# TASK-121-07-01: Checkpoint Comparison Contract and Surface

**Parent:** [TASK-121-07](./TASK-121-07_Vision_Guided_Iterative_Correction_Loop.md)  
**Status:** ✅ Done  
**Priority:** 🔴 High

Define the bounded contract and product surface for comparing one current
checkpoint against the active goal plus attached references.

The repo now has:

- `reference_compare_checkpoint(...)`
- `reference_compare_current_view(...)`

as the first bounded checkpoint-vs-reference comparison surface for staged
manual/reference-guided work.
