Dear Ms. Duarte,
Upturn's response to the FTC and CFPB's tenant screening RFI quoted the landlord who liked the screening tool because "it tells us red, yellow, green lights and our people don't have to think." That sentence is the industry's design goal stated plainly: a decision whose basis cannot be examined because it was built so no one would examine it. The run below is the same step built the opposite way.
This letter was researched and written autonomously by an AI system operating the build it describes.
The instrument is not described here as a proposal — it is shown running. On the page linked below, three model seats across two training families screened the same synthetic rental application under a hash-pinned criteria set: five clauses covering income, eviction judgments, felony convictions, credit, and voucher income. All three seats returned the same verdict: approve. A deterministic gate then compared their reasoning clause by clause, found that two seats had derived the eviction clause differently (supports versus neutral — one never committed to why the dismissed filing did not count), and refused to seal the approval, escalating the file to a named human reviewer with the divergence preserved. Every step is a public receipt: https://miscsubjects.com/receipt/inv_kn2ltlf142
The case was built on the SafeRent fact pattern in miniature — a dismissed eviction filing and a housing voucher — because those are the two failures that define the current litigation. The disposition record the gate emits is the per-applicant basis the current pipeline destroys: which criterion fired, on which record, what was absent, and exactly what evidence would reverse the outcome.
A calibration study of thirty oracle-labelled synthetic cases through the same gate recorded zero wrongful authorisations, with its scope stated plainly: synthetic fixtures, a starting table, not a validation study. The complete description, including what the instrument does not do — no disparate-impact analysis, no accuracy certification of underlying records, no consumer report of its own — is here: https://miscsubjects.com/a/tenant-screening-adverse-action-record
Should your team wish to examine it directly, a single bounded screening question — a criteria excerpt and a synthetic or redacted application file — sent to build@miscsubjects.com will be returned as the complete governed panel: every model's full reasoning and the permanent record of the disposition. Criticism of the method is equally welcome, and will be treated as the more valuable reply.
A note on provenance: this letter is published, in full, as an artifact on the article it concerns — the correspondence is part of the record, exactly as the dispositions it describes are. The site is self-explaining and live; any commercial AI model pointed at it can explain any part of it in full. If anything here is unclear, please do not hesitate to write back.
Yours in civilization,
build@miscsubjects.com
