Original collectionUnder development

Under development — library extension. This report is part of the expanded-library work, not the original collection. Source preparation, methods and results are subject to revision.

Provisional eligibility assessment — under development. Deep DiD follow-up: The authors separately estimate KCHA 2016 and SHA 2018 policy DiDs (lines 54–64 and 130–140); the latter explicitly drops experimental treatment families (lines 87–91). This is not the main randomized mobility intervention. The historical administrative data require access; no successful run or ready adapter is implied. This working assessment is not fully vetted and may change. See the report below for its recorded replication or assessment status. Provisional eligibility log

Under development — community extension. This is a provisional source-design assessment, not a new successful replication or a final eligibility ruling.

Source design and template applicability

CMTO housing-search services are randomly assigned. The high-opportunity lease-up contrast is experimental and its confidential household inputs are not deposited.

No DiD estimates, uncertainty intervals or homogeneity-test decision were computed in this tranche. No point is added to the calibration plots. This is not a zero effect or a failed statistical test.

Recorded treatment-column measurement

Data unavailable.

Confidential CMTO participant-level assignment/analysis records are not deposited; only code and aggregate artifacts are present.

These are the existing data-measured counts, not counts inferred from design labels. A binary instrument, group indicator or interaction component need not be the treatment of interest; the source-design assessment above takes precedence for template applicability.

Replication status

This tranche: unsupported design; source code/documentation inspected, no estimator run.

Supplied library: no_did_analysis_data; verification: no scalar DiD target; preparation: needs_restricted_data. These are the library’s labels, not new verification claims. Missing data and unsupported designs are separate issues.

Evidence and provenance

The following files in the supplied library were inspected. Their SHA-256 digests are recorded in the downloadable assessment JSON. Source archives and microdata are not redistributed.
