Travel email classification proof.

A redacted or synthetic proof for a B2B travel agency inbox. Gmail-style emails are classified into operational categories, written to a Sheets-ready status queue, escalated to Slack drafts only when urgent, and blocked for human review when ambiguous or loop-prone. No client data, connected accounts, booking engine, live Slack post, or customer email send is used.

Six redacted or synthetic Gmail-style rows across hotel updates, urgent booking changes, invoices, ambiguous messages, auto-replies, and missing account keys.

Accepted

Three rows become classification ledger entries and Sheets-ready status rows, with one urgent row drafted for Slack review.
