# DLR Independent Verification Report

## Scope

This report samples the DLR extracted rows against persisted primary-source text produced by `extract_dlr.py`.

Primary source family: Repeatable source family: Digital Realty investor relations quarterly supplement and earnings release materials.

Primary source URL:

https://investor.digitalrealty.com/static-files/953419cb-91ee-4485-8017-26ee0b29bb2a

Companion verification artifacts:

- `source_manifest.csv`
- `source_cache_manifest.json`
- `verification_sample_checks.csv`
- `verification_summary.json`
- `validation_report.json`

## Verification Summary

Status: PASS

sampled_row_count: 12  
pass_count: 12  
fail_count: 0  
rows_matched_to_cached_source_text: 12  

## Method

`extract_dlr.py` fetches primary source files into `sources/raw/`, converts them into persisted text files under `sources/text/`, and extracts rows from those cached text files using repeatable line-pattern matching. The extraction no longer emits rows from embedded snippet constants.

`validate_dlr.py` independently reloads `source_cache_manifest.json`, reads the persisted text files, and confirms that every sampled verification snippet and every extracted row snippet is present in cached source text.

## Normalization Cases

Several USD rows are reported in tables as dollar amounts in thousands and normalized to full USD in `extracted_rows.json`. These are expected normalization cases, not unsupported values:

1. `$422,774 thousand` normalized to `422774000`
2. `$729,959 thousand` normalized to `729959000`
3. `$795,384 thousand` normalized to `795384000`
4. `$2,980,028 thousand` normalized to `2980028000`

## Verification Conclusion

The artifact set now supports a repeatable audit path: source URLs are listed in `source_manifest.csv`, raw and text cache files are recorded in `source_cache_manifest.json`, extraction reads cached source text, and validation checks cited snippets against the persisted source text rather than trusting generated row snippets alone.
