    - When all IDs on the current page are in the reviewed set, advance to the next page.
    - Stop when a page returns fewer results than the page size (end of folder) and all its IDs are in the reviewed set.
 5. For each single envelope ID, do all checks before any move/delete:
+    - Check envelope flags from the JSON listing (seen/answered/flagged) before reading.
     - Read the message: `himalaya message read -f "<source>" <id>`.
     - If needed for classification, inspect attachments: `himalaya attachment download -f "<source>" <id> --dir /tmp/himalaya-triage`.
     - If attachments are downloaded, inspect them and `rm` the downloaded files from `/tmp/himalaya-triage` after use.
     - Move: `himalaya message move -f "<source>" "<destination>" <id>`.
     - Delete: `himalaya message delete -f "<source>" <id>`.
 6. Classification precedence (higher rule wins on conflict):
-   - Human communication — a message with freeform natural-language content written by a human, not templated or autogenerated. When in doubt whether a message is human or automated, leave it untouched.
+    - **Actionable and unhandled** — if the message needs a reply, requires manual payment, needs a confirmation, or demands any human action, AND has NOT been replied to (no `answered` flag), leave it in the source folder untouched. This is the highest-priority rule: anything that still needs attention stays in `INBOX`.
+    - Human correspondence already handled — freeform natural-language messages written by a human that have been replied to (`answered` flag set): move to `Correspondence`.
+    - Human communication not yet replied to but not clearly actionable — when in doubt whether a human message requires action, leave it untouched.
     - Clearly ephemeral automated/system message (alerts, bot/status updates, OTP/2FA, password reset codes, login codes) with no archival value: move to `Deleted Messages`.
-   - Payment transaction correspondence (actual charge/payment confirmations, receipts, failed-payment notices, provider payment events such as Klarna/PayPal/Stripe): move to `Payments`.
+    - Automatic payment transaction notifications (charge/payment confirmations, receipts, failed-payment notices, provider payment events such as Klarna/PayPal/Stripe) that are purely informational and require no action: move to `Payments`.
     - Subscription renewal notifications (auto-renew reminders, "will renew soon", price-change notices without a concrete transaction) are operational alerts, not payment records: move to `Deleted Messages`.
     - Installment plan activation notifications (e.g. Barclays "Ihr Ratenkauf wurde aktiviert") are operational confirmations, not payment records: move to `Deleted Messages`.
