Phase 1: Inventory

• Status: in_progress
• Started: 2026-05-27
  • Actions taken:
  • Loaded required conversation-start skill.
  • Listed repository files.
  • Checked git branch and dirty state.
  • Checked for repo instruction files.
  • Created audit planning files.
  • Files created/modified:
  • task_plan.md
  • findings.md
  • progress.md

Phase 2: Architecture Review

• Status: in_progress
• Actions taken:
  • Read training entrypoint, trainer registry, base trainer, supervised trainer.
  • Read segmentation configs and experiment scripts.
  • Read local ignored data package implementation.
  • Read XNet2d model implementation and tool modules for loss/metrics/optimizer/config.
  • Checked dependency/import availability and syntax compilation.
• Files created/modified:
  • findings.md
  • progress.md

Test Results

Test	Input	Expected	Actual	Status
Dependency import check	python import selected packages	Core packages import	Only yaml imported; ML dependencies missing	Partial
Syntax compilation	python -m py_compile ...	No syntax errors	Passed	Pass
Dependency import check in xnet_mamba	import selected packages	Core packages import	torch, monai, ptwt, timm, triton, PIL import; pytest and swanlab missing	Partial
XNet2d shape test	direct call to tests.test_xnet_2d in xnet_mamba	seg_logits shape equals input spatial size	Passed	Pass
BUSI split check	scripts/generate_project_split.py --dataset BUSI --root data/BUSI --seed 42	Train/val splits load	624 train, 156 val	Pass
CPU smoke training	1 epoch small BUSI run on CPU	Training loop completes	Failed in VMamba cross_scan_fn: expected cuda device, got cpu	Fail
CUDA smoke training	1 epoch small BUSI run on CUDA	Training loop completes	Passed 312/312 steps, final total loss 0.8458519516847073	Pass

Phase 5: Readiness Fixes

• Status: complete
• Actions taken:
  • Updated .gitignore to keep /data/ ignored while allowing lib/data/ tracking.
  • Added root requirements.txt.
  • Added tests/test_xnet_2d.py.
  • Verified syntax compilation.
  • Verified XNet2d shape behavior in xnet_mamba.
  • Verified BUSI project splits.
  • Ran CPU smoke and recorded VMamba CPU limitation.
  • Ran CUDA smoke successfully.
• Files created/modified:
  • .gitignore
  • requirements.txt
  • tests/test_xnet_2d.py
  • task_plan.md
  • findings.md
  • progress.md

Error Log

Timestamp	Error	Attempt	Resolution
2026-05-27	CPU XNet2d/Trainer fails with ValueError: Expected a cuda device, but got: cpu in lib/modules/lib_mamba/csm_triton.py	Direct shape test and CPU 1-epoch smoke	Shape test disables global branches on CPU; full smoke verified on CUDA
