# 2026-08-27 ISUP inference branch review

## Work Done

Reviewed `feat/isup-inference` against `main` without editing the ve2e repository. Checked the new CLI, patient preparation pipeline, checkpoint loading, forward pass, metrics, JSON output, and logging redaction against existing ve2e and data-pipeline code. Verified actionable issues around environment/package imports, label-dependent study selection, CPU device handling, logging fallback redaction, and broad platform queries.

## Lessons Learned: Pitfalls

The inverse workstream has no SOP index yet, so the mandatory SOP read could not be completed. The macOS checkout cannot run the Linux-only pixi environments, which prevents native runtime tests; static source and lockfile inspection remained useful.

## Lessons Learned: Improvements

Document which repository environment owns cross-project inference commands. In particular, record whether production scripts may import the separate `data` project and how that project must be installed. Add a small inference contract covering unlabeled patients, multiple studies, CPU support, and PHI-safe logging.
