**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.
