 # Changelog
 
+## Unreleased - Grouped questions (analyze_records)
+
+- New read tool `analyze_records`: group a table by one or two fields (optionally a date field by year, quarter, month, week, day or hour) and compute one number per group: a count, or a sum, average, minimum, maximum or distinct count of a field, with the same filter the other tools take (relative dates included). "How many documents were printed in the last day, by format?" is one tool call, and the groups carry links that open their records.
+- It is one call of the data-analysis qbit's pivot operation (`POST /qbit/data-analysis/tables/{table}/pivot`, UI API extension `data-analysis`), made through the same gateway with the user's own session, so table read, the table's analyze permission, field access and record locks decide exactly as on the Analyses screens; a refusal reaches the model with the same status and message. The assistant only narrows it: the table's data access must allow reads, group-by, measure and filter fields must be fields whose values the assistant may see, and the policy's row cap bounds the groups returned.
+- The tool is offered only where the `data-analysis` extension is registered. The assistant gets no dependency on that qbit (test scope only). Relative dates in an analysis filter need qbit-data-analysis 0.3.0-RC.2 or later (earlier versions answer HTTP 500 for them).
+
+## Unreleased - A turn always ends
+
+- Fixed an answer that stayed on "Thinking..." forever (seen after the tool steps had finished) when the host database stopped answering, for example a connection pool with every connection checked out. The watchdog's heartbeat did its database read and write while holding the engine's monitor and before it checked the deadline, so one blocked heartbeat stopped the deadline from ever firing and stopped `finish` from running. The deadline is now checked first on every tick without touching the database; the heartbeat, cancel poll and kill-switch poll run on a separate bounded worker that is reported (WARN), interrupted and abandoned if it does not return within two heartbeat intervals; and the engine's monitor is no longer held across database I/O in the heartbeat or while waiting to finalize.
+- A finalize guard ends the live stream with an `error` event and `message.end` if the terminal save has not completed within `turnForceFinalizeGraceSeconds`, so the panel never waits on the database to be told the answer failed. The terminal row is left for lease recovery.
+- New INFO log lines for every phase: `Assistant turn started`, `Assistant model call started` / `finished`, `Assistant tool call started` / `finished`, `Assistant turn finalizing`, `Assistant turn finished` (no message content). WARN lines when the deadline passes, when the watchdog finalizes a turn, when a heartbeat does not return, and when the guard ends a stream.
+
+## Unreleased - Answer visible at the end of the stream
+
+- The turn's redacted transcript (the question and answer parts, pending actions, stored events) is now written before `message.end` is sent. The panel reloads the conversation the moment the stream ends, and used to read the empty placeholders (`[]`) the transcript redactor stores until its flush, so the newest question and answer showed as empty bubbles until the panel was closed and reopened.
+
+## Unreleased - Clear reason without a model provider (UI API extension 1.7.0)
+
+- `GET /config` checks the server-wide causes before the user's permission: `DISABLED`, then `NOT_CONFIGURED` (no usable model provider), then `NO_PERMISSION`, then `KILL_SWITCH`. A server with no provider no longer tells users to ask for access (#82).
+- UI API extension assistant 1.7.0: `GET /config` has `message` whenever `reason` is set: a sentence for the user. For `NOT_CONFIGURED` it says what an administrator configures (an enabled row on **Assistant > Providers**, for example Anthropic with `ANTHROPIC_API_KEY` set in the server environment, or a local OpenAI-compatible server such as Ollama).
+- Without a usable provider, calls from a user who also lacks `assistant.hasAccess` answer `503 NOT_CONFIGURED` with that message instead of `403 NO_PERMISSION`; users with access keep their conversations, and a new question answers `503 NOT_CONFIGURED`.
+- Verified the OpenAI-compatible adapter (kind `OLLAMA`) live against a local Ollama `llama3.3:70b-instruct-q4_K_M`, including a tool call (`LiveOpenAiCompatibleTest`).
+
 ## Unreleased - Conversation management (UI API extension 1.6.0)
 
 - `assistant_conversation` is open to every assistant user (`assistant.hasAccess` or `assistant.admin`, through the new `AssistantAccessPermissionChecker`) in the standard table UI. Rows stay locked to their owner by the `userId` record lock, so a user only ever sees, updates and deletes their own conversations; admins with the all-access key still see everyone's. The Assistant app (its nav) and every other assistant table stay admin-only.
