The built-in chat and knowledge grep tools awaited their matching helper directly, so the search ran on the event loop and held it for as long as the match took. Both call sites now hand the helper to a worker thread.
Output and error handling are unchanged: 17 cases (literal, regex, case-insensitive, count-only, no-match, invalid pattern, rejected quantifiers, missing file data, result truncation) compare byte-for-byte against the previous behaviour. The matcher's time budget lives in a contextvar, which asyncio.to_thread copies into the worker, so budget scoping still behaves as before.
* fix: preserve user info in agentic RAG tools
* fix: preserve user info in file access checks

The `create_automation` and `update_automation` builtin tools wrote straight to `Automations.insert` / `Automations.update_by_id`, skipping the limit checks that `/api/v1/automations/create` and `/api/v1/automations/{id}/update` run through `check_automation_limits`. A non-admin user could therefore ask the model to create automations indefinitely, ignoring `AUTOMATION_MAX_COUNT`, and could schedule them below `AUTOMATION_MIN_INTERVAL`, on both create and update.
Both tools now call the same `check_automation_limits` helper the routers use, so the limits and the admin bypass cannot drift between the chat path and the HTTP path. A rejection is returned to the model as a plain error message instead of raising. `update_automation` also gained the missing user lookup guard, since the helper needs the user's role.
The `automations.enable` toggle and the `features.automations` user permission were already enforced when the tool set is assembled, so they are unaffected.
Fixes#27121
When called without attached model knowledge and given a caller-supplied knowledge_id, search_knowledge_files passed it straight to Knowledges.search_files_by_id, which does not enforce ownership on knowledge_id. An authenticated user who happened to know a target UUID could enumerate file metadata (filename, file id, KB id, KB name, updated_at) from any knowledge base, bypassing the AccessGrants permission model.
Mirror the same admin/owner/AccessGrants check the attached-KB branch already uses, matching the sibling query_knowledge_files function.
