feat: herculens power-law parity script via COOLEST#175
Merged
Conversation
…ia COOLEST Cross-code validation of PowerLawIntermediate <-> herculens EPL through a shared COOLEST template: identity theta_E mapping, convergence and deflection-angle parity on a shared grid, spherical limit, and the from_coolest(intermediate=True) round trip. herculens installed in this env only (never a library dependency). Part of PyAutoLabs/PyAutoLens#616. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Summary
Adds
scripts/coolest_herculens_parity.py(PyAutoLens#616): cross-code validation thatag.mp.PowerLawIntermediateand herculens'sEPLare directly linked through the COOLEST standard — the same template parameters (identitytheta_E, no √q factors) produce numerically matching convergence and deflection angles on a shared grid, including the spherical limit and thefrom_coolest(intermediate=True)round trip. All checks PASS in this session (herculens 0.3.0 installed in the env only; probe confirmed herculens EPLtheta_Eis the COOLEST intermediate-axis convention exactly).Scripts Changed
scripts/coolest_herculens_parity.py— new cross-code parity validation script (run this session, all PASS)Upstream PR
PyAutoLabs/PyAutoGalaxy#503, PyAutoLabs/PyAutoLens#617 — merge library first
Test Plan
python scripts/coolest_herculens_parity.py— 5 PASS lines; additive-only change (no existing script touched).Generated by the PyAutoLabs agent workflow.
