Summary
FireANTs registration API and tests src/monai_physio/register_images_fireants.py, src/monai_physio/__init__.py, tests/test_register_images_fireants.py, .github/workflows/*
Adds and exports a FireANTs registrar for rigid, affine, and deformable registration. GPU tests cover settings, transforms, masks, physical geometry, and workflow integration. GPU workflows install FireANTs without resolving dependencies.
Benchmark and affine diagnostics experiments/Registration-Fireants_vs_Greedy/benchmark.py, experiments/Registration-Fireants_vs_Greedy/affine_diagnostic.py, experiments/Registration-Fireants_vs_Greedy/tuning_compare.py
Adds tools to time Greedy and FireANTs registration, record image and transform metrics, inspect affine results, and compare tuning runs with phase-matched Greedy baselines.
Adds a Markdown report generator for benchmark, tuning, held-out phase, affine diagnostic, and limitation data.

Layer / File(s)
Summary
Inference constructors and tutorial src/monai_physio/infer_physicsnemo_*.py, docs/developer/migration_next.md, tutorials/tutorial_18_duke_heart_physics_informed_motion_infer.py
The base, MGN, and MLP constructors accept model_tag and log_level. The migration guide documents the arguments, and the inference tutorial passes a configured MGN instance.
Updates lint annotations, parsing and exception handling, timestamps, image-size calculations, VTK/USD utilities, and script behavior. Adds a test for TotalSegmentator configuration.
Tutorial behavior and reporting tutorials/*, experiments/Heart_and_Lungs_Motion/0-heart_and_lungs_beating_heart.py
Updates Xvfb exception suppression, motion-cycle settings, stage logging, and descriptions of leave-one-out metrics.

The loop is **automated**. A human halt is a cost; every halt must be justified.
1. **Ask everything once, up front.** Before generating the kit, anticipate every question the run could raise and put them in ONE batch (use AskUserQuestion, or a single list): decisions and tolerances; data/mode choices; dependency installs and environment quirks (version pins, Windows/platform gaps, plugin conflicts); approval for expensive jobs; whether the supervisor may run the verifier itself; and **standing authorizations** for predictable amendments (verifier/environment fixes, baseline-relative lint rules, schema/path naming mismatches, API differences discovered in Phase 0). Do not trickle questions between steps.
2. **Standing authorization replaces per-step gates.** Record the answers in `TASK.md` and the supervisor skill. After that: the supervisor runs worker -> verifier -> reviewer -> decision and **auto-advances** to the next slice when the verifier is PASS and the reviewer has no blocking findings. [H] items are treated as confirmed under the standing authorization unless the human reserved them in the batch. Never end a turn with "waiting for acceptance".

Do not treat standing authorization as [H] evidence.
Line 60 defines [H] as human-confirmed, but this rule treats every [H] item as confirmed unless the human reserved it. A standing authorization is not confirmation of an outcome, so a slice can advance without its required human evidence. This also conflicts with Line 56’s human acceptance gate and Line 116’s requirement to present findings for human acceptance. Require a recorded human decision for each [H] item and make the slice-advancement rule consistent with that gate.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win
Keep the trusted verifier outside the supervisor’s repair authority.
The README places the reference verifier outside the repository, and its output is part of the authority chain. This rule lets the supervisor change that verifier and then use its output as evidence. If a repair weakens a check, the resulting verification.json can still authorize the same run. Require human review and installation of verifier changes before a new run. Limit automatic repairs to environment issues that do not change verification criteria.
Proposed change
- - Verifier/environment defects (outside the repo), schema/name mismatches, and pre-existing-lint baselines are fixed by the supervisor, re-verified under a new run id, and logged in `PROGRESS.md`. Contract-semantics changes that stay inside the pre-authorized classes are applied as amendments (re-freeze, refresh the control hashes) without asking.+ - The supervisor may fix environment defects that do not change verification criteria. If a verifier change is needed, mark the run `BLOCKED` until the human reviews and installs the revised verifier. Re-run under a new run id and log the resolution in `PROGRESS.md`.

torch.cuda.empty_cache() runs for Greedy runs too.
Line 441 calls torch.cuda.empty_cache() for every method. sync() correctly gates CUDA calls on self.cuda, but this call has no gate. hardware_info also calls torch.cuda.get_device_properties(0) without a gate. On a CPU-only host, a Greedy baseline run therefore fails. The report says Greedy ran on the CPU, so the script must support that run. Gate both calls on CUDA availability.
Proposed fix
gc.collect()
- torch.cuda.empty_cache()+ if self.cuda:+ torch.cuda.empty_cache()

This conclusion reports success regardless of the input statistics. For example, Greedy NCC of 0.9 and tuned NCC of 0.8 still produce “meets the NCC and neg-Jacobian constraints,” even if the tuned negative-Jacobian fraction is also worse. Derive the verdict separately for each dataset from the measured values, and distinguish the all-phase result from the held-out check.
