ChatBI Photovoltaic Analytics

Jarvis-zhuang

Chinese-language photovoltaic analytics prototype that routes table and metric context into text-to-SQL, validates and executes queries through a read-only SQLite connection, retries bounded execution failures, and streams traces over SSE. Includes a 31-question synthetic-domain evaluation and committed per-version outputs. No software license is declared.

desk notes

Verified 2026-09-28. Repository commits a synthetic-data generator, 31-question evaluation set (including four refusal cases), evaluation runner, and outputs for four prompt variants. README reports DeepSeek Chat at temperature 0 improving from 11/31 to 23/31 execution-correct after adding a data-date anchor and output contract; the same set was used for iteration, so this is development-set evidence, not held-out performance. Safety includes statement/keyword/multi-statement checks plus SQLite mode=ro, MAX_RETRY=2, MAX_ROWS=200 and a five-second timeout. No LICENSE file appears in the repository tree; treat as source-available research, not legally open source.
