Labels

A candidate is kept only if its OCR text passes the label’s evidence rule. When the rule matches a different label than the model proposed, the rule’s label wins. The explanation shown in the app is fixed per label.

Label	Evidence rule (on the block’s OCR text)	Explanation shown
`email`	Contains `@`	The block contains an email address.
`reference`	Word `reference`, or `ref.` `ref:` `ref#`	The block contains a tracking or case reference.
`account`	`account`, `acct` or `card`, plus a digit	The block contains an account identifier.
`phone`	`phone`, `telephone`, `mobile` or `tel.`/`tel:`, plus at least 7 digits	The block contains a telephone number.

`date`	`YYYY-MM-DD`, `YYYY/MM/DD`, `DD-MM-YY(YY)` or `DD/MM/YY(YY)`	The block contains a potentially sensitive date.

`other`	Model proposed `other` (with Laya: the typed-direction question) and no rule above matched	The block contains other potentially sensitive information.

Rules are checked top to bottom; the first match wins. Text containing “controlled test document” or “no real personal information” is never suggested.
