Dataset versions

A dataset version is a capture of the source as of a date: its event spine and the files training reads.

apache__airflow@asof-2026-07-29 — data stage report

Recorded 2026-10-13 as part of the OSS line's migration to the factory. The data already existed and nothing was rematerialized.

Inputs, by identity. GitHub's event API for apache/airflow, materialized into the OSS canonical spine. Pooled8 member. The raw captures stay external, on the archive drive and Modal.

Output, by identity. canonical_events.jsonl, 1,128,527 events from 2020-01-01T00:11:23Z to 2026-07-29T16:05:46Z. The spine is recorded where it already is (Modal, rezendi, vei-oss-data/apache__airflow) and not copied into the registry.

Drift. Ingest-time check (drift.json, drift.txt): 1,128,527 events over 79 periods | structural types excluded: none; 24 verb flags, 5 volume flags. The OSS runs split each stream at its own time quantile, so no single calendar split applies across the pooled streams, and no split-time check was run here. Its absence is a caveat on any result.

02 · Features

Featurization

An Atlas recipe declares how events become model inputs.

No feature recipe has been recorded.

An Atlas recipe appears here once a run that names it is published, or once the recipe itself is registered.

03 · Training

Recipes and runs

A Praxis recipe fixes the model, the objective and the split.

No run has been published.

A run is one execution of a training recipe over named dataset versions. The first one born inside the platform will appear here with its launch.

04 · Evaluation

How it compares to other methods

No results have been published for this project.

A result is a cell: the config, the target at a horizon, the arm and head, the split, the numbers and their provenance.

Needed: an eval config and an eval run of a published model

05 · Serving

Ask the model

If the query service is cold, it will need a few minutes to warm up.

Nothing is serving yet.

A published run with a report or a query surface answers here.
