# Phase 82 Summary

Status: implemented on `main`

## Goal

Replace open-ended runtime dependency ranges with bounded version ranges and
guard them with tests.

## What Landed

- `research/knowledge-hub/requirements.txt` now uses bounded ranges for `mcp`
  and `jsonschema`
- new contract test:
  `research/knowledge-hub/tests/test_dependency_contracts.py`

## Outcome

Phase `82` is complete.
`v1.50` is active on a bounded dependency baseline.
