 RAG is available as a beta preview feature. Architecture:
 - **External Retrieval Interface (ERI)** - Contract for integrating external data sources
 - **Data Sources** - Local files and external data via ERI servers
- **Two ways to search** - By default, the chat model searches the data sources itself through the tool `semantic_search`, whenever a question calls for it. The classic process (`AISrcSelWithRetCtxVal`) searches them with every message instead, when the user chose so per chat (`DataSourceOptions.RetrievalMode`) or whenever the tool cannot be offered. `ToolRegistry.GetEffectiveRetrievalModeAsync` decides between the two; pass its answer to `DataSourceService`, because the agents only count as providers that see the data when they actually run. See "Searching Data Sources" in `documentation/Tools.md`.

Both ways decide where a chat may still send data once their passages reached it through `DataSourceRequirements.Of`, never with a check of their own: a way which demands less leaves the other one open. See "Searching Data Sources" in `documentation/Tools.md`.
 - **Agents** - AI agents select data sources and validate retrieval quality, in the classic process only
 - **Embedding providers** - Support for various embedding models
 - **Vector database** - Qdrant Edge, embedded in the Rust runtime; see "Databases" below

 - Added backups of all your data. Under Data Backup & Restore, on the information page and in the settings, you save your chats, settings, plugins, and the index of your data sources into a single file, for example, to take everything to a new computer. Restoring such a backup replaces your data when AI Studio restarts, or you add only its chats to the ones you have. API keys and passwords never go into a backup, and after a restore, AI Studio tells you where to enter them again. Thanks, Jens Erler (`j-erler`), for this contribution.
 - Added organization-wide management for backups. IT departments can prevent users from backing up their data or from restoring a backup. A backup leaves out what the configurations of your organization bring along, such as their providers and plugins, so nothing appears twice after a restore.
 - Added an overview of the data folders of AI Studio to the information page, for when you back up your computer with a tool of your own. It shows where the folders are and which of their contents belong into a backup. AI Studio now stores the locations of its own files, such as transcripts, relative to its data folder, so such a copy also works on a computer with another user name.
- Added organization-wide management for where a chat may send data after it has read internal content, such as a page in your intranet or in your Confluence wiki. IT departments can set this, either fixed or as a default which users may change.
+- Added organization-wide management for where a chat may send data after it has read internal content, such as a page in your intranet or in your Confluence wiki. IT departments can set this, either fixed or as a default which users may change. For your data sources, they can rule out the less strict choices.
 - Added a way to import providers, profiles, chat templates, external data sources (ERI servers), and document analysis policies which somebody exported from AI Studio, for example, a colleague who wants to share a chat template with you. The new Import button next to the Add button lets you paste the exported configuration. AI Studio only reads the pasted values and never runs the pasted text, and what you import becomes your own, so you can change it like anything you added yourself. Thanks, Peer Hogeterp (`peerschuett`), for this contribution.
 - Added hints when you import a configuration which somebody exported from AI Studio, for example, when it preselects a provider or a tool which does not exist on your computer, or when a chat template would attach files from your computer to every chat. You decide whether to continue.
 - Added a way to relink or remove the file attachments which are missing on your computer when you import a chat template which somebody exported from AI Studio.

 - Fixed a security issue with external data sources (ERI servers) whose server does not allow any AI provider. AI Studio now follows this rule for self-hosted providers and for providers your organization trusts as well.
 - Fixed the Search Confluence tool missing pages that the search of your Confluence wiki finds. The tool now searches the same way as the search box of your wiki.
 - Fixed a security issue in the Search Confluence and Read Web Page tools. Once the AI has searched your Confluence wiki or read a page in your intranet or behind a VPN, the chat no longer searches the web, and the tool selection tells you why. In the settings of the Read Web Page tool, you decide which web pages such a chat may still read.
+- Fixed a security issue when AI Studio searches your data sources. Once it has found something in a data source, the chat no longer searches the web, and the tool selection tells you why. In the settings of each data source, you decide where such a chat may still send data. If you chose to search your data sources with every message, the web search ends with the first message that finds something.
 - Fixed AI Studio starting only partly when the configuration of your organization took a while to apply. The plugins late in line never started, so the app stayed in English instead of your language, and the configuration of your organization was missing, together with its models and its welcome text. Now every plugin gets its own time to start, and a slow one no longer holds up the others.
 - Fixed AI Studio deleting the providers, chat templates, and profiles of your organization, including their API keys, when the configuration of your organization did not start in time. They now stay in place until the configuration starts again.
 - Fixed saving the settings taking about 20 seconds each time when a chat template had an attachment on a network drive that was out of reach. Since AI Studio saves its settings while starting, this also slowed down every start.

+## Where a chat may send data after searching data sources
+
+The AI searches the data sources of a chat, local files and folders as well as external data sources (ERI servers), either itself through Semantic Search or with every message. Each data source decides where a chat may still send data once the AI found something in it, with the same levels as a mailbox, see [Where a chat may send data](#where-a-chat-may-send-data). New data sources start with `ONLY_LINKS_FROM_CHAT`, and so do the ones users added before the setting existed. An external data source whose security policy is `SELF_HOSTED` always gets `ONLY_CONFIGURED_SERVICES`, since its data must not leave your infrastructure through a tool either. Your Confluence wiki and the hosts in `read_web_page.allowedPrivateHosts` stay readable on that level, so the links of such a data source into your intranet still work, while a link to a public page does not.

+|---|---|
+| `DataSourceSecuritySettings.MinimumOutboundDataRestriction` | The least strict level a data source may have. A data source set to a less strict one gets your level whenever its passages reach a chat, and its dialog no longer offers the less strict levels. |
+| `OutboundDataRestriction` in an entry of `CONFIG["DATA_SOURCES"]` | The level of an external data source your configuration provides.

 **Why an address counts as sending data.** A model which writes an address can put anything it read into it, in the path or the query, and the server at that address receives it. This is why `read_web_page` declares `ToolOutboundData.MODEL_CHOSEN_ADDRESSES` and keeps to the restriction itself, see `ReadWebPageTool.IsAllowedByOutboundDataRestriction`. An address given in the chat, by the user or in the result of a tool, is read word for word, so it carries nothing the model chose.

 A call has to pass both the restriction and the free address choice, so with the choice switched off, a page of the wiki or of an allowed host counts only when its address was given to the model, e.g., as a hit of a wiki search. The instructions of `read_web_page` name what is left on the level of the chat, and a refusal never repeats the address.

-**The order of the tools.** A chat which still may search the web loses that as soon as internal content enters it. Only the tool which brings such content in knows when it does, so `search_mails`, `search_confluence`, and `read_web_page` each tell the model so in their own instructions, and tell it to search the web first when a task needs both. `WebSearchFirstRule` words that rule once for all of them; `search_mails` speaks for the whole mailbox collection, which is always offered together. The tools word their instructions per request and leave the rule out when the request does not offer `web_search`, because a rule about a tool the model does not get would only confuse it. They learn this from `ToolResolutionContext.CandidateToolIds`, the tools which passed every check of the request, which `ToolRegistry.GetRunnableToolsAsync` fills before it asks the first tool what it offers. `search_confluence` also leaves the rule out when the level of internal pages is `UNRESTRICTED`, and `read_web_page` also without a wiki and without allowed private hosts, because it cannot reach an internal page then. A mailbox may have any level, so `search_mails` says that reading it may end the web search. Once the search is gone, no instruction mentions it any more: a call of `web_search` in the same request is refused with the text of `OutboundDataRequirementExtensions.GetToolBlockedMessage`, which names the source and says that a new chat can search again, and the tool selection shows the user the same text.

It decides from the settings alone, not from the data sources the checks of the request let through, because the instructions belong to the cached beginning of the request and must not change whenever an ERI server answers or not. The classic RAG process warns nobody: it searches before the model answers, so the web search ends with the first message which finds something in a restricted data source, and the tool selection then tells the user why. Once the search is gone, no instruction mentions it any more: a call of `web_search` in the same request is refused with the text of `OutboundDataRequirementExtensions.GetToolBlockedMessage`, which names the source and says that a new chat can search again, and the tool selection shows the user the same text.

 **Residual risk.** On `ONLY_LINKS_FROM_CHAT`, the model cannot write addresses, but it still chooses which of the given links to follow. A crafted page with many links could leak a few bits that way, limited by `ToolSelectionRules.MAX_TOOL_CALLS`. Organizations which do not accept this lock the level to `ONLY_CONFIGURED_SERVICES`.

 ## Searching Data Sources

@@ -217,6 +218,10 @@ Every check of an ERI data source signs in to its server, and one message checks

 The data sources are checked again before each search, since rounds may have passed since they were offered, and then searched in parallel. A data source which fails is reported as not searched rather than left out, so that the model does not take its silence for finding nothing. Every passage goes through the same filter and into the same shape as with the classic RAG process, `IRetrievalContext.AsMarkdown`, which gets the scope of one `PromptInjectionGuardService.BeginAction` per search, so that the user hears about what was filtered once per search, as soon as it is done. The result holds whole passages up to 100,000 characters, and the data sources take turns: first the best passage of each, then the second best of each. Otherwise, the data source listed first would take the whole budget. What does not fit is counted in the result, with a narrower query as the way out. An image an ERI server returns is not passed on, in neither process: written as base64 text, it is nothing a model can look at, and it would take more room than all other passages together. The passage tells the model that an image matched and where it is, so that it can point the user to it. What an ERI server says its content is, its category, is passed on as "Source category". The passages become sources through `IRetrievalContext.ToSources()`, as with the classic process, and only the data sources whose passages reached the model raise the requirements of the chat.

+**Where a chat may send data afterward.** A data source holds the documents of the user or of their organization, so each one decides, as a mailbox does, where a chat may still send data once a search found something in it, `IDataSource.OutboundDataRestriction`, see "Outbound Data Restrictions" above. New data sources start with `ONLY_LINKS_FROM_CHAT`, the level of internal pages, and so do the ones saved before the setting existed. What counts is the effective level, `DataSourceOutboundDataExtensions.GetEffectiveOutboundDataRestriction`: the level of the data source, tightened by the minimum of the organization, `DataSourceSecuritySettings.MinimumOutboundDataRestriction`, and to `ONLY_CONFIGURED_SERVICES` for an ERI data source whose security policy is `SELF_HOSTED`. Its data must not leave the infrastructure of the organization through a tool either, while its links into the intranet stay readable: that level still allows the wiki and the allowed private hosts. The rule holds at runtime, so neither a data source saved earlier nor one a configuration plugin provides has to be edited for it; the dialogs only stop offering the less strict levels.
+
+Both ways of searching ask one place what their passages demand, `DataSourceRequirements.Of`, with the data sources and the number of passages each one returned. Only the data sources with passages count, and the strictest effective level wins. On a tie, the data source which comes first by number, then by ID, is the one the chat names, so both ways name the same one, whatever order they searched in. The classic process asks right after retrieval, before the validation agent sees the passages, and counts a passage which that agent drops later as well. This keeps to the safe side, and a validation which fails or is canceled cannot skip the restriction. It sets the restriction on the chat before the request puts its tools together, so the restriction holds for the very answer the passages were found for. Provider confidence and data security stay as they were in the classic process, per selected data source and before retrieval, because its agents see the data.

 ## Searching Mailboxes

 `search_mails`, `read_mail`, and `count_mails` form the collection `mailboxes`, behind the preview `PRE_MAILBOXES_2026` on top of `PRE_RAG_2024`. None of them asks a mail server anything. They read the local index which `MailboxIndexer` keeps, through `MailboxRetrievalService`. Mailboxes are kept in a list of their own, `Data.Mailboxes`, so `semantic_search` and the classic RAG process never see one.
