto` default (which stays as the
Opus-4.7+ opt-in added earlier in this PR). Also fixes the CI type error
by widening the adaptive thinking type assignment via a resolver helper
that returns a properly-typed object.

- Add `ThinkingDisplay` enum (`auto` | `summarized` | `omitted`) and
  matching zod schema in `packages/data-provider/src/schemas.ts`
- Add `thinkingDisplay` to `tConversationSchema`, `anthropicSettings`, and
  the pick lists for Bedrock input/parser + Anthropic agent params
- Add `resolveThinkingDisplay(model, explicit)` helper in
  `packages/data-provider/src/bedrock.ts` that returns the wire value or
  undefined (auto → model default, explicit → always honored)
- `bedrockInputParser` now reads `thinkingDisplay` from input and emits
  `display` only when the resolver returns a value; strips the field
  on non-adaptive-model branches so it does not leak
- `configureReasoning` in the Anthropic endpoint threads
  `thinkingDisplay` through, uses the resolver, and casts the adaptive
  config to `AnthropicClientOptions['thinking']` so the widened shape
  compiles against the stale installed SDK types
- Add UI slider for `thinkingDisplay` in `parameterSettings.ts` next to
  `effort`, with three-position `com_ui_auto` / `com_ui_summarized` /
  `com_ui_omitted` labels
- Add translation keys `com_endpoint_anthropic_thinking_display`,
  `com_endpoint_anthropic_thinking_display_desc`, `com_ui_summarized`,
  `com_ui_omitted`
- Add tests: `resolveThinkingDisplay` suite (5 cases covering auto /
  explicit / unknown input), parser round-trip tests for all three
  modes on Opus 4.6 and Opus 4.7, Anthropic endpoint tests for explicit
  summarized/omitted overrides

* fix: Drop `thinkingDisplay` When Adaptive Thinking Is Disabled

If a user turns adaptive thinking off but had previously selected a
`thinkingDisplay` value, the stale field was left in `additionalFields`
and ended up merged into the Bedrock request's
`additionalModelRequestFields`. That leaks a non-Bedrock key into the
payload and can round-trip back into `llmConfig`.

- Delete `additionalFields.thinkingDisplay` alongside `thinking` and
  `thinkingBudget` in the `thinking === false` branch of
  `bedrockInputParser`
- Add a regression test asserting `thinking`, `thinkingBudget`, and
  `thinkingDisplay` are all absent when adaptive thinking is disabled on
  an Opus 4.7 request

Reported by chatgpt-codex-connector on PR #12701.

* refactor: Consolidate `ThinkingDisplay` Types and Preserve Persisted Display

Address review findings on PR #12701:

- [Codex P2] `bedrockInputSchema.transform` now extracts
  `thinking.display` from persisted `additionalModelRequestFields` back
  into the top-level `thinkingDisplay` field so explicit `'omitted'`
  round-trips through storage instead of being silently reverted to
  `'summarized'` on the next parse.
- [Codex P2] `getLLMConfig` in the Anthropic endpoint now reads
  `.display` from a persisted `thinking` object (agents store the full
  Anthropic shape) and uses it as the fallback for `thinkingDisplay`
  when no top-level override is present.

  name) and the `ThinkingDisplayValue` alias in `bedrock.ts`.

  AnthropicClientOptions['thinking']` cast explaining the stale
  `@librechat/agents` SDK types that require it.
- Add tests: four round-trip cases asserting `bedrockInputSchema`
  recovers `display` from persisted AMRF (Opus 4.7 omitted, pre-4.7
  summarized, unknown-value ignore, explicit top-level wins), and two
  `getLLMConfig` cases asserting the Anthropic endpoint preserves and
  overrides persisted `thinking.display`.

* fix: Preserve Persisted `thinking.display` in bedrockInputParser

The parser constructed a fresh adaptive thinking config without looking at
any `display` already embedded in the incoming
`additionalModelRequestFields.thinking`. On round-trip through
`initializeBedrock`, a persisted user choice of `'omitted'` on Opus 4.7+
was silently reverted to `'summarized'` by the auto fallback.

- Extract `extractPersistedDisplay` helper and reuse it in both the
  schema transform (form-state round-trip) and the parser (wire-request
  round-trip)
- `bedrockInputParser` now feeds the persisted display as the resolver's
  explicit value when no top-level `thinkingDisplay` override is set
- Add regression tests: parser preserves `display: 'omitted'` for
  persisted Opus 4.7 AMRF, and top-level `thinkingDisplay` still wins
  over persisted AMRF display

🧊 fix: In-Memory Endpoint Token Config Cache Isolation (#12673)
* fix: endpoint token config not using shared cache in same process (initializing clients)

* refactor: Update default max context tokens for agent initialization

- Introduced a constant `DEFAULT_MAX_CONTEXT_TOKENS` set to 32000.
- Updated the `initializeAgent` function to use this constant instead of hardcoded values for maximum context tokens, improving maintainability and clarity.

* refactor: shared caching mechanism for token configuration

- Introduced a memoized in-memory cache for Keyv instances to ensure shared access across the same namespace, improving cache efficiency.
- Updated the `standardCache` function to utilize the new in-memory cache for the TOKEN_CONFIG namespace.
- Refactored the `initializeCustom` function to use the `tokenConfigCache` for better cache management.
- Removed redundant tokenCache parameter from `fetchModels` to streamline the function signature.

* fix: match TOKEN_CONFIG TTL and add memoization tests

Pass Time.THIRTY_MINUTES to tokenConfigCache() to match the TTL used
by getLogStores.js, preventing load-order-dependent expiry behavior.

Add 7 automated tests covering in-memory memoization: referential
identity, cross-call-site data sharing, namespace isolation,
first-caller TTL semantics, fallbackStore bypass, and tokenConfigCache
parity with direct standardCache access.

🔑 fix: Clear Stale Client Registration on invalid_client During OAuth Token Refresh (#12643)
* fix: clear stale client registration on invalid_client during token refresh

When a token refresh fails with `invalid_client`, the stored DCR client
registration is no longer valid on the authorization server. The existing
error handler only checked for `unauthorized_client` and returned null,
leaving the stale client_id cached in the database permanently. Every
subsequent token refresh attempt would fail with the same error.

Now when `invalid_client` is detected during refresh:
1. The stale client registration is deleted from the database
2. A `ReauthenticationRequiredError` is thrown to trigger a fresh OAuth
   flow with new dynamic client registration

Also passes `deleteTokens` from MCPConnectionFactory to getTokens() so
the cleanup has access to the token deletion method.

* fix: address review findings for stale client cleanup on token refresh

- Delete stale refresh token alongside client registration on invalid_client (Finding 1)
- Add tests for all new code paths: cleanup, warning, case-insensitivity, cleanup failure (Finding 2)
- Detect all vendor-specific client rejection patterns (client_id mismatch, client not found, unknown client) with case-insensitive matching (Finding 3)
- Use else-if for mutually exclusive error branches (Finding 4)
- Log warning when deleteTokens is not available on client rejection (Finding 6)
- Fix log message to say "attempting to clear" before async cleanup (Finding 7)
- Extract isClientRejectionMessage to shared utility, refactor MCPConnectionFactory.isClientRejection to use it

* fix: address followup review findings

- Extract isInvalidClientMessage (4 stale-client patterns) from isClientRejectionMessage
  to eliminate pattern duplication between utils.ts and tokens.ts (Finding 1)
- Remove redundant staleIdentifier variable, reuse identifier already in scope (Finding 2)
- Separate await from .then() on Promise.allSettled for readability (Finding 3)
- Add dedicated unit tests for isInvalidClientMessage and isClientRejectionMessage (Finding 4)
- Assert error message content in primary invalid_client test (Finding 5)
- Add JSDoc on deleteTokens in GetTokensParams (Finding 6)

🪪 feat: Optimized Entra ID Group Sync with Auto-Creation (#12606)
* feat: implement optimized Entra group sync with auto-creation

## Changes

### MUST FIX (Critical Issues) - RESOLVED

1. **BUG FIX: Prevent unintended user removal from existing groups**
   - ISSUE: db.syncUserEntraGroups() was called with only missing groups, causing removal
     from all existing Entra groups (full bidirectional sync behavior)
   - SOLUTION: Replaced with db.upsertGroupByExternalId() for each missing group followed
     by single bulkUpdateGroups() to add memberships (race-safe, idempotent)
   - BENEFIT: User memberships correctly maintained for mix of existing + new groups

2. **JSDoc @throws contradiction**
   - ISSUE: JSDoc declared function throws, but implementation catches all errors
   - SOLUTION: Removed @throws from JSDoc - function is best-effort
   - BENEFIT: Prevents unnecessary try/catch in caller code

3. **Missing test for group creation flow**
   - ISSUE: Auto-creating missing Entra groups had no test coverage
   - SOLUTION: Added regression test for mix of existing + new groups scenario
   - BENEFIT: Prevents future regressions on critical path

### SHOULD FIX (Important Improvements) - RESOLVED

4. **E11000 race condition handling**
   - SOLUTION: Upserts are idempotent and race-safe by design
   - BENEFIT: Concurrent logins no longer race each other

5. **Direct Mongoose access instead of db layer**
   - SOLUTION: Added findGroupsByExternalIds() helper to userGroup.ts
   - BENEFIT: Centralized data access, easier to add tenant scoping

6. **Serial DB round-trips on login path**
   - ISSUE: 40+ queries for user with 20 new groups
   - SOLUTION: Promise.all() for parallel upserts + single bulkUpdate
   - BENEFIT: ~10x performance improvement

7. **Graph API 429/503 throttling unhandled**
   - SOLUTION: Retry logic with exponential backoff (1s, 2s delays)
   - BENEFIT: Temporary API issues no longer cause permanent membership loss

8. **Sequential batch requests slow**
   - ISSUE: 200 groups = 10 batches × 200ms = ~2s sequential
   - SOLUTION: Promise.all() with concurrency limit (5 parallel batches)
   - BENEFIT: ~400ms total time

## Minor Fixes

- Removed dead code check
- PII removal: user._id instead of user.email in logs
- ES6 shorthand fixes
- Style consistency (blank lines)
- Projection optimization

## Verification

 npm run build - success
 npm run test:api - 61/61 passing (+ new regression test)
 npm run lint - no errors
 All feedback from danny-avila resolved

* docs: better JSDoc for the syncUserEntraGroupMemberships method

* refactor: consolidate Favorite type, harden controller, add tests

- Add canonical TUserFavorite type in data-provider, replace three
  duplicate definitions (data-service, data-schemas, store/favorites)
- Consolidate FavoritesController spec validation into single block,
  add return on 500 paths, add maxlength to mongoose sub-schema

- Add 22 backend tests for FavoritesController (spec validation,
  typeCount exclusivity, persistence, GET path)
- Add 40 frontend tests: useFavorites spec methods, useIsActiveItem
  observer lifecycle, ModelSpecItem pin button, FavoriteItem all three
  type branches, FavoritesList spec rendering

* fix: address PR review findings for pin model specs

- Harden backend validation to reject partial cross-type fields
  (e.g. spec+endpoint, agentId+model without endpoint)
- Add stale-spec auto-cleanup in FavoritesList mirroring agent cleanup
- Add type="button" to pin buttons in ModelSpecItem/EndpointModelItem
- Fix import order violations in EndpointModelItem and ModelSpecItem
- Remove hollow test, dead key prop, inline trivial helpers
- Fix misleading test description, add onSelectSpec to test mock
- Add return to controller success responses for consistency
- Add 6 backend tests for partial cross-type field validation

* fix: guard stale-spec cleanup against unloaded startupConfig

Prevents race condition where spec favorites are incorrectly deleted
on cold start before startupConfig has loaded. Mirrors the existing
agentsMap === undefined guard pattern used for stale agent cleanup.

Also adds tests for stale-spec cleanup persistence and fixes namespace
import pattern in FavoritesList.spec.tsx.

* fix: replace nested ternaries with if/else in FavoriteItem

Resolves ESLint no-nested-ternary warnings for name and typeLabel
derivations.

📂 fix: Respect supportedMimeTypes Config in File Picker Accept Filter (#12596)
* fix: respect supportedMimeTypes config in file picker accept filter

The browser file picker's accept attribute was hardcoded by provider
identity, ignoring the endpoint's supportedMimeTypes from fileConfig.
Users who configured permissive MIME types (e.g., '.*') still saw a
restrictive filter in the upload dialog.

Add isPermissiveMimeConfig utility that detects wildcard patterns in
the endpoint's supportedMimeTypes. When permissive, the file picker
accept attribute is set to empty (unrestricted). Non-permissive
configs retain the existing provider-based defaults.

Closes #12589

* fix: address review findings for isPermissiveMimeConfig

- Use non-standard MIME namespace probe (x-librechat/x-probe) so
  category-wildcard patterns like ^application\/.*$ no longer
  false-positive as permissive
- Add single-line JSDoc to isPermissiveMimeConfig
- Use !== undefined instead of != null (fileType is never null)
- Add endpointFileConfig to dropdownItems useMemo deps to prevent
  stale closure when config changes without endpoint change
- Add tests for broad application and multi-category patterns

* fix: wrap handleUploadClick in useCallback to satisfy exhaustive-deps

handleUploadClick is captured inside the dropdownItems useMemo but was
not in its dependency array. Wrap it in useCallback with
endpointFileConfig.supportedMimeTypes as the sole dependency, then
reference the stable callback in the useMemo deps.

⏱️ refactor: User Job Tracking TTL and Proactive Cleanup to Redis Job Store (#12595)
* refactor: Add user job tracking TTL to RedisJobStore

- Introduced a new TTL for per-user job tracking sets, set to 24 hours, to enhance job management.
- Updated RedisJobStoreOptions interface to include userJobsSetTtl for configuration.
- Modified job creation and deletion methods to manage user job sets effectively, ensuring proper expiration and cleanup.
- Enhanced comments for clarity on the new TTL functionality and its implications for user job tracking.

* fix: Address review findings for user job tracking TTL

- Remove redundant `del(userJobsKey)` in `getActiveJobIdsByUser` that
  raced with concurrent `createJob` on other replicas (Redis auto-deletes
  empty Sets after SREM)
- Guard `userJobsSetTtl: 0` from silently destroying tracking sets
  (`EXPIRE key 0` deletes the key on Redis 7.0+)
- Extract `deleteJobInternal` so `cleanup()` reuses the already-fetched
  userId instead of issuing a redundant HGETALL per stale job
- Add integration tests for TTL behavior, proactive SREM, configurable
  userJobsSetTtl, and TTL refresh on repeated createJob

* fix: Address follow-up review findings for RedisJobStore

- Use deleteJobInternal in cleanup() terminal-but-in-running-set path
  to ensure userJobsKey SREM is not skipped
- Clear local caches in deleteJob before the fallible getJob call so
  they are cleaned even on transient Redis errors
- Add proactive SREM tests for aborted and error terminal statuses
- Add test for tenant-qualified user tracking key format

* fix: Preserve completedTtl for non-running jobs in cleanup()

The cleanup() terminal-status branch should only remove tracking set
membership, not delete the job hash. deleteJobInternal bypasses the
completedTtl window that updateJob already applied, causing clients
polling for final status to lose the job data early.

🧮 fix: Atomize Redis Event Sequence Counters for Multi-Replica Deployments (#12578)
* fix: atomize Redis event sequence counters for multi-replica deployments

Replace in-memory sequenceCounters Map with shared atomic Redis counter
(INCR via Lua script) so all replicas share an authoritative sequence
source. Make syncReorderBuffer async to read current sequence from Redis
instead of defaulting to 0 on non-publishing replicas.

Closes #12575

* fix: harden emitChunk error handling and syncReorderBuffer race safety

Wrap getNextSequence inside emitChunk's try/catch so a transient Redis
failure is logged-and-swallowed, preserving the non-fatal chunk emission
contract. In syncReorderBuffer, replace pending.clear() with selective
discard of stale entries (seq < currentSeq) followed by
flushPendingMessages, preventing loss of chunks that arrived during the
async GET window.

* fix: address review findings — harden error paths, validate types, DRY tests

- Wrap syncReorderBuffer in try/catch in GenerationJobManager.subscribe()
  so a Redis GET failure degrades gracefully instead of crashing SSE reconnect.
- Validate eval return type in getNextSequence; throw on unexpected type
  instead of silently computing NaN/-1 and dropping all messages.
- Add NaN guard to parseInt in syncReorderBuffer for corrupted Redis values.
- Consolidate two streams loops in destroy() into a single pass.
- Extract createMockPublisher to shared helpers/publisher.ts (DRY).
- Add tests for eval failure and unexpected eval return type in emitChunk.
- Document performance tradeoff (2x RTT per emit) and TTL rationale.

* test: add cross-replica integration tests for sequence desync fix (#12575)

Three real-Redis tests that reproduce the exact multi-replica failure:

- Late subscriber on a different replica syncs to the shared counter
  and receives chunks immediately (no 500ms force-flush).
- Multiple subscribe/unsubscribe cycles across replicas maintain
  correct sequence alignment on every reconnect.
- Shared counter key is cleaned up when the stream is destroyed.

* fix: close syncReorderBuffer race, stop destroy() from nuking shared keys

- Replace selective prune with Math.min(currentSeq, minPendingSeq) so
  chunks that arrive in pending during the async GET window are preserved
  instead of incorrectly pruned. Since unsubscribe() already clears
  pending, any entries at sync time are live messages from the current
  subscription and must not be discarded.
- Remove DEL from destroy() — the sequence key is shared across replicas
  and a shutting-down instance must not nuke it for active publishers.
  Keys expire naturally via their 1-hour TTL; cleanup() handles
  single-stream lifecycle teardown.
- Add race-condition test: pauses GET, injects a message into pending
  during the window, resolves GET, asserts the chunk is delivered.
- Add emitDone/emitError eval failure tests to cover the asymmetric
  error contract (chunk swallows, done/error propagates).
- Add explicit MockPublisher return type to helpers/publisher.ts.

* fix: context-aware syncReorderBuffer to prevent duplicate delivery, silence test logs

The Math.min(currentSeq, minPending) fix from the prior commit correctly
handles the cross-replica race (chunk arriving during async GET), but
causes duplicate delivery in same-replica mode: onAbort subscribes to
the Redis channel during createJob, so chunks published before
subscribe() may arrive via pub/sub AND earlyEventBuffer. The Math.min
logic then flushes the pub/sub copy as a "live" message.

Fix: add a clearPending parameter to syncReorderBuffer. The manager
passes true when earlyEventBuffer was replayed (same-replica: pending
entries are duplicates → clear them) and false/undefined when it was
not (cross-replica: pending entries are live → preserve via Math.min).

- Silence winston logger in stream test files via logger.silent = true,
  following the existing pattern in data-schemas/prompt.spec.ts.
- Remove sequence key DEL from destroy() — shared across replicas,
  a shutting-down instance must not nuke the counter for active
  publishers. Keys expire via TTL; cleanup() handles stream teardown.

* fix: share publisher client in cross-replica tests for Redis Cluster compat

The cross-replica tests created publisherB via (ioredisClient as Redis)
.duplicate(), which produces a plain Redis connection to a single node.
In Redis Cluster, GET/EVAL on this client can't follow MOVED redirects,
so syncReorderBuffer reads null → nextSeq=0 → chunks are buffered.

Fix: share ioredisClient as the publisher for both replicas. It's the
correct Cluster-aware client and handles slot routing automatically.
Only subscriber connections need to be separate (pub/sub requirement).

* fix: increase cross-replica test timeouts and use polling for CI cluster

Replace fixed 300ms delivery waits with polling (50ms intervals, 2s max)
to handle Redis Cluster's cross-node pub/sub broadcast latency in CI.
Increase subscription activation wait from 100ms to 500ms to match the
pattern used by existing same-instance tests.

* chore: silence winston logs in remaining stream test files

Add logger.silent = true to GenerationJobManager, RedisJobStore, and
collectedUsage test files, matching the pattern already applied to
RedisEventTransport and reconnect-reorder-desync tests.

* fix: remove flaky cluster pub/sub tests, fix log suppression for resetModules

Remove two cross-replica transport-level integration tests that are
inherently non-deterministic in Redis Cluster: cluster pub/sub fan-out
is async across nodes, so pre-subscribe PUBLISHes can arrive at the
subscriber's node after SUBSCRIBE takes effect, causing random +/- 1
message counts. The core logic is already covered by deterministic unit
tests (mock publisher) and GenerationJobManager integration tests
(end-to-end with earlyEventBuffer). The cleanup test is retained.

Switch log suppression from logger.silent (which doesn't survive
jest.resetModules) to jest.spyOn(console, 'log').mockImplementation()
for files that use resetModules (GenerationJobManager, RedisJobStore,
collectedUsage). The logger.silent approach remains for files that
don't use resetModules (RedisEventTransport, reconnect-reorder-desync).

* fix: replace Lua EVAL+TTL with plain INCR, preserve live chunks during same-replica sync

P1: syncReorderBuffer with clearPending=true was unconditionally clearing
pending, dropping NEW chunks (seq >= currentSeq) from ongoing generation
that arrived via pub/sub during the async GET. Fix: selectively prune
only entries with seq < currentSeq (duplicates of earlyEventBuffer) and
flush remaining live entries.

P2: The 1-hour TTL on sequence keys could expire mid-stream during long
quiet periods (e.g., slow tool calls), restarting the counter from zero
and causing subscribers to silently drop all subsequent messages. Fix:
remove the Lua EVAL+EXPIRE script entirely and use plain Redis INCR —
no TTL. Keys are cleaned up explicitly by cleanup()/resetSequence()
when streams end. Orphaned keys from crashed processes are a few bytes
each, negligible compared to the production risk of TTL expiry.

- Update mock publisher helper: eval → incr
- Remove "unexpected eval type" tests (not applicable to incr)
- Update remaining eval error tests to reference incr

* fix: re-arm flush timeout after syncReorderBuffer when gaps remain

syncReorderBuffer clears flushTimeout before processing, but if pending
still has gaps after flushPendingMessages, no timeout is re-armed.
Without new messages arriving to trigger scheduleFlushTimeout, those
buffered entries sit indefinitely — stalling the stream after reconnect.

* chore: address final review — fix stale docs, rename clearPending, tighten tests

Fix all 10 findings from final review pass:

F1: Fix stale TTL comment in destroy() — no TTL exists after EVAL removal
F2: Fix stale EVAL reference in emitChunk JSDoc → INCR + PUBLISH
F3: Fix syncReorderBuffer JSDoc — describes old broken behavior, not
    the current selective prune
F4: Rename clearPending → pruneStaleEntries for clarity at call sites
F5: Add publish-not-called assertion to INCR failure test
F6: Replace Math.min(...spread) with explicit loop to avoid heap alloc
F7: Remove resetSequence from IEventTransport interface (no external
    callers; implementation detail only)
F8: Consolidate cleanup/resetSequence overlap — cleanup() owns the DEL,
    resetReorderBuffer() (now private) handles buffer state only
F9: Fix import order in reconnect test (value before type imports)
F10: Export MockPublisher interface from helpers/publisher.ts

* chore: fix stale resetSequence references and hadBufferReplay JSDoc

Two comments referenced resetSequence() which was removed in the F7/F8
refactor (now private resetReorderBuffer(), which doesn't DEL the key).
Only cleanup() deletes the Redis key. Also update hadBufferReplay JSDoc
to say "prune stale entries" instead of the pre-refactor "clear pending".

* chore: grammar

* fix: use earlyReplayCount as prune cutoff instead of Redis counter

The boolean pruneStaleEntries flag used currentSeq (from Redis GET) as
the prune threshold, but INCR can advance the counter past a live
chunk's seq during the GET window. Example: earlyEventBuffer held seqs
0-4, generation emits seq 5 during GET, INCR advances counter to 6,
GET returns 6, prune condition 5 < 6 deletes the live chunk.

Fix: pass the earlyEventBuffer replay count (5) as the prune cutoff.
Entries with seq < earlyReplayCount are true duplicates; entries at or
above are live regardless of what the Redis counter reads. After
pruning, the unified Math.min(currentSeq, minPending) logic handles
both same-replica and cross-replica paths correctly.

Add a targeted test that exercises this exact race: pauses GET, emits
seq 5 during the window, resolves GET with counter=6, asserts seq 5
is preserved (would have been dropped with the old boolean approach).

* fix: pass earlyReplayCount for skipBufferReplay path to prune pub/sub duplicates

When skipBufferReplay is true (resume scenario), earlyEventBuffer events
are delivered via the resume sync payload, not replayed directly. But
earlyReplayCount was left at 0, so syncReorderBuffer treated all pending
entries as live — meaning delayed pub/sub copies of those buffered
events could be delivered again, duplicating content.

Fix: capture earlyEventBuffer.length before the skip/replay branch so
the count is always passed to syncReorderBuffer regardless of delivery
method. Seqs 0..earlyReplayCount-1 are pruned as duplicates whether
they were replayed or delivered via sync payload.

* fix: keep nextSeq monotonic in syncReorderBuffer after async GET

handleOrderedChunk can deliver in-order messages and advance nextSeq
during the async GET window. If those messages leave pending empty,
the unconditional nextSeq = currentSeq could regress nextSeq below
its already-advanced value, reopening a delivered gap and causing
subsequent messages to be buffered until force-flush.

Fix: wrap both nextSeq assignments with Math.max(nextSeq, ...) so
syncReorderBuffer never moves the delivery frontier backward.

* fix: cap nextSeq at earlyReplayCount, add 24h safety TTL, add post-GET race test

Finding 1 (CRITICAL): When earlyReplayCount > 0 and pending is empty,
nextSeq was set to currentSeq — but INCR can advance the counter past
a live chunk whose pub/sub hasn't arrived yet. Cap at earlyReplayCount
instead (what was actually delivered), so in-flight chunks are not
skipped. Adds test for the message-arrives-AFTER-GET-resolves scenario.

Finding 3: Add a 24-hour safety-net TTL set once on first INCR only
(val === 1), never refreshed. This caps orphan lifetime from crashed
processes without risking mid-stream counter resets.

Finding 6: Replace setTimeout(100) in cleanup test with polling loop.

Finding 9: Fix variadic DEL mock + add expire mock for the new TTL.

Revert P2 fix (earlyReplayCount for skipBufferReplay path) — when
skipBufferReplay is true, the resume sync payload delivers everything
up to currentSeq, so syncReorderBuffer should trust the Redis counter
as the frontier, not the buffer length.

* chore: log expire failures consistently with other fire-and-forget errors

🧬 fix: Merge Custom Endpoints by Name Instead of Replacing Entire Array (#12586)
* fix: Merge Custom Endpoints by Name Instead of Replacing Entire Array

The DB base config's `endpoints.custom` array was wholesale-replacing
the YAML-derived array, causing YAML endpoint additions to be silently
lost after the first admin panel save. Add path-aware array merging
to `deepMerge` so keyed arrays (matched by `name`) are merged item-by-item
instead of replaced.

* fix: Harden mergeArrayByKey — deduplicate, sanitize, and prevent mutation

- Remove redundant sourceOrder array; iterate Map.keys() instead to
  prevent duplicate entries when source contains repeated names.
- Sanitize override-only appended items through deepMerge to enforce
  UNSAFE_KEYS prototype-pollution protection on all code paths.
- Shallow-copy unmatched base items to prevent mutation leak-back.
- Add post-OVERRIDE_KEY_MAP remapping note to ARRAY_MERGE_KEYS JSDoc.
- Add tests: duplicate source names, base mutation safety, multi-priority
  sequential merging of the same custom endpoint.

* fix: Add inline comments and test for keyless source items

- Document keyless item drop behavior in mergeArrayByKey with inline
  comment and matching test case.
- Add last-write-wins comment to deduplication test assertion.
- Clarify path semantics in mergeArrayByKey target-iteration comment.

* fix: Relocate keyless-item comment and test target-side preserve

- Move keyless-item comment to the if-guard where the skip happens and
  clarify that target-side keyless items are preserved, not dropped.
- Add test verifying base items without a name field are kept in output.

🧑‍🎨 refactor: Prompts/Sidebar styles for improved UI Consistency (#12426)
* style(sidebar): polish button styles, icon sizes, and nav separator

- Match new chat button style to sidebar toggle

- Unify icon sizes and stroke weights across sidebar icons

- Add separator between new chat and nav links

feat(prompts): inline prompt editing with route-based navigation

- Show prompts dashboard inline when editing/creating from chat

- Use route-based navigation instead of state-driven view switching

- Strip inline view to form-only without duplicate sidebar

style(prompts): unify borders, backgrounds, and admin controls

- Unify borders to border-medium and remove opaque backgrounds

- Add admin/advanced controls to sidebar

- Match chat background, move advanced toggle to versions panel

refactor(prompts): consolidate list actions into dropdown with compact layout

- Unify prompt list to single ChatGroupItem with all actions

- Consolidate actions into dropdown menu

- Distinct dropdown icons with status icon tooltips

- Remove rename action, use Trash icon matching convo items

refactor(prompts): inline-edit title with click-to-edit and save indicator

- Click title text to enter edit mode with pencil icon on hover

- Clean title input with inline save status indicator

- Uniform h-9 header height, smaller title, icon-only save status

- Remove separate edit icon button and confirm/cancel controls

style(prompts): sticky click-to-edit pill with surface-primary background

fix: preserve AuthContext identity across Vite HMR updates

createContext() was re-executed on every HMR module replacement, creating
a new context object that disconnected the existing provider from its
consumers. useAuthContext() would throw because useContext(newContext)
returned undefined while the provider was still on the old context.

Stash the context object in import.meta.hot.data so it survives HMR
re-execution. Dead-code-eliminated in production builds.

feat: add advanced prompts editor toggle to Chat settings

- Add AdvancedPrompts switch in Settings > Chat that maps the
  promptsEditorMode enum (simple/advanced) to a boolean toggle
- Preserve existing behavior: switching to simple forces alwaysMakeProd
- Add focus styling to PromptName input (border-medium on focus,
  outline on focus-visible, no ring)
- Add localization keys: com_nav_advanced_prompts,
  com_nav_advanced_prompts_desc
- Various Prompts UI refinements

style(sidebar): update nav icons and reorder links for clarity

- Prompts: MessageSquareQuote → NotebookPen (distinct from chat bubble)
- Agent Builder: Blocks → Bot (no longer identical to Assistants)
- Memories: Database → BrainCircuit (brain + AI circuit)
- Parameters: Settings2 → SlidersHorizontal (tuning-specific)
- Reorder: Chat → Prompts → Agents → Assistants → Memories →
  Bookmarks → Files → Parameters → MCP (frequency and grouping)

refactor(prompts): remove AdvancedSwitch component

The simple/advanced toggle is now in Settings > Chat, making
the standalone AdvancedSwitch redundant. Remove the component,
its barrel exports, and all render sites (PromptForm,
DashBreadcrumb, PromptsView).

style(prompts): tighten panel layout and spacing to match sidebar conventions

- Remove top margin from form wrapper, add mt-2 to header row
- Reduce header gaps and remove flex-wrap for tighter alignment
- Shrink prompt title from text-lg/h-9 to text-base/h-8
- Add pl-2 inner padding to PromptName input and static button
- Compact versions panel and deploy button container padding
- Reduce editor header and content spacing
- Compact mobile versions panel header

fix(prompts): rebuild mobile versions panel with proper transitions

- Add background (bg-surface-primary-alt) and border-l so content
  doesn't bleed through
- Replace conditional render with CSS opacity/translate so both
  overlay fade-out and panel slide-out animate on close
- Use inert attribute to disable focus when panel is hidden
- Replace raw × character with X icon from lucide-react
- Use size-icon button variant for close instead of text sm
- Use Tailwind classes (w-80, translate-x-full) instead of inline
  style object for width and transform
- Remove unused sidePanelWidth constant
- Overlay stays in DOM with pointer-events-none when hidden

chore: remove stale tooling artifacts

Remove .bg-shell/manifest.json and .gsd symlink that were
accidentally committed — these are local dev tooling files.

fix: resolve review issues in PromptName and ChatGroupItem

- Fix Escape/onBlur race in PromptName via cancelledRef guard
- Clear existing timer before creating new one to prevent status flicker
- Guard delete mutation against empty group id
- Attach menuButtonRef to MenuButton for proper focus restoration after preview dialog closes

fix: address review findings across prompts UI and sidebar

PromptName:
- Fix Enter key double-save: set skipBlurRef before inline save to prevent
  onBlur from re-firing saveName on input unmount
- Add isError prop to distinguish mutation failure from success, preventing
  false 'saved' checkmark on error
- Remove dead cn ternary that always evaluated to opacity-100
- Remove unused cn import

PromptForm:
- Pass isError from updateGroupMutation to PromptName
- Remove dead default arg (= {}) on function component

ChatGroupItem:
- Stabilize handleDelete via ref pattern to prevent memo-defeating
  recreation on every render (deleteGroup is a new ref each render)
- Disable delete button during mutation to prevent double-fire

ExpandedPanel:
- Restore <a> element for NewChatButton to fix middle-click (open in
  new tab) regression caused by anchor-to-button migration

DashGroupItem:
- Delete dead file (no longer exported or imported anywhere)

fix: address review findings across prompts UI and sidebar

- PromptName: render error state (red X) when save fails, extract
  shared commitName helper to deduplicate blur/Enter save paths
- ChatGroupItem: navigate away after deleting the active prompt in
  sidebar view; use context-aware route prefix (/prompts vs /d/prompts)
  for edit and card-click navigation
- InlinePromptsView: redirect to /c/new when user lacks prompts access
  instead of rendering a blank screen
- Remove dead ManagePrompts component and its barrel exports (no
  remaining consumers after GroupSidePanel cleanup)

fix: remove duplicate showThinking Recoil atom key

The 'showThinking' key was defined in both store/settings.ts (Recoil)
and store/showThinking.ts (Jotai). Only the Jotai atom is consumed;
the stale Recoil duplicate causes 'A key option with a unique string
value must be provided' at startup.

refactor: remove /d/prompts dashboard route and dead code

The prompts UI now lives at /prompts/* inline under the chat layout.
The old /d/prompts/* dashboard route, its layout (PromptsView), and
its breadcrumb (DashBreadcrumb) are no longer used.

- Delete PromptsView and DashBreadcrumb (zero consumers)
- Delete BackToChat button (zero consumers)
- Replace /d/prompts/* child routes with a redirect to /prompts/new
- Add /prompts index route that redirects to /prompts/new
- Update all /d/prompts navigation to /prompts:
  - ChatGroupItem: always use /prompts prefix
  - NoPromptGroup: navigate to /prompts
  - CreatePromptForm: fallback navigate to /prompts/:id
  - CreatePromptButton: simplified to /prompts/new (no dual-path)
- Strip GroupSidePanel of dashboard-only breadcrumb nav, recoil
  state clearing, and useDashboardContext dependency

refactor: remove dead Dashboard code and unused translation keys

- Delete DashboardContext provider (zero remaining consumers)
- Simplify DashboardRoute layout to a plain Outlet
- Remove commented-out file/vector-store route blocks
- Change catch-all redirect from /d/files to /c/new
- Remove 7 unused translation keys (com_nav_toggle_sidebar,
  com_ui_back_to_chat, com_ui_dashboard, com_ui_delete_prompt_name,
  com_ui_global_group, com_ui_prompt_renamed, com_ui_rename_prompt,
  com_ui_rename_prompt_name)

fix: add Babel plugin to transform import.meta.hot for Jest

`babel-plugin-transform-import-meta` handles standard properties (url,
filename, dirname, resolve) but not Vite's `hot` property. Jest runs in
CommonJS where `import.meta` is unavailable, so `import.meta.hot` in
AuthContext.tsx (added for HMR preservation) causes a SyntaxError that
breaks 27 test suites.

Add a small Babel plugin that replaces `import.meta.hot` with `undefined`
during Jest transforms, making the HMR guard blocks dead-code in tests.

fix: address review findings — inert typing, accessibility, and cleanup

- Add React type augmentation for `inert` attribute (React 18 compat)
- Replace spread hack `{...{ inert: }}` with direct prop in all 3 files
- Add `aria-hidden` to mobile overlay in PromptForm for screen readers
- Simplify deleteGroupRef pattern to direct mutation call
- Remove unused `useEffect` import and stale useMemo dependency
- Add clarifying comment for skipBlurRef mechanism in PromptName

fix: mobile UX for marketplace and prompts views

- Remove mobile new chat button from chat history section
- Add OpenSidebar entry points to marketplace and prompts views on mobile
- Move marketplace admin settings to a compact mobile top row
- Restructure prompt forms to surface category selector beside sidebar toggle
- Make versions panel slide content like the main sidebar and drop redundant borders
- Collapse versions button to icon-only on mobile
- Remove theme selector from prompt panel navigation

* fix: address PR review findings for prompts refactor

- Preserve prompt ID in /d/prompts/:id → /prompts/:id redirect
- Gate PreviewPrompt and VariableDialog behind isChatRoute to avoid
  mounting dead dialogs in dashboard mode
- Add onError handler to useDeletePromptGroup and close dialog on
  success
- Use useId() instead of hardcoded labelId in AdvancedPrompts
- Extract shared lazy loader for InlinePromptsView routes

* fix: complete review fixes for prompts refactor

- Move OGDialog (delete) inside isChatRoute gate with other dialogs
- Use useId() for both Switch id and label id in AdvancedPrompts
- Add com_ui_prompt_delete_error i18n key for actionable error context
- Drop no-op useCallback on handleDelete (unstable deleteGroup dep)

* refactor: hoist promptPath to module-scope constant

Eliminates stale-closure lint concern in dropdownItems useMemo and
removes the unnecessary dep array entry from onCardClick.

* refactor(sidebar): update icons and reorder links for clarity

- Replace Blocks icon with OpenAIMinimalIcon for the Assistant Builder link.
- Update Memories icon from BrainCircuit to Brain.
- Reintroduce Prompts link conditionally based on access permissions.
- Change Conversations icon from MessageSquare to MessagesSquare for consistency.

* refactor(sidebar): update icons and improve file attachment link

- Replace NewChatIcon with SquarePen in the NewChatButton for better visual consistency.
- Change AttachmentIcon to Paperclip in the file attachment link for clarity.

* refactor(sidebar): update file attachment icon for consistency

- Replace Paperclip icon with AttachmentIcon in the file attachment link for improved clarity and visual consistency.

* refactor(admin-settings): remove unused button and streamline dialog integration

- Eliminate the Admin button and its associated icon from the AdminSettings component for a cleaner interface.
- Simplify the confirm dialog integration by directly using the OGDialog without the button trigger.

* fix: context HMR issue

* style(prompts): enhance component structure and accessibility

- Update AutoSendPrompt button class for improved styling.
- Refactor List component to streamline loading and empty states.
- Ensure FilterPrompts handles context gracefully with null checks.
- Modify GroupSidePanel to prevent rendering without context.
- Simplify PromptsAccordion layout for better readability.
- Adjust CategoryIcon fallback behavior for undefined categories.

* refactor(useMCPServerManager): clean up import statements

- Remove duplicate import of MCPServerInitState for better clarity and organization.
- Adjust import order to maintain consistency with project structure.

* refactor(GroupSidePanel): restructure layout for improved readability and accessibility

- Adjust the structure of the GroupSidePanel component to enhance layout clarity.
- Move the PanelNavigation component into a more appropriate position within the hierarchy.
- Ensure consistent styling and behavior based on the isChatRoute condition.

* style(GroupSidePanel): adjust padding for improved layout consistency

- Update padding in the GroupSidePanel component to enhance visual alignment and readability.
- Ensure consistent styling across the component for a better user experience.

* fix(Conversations): add cache clearing and row height recomputation on search query change

- Implement useEffect to clear cache and recompute row heights when the search query changes.
- Enhance performance and responsiveness of the Conversations component during search operations.

* refactor(GroupSidePanel, PromptsAccordion): simplify layout and improve styling

* chore: import order

* fix: redirect users without CREATE permission from /prompts/new

Users with USE but not CREATE permission were seeing a blank page at
/prompts/new because InlinePromptsView only checked USE access.
CreatePromptForm's internal redirect was bypassed by the onSuccess
prop always being passed. Add CREATE check in InlinePromptsView so
the redirect happens before CreatePromptForm mounts.

* fix: restore dropdown actions for all routes and handle non-creator landing

- Remove isChatRoute gate on dropdown menu so preview, edit, and
  delete actions are available on the prompts management route
- Un-gate PreviewPrompt and OGDialog (delete) since both are
  triggered from the now-always-visible dropdown
- Keep VariableDialog gated behind isChatRoute (chat submission only)
- Show EmptyPromptPreview for non-creators at /prompts/new instead
  of redirecting to /c/new, so they stay in the prompts section
  with sidebar access to browse existing prompts

* fix: add isPublic to TPromptGroup type

The database schema (IPromptGroup in data-schemas) has isPublic but
the shared TPromptGroup type in data-provider was missing it,
causing a TS2339 error in ChatGroupItem.

* fix: prevent duplicate rename and restore name on error in PromptName

- Block re-entry to edit mode while a save is in flight by guarding
  the click handler with isLoading/saveStatus checks
- Reset newName to the prop value when mutation fails so the UI
  doesn't display the unsaved name after the error icon clears

* fix: address review findings across prompts refactor

- Consolidate duplicate usePromptGroupsContext() calls in PromptForm
- Remove invalid aria-labelledby (text string, not ID) from
  AutoSendPrompt checkbox that is already aria-hidden
- Remove useMemo wrapping trivial `disabled ?? false` in ToolsDropdown
- Remove dead context spread in PromptsAccordion (GroupSidePanel
  reads context internally)
- Wrap search cache-clear effect in requestAnimationFrame to match
  favorites effect pattern in Conversations
- Use Set for O(1) lookups in MCPSelect server filtering
- Fix unnecessary JSX expression wrapper on string literal in
  CreatePromptButton Link

* style(PromptTextCard): update icon classes for improved accessibility

- Add 'text-text-secondary' class to Check and Copy icons for better visibility and consistency in the PromptTextCard component.

🎯 fix: Use Resolved Provider for Agent Token Lookup on Custom Endpoints (#12574)
* fix: Use resolved provider for agent token lookup on custom endpoints

The providerEndpointMap lookup in initializeAgent used the original
provider name (e.g. "EduGPT") instead of the resolved overrideProvider
("openai"). Since providerEndpointMap only contains 4 built-in
providers, custom providers resolved to undefined, causing
getModelMaxTokens to miss the token map and fall back to 18000 tokens.
With agent instructions + tool schemas consuming most of that budget,
createPruneMessages would strip all messages on the first turn.

* fix: Use correct EndpointTokenConfig type in test

* refactor: Unify test factory, remove non-discriminating test

Address review findings:
- Remove Test 2 ("uses the model real context window") which passed
  with and without the fix due to getModelMaxTokens defaulting to
  openAI when endpoint is undefined (JS default parameter semantics)
- Merge createCustomProviderMocks into createMocks via provider,
  overrideProvider, and useRealTokenLookup parameters
- Hoist jest.requireActual to file scope for shared access

* refactor: Address followup review findings

- Replace loose `maxContextTokens > 18000` assertion with precise
  computed value `Math.round((65536 - 4096) * 0.95)` so the outcome
  assertion is meaningful and self-documenting
- Hoist `customProvider` to describe-level constant `CUSTOM_PROVIDER`
- Document `overrideProvider` semantics and `useRealTokenLookup` in
  factory JSDoc
- Add comment on real `optionalChainWithEmptyCheck` noting its
  zero-handling semantics are load-bearing for the maxContextTokens=0
  test

* style: Use // for inline comment, clarify pipeline assertion role

🚫 fix: Hide Delete Account Button When ALLOW_ACCOUNT_DELETION Is Disabled (#12568)
* fix: hide Delete Account button when ALLOW_ACCOUNT_DELETION is false

* fix: add admin bypass, inline env read, and tests for allowAccountDeletion

- Show delete button for admin users even when ALLOW_ACCOUNT_DELETION=false,
  matching the canDeleteAccount middleware's ACCESS_ADMIN bypass
- Move env var read inline in buildSharedPayload() for per-request evaluation
- Add 4 frontend tests for Account conditional rendering
- Add 3 backend tests for allowAccountDeletion config field

* fix: use server-side ACCESS_ADMIN capability check instead of frontend role check

- Replace frontend SystemRoles.ADMIN check with server-side hasCapability()
  in the authenticated config route, matching canDeleteAccount middleware exactly
- Admin bypass now evaluates ACCESS_ADMIN capability per-user in GET /api/config,
  so users with the grant (regardless of role) see the button, and admins
  without the grant do not
- Add 3 authenticated backend tests: without capability, with capability,
  and skip-when-already-enabled
- Simplify frontend to pure config check (no role logic)
- Remove redundant jest-dom import; add inline env var comment

* test: add missing toHaveBeenCalled assertion in ACCESS_ADMIN test

♻️ fix: Reuse Existing MCP OAuth Client Registrations to Prevent client_id Mismatch (#11925)
* fix: reuse existing OAuth client registrations to prevent client_id mismatch

When using auto-discovered OAuth (DCR), LibreChat calls /register on every
flow initiation, getting a new client_id each time. When concurrent
connections or reconnections happen, the client_id used during /authorize
differs from the one used during /token, causing the server to reject the
exchange.

Before registering a new client, check if a valid client registration
already exists in the database and reuse it.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* Handle re-registration of OAuth clients when redirect_uri changes

* Add undefined fields for logo_uri and tos_uri in OAuth metadata tests

* test: add client registration reuse tests for horizontal scaling race condition

Reproduces the client_id mismatch bug that occurs in multi-replica deployments
where concurrent initiateOAuthFlow calls each register a new OAuth client.
Tests verify that the findToken-based client reuse prevents re-registration.

* fix: address review findings for client registration reuse

- Fix empty redirect_uris bug: invert condition so missing/empty
  redirect_uris triggers re-registration instead of silent reuse
- Revert undocumented config?.redirect_uri in auto-discovery path
- Change DB error logging from debug to warn for operator visibility
- Fix import order: move package type import to correct section
- Remove redundant type cast and misleading JSDoc comment
- Test file: remove dead imports, restore process.env.DOMAIN_SERVER,
  rename describe blocks, add empty redirect_uris edge case test,
  add concurrent reconnection test with pre-seeded token,
  scope documentation to reconnection stabilization

* fix: resolve type check errors for OAuthClientInformation redirect_uris

The SDK's OAuthClientInformation type lacks redirect_uris (only on
OAuthClientInformationFull). Cast to the local OAuthClientInformation
type in handler.ts when accessing deserialized client info from DB,
and use intersection types in tests for clientInfo with redirect_uris.

* fix: address follow-up review findings R1, R2, R3

- R1: Move `import type { TokenMethods }` to the type-imports section,
  before local types, per CLAUDE.md import order rules
- R2: Add unit test for empty redirect_uris in handler.test.ts to
  verify the inverted condition triggers re-registration
- R3: Use delete for process.env.DOMAIN_SERVER restoration when the
  original value was undefined to avoid coercion to string "undefined"

* fix: clear stale client registration on OAuth flow failure

When a stored client_id is no longer recognized by the OAuth server,
the flow fails but the stale client stays in MongoDB, causing every
retry to reuse the same invalid registration in an infinite loop.

On OAuth failure, clear the stored client registration so the next
attempt falls through to fresh Dynamic Client Registration.

- Add MCPTokenStorage.deleteClientRegistration() for targeted cleanup
- Call it from MCPConnectionFactory's OAuth failure path
- Add integration test proving recovery from stale client reuse

* fix: validate auth server identity and target cleanup to reused clients

- Gate client reuse on authorization server identity: compare stored
  issuer against freshly discovered metadata before reusing, preventing
  wrong-client reuse when the MCP server switches auth providers
- Add reusedStoredClient flag to MCPOAuthFlowMetadata so cleanup only
  runs when the failed flow actually reused a stored registration,
  not on unrelated failures (timeouts, user-denied consent, etc.)
- Add cleanup in returnOnOAuth path: when a prior flow that reused a
  stored client is detected as failed, clear the stale registration
  before re-initiating
- Add tests for issuer mismatch and reusedStoredClient flag assertions

* fix: address minor review findings N3, N5, N6

- N3: Type deleteClientRegistration param as TokenMethods['deleteTokens']
  instead of Promise<unknown>
- N5: Elevate deletion failure logging from debug to warn for operator
  visibility when stale client cleanup fails
- N6: Use getLogPrefix() instead of hardcoded log prefix to respect
  system-user privacy convention

* fix: correct stale-client cleanup in both OAuth paths

- Blocking path: remove result?.clientInfo guard that made cleanup
  unreachable (handleOAuthRequired returns null on failure, so
  result?.clientInfo was always false in the failure branch)
- returnOnOAuth path: only clear stored client when the prior flow
  status is FAILED, not on COMPLETED or PENDING flows, to avoid
  deleting valid registrations during normal flow replacement

* fix: remove redundant cast on clientMetadata

clientMetadata is already typed as Record<string, unknown>; the
as Record<string, unknown> cast was a no-op.

* fix: thread reusedStoredClient through return type instead of re-reading flow state

FlowStateManager.createFlow() deletes FAILED flow state before
rejecting, so getFlowState() after handleOAuthRequired() returns null
would find nothing — making the stale-client cleanup dead code.

Fix: hoist reusedStoredClient flag from flowMetadata into a local
variable, include it in handleOAuthRequired()'s return type (both
success and catch paths), and use result.reusedStoredClient directly
in the caller instead of a second getFlowState() round-trip.

* fix: selective stale-client cleanup in returnOnOAuth path

The returnOnOAuth cleanup was unreliable: it depended on reading
FAILED flow state, but FlowStateManager.monitorFlow() deletes FAILED
state before rejecting. Move cleanup into createFlow's catch handler
where flowMetadata.reusedStoredClient is still in scope.

Make cleanup selective in both paths: add isClientRejection() helper
that only matches errors indicating the OAuth server rejected the
client_id (invalid_client, unauthorized_client, client not found).
Timeouts, user-cancelled flows, and other transient failures no
longer wipe valid stored registrations.

Thread the error from handleOAuthRequired() through the return type
so the blocking path can also check isClientRejection().

* fix: tighten isClientRejection heuristic

Narrow 'client_id' match to 'client_id mismatch' to avoid
false-positive cleanup on unrelated errors that happen to
mention client_id.

* test: add isClientRejection tests and enforced client_id on test server

- Add isClientRejection unit tests: invalid_client, unauthorized_client,
  client_id mismatch, client not found, unknown client, and negative
  cases (timeout, flow state not found, user denied, null, undefined)
- Enhance OAuth test server with enforceClientId option: binds auth
  codes to the client_id that initiated /authorize, rejects token
  exchange with mismatched or unregistered client_id (401 invalid_client)
- Add integration tests proving the test server correctly rejects
  stale client_ids and accepts matching ones at /token

* fix: issuer validation, callback error propagation, and cleanup DRY

- Issuer check: re-register when storedIssuer is absent or non-string
  instead of silently reusing. Narrows unknown type with typeof guard
  and inverts condition so missing issuer → fresh DCR (safer default).
- OAuth callback route: call failFlow with the OAuth error when the
  authorization server redirects back with error= parameter, so the
  waiting flow receives the actual rejection instead of timing out.
  This lets isClientRejection match stale-client errors correctly.
- Extract duplicated cleanup block to clearStaleClientIfRejected()
  private method, called from both returnOnOAuth and blocking paths.
- Test fixes: add issuer to stored metadata in reuse tests, reset
  server to undefined in afterEach to prevent double-close.

* fix: gate failFlow behind callback validation, propagate reusedStoredClient on join

- OAuth callback: move failFlow call to after CSRF/session/active-flow
  validation so an attacker with only a leaked state parameter cannot
  force-fail a flow without passing the same integrity checks required
  for legitimate callbacks
- PENDING join path: propagate reusedStoredClient from flow metadata
  into the return object so joiners can trigger stale-client cleanup
  if the joined flow later fails with a client rejection

* fix: restore early oauthError/code redirects, gate only failFlow behind CSRF

The previous restructuring moved oauthError and missing-code checks
behind CSRF validation, breaking tests that expect those redirects
without cookies. The redirect itself is harmless (just shows an error
page). Only the failFlow call needs CSRF gating to prevent DoS.

Restructure: oauthError check stays early (redirects immediately),
but failFlow inside it runs the full CSRF/session/active-flow
validation before marking the flow as FAILED.

* fix: require deleteTokens for client reuse, add missing import in MCP.js

Client registration reuse without cleanup capability creates a
permanent failure loop: if the reused client is stale, the code
detects the rejection but cannot clear the stored registration
because deleteTokens is missing, so every retry reuses the same
broken client_id.

- MCPConnectionFactory: only pass findToken to initiateOAuthFlow
  when deleteTokens is also available, ensuring reuse is only
  enabled when recovery is possible
- api/server/services/MCP.js: add deleteTokens to the tokenMethods
  object (was the only MCP call site missing it)

* fix: set reusedStoredClient before createFlow in joined-flow path

When joining a PENDING flow, reusedStoredClient was only set on the
success return but not before the await. If createFlow throws (e.g.
invalid_client during token exchange), the outer catch returns the
local variable which was still false, skipping stale-client cleanup.

* fix: require browser binding (CSRF/session) for failFlow on OAuth error

hasActiveFlow only proves a PENDING flow exists, not that the caller
is the same browser that initiated it. An attacker with a leaked state
could force-fail the flow without any user binding. Require hasCsrf or
hasSession before calling failFlow on the oauthError path.

* fix: guard findToken with deleteTokens check in blocking OAuth path

Match the returnOnOAuth path's defense-in-depth: only enable client
registration reuse when deleteTokens is also available, ensuring
cleanup is possible if the reused client turns out to be stale.

* fix: address review findings — tests, types, normalization, docs

- Add deleteTokens method to InMemoryTokenStore matching TokenMethods
  contract; update test call site from deleteToken to deleteTokens
- Add MCPConnectionFactory test: returnOnOAuth flow fails with
  invalid_client → clearStaleClientIfRejected invoked automatically
- Add mcp.spec.js tests: OAuth error with CSRF → failFlow called;
  OAuth error without cookies → failFlow NOT called (DoS prevention)
- Add JSDoc to isClientRejection with RFC 6749 and vendor attribution
- Add inline comment explaining findToken/deleteTokens coupling guard
- Normalize issuer comparison: strip trailing slashes to prevent
  spurious re-registrations from URL formatting differences
- Fix dead-code: use local reusedStoredClient variable in PENDING
  join return instead of re-reading flowMeta

* fix: address final review nits N1-N4

- N1: Add session cookie failFlow test — validates the hasSession
  branch triggers failFlow on OAuth error callback
- N2: Replace setTimeout(50) with setImmediate for microtask drain
- N3: Add 'unknown client' attribution to isClientRejection JSDoc
- N4: Remove dead getFlowState mock from failFlow tests

🔎 fix: Specify Explicit Primary Key for Meilisearch Document Operations (#12542)
* fix: pass explicit primaryKey to Meilisearch addDocuments/updateDocuments calls

Meilisearch v1.0+ refuses to auto-infer the primary key when a document
contains multiple fields ending with 'id'. The messages index has both
conversationId and messageId, causing addDocuments to silently fail with
index_primary_key_multiple_candidates_found, leaving message search empty.

Pass { primaryKey } to addDocumentsInBatches, addDocuments, and
updateDocuments — the variable was already in scope.

Also replace raw this.collection.updateMany with Mongoose Model.updateMany
to satisfy the no-restricted-syntax ESLint rule (tenant isolation guard).

Closes #12538

* fix: resolve additional Meilisearch plugin bugs found in review

Address review findings from PR #12542:

- Fix deleteObjectFromMeili using MongoDB _id instead of the Meilisearch
  primary key (conversationId/messageId), causing post-remove cleanup to
  silently no-op and leave orphaned documents in the index.

- Pass options.primaryKey explicitly to createMeiliMongooseModel factory
  instead of deriving it from attributesToIndex[0] (schema field order),
  eliminating a fragile implicit contract.

- Fix updateObjectToMeili skipping preprocessObjectForIndex, which meant
  updates bypassed content array-to-text conversion and conversationId
  pipe character escaping.

- Change collection.updateMany to collection.updateOne in addObjectToMeili
  since _id is unique (semantic correctness).

- Add primaryKey to validateOptions required keys.

- Strengthen test assertions to verify { primaryKey } argument is passed
  to addDocuments, addDocumentsInBatches, and updateDocuments. Add tests
  for the update path including preprocessObjectForIndex pipe escaping.

* fix: add regression tests for delete and message update paths

Address follow-up review findings:

- Add test for deleteObjectFromMeili verifying it uses messageId (not
  MongoDB _id) when calling index.deleteDocument, guarding against
  regression of the silent orphaned-document bug.

- Add test for message model update path asserting { primaryKey:
  'messageId' } is passed to updateDocuments (previously only the
  conversation model update path was tested).

- Add @param config.primaryKey to createMeiliMongooseModel JSDoc.

📦 chore: Bump mongodb-memory-server to v11.0.1, mermaid to v11.14.0, npm audit (#12543)
* 🔧 chore: Update `mongodb-memory-server` to v11.0.1

- Bump `mongodb-memory-server` version in `package-lock.json`, `api/package.json`, and `packages/data-schemas/package.json` from 10.1.4 to 11.0.1.
- Update related dependencies in `mongodb-memory-server` and `mongodb-memory-server-core` to ensure compatibility with the new version.
- Adjust `tslib` version in `mongodb-memory-server` to 2.8.1 and `debug` to 4.4.3 for consistency.

* chore: npm audit fix

* chore: Update `mermaid` dependency to version 11.14.0 in `package-lock.json` and `client/package.json`

* fix: use deterministic timestamps in convoStructure test

MongoDB 8.x (from mongodb-memory-server v11) no longer guarantees
insertion-order return for documents with identical timestamps.
Use sequential timestamps with overrideTimestamp to ensure buildTree
processes parents before children.

🔨 fix: Custom Role Permissions (#12528)
* fix: Resolve custom role permissions not loading in frontend

Users assigned to custom roles (non-USER/ADMIN) had all permission
checks fail because AuthContext only fetched system role permissions.
The roles map keyed by USER/ADMIN never contained the custom role name,
so useHasAccess returned false for every feature gate.

- Fetch the user's custom role in AuthContext and include it in the
  roles map so useHasAccess can resolve permissions correctly
- Use encodeURIComponent instead of toLowerCase for role name URLs
  to preserve custom role casing through the API roundtrip
- Only uppercase system role names on the backend GET route; pass
  custom role names through as-is for exact DB lookup
- Allow users to fetch their own assigned role without READ_ROLES
  capability

* refactor: Normalize all role names to uppercase

Custom role names were stored in original casing, causing case-sensitivity
bugs across the stack — URL lowercasing, route uppercasing, and
case-sensitive DB lookups all conflicted for mixed-case custom roles.

Enforce uppercase normalization at every boundary:
- createRoleByName trims and uppercases the name before storage
- createRoleHandler uppercases before passing to createRoleByName
- All admin route handlers (get, update, delete, members, permissions)
  uppercase the :name URL param before DB lookups
- addRoleMemberHandler uppercases before setting user.role
- Startup migration (normalizeRoleNames) finds non-uppercase custom
  roles, renames them, and updates affected user.role values with
  collision detection

Legacy GET /api/roles/:roleName retains always-uppercase behavior.
Tests updated to expect uppercase role names throughout.

* fix: Use case-preserved role names with strict equality

Remove uppercase normalization — custom role names are stored and
compared exactly as the user sets them, with only trimming applied.
USER and ADMIN remain reserved case-insensitively via isSystemRoleName.

- Remove toUpperCase from createRoleByName, createRoleHandler, and
  all admin route handlers (get, update, delete, members, permissions)
- Remove toUpperCase from legacy GET and PUT routes in roles.js;
  the frontend now sends exact casing via encodeURIComponent
- Remove normalizeRoleNames startup migration
- Revert test expectations to original casing

* fix: Format useMemo dependency array for Prettier

* feat: Add custom role support to admin settings + review fixes

- Add backend tests for isOwnRole authorization gate on GET /api/roles/:roleName
- Add frontend tests for custom role detection and fetching in AuthContext
- Fix transient null permission flash by only spreading custom role once loaded
- Add isSystemRoleName helper to data-provider for case-insensitive system role detection
- Use sentinel value in useGetRole to avoid ghost cache entry from empty string
- Add useListRoles hook and listRoles data service for fetching all roles
- Update AdminSettingsDialog and PeoplePickerAdminSettings to dynamically
  list custom roles in the role dropdown, with proper fallback defaults

* fix: Address review findings for custom role permissions

- Add assertions to AuthContext test verifying custom role in roles map
- Fix empty array bypassing nullish coalescing fallback in role dropdowns
- Add null/undefined guard to isSystemRoleName helper
- Memoize role dropdown items to avoid unnecessary re-renders
- Apply sentinel pattern to useGetRole in admin settings for consistency
- Mark ListRolesResponse description as required to match schema

* fix: Prevent prototype pollution in role authorization gate

- Replace roleDefaults[roleName] with Object.hasOwn to prevent
  prototype chain bypass for names like constructor or __proto__
- Add dedicated rolesList query key to avoid cache collision when
  a custom role is named 'list'
- Add regression test for prototype property name authorization

* fix: Resolve Prettier formatting and unused variable lint errors

* fix: Address review findings for custom role permissions

- Add ADMIN self-read test documenting isOwnRole bypass behavior
- Guard save button while custom role data loads to prevent data loss
- Extract useRoleSelector hook eliminating ~55 lines of duplication
- Unify defaultValues/useEffect permission resolution (fixes inconsistency)
- Make ListRolesResponse.description and _id optional to match schema
- Fix vacuous test assertions to verify sentinel calls exist
- Only fetch userRole when user.role === USER (avoid unnecessary requests)
- Remove redundant empty string guard in custom role detection

* fix: Revert USER role fetch restriction to preserve admin settings

Admins need the USER role loaded in AuthContext.roles so the admin
settings dialog shows persisted USER permissions instead of defaults.

* fix: Remove unused useEffect import from useRoleSelector

* fix: Clean up useRoleSelector hook

- Use existing isCustom variable instead of re-calling isSystemRoleName
- Remove unused roles and availableRoleNames from return object

* fix: Address review findings for custom role permissions

- Use Set-based isSystemRoleName to auto-expand with future SystemRoles
- Add isCustomRoleError handling: guard useEffect reset and disable Save
- Remove resolvePermissions from hook return; use defaultValues in useEffect
  to eliminate redundant computation and stale-closure reset race
- Rename customRoleName to userRoleName in AuthContext for clarity

* fix: Request server-max roles for admin dropdown

listRoles now passes limit=200 (the server's MAX_PAGE_LIMIT) so the
admin role selector shows all roles instead of silently truncating
at the default page size of 50.

🔐 fix: Strip code_challenge from Admin OAuth requests before Passport (#12534)
* 🔐 fix: Strip code_challenge from admin OAuth requests before Passport

openid-client v6's Passport Strategy uses `currentUrl.searchParams.size === 0`
to distinguish initial authorization requests from OAuth callbacks. The
admin-panel-specific `code_challenge` query parameter caused the strategy to
misclassify the request as a callback and return 401 Unauthorized.

* 🔐 fix: Strip code_challenge from admin OAuth requests before Passport

openid-client v6's Passport Strategy uses `currentUrl.searchParams.size === 0`
to distinguish initial authorization requests from OAuth callbacks. The
admin-panel-specific `code_challenge` query parameter caused the strategy to
misclassify the request as a callback and return 401 Unauthorized.

- Fix regex to handle `code_challenge` in any query position without producing
  malformed URLs, and handle empty `code_challenge=` values (`[^&]*` vs `[^&]+`)
- Combine `storePkceChallenge` + `stripCodeChallenge` into a single
  `storeAndStripChallenge` helper to enforce read-store-strip ordering
- Apply defensively to all 7 admin OAuth providers
- Add 12 unit tests covering stripCodeChallenge and storeAndStripChallenge

* refactor: Extract PKCE helpers to utility file, harden tests

- Move stripCodeChallenge and storeAndStripChallenge to
  api/server/utils/adminPkce.js — eliminates _test production export
  and avoids loading the full auth.js module tree in tests
- Add missing req.originalUrl/req.url assertions to invalid-challenge
  and no-challenge test branches (regression blind spots)
- Hoist cache reference to module scope in tests (was redundantly
  re-acquired from mock factory on every beforeEach)

* chore: Address review NITs — imports, exports, naming, assertions

- Fix import order in auth.js (longest-to-shortest per CLAUDE.md)
- Remove unused PKCE_CHALLENGE_TTL/PKCE_CHALLENGE_PATTERN exports
- Hoist strip arrow to module-scope stripChallengeFromUrl
- Rename auth.test.js → auth.spec.js (project convention)
- Tighten cache-failure test: toBe instead of toContain, add req.url

* refactor: Move PKCE helpers to packages/api with dependency injection

Move stripCodeChallenge and storeAndStripChallenge from api/server/utils
into packages/api/src/auth/exchange.ts alongside the existing PKCE
verification logic. Cache is now injected as a Keyv parameter, matching
the dependency-injection pattern used throughout packages/api/.

- Add PkceStrippableRequest interface for minimal req typing
- auth.js imports storeAndStripChallenge from @librechat/api
- Delete api/server/utils/adminPkce.js
- Move tests to packages/api/src/auth/adminPkce.spec.ts (TypeScript,
  real Keyv instances, no getLogStores mock needed)

📎 fix: Route Unrecognized File Types via supportedMimeTypes Config (#12508)
* fix: check supportedMimeTypes before routing unrecognized file types

In processAttachments, files not matching the hardcoded mime type
categories (image, PDF, video, audio) were silently dropped. Now
resolves the endpoint's file config and checks the file type against
supportedMimeTypes before routing to the documents pipeline. Files
not matching any config are still skipped (original behavior).

Closes #12482

* feat: encode generic document types for supported providers

Remove restrictive mime type filter in encodeAndFormatDocuments that
only allowed PDFs and application/* types. Add a generic encoding
path for non-PDF, non-Bedrock files using the provider's native
format (Anthropic base64 document, OpenAI file block, Google media
block). Files are already validated upstream by supportedMimeTypes.

* fix: guard file.type and cache file config in processAttachments

- Add file.type truthiness check before checkType to prevent
  coercion of null/undefined to string 'null'/'undefined'
- Cache mergedFileConfig and endpointFileConfig on the instance
  so addPreviousAttachments doesn't recompute per message

* refactor: harden generic document encoding with validation and tests

- Extract formatDocumentBlock helper to eliminate ~30 lines of
  duplicate provider-dispatch code between PDF and generic paths
- Add size validation in generic encoding path using
  configuredFileSizeLimit (was fetched but unused)
- Guard Bedrock from generic path — non-bedrockDocumentFormats
  types are now skipped instead of silently tracking metadata
- Only push metadata to result.files when a document block was
  actually created, preventing silent inconsistent state
- Enable Anthropic citations for text/plain, text/html,
  text/markdown (supported by Anthropic's document API)
- Fix != to !== for Providers.AZURE comparison
- Add 9 tests covering all four provider branches, Bedrock
  exclusion, size limit enforcement, and unhandled provider

* fix: resolve filename type mismatch in formatDocumentBlock

filename parameter is string | undefined but OpenAIFileBlock and
OpenAIInputFileBlock require string. Default to 'document' when
filename is undefined.

* fix: use endpoint name for file config lookup in processAttachments

Agent runs can have agent.provider set to a base provider (e.g.,
openAI) while agent.endpoint is a custom endpoint name. Using
provider for the getEndpointFileConfig lookup bypassed custom
endpoint supportedMimeTypes config. Now uses agent.endpoint,
matching the pattern in addDocuments.

* perf: filter non-Bedrock files before fetching streams

Bedrock only supports types in bedrockDocumentFormats. Previously,
getFileStream was called for all files and unsupported types were
discarded after download. Now pre-filters the file list for Bedrock
to avoid unnecessary network and memory overhead for large
unsupported attachments.

* refactor: clean up processAttachments file config handling

- Remove redundant ?? null intermediaries; use instance properties
  directly in the else-if condition
- Add JSDoc @type annotations for _mergedFileConfig and
  _endpointFileConfig in the constructor

* refactor: harden document encoding and add routing tests

- Hoist configuredFileSizeLimit above the loop to avoid recomputing
  mergeFileConfig per file
- Replace Buffer.from decode with base64 length formula in the
  generic size check to avoid unnecessary heap allocation
- Use nullish coalescing (??) for filename fallback
- Clean up test: remove unnecessary type cast, use createMockRequest
  helper for size-limit test
- Add 14 tests for processAttachments categorization logic covering
  supportedMimeTypes routing, null/undefined guards, standard type
  passthrough, and edge cases

* fix: use optional chaining for checkType in routing tests

FileConfig.checkType is typed as optional. Use optional chaining
to satisfy strict type checking.

* fix: skip stream fetches for unsupported providers, block Bedrock generic routing

- Return early from encodeAndFormatDocuments when the provider is
  neither document-supported nor Bedrock, avoiding unnecessary
  getFileStream calls for providers that would discard all results
- Add !isBedrock guard to the supportedMimeTypes fallback branch in
  processAttachments so permissive patterns like '.*' don't route
  non-Bedrock types into documents that would be silently dropped
- Add test for Bedrock + non-Bedrock-document-type skipping

* fix: respect supportedMimeTypes config for Bedrock endpoints

Remove !isBedrock guard from the generic supportedMimeTypes routing
branch. If a user configures permissive supportedMimeTypes for a
Bedrock endpoint, the upload validation already accepted the file.
The encoding layer pre-filters to Bedrock-supported types before
fetching streams, so unsupported types are handled there without
silently dropping files the user explicitly allowed.

🎯 fix: MCP Tool Misclassification from Action Delimiter Collision (#12512)
* fix: prevent MCP tools with `_action` in name from being misclassified as OpenAPI action tools

Add `isActionTool()` helper that checks for the `_action_` delimiter
while guarding against cross-delimiter collision with `_mcp_`. Replace
all `includes(actionDelimiter)` classification checks with the new
helper across backend and frontend.

* test: add coverage for MCP/action cross-delimiter collision

Verify that `isActionTool` correctly rejects MCP tool names containing
`_action` and that `loadAgentTools` does not filter them based on
`actionsEnabled`. Add ToolIcon and definitions test cases.

* fix: simplify isActionTool to handle all MCP name patterns

- Use `!toolName.includes('_mcp_')` instead of checking only after the
  first `_action_` occurrence, which missed MCP tools with `_action_` in
  the middle of their name (e.g. `get_action_data_mcp_myserver`).
- Reference `Constants.mcp_delimiter` value via a local const to avoid
  circular import from config.ts, with a comment explaining why.
- Remove dead `actionDelimiter` import from definitions.ts.
- Replace double-filter with single-pass partition in loadToolsForExecution.
- Add test for mid-name `_action_` collision case.

* fix: narrow MCP exclusion to delimiter position in isActionTool

Only reject when `_mcp_` appears after `_action_` (the MCP suffix
position). `_mcp_` before `_action_` is part of the operationId and
is valid — e.g. `sync_mcp_state_action_api---example---com` is a
legitimate action tool whose operationId happens to contain `_mcp_`.

* fix: document positional _mcp_ guard and known RFC-invalid domain limitation

Expand JSDoc on isActionTool to explain the action/MCP format
disambiguation and the theoretical false negative for non-RFC-compliant
domains containing `_mcp_`. Add test documenting this known edge case.

🔁 fix: Pass recursionLimit to OpenAI-Compatible Agents API Endpoint (#12510)
* fix: pass recursionLimit to processStream in OpenAI-compatible agents API

The OpenAI-compatible endpoint never passed recursionLimit to LangGraph's
processStream(), silently capping all API-based agent calls at the default
25 steps. Mirror the 3-step cascade already used by the UI path (client.js):
yaml config default → per-agent DB override → max cap.

* refactor: extract resolveRecursionLimit into shared utility

Extract the 3-step recursion limit cascade into a shared
resolveRecursionLimit() function in @librechat/api. Both openai.js and
client.js now call this single source of truth.

Also fixes falsy-guard edge cases where recursion_limit=0 or
maxRecursionLimit=0 would silently misbehave, by using explicit
typeof + positive checks.

Includes unit tests covering all cascade branches and edge cases.

* refactor: use resolveRecursionLimit in openai.js and client.js

Replace duplicated cascade logic in both controllers with the shared
resolveRecursionLimit() utility from @librechat/api.

In openai.js: hoist agentsEConfig to avoid double property walk,
remove displaced comment, add integration test assertions.

In client.js: remove inline cascade that was overriding config
after initial assignment.

* fix: hoist processStream mock for test accessibility

The processStream mock was created inline inside mockResolvedValue,
making it inaccessible via createRun.mock.results (which returns
the Promise, not the resolved value). Hoist it to a module-level
variable so tests can assert on it directly.

* test: improve test isolation and boundary coverage

Use mockReturnValueOnce instead of mockReturnValue to prevent mock
leaking across test boundaries. Add boundary tests for downward
agent override and exact-match maxRecursionLimit.

🛡️ refactor: Self-Healing Tenant Isolation Update Guard (#12506)
* refactor: self-healing tenant isolation update guard

Replace the strict throw-on-any-tenantId guard with a
strip-or-throw approach:

- $set/$setOnInsert: strip when value matches current tenant
  or no context is active; throw only on cross-tenant mutations
- $unset/$rename: always strip (unsetting/renaming tenantId
  is never valid)
- Top-level tenantId: same logic as $set

This eliminates the entire class of "tenantId in update payload"
bugs at the plugin level while preserving the cross-tenant
security invariant.

* test: update mutation guard tests for self-healing behavior

- Convert same-tenant $set/$setOnInsert tests to expect silent
  stripping instead of throws
- Convert $unset test to expect silent stripping
- Add cross-tenant throw tests for $set, $setOnInsert, top-level
- Add same-tenant stripping tests for $set, $setOnInsert, top-level
- Add $rename stripping test
- Add no-context stripping test
- Update error message assertions to match new cross-tenant message

* revert: remove call-site tenantId stripping patches

Revert the per-call-site tenantId stripping from #12498 and
the excludedKeys patch from #12501. These are no longer needed
since the self-healing guard handles tenantId in update payloads
at the plugin level.

Reverted patches:
- conversation.ts: delete update.tenantId in saveConvo(),
  tenantId destructuring in bulkSaveConvos()
- message.ts: delete update.tenantId in saveMessage() and
  recordMessage(), tenantId destructuring in bulkSaveMessages()
  and updateMessage()
- config.ts: tenantId in excludedKeys Set
- config.spec.ts: tenantId in excludedKeys test assertion

* fix: strip tenantId from update documents in tenantSafeBulkWrite

Mongoose middleware does not fire for bulkWrite, so the plugin-level
guard never sees update payloads in bulk operations. Extend
injectTenantId() to strip tenantId from update documents for
updateOne/updateMany operations, preventing cross-tenant overwrites.

* refactor: rename guard, add empty-op cleanup and strict-mode warning

- Rename assertNoTenantIdMutation to sanitizeTenantIdMutation
- Remove empty operator objects after stripping to avoid MongoDB errors
- Log warning in strict mode when stripping tenantId without context
- Fix $setOnInsert test to use upsert:true with non-matching filter

* test: fix bulk-save tests and add negative excludedKeys assertion

- Wrap bulkSaveConvos/bulkSaveMessages tests in tenantStorage.run()
  to exercise the actual multi-tenant stripping path
- Assert tenantId equals the real tenant, not undefined
- Add negative assertion: excludedKeys must NOT contain tenantId

* fix: type-safe tenantId stripping in tenantSafeBulkWrite

- Fix TS2345 error: replace conditional type inference with
  UpdateQuery<Record<string, unknown>> for stripTenantIdFromUpdate
- Handle empty updates after stripping (e.g., $set: { tenantId } as
  sole field) by filtering null ops from the bulk array
- Add 4 tests for bulk update tenantId stripping: plain-object update,
  $set stripping, $unset stripping, and sole-field-in-$set edge case

* fix: resolve TS2345 in stripTenantIdFromUpdate parameter type

Use Record<string, unknown> instead of UpdateQuery<> to avoid
type incompatibility with Mongoose's AnyObject-based UpdateQuery
resolution in CI.

* fix: strip tenantId from bulk updates unconditionally

Separate sanitization from injection in tenantSafeBulkWrite:
tenantId is now stripped from all update documents before any
tenant-context checks, closing the gap where no-context and
system-context paths passed caller-supplied tenantId through
to MongoDB unmodified.

* refactor: address review findings in tenant isolation

- Fix early-return gap in stripTenantIdFromUpdate that skipped
  operator-level tenantId when top-level was also present
- Lazy-allocate copy in stripTenantIdFromUpdate (no allocation
  when no tenantId is present)
- Document behavioral asymmetry: plugin throws on cross-tenant,
  bulkWrite strips silently (intentional, documented in JSDoc)
- Remove double JSDoc on injectTenantId
- Remove redundant cast in stripTenantIdFromUpdate
- Use shared frozen EMPTY_BULK_RESULT constant
- Remove Record<string, unknown> annotation in recordMessage
- Isolate bulkSave* tests: pre-create docs then update with
  cross-tenant payload, read via runAsSystem to prove stripping
  is independent of filter injection

* fix: no-op empty updates after tenantId sanitization

When tenantId is the sole field in an update (e.g., { $set: { tenantId } }),
sanitization leaves an empty update object that would fail with
"Update document requires atomic operators." The updateGuard now
detects this and short-circuits the query by adding an unmatchable
filter condition and disabling upsert, matching the bulk-write
handling that filters out null ops.

* refactor: remove dead logger.warn branches, add mixed-case test

- Remove unreachable logger.warn calls in sanitizeTenantIdMutation:
  queryMiddleware throws before updateGuard in strict+no-context,
  and isStrict() is false in non-strict+no-context
- Add test for combined top-level + operator-level tenantId stripping
  to lock in the early-return fix

* feat: ESLint rule to ban raw bulkWrite and collection.* in data-schemas

Add no-restricted-syntax rules to the data-schemas ESLint config that
flag direct Model.bulkWrite() and Model.collection.* calls. These
bypass Mongoose middleware and the tenant isolation plugin — all bulk
writes must use tenantSafeBulkWrite() instead.

Test files are excluded since they intentionally use raw driver calls
for fixture setup.

Also migrate the one remaining raw bulkWrite in seedSystemGrants() to
use tenantSafeBulkWrite() for consistency.

* test: add findByIdAndUpdate coverage to mutation guard tests

* fix: keep tenantSafeBulkWrite in seedSystemGrants, fix ESLint config

- Revert to tenantSafeBulkWrite in seedSystemGrants (always runs
  under runAsSystem, so the wrapper passes through correctly)
- Split data-schemas ESLint config: shared TS rules for all files,
  no-restricted-syntax only for production non-wrapper files
- Fix unused destructure vars to use _tenantId pattern
