Description
glass is pinned to ==2025.1 alongside glass-ext-camb==2023.6 and cosmology==2022.10.9. glass 2025.2 dropped the cosmology package in favour of cosmology.api, and sp_validation/glass_mock.py (l.181, l.224) and scripts/glass_mock/make_unions_glass_sim.py (l.321) still do from cosmology import Cosmology and pass that object to glass.distance_grid. Renovate's glass-2026 PR (#329) was closed for this reason and will stay closed until this is done.
Done when: the mock code uses the cosmology.api protocol (or glass's own cosmology adapter), the three pins are replaced by floors, and a mock generated with the new glass reproduces the fiducial 2025.1 result (same seed → same shear maps, or documented difference).

Research direction
Inspect the dependency declarations for glass, glass-ext-camb, and cosmology, then read the imports and glass.distance_grid calls in sp_validation/glass_mock.py at lines 181 and 224 and scripts/glass_mock/make_unions_glass_sim.py at line 321. Update the mock path for the cosmology.api protocol or glass adapter, replace the three pins with floors, and verify that a new mock matches the fiducial 2025.1 result with the same seed or documents the difference.
