Remarks

This is the only shape mail content travels in on its way to a model. It carries an extract rather than a message: the bound is applied before the passage exists, so nothing downstream can widen it, and a retrieval that matched a long thread hands over what was relevant rather than the thread.

The identity travels with the text because an answer that cannot say where a claim came from cannot be checked. The stored identifier is the same one every other read names an email by, so a reader given a passage can fetch the whole message; the account and the folder alias are the deployment's own names for where it was read from.

A passage is mail content and inherits the classification of the message it was cut from. It is never logged, never attached to a span, and never exported.
