GraphQL approach had broken pagination (totalCount key missing, crashes
silently). S3 approach at least completes cleanly even if the metadata
table currently lacks a description column.
- ask.py: Python script to query Base dos Dados via natural language using Gemini,
generates and executes DuckDB SQL from Portuguese questions
- ask/ (Rust): CLI companion for the SQL query assistant with system prompt
- sample_datasets.py: samples parquet files from S3 into a local DuckDB for exploration
- sample_datasets/ (Rust): CLI for dataset sampling
- context/: LLM context bundle (schemas, join keys, file tree) for query generation
- Replace S3 bigquery_tables metadata lookup with paginated GraphQL API call
to fetch table and column descriptions from Base dos Dados
- Add gera_schemas.py for schema compilation and S3 inventory
- Add schemas.json and file_tree.md as generated reference artifacts
- Add websocket proxy in Caddyfile for ttyd on port 7681
- Ignore generated context/ artifacts in .gitignore
- Add openai to requirements.txt
- swap DuckDB UI for ttyd web terminal (--writable, -readonly db)
- add POST /query endpoint with X-Password auth for curl-based SQL execution
- fix UTF-8 rendering: set LANG/LC_ALL=C.UTF-8 in container
- pass BUCKET_REGION env var for correct S3 signing region
- simplify start.sh: drop Xvfb, views.duckdb generation, blocking duckdb -ui
- add less, ncurses-bin to Dockerfile for proper pager/terminal support
- update Caddyfile: single route to ttyd with flush_interval -1 for websocket
- update README to reflect current architecture and document /query usage
- remove duckdb-ui.service, schemas.json, file_tree.md (generated artifacts)
- start.sh: remove prepara_db.py step; load S3 creds via DuckDB init file
- Caddyfile: switch to basic_auth with {env.BASIC_AUTH_HASH} — no rebuild to rotate password
- Dockerfile: drop Python/pip layers (no longer needed at runtime)
- haloy.yml: set server to 89.167.95.136, add BASIC_AUTH_HASH to env
- remove requirements.txt (only needed for local prepara_db.py, not the container)
