Dataset

Synthetic ingestion source, deliberately defective

This record documents 8 exposures from Invented, defective on purpose. Access is public. Source-defined outcomes, limitations and provenance are documented below.

CautionSynthetic fixture, defective on purpose

Every value in this file was invented to make each gate fail at least once. The defects are deliberate and the file must never enter a benchmark or a published release.

RestrictedThis normalised version cannot become benchmark-eligible

Twenty-nine findings were raised across the fifteen gates, twenty of them at fail severity.

Overview

The file declares nine records and supplies eight. That single mismatch is one of the defects, and the source metadata consistency gate catches it.

Each row's notes field states which defect it carries.

Source and citation

As with the clean fixture, the file carries no source URL, no accession reference, no citation and no retrieval date. Its label field states that the defects are deliberate.

Population and exposures

Eight rows reach the gates. Their profile values include an impossible ambient pressure, a negative duration and a discontinuity, so the numbers describe defects and not exposures.

Outcomes

Two findings come from the outcome code validity gate. The codes in those rows sit outside the vocabulary the file declares, which is what the gate exists to catch.

Does not exist for this source

No outcome class is assigned to this file, because outcome parsing fails on it by design.

Variables and units

The source vocabulary matches the clean fixture. One row declares a unit the parser cannot resolve, and the unit ambiguity gate raises a fail finding on it instead of guessing.

Source vocabulary declared in the fixture, and the canonical unit the parser converts it to under the canonical data contract.

Missingness

One finding comes from the missing required fields gate. Missingness on this file is a defect under test and carries no information about how a real source behaves.

Model-development history

Does not exist for this source

No model was developed or calibrated on this file, and the leakage registry holds no relationship pointing at it.

OpenDeco normalization

The parser still produces a normalised version from a defective source, and that version is hashed like any other. Normalisation and acceptance are separate steps, so a file can have a stable content address and still be refused by the gates.

Quality flags

Zero gates pass and fifteen fail. Twenty-nine findings are spread across three severities: three at warning, six at quarantine and twenty at fail.
