# H20 CoVT Reproduction Prep

This folder is an outer wrapper around the public CoVT repository. Do not edit
`upstream/CoVT` when preparing or launching the paper-faithful reproduction.

Remote project root:

```bash
/data/home/user-test/SHC/COVT
```

Public code:

```bash
upstream/CoVT
remote: https://github.com/Wakals/CoVT.git
commit: recorded in checks/upstream_covt_commit.txt
```

Local policy for H20:

- Workspace is for code, files, lightweight CPU checks, and job submission only.
- No direct GPU training/inference in workspace.
- No long-running model/data download in workspace.
- All future GPU or long-download work must use the prepared `jobs/*.sh` scripts
  through `rest-sbatch`.
- Do not read or copy Slurm JWT tokens.
- Do not change server system software, drivers, CUDA, or hardware settings.
- User-level Python packages may be installed only under the user/project scope.

Reproduction target:

- CoVT 3-expert visual-token model: `["sam", "depth", "dino"]`.
- Stage 1 understanding: 6000 optimizer steps.
- Public-code Stage 2/3/4 checkpoint: 10000 optimizer steps.
- Paper Table-6 3-type checkpoint: 11000 optimizer steps, also prepared for
  evaluation because the paper describes Stage 4 as 5000 steps.
- Evaluation: CV-Bench-2D and CV-Bench-3D through CoVT/VLMEvalKit.

Important distinction:

- `upstream/CoVT` remains public source code.
- `scripts/` and `jobs/` only provide paths, Slurm wrappers, manifests, and
  verification around the public source.
