"""Regression for #110597: Copilot custom/enterprise (BYOK) model ids must survive normalization.

GitHub's enterprise custom-model (BYOK) catalog exposes Copilot ids shaped ``owner/sub/model``
— that is, TWO slashes. With no candidate matching the (unreachable) catalog,
``normalize_copilot_model_id`` stripped the FIRST path segment and returned the result:
``acme-github-copilot/GLM/glm-5.2`` became ``GLM/glm-5.2``, the CLI's second normalization pass
stripped again to ``glm-5.2``, and the Copilot API answered HTTP 400 ``model_not_supported``.
Every such call failed, for both custom models a tenant had configured.
