**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

Capital grants are assigned by lottery; the headline interacts winning with peer-ranked ability. The randomized treatment and heterogeneity interaction are not observational adoption.

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

**2 distinct nonmissing values** in `LotteryWinner`.

Randomized grant assignment in the raw tracker; not the generated Winner × peer-rank interaction used in the headline regression. N=1,345; missing=0. Frame: selected_source_data. Source: /Volumes/LAL_BAK/did-cardinality-work/packages/Hussam_Rigol_Roth_AER_2022_151841/PRS_data_replication/data/1_raw/randomization and tracking/treatments and master trackers.dta.

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:** verified; verification: verified; preparation: needs_helper_files. 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.
