Values as read by Gemma-4-31B-IT (whole sheet + 3 zoomed strips (page + 3 strips, docs/sources/ledger-rescue-pilot.md §3)). Amber shading: a routed year. Orange numbers differ from the volunteers' transcription (hover for their value); the gate never sees the volunteers' values, they only grade it.
