…e, 435 datasets Bumps to 0.3.0. Every build now writes a canonical Arrow IPC file and exports each format from it through a registered writer. Seven writer lanes (pyarrow, arrow-rs, parquet-java through parquet-arrow-java, Hardwood, and Vortex through Python, Rust and JNI) are measured against each other by a conformance harness whose ledger ships in docs/v2/compliance.json. Every writer reads back what it writes, and a format a writer cannot produce is recorded with the measured failure instead of a hand-written reason. The catalog grows from 250 to 435 datasets, including generated TPC-H and TPC-DS tables, and gains versioned catalog bundles, native readers for Rust, C, C++ and Java, and the raincloud command. It is a breaking release: the pipeline moves from scripts.pipeline to raincloud.pipeline, default data locations move to the platform's user directories, schema_version becomes 2 (outputs/v2 and docs/v2), and reads no longer build by default. Ingest no longer drops upstream records or values: JSONBench rejoins the 16 records its dumps wrap, and uci-thyroid-disease, uci-diabetes and uci-online-retail-ii keep what they used to lose. CHANGELOG.md has the full list. Co-Authored-By: Claude <noreply@anthropic.com> Signed-off-by: Martin Prammer <martin@spiraldb.com>

Cuts 0.3.0. Every build now writes a canonical Arrow IPC file and exports each format from it through a registered writer, and a conformance harness measures seven writer lanes against each other: pyarrow, arrow-rs, parquet-java through the parquet-arrow-java bridge (a submodule, pinned to its v0.2.0 release), Hardwood, and Vortex through Python, Rust and JNI. Its ledger ships in
docs/v2/compliance.json; the only failures it records are two upstream Hardwood 1.1.0.Beta1 reader bugs. Every writer reads back what it writes, and a format a writer cannot produce is recorded with the measured error rather than a prose opt-out. The catalog grows from 250 to 435 datasets and gains versioned catalog bundles, native readers for Rust, C, C++ and Java, and theraincloudcommand.This is a breaking release. The pipeline moves from
scripts.pipelinetoraincloud.pipeline, default data locations move to the platform's user directories,schema_versionbecomes 2 (outputs/v2,docs/v2), and reads no longer build by default; the Changed section ofCHANGELOG.mdis the upgrade guide. Tagv0.3.0and the GitHub release follow on merge.🤖 Generated with Claude Code
