"""conftest for ANU v3.1 Codex Micro Refinement Loop regression suite (task-2662).

Pinning rationale: the repo-level ``tests/conftest.py`` injects
``WORKSPACE_ROOT`` (default ``/home/jay/workspace``) at the front of
``sys.path``.  Inside this worktree the ``utils`` package only contains the
newly added modules — they are absent in the canonical workspace tree, so
``from utils.anu_codex_micro_refinement_loop import …`` would otherwise
resolve to the canonical (stale) ``utils`` package.

We force ``WORKSPACE_ROOT`` to point at this worktree's root before any
``utils`` import happens, and pop any pre-cached ``utils`` module so the
canonical package is not bound to ``sys.modules['utils']``.
