Changelog

0.4.0 — 2026-10-31

M0–M3 全部里程碑。

SQL-first pipeline: source (CSV / Parquet / JSON / table / SQL), sql, assert, sink (table / Parquet / CSV)。
Transactional runs with rollback; staged-file + rename for file sinks.
Run history in a separate DuckDB file (_etl.runs, _etl.steps, _etl.watermarks).
Incremental watermarks for table sinks (append / upsert); updated only after commit and file installation.
Partitioned Parquet sinks (partition_by) with staging-directory replacement.
DuckDB extension loading via pipeline extensions.
Cooperative cancellation via duckdb_interrupt; canceled status recorded.

Dashboard / Sources / Pipeline / Run screens.
Pipeline draft editor: add/delete steps, field forms, enum toggles, inline editor, $VISUAL/$EDITOR for SQL, atomic save with validation.
Run monitoring, log, per-step SQL, preview (LIMIT 100).
--isolated runs the pipeline in a ducketl worker child process; worker crash leaves the TUI running and marks the run failed.

ducketl run, tui, worker, extensions, validate, list, show, version.
ducketl worker speaks JSONL on stdout and accepts cancel on stdin.

252 tests across 10 files: SQL scanning, validation, planner SQL, execution, rollback, atomic files, CLI, TUI rendering/form logic, watermark/partition/ extension behavior, isolated worker cancel and crash handling.
