The parser now reads both forms (first call only) and the prompt asks for JSON without markup. +- Agents: runs use an output limit of 4,096 tokens per model call (`limits.max_output_tokens` overrides it) instead of the 1,024-token chat default, which cut long answers mid-sentence. A reply that still stops at the limit is marked as cut off. Providers report this as `ChatResponse.truncated`. +- Agents: when the SQL itself needs a separate approval, the model is told not to retry (it used to file one approval request per retry). +- Text-to-SQL: a cross join against a one-row source (a date window or total in a CTE, `LIMIT 1`) no longer needs approval; cross joins that can multiply rows still do. +- Query results: the suggested chart skips id columns and charts a rate or percentage column on its own when there is one (it used to plot `carrier_id` beside the counts). +- Connections map: shows the platform model ("Platform model", e.g. anthropic · claude-sonnet-5-5) when the organisation has no provider of its own, instead of "No language model configured". + +### Added +- README demo video and screenshots (`docs/media`). + ## 3.0.0 — 2026-11-02 · Enterprise RAG & Knowledge Intelligence Platform A ground-up transformation of CSV-AI v2 (single-user Streamlit app) into a multi-tenant platform.
