**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

logret is the continuous log top net-of-tax retention rate in inventor-location regressions. The tax elasticity is not a binary policy-adoption ATT.

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

**90 distinct nonmissing values** in `logret`.

Observed support in the indicated source frame; missing values excluded. N=192; missing=0. Frame: selected_source_data. Source: /Volumes/LAL_BAK/did-cardinality-work/packages/Akcigit_Baslandze_Stantcheva_AER_2016_231370/2015-0237_data/Data_Programs_AER/USPTO/data_estimation/macro_data.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: runs_with_shim. 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.
