# 164 - 2026-03-29: Vision boundary policy metadata

**Status**: ✅ Completed  
**Type**: Vision Contract / Policy Boundary  
**Task**: TASK-121-01-02

---

## Summary

Made the non-truth / non-policy role of the vision layer explicit in the result
contract itself.

The `vision_assistant` payload now carries `boundary_policy`, so downstream
macro/workflow consumers can see that:

- the output is interpretation-only
- it is not the truth source
- it is not the policy source
- correctness still requires deterministic checks
- confidence is non-authoritative

This keeps the richer new fields such as `shape_mismatches`,
`proportion_mismatches`, and `next_corrections` from being misread as proof of
correctness or router policy.
