Remarks
A chunk names its own span rather than only the message it belongs to, so a later citation can point at the passage that answered a question instead of at the whole message. StartOffset and the length of Text index the reading of the body named by the rules' source form, which makes the span verifiable: the same offsets applied to the same extracted text return exactly this text.
The remaining source coordinates draft section 12.1 asks a chunk to carry — the account, the folder, the sender, the recipients, the date, and the subject — are the stored email's own columns and are reached through the message a persisted chunk hangs on. They are deliberately not copied here: every one of them is mail content or personal data, and a second copy would widen the access, export, and erasure surface without answering a question the message cannot already answer.
A chunk's text is mail content. Nothing here may be written to a log, a metric, a trace, or an error message; the ordinal, the offsets, and the length are the only members safe to report.
