Unattended delivery (POD pointer)

Workflow (mapping-only)

Use Waybill block (hash default; last4 opt-in only).
Set event: delivered_unattended.
Choose drop location enum (e.g., porch/door/mailbox/reception/locker/other).
Create POD pointer: hash the POD photo locally and store the photo in a private appendix (local-only).
If receiver needs more: MER (≤3) requests missing evidence from taxonomy.

Integrity signal only — not a legal outcome.
