Add audited original multilingual mailroom dataset

Adds mailroom-control-v1 with 114,800 original typed records, 11,600 email requests and 400 multilingual families in five splits. Includes exact raw JSONL, Parquet, original manifest, auxiliary cases, independent visible-text audit, expansion preservation and pinned source links. No private emails or provider responses are imported. No training or full-corpus model evaluation is claimed; a separate 87-request Jev probe is documented. Existing payloads, configs, manifests, default and frozen mixtures are preserved, including the preceding IR addition.

 # Open-Jev: typed decision datasets
 
-Open-Jev turns a state and a question into a typed decision: a yes/no probability, a distribution over choices, independent label probabilities, or a discrete numeric/ordinal decision. This repository publishes eleven separate, frozen data configs from the [Open-Jev project](https://github.com/Zefan-Cai/Open-Jev-Dev), together with original manifests, exact raw records, source code and reconstruction instructions.

+# Original multilingual mailroom controls
+
+**114,800 typed rows, 11,600 email requests and 400 whole synthetic families.**
+Original English, Chinese and Turkish emails and labels are CC0-1.0. Source
+code is MIT. No real mailbox, source emails, IMAP contents, attachments or the
+community author's private examples were imported.
+
+The [pinned community implementation](https://github.com/selcukusta/jev-mailroom/tree/06d44889231afb209e29275f14a529ba52c9eb0d)
+asks two Choice and nine Noul questions, eleven total. Our implementation
+preserves state shape `email.subject`, `email.from`, `email.date`, `email.body`
+and the eleven-head contract with independently authored question wording.
+
+`kind` distinguishes invoice, payment confirmation, account statement,
+promotion, newsletter and other. Four evidence Nouls ask about currently owed
+money, the sender issuing its own charges, billing identifiers and promotion.
+`category` distinguishes education, electricity, telecom, banking, airline and
+other; five independent Nouls also ask about these subjects. Category is
+unsupervised for nonbill/nonreceipt messages: 4,800 requests retain the runtime
+question but omit its training label. An application fallback is not ground truth.
+
+Already-paid amounts and advertised prices are not currently owed money.
+Invoice links without repeated amounts remain invoices; relaying a bill does
+not make the relay its issuer. Controls distinguish educational services from
+a student's phone bill, handset retail from telecom service, equipment from
+electricity supply, bank-mediated payment from a bank's own charges, and known
+out-of-taxonomy services. Unknown or contradictory grammar is not assigned gold.
+
+Each family contains three languages and nine actions, plus two English invoice
+taxonomy variants. Reordering categories tests order sensitivity; adding
+insurance changes the insurance label only when that option exists. No change
+in confidence is assumed or supervised. Shared unchanged question inputs across
+taxonomy variants reference their first row. There are **114,800 unique ordered
+inputs**, or **114,400** when candidate order is also disregarded.

+| validation | 6,027 |
+| test | 8,323 |
+| ood | 22,960 |
+
+All translations, actions, services and taxonomies for a family share a split.
+Index modulo ten values 8–9 reserve OOD; other families use stable hashing.
+OOD reserves fictional identities and moves body paragraphs when possible;
+two-paragraph messages retain their order. It is not a new grammar for every
+request. The frozen 10-family probe stays byte-identical in the expanded corpus,
+including all 290 requests and 2,870 rows in their original split files.
+
+Use only state, question, kind and options as model inputs. Targets, metadata,
+case reference labels and masks are privileged audit fields. Each Parquet
+`record_json` and decompressed raw split retain exact original JSONL bytes and
+row order, with the same column schema as the existing configs.
+
+**No training on this corpus is claimed.** A separate real Jev 1.13.0 probe
+completed 87 held-out requests containing 957 runtime questions and 921 labelled
+decisions; 36 category questions had no gold. Its 908/921 correct decisions are
+a small correlated control probe, not full-corpus evaluation or production
+multilingual accuracy. No provider responses are included in this data upload.
+The generation manifest records operations at generation time; later probe
+evaluation is documented separately. Frozen model-training mixtures are unchanged.
