- New modelconfig gamma_drift_config.py: 7 params (v, a, z, t, shape, scale, c) in ssms order; bounds are the network's training box (the full ssm-simulators simulator bounds) - Extend SupportedModels and the docstring model lists in lockstep with the config module (the registry gate checks the Literal) Closes #1247 Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new gamma_drift model can fail at fit time until gamma_drift.onnx is published and validated at the configured location, so merge should wait for that release dependency. The external artifact is also not pinned to an immutable revision or digest, requiring explicit owner awareness. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

documentation to include "gamma_drift", matching the list documented in HSSM and
keeping the public documentation consistent.
In `@src/hssm/modelconfig/gamma_drift_config.py`:
- Line 27: Publish and add the missing gamma_drift.onnx artifact referenced by
the gamma_drift model configuration so HSSM(model="gamma_drift") can construct
its default likelihood successfully.

Publish gamma_drift.onnx before merging. The artifact is absent from the repository root and from franklab/HSSM, so HSSM(model="gamma_drift") fails during default likelihood construction.

main gained tests/test_docs_public_reference.py, which pins the reference table in docs/reference/models-and-likelihoods.md to SupportedModels order.
